This 21 Day Fix Mexican Lasagna is more than just a family favorite; it’s a culinary masterpiece that seamlessly blends wholesome ingredients with incredible flavor! It’s also incredibly versatile, making fantastic leftovers for quick and easy lunches throughout the week. If you’re looking for a satisfying comfort food that aligns with your health goals, you’ve found your new go-to recipe.

21 Day Fix Mexican Lasagna, a family favorite meal.

As a fit food enthusiast, I’ve learned that certain events, like a massive snowstorm, tend to spark an insatiable craving for hearty, comforting meals. And let’s be honest, they also might lead to a few extra sips of wine! This past weekend’s blizzard certainly put my “yellow” container counts to the test. That’s precisely why recipes like this 21 Day Fix Mexican Lasagna are absolutely essential. It’s the perfect answer to those comfort food cravings, delivering cheesy, deliciousness without derailing your healthy eating plan.

Initially, I encountered a popular Mexican Lasagna recipe within my challenge group (which, by the way, is an incredible community!). Everyone was raving about it, especially during the blizzard. However, upon closer inspection, the container counts felt a bit off. Specifically, the “one yellow” claim for the original recipe didn’t seem quite right to me; it looked like there was definitely more than one yellow serving there. I pondered simply recalculating and proceeding, but after another glass of wine (hey, it was a blizzard!), I knew I had to make some adjustments to ensure it genuinely fit the “one yellow” category for the 21 Day Fix program.

So, I set out to “fix” it. My mission was to create a truly compliant and equally delicious version. I carefully reduced the number of tortillas and scaled back on the refried beans, hoping these changes wouldn’t compromise the overall taste or texture. To add a pop of color and extra nutrition, I even squeezed in some corn. While I haven’t tasted the original, I can confidently say that my ONE yellow Mexican Lasagna version was an absolute triumph. It was the perfect, satisfying meal after shoveling over 30 inches of snow from the driveway – a true testament to healthy comfort food!

  • Customizable: Easily adapt the ingredients to suit your family’s preferences or whatever you have on hand, from different proteins to varied vegetables and spice levels.

Ingredients for Mexican Lasagna: Building Layers of Flavor

Crafting the perfect Mexican Lasagna involves a thoughtful selection of fresh, flavorful ingredients. Each component plays a crucial role in achieving that irresistible balance of taste and texture. Here’s a closer look at what you’ll need and why:

  • Bell Peppers – I often opt for green bell peppers because my daughter prefers them, but don’t hesitate to use a mix of green and red, orange, or yellow peppers. They add vibrant color, a hint of sweetness, and essential nutrients like Vitamin C. Dicing them uniformly ensures even cooking and distribution throughout the lasagna.
  • Onion – Either white or yellow onion will work beautifully here. Onions provide a foundational aromatic flavor that complements the other Mexican-inspired ingredients. Finely dicing them helps them blend seamlessly into the meat mixture.
  • Lean Ground Sirloin or Regular Lean Ground Beef – Choosing lean ground sirloin keeps the fat content down, which is important for the 21 Day Fix. However, feel free to use your preferred lean ground protein. Ground turkey is an excellent, lighter alternative, and shredded chicken (rotisserie chicken works great for a shortcut!) is absolutely delicious in this dish. For a vegetarian option, cooked lentils or black beans can be substituted.
  • Taco Seasoning – A good taco seasoning is key to authentic Mexican flavor. I highly recommend checking out my Salt Free Taco Seasoning recipe. It allows you to control the sodium content and avoid artificial ingredients often found in store-bought mixes, making your lasagna even healthier.
  • Shredded Cheddar Cheese – The cheese is what gives this lasagna its gooey, comforting appeal. Monterey Jack or a good Mexican blend are fantastic alternatives that melt beautifully and offer a slightly different flavor profile. For an even lighter option, consider a reduced-fat cheddar.
  • Refried Beans – The refried beans are crucial for both taste and texture, providing a creamy, savory layer that really completes the recipe. When buying, look for low-sodium or fat-free options to keep it healthier. You can also make your own from scratch using canned pinto beans for ultimate control.
  • Corn – Fresh, frozen, or canned (drained) corn works well. It adds a lovely sweetness, vibrant color, and an interesting texture contrast to the dish. It’s an easy way to sneak in extra vegetables!
  • Diced Tomatoes with Green Chilis – AKA Rotel – I absolutely love the convenient blend of diced tomatoes and green chilis in Rotel. You can choose mild or hot depending on your preference for spice. Be aware that the original Rotel has a definite kick, so if you’re sensitive to heat, definitely opt for the mild version. If Rotel isn’t available, simply use a can of diced tomatoes and add a small can of diced green chilis.
  • Olive Oil Cooking Spray – A light coating of olive oil cooking spray prevents sticking and helps crisp the tortillas slightly without adding excess fat. Any light oil spray you have on hand will work just fine.
  • Gluten-Free Corn Tortillas – Corn tortillas are naturally gluten-free and provide a great authentic flavor and structure to the lasagna. If gluten isn’t a concern, you can certainly use flour tortillas; just be sure to cut them in half to get approximately 16 pieces total for layering, similar to the corn tortillas. Cutting them helps them fit into the baking dish and creates more distinct layers.
  • Optional Toppings – These toppings elevate the dish and add fresh, vibrant flavors: cilantro, diced avocado (counts as your blue container!), diced jalapeno for extra heat, and a creamy cilantro lime yogurt sauce (made with Greek yogurt for extra protein).

Choosing Your Protein

The choice of protein is flexible and can greatly impact the overall flavor and nutritional profile of your Mexican Lasagna. Lean ground sirloin is a fantastic option for a classic taste with less fat. If you prefer poultry, ground turkey or shredded chicken are excellent, lighter alternatives. Shredded chicken, especially from a rotisserie chicken, can also be a wonderful time-saver, adding a different texture. For those looking for a plant-based version, consider using cooked black beans, pinto beans, or even lentils seasoned with taco seasoning. These options provide ample protein and fiber while keeping the dish vegetarian or vegan-friendly.

Perfecting Your Cheese and Beans

Cheese is a non-negotiable for most lasagnas, and our Mexican Lasagna is no exception. While shredded cheddar is a classic, Monterey Jack or a fiery Mexican blend can add a wonderful kick. For health-conscious eaters, reduced-fat cheese options melt just as well and cut down on calories. Refried beans provide a creamy, essential layer. If you’re not a fan of their traditional texture, black beans or pinto beans (mashed or whole) can be a great substitute, offering a similar earthiness with a different consistency. Always look for low-sodium versions of canned beans or prepare them from scratch for optimal health benefits.

Spice Level and Freshness

The beauty of this Mexican Lasagna recipe lies in its adaptability, especially when it comes to spice. The mild Rotel ensures a family-friendly heat level, but if you love a kick, opt for the regular or hot variety. Fresh diced jalapenos as a topping are perfect for those who want an extra zing. And don’t forget the fresh herbs! Cilantro brightens up the entire dish, and a squeeze of lime before serving adds a zesty finish that truly awakens the flavors. These fresh elements are simple additions that make a big impact.

Mexican lasagna with fresh toppings

I also kept the cheese and refried beans to less than a full blue container portion, leaving room for essential toppings like diced avocado. Trust me, a generous serving of fresh avocado is a game-changer! And a sprinkle of fresh cilantro, a few slices of diced jalapeno, and a dollop of creamy cilantro lime Greek yogurt sauce (for added protein and tang) definitely don’t hurt either. These fresh additions elevate the entire dish to a new level of deliciousness.

Can Mexican Lasagna Be Frozen? Meal Prep Made Easy

Absolutely, this Mexican Lasagna is incredibly freezer-friendly, making it a dream for meal prep! You have two main options for freezing: before or after baking.

  • Freezing Leftovers (After Baking): Once your lasagna has completely cooled, slice it into individual portions if you desire. Store these portions or the entire remaining casserole in an airtight, freezer-safe container. It will keep well for up to 2 months. To reheat, simply thaw in the refrigerator overnight and then warm in the oven or microwave until heated through.
  • Freezing Before Baking (For Future Meals): Assemble the lasagna as you normally would, ensuring all cooked components (meat, vegetables) have cooled completely before layering. However, skip adding the shredded cheese at this stage. Cover the assembled, unbaked lasagna tightly with plastic wrap and then aluminum foil. Store in a freezer-safe dish for up to 2 months. When you’re ready to enjoy it, thaw the lasagna completely in the refrigerator for 24-48 hours. Once thawed, add the shredded cheese and bake according to the recipe directions. You may need to add an extra 10-15 minutes to the baking time to ensure it’s piping hot in the center.
  • Regular Storage of Leftovers: For shorter-term storage, simply place any cooled leftovers in an airtight container and store in the refrigerator for up to 3 days. This ensures freshness and makes for quick meals during the week.

Are There Variations to This Recipe? Endless Possibilities!

Yes, absolutely! This Mexican Lasagna recipe is incredibly versatile and can be easily adapted to suit your tastes or what you have on hand. Don’t be afraid to get creative in the kitchen:

  • Protein Swaps: As mentioned, shredded chicken (especially from a rotisserie chicken for speed) or ground turkey are fantastic alternatives to ground beef. For a vegetarian option, you can double up on beans (black or pinto), or add cooked lentils for a hearty, plant-based filling.
  • Bean Alternatives: If refried beans aren’t your favorite (I get it, they can be an acquired taste for some!), black beans or pinto beans are excellent substitutions. You can mash them slightly for a creamier texture or leave them whole for more bite.
  • Add More Veggies: Boost the nutritional content by incorporating other finely diced vegetables. Zucchini, spinach (wilt it first!), or even finely chopped mushrooms can blend seamlessly into the meat mixture.
  • Spice it Up (or Down): Adjust the heat level to your preference. Use a mild Rotel for a gentler flavor, or opt for a “hot” Rotel if you love spice. A pinch of cayenne pepper or a dash of hot sauce can also be added to the meat mixture.
  • Cheese Choices: Experiment with different cheeses! A Colby Jack blend, Pepper Jack for extra heat, or even a sprinkle of cotija cheese on top after baking can add new dimensions of flavor.
  • Tortilla Types: While corn tortillas provide a great gluten-free option, flour tortillas can also be used if gluten isn’t a concern. Just be sure to cut them to fit your pan.

Meal Prep and Storage Tips for Busy Weeks

One of the greatest advantages of this 21 Day Fix Mexican Lasagna is its meal prep potential. Planning ahead can save you valuable time and keep you on track with your healthy eating goals. Here are some advanced tips:

  • Component Prep: You can prepare the meat and vegetable mixture a day or two in advance. Cook the ground beef (or other protein) with the onions, peppers, corn, and Rotel, then let it cool completely before storing it in an airtight container in the fridge. This way, assembly on baking day is super quick.
  • Portion Control: For easy container counting and reheating, consider baking the lasagna in smaller individual oven-safe dishes or cutting it into exact servings after baking. This makes grab-and-go meals a breeze.
  • Freezer Inventory: If you plan to freeze multiple batches, label your containers clearly with the date and cooking instructions. This prevents guesswork later on.
  • Thawing Best Practices: Always thaw frozen lasagna in the refrigerator, not at room temperature, to ensure food safety. Large casseroles may take up to 24-48 hours to thaw completely.
  • Reheating: For best results, reheat thawed lasagna in the oven at 350°F (175°C) until heated through and the cheese is bubbly again. For individual portions, the microwave works well, though the edges might not be as crispy.

Serving Suggestions: Completing Your Mexican Feast

While this Mexican Lasagna is a complete meal on its own, pairing it with a few simple sides can elevate your dining experience and add even more nutrients. Here are some serving suggestions:

  • Fresh Green Salad: A crisp side salad with a light vinaigrette offers a refreshing contrast to the rich flavors of the lasagna.
  • Cauliflower Rice: For an extra veggie boost and to keep things light, serve alongside a portion of seasoned cauliflower rice.
  • Extra Toppings Bar: Set up a “topping bar” with extra cilantro, avocado, Greek yogurt, salsa, and a squeeze of lime. This allows everyone to customize their plate and adds a fun, interactive element to dinner.
  • Roasted Vegetables: A side of roasted zucchini, bell peppers, or asparagus can complement the flavors beautifully and increase your vegetable intake.
  • Corn Salsa: A fresh corn salsa (without added sugar) can provide another layer of texture and sweetness.

21 Day Fix Nutrition Breakdown: Smart Choices for a Healthy Lifestyle

For those following the 21 Day Fix program, understanding your container counts is paramount. This re-engineered Mexican Lasagna recipe is designed to fit your plan while providing balanced nutrition:

  • Yellow Container (Carbohydrates): With careful adjustments to the tortillas and refried beans, this recipe ensures only 1 Yellow container per serving. This makes it a great choice for satisfying carb cravings without overdoing it.
  • Green Container (Vegetables): Packed with bell peppers, onions, and corn, each serving provides 1 Green container, ensuring you get a good dose of essential vitamins and fiber.
  • Red Container (Protein): The lean ground sirloin (or chosen protein) contributes 1 Red container per serving, offering a substantial amount of protein to keep you feeling full and support muscle health.
  • Blue Container (Healthy Fats/Cheese): The shredded cheese contributes 2/3 of a Blue container. This leaves room to add fresh, diced avocado (which would complete your 1 Blue container) as an optional topping, adding healthy fats and a creamy texture.

This thoughtful balance of containers ensures you’re getting a well-rounded, satisfying meal that aligns perfectly with the 21 Day Fix principles. It’s a testament that healthy eating doesn’t mean sacrificing flavor or feeling deprived.

Frequently Asked Questions About Mexican Lasagna

Here are some common questions you might have about making and enjoying this delicious 21 Day Fix Mexican Lasagna:

  • Can I make this vegetarian? Yes! Replace the lean ground sirloin with an equal amount of cooked black beans or pinto beans (or a mix), or seasoned cooked lentils. You could also use a plant-based ground meat substitute.
  • How spicy is this recipe? The recipe calls for mild Rotel, which gives it a very gentle, family-friendly flavor. If you prefer more heat, you can use regular or hot Rotel, or add a pinch of cayenne pepper to the meat mixture. Fresh diced jalapenos are also a great way to add heat as a topping.
  • Can I prepare this ahead of time? Absolutely! You can assemble the entire lasagna (without the cheese) and refrigerate it for up to 24 hours before baking. Just add the cheese before baking. This makes it perfect for busy weeknights or entertaining.
  • What if I don’t have olive oil cooking spray? Any light cooking oil spray will work, or you can brush a thin layer of olive oil directly onto the pan and tortillas.
  • Are there other vegetables I can add? Definitely! Finely chopped zucchini, bell peppers of different colors, or even spinach (wilted and squeezed dry) can be mixed into the meat layer for extra nutrients.
  • How long do leftovers last? Cooked and refrigerated lasagna will last for up to 3 days in an airtight container. If frozen, it’s good for up to 2 months.

Prep Time 15 minutes
Cook Time 30 minutes
Total Time 45 minutes

Ingredients

  • 2 bell peppers
  • 1 medium onion
  • 1 1/2 lb lean ground sirloin beef, or other ground protein
  • 2 tablespoons salt free taco seasoning
  • 1 1/3 cups shredded cheddar cheese
  • 3/4 cup refried beans
  • 1/4 cup corn
  • 10 oz mild Rotel (diced tomatoes with green chilis)
  • Olive oil cooking spray
  • 8 gluten free corn tortillas cut in half

Optional toppings

  • Cilantro
  • Sliced avocado or guacamole
  • Diced jalapeno
  • Lime
  • Greek yogurt

Instructions

  • Preheat oven to 375 degrees F (190°C).
  • Dice the bell peppers and onion. Heat olive oil cooking spray in a large skillet over medium heat. Add the diced peppers and onions and cook for 5-7 minutes, or until tender. Remove the cooked vegetables from the skillet and set aside in a bowl.
  • In the same skillet, brown your lean ground meat (sirloin, turkey, or chicken) over medium-high heat, breaking it up with a spoon, until fully cooked through and no pink remains. Drain any excess fat. Stir in the Rotel (diced tomatoes with green chilis), the cooked onions and peppers, corn, and taco seasoning. Allow the mixture to simmer for a few minutes, letting the flavors meld together.
  • Lightly spray the bottom of a 9×13 inch baking pan with olive oil cooking spray. Arrange 8 tortilla halves in a single layer at the bottom of the pan to form the first “noodle” layer of your lasagna. Lightly spray the tortillas with a bit more cooking spray. Evenly spread half of the refried beans over the tortillas, then layer half of the seasoned meat and vegetable mixture on top of the beans.
  • Repeat the layering process: place the remaining 8 tortilla halves on top of the meat mixture, followed by the rest of the refried beans and the remaining meat and vegetable mixture.
  • Sprinkle the shredded cheddar cheese evenly over the top layer of the lasagna.
  • Bake in the preheated oven at 375 degrees F (190°C) for 30 minutes, or until the lasagna is heated through, the cheese is completely melted, golden, and bubbly.
  • Remove from the oven and let it rest for 5-10 minutes before slicing. Serve hot, topped with your optional favorites: fresh diced jalapeños, a generous sprinkle of fresh cilantro, creamy avocado slices or guacamole, a dollop of Greek yogurt, and a squeeze of fresh lime juice. Enjoy your delicious and healthy Mexican Lasagna!
