step-by-step instructions

Prep the Oven and Pan: Preheat oven to 350 degrees F. Coat an 8x8x4-inch baking dish with nonstick spray.
Brown the Meat: Cook beef and onion in a large skillet over medium-high heat, breaking it up into small crumbles, until no pink remains, about 3 minutes. Season with a sprinkle of salt and pepper, add in the garlic, stir to incorporate. Pour off all the grease.
Mix the Filling: Return the skillet to heat and stir in the refried beans, enchilada sauce, tomatoes, jalapeños, and olives until combined.
Assemble the Layers: Spread a thin layer of the mixture into the bottom of the prepared baking dish. Cover with 2 tortillas, splitting one of them in half to fit. Spread more of the meat mixture on top, followed by 1/3 cup cheese. Repeat these layers 3 more times, ending with meat mixture and cheese.
Bake: Transfer to the oven and bake until cheese is bubbly and golden, about 25 minutes.
Rest: Let rest for 10 minutes before slicing, which will help the layers stay intact.
Serve: Serve with your choice of toppings and enjoy!

Protein Customization Options

Using Ground Turkey

Replace the lean ground beef with ground turkey for a leaner protein option. Brown the turkey exactly as you would the beef, ensuring it is cooked through before adding the vegetables and seasonings.

Substituting with Shredded Chicken

Cooked, shredded chicken is an excellent alternative to ground meat. Stir the shredded chicken into the bean and sauce mixture rather than browning it in a skillet first.

Plant-Based Meat Alternatives

Use a plant-based ground crumble to make this dish vegetarian-friendly. Sauté the crumbles with the onions and garlic using the same timing as the beef for a similar texture.

Lean Beef Percentages

Use 90% lean ground beef or higher to minimize the amount of grease that needs to be drained. This helps maintain the flavor profile without adding excess oil to the layers.

Bean and Cheese Modifications

Using Black Beans

If you prefer a chunkier texture, replace the refried beans with canned black beans. Ensure the black beans are rinsed and drained before stirring them into the meat mixture.

Substituting with Pinto Beans

Whole pinto beans offer a traditional flavor and a softer bite than black beans. Use them as a direct replacement for refried beans to change the consistency of the filling.

Adding Pepper Jack Cheese

For a spicier profile, swap the Mexican blend cheese for shredded Pepper Jack. This adds a sharp kick and a creamy melt that complements the jalapeños.

Using Sharp Cheddar

Sharp cheddar provides a bolder, saltier taste than a standard Mexican blend. Mix it with Monterey Jack to maintain a good melting point while increasing the flavor intensity.

Tortilla Variations

Using Flour Tortillas

Flour tortillas can be substituted for corn tortillas if you prefer a softer, more bread-like layer. Be aware that flour tortillas are denser and may require a slightly longer bake time to heat through.

Substituting with Tortilla Chips

Crushed corn tortilla chips can be used as a layer instead of whole tortillas. This creates a more textured, crunchy effect similar to a nachos casserole.

Softening Corn Tortillas

If your corn tortillas are stiff, warm them in a microwave for 15 seconds before layering. This prevents them from cracking when you split them to fit the baking dish.

Pairing and Serving Suggestions

Cilantro-Lime Rice

Serve a side of fluffy white rice tossed with fresh lime juice and chopped cilantro. The acidity of the lime cuts through the richness of the cheese and beans.

Mexican Street Corn (Esquites)

Pair the lasagna with Esquites, which consists of corn kernels mixed with mayo, lime, and cotija cheese. This provides a creamy and sweet contrast to the savory beef.

Fresh Avocado Salad

Create a simple side salad using diced avocado, red onion, and a lime vinaigrette. This adds a fresh, cool element to the plate that balances the heat of the jalapeños.

Breakfast Serving Ideas

This dish can be served for breakfast or brunch by topping individual slices with poached or scrambled eggs. The savory beef and beans make for a filling morning meal.

Storage and Preservation

Refrigerating Leftovers

Allow the casserole to cool completely before wrapping it in plastic wrap and aluminum foil. Store it in the refrigerator for up to 3 days to maintain freshness.

Freezing Baked Portions

Cut the baked lasagna into individual servings and wrap each piece tightly in foil. Store these in a freezer-safe bag for up to 2 months.

Freezing the Unbaked Casserole

Assemble the layers in a foil-lined dish and freeze until solid. Once frozen, lift the block out and store it separately to reuse the baking dish; thaw overnight in the fridge before baking.

Make-Ahead Assembly

Assemble the entire lasagna up to 24 hours before you plan to bake it. Keep it covered in the refrigerator and either let it reach room temperature or add 15 minutes to the baking time.

Reheating and Texture Tips

Oven Reheating Method

To maintain the best texture, reheat slices in the oven at 325 degrees F. Cover with foil to prevent the cheese from over-browning while the center heats through.

Microwave Reheating

For a quick reheat, microwave a slice on medium power for 1-2 minutes. Add a teaspoon of water to the plate to keep the tortillas from drying out.

Preventing Dry Edges

When reheating or baking, ensure the dish is tightly covered with foil until the last 5-10 minutes. This traps steam and keeps the tortillas moist.

Troubleshooting Common Issues

Preventing Sogginess

Ensure all canned ingredients, especially the tomatoes and olives, are thoroughly drained. Excess liquid in the filling can make the tortillas mushy during the baking process.

Fixing Dry Tortillas

If the edges of the tortillas look dry after baking, brush them lightly with a bit of melted butter or oil before they go into the oven. This helps them brown without hardening.

Achieving Clean Slices

The 10-minute resting period is critical for structural integrity. Cutting into the lasagna too early will cause the layers to slide and the filling to run.

Managing Cheese Browning

If the cheese is browning too quickly before the center is hot, lower the oven temperature by 25 degrees. This allows the heat to penetrate the layers more evenly.

Frequently Asked Questions

Can I use a 9×13 inch pan instead?

Yes, but you will need to increase the ingredients by 50% to maintain the height of the layers. Otherwise, the lasagna will be very thin and may overcook.

How do I make the dish spicier?

Increase the amount of diced jalapeños or add a teaspoon of cayenne pepper to the ground beef while browning. You can also use a “hot” variety of enchilada sauce.

Which brand of corn tortillas works best?

Use high-quality, thick corn tortillas found in the refrigerated section or authentic brands. Thin, store-brand tortillas may disintegrate more easily under the weight of the beef.

Can I omit the black olives?

Yes, the olives are optional. If you dislike them, you can replace them with diced green chiles for more flavor or simply leave them out.

What is the best enchilada sauce to use?

A red enchilada sauce provides the traditional flavor for this recipe. Ensure it is a smooth sauce rather than a chunky salsa to keep the layers cohesive.

How do I prevent the beef from sticking to the pan?

Ensure the baking dish is well-coated with nonstick spray. Using a ceramic or glass baking dish also helps the lasagna release more easily after resting.
