Why You’ll LOVE My Taco Lasagna Recipe
I got this recipe from the wife of a teacher colleague when I first started teaching, back in 2000. She brought it to a party and I immediately HAD to have the recipe. I’ve been making it ever since, and it’s my go-to meal to take to a friend in need.
It’s layered just like a traditional lasagna but instead of pasta you use corn tortillas like you would for enchiladas. Add some other favorite southwestern ingredients like seasoned ground beef, cheese, and green chiles and you end up with family-friendly dinner that’s easy to make.
It’s so much easier than making enchiladas or lasagna, too. No boiling pasta required and instead filling and rolling the tortillas you just layer everything in your baking dish. You still get all the great flavors but without all the work.
Ingredients in Mexican Lasagna Casserole
This Mexican Casserole uses one my favorite beef taco fillings – here’s what you need to make it:
Ground Beef: You can also substitute ground turkey. I’ve made it both ways.
Taco Seasoning: Use your favorite packet.
Canned Diced Tomatoes: I love using petite diced but either one works fine.
Tomato Sauce: The canned kind
Diced green Chiles: The kind that come in the can – add so much spice!
Corn Tortillas: You won’t miss the flour – the southwest lasagna wouldn’t be complete without them.
Monterey Jack Cheese: Can’t have lasagna without cheese!
How to make Taco Lasagna Casserole
- Cook the beef in a large skillet until its browned and then drain the excess fat. Add the taco seasoning, tomatoes, tomato sauce, and green chiles.
- Stir and bring it to a boil and then lower the heat. Simmer the filling for about five minutes.
- In a small bowl, combine ricotta cheese with the eggs.
- Cut your corn tortillas in half and shred your cheese. Drain a can of sliced olives.
- Spread half of the beef mixture in the bottom of a 9×13” baking dish. Place half of the tortillas in an even layer on top. Spread half of the ricotta over the top and the sprinkle half of the shredded cheese over the top.
- Repeat the layers again starting with the beef and then top the casserole with the rest of the shredded cheese and olives.
- Bake until the cheese is melted and the casserole is heated through.
We love this taco casserole just as it is hot from the oven, but sometimes we add some toppings like you would for enchiladas. Here are some ideas if you want to add some garnishes:
- Spoon your favorite salsa over the top.
- Add some sour cream.
- Sliced avocado, olives and green onions are great.
- Add a spoonful of guacamole.
- A sprinkling of chopped cilantro or parsley adds a nice pop of color.
Can I Make it Ahead?
Yes, you can make it ahead – it’s one of the things I love about this recipe. You can make the filling and assemble the casserole and then keep it in the refrigerator for up to a day in advance.
When you take it out of the fridge it will be cold so you will need to add five to ten minutes to the cooking time.
How Long Do the Leftovers Keep?
The leftovers keep well in the refrigerator for up to three days. I like to portion them out in single-serving containers so it’s easy to heat up for lunches.
You can also freeze the leftovers for up to a month and reheat in the microwave.
I’ve made this southwestern lasagna for weeknight dinners but it’s great when you have guests or need a dish for potluck. I hope you love it as much as we do!
