Quick Weeknight Taco Casserole

Taco casserole is an easy weeknight meal made with ground beef that is a great make ahead meal for those busy nights with all the things going on in life.

I’m in a different place in life all of a sudden. I’ve got three kids in totally different stages of life and while it should be better because they all go to school every day (well, half day on the Kindergartner) it’s actually crazy busy. High schoolers have so, so much going on, but 6th grade is all about the projects and busy work with school plus budding social lives and then Kindergarten. Well, you all know the busy work of Kindergarten! 
I’ve been asking on instagram how I can help you get dinner on the table and the unanimous vote was for something with ground beef and that can be made ahead or frozen. Cue the taco casserole…

What Goes in Taco Casserole?
Think taco ingredients plus a few extra items for more flavor and layers! Here is what you will need with a little explanation of why it’s included:
Corn Tortillas: these give the casserole structure and flavor
Red Enchilada Sauce: keeps the tortillas nice and soft and adds so much flavor
Onion: flavor, flavor, flavor and some texture too
Red Bell Pepper: ditto
Garlic: flavor
Ground Beef: main source of protein and the real substance of the casserole, this can be swapped for ground turkey or chicken
Taco Seasoning: we love our homemade seasoning, but you can go with store bought too
Water: helps thicken the taco seasoning and keep the meat moist
Fire Roasted Tomatoes: flavor all day, a hint of smokiness and just the tiniest bit of heat
Refried Beans: another great source of protein and helps the meat stick together for the structure of the casserole
Colby Jack Cheese: all Mexican dishes should be topped with a layer of melted gooey cheese!
Monterey Jack Cheese: see above
Olives: flavor, texture
Red Onion: flavor, texture and a bright pop of color
Green Onion: that bright green color and fresh burst of flavor
Tomato: flavor, you could use fresh pico de gallo instead – yum!
Fritos: the crunch is all the texture you need!
The measurements for each ingredient can be found in the recipe card down below.

Steps to Making Taco Casserole
The best things about casseroles is that they are so easy to make and they make great leftovers! You can make them ahead of time and throw them in the oven when you’re ready to eat it or they make great freezer meals! They are just a win win all around. Here are the basic steps for making this casserole recipe:
Preheat oven.
Place the red enchilada sauce in a shallow dish and dip each side of the tortillas in it. Set them aside.
Grease a 9×13 baking dish.
Heat a few drizzles of olive oil in a large pan over medium heat then add the onions and bell peppers. Cook until tender.
Add the garlic and stir until fragrant. Push everything to one side and add the ground beef.
Brown the ground beef and break it up until small and cooked through. Drain the excess grease and add the taco seasoning, water, enchilada sauce and canned tomatoes.
Stir everything together and let simmer until the liquid has absorbed and the mixture thickens.
Place 4 of the tortillas on the bottom of the baking dish. Spread half the beans and half the meat on the tortillas.
Combine the cheeses in a small bowl and then sprinkle half the cheese.
Repeat the same layers one more time and then bake.
Remove from oven and add toppings. Serve!

All of these instructions can be found in full detail in the recipe card at the end of this post.

How to Make it Low Carb
I love that you don’t have to use the tortillas if you’re watching your carbs. Or you could totally throw in cauliflower rice to bulk it up.

You sure can! You could use ground turkey, ground chicken or even chorizo for your meat!
