Crockpot Mexican Casserole

This crockpot Mexican casserole with ground beef and tortillas is a perfect blend of all of the favorite Mexican flavors for a Taco Tuesday or weeknight meal for the whole family.

I love comfort food and this slow cooker casserole can fill you up and make delicious leftovers for the next day. My tip to make it taste just like a taco in a casserole dish is to add red enchilada sauce,

Ingredients Notes

Find the full list of the ingredients, exact quantities, and steps at the bottom of the page, on the printable recipe card.

• Ground beef. Use lean ground beef like 80%.
• Onion – a base for aromas and flavors. You can use yellow or white onion.
• Red enchilada sauce – it is like a Mexican hot sauce, rather spicy. Check the labels to make sure there are no added sugars and artificial flavor enhancers.
• Tomatoes with green chiles, canned diced tomatoes, and diced green chiles will be great but don’t forget to drain them.
• Black beans or pinto beans
• Corn. Amazing sweet veggies to add juicy flavor to the dish. It is fine to use canned or frozen corn. If using canned corn kernels, make sure to drain them or the casserole will get watery.
• Minced garlic. For best results don’t use garlic powder, but it can be an option in a pinch.
• Taco seasoning. Use store-bought or homemade taco seasoning. I don’t add extra salt as taco seasoning often contains salt already.
• Corn tortillas, cut into wedges. If you can’t find them, flour tortillas are ok to use.
• Shredded cheddar cheese. I always recommend buying cheese in blocks and shredding or grating at home. Using grated cheese is a good option too.

For Garnish

• Avocado
• Roma tomatoes
• Freshly chopped cilantro (or chopped green onion or parsley if you don’t eat cilantro)

Kitchen Equipment

• Slow cooker

What To Serve With Mexican Casserole

Cooked crock pot taco casserole pairs well with cooked rice, white or brown rice, cauliflower rice, or quinoa.

A side of salad is great for a lighter lunch.

Storage

Store leftover Mexican casserole in an airtight container in the fridge for 4-5 days. Reheat in the oven at 350F in a baking dish.

You can also freeze cooled casserole for up to 3 months. Thaw overnight in the fridge and reheat in the oven.

You can make the ground beef a day ahead.

Substitutions & Variations

• Meat options. You can use a leaner meat mixture like ground turkey, shredded chicken, or ground chicken.
• Add bell peppers and zucchini to bulk up the meal.
• Different cheese. Try Colby, Mexican blend cheese, or different Cheddar cheese varieties.
• Swap red enchilada sauce with green enchilada sauce or salsa verde if you want milder heat.
• Make it in the oven. Load all the ingredients in a 9×13 casserole dish and bake at 350F for 45 minutes.
• Not enough heat? Add chili powder, and cayenne pepper, and use sharp cheddar.
• Use your favorite toppings. Sour cream or plain yogurt will be a nice addition too, just like lime juice or wedges, black olives, pickled onions, and sliced jalapenos.
• Slow cooker Mexican Lasagna. Use corn tortillas as lasagna sheets and layer the meat mixture in between. This version won’t last as long as tortillas will become mushy over the next few days.
• Different ways to change it up: use rotel tomatoes, vegetable broth, Mexican cheese blend, sweet potatoes, layers of corn tortillas, melted cheese, or green chilies.
