Ingredients
- 1 lb ground beef
- 1 tablespoon olive oil
- 1 small onion, diced
- 2 cloves garlic, minced
- 1 packet taco seasoning
- 1/2 cup water
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) corn, drained
- 1 can (10 oz) red enchilada sauce
- 1 cup salsa
- 6 corn tortillas, cut into strips
- 2 cups shredded Mexican blend cheese
- 1 cup shredded cheddar cheese
- 1/2 cup sour cream
- 1/4 cup chopped fresh cilantro
Step-by-Step Instructions
- Sauté Aromatics and Beef: Heat the olive oil in a skillet over medium heat. Add the diced onion and cook until softened, around 3 to 4 minutes. Stir in the minced garlic, then add the ground beef. Cook until the beef is thoroughly browned, breaking it up with a spoon as it cooks. Once browned, drain off any excess fat.
- Season the Beef: Sprinkle the taco seasoning over the browned beef mixture. Pour in 1/2 cup water and stir well to combine. Let it simmer for 5 minutes, allowing the flavors to meld and the liquid to reduce slightly.
- Prepare the Slow Cooker: Spread a thin layer of the red enchilada sauce evenly across the bottom of your slow cooker. This prevents sticking and adds flavor to the base layer.
- Layer the Casserole: Start by adding a layer of tortilla strips over the sauce. Next, add a layer of the seasoned beef mixture, followed by black beans, corn, and a generous spoonful of salsa. Sprinkle a combination of shredded Mexican blend and cheddar cheeses over this. Repeat these layers until all ingredients are used, finishing with a thick layer of cheese on top.
- Cook the Casserole: Cover the slow cooker and cook on LOW for 4 to 6 hours, or on HIGH for 2 to 3 hours. The casserole is ready when it is bubbly and the cheese has melted thoroughly.
- Rest and Serve: Once cooked, allow the casserole to sit for 5 to 10 minutes. This helps it set and makes serving easier. Top with sour cream and sprinkle chopped fresh cilantro on top before serving for added creaminess and freshness.
Pro Tips for Perfect Results
- Drain and Rinse Beans: Rinsing canned black beans removes excess sodium and improves texture.
- Use Fresh Ingredients: Fresh garlic and onion elevate the flavor considerably over dried versions.
- Don’t Skip Resting: Allowing the casserole to rest before serving ensures cleaner slices and enhances texture.
- Cheese Mix: Mexican blend cheese combined with sharp cheddar provides a balanced cheesy taste and gooey texture.
- Layer Evenly: Distributing ingredients uniformly ensures every serving tastes perfectly balanced between beef, beans, veggies, and cheese.
Variations and Substitutions
- Healthier Swaps: Use lean ground beef or substitute with ground turkey or chicken for a lighter option. Swap full-fat sour cream for Greek yogurt to reduce calories and add protein.
- Vegetarian Version: Replace beef with extra black beans, diced bell peppers, mushrooms, and zucchini for a hearty meatless casserole.
- Cheese Varieties: Experiment with pepper jack for a spicy kick or Monterey Jack for milder creaminess.
- Gluten-Free: Ensure the taco seasoning and enchilada sauce are gluten-free; corn tortillas are naturally gluten-free.
- Spice It Up: Add chopped jalapeños or hot sauce to the salsa layer if you like a spicier dish.
Storage and Reheating Tips
Store leftover enchilada casserole in an airtight container in the refrigerator for up to 3-4 days. When ready to eat, reheat individual portions in the microwave for 1-2 minutes or until warmed through. For quicker family meals, you can also freeze portions in freezer-safe containers for up to 2 months. Thaw overnight in the refrigerator before reheating in the microwave or oven. To reheat in the oven, place the casserole in a baking dish and cover loosely with foil, baking at 350°F (175°C) for about 20 minutes until hot and bubbly.
