How to Make Slow Cooker Taco Casserole
Step 1: Brown the Ground Beef
In a large skillet over medium-high heat, cook the ground beef until browned. Drain any excess fat.
Step 2: Sauté Onions and Garlic
Add the diced onion to the skillet with the beef. Cook until softened, about 3-4 minutes. Then add minced garlic and cook for an additional minute until fragrant.
Step 3: Add Seasoning and Tomatoes
Stir in the taco seasoning mix and cook for 1 minute. Add the diced tomatoes with green chilies (including juice) and stir to combine. Remove from heat.
Step 4: Layer the Ingredients in the Slow Cooker
Spray the inside of your slow cooker with non-stick cooking spray. Spread a thin layer of salsa on the bottom of the slow cooker. Place a layer of tortilla strips over the salsa. Spread half of the beef mixture over tortillas, then add half of the black beans and half of the corn. Add another layer of tortilla strips followed by remaining beef mixture, black beans, and corn. Top with remaining tortilla strips and pour remaining salsa over top.
Step 5: Cook the Casserole
Cover and cook on low for 4-5 hours or on high for 2-3 hours.
Step 6: Add Cheese
About 15 minutes before serving, sprinkle shredded Mexican cheese blend over top of casserole. Cover to let cheese melt.
