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. Add minced garlic for an additional minute until fragrant.
Step 3: Add Seasoning and Tomatoes
Stir in taco seasoning mix. Cook for 1 minute before adding diced tomatoes with green chilies (including juice). Stir to combine, then 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. Place a layer of tortilla strips over the salsa. Spread half of the beef mixture over tortillas. Add half of black beans and corn. Repeat layers one more time. Top with remaining tortilla strips and pour remaining salsa over everything.
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
