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.

Add the diced onion to the skillet with the beef. Cook until softened, about 3–4 minutes. Add minced garlic and cook for an additional minute until fragrant.

Stir in the taco seasoning mix. Cook for one minute before adding diced tomatoes with green chilies, including their juice. Stir to combine and 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. Layer tortilla strips over salsa, followed by half of the beef mixture. Add half of black beans and corn. Repeat layers with remaining ingredients. Finish with leftover tortilla strips topped with remaining salsa.
