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 the 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 the 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 the tortillas. Add half of the black beans and half of the corn. Add another layer of tortilla strips followed by the remaining beef mixture, black beans, and corn. Top with remaining tortilla strips and pour any 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
About 15 minutes before serving, sprinkle shredded Mexican cheese blend over the top of the casserole. Cover again to let cheese melt.

Common Mistakes to Avoid
When making your Slow Cooker Taco Casserole, it’s easy to overlook some key steps. Here are common mistakes to avoid for the best results.
- Skipping the browning step: Failing to brown the ground beef can lead to less flavor in your casserole. Always brown the meat first for a richer taste.
- Not draining canned beans and corn: Leaving excess liquid in your cans can make your casserole too watery. Drain and rinse black beans and corn before adding them.
- Overloading on toppings too soon: Adding cheese or toppings at the beginning of cooking can result in burnt or undesirable textures. Wait until the last 15 minutes to add cheese.
- Ignoring layering techniques: Skipping layers creates a mixed-up dish instead of distinct flavors. Layer ingredients thoughtfully for an even distribution of taste.
- Cooking on high too long: If you cook on high for too long, you risk drying out the casserole. Stick to recommended cooking times for moist results.
