Ingredients
For the Casserole Base
- 1 lb (450g) ground beef
- 1 small onion (diced)
- 2 cloves garlic (minced)
- 1 packet (1 oz) taco seasoning mix
- 1 can (14.5 oz) diced tomatoes with green chilies (Rotel)
For Layering
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (15 oz) corn, drained
- 1 cup salsa
- 6 small flour or corn tortillas (cut into strips)
Toppings
- 1 cup shredded Mexican cheese blend
- Fresh cilantro (chopped for garnish)
- Sour cream (for serving)
- Sliced jalapeños (optional, for serving)
- Diced avocado (optional, for serving)
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 to keep your casserole from being greasy.
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 diced tomatoes with green chilies (including juice), stirring to combine. Remove from heat once well mixed.
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 tortilla strips over this layer followed by half of the beef mixture. Add half of both black beans and corn before another layer of tortilla strips. Repeat with remaining beef mixture, black beans, corn, topping off with tortilla strips again. 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 until heated through.
Step 6: Add Cheese
About 15 minutes before serving, sprinkle shredded Mexican cheese blend on top of the casserole. Cover again so cheese can melt perfectly.
Step 7: Serve
Garnish with chopped fresh cilantro right before serving. Offer sour cream, sliced jalapeños, and diced avocado as optional toppings to enhance flavor!

- Skipping the Browning Step: Failing to brown the ground beef first can result in a greasy texture. Always cook and drain the beef before adding it to the slow cooker.
- Overcrowding the Ingredients: Adding too many layers or ingredients might prevent even cooking. Stick to the recommended layering for best results.
- Neglecting Seasoning Balance: Not adjusting the taco seasoning may lead to bland flavors. Taste and adjust as you go for optimal seasoning.
- Forgetting Cheese Timing: Adding cheese too early can cause it to become rubbery. Wait until the last 15 minutes of cooking to sprinkle it on top.
- Using Old Tortillas: Stale tortillas may not hold their shape well. Use fresh tortillas for better texture in your casserole.
