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 before moving on to the next step.
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. Next, add the diced tomatoes with green chilies (including juice), stirring to combine. Remove from heat.
Step 4: Layer the Ingredients in the Slow Cooker
Spray your slow cooker’s interior with non-stick cooking spray. Start by spreading a thin layer of salsa on the bottom. Place a layer of tortilla strips over this salsa. Spread half of the beef mixture over the tortillas followed by half of both black beans and corn. Repeat with another layer of tortilla strips, remaining beef mixture, black beans, and corn. Top off with remaining tortilla strips and pour any leftover salsa over everything.
Step 5: Cook the Casserole
Cover your slow cooker 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 over the casserole top. Cover again to let cheese melt perfectly.
Step 7: Serve
Garnish with chopped fresh cilantro before serving hot. Enjoy with sour cream, sliced jalapeños, or diced avocado if desired!
