Step-by-Step : How To Make Slow Cooker Taco Casserole

1. Brown the Ground Beef
In a large skillet over medium-high heat, cook the beef until browned. Drain off any extra fat—your casserole will thank you later.

2. Sauté Onions and Garlic
Add diced onion to the beef and cook until softened, about 3–4 minutes. Stir in the minced garlic and cook for another minute until your kitchen smells like taco night.

3. Add Seasoning and Tomatoes
Sprinkle in the taco seasoning and stir for 1 minute. Add diced tomatoes (juices included) and mix well. Remove from heat.

4. Layer It Up in the Slow Cooker

• Spray your slow cooker with non-stick spray.
• Spread a thin layer of salsa on the bottom.
• Add a layer of tortilla strips.
• Spread half the beef mixture on top.
• Add half the beans and corn.
• Repeat the layers, ending with tortilla strips and the rest of the salsa.

5. Let It Cook
Cover and cook on low for 4–5 hours or high for 2–3 hours.

6. Add the Cheese
About 15 minutes before serving, sprinkle the shredded cheese over the top. Cover again and let it melt into cheesy bliss.

7. Serve & Garnish
Scoop into bowls and top with fresh cilantro, sour cream, jalapeños, or avocado slices.

Cooking Tips for the Best Taco Casserole

• Want it spicier? Use hot salsa or add extra diced jalapeños between the layers.
• Feeding a crowd? Double the recipe and use a larger slow cooker.
• Tortilla texture tip: Flour tortillas get softer, while corn tortillas hold up a little better—choose based on your preference.
