4.1 from 40 reviews

This Slow Cooker Taco Casserole combines seasoned ground beef, black beans, corn, diced tomatoes, and colorful bell peppers slow-cooked to perfection and topped with melted cheddar cheese for a deliciously hearty and easy meal ideal for busy weeknights.

Ingredients

Scale

Meat

  • 1 lb lean ground beef (80/20)

Seasoning

  • 1 packet taco seasoning (or 2 tbsp homemade)

Vegetables & Beans

  • 1 can (15 oz) black beans, rinsed
  • 1 cup corn kernels (fresh or frozen)
  • 1 can (14.5 oz) diced tomatoes
  • 1 cup chopped bell peppers (mix of colors)

Dairy

  • 1 cup shredded cheddar cheese

Instructions

  1. Brown the beef: Heat a skillet over medium heat and cook the ground beef until fully browned. Drain any excess fat to keep the casserole from being greasy.
  2. Add seasoning: Stir in the taco seasoning and cook for an additional minute to incorporate the flavors evenly into the beef.
  3. Combine ingredients in slow cooker: Transfer the cooked beef into the slow cooker. Add the rinsed black beans, corn kernels, diced tomatoes, and chopped bell peppers. Mix everything thoroughly to distribute the ingredients evenly.
  4. Slow cook the casserole: Cover the slow cooker and cook on low for 4 hours or on high for 2 hours. This allows all the ingredients to meld together and develop rich flavors.
  5. Add cheese topping: About 15 minutes before serving, sprinkle the shredded cheddar cheese evenly over the top. Cover again and let the cheese melt into a gooey, delicious layer.
  6. Serve: Dish out the casserole hot, and optionally top with sour cream, fresh cilantro, or any preferred taco toppings for added flavor and freshness.

Notes

  • You can substitute ground turkey or chicken for a leaner option.
  • For extra heat, add diced jalapeños or a dash of hot sauce before slow cooking.
  • Serve with tortilla chips or over a bed of rice for a complete meal.
  • Leftovers store well in the refrigerator for up to 3 days and can be reheated easily.
