Ingredients

Scale

Meat and Seasoning

  • 1 lb lean ground beef (80/20)
  • 1 packet taco seasoning (or 2 tbsp homemade taco seasoning)

Vegetables and 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: In a skillet over medium heat, cook the ground beef until it is fully browned and no longer pink, breaking it up as it cooks. Drain any excess fat from the skillet.
  2. Season the meat: Stir in taco seasoning and cook for an additional minute to let the spices bloom and coat the meat evenly.
  3. Combine ingredients in slow cooker: Transfer the seasoned ground beef to a slow cooker. Add rinsed black beans, corn kernels, diced tomatoes, and chopped bell peppers. Stir well to combine all ingredients thoroughly.
  4. Cook the casserole: Cover the slow cooker and cook on low heat for 4 hours or on high heat for 2 hours until the vegetables are tender and flavors have melded together.
  5. Add cheese and melt: About 15 minutes before serving, sprinkle the shredded cheddar cheese evenly over the top of the casserole. Cover the slow cooker again and allow the cheese to melt completely.
  6. Serve: Serve the taco casserole hot, optionally topped with sour cream, fresh cilantro, or other favorite toppings.
