Ingredients
  

  • 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)
  • 1 can 15 oz black beans, drained and rinsed
  • 1 can 15 oz corn, drained
  • 1 cup salsa
  • 1 cup shredded Mexican cheese blend
  • 6 small flour or corn tortillas cut into strips
  • Fresh cilantro chopped (for garnish)
  • Sour cream for serving
  • Sliced jalapeños optional, for serving
  • Diced avocado optional, for serving

Instructions
 

  • Brown the Ground Beef:
    In a large skillet over medium-high heat, cook the ground beef until browned. Drain any excess fat.
  • Sauté Onions and Garlic:
    Add the diced onion to the skillet with the beef and cook until softened, about 3-4 minutes.
    Add the minced garlic and cook for an additional 1 minute until fragrant.
  • Add Seasoning and Tomatoes:
    Stir in the taco seasoning mix and cook for 1 minute.
    Add the diced tomatoes with green chilies (including the juice) and stir to combine. Remove from heat.
  • 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 of the slow cooker.
    Place a layer of tortilla strips over the salsa.
    Spread half of the beef mixture over the tortillas.
    Add half of the black beans and half of the corn.
    Add another layer of tortilla strips, followed by the remaining beef mixture, black beans, and corn.
    Top with the remaining tortilla strips and pour the remaining salsa over the top.
  • Cook the Casserole:
    Cover and cook on low for 4-5 hours or on high for 2-3 hours.
  • Add Cheese:
    About 15 minutes before serving, sprinkle the shredded Mexican cheese blend over the top of the casserole. Cover and let the cheese melt.
  • Serve:
    Garnish with chopped fresh cilantro.
    Serve with sour cream, sliced jalapeños, and diced avocado, if desired.
