Ingredients Equipment Method Notes

Ingredients
  

  • 1 pound ground beef 80/20 blend
  • 1 large onion, chopped
  • 1 green bell pepper, chopped
  • 8-10 corn tortillas
  • 2 cups shredded cheddar cheese
  • 1 cup shredded Monterey Jack cheese
  • Optional toppings: sour cream, salsa, guacamole, chopped cilantro

Equipment

  • Slow cooker
  • large skillet
  • spatula
  • Measuring cups
  • Measuring spoons
  • knife
  • cutting board
  • Oven
  • baking sheet

Method
 

  1. Preheat oven to 350°F (175°C).
  2. Lightly bake corn tortillas on a baking sheet for 5 minutes per side to dry them out slightly.
  3. Brown the ground beef in a large skillet over medium-high heat. Drain off any excess grease.
  4. Add the chopped onion and bell pepper to the skillet and cook until softened, about 5 minutes.
  5. Stir in the taco seasoning, diced tomatoes, black beans, and corn. Bring to a simmer and cook for 5 minutes, stirring occasionally.
  6. Lightly grease the bottom of your slow cooker.
  7. Place 2-3 corn tortillas in the bottom of the slow cooker, overlapping as needed to cover the surface.
  8. Spread about one-third of the beef mixture over the tortillas.
  9. Sprinkle with one-third of the cheddar cheese and one-third of the Monterey Jack cheese.
  10. Repeat layers two more times, ending with a layer of cheese.
  11. Cover and cook on low for 3-4 hours, or until the cheese is melted and bubbly and the casserole is heated through. Cooking time may vary depending on your slow cooker.
  12. Let stand for 10-15 minutes before serving.
  13. Top with your favorite toppings and enjoy!

Notes

For a spicier kick, add a pinch of cayenne pepper to the beef mixture or use a spicier salsa. Freshly shredded cheese melts better than pre-shredded cheese. Store leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, microwave individual portions or bake in a preheated oven at 350°F until heated through.
