Mexican Ground Meat Casserole is my go-to when I want big flavour without babysitting a stovetop. It comes together fast, feeds a group and tastes even better the next day. Think of it as the dinner that makes you look like you tried harder than you actually did.

Ingredients

  • Meat and Vegetables
  • 800–900g ground beef (80/20) or about 1.75–2 lb
  • 1 large onion, finely chopped
  • 2 cloves garlic, finely chopped
  • 1 to 2 bell peppers, chopped
  • 1 tablespoon olive oil (only if needed for sautéing)
  • Seasoning and Sauce
  • 2 to 3 tablespoons taco seasoning (or use 1 tbsp chili powder + 1 tsp ground cumin + ½ tsp smoked paprika + salt and pepper to taste)
  • 1 cup (240ml) salsa or 1 can (400g / 14 oz) diced tomatoes, well drained
  • Salt and pepper to taste
  • Mix-ins
  • 1 can black beans (400g / 14 oz), drained and rinsed
  • 1 can corn (300g / 10 oz), drained or 1 to 1½ cups frozen corn
  • Layers and Topping
  • Large handful of tortilla chips or about 8–10 corn tortillas lightly toasted in a dry pan
  • 3 to 4 cups (about 350–400g) shredded cheddar, Monterey Jack, or Mexican blend cheese
  • To Serve
  • Fresh coriander (cilantro)
  • Sour cream
  • Diced tomatoes, sliced jalapeños, or avocado (optional)

Instructions

  • Preheat the oven to 180°C / 350°F.
  • Warm a large pan over medium-high heat and brown the ground beef in batches so it browns rather than steams. Drain most of the grease, leaving just a little for flavour.
  • Add the onion, bell pepper, and garlic to the pan and cook until softened.
  • Stir in the taco seasoning. Add the salsa or drained tomatoes and let the mixture simmer a few minutes so it thickens slightly and is not watery.
  • Stir in the black beans and corn. Taste and adjust seasoning with salt and pepper.
  • Lightly grease a 9×13 inch (about 23×33 cm) baking dish.
  • Spread a thin layer of the beef mixture across the bottom. Add a layer of tortilla chips (or roughly torn toasted tortillas). Spread more of the beef mixture on top, then sprinkle a generous layer of cheese.
  • Repeat layers until all filling is used, finishing with a thick layer of cheese on top.
  • Cover with foil and bake for 20 to 25 minutes, until heated through.
  • Remove the foil and bake another 5 minutes to melt the cheese fully, or place under the grill (broiler) briefly to lightly brown the top.
  • Let the casserole rest 10 minutes before serving so it sets and slices neatly.
  • Top with fresh coriander and serve with sour cream and any extra toppings you like.
