Instructions

  • Preheat the oven to 350°F (175°C).
  • Place a skillet or cast iron pan on the stove top over medium heat. Add 1.5 lbs (680 g) ground beef and 1 cup (150 g) yellow onion and cook for 6-8 minutes, breaking up the beef with a spatula as it cooks.
  • Cook until no more pink remains and the onions are translucent. If there is a lot of fat in the skillet, drain most of it with a spoon.
  • Add the 15 oz (425 g) can black beans, 1 cup (240 g) mild salsa, 1/2 cup (120 g) sour cream, and 2 tablespoons gluten-free taco seasoning. Stir to combine.
  • Let cook 2-3 minutes to let the sauce thicken.
  • If your skillet is not oven-safe, place the ground beef mixture into a greased 2 quart baking dish or 7x11-inch baking dish.
  • Top with 1 cups (113.52 g) shredded cheddar cheese. Sprinkle 2 cups (80 g) Frito corn chips on top of the cheese. Top with remaining 0.5 cups (56.48 g) shredded cheddar cheese.
  • Cover the casserole dish with foil and bake at 350°F (175°C) for 20-25 minutes, until the cheese is melted.
  • Top with your desired toppings before serving, like sour cream, shredded lettuce, sliced avocados, diced tomatoes, jalapeño, pickled onions, fresh cilantro, or black olives. I used 1 cup (55 g) shredded lettuce, 1/2 cup (90 g) diced tomato or halved cherry tomatoes, and 1/4 cup (5 g) cilantro.
  • Serve immediately.

Notes

  • Gluten-free: Fritos are labeled gluten-free, but always check your taco seasoning. Many store-bought packets contain gluten. Use my homemade gluten-free taco seasoning to be safe.
  • Protein swap: Ground turkey or chicken works in place of beef. Brown it the same way.
  • Make ahead: Assemble the casserole without the Fritos and refrigerate up to 24 hours. Add Fritos and cheese right before baking.
  • Leftovers: Store without Fritos if possible, they get soggy. Add fresh chips when reheating.
  • Nutrition: Calculated without optional toppings.
