A quick and comforting casserole that combines seasoned ground beef, creamy cheese sauce, and crispy Fritos for a fun twist on classic walking tacos.

Ingredients

Scale
  • 1 lb ground beef (or ground turkey for a leaner option)
  • 1 packet (1 oz) taco seasoning mix (store-bought or homemade)
  • 1/2 cup water
  • 1 small onion, finely chopped
  • 2 cloves garlic, minced
  • 2 cups shredded cheddar cheese
  • 1 cup milk (whole or 2%)
  • 2 tbsp unsalted butter
  • 2 tbsp all-purpose flour (can swap with gluten-free flour blend)
  • 1/2 tsp smoked paprika (optional)
  • 3 cups Fritos corn chips
  • Fresh cilantro, chopped (optional for garnish)
  • 1/2 cup sour cream or Greek yogurt (for serving)
  • 1 medium tomato, diced (optional for topping)
  • 1 jalapeño, thinly sliced (optional for heat)

Instructions

  1. Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish lightly with butter or non-stick spray.
  2. Heat a large skillet over medium-high heat. Add ground beef and break apart with a spatula. When it starts to brown (about 5 minutes), add chopped onion and garlic. Cook until onions are translucent, about 3 minutes.
  3. Sprinkle taco seasoning over the beef mixture. Pour in 1/2 cup water and stir well. Reduce heat to medium-low and simmer until sauce thickens slightly, about 5 minutes. Adjust seasoning if needed. Set aside.
  4. In a medium saucepan, melt butter over medium heat. Whisk in flour and cook for 1-2 minutes to form a roux, without browning.
  5. Slowly whisk in milk, stirring constantly to avoid lumps. Continue cooking and stirring until sauce thickens, about 5 minutes.
  6. Remove from heat and stir in shredded cheddar cheese and smoked paprika until smooth and melted. Season with salt and pepper.
  7. Spread half of the cooked beef mixture evenly in the baking dish. Pour half of the cheese sauce over it. Repeat with remaining beef and cheese sauce.
  8. Scatter Fritos evenly over the casserole.
  9. Bake uncovered for 15–20 minutes until cheese is bubbly and Fritos start to turn golden. Watch closely to prevent burning.
  10. Remove from oven and let rest for 5 minutes. Garnish with cilantro, diced tomato, and jalapeño slices if using.
  11. Serve warm with a dollop of sour cream or Greek yogurt.

Notes

Do not add Fritos until just before baking to keep them crispy. Watch the Fritos closely during baking to prevent burning. You can assemble the casserole ahead and refrigerate; add Fritos topping before baking. For gluten-free, use gluten-free flour and seasoning. Protein and cheese can be swapped to suit dietary preferences.
