Ingredients
  

Casserole
  • 1 lb lean ground beef
  • 1 medium onion diced
  • 2 cloves garlic minced
  • 1 packet taco seasoning about 1 ounce
  • 1/4 cup water
  • 1 cup salsa
  • 9 oz corn chips like Fritos, lightly crushed
  • 3 cups shredded cheddar cheese or a Mexican blend, divided
Optional Toppings
  • Shredded lettuce
  • Diced tomatoes
  • Sour cream
  • Sliced black olives

Equipment

  • 1 9x13 inch baking dish
  • 1 Large Skillet

Method
 

  1. Preheat your oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
  2. In a large skillet over medium-high heat, cook the ground beef and diced onion until the beef is browned. Drain off any excess grease.
  3. Stir in the minced garlic, taco seasoning packet, and water. Bring to a simmer and cook for 3-4 minutes, until the sauce has thickened slightly.
  4. Spread half of the crushed corn chips in the bottom of the prepared baking dish. Top with the beef mixture, spreading it into an even layer.
  5. Pour the salsa over the beef layer, then sprinkle with half of the shredded cheese (1.5 cups).
  6. Top with the remaining crushed corn chips and the remaining 1.5 cups of shredded cheese.
  7. Bake for 20-25 minutes, until the casserole is hot and bubbly and the cheese is fully melted.
  8. Let the casserole rest for 5-10 minutes before topping with lettuce, tomatoes, sour cream, and other desired toppings.

Notes

Storage: Store leftovers in an airtight container in the refrigerator for up to 4 days.
Make-Ahead: Assemble the casserole without the final layer of chips and cheese up to 24 hours in advance. Add the top layers just before baking.
Cheese Tip: For the best melt, shred your own cheese from a block.
