This Frito Taco Casserole layers seasoned beef, gooey cheese, and crunchy Fritos for an easy weeknight dinner the whole family will devour.
Preheat the oven to 350 degrees F (175 degrees C) and lightly grease a 9x13 inch baking dish.
In a large skillet over medium heat, cook the ground beef and diced onion together, breaking up the meat, until the beef is browned and the onion is soft, about 6 to 8 minutes. Drain excess grease.
Stir in the taco seasoning and water. Simmer for 3 to 4 minutes until slightly thickened.
Stir in the refried beans, if using, and the diced tomatoes with green chiles until well combined. Remove from heat.
Spread half of the Fritos evenly across the bottom of the prepared baking dish.
Spoon the beef mixture evenly over the Fritos layer.
Dollop the sour cream over the beef mixture and gently spread it into an even layer.
Sprinkle 1 1/2 cups of cheddar cheese and all of the Monterey Jack cheese over the top.
Scatter the remaining Fritos over the cheese, then top with the remaining 1/2 cup of cheddar cheese.
Bake uncovered for 18 to 22 minutes, until the cheese is fully melted and bubbling around the edges.
Let the casserole rest for 5 minutes, then top with shredded lettuce, diced tomato, and green onions before serving.
Once baked, let the casserole rest for about five minutes before serving. This short rest allows the cheese to set slightly so your slices hold together instead of sliding apart. Top with shredded lettuce, diced tomato, and a sprinkle of green onion for freshness and color.
For leftovers, store any extra casserole in an airtight container in the fridge for up to three days. When reheating, a quick trip to the microwave works fine, though adding a small handful of fresh Fritos afterward will bring back that essential crunch.
Whether you are making this for a casual family dinner or bringing it to a potluck, this Frito taco casserole is guaranteed to disappear fast. It is hearty, it is fun to eat, and it turns pantry staples into something genuinely craveable. Once you try it, do not be surprised if it becomes a permanent fixture in your dinner rotation.
