Preheat the oven to 350 degrees F and spray a 9X13 pan with a non stick cooking spray.
Brown 1 pound ground beef with ½ diced white onion in a large skillet over medium heat.
Stir in 2 teaspoons minced garlic and cook for 1 minute.
Add 2 tablespoons taco seasoning and 1 cup salsa to the skillet. Stir to combine. Simmer for 3-5 minutes.
Remove the skillet from the heat and stir in 1 cup sour cream and 1 cup shredded cheddar cheese.
Pour 1/2 of the meat mixture into the 9X13 pan, top with 1/3 (approximately 2/3 cups) of the shredded cheese and half of the crushed Doritos. Then repeat these layers again. You will have some shredded cheese remaining.
Cover the pan with foil and bake for 20 minutes. Remove the foil, top with the remaining shredded cheese and bake for 5-10 more minutes until the cheese is melted and slightly bubbly.

Notes
Some of our favorite toppings include diced tomatoes, lettuce, cilantro, jalapeños and diced avocado. Recipe Tips
Crushing the Doritos - When I make this casserole, I like to keep the Doritos in bigger pieces. This keeps them from getting to soggy and have that nice crunch.
Remove the Foil - We like our cheese to be golden brown on top. So we always remove the foil when there is about 5 to 10 minutes left.
Nachos Cheese Doritos - You can definitely use any type of chips you prefer. But we think it taste the best with the Nachos Cheese Doritos.
Use Rotisserie Chicken - If you want to change the protein and need an very easy weeknight meal, use rotisserie chicken.
Variations IdeasThe great thing about casseroles is you can mix in or change up the ingredients to what you have.
Change the Protein - If you prefer, you can use turkey meat or chicken. Casserole will still be so delicious.
Use different Chips - You can use tortilla chips instead of cheese Doritos if you prefer.
Sneak in Vegetables - This casserole is a great way to sneak in those vegetables. Dice up some carrots and broccoli and the kids wouldn't be able tell they are eating them.
Mix in Beans - Mix in some black beans, red bell pepper or pinto beans for an even hearty and filling casserole.
Use different Cheeses - We used cheddar cheese in this recipe, but you can also use Colby Monterey Jack Cheese or Mexican Cheese Blend. Pepper Jack Cheese is a great substitution if you want it a little spicy.
