- Step 9: Finish with the remaining Doritos and cheese evenly spread on top.
- Step 10: Cover the dish with foil and bake for 25 minutes until heated through and cheese is melted.

Tips & Variations
- For extra spice, add chopped jalapeños or use spicy taco seasoning.
- Swap pinto beans for black beans for a slightly different flavor and texture.
- Use a mixture of cheddar and Monterey Jack cheese if colby jack is not available.
- For a lighter version, use reduced-fat cheese and swap sour cream for Greek yogurt.
Storage
Store any leftovers in an airtight container in the refrigerator for up to 3 days. To reheat, place in an oven-safe dish covered with foil and warm at 350 degrees F until heated through, or microwave until warm. The casserole may lose some crunch over time but will still be delicious.

FAQs
Can I make this casserole ahead of time?
Yes, you can assemble the casserole a few hours in advance and refrigerate it before baking. Just add a few extra minutes to the baking time if baking straight from the fridge.
Can I substitute the Doritos with another chip?
Absolutely. Tortilla chips or another flavored chip can be used if you prefer, though Doritos add a distinctive cheesy flavor and crunch.

Instructions
- Preheat Oven: Preheat the oven to 375 degrees F (190 degrees C) and spray a 9 x 13-inch casserole dish with non-stick cooking spray to prevent sticking.
- Cook Ground Beef: In a large skillet over medium heat, cook the ground beef, breaking it apart with a spatula until fully browned. Drain excess grease to keep the dish from being too oily.

- Prepare Doritos: Break the Doritos chips into medium-sized pieces, ensuring they are not crushed too finely to maintain some crunch.
- Assemble Layers: Spread one-third of the broken Doritos evenly over the bottom of the casserole dish. Layer half of the beef mixture over the chips, then sprinkle one-third of the shredded cheese on top.
- Repeat Layers: Add another third of the broken Doritos chips over the cheese, top with the remaining beef mixture, and sprinkle with another third of the shredded cheese.
- Finish Layering: Spread the remaining Doritos chips on top, then finish with the last third of the shredded cheese to ensure a cheesy crust when baked.

- For extra heat, add jalapeños or hot sauce to the beef mixture.
- Drain the ground beef well to avoid excess grease making the casserole soggy.
- This casserole can be made ahead and refrigerated before baking. Just increase bake time slightly if baking from cold.
