My favorite ingredient is always the Doritos because they add crunch and cheesy flavor in every bite Once my sister and I competed to see who got the biggest chip on their plate and I still remember us giggling around the dinner table every time I make it

Storage Tips

Let the casserole cool to room temperature before covering and refrigerating Store leftovers in an airtight container for up to three days Doritos will soften so if you want to bring back the crunch bake leftovers uncovered at 350 degrees for about 10 minutes

Ingredient Substitutions

Swap the ground beef for ground chicken or turkey for a lighter option Use Greek yogurt instead of sour cream if desired Monterey Jack or cheddar cheese can replace Mexican blend Black beans can be left out or replaced with pinto beans for variety

Serving Suggestions

Serve with extra toppings on the side so everyone can customize their plate Pair with a simple salad of lettuce tomatoes and avocado or even scoop with more Doritos for a real treat This casserole also goes side by side with rice or refried beans for a full meal
