Best ways to enjoy it
One of the best things about Dorito Casserole is how versatile it is when it comes to serving. You can enjoy it straight from the baking dish or serve it in individual bowls for a more curated approach. Consider pairing it with a fresh salad or some homemade guacamole for added texture and flavors. You can also serve it with a side of refried beans or rice for a more complete meal.
How to store & freeze
If you find yourself with leftovers (which is rare, but it does happen!), storing them is simple. Let the casserole cool completely before placing it in an airtight container. It can be kept in the refrigerator for about 3-4 days. For longer storage, freeze the casserole for up to 2-3 months. Just make sure to wrap it securely to prevent freezer burn!
When reheating, ensure it’s heated all the way through before enjoying again. You can reheat it in the oven or microwave, adding a splash of water if it appears dry.
Helpful cooking tips
For best results, use lean ground beef to prevent excess grease, as you’ll likely want a clean casserole. If you love a little extra zing, try adding chopped jalapeños or diced bell peppers to the meat mixture for a flavor twist. Also, experimenting with different cheese blends can elevate the dish even further!
Creative twists
Feeling adventurous? Here are some fun variations for your Dorito Casserole. Swap out the crushed Doritos for other chips like Fritos or tortilla strips for a different crunch. You can also switch up how you season it—add a bit of cumin, chili powder, or your favorite hot sauce to kick the spice level up a notch. For a vegetarian take, use black beans, lentils, or even swapping the ground beef for a combination of mushrooms and quinoa for an earthy flavor profile.
