Gather the ingredients for this loaded walking taco casserole

For the base of this casserole you'll need olive oil, diced onion, minced garlic, finely diced chile, ground beef, taco seasoning, black beans, and chopped tomatoes. Once everything has simmered away and been layered in the bottom of a baking dish, scatter some shredded cheddar cheese and lightly crushed Doritos all over the top. For some fresh toppings to add to the final baked dish, we opt for sour cream, shredded lettuce, cherry tomatoes, and chopped cilantro.

Can I add different toppings to this walking taco casserole?

Absolutely, you can certainly switch up the toppings on your loaded walking taco casserole. This base of the dish makes for the perfect canvas for taco lovers to create their masterpiece. No sour cream? No problem — this can be swapped out for a dollop of guacamole or a scoop of Greek yogurt. Add extra freshness with sliced avocado or a scattering of tangy black olives, or perhaps some diced red onions to give a nice peppery crunch. 

Spice enthusiasts can kick it up a notch with jalapeños or even a drizzle of hot sauce. You can also experiment with different cheese varieties here. Pepper Jack, Monterey Jack, or a Mexican blend can bring distinct flavors. You might even get creative with the flavor of Doritos that you sprinkle on top, either opting for a classic cheese flavor or putting your favorite flavor to good use.

How should you store leftover taco casserole?

If you happen to have any leftover taco casserole, storing it for later is no problem. Once everyone has enjoyed their helpings, ensure you then let any remaining casserole cool to room temperature. Cover the baking dish with plastic wrap or transfer individual servings into airtight containers. This not only helps maintain the flavors but also makes reheating easier when you're ready to relish the deliciousness once more. Stored in the refrigerator, your taco casserole will keep well for up to four days. When you're ready to enjoy the leftovers, simply reheat individual servings in the microwave or warm the entire casserole in the oven, covering it with foil to prevent over-browning.

The flavors of this casserole actually tend to mingle and intensify as they are stored, so each bite will be just as tasty as the first. So, whether it's a quick lunch or a cozy fuss-free dinner, this casserole is perfect for a second round.
