TACO CASSEROLE WITH DORITOS
Doritos Casserole is a layered Mexican casserole, a.k.a. a taco casserole! It's made with two layers of crushed Doritos that encompass a filling of taco-seasoned ground beef mixed with fire-roasted tomatoes and freshly grated cheese. The whole shebang is topped with more cheese and baked until bubbly!
When it comes out of the oven, top with your favorite taco toppings, serve and enjoy!
DORITOS CASSEROLE INGREDIENTS
The ground beef filling consists of sautéed yellow onion, lean ground beef, taco seasoning, unsalted beef broth, and canned fire-roasted diced tomatoes. It is important that you use a low-sodium beef broth. The regular beef broth would make the filling far too salty. If you can't find fire-roasted tomatoes, feel free to substitute plain, diced tomatoes (also from a can).
The filling lies somewhere between savory taco meat and a hearty Texas chili (no beans, of course). It's thickened with a quick and easy cornstarch slurry, made up of water and cornstarch.
And, of course, you can't have a Mexican Doritos Casserole without the Doritos! For this recipe, we stuck with standard Nacho Cheese Doritos, but the plain Yellow Corn Doritos would also be delicious in this casserole.
Cheese goes both in the filling and on top of the casserole. You can use Cheddar, Monterey Jack, or a blend of the two. Freshly grated is best if you have the time.
BEEF SUBSTITUTIONS
You can make Mexican Doritos Casserole a little lighter by subbing in a pound of any of the following proteins:
- Ground Turkey
- Ground Chicken
- Shredded Chicken
Poultry does not require as much seasoning as beef, so if you use one of these substitutions, omit the Kosher salt and pepper from the recipe entirely.
WHAT ARE DORITOS?
Originally, Doritos were simply corn chips (also known as tortilla chips) and actually, they still are. Only now, they come dusted in a variety of flavors. The most famous flavor being Nacho Cheese, which made its culinary debut in the early 1970s.
HOW TO MAKE DORITOS CASSEROLE
- Cook the Onions - Add the oil to a large pan over medium-high heat and allow it to come to temperature. Then, add the onions and sauté until softened.
- Add Beef and Taco Seasoning - Add the ground beef and the taco seasoning, breaking the beef apart with a wooden spoon. Cook until the beef is completely cooked through.
- Add Broth and Tomatoes - Next, add the beef broth, canned tomatoes, salt, and pepper to the pan, stir to combine, and allow the mixture to come to a simmer.
- Simmer, Add Cornstarch Slurry, and Simmer More - Once the mixture has reached a simmer, make the cornstarch slurry. Add the cornstarch to a small bowl with the water and mix to combine. Then, add the mixture to the beef and simmer a few minutes more, and stir in 1 cup of the cheese.
- Assemble Casserole - Add half of the crushed Doritos to the bottom of the casserole dish. Then, add the beef mixture, followed by the remaining Doritos, and end with the remaining shredded cheese, and bake for 20 minutes.

CAN YOU MAKE DORITO CASSEROLE AHEAD OF TIME?
Yes! You can make Mexican Doritos Casserole in advance. To do so, have your grated cheese ready and prepare the ground beef filling. Transfer the beef and the remaining shredded cheese to separate airtight containers and refrigerate for 2-3 days.
The day you're ready to serve, microwave the beef mixture until just warm (about 1 ½ minute on high), assemble the casserole and bake as directed!
