- Fire-Roasted Diced Tomatoes – 1 (14.5-ounce) can. These tomatoes introduce a slightly smoky flavor.
- Kosher Salt – ½ teaspoon. Seasoning enhances the flavors of the ingredients.
- Black Pepper – ½ teaspoon. This adds a mild heat and depth to the dish.

How to Make Doritos Casserole
Step 1: Preheat and Prepare
Preheat your oven to 350°F. Grease a 9x13-inch casserole dish to prevent sticking.
Step 2: Sauté Onions
Heat the oil in a large pan over medium-high heat. Add the diced onions and sauté until they soften, about 5 minutes.
Step 3: Cook the Beef
Add the ground beef to the pan along with the taco seasoning. Cook until the beef is fully cooked, breaking it apart as it cooks.
Step 4: Add Broth and Tomatoes
Stir in the beef broth, fire-roasted diced tomatoes, salt, and pepper. Allow this mixture to simmer for about 8-10 minutes to blend the flavors.
Step 5: Thicken the Mixture
Prepare a cornstarch slurry by dissolving the cornstarch in a little water. Add this to the beef mixture and stir until it thickens.
Step 6: Combine Cheese
Mix in 1 cup of grated cheese with the beef mixture until it melts and combines well.
Step 7: Layer the Casserole
In the greased casserole dish, layer half of the crushed Nacho Cheese Doritos. Spread the beef mixture on top, then add the remaining Doritos and sprinkle on the rest of the cheese.
Step 8: Bake
Bake in the preheated oven for 20 minutes until the cheese is bubbly and golden. Let it cool slightly, then serve with your favorite toppings.

Pro Tips from My Kitchen
✓ Prep Your Ingredients – Having all your ingredients ready before you start makes the cooking process smoother and faster.
✓ Use Freshly Grated Cheese – Pre-packaged cheese can contain anti-caking agents, which can prevent it from melting smoothly. Grate it fresh for the best results.
✓ Don’t Overcook the Beef – Make sure the ground beef is just cooked through to avoid a dry texture in your casserole.
✓ Experiment with Toppings – Try topping the casserole with sliced jalapeños, sour cream, or fresh cilantro for added flavor and presentation.
✓ Let It Rest – Allow the casserole to sit for about 5 minutes after baking. This helps the layers set for easier serving.
What Makes This Recipe Work
- The combination of beef broth and tomatoes creates a flavorful sauce that keeps the casserole moist, while the Doritos add a delightful crunch.
- Layering the ingredients enhances the flavor and texture, with the melted cheese binding the components together beautifully.
- By sautéing the onions and browning the beef, you develop rich flavors that elevate the entire dish, making each bite satisfying.
