How to Make Dorito Casserole Recipe
Step 1: Prepare Your Oven and Dish
Start by preheating your oven to 350°F (175°C). Make sure to grease a 9×13-inch baking dish with non-stick spray so your casserole slides out easily and cleanup is a breeze. This little prep sets you up for smooth baking and perfect crust on the casserole.
Step 2: Brown the Ground Beef
In a large skillet over medium heat, cook the ground beef until it’s nicely browned, breaking it apart with a spatula as it simmers. Once cooked through, drain off any excess fat to keep the casserole flavorful yet not greasy. This step ensures your beef is tender and ready to soak up the taco seasoning.
Step 3: Add Taco Seasoning and Tomatoes
Mix in the taco seasoning packet along with the diced tomatoes with green chilies. Let this mixture simmer gently for about five minutes – this is where those robust chili flavors and spices meld beautifully with the meat, creating the savory heart of the Dorito Casserole Recipe.
Step 4: Create the First Layer
Spread a generous layer of crushed Doritos evenly across the bottom of your prepared baking dish. These chips form a crunchy base that will give your casserole that satisfying texture everyone loves. Next, spoon half of the seasoned beef mixture on top, then sprinkle half of the shredded cheddar cheese over it to start building those cheesy layers.
Step 5: Build Flavor with Sour Cream and More Layers
Spread the sour cream over the beef and cheese layer gently, ensuring even coverage. This creamy layer balances the bold taco spices and adds richness. Afterward, add the remaining beef mixture on top, followed by the last bit of shredded cheddar cheese. This layering is key for that melty, luscious cheese finish.
Step 6: Bake Until Bubbling Perfection
Pop your casserole into the oven and let it bake for 20-25 minutes. You’ll want to watch for the cheese to be fully melted and bubbling, with the edges slightly crisped. This bake time gives the dish its irresistible golden top and melds all the flavors and textures together wonderfully.
Step 7: Garnish and Serve Your Dorito Casserole Recipe
Once out of the oven, feel free to sprinkle shredded lettuce and diced tomatoes over the top for a burst of freshness and a pop of color. Serve your Dorito Casserole Recipe steaming hot and watch it disappear in no time—it’s truly a crowd-pleaser!
