Step‑by‑Step Instructions for Walking Taco Casserole
Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While it’s heating, take a 13×9 baking dish and spray it generously with nonstick cooking spray. This ensures that your delicious Walking Taco Casserole will come out easily once it’s baked, allowing for perfect serving without a mess.
Step 2: Brown the Meat and Onions
In a large skillet over medium heat, add the ground beef and diced onion, cooking until the meat is browned and the onion is softened, about 6-8 minutes. Make sure to stir occasionally to break up the beef and evenly brown it. Once cooked, drain any excess fat to keep your casserole from becoming greasy.
Step 3: Add Seasoning and Water
Next, stir in your taco seasoning along with 1 cup of water, bringing the mixture to a gentle boil. Keep stirring for about 2-3 minutes until the water evaporates slightly and the seasoning is well incorporated. This step infuses the beef with robust flavors that are essential for your Walking Taco Casserole.
Step 4: Mix in Additional Ingredients
Reduce the heat to low and mix in the black beans, diced tomatoes with green chiles, and sour cream until the mixture is heated through, about 3-4 minutes. This adds creaminess and richness to your filling, enhancing the overall flavor profile of the casserole.
Step 5: Layer the Casserole
To assemble, layer the bottom of your prepared baking dish with Fritos to create a crunchy base. Next, spoon half of the beef mixture over the Fritos, followed by a generous layer of shredded cheese. Repeat with another layer of Fritos, the remaining beef mixture, and top with the rest of the cheese.
Step 6: Bake the Casserole
Cover the dish tightly with aluminum foil and place it in the preheated oven. Bake for 15 minutes to allow the flavors to meld together. After that, remove the foil and let it bake for an additional 5 minutes or until the cheese is bubbly and starts to turn golden brown.
Step 7: Serve and Garnish
Once baked, take the Walking Taco Casserole out of the oven and let it sit for a few minutes to cool slightly. Serve it hot, garnished with additional Fritos and your choice of toppings like green onions, guacamole, or salsa for a vibrant and flavorful finish.
