Step‑by‑Step Instructions for Easy Vegetarian Enchilada Casserole

Step 1: Preheat Oven
Begin by preheating your oven to 400°F (200°C). This ensures the Easy Vegetarian Enchilada Casserole will cook evenly and become perfectly bubbly once it’s ready. Preheating prepares your kitchen for the delicious aromas that will soon fill the air, so don’t skip this essential step.

Step 2: Prepare Filling
In a large mixing bowl, combine black beans, refried beans, diced red bell pepper, green chilis, corn, garlic powder, onion powder, cumin, smoked paprika, and salt. Use a fork to mix the ingredients thoroughly until fully combined. This hearty filling will add layers of flavor to your casserole, ensuring a delightful taste in every bite.

Step 3: Layer Enchilada Sauce
Grab a 9 x 13-inch baking dish and spread a thin layer of enchilada sauce on the bottom. This step prevents the tortillas from sticking and adds an extra burst of flavor to your Easy Vegetarian Enchilada Casserole. Make sure the sauce is evenly distributed to create a perfect foundation for the layers to come.

Step 4: Assemble Layers
Now it’s time to layer your casserole! Place 4 halved tortillas over the sauce, covering as much area as possible. Then, spoon ½ cup of enchilada sauce over the tortillas and carefully add half of your filling mixture on top, followed by ½ cup of cheese. Repeat this layering process, finishing with another layer of tortillas, sauce, and a generous topping of cheese.

Step 5: Bake
Cover the assembled casserole with aluminum foil to keep moisture in during baking. Place your dish in the preheated oven for 25 minutes. This covered baking will ensure that all the flavors meld together and the ingredients heat up beautifully for your Easy Vegetarian Enchilada Casserole.

Step 6: Broil for Perfect Finish
After 25 minutes, remove the foil and continue to bake for an additional 5 minutes. Then switch to broil for 1 minute, keeping a close eye on it until the cheese is bubbly and lightly browned. This step gives your casserole a delightful golden top, making it as visually appealing as it is delicious.

Step 7: Rest & Garnish
Once out of the oven, allow your Easy Vegetarian Enchilada Casserole to rest for 5 minutes. This resting period helps the layers set and makes serving easier. To finish, garnish with chopped onions, green onions, and cilantro. If desired, serve with slices of avocado and lime wedges for a refreshing touch!
