Growing up, enchiladas were always a family favorite at our dinner table. But as my family leaned more towards plant-based meals, I found myself craving that same hearty, comforting dish—just without the meat.

That’s when this Vegetarian Enchilada Casserole became a household staple. It’s packed with vibrant veggies, protein-rich black beans, and melty Monterey Jack cheese, all layered between soft corn tortillas. 

Plus, it’s simple enough for a busy weeknight but delicious enough to impress at a weekend potluck. Trust me, even the biggest meat lovers in my family come back for seconds!

Tools You’ll Need

Step-by-Step Instructions for Vegetarian Enchilada Casserole

Step 1: Preheat the Oven

Preheat your oven to 400°F (200°C). Lightly grease a 9×13-inch baking dish with a little olive oil or nonstick spray to prevent sticking.

Step 2: Prepare the Vegetables

Chop the red bell peppers, onion, cauliflower, and sweet potato into bite-sized pieces. This ensures even cooking and a good texture in the casserole.

Step 3: Roast the Vegetables

Spread the chopped vegetables on a large baking sheet. Drizzle with 2 tablespoons of olive oil, then season with salt and pepper. Toss to coat evenly. Roast for 25-30 minutes, stirring halfway through, until the veggies are tender and slightly caramelized.

Step 4: Cook the Spinach and Beans

In a large skillet over medium heat, add the remaining ½ tablespoon of olive oil. Add the baby spinach and sauté for 1-2 minutes until wilted.

Step 5: Add the Black Beans

Once the spinach is wilted, stir in the black beans and ½ teaspoon of cumin. Cook for another 2-3 minutes until everything is heated through. Remove from heat.

Step 6: Layer the Casserole

Spread ½ cup of salsa on the bottom of the prepared baking dish. Arrange 5 corn tortillas over the salsa, overlapping as needed.

Step 7: Add the First Filling Layer

Top the tortillas with half of the roasted vegetables, half of the spinach and bean mixture, and ¾ cup of Monterey Jack cheese.

Step 8: Repeat the Layers

Add another layer of 5 corn tortillas followed by the remaining roasted vegetables, remaining spinach and bean mixture, and ¾ cup of cheese.

Step 9: Finish with Salsa and Cheese

Place a final layer of tortillas on top. Pour the remaining salsa over the tortillas, spreading it evenly. Sprinkle the remaining 1 cup of cheese on top.

Step 10: Bake the Casserole

Cover the dish with aluminum foil and bake for 20 minutes. Remove the foil and bake for an additional 10-15 minutes, until the cheese is bubbly and golden brown.

Step 11: Let It Cool

Remove the casserole from the oven and let it sit for 5 minutes before serving. This helps the layers set and makes slicing easier.

Step 12: Garnish and Serve

Sprinkle chopped fresh cilantro over the top for a burst of freshness. Serve warm with your favorite toppings like avocado slices, sour cream, pickled jalapeños, or a squeeze of lime. Enjoy!
