It was one of those evenings when I opened my fridge and realized I had a handful of random veggies and a half-used block of cheese staring back at me.

I tossed together what I had, added a bit of this and that, and popped it into the oven, half-expecting a disappointing mess. But you know what? That first bite of this creamy loaded vegetarian enchilada casserole surprised me in the best way. The layers of melty cheese, tender beans, and vibrant veggies somehow came together into this cozy, satisfying meal that felt like a warm hug after a long day.

What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying texture without the fuss. Most are pantry staples, with some fresh veggies to brighten things up. Here’s what you’ll need:

• For the Filling:
• 1 can (15 oz / 425 g) black beans, drained and rinsed
• 1 cup (150 g) frozen corn, thawed (or fresh if in season)
• 1 medium red bell pepper, diced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup (150 g) mushrooms, sliced (optional but adds great umami)
• For the Sauce:
• 1 cup (240 ml) sour cream or Greek yogurt (I love using full-fat for creaminess)
• 1 cup (240 ml) enchilada sauce (store-bought or homemade)
• 1 teaspoon ground cumin
• 1/2 teaspoon smoked paprika
• Salt and pepper to taste
• For Assembly:
• 8 small corn or flour tortillas, cut into strips or quarters
• 2 cups (200 g) shredded cheese blend (cheddar and Monterey Jack work well)
• Fresh cilantro, chopped (optional garnish)
• 1 jalapeño, thinly sliced (optional for heat)

For best results, I recommend looking for a good-quality enchilada sauce—brands like Hatch or Old El Paso have reliable flavor. If you’re gluten-free, corn tortillas are the way to go. And if dairy is a concern, swapping sour cream for a dairy-free yogurt and using vegan cheese works surprisingly well here.

Equipment Needed

• 9×9 inch (23×23 cm) baking dish or similar size casserole dish
• Large skillet or sauté pan (for cooking veggies)
• Mixing bowls for sauce and filling
• Measuring cups and spoons
• Sharp knife and cutting board
• Spatula or wooden spoon

If you don’t have a 9×9 baking dish, a similarly sized oven-safe dish will do just fine. I’ve also used cast iron skillets for this recipe, which gives the casserole a nice crispy edge. For budget-friendly tools, simple stainless steel pans and glass baking dishes work perfectly well. I find that a non-stick skillet makes sautéing the veggies easier and less messy.

Preparation Method

1. Prepare the Veggies: Heat 1 tablespoon of oil in a large skillet over medium heat. Add the chopped onion and sauté for about 3 minutes until it starts to soften. Toss in the garlic and cook for another 30 seconds until fragrant.
2. Add the Peppers and Mushrooms: Stir in the diced red bell pepper and sliced mushrooms. Cook for 5 to 7 minutes, stirring occasionally, until the veggies are tender and any liquid from the mushrooms has evaporated.
3. Mix in Beans and Corn: Add the black beans and corn to the skillet. Stir together and cook for 2 minutes just to warm everything through. Season lightly with salt and pepper. Remove from heat.
4. Make the Creamy Sauce: In a bowl, whisk together the sour cream (or Greek yogurt), enchilada sauce, cumin, smoked paprika, and a pinch of salt and pepper. Taste and adjust seasoning if needed—this sauce should be flavorful but balanced.
5. Preheat Oven: Set your oven to 375°F (190°C) so it’s ready for baking once the casserole is assembled.
6. Assemble the Casserole: Lightly grease your baking dish. Spread a thin layer of the creamy sauce on the bottom. Next, add a layer of tortilla pieces, covering the base but not overlapping too thickly.
7. Add Filling and Cheese Layers: Spoon about one-third of the veggie and bean mixture evenly over the tortillas. Drizzle with some creamy sauce and sprinkle with a handful of shredded cheese. Repeat layering two more times — tortillas, filling, sauce, cheese — finishing with a generous cheese layer on top.
8. Bake: Place the casserole in the oven and bake for 25 to 30 minutes, or until the cheese is bubbly and golden brown on top. You should see the sauce bubbling around the edges, and the tortillas will have softened nicely.
9. Rest and Garnish: Let the casserole sit for about 10 minutes after removing from the oven. This helps it set for easier slicing. Sprinkle chopped cilantro and sliced jalapeños over the top before serving if you like a fresh, spicy kick.

Pro tip: If you find the casserole looking a bit dry while baking, gently spoon a little extra enchilada sauce over the top halfway through cooking. It keeps things creamy and luscious.

Cooking Tips & Techniques

One trick I’ve learned with this creamy loaded vegetarian enchilada casserole is to not overload the layers with too many tortillas. You want a good balance of sauce, filling, and tortillas so every bite has a mix of textures. Too many tortillas, and it gets a bit doughy instead of creamy and tender.

When cooking the veggies, make sure to let excess moisture evaporate fully—especially if you’re using mushrooms. Otherwise, the casserole can turn out watery, which dulls the flavors. Patience here really pays off.

Another tip: don’t skip resting the casserole after baking. It’s tempting to dig in right away, but letting it cool slightly helps the layers meld and makes serving cleaner. Plus, flavors deepen during that rest time.

For multitasking, you can prep the veggies and sauce while the oven is warming up, so assembly is quick. If you want a shortcut, canned roasted peppers can replace fresh bell peppers with a smoky note.

Lastly, I once forgot to season the sauce well enough, and the casserole tasted flat. So always taste your sauce before layering—it’s the flavor backbone here.

Variations & Adaptations

• Vegan Version: Use dairy-free sour cream and vegan cheese. Swap regular tortillas for gluten-free if needed.
• Spicy Kick: Add chopped chipotle peppers in adobo to the sauce or sprinkle cayenne for heat.
• Seasonal Veggies: In spring or summer, swap bell peppers and corn with zucchini, fresh tomatoes, or roasted poblano peppers.
• Different Protein: Add cooked lentils or crumbled tofu for extra protein punch without meat.
• Personal Favorite: I like to add a layer of sautéed spinach or kale for a green boost and slight earthiness that pairs well with the creamy sauce.

Serving & Storage Suggestions

This creamy loaded vegetarian enchilada casserole is best served warm, straight from the oven, with a sprinkle of fresh cilantro and maybe a dollop of sour cream or guacamole on the side. It pairs beautifully with a simple green salad or Mexican-style rice.

Leftovers keep well in an airtight container in the fridge for up to 4 days. To reheat, cover loosely with foil and warm in a 350°F (175°C) oven until heated through, or microwave individual portions—though the oven method keeps the texture better.

Freezing is also an option: cool completely, then wrap tightly and freeze for up to 3 months. Thaw overnight in the fridge before reheating. The flavors actually deepen after sitting, so it’s a great make-ahead meal.

Nutritional Information & Benefits

This casserole is a wholesome vegetarian option packed with fiber and plant-based protein from black beans and veggies. The beans and corn provide slow-digesting carbs that keep you full and energized. Using sour cream or Greek yogurt adds creaminess plus calcium and probiotics if you choose yogurt.

It’s naturally gluten-free if made with corn tortillas and can be made vegan with simple swaps. The spices like cumin and smoked paprika add antioxidants while keeping sodium levels moderate. Overall, this meal balances comfort with nutrition nicely, making it a solid choice for meatless dinners.

Conclusion

It’s not just about convenience or flavor, but the way it turns simple ingredients into a meal that feels both nourishing and indulgent. Whether you’re cooking for yourself or a crowd, it adapts easily to what you have on hand and always delivers that satisfying, cozy feeling.

Give yourself the freedom to swap ingredients and spice it up or tone it down. This recipe is flexible and forgiving, which is why it’s become a staple in my kitchen. I hope it becomes one of your favorites too—ready to comfort, impress, and fill your table with delicious, meatless goodness.
