Roasted Veggie Enchilada Casserole Ingredients
For the Vegetables
• Cauliflower – Provides a hearty texture and absorbs flavors beautifully; substitute with broccoli for something different.
• Sweet Potato – Adds a touch of sweetness and a creamy texture; can be replaced with butternut squash for similar results.
• Red Bell Peppers – Offer vibrant color and natural sweetness; use green bell peppers for a less sweet option.
• Yellow Onion – Enhances depth of flavor and sweetness; white onion can create a sharper taste if preferred.
For the Base
• Extra-Virgin Olive Oil – Essential for roasting to enhance flavor and texture; avocado oil works as a higher smoke-point alternative.

• Red Salsa – Brings moisture and tang; feel free to use homemade or store-bought, or mix it up with green salsa for more heat.
• Fresh Cilantro – Introduces brightness and freshness; omit if you desire a more straightforward flavor.
• Corn Tortillas – The backbone of the casserole; use gluten-free tortillas to accommodate dietary needs.
For the Protein and Greens
• Black Beans – Packed with protein and fiber; lentils or chickpeas can be alternative protein sources.
• Baby Spinach Leaves – Adds a nutritious green layer; switch for kale if you’re looking for a heartier bite.
• Shredded Monterey Jack Cheese – Offers creaminess and flavor; opt for a vegan cheese alternative for a dairy-free version.
Step‑by‑Step Instructions for Roasted Veggie Enchilada Casserole
Step 1: Preheat and Prepare
Begin by preheating your oven to 400°F (200°C). Line two baking sheets with parchment paper for easy cleanup. While the oven is heating, gather your cauliflower, sweet potatoes, red bell peppers, and onion. This Flavor-Packed Roasted Veggie Enchilada Casserole starts with beautifully roasted veggies, so prepping them well is essential.
Step 2: Toss and Roast the Veggies
On one baking sheet, toss together the cauliflower and sweet potatoes with a drizzle of extra-virgin olive oil, ground cumin, salt, and pepper. On the other sheet, combine the red bell peppers and onion with the same seasonings. Roast both trays in the oven for 30-35 minutes, stirring halfway through, until the veggies are tender and wonderfully caramelized.
Step 3: Lower the Oven Temperature
Once your veggies are perfectly roasted, lower the oven temperature to 350°F (175°C). While waiting for it to cool, grease a 9-inch square baking dish with a little olive oil. This will help prevent sticking and ensure an easy serving of your Roasted Veggie Enchilada Casserole when it’s baked.
Step 4: Mix Salsa and Cilantro
In a medium bowl, stir fresh chopped cilantro into your red salsa. This added step enhances the flavor profile of the salsa, bringing brightness to your casserole layers. Start layering your ingredients to maximize the deliciousness of the Roasted Veggie Enchilada Casserole.
Step 5: Layer the Casserole
Spread ½ cup of the cilantro salsa mixture evenly on the bottom of the greased baking dish. Add a layer of corn tortillas, followed by half of the black beans, one-third of the roasted veggies, half of the baby spinach, and a third of the shredded Monterey Jack cheese. Repeat this layering process to build a hearty, colorful casserole.
Step 6: Final Layer and Bake
Finish with another layer of tortillas topped with the remaining salsa and the rest of the cheese. Cover the baking dish with foil to keep the moisture in and bake in the oven for 20 minutes. After that, remove the foil and bake for an additional 10 minutes until the cheese is bubbly and golden, creating an inviting aroma of your Roasted Veggie Enchilada Casserole.
Step 7: Cool and Serve
After baking, let your casserole cool for 10 minutes to allow it to set, making it easier to slice and serve. Garnish with additional fresh cilantro for an extra burst of flavor. Now, your Flavor-Packed Roasted Veggie Enchilada Casserole is ready to be enjoyed.

Make Ahead Options

To maintain quality, ensure that the veggies are thoroughly cooled before assembly to prevent excess moisture. When you’re ready to serve, simply bake the casserole as directed, adding a few extra minutes to ensure it’s heated through. Enjoy a delicious homemade meal with minimal effort!
