Roasted Vegetable Enchilada Casserole

Have you ever had enchilada casserole? This version has layers of caramelized roasted vegetables with gooey cheese and sweet salsa. It’s vegetarian as is, but you can add whatever leftover protein you like.

A cheesy slice of Stacked Roasted Vegetable Enchiladas lifted out of a serving dish.

I know what you’re thinking — veggie enchiladas can’t be that good. And why is everything just thrown into a casserole dish like that?! It’s an enchilada abomination!


Obviously these aren’t traditional enchiladas. They are, however, super delicious. And full of roasted vegetables. (I love roasted vegetables more than a lot of things. More than some people, actually.)

It’s a great recipe to take to someone who is sick or just had a baby. It freezes and reheats beautifully. Our whole family loves these, too!

This has been the most popular recipe on my site for YEARS, so I hope you give it a try.

What vegetables do I use for Roasted Vegetable Enchilada Casserole?

I like this particular combination — cauliflower, sweet potatoes, bell peppers, and a poblano pepper. And some frozen corn, if I happen to have it.

I like the poblano peppers and red pepper because I love how they taste, but you can use a jalapeno for heat or just use another bell pepper.

Theoretically you could use any roast-able vegetable you like, but I like this combination because it doesn’t taste too “green” like broccoli & Brussels sprouts would taste. You want the flavors to blend in, not overpower the casserole.

Adding a yellow onion or another type of onion is nice, too. Can’t go wrong with caramelized onions.

Layering cheese and spinach for Stacked Roasted Vegetable Enchiladas

Why Would You Stack Enchiladas like a barbarian?

You may also be wondering why they don’t look like authentic enchiladas.

These vegetarian “enchiladas” are stacked. Stacked enchiladas have all the components of enchiladas except the tortillas and filling are stacked — casserole style. 

Stacking them make it WAY easier to assemble. 

And if I can get all of the enchilada flavor that I love finished more quickly, then that’s always a good thing, right?

This version doesn’t actually have any enchilada sauce, either. Maybe it should be called “Mexican Layered Casserole” except I’m pretty sure it’s not authentic Mexican either.

Naming recipes is hard, guys. But I promise you’ll love this one!

This enchilada recipe is also customizable. And fairly healthy. (Hello, check out all of the veg!) And it’s pretty. I love pretty food.

Layering salsa and tortillas for Stacked Roasted Vegetable Enchiladas

How to assemble an Enchilada Casserole

  1. After your filling is finished roasting, grease a 9×13 baking dish with cooking spray. You could also use a large skillet that is oven-safe.
  2. Put some salsa in the bottom of the dish (about 1/2 cup) along with a single layer of tortillas. You may need to cut some to create straight edges, but it doesn’t have to be perfect. Don’t overthink it. You could also use flour tortillas if you like them better and aren’t concerned with keeping this gluten-free.
  3. Add some of the vegetable mixture, some baby spinach (I put baby spinach in a lot of things. Mostly because my kids don’t mind it’s there.), and some grated cheese in a (relatively) even layer on top of the tortillas.
  4. Repeat the layers — salsa (or remaining sauce), tortillas, filling, spinach, and cheese. I put three layers, ending with cheese on top. If you have remaining tortilla pieces, just use them for something else or bake them and make some homemade tortilla chips!
  5. I baked mine for 20 minutes covered and then 10 minutes uncovered to get the cheese nice and melty. I like to toss on some sliced green onions or red onion and fresh cilantro right before serving for a little freshness.

Ways to Customize this Roasted Vegetable Enchilada Casserole

Add Protein

If you’re wanting to keep this vegetarian, sprinkle in some black beans as you’re layering the casserole.

If you’re a meat eater, add some leftover shredded taco meat or ground beef. Or chopped grilled chicken.

Make it spicy!

Add a can of green chiles or jalapenos to the vegetable mixture, use a few shakes of hot sauce in your salsa mixture or just use some hotter salsa. Extra hot pepper jack cheese is also delicious and adds some heat.

Fresh salsa mixed with fresh cilantro

Change up your sauce!

You may have noticed that these “enchiladas” don’t have enchilada sauce. (The Mexican food blasphemy continues…)

Instead, some fresh salsa is mixed with chopped cilantro for a lighter feel. Try using salsa verde or another kind of salsa you like. 

You could also use actual enchilada sauce. I have a great Homemade Enchilada Sauce recipe if you need it. It’s chili powder based and super easy to make into a spicy sauce or something more medium heat.

Grain-free tortillas & dairy-free cheese for an adapted version of Stacked Roasted Vegetable Enchiladas

Make it Grain-Free & Dairy-Free

Luckily it’s easy to find grain-free and dairy-free replacements for things like cheese and tortillas to use in vegan enchiladas .

I made a version of this omitting the corn and using Siete cassava tortillas and some soy-free vegan cheese from Moocho & Violife. 

I’ve always been suspicious of dairy-free cheese, but these two brands pleasantly surprised me.

Grain-free and Dairy-free Stacked Roasted Vegetable Enchiladas

This is the grain & dairy-free version — look how good it looks! It tastes almost just like the original, too.

Dairy free cheese doesn’t melt quite like the real thing, but this was pretty tasty. I even topped it with some Kite Hill dairy-free sour cream.

How to Freeze this Enchilada Casserole

Like lasagna, it’s not that much extra work to make a second pan of vegetarian enchiladas while you’re assembling the first one. Now that I think of it, you could also call this a Mexican lasagna.

Before I had my last baby I frozen a pan of this and it was a life-saver several weeks later on a couple of busy weeknights! Your future self will thank you for prepping some weeknight dinners.

You can do this a couple of ways:

  1. Assemble the casserole without baking it, then cover it with aluminum foil and freeze it. Make sure you don’t use a glass dish if you plan on freezing it. A frozen glass dish placed into a hot oven will explode. (I know this from experience. Ha.) Use a metal pan or one of those disposable aluminum pans. It’ll take 90-120 minutes to bake from frozen. Start if off covered with foil, then remove the foil for the last 20 minutes or so.
  2. Bake the casserole. Let it cool to room temperature. Cover with foil and freeze. Again, don’t use a glass baking dish. It will take around the same time to warm up — at least 90 minutes.
  3. Don’t need to freeze it? Assemble the casserole and cover/chill the day before you plan to cook it. I wouldn’t prep it too far in advance or the layer of corn tortillas might get a little mushy.

If you like this recipe, try a chicken version with a creamy green chile sauce — Stacked Chicken & Green Chile Enchiladas.

All of my enchilada recipes are freezer friendly, too. If you make one, go ahead and double it so you have an easy meal later in the month!

Top with with a layer of tortillas, salsa, vegetables, and cheese.
