Vegetarian Enchilada Casserole

This vegetarian enchilada casserole is a delicious and filling vegetarian dinner idea! It’s simpler to make than rolling enchiladas and makes a crowd-pleasing meal where no one will miss the meat. It’s a spin on our popular enchilada casserole with chicken—and we like it just as much!

Who loves a good casserole? We’ll admit: we’re suckers for cozy comfort food every now and then. Sometimes it’s hard to find that hearty comfort vibe with vegetarian recipes—which is why we love this one!

Alex and I made our chicken enchilada casserole and so many readers loved it that we decided to make a vegetarian version, too! It’s so much easier than rolling up tortillas, and the filling is deliciously hearty with black beans, refried beans, corn and red peppers. To keep things quick and simple, we like using purchased enchilada sauce (though homemade enchilada sauce works, too!). Layer it all up with tortillas and cheese and it makes a dinner everyone will rave about—we like to add a Mexican chopped salad if we’re feeling fancy!

How to make vegetarian enchilada casserole—step by step

Instead of rolling tortillas like traditional vegetarian enchiladas, this enchilada casserole layers tortillas with a filling of beans and veggies. You can simply cut the tortillas in half and lay them in a layer—like you see below!

Enchilada Casserole: Layering the tortillas

Step 1: Place a bit of enchilada sauce in the bottom of the pan (to prevent sticking). Layer 4 halved tortillas as shown.

Step 2: Spoon over enchilada sauce, bean and vegetable filling, and cheese.

Step 3: Then add a layer of sauce, then 4 more halved tortillas, filling, cheese, and sauce. Add a final layer of tortillas, remaining sauce, then remaining cheese.

Pro tips for success

This enchilada casserole is a great weeknight dinner or Meatless Monday recipe that can be put together quickly. Here are a few tips:

  • Use either corn or flour tortillas: Corn tortillas provide the most authentic flavor and make this a gluten free recipe, but flour tortillas work well too.
  • Grab your favorite enchilada sauce: As I mentioned, we like using store-bought sauce to keep things simple (we like Siete brand generally). But if you like making all things homemade (love that!), our homemade enchilada sauce takes just 15 minutes.

Enchilada casserole variations

Here are a few other fun variations for this vegetarian enchilada casserole:

  • Spicy: Adjust the spice in this recipe by using mild or hot enchilada sauce, or add chopped jalapeños for extra kick.
  • Verde enchilada casserole: Substitute green enchilada sauce or salsa verde for the red enchilada sauce.
  • Sweet potato enchilada casserole: Make the filling from our sweet potato black bean enchiladas (or follow that recipe but use the tortilla layering instructions in this recipe).

Side dish ideas to make it a meal

We love that this is a hearty vegetarian dinner recipe that everyone loves! We recently served it to my parents with (we’ll be honest!) one of those bag salads from the grocery. When you have time, though, there are so many fun sides for enchiladas and enchilada casserole! Here are some ideas:

Storing leftovers

Leftover vegetarian enchilada casserole stays good for up to 3 days refrigerated. It also works frozen, though it becomes much softer after freezing. For make ahead ideas, this casserole can be made up to 24 hours in advance, then baked (in a metal or ceramic pan; avoid glass because of the risk of cracking).

Dietary notes

This enchilada casserole is vegetarian and gluten-free. For vegan or plant-based, use dairy-free cheese.

Frequently asked questions

Can I make enchilada casserole ahead of time?

Absolutely! Enchilada casserole is perfect for meal prep. You can assemble the entire casserole up to 24 hours before baking and store it covered in the refrigerator. You may need to add 5-10 minutes to the baking time if cooking from cold. You can also freeze the unbaked casserole for up to 3 months—just thaw in the refrigerator overnight before baking.

Can I make this recipe vegan?

Yes! Simply substitute the cheese with your favorite plant-based cheese alternative and use plant-based sour cream or cashew cream for topping.

What are the best toppings for enchilada casserole?

Serve your enchilada casserole hot from the oven with optional toppings like diced avocado, fresh cilantro, sliced green onions, lime wedges, and a dollop of sour cream or Greek yogurt. Pickled red onions also make a nice tangy addition!
