Vegetarian Enchilada Casserole from 100 Days of Real Food

Thank you Lisa for inviting me to share another guest post with your readers! We’re currently in the middle of the October Unprocessed challenge, and this is a perfect “unprocessed” recipe to make for your family – or for yourself, with plenty of leftovers!

I may not yet have kids of my own (I added that “yet” in there to give my mom hope), but I sure do know how to feed a crowd. Every year I throw a big New Year’s party in which we do a lot of cooking and eating together… oftentimes we’re making dinner for about 30 people.

So we’ve learned how to feed a hungry group quickly and efficiently. A few years back, my friend Dan made “Enchilada Casserole” for the crew, and it immediately became a part of our holiday dinner rotation. It’s easy to prepare, and barely any extra work to double or triple the recipe. You can also prepare the casserole in advance and just throw it in the oven an hour before dinnertime.

It’s easily adaptable to special diets, too.  Already vegetarian (adding meat is so not necessary — it’s hearty enough!), we usually make one “regular” version and one vegan version (just skip the cheese), and most people have trouble deciding which they like more. If you use corn tortillas, it can be gluten-free, too. A couple of years ago, I started using 100% whole wheat tortillas instead of white flour tortillas, and people didn’t even notice.

It helps to think of this dish as sort of a “Mexican Lasagna.” You’re basically layering the bean mixture, tortillas, veggies, and cheese the same way you’d build a lasagna. As you layer things together, tear the tortillas in halves or quarters as necessary to create a single layer. I usually start with one whole tortilla in the middle, and then tear another in half to create flat edges, which go on the outside of the pan. I may tear a third one in quarters and use that to fill in the gaps. It’s good if they overlap a little. Like so:

  • I’m splitting the ingredients list into two parts — the first are the "mandatory" ingredients (though I suppose you could omit the onion). The second are recommended additions — feel free to adjust, change, or add as you see fit. When assembling the dish, it helps to think of it as “Mexican lasagna,” since the tortillas are layered just like lasagna noodles.
Sauce Base & Tortillas
  • 1 tablespoon olive oil
  • 1 onion, diced
  • 2 cups enchilada sauce (or one large can)*
  • 1 can black beans, rinsed and drained
  • 2 cups of
  • Lisa's slow cooker refried beans (or 1 can low-sodium refried beans)
  • 10-12 homemade corn or whole wheat
  • tortillas

    *Using canned enchilada sauce speeds things up, but the sodium content is usually frustratingly high and it may have preservatives or other unwanted additives. Instead, you can use canned tomato puree or chunks (or fresh, diced tomatoes, simmered for a few minutes) with cumin, chili powder, oregano, garlic/garlic powder and any other spices as you see fit. It should be thin; the tortillas will absorb that extra moisture.
Extra Goodies
  • 1 small can of diced green chiles
  • 3 to 5 cloves crushed garlic
  • ½ to 2 large diced jalapeños (check for spiciness, jalapeños vary considerably)
  • 1 cup quartered mushrooms
  • Bunch of fresh spinach (frozen or canned works, too)
  • 1 cup corn
  • 1 cup potatoes, sliced into ¼″ rounds and then parboiled for 3-5 minutes
  • 1 cup shredded cheese
  • 1 avocado, sliced
  1. Heat the oil in a large saucepan over medium heat. Saute the diced onion for 3-4 minutes until it starts to soften.
  2. Reduce heat to medium-low and add the enchilada sauce, black beans, and refried beans to the saucepan. Stir slowly until mixed thoroughly.
  3. Add any “extra goodies” to the sauce (except cheese or avocado) and continue heating and stirring until it starts to simmer. Be sure to stir continuously, else it may start to splatter as it comes to a boil.
  4. Once everything is mixed well, turn off the heat and begin layering the casserole in a lightly greased 9×13 baking pan. Start by adding a thin layer of the sauce to the bottom (if you start with tortillas first, they may burn). Next add a layer of tortillas (see diagram above). Then alternate sauce and tortillas until there’s about ¼″ of space left (or you run out of sauce or tortillas!), ending with a layer of sauce on top. Be sure all the tortillas are covered by sauce; any tortilla that’s not covered will dry out.
  5. Sprinkle the cheese on top and cover with aluminum foil. "Tent” the foil so it’s not resting on the cheese (this makes it easier to remove later).
  6. Bake at 350°F for 40 minutes. (If doubling the recipe or using a deeper pan, you may want to bake a little longer.) Remove foil and bake for another 10 minutes, until cheese begins to brown. Allow to cool for at least ten minutes then serve with a few slices of avocado on top.
We recommend organic ingredients when feasible.

      And with a title like that “Unprocessed…” I would re-title this at least so you’re not sending mixed messages to the people who need better guidance….

      Made this for my family last night and they loved it!

        Yay! Glad to hear it, Dot. :)

      This was delicious! We used Lisa’s beans and it had so much flavor to it (we added quite a few of the mix-ins.) Thank you both for posting recipes like this. For those of us who are still trying to convert to all whole foods all the time, I appreciate shortcuts (such as canned enchilada sauce, canned beans) once in awhile. We have made huge progress this past year but sometimes I feel like I can’t make one more thing from scratch in a week and taking a shortcut here & there is helpful. Next time I will try one of the gravy enchilada sauces from scratch that your readers linked to.

      This is so good!!!! Did a little variation though… I oven roasted yellow tomatoes and garlic then puréed the tomatoes with a quarter cup of fresh cooked back beans (thickener) and then when cooking in a pan, added fresh green chili, paprika, chili powder and cayenne. Then for filling, fresh spinach, fresh mushrooms & bell pepper, black beans and oven roasted chicken (about 1 cup chicken)… Delish!!!

      This is a great and versatile recipe. We subbed diced summer squash for potato (because the garden is running over) and leftover roasted chicken for the black beans. Using leftover crock pot pinto beans. Made homemade corn tortillas and enchilada sauce (made extra to freeze). I don’t really understand all the comments about this not being real food. Pretty much any recipe is as real as you want to make it. For me this is a Sunday dinner, not a quick weeknight meal. Will definitely make again! Thanks.

      I am confused. Aren’t canned beans, canned enchilada sauce and shredded cheese all processed foods? Maybe I don’t understand what processed foods are? Someone please explain. Thanks!

      I would definitely double the “sauce”. This barely made enough for two layers. In the oven now so hopefully it doesn’t dry out.

      • Jessica |

        Made this last night and it was very good, be careful if using double the sauce. It definitely needs more sauce but double was too much. Ours ended up more like an enchilada chili or stew rather than a lasagna. It was still delicious and we ate it over tortilla chips, but it wasn’t quite what it was supposed to be :)

      I’ve recently found your site and have become very interested in following the idea of making a lifestyle change! Eating less processed foods and more foods from scratch! Has anyone considered developing recipes for diabetics?
      Thank you very much
