More About This Recipe

  • With layers of Mexican flavors and melty cheese, this vegetarian casserole is one even meat-lovers will want to try! Easy to assemble and quick to the table, this enchilada casserole is everything dinner was meant to be. I love casseroles. They're a complete meal in one simple dish and they always spell c.o.m.f.o.r.t. And what could be a better comfort food than a Mexican casserole? Better yet, a Mexican casserole that not only tastes amazing but is packed full of ingredients that will nourish both body and soul. My casserole was inspired by skinnytaste.com's fantastic recipe. Whole wheat tortillas are layered with black beans, corn, salsa, butternut squash, spices and oozing with cheese... this is a meatless casserole that even the most passionate carnivores will love! It's super easy to put together. Using pre-cut butternut squash (found in the refrigerated section of the produce aisle) saves time and effort. The meal prep is simply a matter of adding the ingredients to a saucepan to simmer with the seasonings and then layering them between the tortilla shells. It's that simple. This is also the perfect make-ahead meal. Assemble everything, then cover and refrigerate until you're ready to bake it. Voila! A delicious Mexican-style casserole that will have your taste buds dancing the salsa!
