- This black bean and butternut squash enchilada casserole is amazing when hot right out of the oven. It tastes even better the next day, or 3-4 days later! I just finished the last slice of this casserole 5 days later, and I can tell you that it was better than the 1st day! I guess all the flavors really blend while sitting in the refrigerator for days. 🙂

How to make black bean and butternut squash casserole:
1) Heat 1 tablespoon olive oil in a large skillet on medium-high heat.
2) Add chopped onion, chopped green bell pepper and chopped red bell pepper, and seasonings.
3) Add corn to the skillet and roast the vegetables in olive oil on high heat until charred a bit.
4) Add rinsed black beans.
5) Add roasted butternut squash.
6) Mix all vegetables, add more spices and salt, if needed.
7) I used a casserole dish 11 inches x 8.5 inches x 3 inches deep. Add 1 cup of salsa to the bottom of the 3-inch deep casserole dish and spread to coat the bottom evenly.
8) Start layers. Layer 1: Place 4 corn tortillas over the salsa, overlapping to cover the bottom of the casserole dish.
9) Spread ⅓ of the vegetable mixture over the corn tortillas.
10) Top with ½ cup sour cream, dropping it in small dollops all over. Then spread it carefully over the veggies.
11) Pour ½ cup enchilada sauce evenly all over, spreading sour cream evenly all over.
12) Sprinkle with ½ cup Mozzarella cheese.
13) Repeat all layers 2 more times. Sprinkle the final layer generously with cheese. Use at least ½ and ¼ cups of Mozzarella cheese.
14) Cover with foil.
15) Bake at 375 F in the preheated oven for 25 minutes covered. Then remove foil. Bake for 10 more minutes uncovered.
