Step 1
Preheat the oven to 350 F. Coat a 9×13 pan with olive oil or nonstick cooking oil spray and set aside.
Step 2
In a large pot, cook the polenta according to package instructions. When polenta is almost done cooking, stir in butter and 4 ounces of shredded cheese until creamy.
Step 3
Next stir in the minced garlic, onion (see notes below), salt, and chili powder with the polenta. Mix thoroughly.
Step 4
Transfer polenta mixture into the 9×13 pan and spread until even, reaching each corner. If polenta is too runny or moist, parbake it at 350F for 15 minutes, then add the rest of your layers and bake again.
Step 5
In a medium-sized bowl, stir together the black beans, cumin, garlic powder, cayenne, and black pepper. Evenly distribute the black beans on top of the polenta.
Step 6
Layer the tomatoes and green chiles over the black beans.
Step 7
Finally, add the remaining shredded cheese evenly on top of the tomatoes and green chiles. Add more than 2 oz, if desired.
Step 8
Bake for 30 minutes or until the edges start to brown.
Step 9
Then cover with aluminum foil and bake for an additional 5 -10 minutes or until the center of the casserole is baked through and edges are golden brown.
Step 10
If desired, broil until the edges and cheese are browned and crispy. Remove from the oven and let cool for 5 minutes before slicing.
Step 11
Add optional toppings when platting.
