Chock full of veggies, black beans, cheese and homemade enchilada sauce, Quinoa Enchilada Bake with Black Beans is a fabulous vegetarian casserole to feed a small crowd. This Mexican quinoa recipe is freezer friendly and makes for easy leftovers. vegetarian + gluten free
Late summer and early fall veggies continue to make a showing at the farms and farmers markets, so I’m keeping them on the menu as long as I can. Just picked sweet corn from Bell’s Farm is hard to resist right off the cob, but I also love putting it in all things Mexican food. It also makes a great opportunity to whip up a black bean recipe!
Shucking sweet corn is a practice in patience. Removing the silk takes a bit of effort, but worth the pot of gold in the end. But, frozen corn can be easily subbed for fresh!
This vegetarian, gluten free, quinoa enchilada casserole recipe has all the late summer suspects. Fresh corn, zucchini, poblano or green bell pepper, and onions make a showing as well as hearty and texture rich quinoa, black beans and my made-in-a-blender easy homemade enchilada sauce. Best of all, this Quinoa Enchilada Bake gluten free casserole is freezer friendly.

- 2 tsp Fine Sea Salt
- 2 tsp Cumin ground
- 3 C (345g) Zucchini diced small, about one medium
- 1 1/2 C (210g) Corn Niblets fresh or frozen, about 1 ear of corn

- 2 C (200g) Pepper Jack or Monterey Jack Cheese
For Garnish (optional):

- Soak the quinoa over night covering it in at least 2" of water (if desired). Otherwise, simply rinse the quinoa through a fine mesh strainer until the water runs clear. In a medium sauce pot add the soaked (or unsoaked) quinoa and water. Stir in a pinch of salt and bring to a simmer. Cover, turn heat to medium-low, and simmer until tender and the 'tails' are showing. Soaked quinoa will take about 8 minutes and need to be drained while unsoaked quinoa takes about 15 minutes to cook (no draining needed). Drain any excess water and spoon into a large mixing bowl.
- Set oven rack in center and preheat oven to 350F (180C).Meanwhile heat the oil in a medium saute pan until it shimmers. Add the onion and bell (or poblano) pepper and saute allowing the veggies to set for 2-3 minutes at a time to sear, for about 8 minutes or until vegetables are tender. Sprinkle in the salt and cumin and stir so that the veggies are coated for one minute. Add the mixture to the bowl of quinoa.
- To the mixing bowl, add the zucchini, corn, black beans, enchilada sauce, adobo sauce and 1 1/2 C (150g) of pepper jack cheese. Stir throughly so that all the veggies are evenly distributed. Transfer the mixture into a 9"x13" (22cmx33cm) baker/casserole, smooth top and sprinkle the remaining cheese over the top. Cover wth foil tenting the center slightly so that it doesn't rest on the cheese and bake for 30-35 minutes until the cheese has melted and it's bubbly. Remove from oven and rest covered for 10 minutes. Garnish with options or serve garnishes on the side.
- Store in a covered container in the refrigerator for up to three days or in the freezer for up to one month. Thaw overnight in the refrigerator. To reheat, cover and bake in a preheated oven for about 15 minutes.
