You will need a 3 quart (approximately 9 x 13 inch) baking dish. I like to use a clear glass one so I can watch the cheese shreds melting while it's in the oven.
- Cook the quinoa according to your preferred method. (Both stovetop and Instant Pot instructions are provided in the recipe card at the bottom of this post.)
- Saute the onion, garlic, bell pepper, and spices.
- Stir in the quinoa, black beans, tomatoes, and corn.
- Stir in half of the vegan cheese shreds.
- Transfer the mixture to a baking dish. Top the casserole with the remaining vegan cheese and bake.
After cooking the quinoa, drain off any water that hasn't been absorbed. Otherwise you'll end up with a soggy casserole.
This black bean quinoa casserole is delicious topped with green onions and avocado, or some quick 4-ingredient guacamole. Or you can add some chopped tomatoes and sliced olives.
And I highly recommend serving it with some hot sauce, cherry tomato salsa, or avocado salsa verde and tortilla chips on the side. I like using the chips to scoop up this delicious dish. Plus since not everyone enjoys spicy food, I like to let each person add as much or as little salsa as they like.
Storing and freezing
Leftovers will keep refrigerated in an airtight container for up to 3 days and can be reheated in the oven or microwave. It's perfect for meal prep and taking to work for lunch.
Or freeze portions in glass containers with lids once the food has cooled to room temperature. Defrost overnight in the refrigerator before reheating.
Refer to the FDA Food Storage Guidelines for more information.
The grains of quinoa are coated in a naturally occurring chemical called saponin that tastes bitter to many people. By rinsing the quinoa in a fine mesh strainer before cooking it, you can eliminate the unpleasant flavor.
1 cup uncooked quinoa is approximately equal to 3 cups cooked.
If cooking quinoa on the stovetop , you will need 2 cups of water to cook 1 cup of quinoa. In an Instant Pot or other electric pressure cooker, you will only need 1¼ cup of water to cook 1 cup of quinoa.
