Before You Start
Preheat your oven and grab a large baking dish — everything mixes right in one bowl, no extra mess.

Ingredients
- 1 cup uncooked quinoa, rinsed
- 1 can (15 oz) black beans, drained and rinsed
- 1 cup corn (fresh, canned, or frozen)
- 1½ cups vegetable broth
- 1 cup salsa
- 1 teaspoon cumin
- 1 teaspoon chili powder
- ½ teaspoon garlic powder
- Salt and pepper to taste
- 1½ cups shredded cheese (cheddar or Mexican blend)

Instructions
- Mix the base
In a large bowl, stir together quinoa, black beans, corn, broth, salsa, and all seasonings. Everything should look evenly combined and slightly soupy — that’s what cooks the quinoa. - Transfer and cover
Pour the mixture into a greased baking dish and spread it evenly. - Bake
Cover tightly with foil and bake at 375°F for 35–40 minutes. You’ll know it’s ready when the quinoa looks fluffy and the liquid is absorbed. - Add cheese
Remove foil, sprinkle cheese evenly over the top, and bake uncovered for another 10 minutes until melted and bubbly. - Rest briefly
Let the casserole sit for 5 minutes before serving so it sets up nicely.
