Ingredients

1 cup quinoa (uncooked)
1 cup frozen corn
2/3 cup reduced-sodium chickpeas (drained and rinsed)
1/2 cup black beans (drained and rinsed)
1 cup red pepper (chopped)
1 cup Roma tomatoes (chopped)
1/2 cup onion (roughly chopped)
1/2 tablespoon cumin
1 tablespoon garlic (minced)
1/4 teaspoon salt
1 1/2 tablespoons sauce from a can of chipotle peppers in adobo sauce
2 cups reduced-sodium vegetable broth
Shredded cheddar cheese (for garnish, optional)
Fresh cilantro (for garnish)

Instructions

Step 1: Spray your slow cooker with cooking spray. Add the uncooked quinoa, frozen corn, chickpeas, black beans, red pepper, tomatoes, onion, cumin, garlic, salt, and chipotle adobo sauce. Stir until everything is well combined.
Step 2: Pour the vegetable broth over the mixture and stir again. Cover the slow cooker and cook on high for 3 to 4 hours. Check the texture around 3 hours to ensure quinoa is tender and the dish is cooked through.
Step 3: Once cooking is complete, taste and adjust seasoning with additional salt and pepper if needed.
Step 4: Serve the casserole garnished with shredded cheddar cheese and fresh cilantro if desired.

Tips & Variations

Use low-sodium broth and beans to control salt levels.
Add diced jalapeños for extra heat.
Swap cheddar cheese for pepper jack for a spicier finish.
Serve with a squeeze of fresh lime juice for a bright flavor boost.

Storage

Store leftovers in an airtight container in the refrigerator for up to 4 days. Reheat gently in the microwave or on the stovetop, adding a splash of broth or water if it seems dry.

FAQs

Can I use canned quinoa instead of uncooked?

This recipe relies on cooking quinoa in the slow cooker to absorb flavors and liquid, so canned quinoa is not recommended as it may lead to a mushy texture.

What can I use instead of chipotle peppers in adobo sauce?

If you can’t find chipotle peppers in adobo, substitute with a small amount of smoked paprika and a little hot sauce to achieve a similar smoky, spicy flavor.
