Essential Ingredients

Black Beans: Use canned beans for convenience; ensure they’re drained and rinsed to cut down on sodium.
-
Diced Tomatoes: Opt for fire-roasted tomatoes if you want an extra kick of flavor.
-
Bell Peppers: A mix of colors adds visual appeal and sweetness—choose red, yellow, or green!
-
Onion: Sweet onions work beautifully here; they caramelize nicely during cooking.
-
Corn: Fresh corn off the cob is ideal, but frozen sweet corn works just as well.
-
Chili Powder: This spice gives the casserole its signature warmth; adjust to your heat tolerance.
-
Cumin: Adds depth; don’t skip this essential spice!

Cheddar Cheese: Shredded cheese on top creates that melty goodness we all love.

Let’s Make it together

Sauté the Aromatics: In a large skillet over medium heat, add some oil and sauté chopped onion until translucent and fragrant—about 5 minutes should do the trick.
Add the Chicken: Toss in diced boneless chicken breasts into the skillet. Cook until they turn golden brown on all sides—about 8-10 minutes—ensuring they are no longer pink inside.
Mix in Veggies: Stir in diced bell peppers, black beans, corn, diced tomatoes, chili powder, cumin, salt, and pepper. Cook everything together until heated through—just another 5 minutes will suffice.
Add Quinoa: Fold in rinsed quinoa along with 1 ½ cups of water or chicken broth for extra flavor. Stir everything gently until combined.
Bake Away: Pour the entire mixture into your prepared baking dish. Top with shredded cheese if desired! Bake uncovered for about 30-35 minutes until bubbly and golden brown.
Let cool slightly before serving. Garnish with fresh cilantro if you fancy a pop of color!
