Let's get started on this delightful casserole that brings the best of Mexican cuisine to your kitchen.


Here’s what you'll need to make this delicious casserole:

  • 1 cup quinoa (or rice as a substitute)
  • 2 cups vegetable broth
  • 1 can black beans (drained and rinsed)
  • 1 can corn kernels (drained)
  • 1 bell pepper (diced)
  • 1 small onion (diced)
  • 2 cloves garlic (minced)
  • 1 can diced tomatoes (with juice)
  • 1 can of green chilies
  • 1 teaspoon cumin
  • 1 teaspoon chili powder
  • 1/2 teaspoon smoked paprika
  • 1 cup shredded cheese (cheddar or Mexican blend; for a vegan option, use dairy-free cheese)
  • Salt and pepper to taste
  • Fresh cilantro (for garnish)
  • Sour cream and avocado (optional, for serving)

Potential Substitutes

  • Quinoa can be substituted with brown rice or cauliflower rice for a low-carb option.
  • Black beans can be replaced with pinto beans or kidney beans.
  • Bell pepper can be substituted with poblano or jalapeño for extra spice.


Step 1: Preheat the Oven

Preheat your oven to 375°F (190°C).

Step 2: Cook the Quinoa

In a medium-sized pot, bring the vegetable broth to a boil. Add the quinoa, reduce heat to low, cover, and simmer for about 15 minutes, or until the quinoa is cooked and the broth is absorbed.

Step 3: Prepare the Vegetables

While the quinoa is cooking, dice the bell pepper and onion, and mince the garlic. Drain and rinse the black beans and corn.


  1. Combine Ingredients:

In a large mixing bowl, combine the cooked quinoa, black beans, corn, bell pepper, onion, garlic, diced tomatoes with juice, green chilies, cumin, chili powder, smoked paprika, salt, and pepper. Mix well to ensure all ingredients are evenly distributed.

  1. Layer in the Baking Dish:

Lightly grease a 9x13-inch baking dish. Spread the mixture evenly in the dish. Top with the shredded cheese.


Step 1: Cover and Bake

Cover the baking dish with aluminum foil and bake in the preheated oven for 20 minutes. After 20 minutes, remove the foil and bake for an additional 10-15 minutes, or until the cheese is melted and bubbly.

Tips for Checking Doneness

  • The casserole is done when the cheese is fully melted and slightly golden around the edges.
  • You should see bubbles around the edges, indicating it’s heated through.


Garnishes and Sides

  • Top with freshly chopped cilantro for a burst of freshness.
  • Serve with a dollop of sour cream and slices of avocado for added creaminess.
  • Pair with a side of tortilla chips or a simple green salad to complete the meal.
