Ingredients

• 2 cups cooked black beans (or one 15-oz can, drained and rinsed)
• 1 cup corn kernels (fresh, canned, or frozen)
• 1 red bell pepper, diced
• 1 small onion, finely chopped
• 2 cloves garlic, minced
• 1 cup diced tomatoes (canned or fresh)
• 1 cup cooked brown rice (or quinoa for a protein boost)
• 1 cup shredded cheese (cheddar, Monterey Jack, or vegan cheese alternative)
• 1/2 cup sour cream or plain Greek yogurt (optional, or use vegan sour cream)
• 1 tablespoon olive oil
• 2 teaspoons chili powder
• 1 teaspoon cumin
• 1/2 teaspoon smoked paprika
• Salt and pepper to taste
• Fresh cilantro for garnish
• Optional toppings: sliced jalapeños, avocado slices, lime wedges

Equipment

• 9×13 inch baking dish
• Large mixing bowl
• Skillet or frying pan
• Knife and cutting board
• Measuring cups and spoons
• Spatula or wooden spoon

Instructions

1. Preheat your oven to 375°F (190°C). Lightly grease your baking dish with olive oil or cooking spray.
2. Prepare the vegetables: In a skillet, heat the olive oil over medium heat. Add the diced onion and sauté until translucent, about 3-4 minutes.
3. Add garlic, bell pepper, and corn: Cook for another 5 minutes until vegetables are tender and fragrant.
4. Season the veggies: Stir in chili powder, cumin, smoked paprika, salt, and pepper. Mix well to coat all the vegetables evenly.
5. Combine the casserole filling: In a large bowl, mix the cooked black beans, cooked rice, sautéed veggies, and diced tomatoes. If using sour cream or yogurt, fold it in now for creaminess.
6. Layer the casserole: Spread half of the bean and veggie mixture evenly in the bottom of the baking dish. Sprinkle half of the shredded cheese over the layer. Repeat with the remaining mixture and cheese.
7. Bake the casserole: Place in the oven and bake for 25-30 minutes, until the cheese is melted, bubbly, and slightly golden on top.
8. Garnish and serve: Remove from the oven and let cool for 5 minutes. Sprinkle with fresh cilantro and add optional toppings like jalapeños, avocado, and lime wedges.

Tips & Variations

“For a vegan version, simply swap out cheese and sour cream for your favorite plant-based alternatives. You can also add extra veggies like zucchini, mushrooms, or spinach for added nutrition and flavor.”

• Make it spicy: Add chopped chipotle peppers in adobo sauce or a dash of cayenne pepper to the filling.
• Use different beans: Pinto beans or kidney beans work great too and add variety.
• Try quinoa: For a boost of protein and texture, substitute cooked quinoa for rice.
• Top with crunchy elements: Add crushed tortilla chips or pepitas on top before baking for a delightful crunch.
• Meal prep friendly: Assemble the casserole in advance and refrigerate for up to 24 hours before baking.
