Ingredients
- 2 cups cooked brown rice
- 1 can (15 oz) black beans, rinsed and drained
- 1 cup corn kernels (fresh or frozen)
- 1 small onion, diced
- 1 bell pepper, diced
- 2 cloves garlic, minced
- 1 cup crushed tomatoes
- 1 tsp cumin
- 1 tsp smoked paprika
- ½ tsp chili powder
- ½ tsp salt
- ¼ tsp black pepper
- 1 cup shredded cheese (optional)
- 2 tbsp olive oil
- Fresh cilantro for garnish
Step-by-Step Instructions
1. Preheat the oven
Preheat your oven to 375°F (190°C) and lightly grease a medium casserole dish.
2. Sauté the aromatics
Heat olive oil in a skillet over medium heat. Add diced onion and bell pepper.
Cook for 4–5 minutes until softened and fragrant.
Add garlic and cook for another 30 seconds.
Micro-tip: Let the vegetables lightly caramelize. This builds deeper flavor in the finished casserole.
3. Build the flavor base
Stir in crushed tomatoes, cumin, smoked paprika, chili powder, salt, and pepper.
Simmer for 3 minutes so the spices bloom in the sauce.
4. Combine the casserole
In a large mixing bowl combine:
- Cooked brown rice
- Black beans
- Corn
- The tomato mixture
Mix until evenly coated.
This combination creates the hearty texture typical of a brown rice and black bean casserole for healthy weeknight dinners.
5. Assemble
Transfer the mixture into the prepared baking dish.
Sprinkle shredded cheese on top if desired.
For extra texture, gently press the mixture down so it bakes evenly.
6. Bake
Bake for 20–25 minutes until the top becomes slightly golden and the casserole is heated through.
7. Finish and serve
Remove from the oven and let it rest for 5 minutes before serving.
Top with chopped cilantro and serve warm.
For a balanced dinner pairing, consider adding a protein side like Air Fryer Chicken Breast from this recipe.
Quick-Fix Tip
If the casserole looks dry before baking, stir in ¼ cup vegetable broth. This keeps the rice soft and fluffy during baking.
Variations
Healthy Version
Add extra vegetables like zucchini, spinach, or mushrooms for additional nutrients and fiber.

Serving it with sweet breakfast treats like Sheet Pan Pancakes the next morning makes meal prep easier.
High-Protein Version
Boost protein by adding:
- Greek yogurt topping
- Extra beans
- Diced grilled chicken
This transforms the casserole into a high protein rice and bean casserole meal prep option.
You can also serve it alongside seafood like Fish Tacos.
Tips for the Best Flavor
1. Cook rice properly
Always cook brown rice until just tender before adding it to the casserole. Undercooked rice will remain firm even after baking.
2. Toast your spices
Heating spices briefly in the tomato mixture unlocks their essential oils and dramatically improves flavor.
3. Balance acidity
If the tomatoes taste too sharp, add a pinch of sugar or a squeeze of lime to balance the flavor.
4. Use fresh herbs
Cilantro or green onions added after baking brighten the entire dish and add freshness.
