Vegetarian Peppers and Rice Casserole

Note to self: This tastes good! (I realized that for some reason, looking at pictures of or even smelling rice and tomatoes/tomato sauce together turns my stomach, but this really does taste good--and it smells great once it's cooked!)

Ingredients
For the Casserole Base:
Bell Peppers: 2 large, multi-colored , cored and chopped into 1-inch pieces
Olive Oil: 2 tablespoons, extra virgin
Yellow Onion: 1 large, chopped
Garlic: 4 cloves, minced
Long-Grain White Rice: 1 cup, uncooked
Black Beans: 1 (15-ounce) can, rinsed and drained (I used pinto because I was out of black)
Diced Tomatoes: 1 (15-ounce) can, undrained
Tomato Sauce: 1 (8-ounce) can
Vegetable Broth: 1 ½ cups, low-sodium (I used beef broth and water, because I had beef broth to use up)
Chili Powder: 1 tablespoon
Cumin: 2 teaspoons, ground
Smoked Paprika: 1 teaspoon
Dried Oregano: 1 teaspoon
Salt: 1 teaspoon, or to taste
Black Pepper: ½ teaspoon, freshly ground

For the Cheesy Topping:
Shredded Cheese: 2 cups, a blend of Monterey Jack and sharp cheddar works well

For Garnish (Optional):
Fresh Cilantro: ¼ cup, chopped
Sour Cream or Greek Yogurt

For serving:
Avocado: Sliced or diced

Instructions
1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13 inch baking dish or a large, deep cast-iron skillet with olive oil or cooking spray.

 
2. In a large, deep skillet or Dutch oven, heat the 2 tablespoons of olive oil over medium-high heat. Once the oil is shimmering, add the chopped yellow onion and sauté for 4-5 minutes, until it becomes soft and translucent. Add the minced garlic and cook for another minute until fragrant, being careful not to let it burn. Add the chopped bell peppers to the skillet. Continue to cook for 5-7 minutes, stirring occasionally. You want the peppers to soften slightly but still retain a bit of their crispness, as they will continue to cook in the oven.

 
3. To the skillet with the peppers and onions, add the uncooked rice, rinsed black beans, chili powder, cumin, smoked paprika, dried oregano, salt, and black pepper. Stir everything together for about one minute. This step is crucial as it “toasts” the rice and spices, waking up their flavors and allowing them to coat every ingredient evenly.

 
4. Pour in the undrained diced tomatoes, tomato sauce, and vegetable broth. Stir thoroughly to combine, ensuring the rice is fully submerged in the liquid. Bring the mixture to a gentle simmer.

 
5. Once the mixture is simmering, carefully transfer the entire contents of the skillet into your prepared 9×13 inch baking dish. If you used a large, oven-safe skillet (like a cast-iron skillet), you can skip this step and bake it directly in the same pan. Spread the mixture into an even layer.

 
6. Cover the baking dish tightly with aluminum foil. This traps the steam, which is essential for cooking the rice properly. Bake in the preheated oven for 45 minutes. At this point, the rice should be tender and should have absorbed most of the liquid.

 
7. Carefully remove the foil from the baking dish. Sprinkle the 2 cups of shredded cheese evenly over the top of the casserole. (I actually mixed some in, to get the cheese all through the casserole, not just on top.) Return the dish to the oven, uncovered, and bake for an additional 10-15 minutes, or until the cheese is completely melted, bubbly, and just beginning to turn golden brown on the edges.

 
8. Remove the casserole from the oven and let it rest on a cooling rack for at least 10 minutes. This is a critical step! It allows the casserole to set, making it easier to serve and allowing the flavors to meld together beautifully. After resting, garnish generously with fresh cilantro and serve hot with your favorite toppings.
