Step‑by‑Step Instructions for Vegetarian Stuffed Pepper Casserole
Step 1: Prepare Oven & Pan
Preheat your oven to 375°F (190°C) and generously grease a 9×13 inch baking dish with olive oil or cooking spray. This ensures that your vegetarian stuffed pepper casserole doesn’t stick to the pan, making cleanup a breeze. Set the dish aside while you begin preparing the filling.
Step 2: Sauté Peppers
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the diced yellow onion and sauté for 4-5 minutes until it becomes translucent. Next, add minced garlic and sliced bell peppers, cooking for an additional 5-7 minutes until the peppers soften and brighten in color, releasing their sweet aromas.
Step 3: Combine Ingredients
Stir in the uncooked long-grain white rice, rinsed black beans, chili powder, ground cumin, smoked paprika, and dried oregano. Toast the mixture over medium heat for about 1 minute, allowing the rice and spices to absorb the flavors. This step is crucial for infusing your vegetarian stuffed pepper casserole with a rich taste.
Step 4: Simmer
Pour in the undrained diced tomatoes, tomato sauce, and vegetable broth. Stir the mixture well and bring it to a gentle simmer over medium heat. Allow it to cook for about 5-7 minutes, letting the flavors meld together and the rice absorb some of the liquid, creating a luscious filling for your casserole.
Step 5: Assemble Casserole
Transfer the hearty filling into your greased baking dish, spreading it out evenly with a spatula. Make sure to distribute the mixture well for even cooking. This vegetarian stuffed pepper casserole combines layers of flavor and texture that will be absolutely delightful once baked.
Step 6: Bake Covered
Cover the baking dish tightly with aluminum foil and place it in the preheated oven. Bake for 45 minutes, allowing the rice to become perfectly tender and soak up all the delicious juices. Keep an eye on it to ensure it doesn’t dry out as it bakes.
Step 7: Add Cheese & Final Bake
After 45 minutes, carefully remove the foil and sprinkle the shredded cheese generously over the top of the casserole. Return it to the oven uncovered and bake for an additional 10-15 minutes until the cheese is bubbly, melted, and golden brown, creating an irresistible topping for your vegetarian stuffed pepper casserole.
Step 8: Rest & Garnish
Once baked to perfection, remove the casserole from the oven and let it rest for 10 minutes. This resting time allows the flavors to meld. Garnish your completed dish with fresh cilantro for a burst of color and freshness before serving warm to family and friends.
Make Ahead Options
These Vegetarian Stuffed Pepper Casserole is perfect for meal prep enthusiasts! You can prepare the entire casserole up to 24 hours in advance. Just assemble the casserole as directed, cover it tightly with aluminum foil, and refrigerate. To maintain its deliciousness, be sure to let it come to room temperature for about 30 minutes before baking. When you’re ready to serve, simply bake as instructed, covering it for the first 45 minutes and then adding cheese for the last 10-15 minutes. This way, you’ll enjoy the same comforting flavors without the fuss, making it ideal for busy weeknights and spontaneous gatherings!
