Vegetarian Stuffed Pepper Casserole Ingredients
• Get ready to create hearty comfort food!
For the Casserole Base
- Bell Peppers – Provides sweetness and vibrant color; using multicolored peppers enhances visual appeal.
- Yellow Onion – An aromatic base that deepens flavor; shallots can be a milder substitute.
- Garlic – Essential for that savory punch; fresh garlic is preferred, but powdered can suffice in a hurry.
- Rice (Long-Grain White) – The structural backbone of the casserole; consider quinoa or brown rice as healthy alternatives.
- Black Beans – Packed with plant-based protein and fiber; kidney beans or lentils can also work wonders.
For the Flavor Boosters
- Chili Powder – Infuses warmth and spice; feel free to swap with smoked paprika for a robust twist.
- Cumin and Smoked Paprika – Optional but enrich the dish’s flavor profile significantly.
- Dried Oregano – Lends an herbal touch; fresh oregano can brighten the flavor even more.
- Salt and Black Pepper – Essential for seasoning; adjust to your taste preferences.
For the Moisture and Binding
- Diced Tomatoes (Undrained) – Contributes moisture and acidity; both canned and fresh tomatoes work, just avoid overly watery options.
- Tomato Sauce – Binds ingredients while adding flavor; store-bought sauce is a convenient substitute if you’re short on time.
- Vegetable Broth – Enhances richness in cooking; low-sodium varieties keep it lighter, or use water if needed.
For the Topping
- Shredded Cheese (e.g., Cheddar, Monterey Jack) – Adds a gooey, golden finish; for a vegan option, choose dairy-free cheese to keep it plant-based.

Step‑by‑Step Instructions for Vegetarian Stuffed Pepper Casserole
Step 1: Prepare Oven and Pan
Preheat your oven to 375°F (190°C) while you grease a 9×13 inch baking dish or a deep skillet with cooking spray or olive oil. This preparation step sets the stage for your Vegetarian Stuffed Pepper Casserole, ensuring an easy release once it’s baked to perfection.
Step 2: Sauté Aromatics and Peppers
In a large skillet, heat 2 tablespoons of olive oil over medium heat. Add the chopped yellow onion and sauté until it turns translucent, about 5 minutes. Stir in the minced garlic, cooking for an additional minute, then add 2 cups of chopped bell peppers. Sauté until the peppers are slightly softened and vibrant, around 3-4 minutes.
Step 3: Combine Filling Ingredients
Once the vegetables are sautéed, reduce the heat to low and stir in 1 cup of long-grain white rice, 1 can of drained black beans, 2 teaspoons of chili powder, 1 teaspoon of cumin, and 1 teaspoon of dried oregano. Stir the mixture for about 1 minute to toast the spices, enhancing the depth of flavor for your casserole.
Step 4: Add Liquids and Simmer
Pour in one can of undrained diced tomatoes, 1 cup of tomato sauce, and 1½ cups of vegetable broth into the skillet. Stir everything well, then increase the heat slightly, bringing the mixture to a gentle simmer. This step is crucial as it ensures the rice will cook evenly in the following bake.
Step 5: Assemble Casserole
Once simmering, transfer the rice and vegetable mixture into your greased baking dish, spreading it out evenly. This creates a hearty base for your Vegetarian Stuffed Pepper Casserole, allowing the flavors to meld beautifully in the oven.
Step 6: Bake to Perfection
Cover the baking dish tightly with foil and place it in the preheated oven. Bake for 45 minutes, allowing the rice to cook through and absorb most of the liquid. When done, the dish should be bubbling gently and the rice tender—your hard work is really starting to come together!
Step 7: Add Cheese and Final Bake
After the initial bake, carefully remove the foil and sprinkle 1 to 2 cups of shredded cheese evenly over the top of the casserole. Return it to the oven uncovered for an additional 10-15 minutes, until the cheese is melted, bubbly, and lightly golden, creating that irresistible cheesy crust.
Step 8: Rest and Garnish
Once baked, take the Vegetarian Stuffed Pepper Casserole out of the oven and let it rest for at least 10 minutes. This resting time allows the flavors to meld and makes serving cleaner. Before serving, garnish with freshly chopped cilantro for a touch of brightness and flavor.

What if my casserole looks too dry after baking?
Very! If your casserole seems dry, it could be due to not enough liquid or overcooking. Next time, ensure you’re using enough broth or sauce and keep an eye on the baking time. If it does dry out, you can add a splash of vegetable broth or tomato sauce to rehydrate it while reheating.
