Ingredients
Main Ingredients for Stuffed Bell Pepper Casserole
– 4 large bell peppers, diced (choose your favorite colors)
– 1 cup quinoa, rinsed under cold water
– 2 cups low-sodium vegetable broth
– 1 can (15 oz) black beans, drained and rinsed
– 1 cup corn kernels (fresh or frozen, thawed if frozen)
– 1 cup diced tomatoes (canned or fresh)
– 1 teaspoon ground cumin
– 1 teaspoon smoked paprika
– 1 teaspoon garlic powder
– 1/2 teaspoon onion powder
– 1 cup shredded cheese (cheddar or Mexican blend)
– Salt and black pepper to taste
– 2 tablespoons olive oil for sautéing
– Fresh cilantro leaves, chopped (optional)
When you select bell peppers, each color has its own flavor. Red peppers are sweet, yellow peppers are fruity, and green ones are more bitter. Mix them for a colorful dish.
For the vegetable broth, go for low-sodium options. They bring flavor without making the dish too salty. You can make your own broth too, using leftover veggie scraps. Just simmer them with water for a few hours.
Optional Ingredients
You can add some extra flavor with seasonings. Try chili powder or oregano for a twist. You can also use ground turkey or cooked lentils instead of black beans for a protein boost.
For garnishes, consider adding sliced avocado or a dollop of sour cream. Fresh cilantro adds a nice touch, too, brightening the dish with color and taste.
Step-by-Step Instructions
Preparation Steps
1. Preheat your oven to 375°F (190°C). This makes sure it’s hot for baking.
2. In a medium pot, bring 2 cups of low-sodium vegetable broth to a boil.
3. Rinse 1 cup of quinoa under cold water. Add it to the boiling broth.
4. Lower the heat to a simmer, cover, and cook for 15 minutes.
5. Once the quinoa absorbs the broth, remove it from heat. Let it cool a bit.
Cooking Instructions
1. In a large skillet, heat 2 tablespoons of olive oil over medium heat.
2. Add 4 large diced bell peppers to the skillet. Sauté for 5-7 minutes.
3. Stir the bell peppers until they soften and turn bright.
4. Add 1 can of black beans, 1 cup of corn, and 1 cup of diced tomatoes to the skillet.
5. Next, add the cooked quinoa. Sprinkle in 1 teaspoon of cumin, 1 teaspoon of smoked paprika, 1 teaspoon of garlic powder, and 1/2 teaspoon of onion powder.
6. Season with salt and black pepper. Mix well and heat for another 3-5 minutes.
Baking Instructions
1. Take a greased 9×13-inch baking dish. Transfer the mixture from the skillet into the dish.
2. Spread the mixture evenly in the dish. Top it with 1 cup of shredded cheese.
3. Cover the dish tightly with aluminum foil. Bake in the preheated oven for 25 minutes.
4. After 25 minutes, remove the foil. Bake for another 10-15 minutes until the cheese is golden and bubbly.
5. Once done, let the casserole cool for a few minutes. Garnish with chopped cilantro before serving.
Tips & Tricks
Cooking Tips for Perfect Texture
To ensure your quinoa is fluffy, rinse it well before cooking. This step removes the bitter saponins. When you cook it, use low-sodium vegetable broth for added flavor. Bring the broth to a boil, then simmer for about 15 minutes. Wait until all the liquid is gone. Fluff it with a fork after it cools a bit. This method gives you light and airy quinoa.
When sautéing bell peppers, heat olive oil in a large skillet. Use medium heat to avoid burning. Add diced peppers and let them cook for 5-7 minutes. Stir them occasionally. You want them soft but still vibrant. This step adds great flavor and color to your casserole.
Cheese Selection Tips
For the best melting cheese, I recommend using cheddar or a Mexican blend. These cheeses melt nicely and add rich flavor. You can also try pepper jack for some heat. If you prefer a dairy-free option, look for plant-based cheeses. Many brands now offer great melting cheeses that fit well in casseroles.
Serving and Presentation Tips
Garnish your casserole with fresh cilantro for a burst of color. This adds freshness and a nice touch. Serve directly from the baking dish for a cozy vibe. For a complete meal, pair it with avocado slices or a dollop of sour cream. These sides complement the flavors and make for a tasty dinner.

Variations
Vegetarian Variations
You can make this dish vegetarian by using different vegetables. Try zucchini, carrots, or mushrooms for extra flavor. You can also swap out black beans for lentils or chickpeas. These options boost protein and add a nice texture.
Meat Options
If you prefer meat, adding ground turkey, beef, or sausage works great. Brown the meat in the skillet before adding the other ingredients. This step brings out the meat’s flavor and keeps it juicy. Make sure to drain any excess fat for a lighter dish.
Dietary Adjustments
For gluten-free options, use quinoa and check that your broth is gluten-free. If you want a vegan version, just skip the cheese or use plant-based cheese. You can also add tofu for protein. These changes ensure everyone can enjoy this tasty casserole.
Storage Info
Storing Leftovers
To keep your stuffed bell pepper casserole fresh, place it in an airtight container. Refrigerate it right after it cools down. This helps prevent bacteria growth. You can store it in the fridge for up to 4 days. Make sure to label the container with the date.
Freezing Instructions
If you want to freeze the casserole, let it cool completely first. Then, cut it into portions. Wrap each piece tightly in plastic wrap, then place them in a freezer-safe bag. This way, you can pull out just what you need later. The casserole will last for up to 3 months in the freezer.
When you’re ready to eat, take a portion out of the freezer. Thaw it in the fridge overnight. To reheat, place it in a baking dish and cover it with foil. Bake at 375°F (190°C) for about 25 minutes or until it’s heated through. Enjoy your meal without losing flavor!
