Picture this: vibrant bell peppers standing tall on your dinner plate, stuffed to the brim with a mouthwatering mixture of protein-rich quinoa, hearty black beans, and a melody of spices that dance on your taste buds with each bite. These Stuffed Bell Peppers with Quinoa and Black Beans aren’t just a meal – they’re a colorful celebration that brings together the best of plant-based protein and garden-fresh produce in one satisfying package. The peppers roast to tender perfection while their stuffing develops complex flavors that will have everyone at your table reaching for seconds.
What makes these stuffed peppers truly special is their versatility and nutritional powerhouse status. Unlike traditional meat-filled versions, this plant-forward take delivers the same satisfying experience while being completely vegetarian-friendly (and easily made vegan with one simple swap). The quinoa provides all nine essential amino acids, while the black beans contribute fiber and additional protein. Together with the vitamin-rich bell peppers, this dish delivers a complete meal that nourishes your body while absolutely delighting your palate. Best of all? They’re meal-prep friendly and arguably taste even better the next day.
These stuffed bell peppers have become a regular feature in my kitchen rotation, and for good reason. They strike that perfect balance between wholesome and crave-worthy, making them suitable for both weeknight dinners and special occasions when you want to impress guests without spending hours in the kitchen. The combination of textures – from the tender-crisp pepper shells to the fluffy quinoa and substantial beans – creates an eating experience that keeps you coming back for just one more bite.
What I particularly love about this recipe is how customizable it is. Don’t have quinoa on hand? Brown rice works beautifully. Looking to increase the protein content? Add some crumbled tofu or your favorite plant-based ground meat alternative. The foundation remains the same, but you can easily adapt it to suit your pantry and preferences. This flexibility makes it perfect for those nights when you need to whip up something nutritious without making a special trip to the grocery store.
Stuffed Bell Peppers with Quinoa and Black Beans
A colorful, protein-packed vegetarian main dish featuring bell peppers stuffed with quinoa, black beans, vegetables and spices, topped with melted cheese for a satisfying meal that’s both nutritious and delicious.
Ingredients
- 6 large bell peppers (any color, though red, orange and yellow offer sweeter flavors)
- 1 cup quinoa, rinsed thoroughly
- 2 cups vegetable broth
- 1 tablespoon olive oil
- 1 medium onion, finely diced
- 3 cloves garlic, minced
- 1 medium zucchini, diced
- 1 can (15 oz) black beans, drained and rinsed
- 1 can (14.5 oz) diced tomatoes with green chilies
- 1 tablespoon ground cumin
- 2 teaspoons chili powder
- 1 teaspoon smoked paprika
- ½ teaspoon oregano
- ¼ cup fresh cilantro, chopped (plus extra for garnish)
- 1½ cups shredded cheese (Mexican blend, pepper jack, or cheddar)
- Salt and freshly ground black pepper to taste
- Optional toppings: sliced avocado, sour cream, lime wedges
Instructions
1. Prepare the bell peppers: Preheat your oven to 375°F (190°C). Slice the tops off the bell peppers and carefully remove the seeds and membranes. If needed, slice a tiny bit off the bottoms to help them stand upright, being careful not to create holes. Place the peppers in a baking dish that fits them snugly.
2. Cook the quinoa: In a medium saucepan, combine the rinsed quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer for about 15 minutes until the liquid is absorbed and the quinoa is fluffy. Remove from heat and let stand, covered, for 5 minutes.
3. Prepare the filling: While the quinoa cooks, heat olive oil in a large skillet over medium heat. Add the diced onion and sauté until translucent, about 4 minutes. Add the minced garlic and cook for another 30 seconds until fragrant. Add the diced zucchini and cook for 3-4 minutes until slightly softened.
4. Combine the filling: Stir in the black beans, diced tomatoes with green chilies, cumin, chili powder, smoked paprika, and oregano. Simmer for about 5 minutes, allowing the flavors to meld. Remove from heat and stir in the cooked quinoa and fresh cilantro. Season with salt and pepper to taste.
5. Stuff the peppers: Fill each bell pepper with the quinoa-black bean mixture. Pour about ¼ cup of water into the bottom of the baking dish (this creates steam to help cook the peppers). Cover the dish tightly with foil.
6. Bake: Bake the covered peppers for 25 minutes. Remove the foil, sprinkle the tops with shredded cheese, and bake uncovered for an additional 8-10 minutes until the cheese is melted and bubbly and the peppers are tender.
7. Serve: Let the peppers rest for 5 minutes before serving. Garnish with additional fresh cilantro and your choice of optional toppings like sliced avocado, a dollop of sour cream, or a squeeze of lime juice.
Recipe Notes
For a vegan version, simply omit the cheese or substitute with your favorite plant-based cheese alternative. The filling can be made a day ahead and refrigerated, making assembly quick and easy when you’re ready to bake. If you have leftover filling, it makes an excellent burrito or taco filling, or can be enjoyed as a stand-alone quinoa bowl topped with avocado.
Storage and Reheating
These stuffed peppers keep beautifully in the refrigerator for up to 4 days. To reheat, place them in a microwave-safe dish and heat on medium power for 2-3 minutes, or warm them in a 350°F oven for about 15 minutes until heated through. You can also freeze the cooked peppers for up to 3 months. Thaw overnight in the refrigerator before reheating for best results.
What makes this recipe a true winner is how it transforms simple, accessible ingredients into something that feels special. The combination of smoky spices, hearty grains, and fresh vegetables creates layers of flavor that develop further as they bake inside the pepper. The bell pepper isn’t just a vessel here—it becomes an integral part of the dish, infusing the filling with its sweet notes while providing that perfect slight resistance when you cut into it.

Each time I serve them, even dedicated meat-eaters find themselves surprised by just how satisfying this plant-forward dish can be.
