Ingredients

• 4 large bell peppers (any color), tops sliced off and seeds removed
• 1 cup uncooked quinoa, rinsed
• 2 cups low-sodium vegetable broth (or water)
• 1 tablespoon olive oil
• 1 small yellow onion, finely chopped
• 2 cloves garlic, minced
• 1 medium zucchini, diced small
• 1 cup cherry tomatoes, halved (or 1 cup canned diced tomatoes, drained)
• 1 cup corn kernels (fresh, frozen, or canned and drained)
• 1 can (15 ounces) black beans, rinsed and drained
• 1 teaspoon ground cumin
• 1 teaspoon smoked paprika
• 1/2 teaspoon dried oregano
• 1/4 teaspoon red pepper flakes (optional)
• Salt and black pepper, to taste
• 1/2 cup shredded cheese (cheddar, Monterey Jack, or mozzarella) plus more for topping
• 2 tablespoons chopped fresh cilantro or parsley
• 1 lime, cut into wedges (for serving)
• Optional toppings: sliced green onions, avocado, plain Greek yogurt or sour cream

Instructions

1. Preheat the oven: Set to 400°F (200°C). Lightly grease a baking dish that will hold all four peppers upright.
2. Par-cook the peppers: Place the hollowed peppers in the dish cut-side up.

   Drizzle with a little olive oil and a pinch of salt. Bake for 12–15 minutes until slightly softened but still holding their shape.
3. Cook the quinoa: In a medium pot, combine rinsed quinoa and vegetable broth. Bring to a boil, then reduce heat to low, cover, and simmer 15 minutes, or until liquid is absorbed.

   Remove from heat and let sit covered 5 minutes, then fluff with a fork.

4. Sauté the aromatics and veggies: In a large skillet, heat olive oil over medium. Add onion with a pinch of salt and cook 3–4 minutes until translucent. Stir in garlic and cook 30 seconds until fragrant.
5. Add vegetables and spices: Add zucchini, tomatoes, and corn.

   Season with cumin, smoked paprika, oregano, red pepper flakes, salt, and pepper. Cook 4–5 minutes, stirring, until the zucchini is just tender and tomatoes start to break down.

6. Combine the filling: Stir in black beans and cooked quinoa. Taste and adjust seasoning.

   Remove from heat and fold in 1/2 cup shredded cheese and the chopped cilantro or parsley.
7. Fill the peppers: Spoon the quinoa mixture into the pre-baked peppers, packing lightly. Top with a little extra cheese if you like.
8. Bake: Return to the oven for 12–15 minutes, until the peppers are tender and the filling is hot and melty.
9. Finish and serve: Let cool for 5 minutes. Serve with lime wedges and any toppings you love.

How to Store

• Refrigerate: Store cooled stuffed peppers in an airtight container for up to 4 days.
• Freeze: Wrap each cooled pepper tightly, then place in a freezer-safe bag.

  Freeze up to 2 months. Thaw overnight in the fridge before reheating.

• Reheat: Microwave 2–3 minutes, or bake at 350°F (175°C) for 15–20 minutes until warmed through. Add a splash of broth if they seem dry.

Health Benefits

• Complete protein: Quinoa contains all nine essential amino acids, making it a strong plant-based protein source.
• High in fiber: Black beans, quinoa, and veggies help with satiety, digestion, and steady energy.
• Vitamins and antioxidants: Bell peppers bring vitamin C and carotenoids; tomatoes add lycopene; herbs offer phytonutrients.
• Heart-friendly fats: A touch of olive oil contributes monounsaturated fats that support heart health.
• Gluten-free and adaptable: Naturally gluten-free and easy to make dairy-free without losing protein or flavor.

What Not to Do

• Don’t skip rinsing the quinoa: Rinsing removes saponins, which can taste bitter.
• Don’t overbake the peppers: You want tender, not collapsed.

  Par-bake just until they soften slightly, then finish with the filling.

• Don’t under-season: The filling needs enough salt, spice, and acidity. Taste and tweak before stuffing.
• Don’t overload with moisture: Drain canned tomatoes and beans well. Excess liquid makes soggy peppers.
• Don’t forget texture: A little cheese on top or crunchy toppings like green onions and avocado make every bite better.

Recipe Variations

• Mediterranean: Swap black beans for chickpeas.

  Add chopped olives, sun-dried tomatoes, spinach, and feta. Season with oregano, garlic, and lemon zest.

• Southwest: Keep black beans and corn, add diced jalapeño, cilantro, and a squeeze of lime. Use pepper jack and extra smoked paprika.
• Italian: Stir in marinara, sautéed mushrooms, and spinach.

  Use mozzarella and a sprinkle of Parmesan with basil on top.
• Protein boost: Add cooked ground turkey, shredded rotisserie chicken, or crumbled tofu to the filling.
• Vegan: Skip cheese and stir in nutritional yeast for savory, cheesy notes. Add diced avocado after baking.
• Grain swap: Use farro, brown rice, or cauliflower rice (cook separately and adjust moisture).
• Spice it up: Add chipotle in adobo, harissa paste, or a pinch of cayenne for heat.

FAQ

Do I need to cook the quinoa before stuffing the peppers?

Yes. Cooked quinoa ensures a tender, fluffy filling.

Uncooked quinoa won’t hydrate properly inside the peppers and can throw off the texture.

How do I keep the peppers from tipping over?

Use a snug baking dish so they fit tightly. You can also slice a very thin layer off the bottom to create a flat base, being careful not to cut through.

Can I make these ahead?

Absolutely. Assemble up to the point of the final bake, cover, and refrigerate for up to 24 hours.

Add 5–10 extra minutes of baking time if going in cold.

What if I don’t have vegetable broth?

Water is fine. Just season the quinoa a bit more with salt, spices, or a squeeze of lemon to boost flavor.

How do I make this dairy-free?

Skip the cheese or use a dairy-free shredded cheese. A spoonful of nutritional yeast mixed into the filling adds a cheesy, savory note without dairy.

Which bell pepper color is best?

Any color works.

Red, orange, and yellow are sweeter, while green is more earthy and slightly bitter. Choose what you enjoy or mix them for color.

Why is my filling watery?

Your beans or tomatoes may not have been drained well, or the tomatoes released extra liquid. Let the filling cook for an extra minute to evaporate moisture before stuffing.

Can I air-fry these?

Yes, if your peppers fit.

Air-fry at 360°F (182°C) for about 10–12 minutes after stuffing. Par-cook the peppers briefly first to ensure tenderness.

Final Thoughts

Quinoa stuffed bell peppers are the kind of recipe that’s easy to love and hard to mess up. They’re colorful, cozy, and endlessly adaptable to what’s in your fridge.

Make them mild or spicy, cheesy or dairy-free, simple or loaded—whatever suits your mood. With a little prep and smart seasoning, you’ll have a wholesome meal that looks great and tastes even better.
