Quick answer: Quinoa stuffed bell peppers are made by filling halved bell peppers with fully cooked quinoa, sautéed onion and garlic, tomato sauce, herbs, and optional cheese, then baking at 375°F for 30–35 minutes until tender but still structured. They’re a healthy, high-protein vegetarian dinner that’s naturally gluten-free and ideal for meal prep.
Why it works: Quinoa absorbs flavor while staying light and fluffy. Baking softens the peppers without collapsing them, creating a balanced, plant-based meal with protein, fiber, and vegetables in every bite.
This recipe follows Jamie Oliver’s philosophy of simple ingredients, bold flavor, and practical home cooking. It is inspired by that approach but is not an official Jamie Oliver recipe.
These quinoa stuffed bell peppers are baked, not boiled, helping the peppers retain their structure while the filling stays fluffy and cohesive. Packed with quinoa, sautéed onion and garlic, tomato sauce, herbs, and optional cheese, this dish delivers balanced nutrition without sacrificing flavor.
If you’re looking for a high-protein, gluten-free, plant-based meal that works for busy weeknights or structured meal prep, this recipe is a reliable choice. Everything bakes in one dish, cleanup is minimal, and the recipe scales easily.
Ingredients
- 4 large bell peppers, halved and seeds removed
- 1 cup uncooked quinoa
- 2 cups vegetable broth (preferred for depth of flavor)
- 1 tablespoon olive oil
- 1 small onion, finely diced
- 2 cloves garlic, minced
- 1 cup crushed tomato sauce
- ½ teaspoon dried oregano or basil
- ¼ cup chopped parsley
- ½ cup shredded cheese (optional or vegan alternative)
- Salt and freshly ground black pepper
How to Make Quinoa Stuffed Bell Peppers
1. Preheat the oven: Set oven to 375°F (190°C). Lightly grease a baking dish large enough to hold peppers upright.
2. Cook the quinoa properly: Rinse quinoa thoroughly to remove bitterness. Bring broth to a boil, add quinoa, reduce to low, cover, and simmer for 15 minutes. Remove from heat and let steam 5 minutes before fluffing. Properly cooked quinoa should be tender but not mushy.
3. Build flavor: Warm olive oil in a pan. Add onion and cook 4–5 minutes until soft. Add garlic and cook 30 seconds until fragrant without browning.
4. Prepare the filling: Stir quinoa into the pan with tomato sauce, herbs, salt, and pepper. Simmer 2–3 minutes. Remove from heat and fold in parsley and optional cheese.
5. Stuff the peppers: Arrange halved bell peppers cut-side up. Spoon filling firmly but without compacting.
6. Bake in stages: Cover loosely with foil and bake 20 minutes. Remove foil and bake another 10–15 minutes until tender but structured.
Let rest 5 minutes before serving.
Why Quinoa Is Ideal for Stuffed Peppers
Quinoa is one of the few plant-based foods considered a complete protein, meaning it contains all nine essential amino acids. This makes quinoa stuffed bell peppers more nutritionally balanced than rice-based versions.
- Naturally gluten-free
- High in fiber
- Rich in magnesium and iron
- Lower glycemic impact than white rice
Because quinoa remains fluffy and slightly nutty after baking, the final texture stays balanced rather than dense.
Expert Tips
- Do not overcook quinoa — it should remain fluffy.
- Choose firm bell peppers with flat bottoms.
- Cover during early baking to soften evenly.
- Season each layer for best flavor.
- Allow resting time for structure.
Flavor Variations
- Vegan: Omit cheese or use plant-based alternatives.
- Mexican-style: Add black beans, cumin, chili powder.
- Mediterranean: Add feta, olives, lemon zest.
- Extra protein: Add chickpeas or lentils.
Make Ahead and Storage
- Refrigerate assembled (unbaked) up to 24 hours.
- Store baked leftovers 3–4 days.
- Freeze fully baked peppers up to 2 months.
- Reheat at 350°F until warmed through.
