Ingredients
Servings
4
- 4 large bell peppers (any color, tops cut off and seeds removed)
- 1 cup quinoa, rinsed
- 2 cups vegetable broth or water
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 medium zucchini, diced
- 1 cup mushrooms, diced
- 1 cup cherry tomatoes, halved
- 1 cup fresh spinach, chopped
- 2 tablespoons olive oil, divided
- 1 teaspoon smoked paprika
- 1/2 teaspoon ground cumin
- Salt and freshly ground black pepper, to taste
- 1/4 cup fresh parsley, chopped (for stuffing)
- 1/4 cup fresh basil, chopped (for stuffing)
- 1 cup raw cashews (soaked in warm water for 2+ hours or boiled 15 minutes)
- 1/3 cup water (adjust for desired creaminess)
- 2 tablespoons fresh lemon juice
- 1 garlic clove
- 1/4 cup fresh parsley
- 1/4 cup fresh basil
- 1/4 teaspoon salt
- Freshly ground black pepper, to taste
Instructions
-
Preheat the oven to 375°F (190°C). Lightly grease a baking dish large enough to hold the bell peppers upright.
-
Place the hollowed bell peppers cut side up in the prepared baking dish.
-
In a medium saucepan, bring the vegetable broth (or water) to a boil. Add quinoa, reduce heat to low, cover, and simmer for 15 minutes or until the quinoa is fluffy and the liquid is absorbed. Remove from heat and fluff with a fork.
-
While the quinoa cooks, heat 1 tablespoon olive oil in a large skillet over medium heat. Add chopped onion and minced garlic; sauté for 3-4 minutes until translucent and fragrant.
-
Add diced zucchini, mushrooms, and cherry tomatoes to the skillet. Cook for about 7-8 minutes, stirring occasionally, until vegetables are tender and tomatoes start to break down.
-
Stir in chopped spinach, smoked paprika, cumin, salt, and pepper. Cook for another 2 minutes until the spinach wilts.
-
Remove the skillet from heat and combine the cooked quinoa, sautéed vegetables, and fresh herbs (parsley and basil). Mix well to combine the filling evenly.
-
Fill each bell pepper generously with the quinoa and vegetable mixture, pressing down lightly to pack.
-
Drizzle the remaining 1 tablespoon olive oil over the stuffed peppers.
-
Cover the baking dish loosely with foil and bake in the preheated oven for 30 minutes.
-
While the peppers bake, prepare the cashew herb sauce: Drain soaked cashews and place them in a high-speed blender with water, lemon juice, garlic, parsley, basil, salt, and pepper.
-
Blend until completely smooth and creamy, adding more water as needed to reach a sauce consistency.
-
Remove the foil from the peppers and bake uncovered for an additional 5-10 minutes to allow the tops to brown slightly, if desired.
-
Serve the stuffed bell peppers warm, topped generously with the cashew herb sauce.
-
Garnish with additional fresh herbs if desired and enjoy your comforting, gluten-free, vegan main course!

Allergen Overlap Note
Our gluten-free recipes, spanning categories like Breakfast, Lunch, Dinner, Desserts, Snacks, Soups & Salads, Gluten-Free Baking, and more, are crafted to exclude gluten-containing ingredients. However, beware of allergen overlap risks, especially if you follow diets such as dairyfree, nutfree, vegan, or paleo.
Many Freeflourish recipes include helpful tags like dairyfree, nutfree, vegan, and grainfree allowing you to quickly identify safe choices. Although ingredients minimize allergens, some cross-contamination can occur in sourcing or shared kitchens.
To ensure safe meal prep:
- Use certified gluten-free grains and flours to avoid hidden gluten sources.
- Review all labels for gluten-containing additives or processing aids.
- Keep separate cooking tools and surfaces for gluten-free cooking.
- Verify substitutions meet your allergen requirements.

Texture Expectations
Understanding texture is key to enjoying gluten-free dishes like these vegan stuffed bell peppers. Without traditional gluten, alternative grains and ingredients provide structure and mouthfeel.
The quinoa offers a naturally light, fluffy, and slightly chewy texture that pairs beautifully with tender sautéed vegetables. The bell peppers roast to a soft yet firm bite, holding their shape as edible vessels without becoming mushy. The dairy-free cashew herb sauce adds a silky, creamy finish, enriching the dish's moistness and flavor.
You can expect a pleasing medley of textures: tender but sturdy peppers, fluffy-rich quinoa, tender vegetables with a slight bite, and smooth cashew creaminess. These contrasting textures create a comforting, satisfying gluten-free main course experience.
Note that gluten-free stuffed dishes may vary slightly in firmness compared to gluten-containing versions. Adjust cooking times or vegetable sizes to fine-tune texture according to your preference.
Dining With Non Gf Family Note
Preparing gluten-free meals in a household with mixed diets can be simple with mindful cross-contamination prevention and clear communication.
- Use Separate Tools and Surfaces: Dedicate cutting boards, utensils, and cookware for gluten-free preparations. Thoroughly clean all surfaces and tools before and after meal prep.
- Manage Shared Appliances: Use toaster bags or separate appliances for gluten-free cooking to avoid gluten crumbs from shared devices like grills or toasters.
- Store Ingredients Separately: Label and keep gluten-containing and gluten-free ingredients apart to prevent accidental cross-contact.
- Choose Naturally Gluten-Free Meals: Opt for recipes in categories like Breakfast, Lunch, Dinner, Desserts, and Snacks tagged as glutenfree, familyfriendly, and easy for smooth mealtime success.
- Communicate with Family: Ensure everyone understands gluten-free precautions and knows which foods are safe.
- Label Gluten-Free Foods at the Table: Keep gluten-free dishes separate and clearly marked to avoid confusion during meals.
- Include Everyone in Cooking: Involve non-gluten-free family members in gluten-free meal prep to foster awareness, empathy, and enjoyable shared meals.
These strategies foster a safe, inclusive, and flavorful dining experience for your family-friendly gluten-free lifestyle.
