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 degrees F. 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!
Tips
Allergen Overlap Note
Check every packaged ingredient for certified gluten-free status, especially spices, broths, sauces, seed products, and baking staples. Use clean prep surfaces, dedicated utensils, and fresh parchment or cookware when preparing vegan stuffed bell peppers with cashew herb sauce for someone with celiac disease.
Texture Expectations
Keep the filling moist but not wet so the peppers bake evenly. Rest the filled peppers for 5 minutes before baking so filling settles around the center.
Dining With Non-GF Family Note
Plate peppers first on dedicated gluten-free dishware and add the cashew sauce after reheating so mixed-diet family members can control sauce portions.
