Ingredients
Servings
4
- 4 large bell peppers (any color), tops cut off and seeds removed
- 1 cup quinoa, rinsed
- 2 cups vegetable broth (gluten-free)
- 1 tablespoon olive oil
- 1 small onion, finely chopped
- 2 cloves garlic, minced
- 1 medium zucchini, diced
- 1 medium carrot, peeled and diced
- 1 cup cherry tomatoes, halved
- 1 teaspoon dried oregano
- 1/2 teaspoon smoked paprika
- 1/4 teaspoon black pepper
- Salt to taste
- 1/4 cup fresh parsley, chopped (optional)
- Juice of 1/2 lemon
Instructions
-
Preheat the oven to 375 degrees F (190 degrees C). Lightly grease a baking dish and set aside.
-
In a medium saucepan, bring the gluten-free vegetable broth to a boil. Add the rinsed quinoa, reduce heat to low, cover, and simmer for 15 minutes or until the quinoa is tender and the liquid is absorbed. Remove from heat and let it sit covered for 5 minutes. Fluff with a fork.
-
While the quinoa cooks, heat olive oil in a large skillet over medium heat. Add the chopped onion and garlic, and saute for 3-4 minutes until softened and fragrant.
-
Add the diced zucchini and carrot to the skillet. Cook for another 5 minutes, stirring occasionally, until the vegetables are tender but still vibrant.
-
Add the cherry tomatoes, dried oregano, smoked paprika, black pepper, and salt. Stir well and cook for 2 more minutes to blend flavors. Remove from heat.
-
In a large bowl, combine the cooked quinoa, sauteed vegetables, fresh parsley (if using), and lemon juice. Mix thoroughly.
-
Fill each bell pepper evenly with the quinoa and vegetable mixture. Place the stuffed peppers upright in the prepared baking dish.
-
Cover the dish loosely with aluminum foil and bake for 15 minutes. Remove the foil and bake for an additional 5 minutes to lightly brown the tops.
-
Remove from the oven and let cool for a few minutes before serving. Enjoy warm as a wholesome gluten-free main course.
-
Store leftover stuffed peppers in an airtight container in the refrigerator for up to 3 days. They are also freezer-friendly.
Tips
Allergen Overlap Note
Use gluten-free vegetable broth and check quinoa, spices, and any optional toppings for gluten-free labeling. If cooking in a mixed kitchen, keep the baking dish, skillet, cutting board, and serving spoon away from bread crumbs or regular pasta.
Texture Expectations
The peppers should be tender but still hold their shape, and the quinoa filling should be moist rather than watery. Let the cooked quinoa rest before mixing so it fluffs cleanly and does not turn dense inside the peppers.
Dining With Non-GF Family Note
Serve the gluten-free stuffed peppers before adding bread, rolls, or gluten-containing sides to the table. Use a dedicated spatula or spoon for the peppers so the filling stays safe for gluten-free diners.
Frequently Asked Questions
- Can I make these stuffed peppers ahead?
- Yes. Cook the filling and stuff the peppers up to 1 day ahead, then cover and refrigerate until ready to bake.
- Can I make this grain-free or Whole30-style?
- Quinoa is not grain-free or Whole30. For that style, replace the quinoa with cauliflower rice and confirm every packaged ingredient fits your plan.
- How do I keep the peppers from getting watery?
- Drain any excess liquid from the vegetable skillet and let the quinoa rest before mixing. Bake uncovered for the final few minutes to dry the tops lightly.
Ingredient Replacements
This gluten-free quinoa and vegetable stuffed peppers recipe is versatile and easy to customize for various dietary needs. Consider these ingredient substitutions to adapt the dish while keeping it family-friendly and healthy:
- Quinoa: Swap with cauliflower rice or shredded cooked sweet potatoes for lower-grain versions.
- Vegetable Broth: Use certified gluten-free and dairy-free broth, or opt for homemade broth or herb-infused water for budget-friendly alternatives.
- Olive Oil: Replace with avocado oil or coconut oil to support a different oil preference.
- Vegetables: Substitute zucchini and carrot with seasonal vegetables such as spinach, mushrooms, or bell pepper tops for seasonal or holiday variations.
- Spices: Adjust smoked paprika and oregano to taste or add fresh herbs like thyme, basil, or cilantro for fresh flavor twists.
- Parsley: Omit or swap with cilantro or basil to keep the recipe nut-free and dairy-free while introducing new flavor profiles.
These swaps maintain the recipe's gluten-free, dairy-free, vegan, and family-friendly qualities while accommodating lower-grain preferences—ensuring a wholesome, easy, and quick meal for all tastes and dietary requirements.
Storage and Reheating
Refrigerate cooled stuffed peppers in an airtight container for up to 3 days. Freeze wrapped portions for up to 2 months. Reheat covered in a 350 degrees F (175 degrees C) oven until hot, or microwave individual portions with a loose cover.
