The marriage of roasted vegetables with protein-rich quinoa transforms these humble peppers into sophisticated entrées that I’m confident will elevate your dining experience.
There’s an art to achieving the perfect texture and seasoning in this dish, and I’ll share my carefully tested techniques for bringing out the best in each ingredient.
Recipe
Roasted Vegetable and Quinoa Stuffed Peppers deliver a satisfying blend of Mediterranean flavors while providing essential nutrients in a completely plant-based format. The combination of protein-rich quinoa and tender roasted vegetables creates a filling that’s both wholesome and delicious, all nestled inside sweet bell peppers.
This vegan dish transforms everyday ingredients into an elegant main course that’s perfect for both weeknight dinners and special occasions. The roasting process brings out the natural sweetness of the vegetables, while the quinoa adds a pleasant nutty flavor and hearty texture that makes this meal both nutritious and satisfying.
- 4 large bell peppers
- 1 cup quinoa
- 2 cups vegetable broth
- 1 zucchini
- 1 eggplant
- 1 red onion
- 3 garlic cloves
- 2 tablespoons olive oil
- 1 can diced tomatoes (14.5 oz)
- 1 teaspoon dried oregano
- 1 teaspoon dried basil
- 1/2 teaspoon smoked paprika
- Salt and pepper to taste
Preheat oven to 400°F. Rinse quinoa and cook in vegetable broth for 15-20 minutes until fluffy. While quinoa cooks, dice zucchini, eggplant, and onion, then mince garlic. Toss vegetables with olive oil and roast on a baking sheet for 20 minutes.
Cut peppers in half lengthwise, remove seeds and membranes. Combine cooked quinoa with roasted vegetables, diced tomatoes, and seasonings. Fill pepper halves with mixture, place in baking dish, cover with foil, and bake 30-35 minutes until peppers are tender.
For optimal results, select bell peppers that have relatively flat bottoms so they can stand upright when halved. If preparing ahead, the quinoa-vegetable filling can be made up to 24 hours in advance and stored in the refrigerator.
To achieve a crispy top, remove foil during the final 10 minutes of baking and switch oven to broil setting. The stuffed peppers will keep well in an airtight container in the refrigerator for up to 4 days.
Step-By-Step Cooking Instructions
You’ll begin this culinary journey by preheating your oven and gathering your fresh ingredients, with special attention to selecting firm, colorful bell peppers that will serve as your edible vessels.
After cooking your quinoa to fluffy perfection in seasoned vegetable broth, you’ll proceed to roast your medley of diced vegetables until they’re caramelized and aromatic, combining them with the cooked quinoa and vibrant seasonings.
Finally, you’ll fill each pepper half with your fragrant mixture, allowing them to bake until tender while their flavors meld beautifully together, creating a wholesome, satisfying meal.
Step 1. Preheat and Prepare Ingredients
Begin your culinary journey by preheating your oven to 400°F (200°C) while gathering the fresh produce and pantry staples. You’ll need four large, firm bell peppers that can stand upright when halved, along with fresh zucchini, eggplant, and red onion for the aromatic vegetable medley.
While your oven comes to temperature, rinse the quinoa thoroughly under cold water until the water runs clear, removing any bitter saponins. Prepare your mise en place by dicing the zucchini and eggplant into uniform 1/2-inch cubes, finely chopping the red onion, and mincing the garlic cloves. This consistent size ensures even cooking and optimal texture in your final dish.
Next, slice your bell peppers lengthwise, carefully removing the seeds and membranes while keeping the stems intact for presentation. Position the peppers on your cutting board to ensure they’ll sit steadily in your baking dish.
Measure out your dried herbs and spices, keeping them within arm’s reach. You’ll also want to open your can of diced tomatoes and have your vegetable broth ready for cooking the quinoa.
Step 2. Cook Quinoa in Broth
Once your mise en place is ready, combine 1 cup of rinsed quinoa with 2 cups of vegetable broth in a medium saucepan, ensuring the liquid covers the grains by about an inch.
Place the saucepan over medium-high heat and bring the mixture to a vigorous boil, watching carefully to prevent any overflow. Once boiling, reduce the heat to low and cover the pan with a tight-fitting lid.
Let the quinoa simmer gently for 15-20 minutes, resisting the urge to lift the lid, as this releases essential steam.
You’ll notice the quinoa is done when you see tiny spiral-like threads (the germ) separating from and curling around the grains.
Remove the pan from heat and let it stand, covered, for an additional 5 minutes to allow the quinoa to absorb any remaining liquid and become light and fluffy.
Using a fork, gently fluff the quinoa to separate the grains and release any trapped steam.
This cooking method ensures your quinoa maintains its distinct texture while absorbing the rich flavor of the vegetable broth, creating an ideal base for your pepper stuffing.
Step 3. Roast Mixed Vegetables
A medley of fresh vegetables awaits transformation through the caramelizing magic of high-heat roasting.
Begin by dicing your zucchini and eggplant into uniform 1/2-inch cubes, ensuring they’ll cook evenly. Finely chop the red onion and mince the garlic cloves until they release their aromatic oils.
Place your prepared vegetables on a large rimmed baking sheet, keeping them in a single layer to prevent steaming. Drizzle them with two tablespoons of olive oil, then use your hands to toss them gently until they’re evenly coated.
You’ll want to ensure each piece has a light sheen of oil to promote proper caramelization.
Slide the baking sheet into your preheated 400°F oven and set your timer for 20 minutes. At the halfway mark, remove the pan and give the vegetables a quick toss with a spatula.
You’ll notice they’re beginning to brown at the edges – that’s exactly what you want. Return them to the oven and continue roasting until they’re tender and golden brown, with slightly crispy edges.
They’ll have a concentrated, sweet flavor that’ll enhance your stuffed peppers beautifully.
Step 4. Fill Peppers With Mixture
Now that your roasted vegetables have developed their rich, caramelized flavors, you’ll combine them with the prepared quinoa and seasonings to create the filling for your peppers.
In a large mixing bowl, gently fold the roasted zucchini, eggplant, onion, and garlic into the fluffy quinoa, ensuring even distribution throughout the mixture. Add the diced tomatoes, dried oregano, basil, and smoked paprika, stirring carefully to maintain the vegetables’ integrity while incorporating the seasonings thoroughly.
Take your halved bell peppers and position them cut-side up in a well-oiled baking dish, arranging them so they’re nestled closely together to prevent tipping.
Using a spoon, fill each pepper cavity generously with the quinoa-vegetable mixture, pressing down gently to ensure the filling is compact but not crushed. You’ll want to mound the mixture slightly above the pepper’s rim, as it will settle during baking.
Cover the dish tightly with aluminum foil, ensuring it doesn’t touch the filling. The foil creates a mini steam chamber that’ll help the peppers cook evenly while keeping the filling moist.
Step 5. Bake and Serve Hot
With the filled peppers nestled in their baking dish and covered with foil, place them in your preheated 400°F oven for 30-35 minutes until the peppers become tender yet maintain their structural integrity.
You’ll know they’re perfectly done when a knife easily pierces the pepper walls while they still hold their shape.
For an enticing golden-brown finish, remove the foil during the final 10 minutes of baking and switch to your oven’s broil setting.
Keep a watchful eye during this step to prevent any unwanted charring of the quinoa-vegetable filling.
Once done, let the peppers rest for 5 minutes before serving to allow the flavors to settle and prevent burning your guests.
Present your stuffed peppers on warmed plates, garnished with fresh herbs if desired.
You’ll notice the peppers have developed a beautiful caramelized exterior while retaining their vibrant color.
The filling should be steaming hot, with the quinoa and roasted vegetables creating an appealing medley of textures.
For added visual appeal and flavor dimension, drizzle each pepper with a touch of extra virgin olive oil just before serving.
