The idea of hollowing out a vegetable and filling it with a flavorful mixture is as practical as it is delicious. In this version, we bring a distinctly autumnal charm by featuring roasted winter squash and quinoa, two staples of the cold-weather pantry.

Winter squash adds natural sweetness and a velvety texture, while quinoa provides a light, protein-rich balance. The combination makes for a filling that’s both nutrient-dense and deeply satisfying.

2 cloves garlic, minced
2 tbsp olive oil
1 tsp ground cumin
½ tsp smoked paprika
½ tsp cinnamon
1 tbsp soy sauce or tamari
2 tbsp chopped fresh parsley (plus more for garnish)
¼ cup toasted pumpkin seeds or chopped walnuts
Salt and freshly ground pepper, to taste

Optional Add-ins:

½ cup chopped spinach or kale for added greens
¼ cup dried cranberries or chopped dates for a touch of sweetness

Baking dish or oven-safe tray

Step-by-Step Instructions

Step 1: Prepare the Bell Peppers

Preheat the oven to 190°C (375°F). Slice off the tops of the bell peppers and remove the seeds and membranes. Lightly brush the outer skins with olive oil and place them in a baking dish. Roast for about 15 minutes while you prepare the filling. This helps soften the peppers slightly and enhances their sweetness.

Step 2: Roast the Winter Squash

Spread the cubed squash on a baking sheet, drizzle with 1 tablespoon of olive oil, and season with salt and pepper. Roast in the preheated oven for 20–25 minutes, or until tender and golden around the edges. Set aside to cool slightly.

Step 3: Prepare the Filling

In a large skillet over medium heat, warm the remaining 1 tablespoon of olive oil. Sauté the diced onion for 4–5 minutes until translucent. Add minced garlic, cumin, paprika, and cinnamon, stirring for about 1 minute until fragrant.

Add the roasted squash and cooked quinoa to the pan. Stir in soy sauce (or tamari), parsley, and pumpkin seeds. Mix everything until well combined and heated through. Taste and adjust seasoning with salt, pepper, or a squeeze of lemon juice for brightness.

Step 4: Stuff the Peppers

Spoon the quinoa and squash mixture generously into each roasted bell pepper. Pack gently so they’re well-filled but not overflowing. Arrange them upright in the baking dish. If desired, sprinkle a little nutritional yeast or vegan cheese on top.

Step 5: Bake to Perfection

Cover the dish loosely with foil and bake for 20–25 minutes, until the peppers are tender and the filling is hot throughout. For a golden top, uncover during the last 5 minutes of baking.

Once done, remove from the oven and let cool for a few minutes before serving. Garnish with extra parsley or a drizzle of olive oil.

Expert Tips & Troubleshooting

Choose firm peppers: They should be sturdy enough to hold the filling after roasting.
Don’t overcook the squash: Keep it slightly firm so it holds its shape in the mixture.
Make ahead: You can prepare the filling a day in advance and assemble just before baking.
Avoid soggy results: Drain cooked quinoa well to prevent excess moisture.
Flavor boosters: Add a spoonful of tahini or a dash of balsamic glaze for a richer flavor.

Serving Suggestions

As a main dish: Pair with a simple green salad or roasted Brussels sprouts.
As a side: Serve alongside lentil stew, baked tofu, or a creamy soup.
For gatherings: Arrange on a platter and drizzle with pomegranate seeds for a festive touch.
For extra richness: Top with a spoonful of yogurt or cashew cream before serving.

Variations & Customizations

Mediterranean Style: Add olives, sun-dried tomatoes, and fresh basil.
Spicy Kick: Mix in a teaspoon of harissa or chili flakes.
Protein Boost: Add chickpeas or lentils for an extra plant-based punch.
Nut-Free Version: Replace pumpkin seeds with toasted sunflower seeds.
Sweet Touch: Include diced roasted apple or pear for a subtle hint of sweetness.

Make-Ahead & Storage Tips

Refrigeration: Store leftovers in an airtight container for up to 4 days.
Freezing: Cool completely, wrap individually in foil, and freeze for up to 2 months. Reheat in the oven until warmed through.
Reheating: Warm gently in the oven at 180°C (350°F) for 10–15 minutes, or microwave for 2–3 minutes per pepper.

FAQ

Do I need to pre-roast the peppers?
It’s optional, but pre-roasting gives them a sweeter flavor and softer texture.

Can I make this recipe oil-free?
Absolutely. Just roast and sauté using vegetable broth instead of oil.
