Stuffed Bell Peppers with Roasted Fall Vegetables bring together sweet bell peppers, caramelized squash, root vegetables, herbs, and grains in one colorful dish. Roasting the vegetables first develops deeper flavor and creates a filling that’s both hearty and satisfying.
The peppers become tender in the oven while the filling stays soft with lightly crisp edges. Fresh herbs add warmth, and a layer of melted cheese creates a golden finish that’s hard to resist.
Why This Recipe Works So Well
Roasted squash and root vegetables add depth and natural sweetness, while cooked grains make the filling satisfying without feeling heavy. Baking everything inside tender bell peppers creates a complete meal with plenty of color, texture, and seasonal ingredients.
Ingredient Notes & Easy Substitutions
- Bell Peppers: Red and yellow peppers add natural sweetness and hold their shape well during baking.
- Squash: Butternut squash and acorn squash both roast beautifully and add texture to the filling.
- Root Vegetables: Carrots and parsnips provide color and subtle sweetness.
- Cooked Grains: Quinoa or rice help bind the filling and make the dish more substantial.
- Fresh Herbs: Sage and thyme complement the roasted vegetables.
- Cheese: Cheddar or mozzarella creates a golden topping, though it can be omitted if preferred.

- Sharp knife

Ingredients
- 4 large bell peppers preferably red or yellow
- 1 cup squash (butternut or acorn) diced
- 1 cup mixed root vegetables (carrots, parsnips) diced
- 2 teaspoons olive oil for roasting
- 1 teaspoon fresh sage chopped

- While the vegetables roast, heat a teaspoon of olive oil in a skillet over medium heat. Add the sage and thyme and cook for about 30 seconds. Stir in the cooked grains, season with salt and pepper, and add the balsamic vinegar if using.
- Once the roasted vegetables have cooled slightly, chop them into smaller pieces and fold them into the grain mixture until evenly combined.
- Spoon the filling into the prepared bell peppers, pressing gently to pack the mixture. Top with shredded cheese if desired.
- Bake for 20 to 25 minutes, or until the peppers are tender and the cheese is melted and lightly golden.
- Remove from the oven, let cool for a few minutes, and serve warm with a garnish of fresh herbs if desired.
