Tips & Variations
- For extra sweetness, add a splash more maple syrup before the final bake.
- Try swapping sweet potatoes with regular potatoes or adding carrots for variety.
- If fresh herbs aren’t available, increase the dried herbs slightly for a stronger flavor.
- Use parchment paper instead of foil for easier cleanup and slight crisping of vegetables.
Storage
Store leftovers in an airtight container in the refrigerator for up to 3 days. Reheat in the oven or a skillet to maintain crisp edges; microwaving works but may soften the texture.

Description
Delicious roasted sweet potatoes with caramelized onions, infused with a blend of dried and fresh herbs, garlic, and a touch of maple syrup for a perfect balance of sweetness and savory flavors. This easy-to-make side dish is roasted in the oven to achieve tender, golden, and slightly crispy vegetables.
Ingredients
Vegetables
- 2.5 pounds sweet potatoes, peeled and cut into 1-inch pieces
- 1 onion, cut into 1-inch pieces
- 2 cloves garlic, peeled and minced
Herbs & Seasonings
- 1 tablespoon dried mixed herbs
- 1 teaspoon fresh herbs (such as thyme, parsley, or rosemary), finely chopped
- 1/2 teaspoon salt
- 1/2 teaspoon ground black pepper
Others
- 2 tablespoons olive oil
- 1 tablespoon maple syrup
Instructions
- Preheat the oven: Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius) to ensure it’s hot and ready for roasting the vegetables evenly.
- Prepare the vegetables: Peel the sweet potatoes and cut them into 1-inch pieces. Peel and cut the onion into similar-sized chunks for even cooking. Mince the garlic cloves finely. Chop the fresh herbs you’ve chosen, such as thyme, parsley, or rosemary.
- Mix the ingredients: In a large bowl, combine the sweet potatoes, onion, minced garlic, dried mixed herbs, chopped fresh herbs, olive oil, maple syrup, salt, and ground black pepper. Toss everything together until the vegetables are evenly coated with the oil, herbs, and seasoning.
- Transfer to baking dish: Place the coated vegetables into a 13×9 inch rimmed baking dish. Cover the dish tightly with aluminum foil or a baking dish cover to help the vegetables steam and cook through.
- Bake: Bake covered in the preheated oven for about 30 minutes, allowing the sweet potatoes to cook until tender.
- Uncover and brown: Remove the foil and bake for an additional 5 to 10 minutes. This step helps the sweet potatoes and onions to turn golden and slightly crispy. For a more intense roasted flavor, optionally switch on the broiler during the last 5 minutes and watch carefully to avoid burning.
- Garnish and serve: Once roasted to your liking, garnish with extra fresh herbs if desired. Serve hot as a flavorful side dish.
Notes
- You can substitute maple syrup with honey or brown sugar if preferred.
- For a spicier twist, add a pinch of cayenne pepper or smoked paprika to the seasoning mix.
- Use a high-quality olive oil for better flavor and browning.
- Make sure to cut the sweet potatoes and onions into uniform pieces to ensure even roasting.
- Broiling is optional but adds a nice charred flavor. Keep a close eye to prevent burning.
