Preheat the oven to 400 degrees F (200 degrees C).
Peel and cut the Sweet Potato (2.5 pound) and Onion (1) into 1-inch pieces.
Peel and mince the Garlic (2 clove).
Finely chop the Fresh Herbs (1 teaspoon). You can use herbs like thyme, parsley, rosemary, etc.
In a large bowl, combine the sweet potatoes, onion, garlic, Dried Mixed Herbs (1 tablespoon), fresh herbs, Olive Oil (2 tablespoon), Maple Syrup (1 tablespoon), and Salt (1/2 teaspoon) and Ground Black Pepper (1/2 teaspoon).
Mix it all to combine, so that the potatoes are evenly coated by all the ingredients.
Transfer all the ingredients into a 13x9 inch rimmed baking dish. Cover the baking dish with aluminum foil or a cover.
Bake for about 30 minutes, until the potatoes are cooked through.
Uncover and cook for an additional 5-10 minutes, until the sweet potatoes and the onions turn golden. If you want a more roasted/charred flavor, you can turn on the broiler during the last 5 minutes of baking.
Garnish with more fresh herbs and serve hot.
