Roasted Sweet Potatoes and Onions bring out the savory side of sweet potatoes with garlic and herbs. Simple to make and full of flavor.
Roasted Sweet Potatoes and Onions are a game-changer when it comes to healthy and flavorful side dishes. I’m all about making nutritious meals that not only fuel my body but also taste absolutely delicious. While sweet potatoes are naturally sweet, I love adding savory touches to them, especially when pairing them with a main course like roast chicken. With the addition of aromatic onions, garlic, and fresh herbs, this recipe brings out the natural earthiness of sweet potatoes in a way that’s downright satisfying.
What makes this recipe even better is the versatility. The onions bring a rich sweetness when roasted, while the garlic and fresh herbs infuse the potatoes with amazing flavors. If you’re looking to make it even more indulgent, a sprinkle of grated Parmesan cheese adds a nutty, cheesy note that perfectly complements the caramelized potatoes. A quick broil at the end of roasting ensures that the potatoes get a gorgeous, crispy finish. This dish is so flavorful on its own, you might just find yourself enjoying it as a main course rather than just a side.
Ingredients
2 ½ lbs sweet potatoes, peeled and cut into 1 - 1 ½ pieces
1 large onion, peeled and cut into ½-1 inch pieces
2-3 garlic cloves, minced
1 teaspoon dry herbs, optional (such as rosemary, thyme, parsley, oregano, etc.)
1 - 2 Tablespoons fresh herbs, finely chopped (whatever you prefer - thyme, parsley, rosemary, etc.)
2-3 Tablespoons oil (avocado, olive, vegetable, etc.)
1 Tablespoon maple syrup
½ teaspoon salt, ground black pepper, to taste
How To Make Roasted Sweet Potatoes and Onions
Preheat the oven to 400 degrees Fahrenheit.
Peel and cut the sweet potatoes and onion. 
Peel and mince the garlic and finely chop the fresh herbs.
In a large bowl, combine the sweet potatoes, onion, garlic, dry and fresh herbs, oil, maple syrup and salt and ground black pepper. 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 and bake for about 30 minutes, until the potatoes are cooked through.
You can also add some shredded cheese to the top of the vegetables, if you'd like.
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.

More cheese? Am I missing cheese as an ingredient? What kind? Thanks
Hi Robin,
I didn't add any cheese, that was just a suggestion that cheese is an option if you want to add it.
