There’s nothing quite like the sweet, savory balance of a perfectly roasted sweet potato—golden edges, fluffy centers, and that natural caramelization that makes each bite better than the last. But add garlic, a few warm spices, and a hint of herbs? Now you’re in side dish heaven. These Garlic Roasted Sweet Potatoes are easy to make, full of bold, comforting flavors, and ideal for everything from weeknight dinners to holiday spreads.
This recipe turns humble sweet potatoes into something bold, aromatic, and unforgettable. They’re crispy enough to satisfy your fry cravings, sweet enough to please picky eaters, and hearty enough to stand alone as a meal base or salad topper. And all you need is a sheet pan, a few pantry staples, and about 35 minutes from start to finish.
Why Roast Sweet Potatoes?
Roasting is hands-down the best way to bring out the natural sweetness of sweet potatoes while also getting that crispy exterior. It intensifies the sugars inside, balances the starch, and gives you a texture that’s fluffy on the inside and golden on the outside.
Roasting also:
- Requires minimal effort
- Is easy to scale up for meal prep or crowd-pleasing sides
- Pairs well with both sweet and savory flavors
- Works with a variety of spices and seasonings
And when garlic gets in on the action? You get those deep, nutty, toasty notes that take this dish to another level.
Choosing the Best Sweet Potatoes
For the best flavor and texture, choose:
- Firm sweet potatoes with smooth skin (no bruising or soft spots)
- Medium-sized for easier, more uniform cuts
- Orange-fleshed varieties like Beauregard or Garnet—they’re naturally sweeter and roast beautifully
Avoid white or purple varieties for this recipe unless you want a starchier or earthier final dish.
How to Cut Sweet Potatoes for Roasting
Uniform cutting is key to even roasting. For this recipe, we recommend:
- 1-inch cubes or half-moons: Large enough to stay fluffy inside, small enough to get crispy
- Leave the skin on for extra fiber and a little extra crispiness (just scrub well)
- Cut everything as evenly as possible so nothing burns before the rest finishes cooking
Want them extra crispy? Cut into smaller pieces and roast at a slightly higher heat—more on that below.
Garlic: Raw vs. Roasted Flavor
Garlic adds a bold, aromatic backbone to this dish—but how and when you add it matters:
- Tossing raw garlic with sweet potatoes can risk burning, which gives a bitter taste
- Solution: Toss half the garlic with the potatoes before roasting, then add the rest in the final 5 minutes
- Alternatively, you can use garlic powder to infuse flavor without the risk of burning
If you’re a garlic lover, do both—just make sure to protect those fresh minced bits from overcooking.

Ingredients
- 2 medium sweet potatoes (about 1.5 pounds), scrubbed and cut into 1-inch cubes
- 2 tablespoons olive oil
- 3–4 garlic cloves, minced (divided)
- 1 teaspoon garlic powder
- ½ teaspoon smoked paprika (optional)
- ½ teaspoon dried thyme or rosemary
- ½ teaspoon sea salt (or to taste)
- ¼ teaspoon black pepper
- Optional: fresh parsley or chives for garnish
Instructions
- Preheat Oven
Preheat your oven to 425°F (220°C). Line a baking sheet with parchment paper or lightly grease it for easy cleanup. - Toss Sweet Potatoes
In a large bowl, combine sweet potatoes with olive oil, half the minced garlic, garlic powder, paprika, thyme, salt, and pepper. Toss until evenly coated. - Arrange and Roast
Spread the sweet potatoes in a single layer on the prepared baking sheet. Don’t overcrowd—use two sheets if necessary. - Roast First Round
Roast for 20 minutes, then remove from oven, toss the potatoes, and add the remaining minced garlic. Return to oven. - Finish Roasting
Roast another 10–15 minutes, or until the edges are golden and crisp and the inside is fork-tender. - Garnish and Serve
Transfer to a serving bowl and sprinkle with fresh parsley, chives, or a squeeze of lemon juice if desired.
Tips for Maximum Crispiness
- Preheat the pan in the oven before adding potatoes for better sear
- Use enough oil to coat each piece but not pool on the pan
- Don’t overcrowd the baking sheet—airflow is key
- Roast at a high heat (425°F or higher) for caramelization
Storage and Reheating
- Refrigerate: Store leftovers in an airtight container for up to 4 days
- Reheat: Warm in a 375°F oven or Air Fryer for 5–10 minutes to restore crispiness
- Don’t microwave unless you’re okay with soft textures
Great for meal prep—just reheat and pair with a protein or toss into salads and bowls.
Serving Suggestions
These garlic roasted sweet potatoes pair with just about anything:
