Sliced sweet potatoes in the oven
If you love my Air Fryer Sliced Potatoes, I have a great oven-roasted sweet potato version for you! These slices come out perfectly golden and caramelized with crisp edges and soft, creamy centers.
It’s such an easy recipe, but the result looks and tastes like something special — ideal for weeknights, as a Thanksgiving side, or anytime you want a cozy and beautiful side dish.
I prefer roasting them in the oven for that beautiful, even browning, but you can also make them in the air fryer if yours has enough space (or cook in batches). See recipe FAQs section below to learn how.
Ingredients
- Sweet potatoes - pick medium sized elongated potatoes so that your slices are similarly sized
- Olive oil - or other high heat oil like refined coconut oil or avocado oil
- Seasonings - Coarse kosher salt, garlic powder, ground cumin, and smoked paprika
See recipe card for quantities.
Instructions
- Step 1: Preheat the oven and wash and scrub sweet potatoes, then dry with paper towels.
- Step 2: Use a sharp knife to slice potatoes and place the sweet potato rounds in a mixing bowl (Image 1).
- Step 3: Drizzle olive oil and add salt, and seasonings. Mix well until each potato slice is coated (Image 2). Using your hands is the easiest way.
- Step 4: Place seasoned sweet potato slices in an even layer on a large baking sheet. The slices should not touch each other, if possible (Image 3).
- Step 5: Place in the preheated oven and bake for 30-35 mins until fork tender and lightly carmelized (Image 4).
- Step 6: Transfer to a serving dish and serve hot.
How to Serve Crispy Baked Sweet Potato Slices
- Serve as an appetizer with a dipping sauce like my Dill Aioli and Gochujang Aioli dip.
- As part of a weeknight dinner with my Buffalo Chicken Tenders or with my Air Fryer Chicken Kebabs or Pork Kebabs. You can serve it family style right on the baking sheet for easy cleanup!
- As a holiday side - arranged beautifully on a platter - alongside my Ricotta Mac and Cheese, Sourdough Stuffing, and Butternut Feta Salad.
Storage and Reheating Tips
- STORE: Let the potato slices cool completely, and store up to 4 days in an airtight container in the fridge.
- REHEAT on a baking sheet in a 400 degree oven for 10 minutes or until heated through.
Tips & Tricks
- When choosing sweet potatoes for this recipe, pick ones that are similar in size. That way the slices will be uniform and will cook evenly.
- There is no need to peel the sweet potatoes before slicing, but you can if that's your preference.
- Pat the sweet potatoes dry after scrubbing to avoid excess moisture while cooking.
- Slice potatoes into ⅓ - ½-inch thick rounds
- Make sure all the potato slices are evenly coated in oil before placing on the baking sheet.
- Don’t overlap potatoes too much on the sheet pan or they won’t crisp as well when cooking.
- Feel free to play around with the herbs and seasoning variations to create all sorts of great flavors. You can add smoked paprika for depth or a half teaspoon of cayenne for a little kick, or use fresh herbs like rosemary and thyme for an earthy, more savory flavor.
Recipe FAQs
Make sure to spread the slices out in a single layer without overlapping. Crowding the pan traps steam and prevents caramelization and crisping.
Yes! Cook at 375°F for about 15-18 minutes in one single layer, until golden and tender. If your air fryer is on the smaller side, cook the potatoes in batches and keep the already roasted ones in the warm oven.
