Ingredients
Roasted Sweet Potatoes
- 2 lb sweet potatoes peeled or well-scrubbed and dried
- 2 tbsp olive oil
- 1.25 tsp kosher salt plus more to taste
- 0.5 tsp black pepper freshly ground
- 1 tsp smoked paprika
- 1 tsp garlic powder or 2 cloves fresh garlic, minced
- 0.5 tsp dried thyme or 1 to 1 1/2 tsp chopped fresh thyme or rosemary
- 1 tbsp cornstarch optional; or arrowroot
- Pinch crushed red pepper flakes optional
Finish (optional)
- 1 tsp lemon juice or apple cider vinegar
- 1 tbsp parsley chopped; or chives
Instructions
Step-by-Step Instructions
- Place a large rimmed sheet pan on the middle rack and preheat the oven to 425 b0F (220 b0C). A hot pan jump-starts caramelization and helps keep the bottoms crisp.
- Slice into 3/4-inch cubes or wedges. Aim for uniform pieces so they cook at the same rate. Pat very dry to remove surface moisture.
- Toss the sweet potatoes with olive oil, salt, pepper, smoked paprika, garlic, and thyme until every piece is glossy. If using cornstarch, sprinkle it over and toss again to lightly coat.
- Carefully remove the preheated pan and spread the potatoes in a single layer with space between pieces. For cubes, place one flat side down to maximize browning. Avoid parchment if you want the crispest edges.
- Roast 20 minutes undisturbed, then flip and roast 10 to 15 minutes more until deeply golden and tender. If using convection, roast at 400 b0F and start checking at 25 minutes.
- Toss with a squeeze of lemon or a splash of apple cider vinegar and fresh herbs. Taste and adjust salt. Serve hot.

Step-by-Step Instructions to Make Savory Roasted Sweet Potatoes
Preheat the oven and pan
Place a large rimmed sheet pan on the middle rack and preheat the oven to 425°F (220°C). A hot pan jump-starts caramelization and helps keep the bottoms crisp.
Cut the sweet potatoes evenly
Slice into 3/4-inch cubes or wedges. Aim for uniform pieces so they cook at the same rate. Pat very dry to remove surface moisture.
Season thoroughly
Toss the sweet potatoes with olive oil, salt, pepper, smoked paprika, garlic, and thyme until every piece is glossy. If using cornstarch, sprinkle it over and toss again to lightly coat.
Load the hot pan
Carefully remove the preheated pan and spread the potatoes in a single layer with space between pieces. For cubes, place one flat side down to maximize browning. Avoid parchment if you want the crispest edges.
Roast to caramelized perfection
Roast 20 minutes undisturbed, then flip and roast 10 to 15 minutes more until deeply golden and tender. If using convection, roast at 400°F and start checking at 25 minutes.
Finish and serve
Toss with a squeeze of lemon or a splash of apple cider vinegar and fresh herbs. Taste and adjust salt. Serve hot.
Tips for Success
- Preheat the sheet pan so the potatoes sizzle on contact.
- Do not overcrowd. Give each piece breathing room to crisp rather than steam.
- Dry your potatoes after washing. Moisture is the enemy of crisp edges.
- Toss oil first, then cornstarch so it adheres in a thin, even layer.
- Use a light-colored aluminum sheet pan for the most even browning.
- Flavor balance: a tiny hit of acid at the end makes the savory notes pop.

Storage & Reheating Instructions
Cool completely, then store in an airtight container up to 4 days in the fridge or freeze up to 2 months. Reheat on a hot sheet pan at 425°F for 8 to 10 minutes, or in the air fryer at 375°F for 5 to 8 minutes until re-crisped. Microwave for convenience, knowing they will be softer.

FAQs
Do I need to peel the sweet potatoes?
Peeling is optional. The skin gets pleasantly chewy and adds nutrients. If the skins look rough, peel them; otherwise scrub well and leave on.
How do I make them extra crispy?
Use a preheated sheet pan, do not overcrowd, dry the potatoes well, and add 1 tbsp cornstarch. Convection bake if available and avoid parchment.
Why did my potatoes turn out soggy?
Soggy results usually come from crowding the pan, starting on a cold pan, or too much moisture. Spread them out and roast hotter.
Are these actually yams?
In the U.S., orange-fleshed sweet potatoes are often labeled yams, but true yams are different. This recipe is for sweet potatoes.
Can I make these on a cast iron skillet?
Yes. Preheat a large cast iron skillet in the oven, then follow the same method. Work in batches to avoid crowding.
