Ingredients
- 2 sweet potatoes, peeled and sliced
- 2 teaspoons minced garlic
- 1 tablespoon olive oil
- 2 tablespoons butter, melted
- 4 tablespoons grated Parmesan cheese
- 1/2 teaspoon garlic salt
- 1/2 teaspoon fresh cracked pepper
- 1/2 teaspoon Italian seasoning
- Fresh thyme
Instructions
- Step 1: Peel the sweet potatoes and slice them thinly. Preheat your oven to 400ºF (200ºC) while preparing the potatoes.
- Step 2: Place the sweet potato slices in a resealable bag. Add the minced garlic, olive oil, melted butter, garlic salt, cracked pepper, grated Parmesan, and Italian seasoning. Seal the bag and shake well to coat all slices evenly.
- Step 3: Lightly butter a baking dish. Arrange the coated sweet potato slices into a spiral pattern inside the dish. Sprinkle fresh thyme leaves on top and add a little extra Parmesan if desired.
- Step 4: Roast in the preheated oven for 30 to 35 minutes, until the edges are crispy and the potatoes are tender. Serve warm, garnished with additional fresh thyme if you like.
Tips & Variations
- For extra crispiness, use a convection oven setting if available, and make sure the potato slices are evenly coated but not overcrowded in the dish.
- Try swapping Parmesan with Pecorino Romano for a sharper flavor.
- Adding a pinch of smoked paprika or chili flakes can give a subtle smoky or spicy kick.
- If you don’t have fresh thyme, dried thyme can be used but add it earlier with the seasonings to release its flavor.
Storage
Store leftover roasted sweet potatoes in an airtight container in the refrigerator for up to 3 days. Reheat gently in the oven or microwave until warmed through. For best texture, reheat in the oven at 350ºF (175ºC) to help retain crisp edges.
