Instructions

To make perfect Parmesan Herb Sweet Potato Medallions, attention to detail at each stage of the preparation and cooking process is essential. The following steps are broken down meticulously to ensure consistent results, whether you’re cooking for two or preparing a large batch for entertaining.

Step 1: Gather and Prepare Your Ingredients

Before you begin cooking, take a moment to gather all the ingredients and tools you will need. This not only saves time but ensures you’re not scrambling for something mid-process.

Ingredients Checklist:

• 2–3 medium sweet potatoes (about 1½ to 2 pounds total), scrubbed clean

• 2 tablespoons olive oil (plus extra for brushing)

• ½ teaspoon kosher salt

• ¼ teaspoon freshly ground black pepper

• 1 teaspoon garlic powder

• 1 teaspoon onion powder

• 1 teaspoon dried thyme or 1 tablespoon fresh thyme, chopped

• 1 teaspoon dried rosemary or 1 tablespoon fresh rosemary, finely minced

• ⅓ cup finely grated Parmesan cheese (preferably freshly grated)

• Optional: chopped fresh parsley for garnish

Tools Needed:

• Sharp chef’s knife or mandoline slicer

• Cutting board

• Mixing bowl

• Measuring spoons

• Baking sheet (preferably rimmed)

• Parchment paper or silicone baking mat

• Pastry brush or spoon for drizzling oil

• Oven mitts and cooling rack

Step 2: Preheat the Oven

Preheat your oven to 400°F (200°C). This temperature strikes the right balance between allowing the sweet potatoes to soften and caramelize on the inside while creating a lightly crisp exterior.

Pro Tip: If your oven tends to cook unevenly, consider rotating the baking sheet halfway through baking or using an oven thermometer to ensure accuracy.

Step 3: Slice the Sweet Potatoes into Medallions

Using a sharp knife or a mandoline slicer, cut the sweet potatoes into ¼-inch thick rounds. Try to keep the slices uniform in thickness so they cook evenly. You can leave the skins on for added texture and nutrients, or peel them if you prefer a smoother edge and finish.

Note: A mandoline slicer is highly recommended for consistent thickness, especially if presentation is important or if you’re preparing a large batch.

Step 4: Season the Medallions

In a large bowl, combine the sweet potato slices with olive oil, salt, pepper, garlic powder, onion powder, thyme, and rosemary. Toss gently to ensure each slice is evenly coated.

Make sure the oil lightly coats the entire surface of each medallion. This step is crucial not only for flavor but also to aid in browning and crisping during roasting.

Optional Variation: Add a pinch of smoked paprika or chili flakes here if you prefer a touch of heat or smokiness.

Step 5: Arrange on a Baking Sheet

Line a rimmed baking sheet with parchment paper or a silicone baking mat to prevent sticking and make cleanup easier.

Arrange the seasoned sweet potato slices in a single layer on the sheet. Do not overlap. Overlapping will cause the medallions to steam rather than roast, preventing crisp edges.

Tip: If you’re doubling the recipe or have extra slices, use two baking sheets rather than crowding one.

Step 6: Bake the Medallions – First Round

Place the baking sheet on the center rack of your preheated oven. Bake for 18–20 minutes, or until the bottoms are lightly golden and the edges are starting to crisp.

You may notice the tops puff slightly as they roast. This is normal and part of the caramelization process that enhances flavor and sweetness.

Step 7: Flip and Add Parmesan

After the first baking stage, carefully remove the tray from the oven. Using a thin spatula or tongs, gently flip each medallion.

Sprinkle a small amount of freshly grated Parmesan cheese onto the top of each slice. Press lightly with the back of a spoon to help the cheese adhere.

Tip: Don’t overload the medallions with cheese—just enough to create a flavorful crust. Too much may cause uneven melting or burning.

Step 8: Return to Oven for Final Roasting

Return the tray to the oven and bake for an additional 10–12 minutes, or until:

• The bottoms are deeply golden and slightly crisp,

• The Parmesan has melted and formed a golden crust, and

• The medallions are tender when pierced with a fork.

Keep an eye on the tray during the final few minutes to avoid over-browning the cheese.

Step 9: Rest and Garnish

Once done, remove the baking sheet from the oven and let the medallions rest for 3–5 minutes on the sheet. This allows them to firm up slightly, making them easier to serve.

Sprinkle with fresh chopped parsley or additional thyme if desired, to add a pop of color and fresh aroma.

Step 10: Serve and Enjoy

Transfer the medallions to a serving plate or platter. Serve warm as a side dish or appetizer. These medallions pair wonderfully with:

• Roasted meats such as chicken, turkey, or pork,

• Grilled vegetables or tofu for a vegetarian meal,

• Or as part of a festive holiday spread.
