Description

Parmesan Herb Sweet Potato Medallions combine the natural sweetness of roasted sweet potatoes with the salty, nutty flavor of Parmesan cheese and aromatic Italian herbs.

As the sweet potatoes roast, their edges become golden and lightly crisp while the inside remains soft and tender. The Parmesan cheese forms a delicious savory crust that adds irresistible texture.

Unlike deep-fried potatoes, these medallions are oven-roasted with olive oil, making them a convenient alternative to traditional fried snacks.

Whether served with grilled chicken, roasted vegetables, or your favorite dipping sauce, these Parmesan Herb Sweet Potato Medallions are easy to prepare and full of flavor.

Ingredients

For the Sweet Potato Medallions

• 2 medium sweet potatoes (about 1½ pounds)

• 2 tablespoons olive oil

• ½ cup finely grated Parmesan cheese

• 1 teaspoon garlic powder

• 1 teaspoon Italian seasoning

• ½ teaspoon smoked paprika (optional)

• ¼ teaspoon salt, or to taste

• ¼ teaspoon freshly ground black pepper

For Garnishing

• 1 tablespoon freshly chopped parsley

• 2 tablespoons additional grated Parmesan cheese (optional)

• Fresh thyme leaves (optional)

For the Optional Garlic Yogurt Dip

• ½ cup plain Greek yogurt

• 1 small garlic clove, minced

• 1 teaspoon fresh lemon juice

• ¼ teaspoon dried dill

• Salt and black pepper, to taste

Step-by-Step Instructions

Step 1: Preheat the Oven

Preheat your oven to 425°F (220°C).

Line a large baking sheet with parchment paper or lightly grease it with olive oil.

A hot oven helps the sweet potatoes develop beautifully golden edges while keeping the centers tender.

Step 2: Prepare the Sweet Potatoes

Wash the sweet potatoes thoroughly under cold running water.

Scrub the skins gently to remove any dirt.

You can leave the skins on for extra fiber and texture or peel them if preferred.

Using a sharp knife, slice the sweet potatoes into evenly sized rounds approximately ¼–⅓ inch thick.

Try to keep all the slices similar in thickness so they cook evenly.

Step 3: Season the Sweet Potatoes

Place the sweet potato rounds in a large mixing bowl.

Drizzle with olive oil and toss gently until each slice is evenly coated.

Add garlic powder, Italian seasoning, smoked paprika, salt, and black pepper.

Mix thoroughly to distribute the seasonings across all the medallions.

Step 4: Add the Parmesan Cheese

Sprinkle the finely grated Parmesan cheese over the seasoned sweet potato slices.

Toss gently until the Parmesan coats both sides of the rounds.

For an extra crispy cheese crust, sprinkle a little additional Parmesan directly onto the prepared baking sheet beneath each sweet potato slice.

Step 5: Arrange on the Baking Sheet

Place the sweet potato medallions on the prepared baking sheet in a single layer.

Leave a little space between each round.

Avoid overlapping the slices because overcrowding traps steam and prevents the edges from becoming crisp.

If necessary, use two baking sheets.

Step 6: Roast Until Golden

Transfer the baking sheet to the preheated oven.

Roast for approximately 15 minutes.

Carefully flip each sweet potato medallion using a spatula.

Continue roasting for another 10–15 minutes until the potatoes are fork-tender and the edges are golden brown.

Keep an eye on the Parmesan during the final few minutes to prevent burning.

Step 7: Prepare the Optional Garlic Yogurt Dip

While the sweet potatoes are roasting, prepare the dipping sauce.

In a small bowl, combine Greek yogurt, minced garlic, lemon juice, dried dill, salt, and black pepper.

Stir until smooth and creamy.

Refrigerate until ready to serve.

Step 8: Garnish and Serve

Remove the roasted medallions from the oven.

Allow them to rest on the baking sheet for 2–3 minutes so the Parmesan crust can firm up.

Transfer to a serving platter and sprinkle with freshly chopped parsley, additional Parmesan, and optional fresh thyme.

Serve warm with the garlic yogurt dip or your favorite dipping sauce.

Tips and Notes

Slice evenly: Uniformly sliced sweet potatoes roast more consistently and prevent some pieces from burning while others remain undercooked.

Use finely grated Parmesan: Finely grated cheese adheres better to the potato slices and creates a more even, crispy coating.

Avoid overcrowding: Give each medallion enough space to roast properly.

Roast at high heat: A temperature of 425°F helps develop golden edges and caramelized flavor.

Don’t use too much oil: Excess oil can make the potatoes greasy and prevent the cheese from crisping properly.

Serve immediately: Parmesan Herb Sweet Potato Medallions taste best when freshly roasted and slightly crispy.

Use a metal baking sheet: A sturdy metal pan encourages better browning than a glass baking dish.

Delicious Variations

Spicy Parmesan Sweet Potato Medallions

Add ½ teaspoon chili powder or ¼ teaspoon cayenne pepper to the seasoning mixture for a delicious spicy kick.

Garlic Butter Sweet Potato Medallions

Replace 1 tablespoon of olive oil with melted butter for a richer garlic butter flavor.

Rosemary Parmesan Medallions

Replace Italian seasoning with 1 teaspoon finely chopped fresh rosemary.

This variation is especially delicious with roasted chicken or beef.

Extra Cheesy Sweet Potato Medallions

Sprinkle an additional ¼ cup Parmesan cheese over the potatoes during the final 5 minutes of roasting.

Air Fryer Sweet Potato Medallions

Preheat the air fryer to 380°F (193°C).

Arrange the seasoned sweet potato rounds in a single layer and air fry for approximately 12–16 minutes, flipping halfway through.

Cooking times may vary depending on slice thickness and the air fryer model. Check frequently to avoid burning the cheese.

Serving Suggestions

Parmesan Herb Sweet Potato Medallions are incredibly versatile and can be served with a variety of dishes.

They pair beautifully with grilled chicken, baked fish, roasted beef, and fresh garden salads.

For a vegetarian meal, serve them alongside sautéed mushrooms, roasted asparagus, or a colorful Mediterranean vegetable dish.

These crispy sweet potato rounds also make excellent appetizers for parties and family gatherings.

Arrange them on a large platter with garlic yogurt dip, ranch dressing, or a spicy mayonnaise sauce.

For a holiday dinner, serve them as an alternative to traditional roasted potatoes.
