Ingredients You Need

Here’s the lineup to bring your Parmesan Herb Sweet Potato Medallions to life—each ingredient plays a bold role in creating crispy baked sweet potato medallions that pop with flavor.
- 2 large sweet potatoes, peeled and sliced into ¼-inch thick rounds for perfect medallions
- 3 tablespoons olive oil (or avocado oil as a swap if you prefer a neutral flavor)
- ½ cup freshly grated Parmesan cheese, the key for that heavenly Parmesan cheese topping
- 2 teaspoons fresh rosemary, finely chopped (a must for my favorite garlic and rosemary sweet potatoes vibe)

Let’s Make Some!
Get ready, fellow flavor adventurers—making these Parmesan Herb Sweet Potato Medallions is pure delicious magic! Here’s our step-by-step guide so you can bring this crispy baked sweet potato medallions recipe from pantry to plate in no time.
- Preheat your oven to 425°F. This high heat is what gives those roasted sweet potato slices their irresistible crispy edges while keeping the centers tender and soft.
- Dry your sweet potato medallions thoroughly after slicing. Moisture is the enemy of crispiness, so pat each slice with paper towels.
- In a large bowl, toss the sweet potato slices in olive oil, minced garlic, chopped rosemary, thyme, salt, and pepper. This herb seasoned sweet potatoes mix is where the magic starts happening! Everything coats those medallions evenly, setting the flavor stage.
- Arrange the medallions in a single layer on a parchment-lined baking sheet—no overcrowding or stacking! This helps get every slice perfectly crisp.
- Sprinkle the freshly grated Parmesan cheese over each sweet potato slice. This Parmesan cheese topping will melt and form a crispy, golden crust thanks to our oven heat.
- Bake for 20-25 minutes, flipping halfway through. In my kitchen, this Parmesan Herb Sweet Potato Medallions usually takes just under 30 minutes from start to finish. Keep an eye on the Parmesan cheese—once it crisps up and turns golden, you know you’re there!
- Pull them out of the oven and let cool briefly. Your Parmesan Herb Sweet Potato Medallions should smell absolutely incredible right now—garlic, rosemary, Parmesan, all mingling together.
Not nervous if some medallions look more golden than others—that’s part of their crispy charm! For faster prep, prepping the roasted sweet potato slices earlier in the day and baking when ready is a lifesaver.
