There’s something about those tender centers paired with the cheesy, garlicky crust that just feels like a warm hug on a plate.

You know, I initially struggled with getting the sweet potato rounds crispy enough without them turning mushy.

Ingredients for Parmesan Herb Sweet Potato Medallions neatly arranged on a kitchen counter

Ingredients:

  • 3 large sweet potatoes, peeled and sliced into ½-inch thick medallions
  • 3 tablespoons olive oil (I always use extra virgin for that rich flavor in my Parmesan Herb Sweet Potato Medallions)
  • ½ cup freshly grated Parmesan cheese (this Parmesan cheese sweet potato recipe really hinges on fresh Parmesan – no pre-grated bags!)
  • 2 teaspoons garlic powder (or 3 cloves of minced garlic if you’re loving those garlic herb sweet potato rounds)
  • 1 teaspoon dried rosemary (or use fresh if you can find it; it adds a lovely piney note)
  • 1 teaspoon dried thyme
  • 1 teaspoon salt
  • ½ teaspoon freshly ground black pepper
  • Fresh parsley, chopped (for garnish, optional but highly recommended)

When you’re shopping for ingredients to make Parmesan Herb Sweet Potato Medallions, sweet potatoes can usually be found year-round in the produce section, but I’ve noticed that the sweeter ones come by late fall. A little kitchen wisdom: it’s worth choosing firm, unblemished sweet potatoes for better roasting results. Here’s a Parmesan Herb Sweet Potato Medallions trick I learned from my mom – dry your sweet potato slices really well after peeling to help them crisp up better in the oven.

If you’re short on time, you can use pre-peeled sweet potatoes from the store, but slicing them yourself ensures the medallions are all the same thickness, which is key for even cooking and crispy results. Planning to make a batch for the week? You can store any leftover raw sweet potato medallions in an airtight container in the fridge for up to 2 days, ready to bake when time allows.

How to Make Parmesan Herb Sweet Potato Medallions – Step-by-Step:

  1. Preheat your oven to 425°F (220°C). Lining your baking sheet with parchment paper or a silicone baking mat makes cleanup easier and helps with those crispy sweet potato medallions.
  2. Slice the sweet potatoes into ½-inch thick rounds — think of these as the perfect size for Parmesan Herb Sweet Potato Medallions, crispy yet tender. A good trick to get even slices: use a mandoline if you have one, but a sharp chef’s knife works too!
  3. Place the sliced medallions in a large bowl, and drizzle with olive oil. Toss gently but thoroughly so each piece is coated – this little oil hug is essential for that roasted crispy texture we’re after.
  4. Sprinkle garlic powder, rosemary, thyme, salt, and pepper over the medallions. For a garlicky punch, sometimes I swap garlic powder for fresh minced garlic; it turns the medallions into irresistible garlic herb sweet potato rounds.
  5. Add the freshly grated Parmesan cheese and toss again. This step is pure magic — you’ll see the cheese stick to the medallions, preparing those wonderful crispy edges. In my kitchen, Parmesan Herb Sweet Potato Medallions usually take about 25-30 minutes to roast and come out beautifully crisp on the outside while soft inside.
  6. Arrange the medallions in a single layer on your prepared baking sheet — don’t overcrowd, so they crisp rather than steam. This is where patience pays off!
  7. Roast for 25-30 minutes, flipping halfway through. You’ll want to see those golden edges and a rich aroma in your kitchen — your Parmesan Herb Sweet Potato Medallions should smell like garlic and herbs basking in buttery Parmesan heaven. If you want to speed things along and get an airier crisp, try the air fryer method from this great guide on Parmesan Herb Air Fryer Sweet Potatoes.
  8. When they’re done, remove from the oven and let cool for a few minutes before serving — this helps them firm up and become those crave-worthy crispy sweet potato medallions we all love.

Don’t worry if your first batch isn’t perfect; I’ve made my fair share of floppy or burnt medallions before finding that perfect timing and temperature. While these Parmesan Herb Sweet Potato Medallions roast away, I usually prep a quick salad or get the table ready. These moments make the whole cooking process feel cozy, not rushed.

FAQs:

Q: Can I make Parmesan Herb Sweet Potato Medallions ahead of time?
A: Absolutely! You can slice and season your sweet potatoes the day before, store them in an airtight container in the fridge, and then roast them fresh when ready. I’ve also frozen cooked medallions and reheated them in the oven with good results. Just be sure to avoid sogginess by crisping them back in the skillet if you’ve frozen leftovers.

Q: What if my sweet potato medallions aren’t getting crispy?
A: Oh, I’ve been there! The main culprits are usually too much moisture or overcrowding on the pan. Make sure you dry your slices well before oil and cheese coating, and space them out on the baking sheet. You can also try flipping halfway through and finishing with a quick broil to get crispy edges. For more tips on crispy sweet potato medallions, the post on Cheesy Garlic and Herb Smashed Sweet Potatoes | The Kitchn has some great pointers.

Q: Can I use other types of cheese besides Parmesan?
A: For my Parmesan Herb Sweet Potato Medallions, Parmesan’s nutty flavor is key, but I’ve experimented with Pecorino Romano or a little Asiago. Just keep in mind they melt differently; the medallions might be less crispy but still delicious!

Q: Is baking the only way to cook these sweet potato medallions?
A: Not at all! You can pan-fry them in a skillet for a golden crust or air-fry for a faster crunch—here’s a neat resource on Parmesan Herb Air Fryer Sweet Potatoes. The oven method is hands-off, but sometimes I do a combination.

Q: My kids don’t love the herbs; can I omit them?
A: Sure thing! Sometimes I just go with garlic and Parmesan only, and even my youngest gobbles them up. Herbs add extra flavor but aren’t make-or-break.

Q: How do I store leftover Parmesan Herb Sweet Potato Medallions?
A: Store them in an airtight container in the fridge for up to 3 days. Reheat in the oven at 350°F on a baking sheet until warmed through and crispy again.

Q: Can I use sweet potato wedges instead of medallions?
A: Yes! The cooking time will be a bit longer for thicker wedges, but you get the same flavor profile. This recipe for baked garlic Parmesan potato wedges uses a similar seasoning that works well.
