🥣 How to make Roasted Sweet Potato Medallions

1️⃣ Step One: Preheat oven and slice sweet potatoes into rounds

These baked sweet potato wedges are as simple as it gets, with a prep time of only five minutes and are low maintenance while baking. First, preheat oven to 425 degrees F (230 degrees C).

While the oven is preheating, wash the sweet potatoes and remove any growths or blemishes, but do not peel them. The potato rind helps keep the wedges crispy and held together when baking — and is a good source of fiber and nutrition. Cut potatoes into 1/3 inch (~10 mm) round slices.

2️⃣ Step Two: Season and place on baking sheet

Next, drizzle olive oil onto a large sheet pan and spread the oil until it's even on the baking sheet.

Then, add the potato rounds to pan with one side facing down to coat with oil, then flip all potato medallions to make sure each side is lightly oiled.

Sprinkle the potatoes with salt, pepper, and any additional desired spices. I like to add a bit of paprika and garlic powder, but experiment with your favorite spices to make them your own.

3️⃣ Step Three: Bake until golden brown

Finally, bake in oven for a total of 40-45 minutes, flipping once about halfway through. Both sides should be lightly browned and crispy on the edges.

After I put the potatoes in the oven, I set the timer for 20 minutes, then flip and bake for another 20 minutes. Then I set a timer for five minute intervals if they need a few more minutes after that to get crispy.

❓ Are roasted sweet potatoes healthy?

Potatoes get a bad rap for being high in carbohydrates, but sweet potatoes and yams are actually a nutritionally-dense and sweeter alternative to traditional white potatoes.

One cup of sweet potatoes is only 115 calories, contains 4 grams of fiber, 2 grams of plant-based protein, is an excellent source of vitamin A, and a good source of potassium.

This recipe bakes the sweet potatoes rather than frying them, which reduces unnecessary fats. However, we are adding a bit of healthy plant-based olive oil and just a sprinkle of salt and spices to add flavor, but not overpower the potatoes.

Pair roasted sweet potatoes as a side dish with lean meats or plant-based protein entrees, or as a topping for salads and bowls.

💡 Recipe tips and variation ideas

Baked sweet potato rounds are super simple to make and about as hands-off as it gets, but there are a few tips and tricks to make preparing them even easier.

  • Recommended tools: you'll need a large sheet pan or other baking sheet to cook the potatoes, and a spatula or fork to flip.
  • Choose long and thin potatoes. Bulky or thick potatoes will make for huge slices, so choose a long and thin potato so the round slices are uniform and easy to eat in one or two bites.
  • Oil in the pan or in a bowl? My method of oiling the potato rounds right on the pan reduces the need to toss them in oil in a large mixing bowl (less dishes!), but both ways work. The point is just to oil both sides before baking.
  • Get creative with spices! This recipe is perfect with only salt and pepper, but get creative and try your favorite spices on your sweet potatoes; paprika, garlic powder, cayenne, ginger, cinnamon, sage, and cumin are my favorites
  • Cut potatoes any way you'd like: Don't want to make rounds, or “medallions?” Cut potatoes long and thin into wedges, squares, or whatever shape you'd like. The cooking instructions are still the same.
  • Try toppings! These roasted sweet potato slices are great topped with cheese, vegetables, herbs, and sauces. Experiment and make easy to grab appetizer bites for your next party.
