Peel and cube a couple pounds of sweet potatoes, toss them in olive oil, salt, pepper, garlic powder, and fresh rosemary, then spread them out on a baking sheet.

Give the potatoes room to breathe! If they’re too close together, they’ll steam instead of roast. Use two pans if you need to.

Roast them for about 25–30 minutes, flipping halfway so they get nice and golden.

Once they’re tender and crispy, sprinkle on some fresh Parmesan and pop them back in the oven for 5 more minutes to melt.

Yes! You can chop the potatoes a day ahead and store them in cold water in the fridge. Just drain and dry them really well before roasting.

Can I use other herbs with rosemary?

Are sweet potatoes supposed to be soft inside?
