Then, add another layer of the Sweet Potatoes on top of the first layer and repeat with the Olive Oil, Herbs, salt and Pepper until you have used all your sliced sweet potatoes.
BAKE!
Bake for 20 minutes at 400F/200C (Every oven heats differently, monitor your Sweet Potatoes from 18min). Then, carefully take your Flexiflat™ out onto your stove. Sprinkle the Grated Parmesan and return to the oven for an additional 2 minutes.
Once your Rosemary Roasted Sweet Potatoes are out of the oven, let them cool down for about 5 minutes, then transfert them onto your service platter. Enjoy & Bon Appétit.
