The first tip in frittata making is choosing the right pan. Our choice of pan is a ceramic, non-stick oven-safe 10-inch skillet because it makes life so much easier knowing the frittata will slide right out when it is finished. We also finish frittatas in the oven for a nice browned top, so oven-safe, meaning no plastic parts is crucial. Also, be sure you use a non-toxic skillet. No PFOAs etc.
