Are McDonald's eggs microwaved or grilled before serving?

Well, it depends on which egg you’re referring to. Our freshly cracked and scrambled eggs are cooked on the grill with liquid real butter. We also use the grill to heat our folded egg, which is previously cooked in our suppliers’ kitchens before arriving at our restaurants. As for the eggs used in our Sausage Burrito, we cook these in our suppliers’ kitchens then microwave in our restaurants prior to serving.
