Why This Recipe Works

To make this traditional egg dish in individual, brunch-friendly portions, we pour our custard into a muffin tin before baking. Increasing the fat in the mixture by opting for half-and-half instead of milk helps the frittatas release from the pan. A 425-degree oven proved to be the best choice for creating a lightly browned exterior without overcooking the eggs, and a few different options for flavorful filling combinations keep everyone happy.
