The main ingredient in a frittata is eggs. This versatile dish, often associated with Italian cuisine, typically involves whisking eggs and cooking them slowly in a skillet. Frittatas can incorporate a variety of additional ingredients, including vegetables, cheese, meats, and herbs, allowing for creativity and customization. Unlike an omelet, a frittata is cooked at a lower temperature and often finished in the oven, giving it a denser texture. It's a popular choice for brunch or as a meal for any time of the day, easily served warm or at room temperature.
