A frittata is an Italian dish made primarily with eggs, similar to an omelet or quiche but typically thicker. It is cooked slowly over low heat and can include a variety of ingredients such as vegetables, meats, and cheeses. The mixture is often finished in the oven to ensure even cooking and a fluffy texture. Frittatas are versatile and can be served hot or cold, making them a popular choice for breakfast, brunch, or even dinner. They are an excellent way to use leftover ingredients, allowing for creativity in the kitchen while providing a nutritious meal option.
