Frittatas are famous for being quick and easy to make and for that reason I find myself baking them quite often whenever I am in need of a simple, weeknight dinner. In the past I have experimented with many different combinations of ingredients, one of my favorites being asparagus and gruyere. Your creativity as a cook is really allowed to shine because there are essentially no rules in frittata-making and the possibilities are pretty much endless. Another great thing is that it’s just as good at room temperature as it is straight out of the oven, so it can be made in advance if necessary.
