Yes, this. I always use the oven – so much simpler! And I use a glass baking dish because sometimes if the center won’t set (or I’m running out of time) I put it in the microwave for a couple of minutes.
Frittata is awesome. You can serve it for any meal. You can make it vegetarian (or not). You can put almost anything in it: traditional, exotic, mild, spicy, etc. You can serve it hot or cold. Everyone likes it. It’s definitely a cornerstone of my entertaining repertoire.
