It's been a while since I've done a food post, and since I recently revived this recipe and put it back into my rotation, I thought I'd share it with the rest of the class.
Frittatas are, IMO, one of the great unsung food items. They're easy, they're quick, they're portable, and they're massively versatile. You can eat them hot, warm, or cold; you can eat them for breakfast, lunch, or dinner; they're good in summer or winter; you can carry them in a lunchbox or a picnic basket. And you can put just about anything in them -- so you can personalize them to your own preferences, or use them to clear out bits and pieces from your fridge.
Here's my recipe. Except I'm not sure it could be called a "recipe," exactly. It's more of a broad concept.
Stuff that you'd like to have in a frittata. (I told you this was versatile.) Peppers, onions, olives, sausage, asparagus, tomatoes, mushrooms, ham, spinach, peas, corn... pretty much any sort of vegetable, or any sort of meat. I've made frittatas with potatoes (more on that in a moment); and while I haven't yet made this myself, I've heard tell of frittatas being made with day-old cooked pasta.
An ovenproof skillet. A non-stick one is ideal -- if you have something like a good Calphalon pan that can be put in the oven, that's what you want -- but any skillet that can be put in the oven will do. Cast iron is classic, but in my experience it's hard to get a frittata cleanly out of a cast iron pan. Pretty much any size is fine: you can make little frittatas, or big ones.
Oil or butter.
Salt and pepper.
How to make it:
Heat your oven to 375 Fahrenheit.
Take the eggs out of the fridge and let them come to room temperature. (You never, ever, ever want to cook cold eggs if you can possibly help it. Cooking cold eggs makes them rubbery.) For a little pan, like a 7", four eggs will probably be enough; for a 10" pan, I use six; for a bigger pan, eight or ten.
Put oil or butter in your skillet, and heat it up. (Less if you're using a non-stick pan; more if you're not.)
Take the stuff that you want to put in your frittata, and put it in your skillet. If it needs cooking, cook it: it won't cook for very long in the frittata itself. (If it doesn't need cooking, just warm it up a bit.) Sautee your onions or peppers or sausage or whatever, until they're pretty much as cooked as you like. (You can also roast your veggies instead of sauteeing them if you prefer.) IMO, veggies and stuff should be cut up into smallish dice, since the frittata will be hard to eat otherwise. If you're going to do potatoes, slice them very thinly, and sautee them until they're crispy and golden brown. If you're going to use tomatoes, cut them up and drain out the liquid and seeds on paper towels first; otherwise, your frittata will be soupy. Onions are extra-good if they're caramelized.
"How much stuff?" I hear you cry. You want enough stuff that the skillet will be full to about halfway up... but not so much that it's packed solid. When you pour the eggs in, you want a fair amount of the egg to filter down around the veggies and whatnot to the bottom of the pan.
Beat your eggs lightly (they should be thoroughly mixed but not frothy). You don't add milk or anything; just eggs, plus salt and pepper to taste. Turn the heat down to medium low, and pour the eggs into the skillet. (If you aren't using a non-stick pan, make sure there's butter or oil on the sides of the pan as well as the bottom before you put in the eggs. If you are using a non-stick pan, this doesn't hurt, but it isn't as big a deal.)
Cook on the stovetop at medium low until the bottom is set but the top is still runny. The time will vary depending on how big a frittata you're making, but it should only be a few minutes. (About 5 minutes for a 7" pan; a bit more for a bigger one.)
When the bottom is set but the top is still runny, put it in the oven at 375 Fahrenheit, and cook until it's completely set. Again, the time will vary depending on how big a frittata you're making, but it should only be a few minutes. Just keep an eye on it. (About 3-4 minutes for a 7" pan; a bit more for a bigger one. I told you this was quick.)
If you want the top browned, stick it in the broiler for a minute. If you like cheese, grate it on the top at the broiler stage.
Transfer it to a plate. This is the point where you realize why I keep gassing on about non-stick skillets. If you're using cast iron, you'll probably need to slide a butter knife around the edges to loosen it before doing this, and it still may not come out all that pretty. You can also say "Fuck it," and serve it directly out of the pan. Let it rest for a minute, then slice it into wedges like pizza, and serve.
Have fun! And if you make any interesting or unusual or especially tasty versions of this, let me know, as I'm always looking for ideas.
