Frittatas are Italy’s answer to the French omelette and the Spanish tortilla. Fillings are limited only by what’s in season and the cook’s imagination – common inclusions in the frittata are asparagus, onions, or mushrooms, but just about anything can be used as a filling – even pasta! For this recipe, we’ll use zucchini, as they are in season almost everywhere in August. The filler should be lightly and simply cooked – a quick saute or blanch before being incorporated into the egg mixture.
There are three critical elements to a good frittata: a non-stick pan, low heat, and a (non-stick safe) spatula. The pan lets you cook the frittata without much oil, the low heat cooks the eggs through without burning, and the spatula is used to lift the edge as it cooks to allow the uncooked egg to flow underneath.
