Frittata al Forno con Zucchine (Baked Zucchini Frittata)

Frittata is an Italian-style omelette made with beaten eggs and milk, and enriched with various ingredients such as vegetables, cheese, ham, pasta and herbs. For example in the Neapolitan tradition frittata is commonly made with left over pasta (spaghetti, angel-hair, etc.), ham and cheese. The word frittata literally comes from the Italian verb “friggere” to fry. In fact, the egg mixture is usually fried in a frying pan on the stove, but nowadays there is a baked version as well, like my recipe below. Actually, I prefer this method because it makes the frittata lighter on the stomach (no frying) and therefore easier to digest. The addition of zucchini makes this recipe a tasty, dietetic and nutritious dish. Zucchini is rich in water, vitamins (E, C and folic acid), fiber and potassium, while the eggs are highly rich in proteins. With eggs being one of the most readily available and low cost ingredients, frittata has long been a humble dish. Frittata di cipolle (onion frittata) was a typical workers’ lunch. You can serve it warm as a complete meal, at room temperature or even enjoyed cold the next day for a quick lunch or picnic. There is a technical difference between frittata and omelette: the omelette’s ingredients are placed on the omelette while it is cooking, while when making a frittata you must mix the eggs and the other ingredients together before cooking. You may have heard the expression “hai fatto una frittata” … perhaps understandably, that means you made a mess! This expression comes from the fact that frittata is usually made at the last minute with the ingredients available in the fridge, left overs, too!! So the result is not always guaranteed!!!

FRITTATA AL FORNO CON ZUCCHINE (BAKED ZUCCHINI FRITTATA)

Preparation time: 35 minutes     Baking time: 15-20 minutes     Servings: 4

INGREDIENTS

200 g (2 medium) potatoes, boiled and diced
450 g (4 medium) zucchini, thinly sliced
½ medium onion, thinly sliced
4 tablespoons olive oil (Extra Virgin)
50 g (½ cup) grated Parmesan cheese
6 eggs, separate egg yolk from egg white
1 tablespoon parsley, finely chopped
Salt and fresh ground pepper to taste

DIRECTIONS

Preheat oven to 160°C -170°C (325°F -350°F)
1. Wash potatoes under running water. Put potatoes in a pan and cover with cold water. Turn on the heat and bring to boil. Cook for about 6-8 minutes until potatoes are done but not soft. Cool, peel and dice them
2. While potatoes are cooling, wash zucchini under running water and trim ends and slice
3. In a large saucepan over medium-low heat, sauté onions and zucchini in olive oil, stirring frequently for about 10-15 minutes. Stir in parsley and potatoes
4. In a large bowl beat egg yolks, add the vegetable mixture, Parmesan, salt and pepper
5. In a medium bowl beat the egg whites
6. Combine egg whites with vegetable mix and pour it in a 24 cm (10 in) ceramic or glass pie or tart baking dish previously covered with baking paper (see note)
7. Bake for about 15 minutes or until custard is set and golden on top. Don’t open the oven during baking
8. Turn off the oven and let rest for 5 minutes. Remove from the oven and allow to cool on a rack for about 7-8 minutes. Serve warm. You can enjoy the frittata cold too.

Note: Baking paper is very convenient to use. I will tell you a small trick. Cut the paper (bigger than the baking dish), wash under running water and wring the water out. Place the paper in the baking dish. Let the edges go partially up the side of the pan to keep any batter from slipping into the baking dish. This method allows a better adhesion of the paper to the dish wall. Frittata should be stored in an airtight container as water and humidity can alter the texture and taste. If you add greens or vegetables you should first sautee to enhance the flavor. – Paola
