Zucchini and Parmesan Frittata Recipe
Frittata is the Italian cousin of the omelette – thicker, more filling and packed with vegetables. Italians eat it for a quick breakfast, a light lunch, or cut into cubes and served at parties as small bites. This version with zucchini and Parmesan is delicate, fragrant and tastes great both warm and cold.
This frittata combines Italian simplicity with an exceptionally delicate, almost soufflé-like texture thanks to the milk and Parmesan. Zucchini adds a slightly sweet, fresh note, while Parmesan brings deep, savory umami that makes the dish filling yet still light. It’s one of those dishes that taste like breakfast in a small bar somewhere in Tuscany.
Why this version works
- Thoroughly squeezing the zucchini removes excess water, so the center isn’t wet or sunken.
- Cooking over low heat gives evenly set eggs without a burnt bottom.
- Parmesan thickens and seasons the mixture, so there’s no need to add flour or cream.
Chef's tips
It’s a good idea to lightly salt the zucchini and squeeze out the excess water so the frittata doesn’t turn watery and collapse after cooking. Mix the eggs only until combined; don’t beat them for too long, or the texture will be too spongy instead of creamy. Take the frittata out of the oven when the center is still slightly wobbly – it will finish cooking in the residual heat and stay juicy.
How to serve
Serve it with a simple arugula salad drizzled with lemon juice and olive oil, and a slice of crusty sourdough bread. It pairs wonderfully with a milky coffee for a lazy weekend breakfast or with a glass of light, dry white wine for dinner. For a picnic, cut it into wedges and pack in a container – it tastes just as good cold.
Watch out for
- Don’t beat the eggs for too long – a foamy mixture will collapse a lot after cooking and turn spongy.
- Heat that’s too high will quickly burn the bottom while the center is still liquid.
- Don’t cover the pan too early, because the condensed steam will thin the top of the frittata.
Substitutions
- You can replace Parmesan with another hard aged cheese, such as Grana Padano.
- You can swap the parsley for basil or chives to change the herbal character.
- You can replace part of the zucchini with grated, well-squeezed carrot for a sweeter note.
Ingredients
- eggs - 6 pcs
- zucchini medium, about 250–300 g - 1 pcs
- grated Parmesan you can also use grana padano - 40 g
- milk can be replaced with 30% cream - 40 ml
- olive oil - 2 tablespoons
- onion small - 0.5 pcs
- salt to taste
- freshly ground pepper to taste
- fresh parsley chopped; you can use chives - 2 tablespoons
Preparation
- Wash the zucchini, trim the ends and slice into thin half-moons. Sprinkle lightly with salt and set aside for 5–10 minutes until droplets of juice appear. Squeeze thoroughly in your hands or in a towel – the slices should be noticeably drier and flexible, not dripping.
- Peel the onion and finely chop it. In a roughly 24 cm non-stick pan, heat 1 tablespoon of olive oil over medium heat until it starts to shimmer slightly but does not smoke.
- Add the onion and fry for 3–4 minutes, stirring, until it softens and becomes translucent. It should smell sweet and stay pale; if the edges brown quickly, reduce the heat.
- Add the squeezed zucchini and the second tablespoon of olive oil. Fry for 6–8 minutes, stirring from time to time, until the slices soften and their edges brown in spots to a golden color. There should be no watery sauce on the bottom of the pan.
- In a bowl, briefly whisk the eggs with the milk with a fork or whisk, just until combined – the mixture should be uniform but almost without foam. Add the Parmesan, parsley, salt and pepper, and mix until the cheese is evenly distributed.
- Reduce the heat under the pan to low. Spread the zucchini and onion evenly over the bottom, smoothing with a spatula. Pour in the egg mixture, shaking the pan so the eggs fill all the gaps and lightly cover the vegetables.
- Cook over low heat for 8–10 minutes without stirring, until the edges of the frittata are set and matte, and when you move the pan the center only trembles slightly but doesn’t look like runny scrambled eggs.
- If the top is still very runny, cover the pan for 2–3 minutes, checking that the bottom is not getting too dark. If the pan is oven-safe, you can place it under a very hot grill for 2–3 minutes until the top is lightly browned.
- Set the finished frittata aside for 3–5 minutes, until the steam stops escaping intensely and the edges firm up slightly. Gently slide it onto a plate, using a spatula to help, and cut into wedges or cubes. Serve warm or at room temperature.
Storage
Store leftover frittata in an airtight container in the fridge for up to 2–3 days. You can eat it cold, at room temperature, or gently reheat it in a pan or low oven; avoid microwaving too long so it doesn’t become rubbery.
I usually make this frittata on Sunday evening and pack pieces into lunchboxes for Monday – it has already saved more than one hectic morning at work. I once took it to a garden barbecue and it disappeared faster than the sausages.
