The Main Players

Egg whites: You'll need 6 large ones (that's about 180g/6oz ). Room temperature is key. Honestly? Room temperature makes all the difference. Trust me. I once used cold egg whites, never again.
Milk: 2 tablespoons. Any kind works! Whole, skim, almond, oat... you do you.
Olive oil: Just 1 tablespoon. Extra virgin for extra flavour if you're feeling boujee.
Salt: 1/2 teaspoon This enhances all the flavors.
Black pepper: 1/4 teaspoon Freshly ground is always better, but pre-ground is fine too.
Red pepper flakes: A pinch. Optional, but adds a nice kick.

Filling Fantasticness

Olive Oil: 1 tablespoon
Spinach: 1 cup (75g/2.6 oz) Roughly chopped. Fresh is best, but frozen works in a pinch. Just squeeze out the excess water after thawing, nobody wants a soggy Cheesy Egg Frittata .
Red onion: 1/4 cup (40g/1.4 oz) Finely diced. Adds a lovely sweetness.
Feta: 1/4 cup (30g/1oz) Crumbled. Salty and delicious! Gotta love a Spinach Feta Frittata Recipe . Honestly it’s a game changer.

Seasoning Notes: A Symphony of Flavours

Seasoning is where the magic happens, right? For this Vegetarian Frittata Recipe , simple is often best. Salt, pepper, and a touch of red pepper flakes are your essentials.

Feta is a flavour enhancer. If you want something special, nutmeg is a great touch. If you don't have Feta, try goats cheese or a very sharp cheddar.

No fresh Parsley? Use dried parsley, but remember the ratio: 1 tsp dried equals 1 tbsp fresh.
