An elegant frittata recipe for the times when you want a special breakfast or brunch that is also easy to make. It is a lighter and healthier substitute for quiche.
Preheat the oven to 400°F / 200°C / Gas Mark 6 and place the oven rack in the middle of the oven.
Place a pinch of saffron in a small bowl and add 1 TB of just shy of boiling water to the saffron. Set aside and let the saffron steep.
In a medium size bowl, mix the eggs together with a fork until there are no egg whites visible in the mix. Add the Romano cheese and mix again until combined. Set aside.
Thoroughly clean and julienne slice the white and pale green parts of the leek, about an inch and a half in length and about 1/16 of an inch wide. See blog post for a video demonstration.
In a small bowl, whip the ricotta with a pinch of Kosher salt and a few grounds of black pepper until smooth. A fork works nicely for this job. Set aside.
Place an 8-inch (20cm) skillet, preferably a non-stick skillet with an oven-proof handle, on a burner and turn the heat to medium-high. Pour in the olive oil and heat up. Add the sliced leeks and turn down the heat to medium then sauté until soft, but not browned, about 5-7 minutes. Add the prepared spinach, in batches, and cook down until completely wilted and soft, about 5 minutes.
Meanwhile, pour the saffron and water to the eggs, making sure you get every last drop and all saffron threads, and whisk together with a fork.
Pour the egg mixture into the skillet with the spinach and leeks. Tilt the pan to make sure the egg mixture is evenly distributed across the whole skillet. Turn the heat to medium and let the eggs cook undisturbed for a couple of minutes.
Run a thin rubber spatula around the edge of the frittata to loosen the eggs. Pull the eggs toward the center with the spatula creating pockets for uncooked runny eggs to fill up. Repeat this step going around the circumference of the frittata. Continue to gently cook the frittata until there is a thin liquid layer on top of the frittata.
Drop spoonfuls of whipped ricotta cheese around the frittata, about 6-8 spoonfuls. Place the skillet in the oven and cook until it is solid all the way through, about 6 minutes. You may need to place the frittata under the broiler to brown the top. It is not necessary, only if you want browning on the top. If you do, watch the frittata carefully because it should only take a few minutes.
Remove from the oven and run the frittata around the edge of the skillet, then slide the frittata on to a serving plate.
Frittata is best eaten warm the same day it is made.
