Cook the leeks in butter:

In an 8 to 9-inch oven-proof stick-free pan (like hard anodized aluminum with stainless handle) or well seasoned cast-iron pan,

melt butter on medium heat. Add the sliced leeks and gently cook until softened, about 10 minutes.

1.

Add artichoke hearts, tarragon, salt:

Once the leeks are cooked through and softened, add the artichoke hearts, tarragon, and salt. Cook until the artichoke hearts are

warmed through, then remove from pan to a bowl and set aside.

2.

Make the egg batter:

In a medium bowl, whisk together the eggs and the cottage cheese.

In a small bowl, whisk together the flour, Parmesan, and baking powder.

Add the flour mixture to the egg mixture and whisk.

Stir the artichokes and leeks into the egg mixture. Note that the color of the mixture may change, don't worry if this happens, it

will go back to normal when cooked.

3.

Pour egg mixture into pan and gently cook:

Wipe out the pan with a paper towel. Then melt another tablespoon of butter into the pan on medium heat, and swirl along the

bottom and sides to coat well. Pour the egg mixture into the pan, swirling to make sure the artichokes and leeks are evenly

distributed.

Lower the heat. Cover the pan, slowly cook on the stove top for 12 to 15 minutes, until all but the center has set. You'll need to

check every few minutes.

The heat should be high enough to set the mixture, but low enough so that the edges don't brown. This frittata benefits from slow,

gentle cooking.

4.

Finish in the broiler:

Place rack in upper third of oven. Preheat the broiler. When the frittata is mostly set, except for the center which is still wiggly,

place the pan in the oven. Broil for 3 to 4 minutes until the top is lightly browned and the center has set.

Serve:

Remove pan from oven. (Be careful about the hot handle! Use a pot holder. I like to run an ice cube over the handle to to be

extra safe.) Use a blunt knife or a metal spatula to loosen the edges of the frittata from the pan. Gently insert the spatula under

the frittata to loosen it from the bottom of the pan. Then gently slide the frittata onto a serving plate.

Garnish with chives or parsley to serve.
