Ingredients

2 Tbsp all purpose flour (omit for gluten-free version)
1/2 teaspoon baking powder
2 Tbsp butter
8 ounces (1 cup) small curd cottage cheese (can use ricotta if you prefer)
5 eggs
Fresh chopped chives or parsley for garnish
1/2 teaspoon dried tarragon (can sub 2 teaspoons of chopped fresh tarragon, or dried herbes de Provence or dried thyme)
4 ounces frozen artichoke hearts, thawed, sliced into 1/2-inch slices
1/4 teaspoon Kosher salt
2 cups sliced, cleaned leeks, white and light green parts only (sliced in half lengthwise, then sliced crosswise, about 1/4-inch thick slices)
1 cup grated Parmesan cheese

Cooking Instructions

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.
INGREDIENTS:
EQUIPMENT:

Add the sliced leeks and gently cook until softened, about 10 minutes. 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 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 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.

EQUIPMENT:

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

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.5

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.
