Savory Tarts

It has been many years since I originally posted my recipe for savory tart (aka slim quiche), and since then I've gotten lots of requests for a recipe for its variants, which I tend to post often on instagram. I bake these quite a bit, as they make nice use of random greens that accumulate in our refrigerator after overly optimistic greenmarket runs. They're a great way to use up radish tops and carrot tops that would otherwise get composted. You can mix in other green odds and ends, such as different combinations of chard, kale, arugula, spinach—and feel good about cutting down on your food waste. Without further ado, the recipe. Please feel free to vary as you see fit—that's what it's all about. 
 

Savory Greens Tart
makes 1 10-inch tart 

Crust

Ingredients: 

• 4 ounces (1 stick) cold, unsalted butter, cut into small pieces 
• 1 3/4 cups flour (all-purpose OR 1 1/4 cup all-purpose and 1/4 cup whole wheat)
• 1/2 tsp salt
• a few tablespoons ice water

Instructions: 

1. Have a 10-inch removable-bottom tart pan ready. Any shallow pie pan works, really, and you can use 9 inch (you'll just have leftover). In a food processor, combine flour and salt, then pulse in butter until it's blended in tiny, coarse chunks (pea sized). Start pulsing in the ice water a few drops at a time, until you get a shaggy mass that's just starting to pull together. Don't add too much water! Once you can press it into a ball, remove from processor and pat into a disk, then wrap in parchment or plastic and refrigerate until firm, about an hour. (*note: you can also make the dough by hand by rubbing the butter into the flour with your palms and fingertips)
2. Preheat oven to 400°. You'll need to blind bake the tart shell. Let the dough come to room temperature for 15 or so minutes, then roll out into a uniform, thin sheet, somewhere between 1/16" and 1/8" thick. Nestle dough over and into the tart pan, pressing gently into corners and against sides. Trim excess with kitchen scissors OR, my preferred trick, roll a rolling pin over the top to lop of the excess. Press against the sides one more time. Prick bottom all over with the tines of a fork, then refrigerate some more (20 minutes or so) until dough firms up a bit. Press together any dough leftovers and use for a smaller tart, or for patching any cracks in the baked tart. 
3. Remove tart mold from fridge and press a sheet of foil on top of dough. Fill with some sort of weight, like dried beans, uncooked rice, or even pennies. Bake in the oven 15-20 minutes, then carefully remove the foil and bake another 5-10 minutes, until golden brown and firm. Cool the shell and save, wrapped, for a day or so—or freeze for future use. 

Greens and feta tart

Ingredients:

•  2 TBS butter or olive oil
• 4 scallions, entire whites and green parts (except for roots), sliced thin
•  Equivalent of 1 large bunch of greens, washed and patted dry. I like to use a mix of radish tops, chard, spinach, kale, arugula, etc. in whatever amounts I have. Keep in mind these cook way down, so what seems like a lot becomes next to nothing!
• optional: 1/4 cup dill and/or parsley
• sea salt & pepper
•  8 eggs
• 1/2 cup cream
• 1/2 cup crumbled feta cheese, heaped high

Instructions: 

1. Preheat oven to 350°. Chop greens into 1/2" slices, including all but the toughest stems (if you're using kale). Chard stems are quite tender once cooked. Put a large skillet on the stove over medium heat. Add olive oil or butter to pan and melt, then add scallions. Saute for a few minutes, then add your greens and sprinkle some salt over them. Saute, stirring occasionally, until they are wilted and have released their liquid. Add dill if you're using, and saute a couple more minutes. Once greens are uniformly wilted, their stems are softened, and liquid is mostly gone, they're ready. Taste and add salt and pepper if they need it. 
2. In a medium bowl, whisk together eggs, cream, and 1/2 tsp. salt for a few minutes, til blended. Set aside. Take out the pre-baked tart shell and put it on a baking sheet. Patch any cracks that may have formed using a bit of leftover dough. Arrange greens in the tart shell, then scatter feta evenly over them. Carefully drizzle the egg mixture over the greens until they are almost, but not quite, covered. You do not want the mixture to go right up to the top, or else it will expand and overflow during cooking. Put tray in the oven and bake for about 20-30 minutes, or when custard no longer jiggles in the center. Check it after 20 minutes, turn, and continue cooking/checking every 5 minutes or so. Some like it just barely set, some prefer it toasty on top. Cool for a few minutes before serving.
