Golden Beets and Walnuts Tart

I have come to love beets. I even willingly drank a beet beer once. But the abundance of beets that inevitably comes from our CSA fills me with panic and dread as I try to figure out what I can do with them that my kids will actually eat.

I’ve tried making beet chips, which the younger kid seemed to like, but the older kid rejected because it still tasted too much like well, beets. I then put them in smoothies which the older kid liked but the younger kid rejected probably because it tastes too healthy. And although I think these were a success, I’m not feeding my kids cupcakes each week.

When last week’s share brought us our first bunch of golden beets, I hit the Internet up for some inspiration, searching for beet recipes my kids will eat. Among my search results was this beet, walnut, and chèvre tart. I figured at the very least, they might eat the crust without complaining and we’d call it good.

I adapted this tart in a few ways. It starts with swapping in some whole wheat flour in the crust, which you could say is to make it healthier but really, I thought the nuttiness of the whole wheat would complement the walnuts more. Next, I roasted the beets instead of steaming them, adding some flavor by throwing in some thyme sprigs. More color, as well as a healthful boost and frugal use of the beet tops was added by sautéing the chopped beet greens with the caramelized onions. Lastly, instead of chèvre, I used more kid-friendly Beecher’s Flagship cheese.

The result was gorgeous and glorious! But did my kids like it? Well, the older one picked up a beet suspiciously, asking what it was. My husband and I refused to tell her so she took a bite and gleefully declared it to be a carrot. We probably should have lived up the lie, but told her the truth. After that, her interest in the tart suddenly dropped off.
But the younger one? The one for whom it took 3.5 years before she’d willingly eat a strawberry? She begrudgingly declared it “half good,” but she also did not hesitate to eat more bites, greens and all. My husband gave me a high five on the sly. I’ll take that as highest kid praise when it comes to a hard sell like beets!

Golden Beets and Walnuts Tart

(Adapted from here. )

Tart Shell Ingredients
1 cup all-purpose flour
1/2 cup whole wheat flour
1/2 teaspoon kosher salt
10 tablespoons cold unsalted butter, cut into 1/2 inch cubes
4 to 5 tablespoons ice water

Tart Filling Ingredients
3 small beets, halved
Olive oil
2-3 thyme sprigs
Kosher salt and freshly ground black pepper
1 tablespoon unsalted butter
1 medium onion, thinly sliced
Beet greens, trimmed off of stems and finely chopped
2 tablespoons dry Sherry or whatever dry wine you have on hand
3 large eggs
3/4 cup heavy cream
4 ounces Beecher’s Flagship cheese or a hard, nutty white cheese. Maybe gruyere or even a sharp white cheddar can work
1 cup chopped walnuts (Although I think pinenuts might be a nice swap.)
About 2 tablespoons chopped fresh parsley

Start by making the tart shell. In a food processor, add the flours, salt, and butter. Pulse 8-10 times, holding the button down for 2-3 seconds each pulse, until the butter is the size of small peas. With the processor running, add 4 tablespoons of ice water until the dough just comes together. Remove to a sheet of plastic wrap and clump together into a ball, drizzling more water if the mixture is too dry. Flatten the ball into a disk then wrap tightly in plastic. Chill for at least 30 mins or up to two days.

Preheat your oven to 375. Roll out dough to a 13 inch circle then carefully lay it over a 10 inch tart pan, pressing the dough up and into the sides. Cleanly cut off excess dough by rolling your rolling pin over the top and breaking off the overhanging dough. Place a large sheet of aluminum foil over the crust and fill with pie weights or dried beans. Bake shell on a baking sheet for 20 minutes, then remove from oven. Carefully remove the foil and set shell aside.

To make the filling, start by roasting the beets. Turn your oven to 400 degrees. Place beet halves on a sheet of aluminum foil. Drizzle with olive oil, then season with salt and pepper and top with thyme sprigs. Wrap tightly in foil and bake for 1 hour or until tender. Unwrap beets so they can cool a little.
Heat 1 tablespoon each of unsalted butter and olive oil over medium heat. Add onion and a pinch of salt. Stir to coat in the butter and oil then cover with a lid and reduce heat to medium low. Cook for 7 mins, stirring once halfway through cooking time. Remove lid and continue to cook onions until lightly caramelized, for me, that was about 15 mins more. Add a tablespoon of olive oil and the chopped beet greens, then crank up the heat to medium high. Season with salt and pepper to taste and add the sherry. Cook until greens are wilted, about 3-5 minutes. A lot of liquid will be in the pan. Using tongs, remove the greens and onions to a colander, squeezing out extra liquid as you do. When all of the greens and onions are in the colander, press on them with a wooden spoon to get rid of more excess liquid.
Set the oven to 350 and place the tart pan on a baking sheet.
Place the greens and onions in the bottom of the tart shell. Peel then thinly slice beats crosswise. Place them on top of the greens– you can layer them decoratively, if that floats your boat. In a large liquid measuring cup, whisk the eggs then add the 3/4 cup of cream, and season to taste with salt and pepper. Whisk together until combined then pour over the beets in your tart shell. Break apart the cheese into small crumbles and scatter over your tart.
Bake tart on the baking sheet for 20 minutes then scatter walnuts on top and return to the oven, baking for another 20 minutes or until the filling is firm but still slightly quivers. Remove from oven and let it sit for 10 minutes before scattering parsley on the top and removing the tart from the outside tart shell ring.

Yields 12 slices.
CSA count: 3 (golden beets, parsley, beet greens)
Kid rating (out of two empty plates): 1 empty plate

Notes for the working parent: I made and blind baked the tart shell, roasted the beets, and cooked the greens and onions over the weekend, storing the beets and greens separately in the fridge. I then assembled and baked the tart on a weeknight, giving me lots of downtime while it was baking to shop for workout clothes online, so you know, a relaxed, post-work cooking effort.
