Two things set this vegan and gluten-free tart apart from your run-of-the-mill vegetable tart: a chickpea flour crust and a layer of lemon cashew cream. The tart is great warm or at room temperature, so you can make it ahead for a brunch or casual supper.

Preparation

  1. Puree all of the cashew cream ingredients in a food processor until very smooth and thick. This will take several minutes, and may require scraping down the sides of the processor. If the mixture seems to dry to become creamy, add one or two teaspoons of water as needed.
  2. For the vegetables, heat the olive oil in a large deep skillet or Dutch oven. Cook the onions and salt over low heat for 45 minutes to one hour, until golden and soft. Add the greens and cook until tender, about 4-8 minutes (kale will take longer than chard). Drain off any excess liquid. (Alternatively, just mix in a cup or so of previously-cooked greens.) Stir in the balsamic vinegar.
  3. To make the dough, mix the chickpea flour, salt and thyme. Drizzle the olive oil over the flour mixture and work together with your hands until crumbly. Add the water and mix very briefly, just until dough comes together (add an additional teaspoon of water if the dough seems too dry.)
  4. Flatten the dough into a disk on a floured work surface (I used all purpose flour for the work surface, but you can use a gluten-free flour.) Roll it out with a rolling pin to about 1 inch larger than the diameter of your tart pan.
  5. Loosen the pastry by slipping a pastry lifter or metal spatula underneath. Fold in half and carefully transfer to the tart pan, pressing it into the bottom and sides. Trim off any excess.
  6. Heat the oven to 400 degrees. Cover the crust lightly with foil (don’t press), add some dried beans or pie weights and bake for 10 minutes. Let cool slightly.
  7. Top the partially-baked crust with the cashew cream, then the onion and greens mixture. Return to the oven and bake for 20 minutes longer. Serve warm or at room temperature.
