Blending the cheese with the tomatoes gives this stunner a lovely orange-ish hue.




  • 1 recipe for Gluten-Free Pie Crust (recipe follows)
  • 1 cup crushed tomato puree
  • 5 ounces grated cheese mixture: I used Pecorino-Romano, Parmigiano-Reggiano and Fontina
  • 3 large eggs, slightly beaten
  • ½ teaspoon kosher salt
  • ¼ teaspoon black pepper
  • ½ teaspoon Sriracha
  • Assorted small heirloom tomatoes
  • Fresh thyme for garnish
  • Fresh chives for garnish (chive blossoms are a pretty touch)


  • 12 Tbsp unsalted butter, frozen
  • 268 grams Gluten-free AP flour mix, cold (freeze for at least 30 minutes)
  • 1 teaspoon psyllium husk (OMIT if your flour mix has xanthan gum already added)
  • ½ teaspoon salt
  • ¼ teaspoon baking powder
  • ½ cup mascarpone cheese, cold
  • 5 Tablespoon ice water



  1. Place chilled dry ingredients into the bowl of a food processor and pulse 3-4 times to blend flours together
  2. Add both butter and mascarpone cheese; pulse until mixture looks like small peas – about 8-10 pulses, give or take
  3. Add water and pulse again until the mixture is more sand-like and it just begins to cling to the side of the work bowl
  4. Dump the mixture onto a lightly floured surface and divide into 2 pieces, pressing/squishing the dough together until it forms a ball
  5. Wrap each piece of dough tightly in plastic wrap and refrigerate overnight; this allows the flours plenty of time to hydrate and makes it easier to handle (you’re only going to use 1 crust for this particular recipe; the other will keep in the refrigerator for 2-3 days or in the freezer, wrapped tightly, for up to 3 months)
  6. About 15 minutes before rolling, remove from refrigerator to let it soften a bit; preheat oven to 400 degrees
  7. Place disk between 2 pieces of parchment and roll – size of dough should be approximately 2-inches larger than the dish/pan you are using
  8. Remove top piece of parchment and carefully, turn the bottom parchment over so that the crust is now able to be placed into tart pan
  9. Gently peel parchment from the crust and nestle the crust into your tart pan; no worries if it tears or is a bit thin near the edges – you’ll use any trimmings to fill in where needed and once the tart is filled and baked, no one is the wiser!
  10. Generously prick the bottom of the tart with a fork; place in the freezer for 20 minutes
  11. Remove tart shell from the freezer and place on a baking sheet; line the tart with a sheet of foil or parchment, fill with pie weights, rice or beans and bake for 20-25 minutes or until just beginning to brown
  12. Carefully, remove the liner and weights, leaving the tart on a rimmed baking sheet; cool


  1. Reduce oven temperature to 300 degrees
  2. Place crushed tomatoes, eggs, cheese, sriracha, salt and black pepper in a blender and blend until frothy
  3. Pour tomato mixture into cooled crust; slice a few of the heirloom tomatoes in half and place cut-side facing up across the tart
  4. Sprinkle with herbs and bake for 45 minutes, rotating halfway through the baking time
  5. The tart is done when a knife inserted in the center comes out clean
  6. Cool completely and serve with more fresh heirloom tomatoes
