This keto tomato tart recipe is loaded with flavor from the creamy ricotta, sweet tomatoes, herby garlic oil, and salty crispy prosciutto! Perfect for entertaining or anytime!



For the crust:

  • 1/2 cup butter, softened
  • 1/2 teaspoon coarse kosher salt
  • 2 tablespoons coconut flour
  • 2 cups almond flour
  • 1/4 teaspoon xanthan gum
  • 2 tablespoons beaten egg

For the ricotta:

  • 1/2 cup whole milk ricotta
  • 1 teaspoon dried parsley
  • 1/2 teaspoon coarse kosher salt
  • 1/8 teaspoon black pepper
  • 1/4 cup grated Parmesan cheese

For the garlic oil:

  • 2 tablespoons olive oil
  • 1/2 teaspoons fresh garlic, minced
  • 1/2 teaspoons fresh oregano, minced
  • 1/4 teaspoon coarse kosher salt

For the topping:

  • 1 1/2 cups cherry tomatoes, halved (or 2 medium sized tomatoes sliced into 1/4 inch slices.)
  • 2 slices prosciutto, cut into thin strips


For the crust:

  1. Mash the butter and salt together with a fork in a medium bowl. Add the coconut flour, almond flour, beaten egg, and xanthan gum and work with the fork until fully combined.
  2. Form the dough into a tight ball, wrap with plastic wrap and chill for at least 1/2 hour.
  3. Once chilled, place the ball of dough onto a piece of parchment paper. Cover with another piece of parchment (or wax paper) and roll into a 16 inch disk. Peel off the top layer of parchment paper carefully and place the disk and bottom parchment layer onto a cookie sheet.

For the ricotta layer:

  1. Combine the ricotta cheese, parsley, salt, pepper, and Parmesan cheese in a small bowl and mix thoroughly.

For the garlic oil:

  1. Combine the olive oil, garlic, oregano, and salt in a small bowl.

To assemble the tart:

  1. Preheat the oven to 375 degrees (F)
  2. Spread the ricotta layer over the raw crust, leaving a 2 inch border of crust with no ricotta.
  3. Top the ricotta layer with the cherry tomato halves, and then the prosciutto.
  4. Fold the 2 inches of the edge of the crust up over the sides of the filling.
  5. Drizzle the garlic oil over the top of the tart.
  6. Bake the tart in a 375 degree (F) oven for 35 minutes or until golden brown.
  7. Serve warm or chilled.
