Ingredient Checklist


Instructions Checklist
  • Set oven rack on the upper level; preheat to 400 degrees F. Lightly coat a baking sheet with cooking spray or line with parchment paper. Whisk together egg white and 2 tablespoons oil in a small bowl.

  • Lay a sheet of phyllo on the prepared baking sheet, and with a pastry brush, lightly coat the surface with the egg-white mixture. Sprinkle with 1 teaspoon breadcrumbs. Repeat this step, layering 4 more sheets of phyllo on top. Lay the sixth sheet of phyllo on top and brush with the egg-white mixture. To form an edge to the tart, carefully roll over the edges toward the center, using the blade of a knife to help you get started. Spread mustard over the surface of the dough with a rubber spatula and sprinkle with cheese. Arrange tomato slices on top in 5 rows of 8 slices each.

  • Bake until the pastry is golden brown, 15 to 20 minutes. Let cool in the pan for 5 minutes.

  • Combine the remaining 1 tablespoon olive oil, parsley, garlic and thyme in a small bowl. Dab some of the herb mixture onto each tomato slice, using your fingers or a fork. Cut into 12 pieces and serve warm or at room temperature.


Make Ahead Tip: Prepare through Step 3. Wrap and freeze for up to 2 months. Do not thaw before continuing.

I was anxious to try using the egg white/olive oil mixture with the phyllo instead of butter. Unfortunately the end result didn't turn out well. It had a rancid oil taste. My oil egg and breadcrumbs were all fresh newly opened so I dont' think it was that. My phyllo had been in the freezer unopened in it's original package for a while but it wasn't dry or brittle so I don't think it was that either. Ended up throwing it away which was sad because it was the last of my garden tomatoes.:( I think if you tried this using butter it would taste good but it is fairly time consuming to make so I probably won't try this again.
