Savory heirloom tomatoes with rich cheese...a real summer treat!



  • 1 cup all-purpose flour

  • 1⁄2 cup cornmeal

  • 1⁄2 teaspoon salt

  • 1 teaspoon black pepper

  • 1⁄2 cup Gruyère cheese, grated

  • 12 tablespoons unsalted butter, cold, cut into cubes

  • 1⁄4 cup ice water

  • 1 egg beaten


  • 1 - 2 tablespoons unsalted butter (or olive oil)

  • 1 onion, thinly sliced

  • salt & pepper

  • 5 - 7 sprigs fresh thyme

  • 4 - 6 ounces blue cheese, crumbled

  • 4 ounces sharp cheddar cheese, grated

  • 1⁄4 cup Gruyere cheese, grated

  • 1⁄4 cup fresh basil leaves

  • 2 - 3 small to medium heirloom tomatoes, sliced

  • 5 cherry or grape tomatoes, halved

  • olive oil for drizzle

  • honey for drizzle



Step 1

In a food processor, combine flour, cornmeal, salt, black pepper and Gruyère cheese. Pulse several times to mix. Add cold cubed butter and pulse until the butter is in small pieces, about the size of tiny beads. Add 1⁄4 cup of ice water, pulse until dough takes form. Add an extra 1-2 tablespoons of ice water if needed.

Step 2

Place dough on floured surface and knead a few times into a flat disk. Wrap dough in plastic and refrigerate for a minimum of 30 minutes.


Step 3

Melt butter, or use or olive oil, in a skillet over medium-high heat.

Step 4

Add sliced onions, 1/4 teaspoon of salt, 1/4 teaspoon of black pepper. Cook until the onions soften, about 5 minutes. Continue cooking and scrape the browned bits off the bottom of the pan until the onions are golden brown. Stir in the fresh thyme during the last minute of cooking, set pan aside.

Step 5

Remove dough from fridge, flour your work surface and roll out dough to 1/8-inch thickness. Transfer to a parchment lined baking sheet or pizza stone.

Step 6

Crumble blue cheese, sharp cheddar and Gruyère cheese over dough. Add caramelized onions evenly over the cheese layer. Add basil leaves over onion layer. Add tomatoes as the final layer. Sprinkle with salt and pepper, drizzle with olive oil. Then, drizzle lightly with honey.

Add tomatoes as the final layer.

Step 7

Fold over the edge of the dough to form a nice edge for the galette to hold in the toppings. Beat the egg and brush the crust. Place the galette in the refrigerator for a minimum of 15 minutes.

Step 8

Preheat oven to 375° F. Bake the galette for 50 minutes, depending on your oven, until the crust is golden brown. The tomatoes should look roasted. Let cool for 5 minutes, cut into slices and serve.


May be served with fresh tomatoes and pepper flakes with more honey drizzle. You may also try a little balsamic vinegar.
