Jump to Recipe

This focaccia sandwich is simple enough for a weekend lunch but impressive enough to serve when friends or family come over. The homemade focaccia can also be made ahead, which makes it a great option for meal-prep sandwiches during the week. Once the bread is baked and cooled, you can slice it into squares and fill each piece with your favorite sandwich toppings.

The best part is the balance of textures and flavors. The focaccia is rich and savory, the pesto adds herby brightness, the prosciutto brings a salty bite, and the mozzarella makes everything creamy. Fresh arugula and tomato keep the sandwich light, while balsamic glaze adds a sweet finish.

Instructions for The Ultimate Focaccia Sandwich

Prepare and fold the focaccia dough.

Mix the garlic rosemary topping.

Create dimples, add the topping, and bake.

Fill the focaccia with sandwich toppings and enjoy.

Proof the yeast:

Mix the warm water with honey, then sprinkle in the yeast. Let it sit for 7 to 10 minutes, or until the top becomes foamy. This shows that the yeast is active and ready to use.

Make the dough:

In a large bowl, combine the flour and salt. Pour in the yeast mixture and stir with a wooden spoon until no dry flour remains. The dough should look sticky and hydrated. Add the olive oil and mix it in with your hands until fully absorbed. Cover the bowl with plastic wrap and let the dough rest at room temperature for 30 minutes.

Develop the gluten:

Use the stretch-and-fold method to build structure in the dough. Wet your hands to prevent sticking, gently lift one side of the dough, stretch it upward, and fold it over itself. Repeat on all four sides. Cover and rest for 30 minutes, then repeat the process two more times.

Shape and rise:

Pour olive oil into a non-stick 9×13-inch baking pan, then transfer the dough into the pan. Stretch it gently toward the edges. If it resists, cover it and let it relax for 15 minutes before stretching again. Cover and let it rise for 45 to 60 minutes, until puffy.

Dimple and bake:

Dip your fingertips in cold water and press them into the dough to create deep dimples. Drizzle the garlic rosemary topping over the surface and sprinkle with kosher salt. Bake at 450˚F for 22 to 25 minutes, or until the focaccia is golden brown. Cool on a wire rack for 10 minutes before slicing.

Assemble the sandwich:

Slice a piece of focaccia in half horizontally. Spread pesto over one side, then layer with prosciutto, arugula, fresh mozzarella, and tomato. Finish with sweet balsamic glaze and a small sprinkle of kosher salt. Place the top piece of focaccia over the filling and serve.

Substitutions for The Ultimate Focaccia Sandwich

Warm Water: Room-temperature water can be used, but it should not be too cold because cooler water may slow the yeast activity.

Honey: Sugar or maple syrup can be used in the same amount to help feed the yeast.

Instant Yeast: Active dry yeast may be used instead, but it should be activated in warm water before mixing it into the flour.

All-Purpose Flour: Bread flour can be used for a slightly chewier texture. Whole wheat flour may also be used, though it can change the texture and flavor of the focaccia.

Salt: Sea salt or kosher salt can be used instead of regular salt. Adjust the amount as needed because different salts vary in saltiness by volume.

Olive Oil: Vegetable oil, canola oil, or melted butter can be used, although olive oil gives focaccia its classic flavor.

Garlic Cloves: Garlic powder or garlic paste can be used in place of fresh garlic. Adjust the amount to taste.

Fresh Rosemary: Dried rosemary can be used, but use less because dried herbs are more concentrated. Fresh thyme or oregano may also work well.

Sandwich Toppings: The toppings are flexible. You can keep the pesto, prosciutto, mozzarella, arugula, tomato, and balsamic glaze combination, or use only the fillings you prefer.

Equipment for The Ultimate Focaccia Sandwich

• Measuring cups
• Measuring spoons
• Cutting board
• Knife
• 2 large bowls
• Small bowl
• 9×13-inch baking dish or pan
• Cooling rack or wire rack
• Basting brush
• Plastic wrap
• Wooden spoon

Storage

Refrigerating: Refrigeration can dry out focaccia quickly, so it is not the best storage method for the bread itself. If the sandwich is already assembled with fresh toppings, store it in the refrigerator and enjoy it as soon as possible.

Freezing: Once the focaccia has cooled to room temperature, wrap it tightly in several layers of plastic wrap and freeze it for up to 2 months. For the freshest flavor, freeze the bread the same day it is made.

Reheating: Thaw the focaccia at room temperature, or use the microwave in 15-second intervals until no longer frozen. To refresh the texture, bake it at 350˚F for about 8 minutes.
