In a large bowl, add the room temperature water, flour, instant yeast, and sea salt, ensuring that the yeast and salt are placed on opposite sides of the bowl before combining. Mix by hand, squeezing the dough between your fingers until a sticky, homogeneous mass is formed. Cover the bowl with plastic wrap and let the dough rest for 20 minutes.

After the initial resting period, perform a set of stretches and folds to strengthen the dough, then repeat after 20 minutes and again after another 20 minutes. Shape the dough into a ball and rub it with two tablespoons of olive oil to keep it moist. Cover with plastic wrap and let the dough rest for an additional 20 minutes. I like to take my time with the stretches and folds, making sure the dough feels elastic and smooth.

Divide the rested dough into three equal pieces. Grease three 7.5" x 5" foil pans with two tablespoons of softened butter. Transfer each piece of dough to a pan and stretch it to fill the bottom of each pan. Cover with plastic and refrigerate the pans overnight or for up to 24 hours, allowing the dough to ferment slowly for maximum flavor.

Remove the pans from the refrigerator two hours before you plan to bake. Let the dough proof at room temperature, covered with plastic wrap, so it can become light and airy.

Generously drizzle olive oil over the top of each dough. Using your fingers, make deep dimples all over the surface to create those iconic focaccia pockets. Evenly distribute the thinly sliced or minced garlic, black pepper, and mixed fresh herbs over the dough. Finish with another light drizzle of olive oil for extra flavor and a golden crust. For a fresher taste, I like to use a mix of fresh herbs rather than just one kind.

Bake in an air fryer set to 400°F (or the highest temperature setting) for about 12 minutes, checking early as air fryer times may vary. Continue baking until the focaccia is golden and cooked through. When done, carefully transfer the focaccia to a large cutting board, slice, and serve while hot. This is when it tastes the best—enjoy with friends or family for maximum enjoyment!
