Whisk half of the water (1 cup; 240ml), 2 teaspoons sugar, and 2 teaspoons yeast together in the bowl of your stand mixer fitted with a dough hook or paddle attachment. Cover and allow to rest for 5 minutes.

Add the remaining water, olive oil, salt, and 1 cup (130g) flour. Beat on low speed for 20 seconds, then add 3 and 1/2 cups (440g) more flour. Beat on low speed for 2 minutes. If the dough is still sticking to the sides of the bowl, add the last 1/2 cup (60g) of flour.

Keep the dough in the mixer and beat for an additional 5 full minutes, or knead by hand on a lightly floured surface for 5 full minutes. (If you’re new to bread-baking, my How to Knead Dough video tutorial can help here.) If the dough becomes too sticky during the kneading process, sprinkle 1 teaspoon of flour at a time on the dough or on the work surface/in the bowl to make a soft, slightly tacky dough. Do not add more flour than you need because you do not want a dry dough. After kneading, the dough should still feel a little soft. Poke it with your finger—if it slowly bounces back, your dough is ready to rise. You can also do a “windowpane test” to see if your dough has been kneaded long enough: tear off a small (roughly golfball-size) piece of dough and gently stretch it out until it’s thin enough for light to pass through it. Hold it up to a window or light. Does light pass through the stretched dough without the dough tearing first? If so, your dough has been kneaded long enough and is ready to rise. If not, keep kneading until it passes the windowpane test.

Lightly grease a large bowl with a teaspoon of oil or some nonstick spray—just use the same bowl you used for the dough. Place the dough in the bowl, turning it to coat all sides in the oil. Cover the bowl with aluminum foil, plastic wrap, or a clean kitchen towel. Allow the dough to rise at room temperature for 2–3 hours or until double in size. (Tip: For the warm environment on a particularly cold day, heat your oven to 150°F (66°C). Turn the oven off, place the dough inside, and keep the door slightly ajar. This will be a warm environment for your dough to rise. After about 30 minutes, close the oven door to trap the air inside with the rising dough. When it’s doubled in size, remove from the oven.)

Generously grease a 12×17-inch baking pan (with at least 1-inch-tall sides) with 2 Tablespoons of olive oil. This is the base layer of the bread, so be generous with the oil. A pastry brush is helpful to spread it.

When the dough is ready, punch it down to release any air bubbles. Place on the oiled baking pan, then stretch and flatten the dough to fit the pan. Don’t tear the dough. If it’s shrinking (mine always does), cover it with a clean towel and let it rest for 5–10 minutes before continuing. This lets the gluten settle and it’s much easier to shape after that.

Cover the dough tightly and let it rest in the refrigerator for at least 1 hour and up to 24 hours. The longer it rests, the better the flavor. I recommend at least 12 hours.

Remove the dough from the refrigerator and let it sit at room temperature as you preheat the oven and prepare the toppings. Keep it covered. It may rise a little during this time, but not much.

Preheat oven to 450°F (232°C). Allow it to heat for at least 10–15 minutes so every inch of the oven is very hot.

Whisk the 3 remaining Tablespoons of olive oil with the minced garlic and herbs. Set aside.

Using your fingers, dimple the dough all over the surface. You can watch me do this in the video above. Drizzle on the olive oil topping and use your hands or a pastry brush to spread it all over the top. Add a little more olive oil if needed so the dough is completely covered. (This creates the crisp crust!) Sprinkle with a little coarse salt and freshly ground black pepper.

Bake for 20–23 minutes or until lightly browned on top. If desired, broil on high for the last minute to really brown the top.

Cut and serve hot or let it come to room temperature before slicing and serving. Focaccia tastes wonderful warm or at room temperature. Cover leftover focaccia tightly and store at room temperature for 2 days or in the refrigerator for 1 week. You can also freeze the baked and cooled focaccia for up to 3 months. Thaw in the refrigerator or at room temperature. To reheat the slices, you can use the microwave or bake in a 300°F (149°C) oven for 5 minutes.
