In a large mixing bowl, combine the warm water, sugar, and instant yeast. Let it sit for about 5 minutes or until bubbly and foamy.
Add the all-purpose flour, salt, and ¼ cup of olive oil to the yeast mixture. Stir with a wooden spoon until a rough dough forms.
Transfer the dough to a lightly floured surface and knead for about 5-7 minutes until smooth and elastic.
Place the dough in a greased bowl, cover it with a damp cloth, and let it rise in a warm place for 1 hour or until doubled in size.
Once risen, punch down the dough and transfer it to a parchment-lined baking sheet. Press it gently into a rectangle or circle, about ½ inch thick.
Using your fingers, create dimples all over the surface of the dough. Drizzle olive oil generously over the top, and then sprinkle the minced garlic, rosemary, thyme, and coarse sea salt evenly.
Cover the dough loosely with a towel and let it rest for another 30 minutes while preheating your oven to 400°F (200°C).
Bake the focaccia for 20-25 minutes or until golden brown and crispy on the edges.
Remove from the oven and let it cool for a few minutes before slicing.
Notes
For extra flavor, let the dough rise longer if time permits.
