Nothing beats the freshness of a homemade focaccia, and it's one of the easiest breads you can make yourself! This one is topped with caramelized onions and shredded gruyere cheese for delicious flavor.
Place the yeast, water, and sugar in the bowl of a stand mixer, and let it sit for 5 minutes until foamy. Add in the flour, salt, and 1/4 cup olive oil and mix it up by hand or with the paddle attachment. Attach the dough hook and knead for 10 minutes on medium low. Cover the bowl and let the foccacia rise for 1 hour.
In the meantime, chop the onion and cook it in 2 tbsp olive oil. Season with a pinch of salt and pepper, and cook over medium heat for about 15 minutes until translucent and then slightly caramelized.
Preheat the oven to 400 degrees F.
Spread the remaining 2 tbsp olive oil all over a sheet pan, and add the focaccia dough. Stretch the dough to the sides with your hands, poking little holes with your fingers. Add the caramelized onion evenly over the top, as well as the gruyere. Finish it off with a sprinkling of coarse sea salt and cracked black pepper, and bake for 15 minutes.
