In a large bowl, combine water, yeast, and sugar. Whisk until dissolved and let sit until yeast foams, 5 minutes.

Add 2 cups flour to bowl and whisk for 2 minutes, until completely smooth and the texture of pancake batter. Add remaining flour and salt, and stir vigorously with a wooden spoon for about 2 minutes, until all flour is incorporated and dough begins to pull away from the sides of the bowl as you stir. Cover bowl with plastic wrap or a clean kitchen towel and let rise until doubled in size, 30 to 40 minutes. (An off oven or microwave is a great place to proof dough!) Alternatively: refrigerate dough overnight to develop flavor. When ready to bake, remove bowl 2 hours in advance and let stand, covered, in a warm place before proceeding to next step.

Preheat oven to 500° and add 1 tablespoon oil to a metal 9”-x-13” baking pan. Use your fingers to coat all edges of the pan with oil, then sprinkle 2 tablespoons everything seasoning in an even layer at the bottom of your baking dish. Cut the top off head of garlic, leaving the root intact. Place on a square of aluminum foil, drizzle with teaspoon oil, and wrap completely in foil.

When dough has doubled in size, carefully transfer your dough to prepared baking sheet, using a rubber spatula to detach dough from bowl. (The dough will be very wet. Avoid touching it at this point, as it is extremely sticky.)

Drizzle remaining ¼ cup olive oil all over dough, then oil your hands. Plunge the tips of your fingers into the dough, all the way to the bottom of the pan, and drag outward to stretch dough to edges of the pan, creating small dimples all over. Sprinkle remaining everything seasoning over dough and top with a generous sprinkling of flaky sea salt.

Place focaccia and wrapped garlic head in oven and reduce temperature to 450°. Bake until bread is golden and garlic is tender, 20 to 25 minutes. Let focaccia cool at least 10 minutes before slicing.

For garlic cream cheese: in a medium bowl, combine cream cheese and all roasted garlic cloves. Season with salt and mash with a fork until smooth.
