In a large bowl, combine the warm water, active dry yeast, and granulated sugar. Let the mixture rest for about 5 minutes until it becomes foamy and fragrant.

In a separate bowl, whisk together half of the olive oil, minced garlic, and kosher salt. Once combined, add this mixture to the yeast mix, stirring gently.

Gradually stir in all-purpose flour until a soft dough forms. Transfer it to a greased bowl, cover with a kitchen towel, and let it rise in a warm spot for about 1 hour, or until doubled in size.

Heat the remaining olive oil and butter in a skillet over medium heat. Add the sliced yellow onions and granulated sugar, cooking for approximately 20 minutes until the onions are soft, golden brown, and fragrant. Stir occasionally to prevent burning.

Preheat your oven to 450°F. Pour the remaining oil mixture into a baking dish, then gently stretch the risen dough to fit, creating dimples with your fingers. Top with salt, caramelized onions, and shredded white cheddar cheese. Bake for 18-20 minutes until the bread is golden brown and the cheese is bubbly.

Slice into squares or rectangles and enjoy the warm, cheesy delight fresh out of the oven!
