This Caramelized Onion Focaccia is a savory Italian flatbread featuring deeply caramelized yellow onions, fresh thyme, and a perfect blend of olive oil and parmesan cheese. Soft, fluffy, and golden with a beautifully dimpled crust, it delivers sweet, aromatic onion flavor balanced with herbaceous notes. Ideal as an appetizer, side, or snack, it’s baked to a golden perfection in a 9×9 pan and topped with garlic-infused oil for added depth.

Ingredients

Scale

Caramelized Onions

  • 2 tbsp olive oil
  • 1 tbsp salted butter
  • 4 cups diced yellow onions
  • 1/4 cup water
  • 2 tbsp fresh thyme, chopped

Dough

  • 2 1/2 cups all purpose flour
  • 1 1/4 cup lukewarm water
  • 1/4 cup parmesan cheese, finely shredded
  • 2 tbsp olive oil
  • 1 tbsp granulated sugar
  • 2 tsp instant yeast
  • 3/4 tsp salt
  • 1–2 tbsp fresh thyme

Garlic Oil

  • 1/4 cup olive oil
  • 3 whole garlic cloves, crushed

Instructions

  1. Caramelize the Onions: Melt butter and olive oil in a large skillet over medium heat. Add the diced onions and water, cover, and cook until softened, about 5 minutes. Remove lid and reduce heat to medium-low, stirring frequently to prevent burning. Cook about 1 hour until onions are deeply golden and caramelized. Transfer to a bowl and stir in chopped fresh thyme.
  2. Prepare the Dough: In a large bowl, combine flour, lukewarm water, parmesan cheese, olive oil, sugar, instant yeast, and salt. Mix thoroughly with a wooden spoon until fully combined.
  3. First Proofing: Lightly oil your hands and a large bowl. Place the dough in the bowl, cover with plastic wrap, and set in a warm place to rise until doubled in size, about 1 hour.
  4. Make Garlic Oil: Heat olive oil in a skillet, add crushed garlic cloves, and cook for about 5 minutes until fragrant and starting to brown. Remove and discard garlic cloves. Let the garlic-infused oil cool.
  5. Prepare Pan and Preheat Oven: Preheat oven to 425°F (220°C). Pour half of the garlic oil into an unlined 9×9-inch metal baking pan and set aside.
  6. Shape the Dough: Once the dough has doubled, lightly oil your hands. Stretch the top sections of the dough upward and fold each side toward the center, repeating with all four sides. Transfer the dough seam-side down into the oiled baking pan. Cover with plastic wrap and let rise again in a warm place until doubled, about 1 hour.
  7. Check Dough Rise: After the second rise, the dough should be jiggly with large bubbles and nearly fill the pan.
  8. Add Garlic Oil and Dimples: Pour the remaining garlic oil over the dough. Using your fingers, press straight down to create deep dimples. Sprinkle fresh thyme over the surface. Bake immediately in the preheated oven for 12-18 minutes until golden brown and reaching an internal temperature of at least 190°F (88°C).
  9. Finish With Caramelized Onions: Remove focaccia from the oven and spoon the caramelized onions evenly over the top. Allow to cool in the pan on a wire rack. Once cool, sprinkle with flaky sea salt and additional fresh thyme if desired. Slice and serve.
  10. Storage: Best eaten the day it’s made. Store leftovers in an airtight container in the refrigerator or wrap tightly in plastic wrap and foil to freeze up to one month. Reheat in the microwave or oven until warmed through before serving.

Notes

  • Use a metal 9×9 inch baking pan for best results and proper baking.
  • To measure flour accurately, spoon flour into measuring cup and level off with a knife (rather than scooping directly).
  • Ensure onions are deeply caramelized for optimum flavor—this takes about 1 hour with frequent stirring to prevent burning.
  • Garlic cloves are removed after infusing oil to avoid overpowering sharpness.
  • Fresh thyme can be adjusted to taste and used both in the dough and as a topping.
  • Check internal temperature to ensure focaccia is fully baked.
