Ingredients
Caramelized onion focaccia – super fluffy focaccia topped with caramelized onions, fresh thyme, and garlic. This easy no-knead yeast bread makes a delicious appetizer or as a side dish to your favorite meal!
- 2 tbsp olive oil
- 1 tbsp salted butter
- 4 cups diced yellow onions
- 1/4 cup water
- 2 tbsp fresh thyme (chopped)
- 2 1/2 cups all purpose flour (see notes below for measuring)
- 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
- 1/4 cup olive oil
- 3 whole garlic cloves (crushed)
How to Make Caramelized Onion Focaccia
Step 1: Caramelize the Onions
Melt the butter and olive oil in a large skillet over medium heat. Stir in the onions. Add the water and cover until the onions have softened, about 5 minutes. Remove the cover and reduce the heat to medium-low. Stir frequently so they don’t burn! Cook for about 1 hour until deeply caramelized. Transfer them to a bowl and stir in fresh thyme.
Step 2: Prepare the Dough
In a large bowl, combine the flour, lukewarm water, parmesan cheese, olive oil, sugar, yeast, and salt. Use a wooden spoon to mix everything together until fully combined.
Step 3: Let the Dough Rise
Lightly oil your hands and another large bowl. Place the dough into this oiled bowl and cover with plastic wrap. Set it in a warm place to rise until doubled in size (about 1 hour).
Step 4: Make Garlic Oil
While the dough rises, heat olive oil in a skillet. Stir in crushed garlic and cook for about 5 minutes until fragrant. Remove the garlic from the oil and let it cool before using.
Step 5: Preheat Oven
Preheat your oven to 425°F (220°C). Pour half of the garlic oil into an unlined metal baking pan (9×9) and set aside.
Step 6: Stretch the Dough
Once risen, lightly oil your hands again. Stretch each section of dough upward then fold toward the center. Transfer seam-side down into the oiled baking pan. Cover again with plastic wrap and let rise another hour until doubled.
Step 7: Prepare for Baking
After rising again, check that your dough is jiggly with large bubbles filling almost all of the pan.
Step 8: Bake It!
Pour remaining garlic oil over top of dough. Use your fingers to press down creating deep dimples. Sprinkle with fresh thyme before placing it in the oven. Bake immediately for about 12-18 minutes until golden brown on top with an internal temperature of at least 190°F (88°C).
Step 9: Add Toppings & Cool Down
Once out of the oven, spoon caramelized onions atop hot focaccia. Allow it to cool on a wire rack before sprinkling flaky sea salt and extra thyme if desired. Cut into servings when cool enough.
Step 10: Storage Tips
Focaccia tastes best when served fresh but can be stored in an airtight container in the fridge. For longer storage, tightly wrap leftovers in plastic wrap then foil; freeze for up to one month. Reheat gently in microwave or oven before serving again.
Now you’re ready to impress friends and family with this delicious caramelized onion focaccia! Enjoy every bite!

Common Mistakes to Avoid
Making Caramelized Onion Focaccia can be easy, but some common mistakes can hinder your results. Here are a few to watch out for:
- Overcooking the onions: Ensure that you cook the onions slowly and stir them frequently to avoid burning. Aim for a deep golden color for the best flavor.
- Ignoring dough rising times: Allowing the dough to rise properly is crucial. If you’re in a hurry, avoid rushing this step as it affects the bread’s fluffiness.
- Using cold water: Always use lukewarm water when mixing your dough. Cold water can slow down yeast activation, leading to poor rising.
- Not measuring flour accurately: Use the right method to measure flour, as too much can result in dense focaccia. Spoon flour into your measuring cup and level it off.
- Skipping the garlic oil: The garlic oil adds flavor; don’t skip this step! It enhances the focaccia’s taste and creates a delicious crust.
