Ingredients

(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)

For the Dough

4 cups all-purpose or bread flour
2¼ teaspoons active dry yeast
1¾ cups warm water
2 teaspoons salt
2 tablespoons olive oil
1 teaspoon granulated sugar

For the Topping

2 large yellow onions, thinly sliced
2 tablespoons olive oil
1 teaspoon fresh thyme leaves (or ½ teaspoon dried thyme)
1 teaspoon flaky sea salt
Freshly ground black pepper
Extra olive oil for drizzling

Directions

I dissolve the yeast and sugar in the warm water and let the mixture sit for about 5 to 10 minutes until it becomes foamy.
I combine the flour, salt, olive oil, and yeast mixture in a large bowl, then mix until a soft dough forms.
I knead the dough until it becomes smooth and elastic, then place it in a lightly oiled bowl to rise until doubled in size, about 1 to 2 hours.
While the dough rises, I heat the olive oil in a skillet and slowly cook the onions over medium-low heat for 30 to 40 minutes, stirring occasionally, until they become soft and deeply caramelized. I stir in the thyme during the last few minutes of cooking.
I grease a baking pan generously with olive oil and gently stretch the risen dough into the pan.
I let the dough rise again for about 30 to 45 minutes until it becomes puffy.
I use my fingertips to create dimples across the surface of the dough.
I drizzle the dough with olive oil and evenly distribute the caramelized onions over the top. I finish with flaky sea salt and black pepper.
I bake the focaccia in a preheated 425°F (220°C) oven for 22 to 28 minutes, or until the bread is golden brown.
I let the focaccia cool slightly before slicing and serving.

Servings and Timing

Servings: 12 slices
Prep Time: 20 minutes
Rise Time: 2 hours 15 minutes
Cook Time: 30 minutes
Total Time: About 3 hours 5 minutes

Variations

I sprinkle grated Parmesan or Pecorino cheese over the onions before baking.
I add fresh rosemary along with the thyme for extra aroma.
I top the bread with sliced olives for a Mediterranean-inspired version.
I include roasted garlic cloves for deeper savory flavor.
I add crumbled goat cheese after baking for a creamy finish.
I sprinkle red pepper flakes on top for a little heat.

Storage/Reheating

I store leftover focaccia in an airtight container or wrap it tightly at room temperature for up to 2 days. For longer storage, I freeze individual slices for up to 3 months. When I am ready to enjoy it again, I reheat the bread in a 350°F (175°C) oven for about 8 to 10 minutes until it is warm and the crust becomes crisp again.

FAQs

Can I make the dough ahead of time?

Yes. I often let the dough rise overnight in the refrigerator, which also helps develop even more flavor.

Why should I caramelize the onions slowly?

I cook the onions over low heat because it allows their natural sugars to develop, creating a rich, sweet flavor without burning them.

Can I use bread flour instead of all-purpose flour?

Yes. I prefer bread flour when I want an even chewier texture and a slightly higher rise.

How do I know when the focaccia is done?

I look for a deep golden-brown crust, and the bottom of the bread should sound hollow when tapped.

What can I serve with caramelized onion focaccia?

I enjoy serving it with soups, salads, pasta, charcuterie boards, olive oil and balsamic vinegar, or using it as the base for delicious sandwiches.

Conclusion

I love making this Caramelized Onion Focaccia because it delivers incredible flavor with a wonderfully soft interior and crisp, golden crust. The sweet caramelized onions and fragrant herbs make every slice feel special, whether I serve it fresh from the oven or enjoy the leftovers the next day. It’s a homemade bread that’s as impressive as it is comforting.
