How to Make Caramelized Onion Focaccia
-
Sauté the Onions: In a large skillet over medium heat, melt the butter with olive oil. Stir in the diced onions and water, covering the skillet until they soften—about 5 minutes. Then, uncover and reduce the heat to medium-low, stirring frequently for about 1 hour until the onions are deeply caramelized. Mix in fresh thyme when done.
-
Mix the Dough: In a large bowl, combine flour, lukewarm water, parmesan cheese, olive oil, sugar, yeast, and salt. Mix everything together with a wooden spoon until fully combined and forms a dough.
-
Let it Rise: Lightly oil your hands and a separate bowl, placing the dough into it. Cover the top with plastic wrap and set it in a warm spot to rise until doubled in size, roughly 1 hour.
-
Prepare Garlic Oil: While the dough rises, heat olive oil in a skillet, adding the crushed garlic cloves. Cook for about 5 minutes until fragrant and slightly browned. Remove the garlic and discard; let the aromatic oil cool.
-
Preheat the Oven: Set your oven to 425°F (220°C). Pour half of the cooled garlic oil into an unlined 9×9 metal baking pan, spreading it evenly.
-
Shape the Dough: Once the dough has risen, lightly oil your hands. Grab the dough from the top, stretch it upward, fold it towards the center, and repeat for each side. Place the dough seam side down into the oiled pan, cover with plastic wrap, and let it rise for another hour until doubled.
-
Dimple and Bake: After the second rise, the dough will be puffy with bubbles. Pour the remaining garlic oil over the dough and use your fingers to create deep dimples. Sprinkle fresh thyme, then bake in the oven for 12-18 minutes, until golden brown with an internal temperature of at least 190°F (88°C).
-
Top and Cool: Remove the focaccia from the oven and spoon the caramelized onions on top. Cool on a wire rack before cutting. Optionally, sprinkle with flaky sea salt and extra thyme before serving.
Optional: Serve warm with a drizzle of additional olive oil for extra flavor.

Expert Tips for Caramelized Onion Focaccia
Timing is Key: Allow sufficient time for caramelizing the onions—this deepens their flavor significantly and prevents them from burning.
Gentle Mixing: When combining the focaccia dough ingredients, avoid over-mixing. A gentle hand helps maintain a softer texture in your Caramelized Onion Focaccia.
Warm Environment: To achieve the best rise, place your dough in a warm spot—drafts can slow the fermentation process and yield a denser bread.
Dimpling Technique: Don’t skip making dimples with your fingers before baking! This not only looks beautiful but also helps the oil seep into the dough for extra flavor.
Baking Watch: Keep an eye on your focaccia in the last few minutes of baking. Every oven is different, and a golden brown top is your cue for perfection.
How to Store and Freeze Caramelized Onion Focaccia
Room Temperature: Store leftover focaccia in an airtight container at room temperature for up to 3 days. This keeps it fresh and soft, ready for snacking or meals.
Fridge: For longer storage, wrap the focaccia in plastic wrap and place it in the fridge, where it will last for up to a week. Reheat slices in the oven to restore warmth and texture.
Freezer: Slice your focaccia and store it in a freezer-safe bag or container for up to 3 months. Thaw it overnight in the fridge and reheat in the oven for the best results.
Reheating: To enjoy your focaccia warm, preheat the oven to 350°F (175°C) and heat for about 10-15 minutes, or until warmed through. This rejuvenates the lovely flavors and aroma of the caramelized onion focaccia.
Caramelized Onion Focaccia Recipe FAQs
How do I choose the right onions for caramelizing?
Selecting the right onions is crucial for achieving that perfect sweetness! I recommend using yellow onions, as they have the best flavor for caramelization. Look for onions that feel heavy for their size and have a firm outer skin without dark spots or soft areas. The sweetness will be amplified with proper cooking, so don’t rush the process!
How should I store my leftover Caramelized Onion Focaccia?
Absolutely! To keep your focaccia fresh, store it in an airtight container at room temperature for up to 3 days. If you’d like it to last longer, wrap it in plastic wrap and place it in the fridge for about a week. That way, you can savor that deliciousness a little longer!
Can I freeze Caramelized Onion Focaccia?
Yes! This focaccia freezes beautifully. Slice it before freezing to make future reheating easy. Just place the slices in a freezer-safe bag or container, and it will last up to 3 months in the freezer. When you’re ready to enjoy, thaw it overnight in the fridge, then reheat in a 350°F (175°C) oven for about 10–15 minutes for the best texture.
What can I do if my dough isn’t rising?
If your dough isn’t rising, don’t worry—just check a few things! First, ensure that your yeast is fresh and effective; if you’re using instant yeast, it should bubble when mixed with warm water and sugar. If your home is too cold, try placing the dough in a warmer spot, such as an oven set to the lowest temperature or near a sunny window. Give it time—sometimes it just needs a little extra love!
Is this focaccia suitable for those with gluten allergies?
This particular recipe isn’t gluten-free, but you can adapt it! Substitute all-purpose flour with a gluten-free flour blend that is ideal for baking. Be sure to include a binding agent like xanthan gum, as it helps replicate the texture of traditional focaccia. Always take care to check the ingredient labels for any hidden allergens that might affect you or your guests.
