Why Make This Sourdough Focaccia No Knead Overnight Bubbles
This recipe is a game-changer for busy bakers. Because it is a “no-knead” dough, you avoid the messy countertop cleanup and the physical fatigue of traditional bread making. The overnight cold ferment in the refrigerator develops a complex flavor profile that quick breads simply cannot match. Furthermore, the high hydration levels ensure those photogenic bubbles that make focaccia so famous. It is the perfect low-effort, high-reward bake for any skill level.
Ingredients
- 100g active sourdough starter (bubbly and fed)
- 375g warm water
- 500g bread flour (or high-protein all-purpose flour)
- 10g fine sea salt
- 20g extra virgin olive oil (for the dough)
- Additional olive oil for the pan and drizzling
- Flaky sea salt for topping
- Fresh rosemary sprigs (optional)
Directions
Step 1: Mix the Dough
In a large glass bowl, whisk together your active sourdough starter and warm water until the starter mostly dissolves. Add the flour, sea salt, and 20g of olive oil. Use a sturdy spatula or your hands to mix until a shaggy dough forms and no dry flour remains. Cover the bowl with a damp cloth or plastic wrap and let it rest for 30 minutes to autolyse.
Step 2: Stretch and Fold
Wet your hands to prevent sticking. Reach under one side of the dough, pull it upward, and fold it over the center. Rotate the bowl and repeat this 4 times until you have completed a full circle. This builds the gluten structure without kneading. Perform three sets of these folds, spaced 30 minutes apart. After the final set, the dough should look smoother and more elastic.
Step 3: Overnight Fermentation
Cover the bowl tightly with plastic wrap or a lid. Place the dough in the refrigerator for 12 to 18 hours. This cold fermentation slows down the yeast, allowing the gases to build up slowly and create those beautiful bubbles while intensifying the sourdough tang.
Step 4: Pan Proofing
Generously coat a 9×13 inch metal baking pan with olive oil. Gently tip the cold dough into the pan. Do not force it to the corners yet. Flip the dough once so it is coated in oil. Cover it and let it rise at room temperature for 2 to 4 hours. The dough is ready when it has filled the pan and looks jiggly and full of air bubbles.
Step 5: Dimpling and Baking
Preheat your oven to 425°F (220°C). Drizzle the top of the dough with more olive oil. Grease your fingers and press them straight down into the dough to create deep dimples. Watch the bubbles rise! Sprinkle with flaky salt and rosemary. Bake for 20-25 minutes until the top is golden brown and the bottom is crispy. Remove from the pan immediately and cool on a wire rack.
Expert Tips for Perfect Sourdough Focaccia No Knead Overnight Bubbles
Use a metal pan instead of glass for the crispiest bottom crust. If your dough resists stretching to the corners during the pan proofing stage, let it rest for another 15 minutes to relax the gluten, then try again. Always use wet fingers when dimpling to prevent the dough from tearing or sticking to your skin. For the best bubbles, ensure your starter is at its peak activity before mixing the dough.

Delicious Variations
- Garlic and Herb: Press sliced garlic cloves and fresh thyme into the dimples before baking.
- Tomato and Feta: Top with halved cherry tomatoes and crumbled feta cheese for a Mediterranean twist.
- Caramelized Onion: Spread a layer of balsamic caramelized onions over the dough before the final dimpling.
- Pesto Swirl: Dollop small spoonfuls of basil pesto across the surface and swirl them in with a toothpick.
Frequently Asked Questions
Can I use sourdough discard?
For the best rise and bubbles, an active starter is recommended. However, you can use discard if you add a 1/2 teaspoon of commercial yeast to help the fermentation process.
What if my dough isn’t bubbling?
Bubbles usually indicate a strong gluten network and proper fermentation. Ensure your room is warm enough during the final proof, or extend the proofing time until you see visible air pockets.
How do I store leftover focaccia?
Store it in an airtight container at room temperature for up to 2 days. To revive the crunch, toast it in a 350°F oven for a few minutes.
Why did my focaccia stick to the pan?
Focaccia requires a lot of oil. Ensure you use a high-quality non-stick pan or a well-seasoned cast iron, and don’t be afraid to use a generous amount of olive oil on the bottom.
Can I ferment the dough for longer than 18 hours?
Yes, you can leave it in the fridge for up to 72 hours. The flavor will become much more sour and the dough will become more fragile as the acid breaks down the gluten.

Mastering the Sourdough Focaccia No Knead Overnight Bubbles recipe is a rewarding journey that fills your kitchen with an incredible aroma.
