Why Make This No Knead Sourdough Focaccia With Mushrooms And Thyme Bubbly

This recipe is the ultimate “set it and forget it” bread. Because it requires no kneading, you let time and fermentation do all the heavy lifting. The high hydration levels ensure those iconic giant bubbles, while the sourdough starter adds a complex depth of flavor that store-bought yeast simply cannot match. It is the perfect way to use your active starter, and the combination of mushrooms and thyme provides a sophisticated, umami-packed profile that pairs beautifully with soups, salads, or just a glass of wine.

Ingredients

100g active sourdough starter (bubbly and fed)
375g warm water
500g bread flour (or all-purpose flour)
10g fine sea salt
20g extra virgin olive oil (plus extra for the pan and drizzling)
200g cremini or shiitake mushrooms, thinly sliced
3-4 sprigs of fresh thyme, leaves stripped
Flaky sea salt for finishing
1 tablespoon balsamic vinegar (optional, for the mushrooms)

Directions

Step 1: Mix the Dough

In a large mixing bowl, whisk together the active sourdough starter and warm water until the starter mostly dissolves. Add the flour and sea salt. 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 allow the flour to hydrate.

Step 2: Stretch and Fold

After the rest, perform a series of stretch and folds. Wet your hand, grab one side of the dough, pull it up high, and fold it over into the center. Rotate the bowl and repeat this 4 times. Perform three more sets of these folds every 30 minutes. This builds strength in the dough without any kneading. After the final set, cover the bowl and let the dough rise at room temperature for 4 to 6 hours, then move it to the fridge overnight (12-14 hours) for the best flavor.

Step 3: Prepare the Mushrooms

While the dough finishes its cold proof, sauté the sliced mushrooms in a pan with a splash of olive oil over medium-high heat. Cook until they are golden brown and have released their moisture. Stir in the balsamic vinegar if using, and a pinch of salt. Remove from heat and let them cool completely before topping the dough.

Step 4: The Pan Proof

Generously coat a 9×13 inch baking pan with olive oil. Gently transfer the cold dough into the pan. Do not force it to the corners yet. Flip the dough once to coat both sides in oil. Cover and let it proof in a warm spot for 2 to 4 hours. The dough is ready when it has spread to the edges and looks very jiggly and full of air bubbles.

Step 5: Dimple and Top

Preheat your oven to 425°F (220°C). Drizzle more olive oil over the top of the proofed dough. Use your fingertips to press straight down into the dough to create deep dimples all over. Scatter the sautéed mushrooms and fresh thyme leaves across the surface. Sprinkle generously with flaky sea salt.

Step 6: Bake and Serve

Place the pan in the oven and bake for 20 to 25 minutes, or until the top is deeply golden brown and the bottom is crisp. If you want an extra-crispy bottom, you can carefully slide the focaccia out of the pan and onto the oven rack for the last 2 minutes. Transfer to a wire rack to cool for at least 10 minutes before slicing. This keeps the bottom from getting soggy.

Expert Tips for Perfect No Knead Sourdough Focaccia With Mushrooms And Thyme Bubbly

For the biggest bubbles, ensure your starter is at its peak activity when you mix the dough. Use a high-quality extra virgin olive oil, as the flavor truly shines in this bread. If your kitchen is cold, the final proof in the pan might take longer; look for the dough to look “alive” and jiggly. Also, make sure your mushrooms are cooked and cooled before adding them; raw mushrooms release too much water and can make the top of your focaccia gummy.

Delicious Variations

You can easily customize this focaccia to suit your cravings. Add a sprinkle of shredded parmesan or gruyère cheese during the last 5 minutes of baking for a salty crust. Swap the thyme for rosemary if you prefer a piney aroma. For a bit of sweetness, drizzle some honey or a balsamic reduction over the finished bread. You can also add caramelized onions alongside the mushrooms for a “French Onion” style twist.

Frequently Asked Questions

Can I use sourdough discard instead of active starter?
For this specific no-knead recipe, an active, bubbly starter is best to ensure the bread rises properly and gets those big bubbles. Using discard may result in a denser, flatter loaf.

What is the best way to store leftovers?
Store leftovers in an airtight container at room temperature for up to 2 days. To refresh, toast the slices in a dry skillet or a toaster oven until the crust is crisp again.

Why didn’t my dough develop large bubbles?
This usually happens if the dough didn’t proof long enough or if the starter wasn’t active enough. Make sure the dough is doubled in size and looks very bubbly before you dimple it.

Can I bake this in a cast iron skillet?
Yes! A large cast iron skillet works wonderfully for focaccia and usually produces an even crispier, fried-bottom texture. Just ensure it is well-oiled.

How do I know when the focaccia is finished baking?
The top should be a dark golden brown, and the edges should be pulling away slightly from the pan. You can also lift a corner with a spatula; the bottom should be golden and firm.
