Cosi Flatbread Recipe: Wood-Fired Crust at Home

I’ve spent years perfecting flatbread that captures the essence of wood-fired baking at home. This recipe delivers a crisp yet chewy crust with minimal effort and maximum flavor.

The secret lies in high heat and a simple dough that comes together in minutes. No special equipment needed—just your oven and a baking stone or sheet pan.

What emerges is a golden, blistered flatbread with a tender interior, ready for toppings or to enjoy plain. The aroma alone will transport you to a rustic Italian kitchen.

Perfect for appetizers, sandwiches, or as a side to any meal. Here’s how to achieve that signature texture every time.

Ingredients for Cosi Flatbread

A handful of pantry staples transforms into golden, blistered flatbread with ease.

The flour is non-negotiable here. Bread flour (I like King Arthur) gives you that chewy, elastic texture that mimics wood-fired results. Yeast should be fresh—check the expiration date. If your sugar is lumpy, dissolve it in the warm water first. Diamond Crystal kosher salt is my go-to for consistent seasoning, but any fine salt works in a pinch.

No bread flour? All-purpose plus 1 tbsp vital wheat gluten per cup gets you close. Short on olive oil? Melted butter (cooled) works, though it changes the flavor slightly. The semolina and cornmeal add crunch—skip if you must, but they’re worth hunting down at Whole Foods or a bulk bin store. Rosemary isn’t traditional, but I love the aromatic touch.

Dough keeps in the fridge 24-48 hours—let it come to room temp before shaping. Baked flatbreads are best eaten fresh but reheat beautifully in a dry skillet. Freeze dough balls for up to 1 month (thaw overnight in the fridge).

Step-by-Step Instructions for Cosi Flatbread

Here’s my tested method for achieving that signature crisp-yet-chewy crust with minimal effort.

Step 1: Activate the Yeast and Mix the Dough

In a small bowl, whisk together the 1.25 cups warm water, 1 tsp granulated sugar, and 1 tsp active dry yeast. Let it sit for 5-7 minutes until the mixture becomes foamy and cloudy—that’s how you know the yeast is active and ready to work.

In a large mixing bowl, combine the 3 cups bread flour and 1.5 tsp kosher salt. Make a well in the center and pour in the yeast mixture along with the 2 tbsp extra-virgin olive oil. Use a wooden spoon to stir until a shaggy dough forms, then switch to your hands to bring it all together.

Step 2: Knead and First Rise

Turn the dough out onto a lightly floured surface and knead for 8-10 minutes until smooth and elastic. You’ll know it’s ready when it springs back slowly when poked with a finger. The high-protein bread flour gives it that perfect chewiness.

Lightly oil a clean bowl with some extra-virgin olive oil, place the dough inside, and turn to coat. Cover with a damp towel and let it rise in a warm spot for 1-2 hours, or until doubled in size. This first rise develops the gluten and flavor.

Step 3: Shape and Second Rise

Punch down the risen dough to release the air, then divide it into 4 equal portions. Shape each into a ball and let them rest on a surface dusted with 0.25 cup semolina flour for 15-20 minutes. The semolina prevents sticking and adds a nice texture to the crust.

After resting, use your hands or a rolling pin to stretch each ball into an oval shape, about ⅛-inch thick. The dough might spring back at first—just let it relax for a few minutes and try again. This thinning step is crucial for that authentic flatbread texture.

Step 4: Bake on a Hot Surface

Preheat your oven to 500°F with a baking stone or inverted baking sheet inside. Sprinkle 2 tbsp cornmeal on a pizza peel or another inverted baking sheet to prevent sticking. Transfer one piece of shaped dough onto the cornmeal-dusted surface.

Slide the dough onto the preheated stone and bake for 8-10 minutes until the edges are golden brown and the flatbread puffs slightly. For that wood-fired look, broil for 1-2 minutes at the end, watching closely to avoid burning.

Step 5: Finish and Serve

Remove the flatbread from the oven and immediately brush the top with a little extra-virgin olive oil. Sprinkle with 1 tbsp chopped fresh rosemary and 0.5 tsp flaky sea salt for that final gourmet touch. The rosemary adds a fragrant, earthy note that complements the crispy crust perfectly.

Let it cool for 2-3 minutes before slicing. Serve warm for the best texture—the outside should be crisp while the inside stays soft and chewy. Repeat with the remaining dough portions, adjusting bake time as needed based on your oven’s hot spots.

Creative Variations of These Flavors

Herb-Infused Version

Mix 1 tbsp chopped fresh rosemary and 1 tsp dried oregano into the dough during kneading. The herbs infuse every bite with fragrant Mediterranean notes. I tested this variation three times to perfect the herb-to-dough ratio. 🌿

Garlic & Cheese

Before baking, brush dough with 2 tbsp garlic-infused olive oil and sprinkle ½ cup grated Parmesan. The garlic adds pungent depth while the cheese creates golden, crispy patches. Use Parmesan Reggiano from my neighborhood Italian deli for best results.

Spicy Calabrian

Spread 1 tbsp Calabrian chili paste on dough before baking for a kick. Top with ¼ cup crumbled feta and thin-sliced red onions. The heat balances beautifully with the creamy feta. I discovered this combo after a particularly memorable meal in Boston.

Sweet Breakfast

Drizzle baked flatbread with 2 tbsp honey and sprinkle with ¼ cup chopped walnuts and ½ tsp cinnamon. Serve warm with fresh ricotta. This variation reminds me of Sunday mornings in my Nonna’s kitchen. 💛

Everything Bagel

Brush with 1 tbsp olive oil and sprinkle 2 tbsp everything bagel seasoning before baking. The sesame, poppy, and garlic flakes create a savory crunch. I keep a jar of this seasoning blend in my pantry at all times.

Mediterranean Style

Top with ¼ cup sliced olives, 2 tbsp chopped sun-dried tomatoes, and 1 tbsp capers. Bake as usual, then finish with a drizzle of balsamic glaze. The briny, tangy flavors transport you straight to the coast.
