Onion and Nduja Focaccia
Combining the sweet caramelised edges of roasted onion with the fiery punch of nduja, this focaccia brings warmth, depth, and a hint of indulgence to your table. Grated Grana Padano and Parmesan melt into the golden crust, adding richness and savoury umami, while a drizzle of good extra virgin olive oil and a sprinkle of dried oregano bring everything together in true Italian fashion.
Nduja, for the uninitiated, is a spicy, spreadable pork salume from Calabria. It melts beautifully into the dough as it bakes, infusing the loaf with pools of heat and savoury depth. When paired with lightly charred onion rings and crispy cheese, you get a focaccia that’s both chewy and crispy, bold yet balanced.
This one’s perfect served warm alongside a bowl of soup, sliced up for sandwiches, or torn apart and dipped in more olive oil (trust us).




Onion and Nduja Focaccia
Equipment
- Pizza Steel, or Stone
- Medium Ooni Detroit Style pan (32.4 x 24.1 x 5.9 cm) or similar
- 1 wooden chopping board or peel for prep and serving
Ingredients
- 1 focaccia dough
- Nduja
- Brown onion
- Grana Padano cheese
- Parmesan cheese
- Dried oregano
- Extra virgin olive oil
Instructions
- Prepare Dough: You can follow any of our dough recipes. We used our cold fermentation dough recipe for this particular bake. You will need to prepare the dough at least 24 hours ahead of time.
- Prepare Cheese: Grate both the Grana Padano and Parmesan cheeses and set aside in a bowl, ready for assembly.
- Prepare Onion: Slice onion into thin rings. Set aside for topping.
- Prepare Nduja:Break nduja into small chunks or dollops using a spoon. No need to cook beforehand, it will melt beautifully into the focaccia during the bake.
- Preheat Home Oven with Pizza Steel:Place a pizza steel or stone inside the oven and preheat to 250°C (482°F) for at least 30 minutes.
- Prepare Base: After cold fermentation, transfer the dough to a well-oiled tray or pan (we recommend the medium Ooni Detroit Style pan, 32.4 x 24.1 x 5.9 cm). Drizzle extra virgin olive oil (EVOO) over the top and begin to gently press and stretch the dough, pulling from underneath until it nearly reaches the edges of the pan.Cover and proof for another 15-20 minutes to allow the dough to relax and expand further.After proofing, press and stretch again until the dough comfortably reaches the edges of the pan. Drizzle with a little more EVOO, then use your fingertips to create dimples across the surface.
- Assemble Focaccia: Sprinkle a light layer of the grated cheeses over the surface of the dough.Evenly distribute the sliced onions and nduja over the dough.Add a generous sprinkle of both cheeses.Sprinkle with dried oregano and a generous drizzle of EVOO.
- Bake Your Focaccia:Bake at 250°C (482°F) for ~20 minutes, or until golden brown and crisp on top.
- Serving: Once baked, remove the focaccia from the oven and transfer it to a cooling rack or a serving board. Finish with a light drizzle EVOO and sprinkle of dried oregano, if desired. Allow to cool slightly before slicing.Now it’s time to enjoy your Focaccia with Onion and Nduja!
