Double Onion Barbecue Sheet Pan Pizza

This unfussy double-onion barbecue chicken pizza has a luscious layer of barbecue sauce and two layers of onions. Sweet, caramelized onions and a topping of thinly sliced red onions that get roasted over the mixture of gouda and mozzarella as the pizza bakes. Make it for game night or a weekend party; either way, it’s a crowd-pleaser.

  • Yield: 4


1 lb/455 g white or yellow onion, halved and thinly sliced

2 Tbsp extra-virgin olive oil

Fine sea salt

½ lb/230 g pizza dough, homemade or store-bought

1 Tbsp coarsely ground cornmeal or semolina

½ cup/120 ml barbecue sauce plus extra to serve, homemade or store-bought

1 cup/200 g diced or shredded grilled or rotisserie chicken

½ cup/50 g shredded gouda

½ cup/40 g shredded mozzarella

½ cup/50 g red onion, halved and thinly sliced

1 tsp nigella seeds

2 scallions, both white and green parts, ends trimmed and discarded, thinly sliced


  1. Preheat the oven to 350F/180C.
  2. Mix the onions with 1 Tbsp of oil and a tiny pinch of salt on a baking sheet. Wrap the sheet tightly with a layer of foil, crimping the edges to seal. Place in the oven and cook for 30 minutes, remove from the oven, and unwrap. The onions will be slightly tender and shrink slightly, move them in a clump towards the center, return the baking sheet to the oven, and roast uncovered for an additional 30 minutes, occasionally stirring with a spatula until the onions turn golden brown and soft. The cooking time might vary. Remove the baking sheet from the oven and keep aside. This should yield about 1 cup of caramelized onions.
  3. When ready to cook the pizza, preheat the oven to 500F/260C.
  4. Brush the surface of a 9 in by 12 in/23 cm by 30.5 cm baking sheet with 1 Tbsp of oil. Sprinkle the cornmeal all over the surface. Roll out the pizza dough and spread it using your fingers to cover the baking sheet’s surface. Cover with a damp towel and let rest for 30 minutes in a warm spot in the kitchen, away from sunlight. The dough will relax and rise a little.
  5. Brush the surface of the pizza with the barbecue sauce followed by the caramelized onions. Top with the chicken, gouda, mozzarella, and red onion. Sprinkle the nigella seeds on the top and bake the pizza in the oven until the edges start to brown and the cheese melts and turns brown in some spots, 10 to 12 minutes. Rotate the baking sheet and bake for 4 to 5 minutes until the crust is crisp and turns a dark shade of golden brown. Remove from the oven, transfer to a cutting board, sprinkle the sliced scallions over the top, and serve immediately with extra barbecue sauce on the side. Leftovers can be stored wrapped in foil or cling film in the refrigerator for up to 4 days. Preheat leftovers in an oven at 350F/180C.


  • I prefer making caramelized onions in the oven over the stove. The heating is more uniform in an oven, and I find it takes less time than on a stove which can be very unpredictable. The onions are first steamed covered in the method shared to help soften them. In the second step, the onions are cooked in a clump in the center of the baking sheet; this prevents them from drying out and turning crisp, making the result jammy. I will spread them in a single layer over the baking sheet if I want them crispy.
  • For a thicker crust, use 1 lb/455 g pizza dough.
  • You can also use cilantro with or without scallions for the garnish.
