This caramelized onion and Brussels sprout pizza is a delicious idea for a winter pizza topping! Make it a heart shaped pizza for someone you love.




  1. Make the pizza dough: Follow the Best Pizza Dough recipe to prepare the dough. (This takes about 15 minutes to make and 45 minutes to rest.)
  2. Make the caramelized onions: Peel, halve, and slice the onions as thinly as possible. In a very large skillet, heat 2 tablespoons olive oil over medium high heat. Add the onions, which can mound in the skillet if necessary. Saute, stirring frequently, about 10 minutes until soft and translucent. Add 1 teaspoon kosher salt and reduce the heat to medium-low, finding a temperature that is not so hot that the onions burn but not so low that they do not continue to cook. Cook slowly, stirring every 5 to 10 minutes or so, until very reduced and dark brown, about 40 minutes. The onions will turn from translucent white to golden to brown to a rich, caramely dark brown color, and the volume will have reduced by at least 4 times.
  3. Place a pizza stone in the oven and preheat to 500°F. OR preheat your pizza oven (here’s the pizza oven we use).
  4. Make the Easy Pizza SauceThinly slice the Brussels sprouts.
  5. When the oven is ready, dust a pizza peel with cornmeal or semolina flour. (If you don’t have a pizza peel, you can use a rimless baking sheet or the back of a rimmed baking sheet. But a pizza peel is well worth the investment!) Stretch the dough into a circle; see this video for instructions. Then gently place the dough onto the pizza peel. Cut a small divot into the top of the circle, then form the bottom of the dough into a point so that it forms a heart shape. (Note: Since the heart-shaped pizza is a bit more fragile than other shapes, it’s easiest to use a conveyor-type pizza peel to slide it into the oven if you can. If not, cross your fingers and slide quickly!)
  6. Spread the sauce in a thin layer across the dough. Top with mozzarella cheese and shavings of Pecorino cheese (use a vegetable peeler). Add dollops of caramelized onions, then sprinkle all over with Brussels sprouts and a few pinches kosher salt.
  7. Transfer the pizza to the pizza stone on the pizza peel, then bake until the cheese is melted, about 7 minutes.
