Brussels Sprouts Pizza


Balsamic red onions

  • 1 to 2 tablespoons olive oil
  • 2 medium or 1 extra-large red onion
  • Pinch red pepper flakes
  • Dash salt
  • ¼ cup balsamic vinegar

Brussels sprouts

  • 8 ounces (½ pound) Brussels sprouts
  • 1 ½ to 2 teaspoons olive oil
  • Salt and freshly ground black pepper

Pizza Toppings

  • 1 ½ to 2 cups grated low-moisture part-skim mozzarella cheese (6 to 8 ounces), depending on how cheesy you like your pizza
  • ¼ cup grated Parmesan cheese


  1. Preheat oven to 425 degrees Fahrenheit and place a pizza stone on the middle rack if you have one.
  2. Slice your onions thinly.
  3. Prepare the Brussels by slicing off the tough ends and discarding them. Use your fingers to pull off the individual leaves around the outside, then trim off the newly exposed tough end, and continue until you have broken the sprout into leaves. Repeat for about half of the Brussels sprouts, then slice the rest into thin slices from top to bottom.
  4. Drizzle the Brussels sprouts with 1 ½ teaspoons olive oil and toss well with a sprinkle of salt and pepper. Set aside.
  5. To prepare the red onions, warm 1 tablespoon olive oil in a large skillet over medium heat. Add the onions, a pinch of red pepper flakes and a dash of salt. Toss to combine. Cover and cook, stirring occasionally, for 10 minutes, or until the onions are nice and soft. The thinner you sliced them, the sooner they will cook.
  6. Pour in the balsamic vinegar and stir to combine. Continue cooking, uncovered, for a few more minutes, until the balsamic vinegar has condensed and mostly absorbed into the onions. Remove from heat and set aside to cool.
  7. Prepare the pizza dough as directed. If you’re using the Heirloom Family Kitchen pizza dough recipe, you'll have enough dough to make two pizzas. For best results, roll the dough out as thin as reasonably possible while maintaining an even surface level.
  8. Top the dough with an even layer of red onions, followed by mozzarella cheese. Sprinkle the Brussels on top, then finish with a sprinkling of Parmesan cheese.
  9. Transfer one pizza to the oven at a time (if you don’t have a baking stone, bake your pizza on a cookie sheet). Bake until the crust is golden, the cheese is bubbly and the Brussels sprouts are crispy on the edges, about 10 to 14 minutes.
