This delicious vegetarian pizza with brussels sprouts, caramelized onion and hot honey is a fun new recipe to try for pizza night!


  • 1 pizza dough or crust
  • 1 tbsp + 1 tsp olive oil, divided
  • 1 small red onion, thinly sliced
  • 1 tsp balsamic vinegar
  • 1 cup brussels sprouts
  • Salt
  • Pepper
  • 2/3 cup mozzarella cheese
  • 1-2 tsp hot honey (optional, recipe follows)

For hot honey:

  • 1/4 cup honey
  • 1/4 tsp chili flakes


  1. Place a pizza stone in the oven to preheat. Heat oven to 500°F.
  2. Heat 1 tbsp of the oil in a small skillet. Add sliced onion and cook over low heat, stirring, until onions are caramelized, about 10-15 minutes. Add vinegar to onions and stir to coat. Remove onions from the skillet and set aside.
  3. Trim woody ends from brussels sprouts and slice from top to bottom. Add remaining 1 tsp oil to the skillet and cook brussels sprouts over medium heat for about 5 minutes. Season with salt and pepper.
  4. Build the pizza. Stretch or roll pizza dough into a circle on a piece of parchment paper.
  5. Spread caramelized onions evenly over the dough. Top with half of the mozzarella, then the brussels sprouts, then the remaining mozzarella.
  6. Carefully slice the parchment onto the preheated pizza stone and bake pizza for 8-10 minutes, or until cheese is bubbly and crust is golden.
  7. Remove pizza from the oven and drizzle with hot honey just before serving.

To make the hot honey:

  1. Add honey and chili flakes to a small saucepan.
  2. Heat over low heat until just barely simmering, then remove from heat.
  3. Store honey in an airtight container at room temperature.


  • If you don't have a pizza stone, you can use a baking sheet.
  • I like to use fresh whole milk mozzarella (sold in a ball), but shredded mozzarella also works.
  • I like to use my whole wheat pizza dough or sourdough pizza dough recipe for the crust. You can also use a pre-made crust if you like.
