Ingredients

For the pickled red onions:

  • 1 small red onion quartered and sliced thinly
  • 1 tablespoon sugar
  • 1 tablespoon kosher salt
  • 1/2 teaspoon peppercorns
  • 1 cup white vinegar
  • approximately 1 cup boiling water

For the brussels sprouts:

  • 1 lb. brussels sprouts washed, trimmed, and halved (or quartered, if large)
  • 2 tablespoons extra-virgin olive oil
  • salt and pepper to taste

Instructions

  • To make the pickled red onions, fill a mason jar with the sliced onions. Add the sugar (1 tablespoon), salt (1 tablespoon), peppercorns (1/2 teaspoon), and vinegar (1 cup) to the jar. Add boiling water to the jar, cover, and shake. Refrigerate for at least 30 minutes; overnight for best flavor.
  • To roast the brussels sprouts, mix the sprouts in a bowl with the olive oil (2 tablespoons), salt, and pepper. Spread in an even layer on a parchment covered baking sheet and roast in a 425 degree oven for approximately 30 minutes, or until tender and well roasted, stirring/flipping over every 10 minutes or so.
  • Serve the pickled onions on top of the brussels sprouts. Use leftover onions for sandwiches or salads!

Notes

  • To save on time, make the pickled onions beforehand. They will last for months in the fridge.
