Brussels Sprouts Pizza with Balsamic Red Onions from Cookie + Kate
Showing 3 out of 6 Steps
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. 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.
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. Drizzle the sprouts with 1½ teaspoons olive oil and toss well. Rub the oil into the sprout leaves so they're all lightly coated in oil, adding another dash of oil if necessary. Toss with a sprinkle of salt and pepper and set aside.
Preheat oven to 425 degrees Fahrenheit and place a pizza stone on the middle rack if you have one. Slice your onions into thin rounds (the thinner you slice them, the faster they will cook).
