Equipment

  • half sheet pan
  • immersion blender

Ingredients

  • 3 tablespoons (45 milliliters) balsamic vinegar
  • 1 tablespoon (15 milliliters) olive oil
  • 2 large cloves garlic peeled and rough chopped
  • 2 stems fresh rosemary leaves about 1 heaping tablespoon or 10 grams
  • 1/2 tablespoon (10 grams) Dijon mustard
  • 1 teaspoon (6 grams) kosher salt
  • 1/4 teaspoon black pepper
  • 2 pounds (710 grams) Brussels sprouts trimmed, rinsed and dried well, and sliced in halves lengthwise

Instructions

  • Heat an oven to 425°F (220°C).

Prepare the Balsamic Vinaigrette

  • Add the balsamic vinegar, olive oil, garlic, rosemary, Dijon mustard, kosher salt, and black pepper to a pint-sized mason jar.
    Use an immersion blender, set to medium speed, to blend these ingredients together for 60-90 seconds. 

Dress the Brussels Sprouts

  • Add the Brussels sprouts to a large mixing bowl.
    Pour the balsamic vinaigrette over the Brussels sprouts and use your hands to toss them in the vinaigrette ensuring each sprout is coated in the vinaigrette. 
  • Arrange the balsamic Brussels on a bare sheet pan in a single layer with the cut side facing down.
    Avoid crowding them too much on the pan.

Roast the Brussels Sprouts

  • Roast Brussels sprouts in a 425°F (220°C) oven for 20-25 minutes or until charred.
  • Allow the roasted Brussels sprouts to cool on the pan for 1 minute before removing them with a spatula. 
    Serve roasted balsamic Brussels sprouts as a side dish with baked, grilled, or fried proteins.

Notes

Swaps and Substitutions:
  • Replace the balsamic vinegar with soy sauce (for an Asian flair), white balsamic vinegar, or red or white wine vinegar.
  • You can replace the balsamic vinegar with lemon juice or malt vinegar, but you'll need to add 1 tablespoon (20 grams) of honey or sugar to offset the acidity.
  • Replace the fresh rosemary with 1 teaspoon (1g) dried crushed rosemary.
  • Swap the Dijon mustard for prepared yellow mustard or whole grain, spicy mustard. 
Tips and Techniques:
  • When shopping for Brussels sprouts, choose firm, tight buds that are 3/4- 1 1/2 inches (2-4cm) in size with bright green and blemish-free leaves. 
  • I recommend making the balsamic vinaigrette with an immersion blender because there's not enough liquid to blend it in a traditional blender.
  • Make this balsamic vinaigrette a week before using it and store it in an airtight container or jar in the fridge for up to one week.
  • Double the balsamic vinaigrette if you prefer more balsamic and less Brussels sprouts flavor or to use it as a marinade or salad dressing.
  • It isn't necessary to grease the pan because the balsamic vinaigrette contains oil, but you can lightly grease the pan if you feel more comfortable doing so.
  • Arranging the Brussels cut side down guarantees a perfectly caramelized sprout after roasting.
  • Roasted Brussels sprouts also make a great appetizer.
Storage Instructions:
  • Store leftover roasted Brussels sprouts in an airtight container in the fridge for 4 days. 
  • To reheat Brussels sprouts, microwave them for 1 1/2-2 minutes on medium power. You can also reheat them in a 200°F (90°C) oven for 10 minutes. 
Freezing Instructions:
This method of freezing Brussels allows you to heat up the desired amount of Brussels instead of a whole batch.
  1. Allow the Brussels to cool completely on the pan, then put the pan in the freezer to freeze them until solid.
  2. Once the Brussels sprouts are frozen, remove them from the pan using a spatula and transfer them to a freezer-safe bag for up to 2 months.
  3. Remove the amount of Brussels you want to reheat, thaw them overnight, and reheat them following the instructions above.
