Ingredients
This recipe uses a simple, flavorful combination of vinegar, garlic, herbs, and spices to transform fresh Brussels sprouts into a bold, crunchy pickle. Here’s what you’ll need:
- 1½ lbs fresh Brussels sprouts, trimmed and halved
- 1½ cups white vinegar
- 1½ cups water
- 2 tbsp granulated sugar
- 1 tbsp kosher salt
- 4 garlic cloves, thinly sliced
- 1 tsp black peppercorns
- 1 tsp mustard seeds
- 1 tsp red pepper flakes
- 2 bay leaves
- 2 tbsp fresh dill, chopped
Instructions
Making pickled Brussels sprouts at home involves a few key stages: blanching, building the brine, and letting the flavors develop in the fridge.
Wash the Brussels sprouts thoroughly, trim the stems, and remove any damaged or yellowing outer leaves. Cut any larger sprouts in half so they pickle evenly and are easier to eat; smaller sprouts can be left whole if desired.
Bring a large pot of water to a boil. Blanch the Brussels sprouts for 2 to 3 minutes, just until they turn bright green and slightly tender on the outside. Immediately transfer them to a bowl of ice water to stop the cooking process. This blanch-and-shock method is essential for pickled Brussels sprouts — it softens the sprouts just enough to allow the brine to penetrate while locking in that satisfying crisp-tender crunch. Once cooled, drain the sprouts thoroughly.
In a saucepan, combine the white vinegar, water, granulated sugar, kosher salt, black peppercorns, mustard seeds, red pepper flakes, and bay leaves. Bring the mixture to a gentle boil, stirring occasionally until the sugar and salt fully dissolve.
While the brine comes together, place the thinly sliced garlic and chopped fresh dill into a clean glass jar. Layering the aromatics at the bottom of the jar helps their flavor infuse evenly throughout the sprouts as the brine is poured in.
Pack the blanched, drained Brussels sprouts tightly into the jar on top of the garlic and dill. Packing them snugly helps ensure the jar holds enough brine to fully submerge the sprouts.
Pour the hot pickling brine over the Brussels sprouts until they are completely submerged. Full submersion is essential for even pickling and helps prevent spoilage.
Let the jar cool to room temperature on the counter before sealing and refrigerating. This helps prevent thermal shock and ensures safe, gradual cooling.
Seal the jar tightly with a lid and transfer it to the refrigerator.
Allow the Brussels sprouts to pickle for at least 48 hours before serving. This resting period is essential for both flavor and texture — the sprouts need time to fully absorb the tangy, garlicky, spicy brine, and the extended chill time helps achieve that perfect crisp, tangy bite. Many people find the flavor continues to improve through the first week.
