Wash the zucchini and trim off the ends. Cut into 1/4-inch chips or sturdy spears, discarding any large seedy centers from oversized zucchini.

Divide the dill, garlic, mustard seeds, peppercorns, dill seed, and red pepper flakes between three clean pint jars.
03 -
Add the zucchini to the jars, packing it snugly but not crushing it. Leave about 1/2 inch of space at the top.
04 -
Combine vinegar, water, salt, and sugar in a small saucepan. Bring to a simmer over medium heat and stir until the salt and sugar dissolve, about 3-5 minutes.
05 -
Carefully pour the hot brine over the zucchini until fully covered. Tap the jars gently to release air bubbles, then add more brine if needed.

Let the jars cool at room temperature for about 30 minutes. Cover and refrigerate for at least 24 hours, or 48 hours for a stronger flavor.
