Quick-Pickled Zucchini and Summer Squash

Zucchini plants are famous for going from "a few" to "more than anyone can eat" within a week. Pickling doesn't require the zucchini to be perfectly fresh either - slightly overgrown squash that's gone a bit spongy in the center still pickles well once sliced thin, since the brine firms up the texture again.

What You'll Need

• 1 lb zucchini or yellow summer squash, sliced into thin rounds or ribbons
• 1 cup apple cider vinegar (its slight sweetness suits squash better than plain white vinegar)
• 1 cup water
• 1 tbsp kosher salt
• 1 1/2 tbsp sugar
• 1/2 tsp red pepper flakes (optional)
• 1 small shallot or 1/4 red onion, thinly sliced
• A few sprigs fresh dill or oregano

Method

Slice the zucchini thin - a mandoline makes this fast and even, but a sharp knife works fine. Toss the slices with 1 tsp of salt and let them sit in a colander for 15 minutes to draw out excess water; this step keeps the pickle from turning watery in the jar. Pat dry.

Pack the zucchini, shallot, and herbs into a jar. Heat the vinegar, water, salt, and sugar until dissolved, pour over the zucchini while still warm, and let cool before sealing and refrigerating.

Thin slices are ready in about 2 hours. They keep for roughly 10 days refrigerated - zucchini has more water content than cucumber, so it doesn't hold its texture quite as long. Full detail on storage windows across vegetables is in how long quick pickles last.

Why This Works Even on Overgrown Zucchini

A zucchini left on the vine too long develops a spongier texture and larger seeds, which is usually a problem for cooking but less of one for pickling - thin slicing minimizes the spongy part, and the acid in the brine tightens the flesh back up. It's a good use for the baseball-bat-sized zucchini that always seems to hide under the leaves until it's too big for most other recipes.

What to Do With Them

Pickled zucchini works anywhere a cucumber pickle would - on sandwiches, chopped into a grain bowl, or served alongside a grilled zucchini and pepper salad for a contrast between the fresh and the pickled versions of the same vegetable. It also holds up well as a topping on richer dishes like a baked zucchini and tomato sauce dish, where the acidity balances the cheese.

If the zucchini surplus is bigger than what pickling alone can handle, rotate in fresh preparations too - sauteed zucchini ribbons and zucchini pasta both use a similar volume per batch and take under 15 minutes.
