Zucchini Bread and Butter Pickles: A Taste of Summer Preserved

There’s a certain magic that happens in my kitchen when zucchini season hits its peak. Mountains of glossy green orbs arrive from the garden, and while I adore a good zucchini gratin or a slice of moist zucchini bread, my true passion lies in preserving that vibrant, garden-fresh flavor. For years, my grandmother’s recipe for zucchini bread and butter pickles has been a treasured artifact, its handwritten notes smudged with years of use. The aroma of simmering vinegar, sweet sugar, and earthy spices, mingling with the fresh scent of zucchini, instantly transports me back to her sun-drenched kitchen, a place where summer’s bounty was meticulously transformed into jars of pure delight to be savored all year long.

Ingredients

The beauty of these pickles lies in their simplicity, allowing the fresh flavors of the zucchini to shine through.

• 8 cups zucchini, sliced thinly (about 1/8 inch thick)
• 1 large onion, thinly sliced (optional, but I find it adds a delightful depth)
• 3 tablespoons salt (kosher or sea salt work best)
• 3 cups white vinegar
• 1 ½ cups sugar
• 2 tablespoons celery seeds
• 4 tablespoons mustard seeds
• 1 tablespoon turmeric

Equipment Needed

To embark on this pickling adventure, you’ll want to have the following on hand:

• A large colander or sieve
• A large bowl
• A large, heavy-bottomed pot or Dutch oven
• Sterilized canning jars with lids and bands
• Tongs (for handling jars and lids)
• A large pot for the water-bath canning process
• A clean dishtowel

Instructions

Preserving these pickles is a rewarding process that yields a delightful treat. Follow these steps carefully to ensure success.

1. Prepare the Zucchini and Onion: Begin by placing a large colander or sieve over a large bowl. Add your thinly sliced zucchini and onion (if using) to the colander. Sprinkle the salt evenly over the vegetables and toss them gently with your hands to ensure they are well coated. Allow this mixture to sit for at least 30 minutes. This crucial step draws out excess moisture from the zucchini and onion, which is essential for achieving the perfect pickle texture.

2. Rinse and Dry: After the 30-minute resting period, rinse the zucchini and onion thoroughly under cold running water. This removes the salt. Once rinsed, spread the vegetables out on a clean dishtowel and pat them dry as much as possible. The drier they are, the better they will absorb the pickling brine.

3. Prepare Jars for Canning: While the vegetables are draining, it’s time to sterilize your jars. Wash your canning jars thoroughly with dish soap and rinse them well. Place the jars upright in a large pot, ensuring they are completely covered by at least 1 to 2 inches of water. Bring the water to a boil, then reduce the heat to a low simmer and keep the jars covered and simmering for at least 10 minutes. Leave the jars in the simmering water until you are ready to fill them.

4. Prepare Lids and Bands: Wash and rinse the flat canning lids and the round screw-on bands separately. Set the bands aside. Place the flat lids in a small pan and cover them with boiling water. Let them simmer for 5 minutes, then leave the lids resting in the hot water until needed.

5. Make the Pickling Brine: In a large, heavy-bottomed pot on the stovetop, combine the white vinegar, sugar, celery seeds, mustard seeds, and turmeric. Turn the heat to medium-high and stir continuously until the sugar is completely dissolved and the mixture comes to a boil. This aromatic brine is the heart of your pickles.

6. Cook the Zucchini and Onions: Add the rinsed and dried zucchini and onion slices to the boiling brine. Stir gently to combine. Cook for precisely 10 minutes, stirring occasionally. During this time, the zucchini and onions will become limp and tender, absorbing the delicious flavors of the brine.

7. Fill and Seal the Jars: Carefully remove the hot jars from the simmering water using tongs. Do not discard the hot water from the canning pot; it will be used for the water-bath processing. Ladle the hot pickles into the hot jars, ensuring you leave a ½-inch headspace at the top of each jar. This headspace is important for proper sealing.

8. Add Lids and Bands: Take the clean lids from their sterilizing water and place them on the jars, rubber side down. Screw the bands onto the lids until they are hand-tight.

9. Water-Bath Processing: Using tongs, carefully lower the filled and sealed jars into the hot water in the canning pot. Ensure the jars are completely submerged. Bring the water back to a rolling boil. Once boiling, process the jars in the boiling water bath for exactly 10 minutes. This step is crucial for safely preserving the pickles.

10. Cool and Check Seals: Remove the jars from the boiling water bath and place them on a countertop or a cooling rack. As the jars cool, you will likely hear a satisfying “pop” sound from each one. This indicates that the lids are sealing properly. Once completely cool, check the seals by pressing down on the center of each lid. A properly sealed lid will be rigid and will not flex when you push on it. If a lid does not seal, refrigerate the jar and consume the pickles within a few weeks.

Expert Tips & Tricks

• Uniform Slicing is Key: For the most consistent texture and flavor absorption, try to slice your zucchini and onion as uniformly as possible. A mandoline slicer can be a helpful tool here, but a sharp knife and a steady hand will also do the trick.
• Don’t Skip the Draining: That initial salting and draining step might seem tedious, but it’s vital. Removing excess water prevents your pickles from becoming mushy and ensures they have that delightful crisp-tender texture.
• Sterilization is Non-Negotiable: Proper sterilization of jars and lids is paramount for safe canning. Always follow these steps diligently to prevent spoilage and potential health risks.
• Headspace Matters: That ½-inch headspace is not just a suggestion; it’s a critical component of a successful seal. Too little, and the food might expand and push the lid off; too much, and the lid might not seal properly.

Serving & Storage Suggestions

These Zucchini Bread and Butter Pickles are incredibly versatile. Their sweet and tangy profile makes them a fantastic accompaniment to a wide array of dishes.

Serve them alongside grilled burgers, pulled pork sandwiches, or fried chicken for a bright, acidic counterpoint. They’re also delightful as part of a charcuterie board, adding a unique crunch and flavor to your spread. Don’t underestimate their charm as a simple, refreshing side dish for any summer meal.

Properly sealed, these pickles can be stored in a cool, dark pantry for up to a year. Once opened, they should be refrigerated and will maintain their best quality for about 3-4 weeks.

• Herbal Infusion: Tuck a sprig of fresh dill or a few mustard seeds into each jar before sealing for an added layer of aromatic complexity.
• Different Vinegars: While white vinegar is traditional, you could experiment with apple cider vinegar for a fruitier note, though it will slightly alter the color and flavor profile.

FAQs (Frequently Asked Questions)

Q: Why do I need to salt and drain the zucchini?
A: Salting and draining removes excess water from the zucchini, which prevents the pickles from becoming soggy and ensures a better texture.

Q: Can I use a different type of vinegar?
A: White vinegar is recommended for its clean, sharp flavor. Other vinegars like apple cider vinegar can be used, but they will change the final taste and color of the pickles.

Q: How do I know if my jars have sealed properly?
A: A properly sealed lid will be concave (curved inward) and will not flex when pressed in the center. You will also likely hear a distinct “pop” as the jars cool.

Q: What happens if a jar doesn’t seal?
A: If a jar does not seal, refrigerate it immediately and consume the pickles within a few weeks. Unsealed jars are not safe for long-term shelf storage.

Q: Can I make these pickles without onions?
A: Absolutely! The onion is optional. If you prefer a purely zucchini pickle, simply omit the onion from the recipe.
