These homemade cornichons are crisp, tangy, and full of bold flavor.

Why You’ll Love This Recipe
Cornichons are easy to make and require only a handful of ingredients, yet they bring a complex flavor that feels refined and special. Their sharp, tangy taste cuts through rich dishes like cheese or sandwiches, making them the perfect companion for heavier foods. Unlike sweet pickles, these are purely sour and savory, which makes them ideal for those who prefer bold flavors. You’ll also appreciate how customizable they are—you can adjust the herbs and spices to suit your taste. Plus, making them at home allows you to control the salt level and avoid unnecessary additives.
Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
500 g small cucumbers (very young and firm)
500 ml white vinegar
250 ml water
1 tablespoon salt
2 cloves garlic, peeled
1 teaspoon mustard seeds
1 teaspoon black peppercorns
1 small bunch fresh dill or 1 teaspoon dried dill
1 teaspoon dried tarragon (optional)
1 small onion, sliced thinly
Directions
Start by washing the small cucumbers thoroughly and trimming off any stems. Place them in a bowl, sprinkle with salt, and let them sit for about 2 hours. This step helps draw out excess moisture and keeps the pickles crisp.
After resting, rinse the cucumbers under cold water and pat them dry with a clean towel.
In a saucepan, combine the vinegar and water. Bring the mixture to a gentle boil, then remove it from heat.
In a clean glass jar, place the garlic cloves, mustard seeds, peppercorns, dill, tarragon, and sliced onion. Pack the cucumbers tightly into the jar.
Pour the warm vinegar mixture over the cucumbers until they are fully submerged. Make sure there are no air pockets.
Seal the jar tightly and allow it to cool to room temperature. Once cooled, place it in the refrigerator.
Let the cornichons sit for at least 3 days before eating, though they taste even better after a week as the flavors fully develop.

Variations
You can easily adapt this recipe to create different flavor profiles. Add a pinch of chili flakes if you enjoy a bit of heat. For a more aromatic version, include coriander seeds or bay leaves. If you prefer a slightly milder acidity, replace a small portion of the vinegar with additional water. You can also experiment with herbs like thyme or rosemary for a more Mediterranean twist. While traditional cornichons are not sweet, adding a small pinch of sugar can soften the sharpness if desired.
Storage/Reheating
Cornichons should always be stored in the refrigerator in a sealed jar. They can last up to 3 to 4 weeks when properly stored in their brine. Always ensure the cucumbers remain fully submerged to maintain freshness and prevent spoilage.
These pickles are not meant to be reheated. They are best enjoyed cold or at room temperature as a crunchy, tangy accompaniment.
