This Giardiniera lets you bring authentic Italian deli flavor home with crisp vegetables and a tangy brine that brightens any meal. Made with fresh cauliflower, peppers, and olives, it’s ready after a quick simmer and overnight rest. You’ll love keeping this versatile condiment on hand for antipasto platters, sandwiches, or as a zesty snack straight from the jar.

I first fell for giardiniera during a summer in Chicago, where it crowned every Italian beef sandwich with glorious crunch and heat. That memory inspired me to create my own homemade version, which now graces our charcuterie boards and picnic baskets year round. I particularly love pairing its vibrant acidity with creamy dishes like my labneh burrata appetizer or serving it alongside crusty bread dipped in garlic infused olive oil. It transforms simple meals into something special.

Ingredients

Vegetables

1 cup small cauliflower florets
3/4 cup carrot, cut into 1/4-inch thick coins
3/4 cup celery, cut into 1/4-inch thick slices
3/4 cup red bell pepper, seeded and cut into 1-inch pieces
1/2 cup serrano peppers, thinly sliced or jalapeño peppers
1/2 cup green olives, pitted

Brine

1/2 cup red wine vinegar
1/3 cup pure olive oil
2 tablespoons granulated sugar
4 cloves garlic, minced
2 teaspoons dried oregano
1 teaspoon kosher salt
1/2 teaspoon black pepper, freshly ground

Instructions

Combine the cauliflower florets, carrot coins, celery slices, bell pepper pieces, sliced serrano peppers, and pitted green olives in a large heatproof bowl.
In a medium saucepan, combine the red wine vinegar, pure olive oil, sugar, minced garlic, dried oregano, salt, and black pepper. Bring the mixture to a simmer over medium-high heat, stirring until the sugar dissolves completely.
Carefully pour the hot vinegar brine over the vegetables and olives in the bowl. Stir the mixture thoroughly to ensure all the vegetables are evenly coated in the brine.
Allow the mixture to cool at room temperature for about 1 hour, stirring occasionally. Then, cover the bowl tightly with plastic wrap and refrigerate for at least 24 hours, and up to 5 days, to let the flavors meld and the vegetables crisp-tender.
Before serving, give the giardiniera a good stir. Use a slotted spoon to transfer the pickled vegetables and olives to a serving bowl, leaving the excess brine behind. Serve chilled or at room temperature.

Notes

Let giardiniera rest at least 24 hours for best flavor. Store in refrigerator for up to 5 days.

Frequently Asked Questions

How long does homemade giardiniera last?

Properly stored in airtight containers in the refrigerator, homemade giardiniera stays crisp and flavorful for up to 3 weeks. The vegetables may soften slightly after the first week but maintain their delicious taste. Always use clean utensils when serving to prevent contamination.

Can I use different vegetables in giardiniera?

Yes, giardiniera is wonderfully adaptable. Try adding pearl onions, green beans, or cherry tomatoes for variety. Firmer vegetables work best as they maintain texture during pickling. Adjust cutting sizes to ensure even absorption of the flavorful brine.

Is giardiniera served hot or cold?

Giardiniera is typically served chilled or at room temperature. Heating can soften the vegetables too much and alter the bright, tangy flavors. For best results, remove from refrigerator 15 minutes before serving to take the chill off.

What’s the difference between giardiniera and relish?

Giardiniera features larger, distinct vegetable pieces in an oil and vinegar brine, while relish is finely chopped and typically has a sweeter, more uniform texture. Giardiniera maintains the individual character of each vegetable, offering varied textures and flavors in each bite.
