Best Substitutes for Capers
Capers are salt-cured flower buds that pack an intense punch of salty, tangy, slightly bitter flavor with a firm pop when you bite them. They measure about 4-8mm across for standard size, with smaller ones (nonpareils at 3-4mm) being more prized for their delicate texture. The brining process creates their signature sharp, vinegary bite that cuts through rich dishes like butter, cream sauces, and fatty meats. When substituting, you need something that delivers both the acidic brightness and the textural contrast. Most alternatives won't replicate the exact floral notes, but they can provide the essential flavor function capers serve in a dish.
Best Overall Substitute
Chopped green olives at a 1:1 ratio. They match the briny, salty intensity and provide similar bursts of flavor when bitten. Castelvetrano or Cerignola olives work best because they're less bitter than Kalamata. Chop them to match caper size, about 3-4mm pieces.
All Substitutes
Green olives, chopped
1:1 by volumeGreen olives deliver the same briny punch and firm texture as capers. Castelvetrano olives are mildest, while Cerignola adds more salt. Chop into 3-4mm pieces to match caper size. The olive flavor is earthier than capers' floral notes, but the salt and acid levels are nearly identical. Works in both cooked dishes and raw applications like salads or tapenade.
Green peppercorns (brined)
3/4 the amount called forBrined green peppercorns provide the closest match to capers' texture and briny bite. They're about the same size (4-6mm) and pop when bitten. The flavor is more peppery than salty, with less acidity, so use 25% less and add a pinch of white wine vinegar to compensate. Available in specialty stores or online, usually in small jars near the pickles.
Cornichons, diced
1:1 by volumeThese tiny French pickles (15-20mm long) deliver sharp acidity and crunch when diced to 3-4mm pieces. They're more sour than salty compared to capers, with a crisp snap rather than a soft pop. The vinegar brine matches capers' tanginess perfectly. Best in dishes where the pickle flavor won't clash, like potato dishes or rich meats.
Diced pickled onions
1:1 by volumeQuick-pickled pearl onions or cocktail onions, diced to 3-4mm, provide acidic bite and crunch. They're sweeter than capers but the vinegar brine adds the necessary tang. The onion flavor is mild when pickled and works well in Mediterranean dishes. Make sure to drain them well to avoid adding excess liquid to your dish.
Pickled jalapeño, minced
1/2 the amount called forPickled jalapeños bring heat along with the acidic bite, so use half the amount. Remove seeds and mince to 2-3mm pieces. The vinegar brine provides the tangy element capers deliver, while the pepper adds complexity. Works best in dishes that can handle some spice. The texture is softer than capers but still provides contrast.
Preserved lemon peel, minced
1/2 the amount called forThe salt-cured peel of preserved lemons delivers intense saltiness and citrus brightness. Rinse off excess salt, remove any remaining pulp, and mince the peel to 2-3mm pieces. Use half the amount because the flavor is more concentrated. The texture is slightly chewy rather than crisp, but the flavor impact is similar to capers.
Anchovy paste mixed with lemon juice
1/4 tsp paste + 1/4 tsp lemon juice per 1 tsp capersThis creates the umami depth and saltiness capers provide, plus acid from the lemon. Mix 1/4 teaspoon anchovy paste with 1/4 teaspoon fresh lemon juice to replace 1 teaspoon capers. The texture is smooth rather than textural, so this works best in sauces and dressings where capers would be mashed anyway.
Diced dill pickle
3/4 the amount called forKosher dill pickles, diced to 3-4mm pieces, provide acidic punch and crunch. Use 25% less because pickles can be more sour than capers. The dill flavor adds an herbal note that works well in egg dishes and potato salads. Drain excess liquid to avoid making your dish too wet.
White wine vinegar with salt
1/4 tsp vinegar + pinch of salt per 1 tsp capersWhen you need the flavor but not the texture, mix 1/4 teaspoon white wine vinegar with a pinch of coarse salt per teaspoon of capers called for. This provides the acidic bite and saltiness without any textural element. Best for dishes where capers would be chopped fine anyway, like in sauces or dressings.
How to Adjust Your Recipe
When subbing capers in cream sauces, add the substitute at the end of cooking to prevent curdling from excess acid. For dishes like chicken piccata, taste as you go since substitutes vary in salt content. If your substitute is less salty than capers (like cornichons), add a pinch of sea salt. More acidic subs like pickled jalapeños may require backing off other acidic ingredients by 25%. In cold preparations like pasta salad, let the dish sit 15-20 minutes before serving so flavors meld properly.
When Not to Substitute
Skip substitutions in traditional caper-forward dishes like puttanesca sauce or vitello tonnato where capers are a defining flavor. High-end restaurants often feature caper berries (the fruit of the caper plant) as garnish, and nothing replicates their unique appearance and mild flavor. Fried capers, which become crispy and nutty, can't be substituted since the cooking method turns their character completely. Caper-stuffed olives obviously need real capers to work.
Frequently Asked Questions
Can I use caper berries instead of regular capers?
Use 1 caper berry for every 3-4 regular capers. Caper berries are the fruit of the caper plant, about 15-20mm long with stems attached. They're milder and less salty than cured capers, with a grape-like texture. Remove stems before using and expect a gentler flavor that won't provide the same punch as regular capers.
How much salt should I add when using green olives as a substitute?
Start with no additional salt since green olives are already brined. Taste after adding them to your dish. If you need more saltiness to match capers' intensity, add 1/8 teaspoon kosher salt per 2 tablespoons of chopped olives. Castelvetrano olives are less salty than Cerignola, so they might need a pinch more salt.
What's the best caper substitute for someone avoiding salt?
Use 1/2 the amount of minced fresh herbs like tarragon or dill mixed with 1/4 teaspoon lemon zest per tablespoon of capers called for. This won't replicate the briny flavor but provides brightness and complexity. Fresh herbs add around 5-10mg sodium per tablespoon versus capers' 200-300mg per tablespoon.
Can I make my own caper substitute from nasturtium seeds?
Yes, pickle green nasturtium seeds in white wine vinegar with 2 tablespoons salt per cup of vinegar for 2-3 weeks. Use 1:1 ratio for capers. The flavor is peppery and tangy, closer to green peppercorns than true capers. Harvest seeds when they're young and green, about 6-8mm in size, before they harden.
