Green olives substitutes

Brined flower buds of the caper bush. Drain, and chop the larger ones roughly so they distribute the way olive pieces would.

Best for

puttanesca, chicken piccata, tapenade, pasta sauces, fish, potato salad

The best swap for cooking because it is doing precisely the same work, delivering concentrated salt plus a green vegetal bitterness that cuts richness. Capers are more floral and mustardy and considerably more intense per spoonful, which is why you use a third of the volume. What you lose is the substantial meaty chew of an olive, so a chicken braise made with capers tastes right but has nothing to bite into. Caper berries, the stalked ones the size of a small olive, solve that and make a decent martini garnish too.

Purple-black brine-cured olives, pitted and roughly chopped or left whole depending on the recipe.

Best for

braises, chicken with olives, pasta, salads, tapenade, stews

The easiest and most available swap, and in any cooked dish it is a good one. The differences are real but forgivable: black brine-cured olives are riper, so they taste fruitier, winier and slightly sweeter with far less of green olive's crisp bitterness, and they are noticeably softer so they collapse into a braise instead of holding their shape. Your dish will also look darker, which matters in something pale like a chicken with olives and lemon. In a martini or a stuffed olive tray, this is the wrong olive.

Chop small, drain properly, and press between kitchen paper so the extra brine does not water down a dressing or a sandwich spread.

Best for

muffuletta, olive salad, relish, potato salad, tartare sauce, charcuterie boards

This is a genuine winner in cold dishes and a poor idea in hot ones. In a muffuletta olive salad or a relish it gives you the identical salty crunch and acidic bite, and most people will not question it. The tell is flavour direction: cucumber pickles bring vinegar, dill and garlic where green olives bring fruit and bitterness, so anything Mediterranean and simmered will taste distinctly of a delicatessen instead. Use three quarters as much and add a little olive oil to put some of the fat back.

Mild pickled peppers from a jar, stems removed and sliced into rings or chopped.

Best for

Italian salads, muffuletta, sandwiches, antipasto, pizza, Greek salad

Very good in cold Mediterranean-adjacent dishes, because they are salty, tangy and pleasantly bitter around the skin, and they bring a low background heat that most people read as a plus. They are much softer than a firm green olive, closer to slippery than snappy, and slightly sweeter, so a salad made with them loses the firm bite that punctuates a plate. In a cooked braise they turn to mush; add them off the heat.

The bright green buttery Sicilian olive, or any mild green olive such as Cerignola or Picholine, pitted and used as the recipe directs.

Best for

salads, antipasto, roast chicken, pasta, eating plain, cheese boards

If what your recipe wanted was the sharp salty Manzanilla-type olive and what you have is a mild one, you are almost there but not quite. Castelvetrano is markedly less salty, less bitter and noticeably buttery and sweet, with a softer, more yielding flesh. A puttanesca made with it comes out oddly gentle and undersalted. A pinch of salt or a spoonful of caper brine restores the seasoning, and a squeeze of lemon puts back some of the missing bite.

Jarred or canned artichoke hearts, drained hard, patted dry and chopped to olive-sized pieces.

Best for

pasta, salads, sandwiches, pizza, cooking for people who dislike olives

The obvious choice when the reason you are substituting is that someone at the table hates olives. Artichokes give you body, a mild tang and a soft vegetal bitterness that reads as broadly Mediterranean. What they do not give you is salt, and that is the main thing green olives contribute, so you must season deliberately or the dish will taste flat and slightly sweet. Texture is tender rather than firm.

Swap the garnish rather than pretending to replace it. A pickled pearl onion turns a martini into a Gibson; a lemon twist turns it into a twist martini.

Best for

martinis, Gibsons, cocktail garnishes, Bloody Marys

This is the honest answer for a drink: nothing substitutes for a green olive in a martini, because the olive is contributing a specific salty bitter-green aroma and a savoury edge to the vermouth that nothing else copies. A cocktail onion is savoury and sharp and makes an excellent, historically legitimate drink that tastes different rather than worse. A lemon twist takes the drink in the opposite direction, bright and aromatic instead of savoury. A caper berry is the closest thing to a true stand-in.
