Slender hollow green stems from a small onion relative, with a mild allium bite and none of the sulphurous heat of a raw onion.
What it does in a recipe: A gentle onion note plus a green garnish, used raw or added at the very end because heat destroys both the colour and the flavour. Pick the swap that covers that job - the ratios below are written so you can act on them without doing any arithmetic.
Snip chives with scissors rather than chopping them with a knife. A blade crushes the hollow stems and squeezes out the liquid that carries the flavour.

Fresh chives in summary
Fresh chives at a glance: category, its job in a recipe, the diets it suits, the diets its substitutes can satisfy, and how many substitutes there are.
Can I use green onion tops instead of fresh chives?
1 tbsp sliced fresh chives = 1 tbsp thinly sliced green onion tops. Green onion greens are the same part of a closely related allium and carry the same mild sulphur compounds at a slightly higher concentration. A little stronger and coarser in texture, but visually and functionally very close.
Can I use garlic chives instead of fresh chives?
1 tbsp sliced fresh chives = 1 tbsp sliced garlic chives. Garlic chives are the flat-leaved sibling of the same plant, delivering the same green allium function with garlic rather than onion character. Noticeably garlicky. Good on eggs and dumplings, less appropriate scattered over a delicate potato soup.
Can I use dried chives instead of fresh chives?
1 tbsp sliced fresh chives = 1 tsp dried chives. The standard 3:1 fresh-to-dried conversion, though chives are among the herbs that lose the most in the drying. Very little onion flavour survives. They read as green flecks more than as a seasoning.
Can I use onion powder with fresh parsley instead of fresh chives?
1 tbsp sliced fresh chives = 1 tbsp chopped parsley + 1/8 tsp onion powder. Parsley supplies the green colour and freshness that chives contribute visually, while a small amount of onion powder restores the allium note. The onion note reads as cooked rather than fresh, and the texture is softer than the neat rings chives give.
Cooking around an allergy? Diet tags here describe the ingredient itself, not any particular brand. Processed products change formulation without notice and shared production lines are common, so read the label on everything you use. A severe allergy is a medical matter - confirm with the manufacturer or your clinician rather than relying on a substitution chart.
