Dill is a commonly used herb, in everything from salads and pickles to soups, but here are the best dill substitutes for when you don't have it on hand. These are my top choices.
With a similarly bright flavour and slight anise tone, finely chopped basil is an excellent 1:1 substitute for dill in almost any usage. It won't look like basil, but you can mix it with fennel fronds to get that characteristic appearance without too much liquorice flavour.
Basil
Tarragon
With a stronger liquorice flavour, I recommend subbing about half the amount that's called for if using in place of dill. Tarragon is particularly good with potatoes.
