Kiwi onion dip is a type of dipping sauce eaten in New Zealand. Often referred to as 'kiwi dip', 'onion dip' or 'original kiwi dip', it consists of a packet of powdered onion soup stirred into a can of reduced cream, which is then left to refrigerate and thicken, and is often then garnished with lemon juice and sometimes parsley. "Kiwi" refers to this being a New Zealand dish as opposed to the dip containing kiwifruit nor any kiwi (bird) products. Served alongside potato chips, crackers, or chopped vegetables, the dip is a popular dish at parties, barbeques, and other social occasions. A small amount of vinegar or lemon juice can be added to the dip for flavour.

Kiwi onion dip's creation has been credited to Rosemary Dempsey, a home economist for Nestlé New Zealand in the 1950s or 60s.^[1]

The dip has assumed an iconic status in New Zealand cuisine. In February 2019 Nestlé released a campaign bannered "Kiwi as", aligning the dip with canonical moments in New Zealand popular culture.^[2] Lauraine Jacobs, a food writer, has said Kiwi onion dip is an “all-time classic”. “My mother made it. My son and his wife make it, and think themselves clever. So now it is the darling of yet another generation."^[1] The dip is often missed by New Zealanders living abroad who may not have access to reduced cream, a dairy product only widely available in their home country.^[3] In 2019 it was reported cans of reduced cream are commonly found in the suitcases of New Zealanders as they travel overseas.^[4]

In April 2019, Countdown supermarket announced the introduction of 'NZ Onion Dip Icecream', a two-litre tub of ice cream flavoured with caramelised onions and reduced cream. The product was later declared by the supermarket to be an April Fools' joke.^[5]
