23 foods Food and drink Checked 9 Oct 2026

Here are 23 foods that start with O, each with a one-line description so you can tell what it is. The best-known ones come first, then the full list in A to Z order.

O opens with a strong trio, orange, olive and onion, and then branches out. Onion alone shows up in onion ring, onion bagel, onion roll and onion salt, so one word unlocks many answers. Oats appear as oat, oatmeal and oatmeal cookie.

Seafood fans have oyster, oyster stew and octopus. Okra is a long green pod often used in Southern stews, and oregano is a common pizza herb. Orzo is a small rice-shaped pasta, which makes a good surprise answer. In total the list has a little over twenty entries.
