The cuisines of Oceania include those found on Australia, New Zealand, and New Guinea, and also cuisines from many other islands or island groups throughout Oceania.

Abelmoschus manihot, the aibika, is a flowering plant in the family Malvaceae. It was formerly considered a species of Hibiscus, but is now classified in the genus Abelmoschus. The plant is also known as the sunset muskmallow, sunset hibiscus, or hibiscus manihot.

Breadfruit is a species of flowering tree in the mulberry and jackfruit family (Moraceae) believed to be a domesticated descendant of Artocarpus camansi originating in New Guinea, the Maluku Islands, and the Philippines. It was initially spread to Oceania via the Austronesian expansion. It was further spread to other tropical regions of the world during the Colonial Era. British and French navigators introduced a few Polynesian seedless varieties to Caribbean islands during the late 18th century. Today it is grown in some 90 countries throughout South and Southeast Asia, the Pacific Ocean, the Caribbean, Central America and Africa. Its name is derived from the texture of the moderately ripe fruit when cooked, similar to freshly baked bread and having a potato-like flavor.

Cooking bananas are banana cultivars in the genus Musa whose fruits are generally used in cooking. They may be eaten ripe or unripe and are generally starchy. Many cooking bananas are referred to as plantains or green bananas. In botanical usage, the term "plantain" is used only for true plantains, while other starchy cultivars used for cooking are called "cooking bananas". True plantains are cultivars belonging to the AAB Group, while cooking bananas are any cultivars belonging to AAB, AAA, ABB, or BBB groups. The currently accepted scientific name for all such cultivars in these groups is Musa × paradisiaca. Fe'i bananas from the Pacific Islands are often eaten roasted or boiled, and are thus informally referred to as "mountain plantains," but they do not belong to any of the species from which all modern banana cultivars are descended.

Cyrtosperma merkusii or giant swamp taro, is a crop grown throughout Oceania and into South and Southeast Asia. It is a riverine and "swamp crop" similar to taro, but "with bigger leaves and larger, coarser roots." There are no demonstrably wild populations today, but it is believed to be native to Indonesia. It is known as puraka in Cook Islands, lak in Yap, babai in Kiribati, pula’a in Samoa, via kan in Fiji, pulaka in Tokelau and Tuvalu, simiden in Chuuk, swam taro in Papua New Guinea, navia in Vanuatu and palawan in the Philippines.
An earth oven, ground oven or cooking pit is one of the simplest and most ancient cooking structures. At its most basic, an earth oven is a pit in the ground used to trap heat and bake, smoke, or steam food. Earth ovens have been used in many places and cultures in the past, and the presence of such cooking pits is a key sign of human settlement often sought by archaeologists. Earth ovens remain a common tool for cooking large quantities of food where no equipment is available. They have been used in various civilizations around the world and are still commonly found in the Pacific region to date.

Kava or kava kava is a crop of the Pacific Islands. The name kava is from Tongan and Marquesan, meaning 'bitter'; other names for kava include ʻawa (Hawaiʻi), ʻava (Samoa), yaqona or yagona (Fiji), sakau (Pohnpei), seka (Kosrae), and malok or malogu. Kava is consumed for its sedating effects throughout the Pacific Ocean cultures of Polynesia, including Hawaii, Vanuatu, Melanesia, and some parts of Micronesia, such as [Pohnpei & Kosrae]. Kava can be used for medicinal purposes to treat anxiety.

Laulau, otherwise known as Lū in Tonga, Palusami in Fiji and Samoa and Rukau in the Cook Islands, is a Polynesian dish consisting of cooked taro leaves containing fillings such as pork, fish or coconut cream. In old Hawaiʻi, laulau was assembled by taking a few leaves and placing a few pieces of fish and pork in the center. In modern times, the dish uses taro leaves, salted butterfish, and either pork, beef, or chicken and is usually steamed on the stove. Laulau is a typical plate lunch dish and is usually served with a side of rice and macaroni salad.

Limu, otherwise known as rimu or ʻimu is a general Polynesian term for edible plants living underwater, such as seaweed, or plants living near water, like algae. In Hawaii, there are approximately one hundred names for kinds of limu, sixty of which can be matched with scientific names. Hundreds of species or marine algae were once found in Hawaii. Many limu are edible, and used in the cuisine throughout most of Polynesia.

Lūʻau, known alternatively as Poulet fafa in French Polynesia, Rourou in Fiji and Rukau in the Cook Islands is a traditional Polynesian stew. The name of this dish in Hawaii and other parts of the pacific is derived from its main ingredient, Taro leaves, which are cooked down and coconut milk added. Variations of this dish differ between islands. In Hawaii, octopus is added to this dish alongside onion and garlic, the dish being referred to as Squid Lū'au.

Ota ika is a Polynesian dish consisting of raw fish marinated in citrus juice and coconut milk. The Tongan, Tahitian, and Samoan variants are essentially identical in that the raw fish is briefly marinated in lemon or lime juice until the surface of the flesh becomes opaque. The fish is then mixed with coconut milk and diced vegetables. This is the national dish of Tonga.

ʻotai is a drink which originated in western Polynesia and is usually made as a refreshing accompaniment to large meals.

Pandanus tectorius is a species of Pandanus (screwpine) that is native to Malesia, eastern Australia, and the Pacific Islands. It grows in the coastal lowlands typically near the edge of the ocean. Common names in English include thatch screwpine, Tahitian screwpine, hala tree, pandanus, and pu hala in Hawaiian. The fruit is sometimes known as hala fruit.

Poi or Popoi is a traditional staple food in the Polynesian diet, made from starchy vegetables, usually breadfruit, taro or plantain.

Sago is a starch extracted from the spongy centre, or pith, of various tropical palm stems, especially those of Metroxylon sagu. It is a major staple food for the lowland peoples of New Guinea and the Moluccas, where it is called saksak, rabia and sagu. The largest supply of sago comes from Southeast Asia, particularly Indonesia and Malaysia. Large quantities of sago are sent to Europe and North America for cooking purposes. It is traditionally cooked and eaten in various forms, such as rolled into balls, mixed with boiling water to form a glue-like paste (papeda), or as a pancake. Sago is often produced commercially in the form of "pearls". Sago pearls can be boiled with water or milk and sugar to make a sweet sago pudding. Sago pearls are similar in appearance to the pearled starches of other origin, e.g. cassava starch (tapioca) and potato starch, and they may be used interchangeably in some dishes.
Colocasia esculenta is a tropical plant grown primarily for its edible corms, a root vegetable most commonly known as taro, kalo, dasheen, madhumbe, marope, magogoya, patra, arbi or godere. It is the most widely cultivated species of several plants in the family Araceae that are used as vegetables for their corms, leaves, and petioles. Taro corms are a food staple in African, Oceanic, and South Asian cultures, and taro is believed to have been one of the earliest cultivated plants.
