Picture this: a hole dug into the earth, stones heated until they glow, aromatic leaves, meat, root vegetables, everything carefully layered and then sealed under soil… hours later, a fragrant cloud of steam rises as the pit is opened. This isn’t a scene from an adventure movie. It’s one of humanity’s oldest and most poetic cooking methods, still practiced today across the globe. Underground cooking also called earth-oven cooking — has been part of human culture for thousands of years. These dishes tell stories far beyond the plate: stories of community, respect for the land, transmission of knowledge, and flavors that no modern kitchen can fully replicate.
Surprisingly few food blogs and websites really dive into these traditions. We hear plenty about barbecue, wood-fired ovens, or sous-vide, but earth ovens remain relatively under the radar. That’s a shame, because these techniques deliver a sensory and cultural experience unlike anything else. Today we’re exploring five of the most captivating expressions of this ancestral art: the Māori hāngī of New Zealand, the Peruvian pachamanca, the Fijian lovo, the Chilean curanto, and Hawaiian kalua pig.
An Ingenious Technique Born of Necessity
Long before pottery or stone ovens existed, people around the world discovered that the earth itself could become a perfect oven. The method is remarkably consistent across cultures: dig a pit, heat stones (preferably volcanic or river stones that hold heat without exploding), place the food — often wrapped in leaves — on top, cover everything with more leaves, wet cloth, or vegetation, then seal it with soil. Time and trapped steam do the rest. The result is gentle, even cooking that renders meat fall-apart tender, concentrates flavors, and adds a subtle smoky, earthy note that’s impossible to fake.
This way of cooking is inherently communal. It takes time, teamwork, and space, making it ideal for large gatherings — weddings, festivals, ceremonies, or simply big family celebrations. In almost every culture that practices it, the moment the pit is opened becomes a shared ritual of anticipation and joy.
The Māori Hāngī: The Heart of New Zealand
In New Zealand, the hāngī (sometimes called umu) is more than a cooking method — it’s an expression of manaakitanga, the Māori value of hospitality and generosity. Polynesian ancestors brought this technique when they settled Aotearoa around 800 years ago. Today it still appears at major events on marae (traditional meeting grounds) and in cultural villages, especially in Rotorua, where geothermal activity sometimes allows cooking with natural steam.
The process is elegant in its simplicity. A pit is dug and a fire of manuka or kanuka wood is built to heat volcanic stones to 600–700 °C. Once the embers are cleared, baskets (traditionally woven from New Zealand flax leaves, now often wire or cloth) filled with meat — pork, lamb, chicken, sometimes seafood — and vegetables such as kūmara (sweet potato), potatoes, pumpkin, and cabbage are placed on the hot stones. Everything is covered with wet cloths and then soil to trap the steam. After three to four hours, the pit yields food with a melting texture and a distinctive smoky-earthy aroma that stays with you long after the meal.
What makes the hāngī truly special is its social dimension. Preparing one is a collective effort — people work together, share stories, and pass knowledge. Eating a proper hāngī is a way of understanding a little more of the Māori spirit.
Pachamanca: An Offering to Mother Earth in the Andes
In the central Andes of Peru, pachamanca (from Quechua pacha = earth and manka = pot) is nothing short of a ceremony. Declared a national cultural heritage in 2003, it is celebrated every first Sunday of February. Its roots stretch back well before the Incas, with archaeological evidence dating as far as 7,000–8,000 years.
Here, cooking is spiritual as much as practical. The hot stones represent Inti, the Sun God, and burying the food is an act of returning it to the womb of Pachamama, Mother Earth. Several meats (chicken, pork, beef, lamb, sometimes guinea pig) are marinated with local herbs such as huacatay and chincho, then layered with native potatoes, ocas, fava beans, corn, and humitas on the glowing stones. The pit is covered with leaves and soil and left for one to two hours.
When the earth is finally opened, steam rises carrying the scents of herbs and meat, and the sharing begins. Pachamanca is an act of gratitude — a reminder that food comes from the land and that the land deserves respect.
The Fijian Lovo: A Tropical Celebration
In Fiji, the lovo is the local version of the Polynesian earth oven, reserved for big occasions: weddings, festivals, and village celebrations. Preparation starts early. A pit is dug and large river stones are heated for hours. Meanwhile, meats (chicken, pork, fish) and root crops (taro, cassava, sweet potato) are wrapped in banana or palm leaves. Palusami — taro leaves stuffed with coconut — is a frequent and beloved addition.
Once the stones are white-hot, the parcels are layered into the pit, covered with more leaves and soil, and left to cook for one to two hours (longer for bigger quantities). The result is a smoky, juicy feast fragrant with coconut and tropical leaves. Lovo is usually served buffet-style on large banana leaves in a joyful, communal atmosphere — the spirit of the islands on a plate.
Curanto: Where Sea Meets Land on Chiloé
On the Chiloé Archipelago in southern Chile, curanto is one of the oldest continuously practiced cooking traditions in the Americas. Archaeological remains date back more than 11,000 years. The name comes from Mapudungun and means “hot stones.” Traditionally prepared as curanto en hoyo (in a pit), it brings together seafood, meat, potatoes, and local specialties such as milcaos and chapaleles (potato-based breads or dumplings).
Stones are heated in a pit about half a meter deep. Layers of mussels, clams, chicken, pork, sausages, and potatoes are arranged, separated by giant nalca (Chilean rhubarb) leaves. The pit is sealed with wet sacks and soil and cooks for roughly an hour and a half. Curanto is a true dialogue between sea and land — a dish of abundance and community that still unites families and neighbors for special occasions.
Hawaiian Kalua Pig: The Soul of the Luau
In Hawaii, kalua pig (or kālua pig) is the star of every traditional luau. “Kālua” literally means “to cook in an underground oven.” The oven itself is called an imu. Lava rocks are heated with kiawe wood (a local mesquite), a whole pig (or large cuts) is rubbed with Hawaiian sea salt, sometimes with hot stones placed inside the cavity, then wrapped in ti and banana leaves. The entire pit is sealed under earth for six to ten hours of slow cooking.
The meat emerges so tender it shreds with a fork, carrying a deep, smoky, slightly earthy flavor that is unmistakably Hawaiian. Modern home versions exist (oven or slow-cooker with a touch of liquid smoke), but nothing matches the real imu experience. Kalua pig embodies the Hawaiian spirit of sharing and celebration.
Why These Traditions Still Captivate Us
What unites all these underground cooking methods is far more than technique. It is the idea that cooking can be a ritual — a moment of connection with the earth, with other people, and with ancestors. In a world of microwaves and 15-minute deliveries, these dishes remind us of the value of patience and collective effort. They also produce textures and flavors that modern ovens struggle to match: extreme tenderness, preserved moisture, and that subtle note of smoke and soil.
These traditions continue to evolve. Some communities adapt them (using pots, conventional ovens, or geothermal heat in Rotorua), yet the spirit remains intact. They are still practiced for celebrations, taught to younger generations, and shared with visitors.
So the next time you travel to New Zealand, Peru, Fiji, Chile, or Hawaii, seek out the chance to taste one of these dishes. Your palate will thank you, and you’ll feel part of something larger than a meal — a living tradition that has connected people to the earth since the dawn of cooking.
These underground cuisines are living treasures. They deserve to be known, respected, and celebrated. And who knows — one day you might find yourself digging a small pit in your own garden, letting the earth cook for you.
