|
Isan food is a lively and unique part of Thai food, known for its bold flavors and fresh ingredients like herbs, spices, and grilled meats. It’s a true taste of the region’s culture and history. Let’s explore some must-try dishes and the stories behind them!
What is Isaan Food?
Isaan food originated in the Northeast of Thailand, a region known for its plateaus, hills, and vast plains, which are ideal for livestock farming. The Mekong, Chi, and Mun Rivers provide vital water resources for the area. Due to the region’s dry conditions, preservation techniques like fermenting fish, particularly the well-known ‘Pla ra’ (fermented fish sauce) are commonly used. Today, many of Isaan’s signature ingredients are exported worldwide and widely used as cooking condiments.
Key Flavors, Spices, and Ingredients in Isaan Cuisine
Isan food is known for its bold, distinct flavors, including the saltiness of fermented fish sauce called Pla ra, the spiciness of fresh and dried chilies, and the sourness from local fruits like tamarind and hog plum. Most dishes in Isaan cuisine are dry and hearty, offering a dynamic balance of flavors, but they typically avoid coconut milk. Pla ra is a key seasoning used in many dishes, including bamboo shoot soup, grilled meats, stews, chili pastes, and the popular green papaya salad.
In Northeast Thailand, Isaan people primarily eat sticky rice as their staple, paired with locally grown seasonal vegetables. Isaan cuisine features a variety of dishes, including popular favorites like green papaya salad, larb (minced meat salad), bamboo shoot soup, and Isaan-style sausages. The Isaan good also includes a wide range of unique ingredients, some not commonly found elsewhere, such as red ant eggs, grasshoppers, locusts, crickets, water bugs, frogs, monitor lizards, snakes, and field rats.
The Composition of Isaan Food
The organization of meals and cultural practices surrounding Isaan food, like in other regions, follow distinct traditions. For everyday meals, Isaan people use a ‘Pak Kao’ or rice tray, similar to the Northern region. For more formal occasions, an elevated tray called a ‘Khan Tok’ is used. Evening receptions for guests, known as ‘Ngaan Pha Khao Laeng’ (similar to the Northern ‘Ngaan Khan Tok’), feature sticky rice served in bamboo containers, allowing guests to pick and enjoy dishes by hand. For dishes with liquid, spoons are provided.
Varieties of Isaan Food
Isan food is full of variety, with different cooking methods that give each dish its unique flavor. The dishes can be grouped by the way they’re cooked, each showing a different part of the region’s food culture. Let’s take a look at these methods and the delicious dishes they create!

Jaew: The Bold and Flavorful Isaan Food
Authentic Isan food, like Jaew, is known for its bold, salty-spicy flavor. The spiciness typically comes from fresh chili peppers or chili powder.

Other types of chili, like cayenne pepper, cherry pepper, or young chili, can also be used, depending on personal preference for heat.
For those who enjoy intense spiciness, Isaan chili is a must, while those who prefer a milder heat with the essence of chili can choose cayenne or cherry pepper. The salty flavor in Isaan dishes is primarily derived from fermented fish sauce, which is a key seasoning, allowing the fish sauce to develop a rich, distinct taste.

In Isaan food, “soup” (Sup) refers to a type of spicy salad, with the name changing based on the main ingredient. For example, ‘Sup Hed’ is a spicy mushroom salad, ‘Sup Hoy’ is a spicy clam salad, ‘Sup Nomai’ is a spicy bamboo shoot salad, and ‘Sup Makeua’ is a spicy eggplant salad.
