One of the most famous snacks in Indonesia is batagor, a fried fish dumpling served in a traditional spicy sauce. It has roots in the Chinese culinary tradition, which has left a trace on many Indonesian dishes. Although this famous snack is reminiscent of the more famous Chinese dumpling, its distinguishable characteristic is that it is fried, not steamed.

The most common fish used to make the dish is wahoo, but tuna, mackerel, and even prawns can also be used. Potatoes, tofu, or cabbage are also occasionally added to the dish. Batagor is the perfect snack because of the way it is served. When fried, the dumplings are cut into small bite-sized pieces and covered in peanut, soy, and chili sauce with a splash of lime juice. 

Fried bananas or plantains are a common everyday snack eaten throughout Indonesia. They come in numerous versions in which the fruit is simply fried in shallow oil, but more often sliced banana pieces are coated in batter before they are fried until golden.

Besides numerous other varieties, fried bananas also appear under different names such as godoh biu on Bali or gedhang gorèng on Java. They are traditionally sold at street stalls and carts and belong to a group of gorengan dishes—Indonesian deep-fried snacks. 

Pempek is a traditional fish cake made with ground fish meat and tapioca. The actual origin of this dish is the city of Palembang, situated in the South Sumatra province. The origin story of pempek says that an old Palembang citizen was tired of the traditional fried or grilled fish, so he thought of an innovative way to ground the meat, mix it with tapioca flour, and deep-fry it to get a crunchy and delicious snack.

He then used to cycle through the city and sell the fish cakes to Palembang citizens. Over time, pempek was recognized as a praise-worthy snack, and today it is considered to be a traditional Indonesian delicacy. These round or rectangular cakes are usually steamed, and right before serving they are fried in vegetable oil and cut into bite-sized pieces. 

Kripik are small chips from Indonesia, prepared in sweet and savory versions. They are made with fish, vegetables, or fruit, in some cases the exotic ones such as taro, breadfruit, jackfruit, and snake fruit. The chips are deep-fried in vegetable oil until crispy.

The most popular varieties include kripik singkong (cassava chips) and kripik pisang (banana chips). Kripik belongs to the group of krupuk, which are larger chips, while kripik is smaller, but has more variety in its ingredients, so almost any fruit, tuber, vegetable, or nut can be incorporated into kripik. 

Gorengan is a generic name that refers to a wide group of Indonesian deep-fried snacks that can be prepared with a variety of ingredients. Whether savory or sweet, the fritters usually combine egg batter with various additions such as bananas, tempeh, tofu, sweet potatoes, or jackfruit.

The ingredients can be finely sliced and incorporated into the batter or merely dipped before they are fried. Gorengan is one of the most common Indonesian street food items that is sold at numerous markets throughout the country. Although they come in a seemingly endless number of combinations, some of the most popular varieties include pisang goreng (bananas), ubi goreng (sweet potato), aci goreng (fried tapioca dough), tahu goreng (fried tofu), and singkong goreng (fried cassava).

Tempeh mendoan is a variety of fried tempeh that hails from Purwokerto. Thin slices of tempeh—fermented soybean product—are dipped in batter that is enriched with ground coriander, sliced scallions, and garlic before they are deep-fried.

This tempeh variety is only shortly fried, creating a crispy outer layer, while the tempeh remains soft and juicy. The name of the dish stems from Banyumasan language in which mendo roughly translates as half-cooked. This tempeh is best served with sambal, other types of chili-based dips, or kecap manis—Indonesian sweet soy sauce. 

Otak-Otak is a Southeast Asian snack, usually associated with Indonesia and Malaysia. The main ingredient of the dish is ground fish paste. Ikan tenggiri (wahoo) is most commonly used in Indonesia, while mackerel is the most popular choice in Malaysia.

Also, bandeng (milkfish) and ikan belida (featherback fish) may also be used. In Indonesia, the mixture consists of ground fish, shallots, garlic, scallions, eggs, coconut milk, and either sago or tapioca starch. The Malaysian and Singaporean versions have a distinct orange or brownish color, due to the addition of turmeric, curry powder, or chili.
