Ayam Geprek Recipe | Indonesian Crispy Smashed Chicken in Sambal Bawang
Ayam Geprek (Crispy Smashed Chicken in Sambal)
Indonesia's viral street food from Yogyakarta: chicken in a shatteringly crisp battered crust, smashed straight into a raw garlic-and-chili sambal bawang so the crust soaks up the heat. Fiercer, crunchier, and younger than its cousin ayam penyet.
Ingredients
- 4 boneless chicken breasts or 8 boneless thighs (about 800g / 1¾ lb)
- 1 teaspoon salt
- 1 teaspoon garlic powder
- ½ teaspoon ground coriander
- ½ teaspoon white pepper
- 2 eggs, beaten
- 150g (1¼ cups) plain flour (all-purpose)
- 50g (⅓ cup) rice flour (for extra crunch)
- 1 teaspoon baking powder
- 500ml (2 cups) neutral oil for deep frying
- 12 bird's eye chilies (cabe rawit) - reduce to 6 for medium heat
- 6 cloves garlic, peeled
- 2 shallots, peeled (optional, for sweetness)
- ½ teaspoon salt
- ¼ teaspoon sugar
- 3 tablespoons of the hot frying oil
- Steamed white rice
- Fresh cucumber slices
- Fried tofu or tempeh (optional)
- Extra sambal for the brave
Instructions
- 1
Butterfly each chicken breast (or flatten thighs) to an even 2cm thickness. Season all over with salt, garlic powder, coriander, and white pepper. Rest for 10 minutes.
- 2
Set up your coating station: beaten eggs in one bowl; plain flour, rice flour, and baking powder whisked together in another.
- 3
Dip each piece of chicken in egg, then press firmly into the flour mix. For the signature craggy crust, sprinkle a few drops of water into the flour and press the chicken in again.
- 4
Heat oil to 170°C (340°F) in a wok or deep pot. Fry the chicken in batches for 6-8 minutes until deep golden and crunchy, and the internal temperature reaches 75°C (165°F).
- 5
Drain the chicken on a wire rack (not paper towels) so the crust stays crisp. Keep 3 tablespoons of the hot frying oil.
- 6
Make the sambal bawang: in a mortar (cobek), coarsely pound the bird's eye chilies, garlic, shallots, salt, and sugar. Keep it rough and chunky - not a smooth paste.
- 7
Pour the 3 tablespoons of hot frying oil over the pounded sambal. It will sizzle and bloom - this cooks the raw edge off the garlic and chilies while keeping them fresh and fierce.
- 8
Place one piece of fried chicken directly on top of the sambal in the mortar. Press and lightly smash with the pestle so the crust cracks and drags the sambal into every crevice.
- 9
Turn the chicken once so both sides are coated in sambal, giving it one or two more presses. Repeat with the remaining pieces, adding sambal as needed.
- 10
Serve immediately over steamed rice with cucumber slices, spooning any sambal left in the mortar over the top.

Interactive Cooking Guide
Master the crispy crust and the geprek smash with step-by-step guidance from Chef Yossie
Butterfly each chicken breast (or flatten thighs) to an even 2cm thickness. Season all over with salt, garlic powder, coriander, and white pepper. Rest for 10 minutes.
Equipment needed:
Chef's Tip:
Even thickness is everything - it means the chicken cooks through in the same time the crust takes to brown.
Set up your coating station: beaten eggs in one bowl; plain flour, rice flour, and baking powder whisked together in another.
Equipment needed:
Chef's Tip:
Rice flour is the crunch insurance - it fries up harder and stays crisp under wet sambal far longer than plain flour alone.
Dip each piece of chicken in egg, then press firmly into the flour mix. Sprinkle a few drops of water into the flour and press the chicken in again for a craggy crust.
Chef's Tip:
Those little wet-flour clumps you press on become the shattering crispy bits - don't skip this step.
Heat oil to 170°C (340°F) in a wok or deep pot. Fry the chicken in batches for 6-8 minutes until deep golden and cooked through to 75°C (165°F).
Equipment needed:
Chef's Tip:
Fry in two batches so the oil temperature holds - crowded oil means a pale, greasy crust.
Important:
Hot oil is dangerous. Lower the chicken away from you and never leave the pan unattended.
Drain the chicken on a wire rack so the crust stays crisp. Reserve 3 tablespoons of the hot frying oil for the sambal.
Equipment needed:
Chef's Tip:
A rack lets steam escape downwards. On paper towels the crust steams itself soft in minutes.
In a mortar, coarsely pound the bird's eye chilies, garlic, shallots, salt, and sugar. Keep it rough and chunky - not a smooth paste.
Equipment needed:
Chef's Tip:
Chunky is authentic. You want visible flecks of chili and garlic clinging to the crust, not a sauce.
Pour the reserved hot frying oil over the pounded sambal. It will sizzle and bloom.
Chef's Tip:
This is the flavour moment - hot oil takes the raw harshness off the garlic while the chilies stay bright and fierce.
Important:
The oil will spit when it hits the wet sambal - pour slowly and stand back.
Place one piece of fried chicken directly on top of the sambal in the mortar. Press and lightly smash with the pestle so the crust cracks and drags the sambal in.
Equipment needed:
Chef's Tip:
This is the 'geprek'. Firm presses, not blows - crack the crust so it drinks up the sambal.
Turn the chicken once so both sides are coated, giving it one or two more presses. Repeat with the remaining pieces.
Chef's Tip:
Work one piece at a time and serve as you go - geprek waits for no one.
Serve immediately over steamed rice with cucumber slices, spooning any sambal left in the mortar over the top.
Equipment needed:
Chef's Tip:
The full warung experience: rice, geprek chicken, cold cucumber, and iced sweet tea to put out the fire.

The Geprek Phenomenon
Ayam geprek is the rare dish whose birthplace is known to a single warung: Bu Rum's stall in Yogyakarta, where in the early 2000s a student asked for her crispy fried chicken to be crushed together with sambal. The result — battered crust shattered into raw garlic-chili sambal — spread through Yogyakarta's student quarters, then across all of Indonesia, until "geprek" chains stood on every high street.
Where ayam penyet is a traditional East Javanese dish with a marinated, spice-rubbed chicken, geprek is proudly modern: the chicken is Western-style crispy fried chicken, and everything depends on the collision between that crust and the sambal bawang. Cheap, fast, violent with heat — it is Indonesian student food perfected, and it deserves its global moment.
Geprek vs Penyet: Know Your Smashed Chicken
Ayam Geprek
- • Crispy battered (flour-crusted) fried chicken
- • Smashed directly INTO the sambal
- • Sambal bawang: raw chili + garlic + hot oil
- • Born in Yogyakarta, early 2000s
- • Order by chili count at warungs
Ayam Penyet
- • Spice-marinated fried chicken, no batter
- • Pressed lightly, sambal served alongside
- • Sambal terasi or oelek, often cooked
- • Traditional East Javanese street food
- • Served with lalapan vegetables
How Indonesians Eat Geprek
The warung order: a scoop of hot rice, the geprek chicken straight from the mortar with all its sambal, cold cucumber, and — critically — es teh manis (iced sweet tea). At geprek chains you specify your chili count when ordering, and 15+ earns respectful nods.
The mozzarella era: around 2017, warungs began blanketing geprek in melted mozzarella, and "geprek mozza" became a national obsession. Purists grumble; students queue. Try it once — the cheese genuinely tames the burn between bites.
The Indomie move: replace the rice with instant noodles and you have the definitive Indonesian student dinner. We won't judge.
