Ingredients
Rendang Paste
- 1Carolina Reaper pepper, fresh, stem removed
- 8dried chilies, soaked and deseeded
- 6 clovesgarlic
- 2 inchgalangal, peeled
- 2 inchginger, peeled
- 3 stalkslemongrass, tender parts only
- 4shallots, peeled
- 1 tspturmeric powder
- 2 tbsptamarind paste
Rendang
- 2 lbschuck roast, cut into 2-inch cubes
- 1 cancoconut milk, 400ml, full-fat
- 2 tbsppalm sugar, or brown sugar
- 2 tspsalt
- 4makrut lime leaves
- 3 tbspvegetable oil
Coconut Sambal
- 1/2 cupcoconut cream, thick part from can top
- 1 tbsplime juice, fresh
- 1 tspsalt
- 1 tbsppalm sugar
Assembly
- 4roti canai, or naan bread
- 1cucumber, sliced thin
- 1 cupbean sprouts, blanched
- 1/4 cupcilantro leaves
- 1/4 cupmint leaves
Method
1. Build your rendang paste Combine all the paste ingredients in a food processor with 2-3 tablespoons water and process until completely smooth, scraping down the sides as needed. You're looking for a thick but spreadable paste with no visible chunks.
Watch for: paste turns a deep, rich red and releases an intense, complex aroma
Tip: Please wear gloves when handling that Carolina Reaper and work in a well-ventilated space – trust us on this one
2. Fry the paste and brown the beef Heat oil in a heavy pot over medium heat and fry the paste for 8-10 minutes, stirring constantly to prevent burning. Add the beef cubes and sear on all sides until they develop a beautiful golden crust.
Watch for: paste darkens and becomes deeply aromatic, beef develops a golden-brown crust all over
Tip: You'll know the paste is ready when oil starts separating around the edges and that raw, harsh smell mellows into something fragrant
3. Slow-cook until perfect Add coconut milk, palm sugar, salt, and lime leaves to the pot. Bring to a gentle boil, then reduce heat to low and simmer uncovered for 2.5-3 hours, stirring occasionally, until the beef is fork-tender and the sauce has reduced to a thick, dark coating.
Watch for: sauce reduces to a thick, dark coating that clings to the meat, and beef falls apart at the touch of a fork
Tip: The rendang is perfectly done when you can shred the beef with a fork and the sauce clings to the meat rather than pooling
4. Bring it all together Toast the roti until golden and crisp, then whisk together your coconut sambal ingredients until smooth. Shred the rendang beef with two forks, spread sambal generously on the roti, pile on that gorgeous shredded rendang, and crown with cucumber, bean sprouts, and fresh herbs.
Watch for: roti turns golden and crisp, beef shreds effortlessly with gentle pressure
Tip: Let the rendang cool just a bit before shredding – those beef pieces will be molten hot
Equipment
- food processor
- heavy-bottomed pot
- wooden spoon
- disposable gloves
Make ahead
- The rendang can be made up to 3 days ahead and refrigerated – honestly, it gets even better as those flavors meld together. Just reheat gently before assembling your burgers.
Storage
- Leftover rendang keeps beautifully in the refrigerator for up to 5 days, or you can freeze it in portion-sized containers for up to 3 months.
Reheat
- Warm the rendang gently in a saucepan over low heat, adding just a splash of coconut milk if the sauce seems too thick.
Top tips
- The rendang actually tastes better after a day or two in the fridge – those flavors really have time to get acquainted
- Start with just a tiny piece of Carolina Reaper and taste before adding more – you can always add heat, but you can't take it back
- Keep a glass of milk or coconut milk close by while eating – water won't do you any favors at this heat level
Substitutions
- Beef short ribs work beautifully instead of chuck roast and give you even richer flavor
- If you can't find roti canai, soft brioche buns make a decent substitute
- Brown sugar works just fine in place of palm sugar – use the same amount
Serve with
- Put extra coconut sambal on the table – people will want more of that cooling contrast
- Malaysian iced tea makes the perfect cooling companion to this fiery burger
- A side of pickled vegetables offers another layer of cooling relief

Why this recipe works
Editorial notes before you cook
When you want to honor the soul-warming tradition of Malaysian beef rendang but turn the heat dial all the way up, this burger delivers both authentic flavor and serious fire. The Carolina Reaper brings nuclear intensity to the already complex blend of galangal, lemongrass, and coconut milk, while the slow-cooked beef becomes meltingly tender and almost jammy. Fresh cucumber and herbs offer blessed relief against the soft roti bun – though honestly, you'll need all the cooling help you can get.
The goal here is not just heat. It is contrast, pacing, and texture: enough richness to feel satisfying, enough brightness to keep the plate moving, and enough chile character that the spice actually tastes like something.

FAQ
The repeat questions
How can I dial back the heat level?
Start with just a tiny sliver of Carolina Reaper, or better yet, substitute 2-3 habanero peppers for intense heat that won't send you to the emergency room.
Can I use store-bought rendang paste?
Absolutely – use about 4 tablespoons of good-quality rendang paste and blend in your Carolina Reaper separately. It's a real time-saver.
Why is my rendang still soupy after hours of cooking?
Keep cooking it uncovered on low heat – traditional rendang should be quite dry, with the sauce clinging to the meat like a thick glaze rather than pooling around it.
