This burger puts a homemade rendang spice paste — cooked-down onion, lemongrass, ginger, and warm spices — directly into the beef patty, so the flavor is baked in rather than just sitting on top. It takes about 70 minutes start to finish, and most of that is hands-off paste cooling time. If you like a burger with real heat and depth, this one delivers.
The short version of why this works
Two things make this recipe click. First, you cook the spice paste before it goes into the patty. Raw onion and lemongrass in ground beef stay harsh and wet; sautéing them until golden concentrates their flavor and drives off moisture, which means your patties hold together on the grill instead of falling apart. Second, the coconut milk in the patty mix keeps the beef from drying out during the 4–5 minute cook time per side — it acts like a small amount of fat insurance. Neither step is complicated, but skipping either one will cost you.
About the ingredients
- Lemongrass: Use only the bottom 4–5 inches of the stalk — the pale, tender part. The outer layers are woody; peel them off before mincing. Frozen minced lemongrass from an Asian grocery works fine here and saves prep time.
- Galangal: Traditional rendang uses it, but this recipe doesn’t call for it. If you have it, swap half the ginger for galangal — it adds a sharper, more piney note. If you don’t, don’t stress.
- Thick coconut milk: Shake the can and spoon from the top if it has separated. Thin coconut milk (or coconut water) won’t give you the same result.
- Peanut sauce: Listed as optional, but it’s worth making. Even a quick store-bought satay sauce cuts the heat from the cayenne and adds contrast. Skip the egg in the mix — it makes the patty mushy and the paste already provides enough binding.
- Ground beef: 80/20 fat ratio is the practical choice. Leaner beef dries out fast at medium-high heat, especially with the short cook time.
Make-ahead notes
The rendang spice paste keeps in an airtight container in the fridge for up to 5 days, so you can make a double batch on the weekend and pull it out on a weeknight. Formed raw patties (with paste already mixed in) can be refrigerated for up to 24 hours, covered tightly — any longer and the lime zest starts to affect the texture of the beef. For freezing, freeze the patties before adding the paste: mix paste into fresh beef the day you cook. If you do freeze fully mixed patties, use them within 6 weeks and thaw overnight in the fridge, not on the counter. Cooked patties reheat well in a covered skillet over low heat with a splash of water — about 3 minutes per side — without drying out.
Mistakes to avoid
- Not cooling the paste before mixing it into the beef: Hot paste starts cooking the raw egg and meat as you mix. Give it at least 10 minutes off the heat, or spread it on a plate to cool faster.
- Overworking the patty mixture: Mix until just combined. Overhandling ground beef tightens the proteins and gives you a dense, tough patty.
- Patties that are too thick: Keep them to about ¾ inch. Thicker patties take longer to reach 160°F (71°C) internal temperature and the outside can char before the center is safe.
- Skipping the thermometer: The spice paste makes the beef look darker than usual as it cooks, so color alone is not a reliable doneness cue. Use an instant-read thermometer and pull at 160°F (71°C).
- Wet buns: If you’re adding cucumber, pat the slices dry with a paper towel first. Excess moisture soaks into the bottom bun fast and makes it fall apart before you’re halfway through.

Ingredients
Rendang Spice Paste
- 3 tbsp coconut oil for sautéing
- 1 cup onion thinly sliced
- 5 cloves garlic minced
- 1 inch ginger grated
- 2 tbsp lemongrass minced
- 2 tbsp ground coriander
- 1 tsp ground cumin
- 1 tsp ground turmeric
- 1 tsp cayenne pepper adjust to taste
Burger Patties
- 500 g ground beef grass-fed if possible
- 1 medium egg lightly beaten
- 1 tsp lime zest freshly grated
- 2 tbsp coconut milk thick
- 0.5 cup rendang spice paste prepared
- 1 pinch salt to taste
- 1 pinch ground black pepper freshly ground
Burger Assembly
- 4 pieces burger buns toasted
- 4 small lettuce leaves
- 1 small cucumber thinly sliced
- 4 tbsp peanut sauce optional topping
Instructions
- Prepare the Rendang Spice Paste: Heat the coconut oil in a skillet over medium heat. Add sliced onions and sauté until caramelized and golden brown. Add the minced garlic, grated ginger, and minced lemongrass, cooking until fragrant. Stir in the ground coriander, cumin, turmeric, and cayenne pepper, cooking for another 2 minutes until the spices become aromatic. Allow to cool slightly before blending into a smooth paste using a mortar and pestle or food processor.
- Prepare the Burger Patties: In a bowl, combine the ground beef, beaten egg, lime zest, coconut milk, and prepared rendang spice paste. Mix well with hands until just combined. Season with salt and freshly ground black pepper. Form the mixture into four equal-sized patties.
- Cook the Patties: Preheat a grill or frying pan over medium-high heat. Cook the patties for 4-5 minutes on each side, or until they reach your desired degree of doneness.
- Assemble the Burgers: Toast the burger buns on the grill or in a pan. Spread a thin layer of peanut sauce, if using, on the bottom bun. Layer with a lettuce leaf, some cucumber slices, and the cooked beef patty. Top with the second half of the bun.

FAQ
Can I make the spice paste in advance?
Yes — the paste keeps in the fridge for up to 5 days in a sealed container. Making it ahead is actually the fastest way to get this burger on the table on a busy night, since the paste step takes the most active cooking time.
How spicy is this burger?
At 1 teaspoon of cayenne across four patties, it’s noticeable but not aggressive — roughly a medium heat level. Cut the cayenne to ½ teaspoon for mild, or push it to 1½ teaspoons if you want real heat.
Can I cook these on a stovetop instead of a grill?
A cast iron or heavy skillet over medium-high heat works just as well. The paste has enough oil in it that you don’t need to grease the pan, but make sure the pan is fully preheated before the patties go in or they’ll stick.
What can I use instead of peanut sauce if there’s a nut allergy?
Sunflower seed butter thinned with a little soy sauce and lime juice is a close substitute. A simple sriracha mayo also works and takes about 30 seconds to make.
Do I need a food processor to make the paste smooth?
No — a mortar and pestle works, and so does just leaving the paste slightly chunky. The onion breaks down enough during sautéing that the texture in the finished patty is barely noticeable either way.
