This is a tempeh burger seasoned with soy sauce, coriander, shallots, and garlic, topped with a quick blended sambal made from fresh chilies, tomato, lime, and palm sugar. It comes together in 45 minutes, it’s fully plant-based, and it delivers 27 grams of protein per burger. If you want a veggie burger that actually tastes like something, this one earns its place on the grill night rotation.
The short version of why this works
Two things make or break this burger. First, crumble the tempeh finely — chunks leave air pockets and the patty falls apart in the pan. The finer the crumble, the more surface area absorbs the soy sauce and coriander, and the better the patty holds together when you flip it. Second, let the formed patties rest in the fridge for 15 minutes before cooking. Cold patties firm up and stay intact in the hot coconut oil instead of spreading into a mess. The sambal is genuinely fast — a food processor takes it from raw ingredients to finished sauce in about two minutes — so don’t skip it. It’s the thing that makes this burger taste complete rather than just filling.
Storage and reheating
Cooked patties keep in an airtight container in the fridge for up to 4 days. Store the sambal separately in a small jar — it keeps for 5 days refrigerated and actually gets a little better on day two once the flavors settle. To freeze, place cooked patties on a parchment-lined tray, freeze until solid (about 2 hours), then transfer to a freezer bag; they’ll keep for up to 2 months. Reheat patties in a dry skillet over medium heat for 3–4 minutes per side, or in a 350°F (175°C) oven for 10–12 minutes. The microwave works in a pinch but makes the exterior soft — the skillet keeps the crust intact. Don’t reheat the sambal; serve it straight from the fridge or at room temperature.
Common problems and fixes
- Patties fall apart when flipping: The mix is too wet or the patties didn’t rest. Pat the crumbled tempeh dry with a paper towel before mixing, and refrigerate the formed patties for at least 15 minutes before they hit the pan.
- Sambal tastes flat: Palm sugar varies a lot in sweetness depending on the brand. Taste the finished sambal and adjust — a little more lime juice sharpens it, a pinch more palm sugar rounds it out. It should have a clear sweet-sour-heat balance, not just heat.
- Patties are dense and dry in the center: Skip the egg in the mix — it makes the patty mushy on the outside while the inside stays tight and dry. The breadcrumbs alone are enough binder when the tempeh is crumbled fine.
- Coconut oil smokes before the patties are done: Coconut oil has a moderate smoke point. If your burner runs hot, cut the heat slightly and give the pan 30 extra seconds before adding the patties. A screaming-hot pan will char the outside before the center warms through.
- Burger bun goes soggy fast: Spread a thin layer of sambal on the top bun only right before serving, not during assembly. Putting sauce directly on the bottom bun soaks through quickly, especially if the patty is still steaming.

Ingredients
For the Tempeh Patties
- 400 g tempeh crumbled
- 2 tbsp soy sauce preferably low sodium
- 1 tbsp ground coriander
- 2 pieces shallots finely chopped
- 2 cloves garlic minced
- 1 small egg
- 50 g breadcrumbs preferably whole wheat
- 4 medium burger buns toasted
For the Sambal Sauce
- 3 pieces red chilies deseeded and chopped

Instructions
- In a large bowl, combine crumbled tempeh, soy sauce, ground coriander, chopped shallots, minced garlic, egg, and breadcrumbs. Mix until well blended. Form the mixture into 4 equal-sized patties.
- In a skillet, heat coconut oil over medium heat (about 170°C / 340°F). Cook the patties for approximately 4 minutes on each side, or until golden brown and firm to the touch.
- For the sambal sauce, blend red chilies, tomato, lime juice, and grated palm sugar in a food processor until a smooth paste forms.
- To assemble, place a tempeh patty on the bottom half of each toasted burger bun. Top with a generous spoonful of sambal sauce. Cover with the top half of the bun.

Common questions
Can I use store-bought sambal oelek instead of making the sambal from scratch?
Yes, sambal oelek works as a straight swap if you’re short on time. It won’t have the same fresh tomato body or the sweetness from palm sugar, so stir in a small squeeze of lime and a pinch of sugar to get closer to the homemade version.
Do I need to steam or pre-cook the tempeh before making the patties?
Not required, but steaming the tempeh block for 10 minutes before crumbling does reduce any residual bitterness that some brands carry. If your tempeh smells clean and mild straight from the package, skip the step and go directly to crumbling.
What can I substitute for palm sugar if I can’t find it?
Light brown sugar is the closest substitute — use the same amount. Coconut sugar also works well and is easier to find in most grocery stores. Avoid white sugar; it dissolves differently and the sambal ends up tasting sharper than it should.
How do I know when the tempeh patties are fully cooked through?
The patties are fully cooked when they’re deep golden brown on both sides and firm when you press the center lightly — there should be no give. Because tempeh is a fermented, fully processed ingredient rather than raw meat, you’re cooking for texture and crust rather than a specific internal temperature.
