Sambal oelek is a cooked chili paste made from fresh red chilies, garlic, vinegar, salt, and sugar — blended into a punchy condiment that keeps in the fridge for weeks. The honest reason to make it yourself is control: you pick the chili variety, decide how much heat you want, and end up with something fresher than anything in a jar. It takes 20 minutes and one saucepan.
The technique that matters
The simmer is doing real work here, not just softening the chilies. Cooking the chilies, garlic, vinegar, and sugar together for about 10 minutes drives off some of the raw sharpness and lets the flavors knit together before you blend. Don’t rush it or crank the heat — a hard boil will evaporate too much of the liquid and leave you with a paste that’s too thick and slightly bitter. Keep it at a gentle simmer until the chili skins look soft and the vinegar smell mellows, then pull it off the heat and let it cool for a few minutes before blending. Hot liquid in a blender can surge; a short rest prevents that.
Mistakes to avoid
- Skipping the cooling step before blending: Blending the mixture while it’s still very hot builds steam pressure inside the blender and can blow the lid off. Let it sit for 5 minutes first.
- Over-blending straight away: If you want any texture at all, pulse rather than run the blender continuously — once it’s fully smooth you can’t go back.
- Using a reactive pan: Aluminum reacts with vinegar and can give the sambal a metallic taste. Use stainless steel, enameled cast iron, or a non-stick saucepan.
- Not tasting before jarring: Salt and sugar levels shift slightly as the paste cools. Taste it at room temperature and adjust before sealing the jar — it’s much harder to fix once it’s stored.
- Storing in a plastic container: Chili paste stains plastic and can absorb off-flavors from it. A glass jar is the right call every time.
Shopping notes
Bird’s eye chilies are the go-to here — small, thin-skinned, and genuinely hot. Cayenne peppers work and are easier to find at most US grocery stores; they’re slightly milder but still deliver real heat. If you can only find Fresno or red jalapeño, the sambal will be noticeably milder and a bit fruitier, which isn’t bad but isn’t the same thing. Skip the pre-minced garlic in a jar — it has a fermented edge that clashes with the vinegar. Fresh cloves only. For the vinegar, plain distilled white vinegar is fine; the recipe doesn’t need anything fancy, and rice vinegar will make it noticeably sweeter.
Make-ahead notes
This is genuinely a make-ahead condiment. Stored in a sealed glass jar in the refrigerator, it keeps well for up to four weeks — the vinegar and salt do the preserving work. The flavor actually improves after a day or two as everything settles. For longer storage, freeze it in an ice cube tray, then transfer the frozen cubes to a zip-lock bag; individual cubes keep for up to three months and thaw in minutes at room temperature or straight into a hot pan. There’s no reheating needed — use it cold straight from the fridge or let a cube melt into whatever you’re cooking.
Indonesian Sambal Oelek
Ingredients
Ingredients
- 200 grams fresh red chilies Preferably bird’s eye or cayenne
- 4 cloves garlic Peeled and crushed
- 4 tablespoons white vinegar Use a high-quality white vinegar for best results
- 1 teaspoon salt Himalayan or sea salt preferred
- 2 tablespoons sugar Adjust to taste
Instructions
- Deseed the chilies for a milder sambal or leave the seeds in for maximum heat. Roughly chop the chilies.
- In a small saucepan over medium heat, add the chopped chilies, crushed garlic, white vinegar, salt, and sugar. Stir the mixture until the sugar has completely dissolved, bringing the mixture to a gentle simmer for about 10 minutes. You’re aiming for a fragrant aroma and softened chili skins.
- Allow the mixture to cool slightly, then transfer it to a blender or use an immersion blender to blend until you reach a smooth, paste-like consistency. If you prefer a chunkier texture, blend less thoroughly.
- Transfer the sambal oelek to sterilized glass jars. Seal tightly and store in the refrigerator for up to a month.

Your questions, answered
Can I use dried chilies instead of fresh?
Dried chilies will produce a noticeably different paste — earthier and less bright. If fresh aren’t available, rehydrate dried red chilies in hot water for 20 minutes, drain them, and proceed with the recipe, but expect a darker color and a smokier flavor rather than the clean heat of fresh.
How do I know how hot this will be before I commit?
Taste a small piece of one raw chili before you start — that tells you roughly what you’re working with. Removing all the seeds and white pith before cooking cuts the heat significantly, while leaving them in keeps it at full intensity.
Do I have to cook it, or can I just blend the raw ingredients?
You can blend everything raw, and some versions of sambal oelek are made that way, but the cooked version lasts much longer in the fridge and has a more rounded flavor. Raw sambal should be used within 3 to 4 days and tastes sharper and more pungent.
What burgers or sandwiches does this actually work on?
It works best anywhere you’d use sriracha or a spicy mayo — spread directly on the bun, stirred into mayo, or mixed into a ground chicken or beef patty before cooking. It’s especially good on Asian-style burgers with sesame, ginger, or soy in the mix.
