Indonesian Chili Peanut Sauce

A quick Indonesian-style peanut sauce that works as a dip for satay skewers, a dressing for noodle bowls, or a glaze for grilled chicken. Garlic sautéed in oil, then peanut butter melted in with chicken broth, dark soy sauce, sesame oil, vinegar, and chili flakes.

Dark soy sauce (not regular) gives this sauce a deeper color and a slightly sweeter, more complex flavor than standard soy. It’s thicker and richer, and that matters in a sauce this simple. Dark Karo syrup adds body and a malty sweetness that rounds out the heat from the chili flakes.

Whisking constantly while heating is the key to a smooth sauce. Peanut butter wants to clump and separate when heated; the whisk keeps the emulsion stable and produces that silky, pourable consistency you’re after.

Kitchen Tips

• Sauté the garlic for just 30 seconds before adding the peanut butter. You want it fragrant, not brown. Burnt garlic makes the whole sauce bitter.
• Adjust the red pepper flakes to your heat tolerance. Start with a pinch and taste. You can always add more; you can’t take it back.
• The sauce thickens as it cools. If reheating, add a splash of broth or water to bring it back to the right consistency.
• The banana variation mentioned in the recipe is worth trying. Half a mashed ripe banana stirred in at the end adds creaminess and a subtle sweetness that balances the chili heat.

Variations

• Coconut peanut sauce: Replace the chicken broth with coconut milk for a richer, Thai-inspired version.
• Lime peanut sauce: Add fresh lime juice instead of vinegar and a teaspoon of lime zest for a brighter, more citrus-forward dipping sauce.
