This incredibly fast and easy Thai peanut sauce comes together in just five minutes with a bowl and a whisk. Creamy peanut butter, tangy lime, and a hint of chili create a perfectly balanced, versatile sauce that works as a dip, dressing, marinade, or stir-fry sauce. It's a homemade secret weapon that transforms simple ingredients into something spectacular.
For best results, let peanut butter sit at room temperature for 10 minutes before starting to ensure smooth whisking. Store leftover sauce in an airtight container in the refrigerator for up to one week; it will thicken when chilled, so stir in a little warm water before using. Variations: For a nut-free version, substitute sunflower seed butter or tahini. For extra richness, replace the water with 2 tablespoons of full-fat coconut milk. Add 1 teaspoon toasted sesame oil for a nutty aroma, or fold in fresh cilantro or Thai basil just before serving.
