Toasted Sesame Sauce

This versatile vegetarian sauce starts with toasting a full cup of hulled sesame seeds in the oven until they turn golden and smell nutty. That toasting step concentrates the flavor dramatically. Combined with tahini, you’re getting a double hit of sesame that no store-bought sauce can match.

The seeds get ground fine in the blender before everything else goes in: water (or a milk substitute for extra creaminess), arrowroot for thickening, a bouillon cube for savory depth, tamari, and grated lemon zest. That lemon zest is doing important work here. It lifts the heaviness of all that sesame and keeps the sauce from tasting one-dimensional.

Arrowroot thickens the sauce as it heats without turning it gluey the way flour or cornstarch can. Stir frequently on medium-low and watch for it to shift from thin and pourable to a consistency that coats a spoon. It thickens further as it cools.

Pour this over steamed broccoli, roasted root vegetables, grain bowls, or toss it with hot pasta. It keeps in the fridge for up to a week and reheats easily with a splash of water to thin it back out.

Pro Tips

• Toast the seeds in a thin, even layer and stir them once or twice. They go from golden to burnt in seconds, so watch closely during the last few minutes.
• Grind the seeds in small batches (¼ cup at a time) for a finer, smoother result. Overloading the blender leaves chunky bits.
• Use tamari instead of soy sauce if you need this gluten-free. Same umami depth, no wheat.
• A pinch of cayenne goes a long way. Start small and add more after tasting.

Variations

• Stir in a tablespoon of miso paste for extra fermented richness.
• Add fresh grated ginger for a warmer, more Asian-inspired profile.
• Thin with coconut milk instead of water for a creamier, Thai-leaning version.
