Start by collecting all your ingredients. This makes the process smoother. Check your pantry to ensure you have what you need.
Toast the coriander and cumin seeds in a dry skillet over medium heat. Do this until they’re fragrant—about 2-3 minutes. This step intensifies the flavors.
In a blender or food processor, add the toasted seeds, chopped chilies, garlic cloves, cilantro, parsley, lemon zest, and lemon juice.
Slowly drizzle in the olive oil while blending the mixture. This creates a creamy, cohesive sauce. Make sure to scrape down the sides of the blender to capture all the beautiful herb mixture.
Taste your schug, and add salt, freshly cracked black pepper, or more lemon juice if desired. Adjust according to your preferences.
Give it one last blend just to mix the seasoning through thoroughly.
Enjoy your freshly made schug zhug sauce, or store it in an airtight container in the fridge.
