Prepare Fresh Herbs: Roughly chop the fresh parsley and dill to make blending easier. There is no need for precision here, as they will be going into the food processor or blender.
Blend Tahini Base with Flavors: In your food processor or blender, combine the tahini, lemon juice, Dijon mustard, nutritional yeast, and garlic powder. Blend these together until they form a smooth, well-combined base. The Dijon mustard will add a tangy depth, while the nutritional yeast contributes a cheesy umami flavor.
Add Herbs and Sweetness: To the mixture in your food processor or blender, add the chopped fresh parsley, dill, and maple syrup. The fresh herbs will bring a vibrant freshness to the sauce, and the maple syrup adds a touch of natural sweetness that balances the acidity of the lemon juice.
Adjust Consistency: Begin by adding 1/4 cup of water to the mixture. Blend until smooth and check the consistency. If you prefer a thinner sauce, gradually add more water (up to 1/2 cup in total), blending after each addition until you reach your desired thickness.
Season to Taste: Season the sauce with salt and pepper. It's best to start with a small amount, blend, taste, and then adjust as necessary.
Final Blend: Once you've adjusted the seasoning to your liking, give the sauce one last blend to ensure everything is thoroughly combined and the sauce is smooth.
Serve or Store: Your Vegan Lemon Herb Tahini Sauce is now ready to elevate salads and bowls or even serve as a splendid dip for veggies and crackers. If not using immediately, store the sauce in an airtight container in the refrigerator.
