Cook the pasta according to package instructions until al dente. Reserve about 1/2 cup of pasta water, then drain the pasta.
In a large mixing bowl, combine tahini, olive oil, minced garlic, lemon juice, salt, and black pepper.
Whisk the ingredients together until you achieve a smooth and creamy consistency.
If the tahini sauce is too thick, gradually add the reserved pasta water, a tablespoon at a time, until it reaches your desired thickness.
Add the cooked and drained pasta to the tahini sauce, tossing to coat the pasta evenly.
Garnish with red pepper flakes and chopped parsley, if desired.
Serve the Easy Tahini Pasta warm, savoring the nutty richness of tahini combined with the zesty notes of lemon for a simple yet satisfying pasta dish. Enjoy!
