Step 1

Bring a large pot of salted water to a boil and cook pasta according to package instructions.

Step 2

Roughly chop the onion and add to a pan with the oil.

Step 3

Saute for about 5 minutes, then add in the garlic and continue to saute, about 2-3 more minutes.

Step 4

Add the onion/garlic mixture to a blender with all remaining ingredients and blend until smooth.

Step 5

Start with 2 cups of broth and add more as needed to reach your desired consistency, it will depend on the brand of tahini you used. It will also thicken when it heats up with the pasta, so keep that mind, you don't want it to start off too thick.

Step 6

Taste and adjust flavors as desired. Combine the sauce with the cooked pasta.

Step 7

You might have a bit of leftover sauce, depending on how saucy you like it (I always use it all), so it's perfect if you want to add any chicken or vegetables, or just save the extra sauce to use as a dip!

Step 8

Stir to combine and let simmer for a few minutes to allow the flavors to blend. Garnish with fresh basil and red pepper flakes. Enjoy!
