Swapping tahini for the mayonnaise that you typically see in classic Caesar salads keeps things creamy but adds nutty earthiness to the tangy mustard and funk from Parmesan cheese.
Step 1
Mound anchovies and garlic on a cutting board. Using the side of a chef’s knife, mash together until a smooth paste forms.
Step 2
Transfer paste to a large bowl and squeeze in juice from 1 lemon half (about 2 Tbsp.). Whisk in tahini, mustard, and 2 Tbsp. water. Gradually whisk in oil until dressing is thick and glossy. Whisk in 3 Tbsp. Parmesan; season with salt and pepper.
