Ingredients
Method
Make the dressing
- Whisk the mayonnaise, sour cream, lemon juice, Dijon, Worcestershire, anchovy paste, garlic, Parmesan, and black pepper until combined, then whisk in the water.
Cook the pasta
- Bring the 4 quarts water and kosher salt to a boil in an 8-quart pot.
- Add the rotini and cook according to the package directions, usually 8–10 minutes, until al dente.
- Drain the pasta, rinse under cold water until cool, and drain thoroughly.
Assemble the salad
- Toss the pasta with about three-quarters of the dressing in a large bowl, cover, and refrigerate for 20–30 minutes.
- Just before serving, toss with the romaine, croutons, and remaining dressing.
Notes
For the best texture, add the romaine and croutons just before serving. Refrigerate leftovers in an airtight container for up to 2 days; freezing is not recommended. For a gluten-free version, use gluten-free rotini and croutons.
