Yes, you can use store-bought Caesar dressing! It's very convenient and saves time. If you prefer a fresher taste or want to control the ingredients and seasoning, making your own Caesar salad dressing from scratch is also an excellent option. Homemade Caesar dressing typically includes ingredients like garlic, anchovy paste (or Worcestershire sauce as a substitute), Dijon mustard, lemon juice, mayonnaise, olive oil, and Parmesan cheese.
