Add all of the ingredients to a medium-sized bowl and whisk together until combined.
Transfer to a glass jar or dish, cover and store in the fridge until ready to use.
Notes
Finely grated parmesan. Make sure you finely grate your parmesan, using the smallest holes on your box grater. This helps the cheese blend into the dressing.
Amount of salt. I usually add ½ teaspoon, but since the parmesan is salty, start with ¼ teaspoon and add more to taste.
Garlic. You can use freshly minced or chopped jar garlic. Whatever is easiest for you! The amount of garlic depends on how garlicky you like your caesar dressing. We usually go with 3 cloves, but you can add 2 and then add more if you like.
Thin in out. This dressing is thick and creamy. If you prefer it thinner, just whisk in a little water until it reaches your desired consistency.
