Step 1: Combine Mayonnaise and Parmesan: In a medium-sized bowl, combine the mayonnaise and grated Parmesan cheese. Ensure the Parmesan is finely grated for a smoother dressing. Stir until well combined, creating a creamy base.
Step 2: Add Garlic, Lemon Juice, and Olive Oil: Add the minced garlic, fresh lemon juice, and olive oil to the bowl. The fresh lemon juice is critical for the bright flavor. Stir well to incorporate these ingredients, ensuring even distribution of the garlic throughout the mixture.
Step 3: Incorporate Dijon Mustard and Pepper: Add the Dijon mustard and freshly ground black pepper. The Dijon mustard contributes a subtle tang, complementing the other flavors. Grind fresh black pepper for the best aroma and flavor. Stir until all ingredients are fully incorporated.
Step 4: Season with Salt and Adjust Consistency (Optional): Season the dressing with salt, starting with a small amount and adjusting to taste. If the dressing is too thick, add water, one tablespoon at a time, until it reaches the desired consistency. Stir well after each addition of water.
Step 5: Chill and Serve: Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to allow the flavors to meld. This chilling period enhances the overall taste of the dressing. Serve over crisp romaine lettuce with croutons and Parmesan shavings for a classic Caesar salad.
Optional Tips: For a richer flavor, add 1-2 anchovy fillets, finely minced, to the dressing. For a vegan version, substitute the mayonnaise with a vegan mayonnaise alternative and nutritional yeast for Parmesan cheese. Adjust the amount of lemon juice and garlic to suit individual taste preferences. This dressing can be stored in an airtight container in the refrigerator for up to 3 days.
