Gather all your ingredients for the Garlic Parmesan Sauce, including freshly grated Parmesan cheese, mayonnaise, crushed garlic cloves, Italian seasoning, lemon juice, olive oil, salt, and black pepper.

In your food processor, add the grated Parmesan cheese, mayonnaise, crushed garlic cloves, Italian seasoning, and fresh lemon juice. Drizzle in the olive oil.

Blend the mixture on high speed for about 30 seconds until the sauce reaches a velvety consistency.

Taste the sauce and add salt and black pepper as needed, blending again for about 10 seconds to integrate.

Transfer the sauce into an airtight container and refrigerate for at least 30 minutes to allow flavors to meld.

Once the sauce has rested, give it a gentle stir and use it as desired.
