Gather all your ingredients: grated Parmesan cheese, mayonnaise, crushed garlic, Italian seasoning, lemon juice, olive oil, salt, and black pepper.

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

Blend the mixture for about 30 seconds to a minute until smooth and creamy; scrape down the sides with a spatula as needed.

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

After chilling, stir the sauce and serve as a dip or toss with your favorite warm pasta.
