Lemon Parmesan Mayonnaise Dressing

Introduction

This lemon Parmesan mayonnaise dressing combines bright citrus, sharp cheese, and creamy body into a versatile sauce that works equally well on salads, roasted vegetables, or as a dip. The dressing needs 8 hours or overnight to develop its flavors, so plan accordingly. You’ll have enough for 12 servings and can easily scale it down if you need less.

Recipe Details

• Prep Time: 10 minutes
• Cook Time: 0 minutes
• Total Time: 10 minutes (plus 8 hours chilling)
• Servings: 12

Ingredients

• 1 ½ lemons, juiced
• 1 cup freshly grated Parmesan cheese
• 2 teaspoons garlic salt
• ¾ cup mayonnaise
• 1 cup milk

Instructions

1. Mix together lemon juice, Parmesan cheese, garlic salt, and mayonnaise until smooth.
2. Stir in milk, adjusting the amount or adding a little water, to make the dressing as thin or thick as you like.
3. Cover and refrigerate 8 hours, or overnight.

Variations

Thinner consistency: Add an extra ¼ cup milk or water if you prefer a pourable dressing over a thick sauce.

Herb variation: Stir in 2 tablespoons of fresh chopped dill, parsley, or chives after the milk is incorporated for an herbed garden flavor.

Garlic boost: Replace the garlic salt with 1 teaspoon regular salt and 2 minced fresh garlic cloves for a sharper, fresher garlic note.

Anchovy variation: Mash 2–3 anchovy fillets into the mayonnaise before mixing in the other ingredients for a Caesar-style depth.

Reduced lemon: Use 1 lemon instead of 1 ½ if you find the citrus too dominant after the overnight chill.

Tips for Success

Juice your lemons fresh and strain out pulp or seeds before mixing to keep the dressing smooth and free of grit.

Freshly grated Parmesan melts into the dressing more evenly than pre-shredded; pre-shredded varieties contain anti-caking agents that can make the texture grainy.

Taste the dressing after it has chilled overnight—the lemon and cheese flavors intensify, so you may want to thin it with a little more milk or water at that point.

Let the dressing come to room temperature for 15 minutes before serving if it’s been refrigerated; cold dressing will taste duller and pour more slowly.

Storage and Reheating

Store the dressing in an airtight container in the refrigerator for up to 5 days. The dressing does not freeze well, as the emulsion breaks down when thawed. If it separates slightly after a few days, stir briskly or shake the container to recombine.

This dressing is served cold and requires no reheating. Simply stir before each use.

FAQ

Can I make this dressing ahead for a party?

Yes—in fact, you must make it at least 8 hours ahead. You can prepare it up to 5 days in advance, making it ideal for meal prep or entertaining.

What if my dressing breaks or looks grainy after chilling?

Grated Parmesan sometimes settles or the emulsion loosens slightly. Whisk it briskly or blend it in a food processor for 10 seconds to smooth it out. If it’s still grainy, strain it through a fine-mesh sieve.

Can I use bottled lemon juice instead of fresh?

Fresh lemon juice tastes brighter and more complex; bottled juice tends to taste flat and sulfurous in a cold dressing. If you must use bottled, use slightly less and taste as you go.

Is this dressing suitable for salads, or is it too thick?

It depends on how much milk you add in step 2. For salads, thin it toward the looser end of the range with extra milk or water. For dipping vegetables or as a sandwich spread, keep it thicker.
