Eight simple ingredients for that signature Grimaldi’s zesty brightness in every bite.

The olive oil is non-negotiable here. California Olive Ranch or Colavita are my go-tos—look for dark glass bottles, not the stuff in clear plastic. Fresh lemon juice makes all the difference (bottled just doesn’t cut it). If you’re buying lemons specifically for this, Meyer lemons add a floral note that’s divine. The Dijon should be smooth, not that whole-grain stuff (unless you like texture).

No honey? Maple syrup or agave swaps in perfectly at a 1:1 ratio. Out of Dijon? Whole-grain mustard at half the amount works, but the flavor shifts. For garlic lovers, double the amount—it mellows out nicely. The oregano can be fresh if you’ve got it (use triple the amount). Skip the salt if your Dijon already has it.

This keeps beautifully in the fridge for 1 week. The flavors meld and mellow with time (it’ll taste better tomorrow). Shake or whisk before using—separation is natural. For longer storage, freeze in ice cube trays for up to 3 months.

Step-by-Step Instructions for Lemon Vinaigrette

Here’s my simple method for a bright, balanced dressing that comes together in minutes.

Step 1: Whisk Together the Acid Base

In a medium bowl, combine the 0.5 cup Fresh Lemon Juice with the 1 tbsp Dijon Mustard. I like to start with the acid because it helps emulsify the oil later. Whisk vigorously for 30 seconds until the mixture turns slightly pale and thickens.

This step is crucial—it creates a stable foundation that prevents separation. The Dijon mustard acts as a natural emulsifier, binding the oil and lemon juice together. You’ll see small bubbles form on the surface when it’s ready.

Step 2: Incorporate the Sweet and Aromatic Elements

Add the 1 tbsp Honey, minced 1 clove Garlic Clove, 0.5 tsp Kosher Salt, 0.25 tsp Freshly Ground Black Pepper, and 0.5 tsp Dried Oregano to the lemon-mustard mixture. Whisk again for another 20-30 seconds until everything is fully dissolved and combined.

The honey balances the acidity of the lemon, while the garlic and oregano add depth. I always press my garlic instead of mincing for a more intense flavor. Taste at this point—you should notice a bright, tangy base with hints of sweetness and herbaceousness.

Step 3: Slowly Emulsify the Olive Oil

Begin dripping in the 0.75 cup Extra-Virgin Olive Oil 1 tablespoon at a time, whisking constantly. This slow addition is what creates a stable emulsion. After adding about a quarter of the oil, you can start pouring in a thin, steady stream while continuing to whisk.

Watch the dressing transform—it should thicken and turn a pale, creamy yellow. If it starts to separate, don’t panic. Just stop adding oil and whisk vigorously for 10-15 seconds to bring it back together before continuing. The finished vinaigrette should coat the back of a spoon.

Step 4: Adjust and Finish

Give it one final whisk and taste. This is where you can fine-tune the flavors. If it’s too sharp, add another pinch of salt or a drizzle of honey. If it’s too thick, whisk in a teaspoon of warm water. The perfect balance should make your lips pucker slightly, then mellow into a smooth, well-rounded finish.

Let it sit for 5 minutes before using to allow the flavors to meld. The garlic will mellow slightly, and the oregano will infuse the oil. Store in an airtight jar in the refrigerator for up to 1 week—just give it a good shake before each use, as it may separate over time.

Troubleshooting Perfect Results

Separation Solutions

If your vinaigrette separates after sitting, don’t worry—this is completely normal. Simply whisk vigorously for 30-45 seconds or shake in a sealed jar until it re-emulsifies. The mustard will help it come back together quickly. 💡

Too Acidic Fix

Should your dressing taste too sharp or puckery, balance it with a touch more honey or maple syrup. Start with ½ tsp at a time, whisking well between additions until the brightness mellows into harmony.

Fixing a Broken Emulsion

If the oil and lemon completely separate and won’t reincorporate, start over with just the separated lemon-mustard mixture in a clean bowl. Slowly whisk in the oil again, 1 tsp at a time, until it re-emulsifies. Patience is key here.

Thickness Adjustments

For a thicker dressing, add the oil more slowly or use less oil overall. If it’s too thick, thin it with 1-2 tsp warm water or additional lemon juice. The ideal consistency should coat a spoon but still drizzle easily.

Garlic Overpowering

If the garlic flavor is too strong, let the dressing sit for 10-15 minutes before using. The acidity of the lemon will mellow the garlic’s bite naturally over time.

Storage Separation

When storing in the fridge, the dressing will naturally separate and the oil may solidify slightly. Just let it sit at room temperature for 5-10 minutes, then whisk or shake before using. 🍋
