This velvety sauce transforms any seafood dish into a restaurant-quality experience. I developed this recipe to capture that perfect balance of creamy richness and delicate seafood flavor.
With just a few simple ingredients and 10 minutes of prep, you’ll have a smooth, flavorful sauce that elevates crab, shrimp, or even fries to new heights.
Ingredients for Crab Du Jour Sauce
Ten ingredients transform into this creamy, restaurant-quality seafood dipping sauce with ease.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥚 | 1 cup | Full-fat for creaminess |
| Sour Cream 🥛 | ½ cup | Full-fat preferred |
| Lemon Juice 🍋 | 2 tbsp | Freshly squeezed preferred |
| Prepared Horseradish 🌿 | 1 ½ tbsp | Adjust for heat preference |
| Worcestershire Sauce 💧 | 1 tbsp | Anchovy-based for depth |
| Dijon Mustard 🟡 | 1 tbsp | Smooth, not whole grain |
| Garlic Cloves 🧄 | 2 cloves | Finely minced |
| Cayenne Pepper 🔥 | ¼ tsp | Optional for heat |
| Old Bay Seasoning 🌶️ | ½ tsp | Classic seafood blend |
| Hot Sauce 🌶️ | ½ tsp | Such as Crystal or Tabasco |
The mayonnaise is the foundation—Duke’s or Hellmann’s give that classic creamy base. Sour cream adds tang, so don’t skip the full-fat version (trust me on this). For the horseradish, Bubbies brand is my go-to for consistent heat. The Worcestershire is non-negotiable; Lea & Perrins has the right anchovy depth. Fresh lemon juice brightens everything, so skip the bottled stuff.
No horseradish? Fresh grated ginger at half the amount gives a similar kick. Out of Old Bay? Celery salt plus paprika (equal parts) works in a pinch. For extra richness, swap one-quarter of the mayo for crème fraîche. The hot sauce is flexible—use whatever’s in your fridge. If you’re avoiding anchovies, vegetarian Worcestershire exists but won’t deliver the same seafood depth.
This sauce keeps 1 week in the fridge, covered tightly. The flavors meld after a day, so make it ahead if possible. Not freezer-friendly—the mayo separates. Stir well before serving, and thin with a splash of water if needed.

Step-by-Step Instructions for Crab Du Jour Sauce
This refined method ensures a perfectly balanced, restaurant-quality sauce with minimal effort.
Step 1: Combine the Creamy Base
In a medium mixing bowl, whisk together the 1 cup Mayonnaise and 0.5 cup Sour Cream until completely smooth and homogeneous. The full-fat versions are essential here—they provide the velvety texture that defines this sauce.
This step establishes the rich foundation. I always use a whisk rather than a spoon to incorporate air, which lightens the mixture slightly without compromising its luxurious mouthfeel.
Step 2: Incorporate the Acidic and Pungent Elements
Add the 2 tbsp Lemon Juice, 1.5 tbsp Prepared Horseradish, 1 tbsp Worcestershire Sauce, and 1 tbsp Dijon Mustard to the bowl. Whisk vigorously to fully emulsify these ingredients into the creamy base.
The lemon juice brightens the flavor profile, while the horseradish adds its characteristic bite. The Worcestershire contributes umami depth, and the Dijon mustard lends a subtle tang and slight thickness.
Step 3: Introduce the Aromatic and Spicy Components
Press the 2 cloves Garlic Cloves through a garlic press directly into the mixture, then add the 0.25 tsp Cayenne Pepper, 0.5 tsp Old Bay Seasoning, and 0.5 tsp Hot Sauce. Whisk until all ingredients are uniformly distributed.
The finely minced garlic should be fully incorporated—no visible chunks. The Old Bay Seasoning brings its signature blend of celery salt, paprika, and other spices that complement seafood beautifully. The cayenne and hot sauce provide a gentle heat that balances the richness.
Step 4: Chill and Allow Flavors to Marry
Cover the bowl with plastic wrap and refrigerate for at least 1 hour. This resting period is crucial—it allows the flavors to meld and the sauce to achieve its optimal consistency.
I recommend transferring the sauce to an airtight container if storing longer than 2 hours. The flavors will continue to develop over time, reaching peak harmony after about 24 hours in the refrigerator.
Stir well before serving to redistribute any separated elements. The finished sauce should coat the back of a spoon thickly while still being pourable.
Pro Tips For Making Crab Du Jour Sauce
- Chill the Base: Let the mayonnaise and sour cream sit in the fridge for 30 minutes before mixing—this keeps the sauce from separating when you fold in the horseradish. I learned this the hard way after my first batch looked like curdled milk.
- Zest Before Juicing: Add a teaspoon of lemon zest along with the juice for a brighter, more complex flavor. Sounds weird, but it works: the zest’s oils make the sauce taste fresher than lemon juice alone.
- Mind the Horseradish: Start with 1 tablespoon of prepared horseradish, taste, then add more—it’s easy to overdo it and end up with a sauce that’s all heat and no balance. My grandmother swore by this, and she was right.
- Thin Gradually: If the sauce is too thick, thin it with a splash of cold water or lemon juice, not more mayo. After burning three batches by making them too runny, I finally figured out that less is more.
Troubleshooting This Dish
Sauce Too Thin
If your sauce is runny after chilling, you likely overmixed or used low-fat dairy. Fix this by whisking in an additional 2 tbsp mayonnaise or 1 tbsp sour cream. Let it rest for 30 minutes to thicken. 💡
Sauce Separated
Separation happens when ingredients aren’t fully emulsified. Rescue it by whisking vigorously for 1-2 minutes until smooth. If stubborn, stream in 1 tsp cold water while whisking to rebind the mixture.
Too Much Heat
Overdid the horseradish or cayenne? Balance the spice with 1-2 tbsp additional mayonnaise or a squeeze of lemon juice. The acid and creaminess will mellow the burn without diluting flavor.
Bland Flavor
Needs more punch? Add ½ tsp Worcestershire or ¼ tsp Old Bay and let sit for 15 minutes. Taste and adjust—sometimes it just needs time for flavors to bloom.
Lumpy Texture
Lumps often come from horseradish or garlic clumps. Press the sauce through a fine-mesh strainer or blend briefly with an immersion blender. For garlic, always press—not mince—through a garlic press.
Sauce Too Thick
Thin with 1 tsp water or lemon juice at a time, whisking between additions. This maintains flavor while achieving your desired consistency. Remember, it thickens slightly when chilled. ✨

Frequently Asked Questions
Can I make this sauce ahead of time?
Yes! The flavors actually improve after 24 hours in the fridge. Store in an airtight container for up to 1 week.
What can I use instead of horseradish?
Try ½ tsp fresh grated ginger for a milder kick. Or use 1 tbsp prepared wasabi for a different heat profile. Both work well with seafood.
Why does my sauce taste flat?
It might need more Worcestershire or Old Bay. Start with ½ tsp of either, then adjust. Let it sit for 15 minutes before retasting.
Is there a lighter version?
Swap half the mayo for Greek yogurt, but note the texture will be slightly thinner. Full-fat dairy still gives the best results.
