This garlic-herb dip transforms fresh seafood with its bright, tangy flavor profile. A staple at coastal tables, it complements shrimp, crab, and oysters perfectly.
With just 5 ingredients and 10 minutes of prep, you’ll have a versatile sauce that elevates any seafood platter. The secret lies in balancing fresh herbs with a hint of acidity.
Ingredients for Boat Sauce
Eight ingredients create this bold, zesty seafood dip with minimal effort required.
| Ingredient | Amount | Notes |
|---|---|---|
| Mayonnaise 🥛 | 1 cup | Full-fat for creaminess |
| Prepared Horseradish 🌿 | 2 tbsp | Adjust to spice preference |
| Fresh Lemon Juice 🍋 | 2 tbsp | Newly squeezed for brightness |
| Worcestershire Sauce 🫒 | 1 tbsp | Adds umami depth |
| Garlic Cloves 🧄 | 2 cloves | Finely minced for even flavor |
| Fresh Dill 🌿 | 2 tbsp | Chopped, stems discarded |
| Dijon Mustard 🟡 | 1 tsp | Smooth variety preferred |
| Hot Sauce 🔥 | ½ tsp | Optional for extra heat |
The mayonnaise base is non-negotiable—Duke’s or Hellmann’s deliver the right richness and stability. For the horseradish, freshly grated offers superior punch, but prepared works in a pinch (look for Borden or Silver Spring brands). The lemon juice must be fresh—bottled lacks the bright acidity this sauce demands. Whole Foods and Harris Teeter typically carry all ingredients year-round.
No fresh dill? Dried dill at one-third the amount works, though the flavor is more concentrated. Out of Worcestershire? Soy sauce with a pinch of sugar can substitute, but the depth won’t be identical. For a lighter version, Greek yogurt can replace half the mayo—just strain it first to avoid a watery dip. The garlic can be granulated at half the quantity if fresh isn’t available.
This keeps 1 week refrigerated in an airtight container. The flavors meld and intensify over 24 hours, so make it a day ahead if possible. Not suitable for freezing—mayonnaise separates when thawed.

Step-by-Step Instructions for Boat Sauce
This method ensures a perfectly balanced dip with vibrant flavors and smooth texture.
Step 1: Prepare the Garlic and Fresh Ingredients
Finely mince the 2 cloves Garlic Cloves until you achieve a near-paste consistency. This fine texture ensures even distribution throughout the sauce without overpowering any single bite.
Chop the 2 tbsp Fresh Dill, discarding the stems as they can be bitter. The dill should be finely minced as well to blend seamlessly with the other ingredients.
Step 2: Combine the Wet Components
In a medium mixing bowl, add the 1 cup Mayonnaise as your base. Full-fat mayonnaise creates the creamy foundation that carries all the bold flavors in this sauce.
Whisk in the 2 tbsp Fresh Lemon Juice, 1 tbsp Worcestershire Sauce, and 1 tsp Dijon Mustard until fully incorporated. The lemon juice adds brightness, while the Worcestershire contributes umami depth and the mustard provides subtle tang.
Step 3: Incorporate the Bold Flavors
Add the minced 2 cloves Garlic Cloves and 2 tbsp Prepared Horseradish to the mixture. The horseradish brings a sharp, spicy kick that defines this sauce, while the garlic adds aromatic complexity.
For those who prefer extra heat, stir in the 0.5 tsp Hot Sauce. This amount provides a gentle warmth without overwhelming the other flavors. Adjust this to taste if you’ve prepared additional sauce.
Step 4: Finish and Rest the Sauce
Fold in the chopped 2 tbsp Fresh Dill until evenly distributed throughout the mixture. The dill’s fresh, grassy notes complement the rich, tangy elements perfectly.
Cover the bowl and refrigerate for at least 30 minutes to allow the flavors to meld. This resting period is crucial for the garlic to mellow slightly and for all components to harmonize into the signature zesty profile.
Give the sauce a final stir before serving. The texture should be smooth with visible flecks of dill, and the color will be a pale cream with green specks. Serve chilled alongside your favorite seafood.
Pro Tips For Making Boat Sauce
- Grate Fresh Garlic: Skip the pre-minced stuff—freshly grated garlic cloves release more flavor and blend smoother into the mayo base.
- Balance the Horseradish: Start with half the prepared horseradish you think you need, taste, then add more. It intensifies as the sauce sits.
- Rest Before Serving: Let the sauce sit for at least 30 minutes after mixing. The flavors meld better, and the garlic mellows out.
- Use Full-Fat Mayo: I learned this the hard way—light mayo makes the sauce thin and watery. Full-fat holds up to the lemon and horseradish.
Perfect Pairings for These Flavors
Seafood Pairings
This dip shines with steamed shrimp—the creamy sauce clings perfectly to each piece. Try it with 1 lb peeled shrimp for a classic combo. I also love it with crab cakes or oysters on the half shell, where its bold flavors cut through the richness. 🦞
Grilled Favorites
Spread it on grilled salmon fillets or use as a topping for blackened mahi-mahi. The tangy kick balances the smoky char beautifully. For a quick meal, brush it on scallops before grilling—they’ll caramelize with extra flavor.
Crudité Platter
Serve with celery sticks, cucumber slices, or bell pepper strips for a lighter option. The sauce adds a zesty punch to fresh veggies. I always include endive leaves for a crisp, slightly bitter contrast.
Beverage Matches
A crisp Sauvignon Blanc or Pilsner beer pairs wonderfully, cutting through the creaminess. For non-alcoholic options, sparkling water with lime refreshes the palate. The acidity mirrors the sauce’s bright notes. 🍺
Creative Uses
Use it as a seafood salad dressing for crab or lobster rolls. Toss with cold shrimp and avocado chunks for a quick ceviche-style dish. It even works as a fish taco sauce with added lime zest.

Frequently Asked Questions
Can I make this ahead of time?
Yes, it tastes even better after 24 hours in the fridge. This gives the flavors time to meld together. Just store it in an airtight container for up to 1 week.
What if I don’t like spicy flavors?
Simply omit the horseradish and hot sauce. You’ll still get a creamy, herby sauce with bright lemon notes. For milder heat, reduce horseradish to 1 tablespoon.
Can I use dried herbs instead of fresh?
Yes, use 2 teaspoons dried dill for every 2 tablespoons fresh. Dried herbs are more concentrated, so adjust accordingly for best results.
Why does my sauce look separated?
This usually happens if ingredients weren’t fully mixed or if stored too long. A quick whisk before serving restores its creamy texture. Always use full-fat mayo for stability.
