Seafood Salad Recipe Without Mayonnaise: Lemon-Dill Brightness With Ocean Flavors

This seafood salad delivers ocean-fresh flavors without relying on mayonnaise for creaminess. The secret lies in a bright lemon-dill dressing that enhances rather than masks the natural taste of the seafood.

I’ve perfected this recipe by using a light olive oil base with fresh lemon juice, chopped dill, and a touch of Dijon mustard for depth. It keeps the salad light and refreshing while ensuring every bite is packed with flavor.

The combination of tender seafood, crisp vegetables, and that zesty dressing creates a dish that’s both elegant and approachable. It’s perfect for summer gatherings or a quick, nutritious lunch.

Serve chilled for the best experience. This salad holds up well in the fridge for a day or two.

Ingredients for Seafood Salad Recipe Without Mayonnaise

Fresh seafood and crisp vegetables meet a zesty lemon-dill dressing for bright, elegant flavors.

The seafood is the star here. Wild-caught shrimp and scallops from Whole Foods or a trusted fishmonger ensure the best flavor and texture. Look for shrimp labeled as ‘easy peel’ to save time, and opt for dry-packed scallops (not wet-packed) to avoid excess moisture. Freshness is key—seafood should smell clean and briny, never fishy. If using frozen, thaw overnight in the fridge (never at room temperature).

No shrimp? Lump crabmeat or cooked lobster work beautifully (adjust quantities to match the shrimp weight). Swap scallops for chopped clams or mussels. For a fully plant-based twist, try marinated artichoke hearts or hearts of palm. The dill can be replaced with tarragon or basil, but reduce by half—they’re more potent. If using bottled lemon juice, add a splash of vinegar to brighten the flavor.

This salad stays fresh for 2 days in the fridge—store it in an airtight container with a paper towel on top to absorb excess moisture. The flavors meld and improve after a few hours, so make it ahead if possible. Not suitable for freezing, as the seafood texture will degrade.

Step-by-Step Instructions for Seafood Salad Without Mayonnaise

Here is the method. Straightforward, tested, works every time.

Step 1: Prepare and Chop All Vegetables

Start by dicing the 1 whole Cucumber into ¼-inch pieces. I prefer English or Persian varieties as they have fewer seeds and thinner skin. Next, thinly slice the 4 whole Radishes—a mandoline works well for consistent thickness.

Finely chop the 2 pieces Celery stalks and finely dice the 0.25 whole Red Onion. The onion should be cut small enough to distribute evenly without overpowering any single bite. Place all chopped vegetables in a large mixing bowl.

Step 2: Combine the Dressing Ingredients

In a small bowl, whisk together the 0.33 cup Fresh Lemon Juice and 1 tbsp Dijon Mustard until smooth. Slowly drizzle in the 0.33 cup Extra-Virgin Olive Oil while continuing to whisk—this creates a temporary emulsion for a creamy texture without mayo.

Add the 1 tbsp Lemon Zest, 0.5 tsp Salt, and 0.25 tsp Black Pepper to the dressing. Whisk again to fully incorporate all ingredients. The dressing should have a bright, tangy aroma from the lemon and a slight sharpness from the mustard.

Step 3: Incorporate Seafood and Fresh Herbs

Add the 1 lb Cooked Shrimp and 0.5 lb Cooked Scallops to the bowl with the chopped vegetables. If using bay scallops, you may want to halve them for more even distribution. Pour the dressing over the seafood and vegetables.

Sprinkle the 0.5 cup Fresh Dill and 0.25 cup Fresh Parsley over the top. Both herbs should be chopped just before adding to preserve their fresh flavor. The dill will provide a bright, slightly grassy note that pairs perfectly with the seafood.

Step 4: Toss and Chill for Optimal Flavor

Using a large spoon or salad tongs, gently toss all ingredients until evenly coated with the dressing. Be careful not to break up the shrimp and scallops too much—you want visible pieces of seafood in every bite.

Cover the bowl and refrigerate for at least 30 minutes before serving. This chilling time allows the flavors to meld together and lets the vegetables absorb some of the dressing. The salad can be made up to 2 hours ahead for best results.

Step 5: Serve and Enjoy

Give the salad one final gentle toss before serving. The colors should be vibrant—pink shrimp, white scallops, green herbs, and the various vegetable hues. Taste and adjust seasoning if needed, though the dressing should provide ample flavor.

Serve chilled in bowls or on a platter lined with lettuce leaves. This dish works well as a light main course or as part of a seafood spread. The absence of mayonnaise means it will keep well in the refrigerator for up to 2 days without separating or spoiling.

Creative Variations of This Dish

Mediterranean Style

Swap the dill for 1/4 cup chopped fresh mint and add 1/2 cup crumbled feta cheese. I also love including 1/2 cup Kalamata olives for a briny punch. The lemon-dill dressing works beautifully with these Mediterranean flavors. 🌿

Asian-Inspired Twist

Replace the lemon-dill dressing with a ginger-lime vinaigrette: whisk 1/4 cup lime juice with 1 tbsp grated ginger, 2 tbsp soy sauce, and 1 tbsp honey. Add 1/2 cup edamame and 1/4 cup chopped cilantro for freshness.

Spicy Cajun Version

Toss the seafood with 1 tbsp Cajun seasoning before adding to the salad. I use Tony Chachere’s for authentic flavor. Add 1 diced avocado and 1 minced jalapeño for creaminess and heat. The lemon-dill dressing balances the spice perfectly. 🔥

Citrus Fruit Addition

Add 1 cup segmented grapefruit or orange supremes for a sweet-tart contrast. The citrus pairs wonderfully with the shrimp and scallops. I prefer ruby red grapefruit for its vibrant color and slightly bitter edge.

Herb-Focused Variation

Create an herb garden version with 1/4 cup each chopped tarragon, chives, and basil instead of just dill. This trio adds complexity while keeping the dish light. I often add 1 tbsp capers for a salty, briny note.

Creamy Avocado Dressing

Blend 1 ripe avocado with the lemon juice, 2 tbsp Greek yogurt, and 1 garlic clove for a creamy, mayo-free dressing. This version is rich yet still fresh. The avocado adds healthy fats and a velvety texture.
