The shrimp is the foundation here. Costco’s frozen cooked shrimp (16/20 count) thaws beautifully—just run under cold water in a colander. Look for wild-caught if available, though farmed is fine for this dish. The celery and red onion add essential crunch, so choose firm stalks and onions with vibrant color. Fresh dill from the produce section beats dried every time (the feathery kind, not the seed).

No fresh dill? Dried dill at one-third the amount works in a pinch, though the flavor is more concentrated. Out of mayonnaise? Greek yogurt (full-fat for creaminess) is a lighter alternative. No Dijon? Yellow mustard plus a pinch of turmeric gets you close. The lemon-dill combo is classic, but tarragon or parsley can sub for the dill if that’s what’s growing in your garden.

This keeps 2 days in the fridge—perfect for making ahead. The flavors meld beautifully overnight. Serve on butter lettuce or with crackers, but don’t assemble until ready to eat (the lettuce wilts). Leftovers? Toss with cold pasta for a quick second meal.

Step-by-Step Instructions for Shrimp Salad

This method ensures bright, creamy results with minimal effort and maximum flavor.

Step 1: Prepare the Shrimp and Aromatics

Thaw the 1.5 lb Cooked Shrimp if frozen, then drain and pat dry with paper towels. This removes excess moisture that could thin the dressing. Transfer to a large mixing bowl and set aside.

Finely mince the 2 cloves Garlic Cloves and the 0.25 cup Red Onion—this fine texture ensures even distribution throughout the salad. The onion’s sharpness will mellow as it sits with the dressing.

Step 2: Mix the Creamy Lemon-Dill Dressing

In a medium bowl, whisk together the 0.75 cup Mayonnaise, 3 tbsp Lemon Juice, 1 tbsp Lemon Zest, 1 tbsp Dijon Mustard, minced garlic, 1 tsp Salt, and 0.5 tsp Black Pepper until smooth. The acidity from the lemon will balance the richness of the mayonnaise.

Stir in the 0.25 cup Fresh Dill last—this preserves its bright green color and delicate flavor. The dressing should be thick but pourable. If it seems too stiff, let it sit for 2-3 minutes to loosen slightly before combining.

Step 3: Combine Vegetables and Shrimp

Add the 1 cup Celery and minced red onion to the bowl with the shrimp. Pour the dressing over the top and fold everything together gently with a silicone spatula. You want to coat every piece without breaking up the shrimp.

Let the mixture sit for 10 minutes to allow the flavors to meld. The celery will soften slightly, and the shrimp will absorb the zesty dressing. Taste and adjust seasoning if needed—sometimes a pinch more salt brings out the flavors.

Step 4: Chill and Serve

Cover the bowl and refrigerate for at least 30 minutes (or up to 2 hours). This chilling step is crucial—it lets the flavors deepen and the salad thicken slightly. The shrimp will plump up as it absorbs the dressing.

Serve the salad chilled on a bed of Butter Leaf Lettuce leaves or with Crackers on the side. The lettuce adds a crisp contrast, while crackers make it easy to scoop up every creamy, tangy bite. For best texture, avoid overmixing just before serving.

Essential Equipment for Perfect Results

Mixing Bowls

I always reach for my stainless steel mixing bowls—they’re durable, non-reactive, and the 1.5 quart size is perfect for this recipe. A set from Cuisinox stays in my kitchen for everything from dressings to marinades. The weight feels just right when folding the ingredients together. 💛

Whisking Tools

A balloon whisk is essential for emulsifying the dressing smoothly. My OXO Good Grips 11-inch whisk blends the mayonnaise and lemon juice without creating air bubbles. The comfortable handle makes it easy to get into the corners of the bowl.

Cutting Essentials

For the celery and onion, a sharp chef’s knife is non-negotiable. I use an 8-inch Wüsthof with a fine edge. A cutting board with a groove catches juices and keeps my counter clean while dicing the 1 cup celery and 0.25 cup red onion.

Measuring Accuracy

Precision matters, especially with the 3 tbsp lemon juice and 1 tbsp Dijon mustard. My stainless steel measuring spoons from RSVP Endurance nest together neatly and resist rust. For the 0.75 cup mayonnaise, a liquid measuring cup ensures the right volume.

Chilling Solution

An airtight glass container is ideal for refrigerating the salad. I prefer Pyrex Simply Store with snap-on lids—they’re leakproof and stackable. The 30-minute chill works best in a shallow, wide container so the flavors meld evenly. ❄️

Serving Style

For presentation, a slotted spoon helps drain excess dressing when serving on butter leaf lettuce. I also keep a wooden serving board handy for a rustic touch. The salad looks stunning on my hand-thrown ceramic platter for gatherings.
