Crab Louie Salad: The Classic West Coast Recipe with Authentic Louie Dressing

Crab Louie is one of the great American regional dishes — a composed salad of fresh crab, crisp vegetables, hard-boiled eggs, and a tangy, creamy dressing that has been served on the West Coast for over a century. James Beard described it as "the king of salads" in his 1964 cookbook Delights and Prejudices, and the description holds. This guide covers the authentic recipe, the history of the dish, and the technique details that make the dressing work.

A Brief History of Crab Louie

The origins of Crab Louie are disputed — the two most credible claims are Solari's Restaurant in San Francisco (where it appeared on the menu as early as 1914) and the St. Francis Hotel, also in San Francisco, where it was reportedly served at a banquet in the early 1900s. Seattle has also been proposed as the origin city. What is not disputed: the dish is a West Coast creation, built around Dungeness crab (the dominant commercial crab species of the Pacific Coast), and it reached national prominence in the 1910s–1920s when it appeared in cookbooks and restaurant guides across the country.

The "Louie" in the name is believed to refer to the dressing — a variation of Thousand Island or Russian dressing — rather than a specific person, though various chefs and restaurateurs have been credited with its invention over the years. The dressing is the defining element of the dish: without the Louie dressing, it is simply a crab salad.

Ingredients

Serves 4 as a main course

For the salad:

• 1 lb Dungeness crab meat, picked and checked for shell fragments, patted dry — or Dungeness merus meat for a premium presentation
• 4 cups romaine lettuce, chopped (or iceberg — the original used iceberg; romaine is more nutritious but iceberg provides a crisper texture)
• 2 large eggs, hard-boiled and sliced
• 1 ripe avocado, sliced
• 1 cup cherry tomatoes, halved (or 2 medium tomatoes, cut into wedges)
• 1 cucumber, thinly sliced
• 1/2 cup black olives, pitted and sliced
• 1/4 cup red onion, very thinly sliced
• Lemon wedges for garnish

For the Louie dressing:

• 1/2 cup good-quality mayonnaise (Kewpie preferred)
• 3 tbsp ketchup
• 2 tbsp sweet pickle relish
• 1 tbsp fresh lemon juice
• 1 tsp Worcestershire sauce
• 1 tsp prepared horseradish (adjust to taste; adds a pleasant sharpness)
• 1/4 tsp smoked paprika
• Salt and white pepper to taste

Method

Step 1: Make the Louie Dressing

Combine all dressing ingredients in a small bowl; whisk until smooth and uniform. Taste and adjust: more horseradish for sharpness, more lemon for brightness, more ketchup for sweetness. Refrigerate for at least 30 minutes before serving — this is not optional. The dressing needs resting time for the flavors to meld; a freshly made Louie dressing tastes sharp and disjointed; after 30 minutes it becomes cohesive and rounded. The dressing can be made up to 3 days in advance and stored in an airtight container in the refrigerator.

Step 2: Prepare the Salad Components

• Hard-boiled eggs: Place eggs in cold water; bring to a boil; reduce heat; simmer 10 minutes; transfer immediately to ice water for 5 minutes; peel and slice. The ice water stops cooking and prevents the gray ring around the yolk that indicates overcooking.
• Avocado: Slice immediately before assembling — avocado oxidizes quickly; if preparing in advance, toss slices with a small amount of lemon juice to slow browning.
• Red onion: If the raw onion flavor is too sharp, soak the sliced onion in cold water for 10 minutes; drain and pat dry — this removes the harsh sulfur compounds while preserving the onion's crunch and mild flavor.
• Crab meat: Pat dry with paper towels to remove excess moisture; keep in large chunks — do not shred.

Step 3: Assemble

Crab Louie is a composed salad — the components are arranged separately on the plate rather than tossed together. This is not just aesthetic; it allows each element to be tasted individually and in combination, and it prevents the vegetables from wilting in the dressing before serving.

1. Arrange chopped romaine on a large plate or shallow bowl as the base
2. Arrange cucumber slices, cherry tomatoes, avocado slices, hard-boiled egg slices, black olives, and red onion in separate sections around the perimeter of the plate
3. Place the crab meat in the center in large, visible chunks — the crab is the star; it should be the most prominent element on the plate
4. Drizzle a small amount of Louie dressing over the crab; serve the remaining dressing on the side
5. Garnish with lemon wedges

Serve immediately — once dressed, the salad should be eaten within 15–20 minutes before the lettuce wilts.

FAQs: Crab Louie Salad

What makes Crab Louie different from a regular crab salad, and what is the Louie dressing?

Crab Louie is a composed salad — the components (crab, vegetables, eggs) are arranged separately on the plate rather than tossed together, and it is served with a specific dressing called Louie dressing. The Louie dressing is the defining element: a creamy, tangy sauce made from mayonnaise, ketchup, sweet pickle relish, lemon juice, Worcestershire sauce, and horseradish — similar to Thousand Island or Russian dressing but with a more pronounced horseradish and Worcestershire character. Without the Louie dressing, it is simply a crab salad. The dressing must be made at least 30 minutes in advance — the flavors need resting time to meld; a freshly made Louie dressing tastes sharp and disjointed.

Is Crab Louie salad keto-friendly, and how do I reduce the carbs?

The salad itself (crab, lettuce, eggs, avocado, cucumber, tomatoes, olives) is naturally very low in carbohydrates. The carbs in the standard recipe come primarily from the Louie dressing: ketchup (~4g carbs per tbsp) and sweet pickle relish (~5g carbs per tbsp) are the main sources. The standard dressing recipe contains approximately 12–15g net carbs total for the full batch (4 servings), or approximately 3–4g net carbs per serving. To reduce further for strict keto: substitute sugar-free ketchup (reduces carbs by ~3g per tbsp); use dill relish instead of sweet pickle relish (reduces carbs by ~3g per tbsp); omit the relish entirely and add extra horseradish and a pinch of dill. The modified dressing contains approximately 1–2g net carbs per serving.

How far in advance can I prepare Crab Louie, and how do I store it?

The Louie dressing: up to 3 days in advance; store in an airtight container in the refrigerator; the flavor improves with time. The salad components: prepare up to 4–6 hours in advance and store separately in the refrigerator — lettuce (washed and dried, stored in a container lined with paper towels); hard-boiled eggs (peeled, stored in cold water); cucumber and tomatoes (sliced, stored in airtight containers); avocado (slice immediately before assembling — it browns quickly even with lemon juice). The crab meat: pat dry and store in an airtight container up to 2 days. Do not assemble the salad until immediately before serving — once dressed, the lettuce wilts within 15–20 minutes.
