In a mixing bowl, whisk together mayonnaise, ketchup, sour cream, lemon juice, vinegar, Worcestershire sauce, honey, smoked paprika, salt, and pepper. Mix well.
Chill the dressing in the fridge for at least an hour. Chilling is strongly recommended to allow the flavors to meld. Taste the dressing, and adjust seasonings to your preference (if needed)
For the Shrimp:
Heat oil in a skillet over medium heat. Add the shrimp to the skillet, season with salt, cajun seasoning (if using), and black pepper and sauté until it turns pink and cooked through, about 3-5 minutes depending on shrimp size. Do not overcook the shrimp. Remove onto a bowl.
Salad Assembly:
In a large salad bowl, lay out the chopped romaine lettuce.
Top with sautéed shrimp, cherry tomatoes, avocado slices, and hard-boiled eggs.
Sprinkle with capers. Serve with the chilled Louie dressing on the side or drizzled on top.
Notes
Choose your spice level: I used Slap Ya Mamma cajun seasoning, and it's quite spicy! Other cajun seasonings may be less spicy, or skip the seasoning and just use a bit of smoked paprika for no heat at all.
Be careful not to overcook the shrimp. Remove them from the skillet as soon as they are done, otherwise, they will continue to cook while you finish assembling the salad.
Chill the dressing. Try to plan ahead so that the dressing has at least an hour to chill in the fridge. The flavors are so much better this way!
If you need a shortcut, serve shrimp louie salad with your favorite bottled thousand island dressing. Although, the homemade dressing is so much more delicious!
Other ingredients to add to Shrimp Louie include crab meat, blanched asparagus or green beans, olives, red onion, or radishes.
Instead of shrimp, try this salad with poached chicken or poached salmon.
