Seafood Salad Origins 1920S
While seafood salads had existed in various forms throughout history, the 1920s marked a significant shift in their popularity and preparation in America.
You’ll find that this era introduced new innovations in food preservation and refrigeration, making seafood more accessible across the country. During this time, you’d see tuna salad emerging as a staple in American households, thanks to the rising availability of canned fish.
The Jazz Age’s social gatherings and ladies’ luncheons helped popularize these lighter, protein-rich dishes.
You’d typically find these salads served at tea rooms and department store restaurants, where they’d often mix the seafood with celery, mayonnaise, and various seasonings. The practice of serving seafood salads in creative ways, such as in tomatoes or avocados, also gained traction during this period.

This quick and easy recipe requires minimal cooking skills and can be prepared in under 15 minutes. The combination of fresh ingredients creates a light yet filling meal that works well for lunch or as a quick dinner option, especially during warmer months when you want to avoid using the stove.
- 2 ripe avocados, halved and pitted
- 2 cans (5 oz each) tuna in water, drained
- 1/3 cup mayonnaise
- 1 celery stalk, finely diced
- 1/4 cup red onion, minced
- 2 tablespoons fresh lemon juice
- 1 tablespoon fresh dill, chopped
- 1 teaspoon Dijon mustard
- 1/4 teaspoon black pepper
- 1/4 teaspoon sea salt
- Optional: paprika for garnish
Slice the avocados in half and remove the pit. In a medium bowl, combine the drained tuna, mayonnaise, diced celery, minced red onion, lemon juice, dill, Dijon mustard, salt, and pepper. Mix well until all ingredients are thoroughly combined.
Scoop the tuna mixture into the avocado halves, dividing it equally among them. Sprinkle with paprika if desired and serve immediately.
For best results, choose avocados that yield slightly to gentle pressure but aren’t too soft. Greek yogurt can replace mayonnaise for a higher protein content, while red bell peppers can substitute celery for added color and crunch.
If preparing in advance, brush the avocado flesh with lemon juice to prevent browning, and store the tuna mixture separately until ready to serve.
