Ingredients

4 fillets salmon fillets Choose fresh, high-quality fillets for best flavor.
2 tablespoons Cajun seasoning Adjust to your preferred spice level.
4 buns soft sandwich buns Brioche or potato buns work wonderfully.
1 tablespoon olive oil Use a high-smoke point olive oil for searing.
1 cup shredded lettuce Crisp romaine or iceberg lettuce is ideal.
1 tomato tomato Use a ripe, firm tomato, thinly sliced.
0.5 red onion red onion For a milder flavor, soak slices in ice water for 10 minutes.
0.25 cup mayonnaise Full-fat mayonnaise provides the best creaminess.
1 tablespoon lemon juice Freshly squeezed lemon juice is highly recommended.
0.5 tsp Salt Season generously to enhance flavors.
0.25 tsp pepper Freshly ground black pepper adds a nice kick.

Method

Heat a cast-iron skillet over medium-high heat until it’s smoking hot.
Generously sprinkle the Cajun seasoning, salt, and pepper over the salmon fillets.
Add the olive oil to the skillet and place the seasoned salmon fillets skin-side down. Cook for about 4-5 minutes.
In a small bowl, whisk together the mayonnaise and lemon juice.
Lightly toast your sandwich buns in the skillet or toaster.
Spread the creamy sauce on the bun, place the salmon, and top with lettuce, tomato, and onion.
Pair with chips or salad for a complete meal.
