Start by preheating your smoker or grill to medium-high heat. Place the smoked tuna on the grill grates and smoke it for about 30 minutes until it's fully cooked and has a smoky flavor. Remove from heat and let it cool.
In a mixing bowl, combine the softened cream cheese, mayonnaise, sour cream, lemon juice, chopped dill, red onion, Worcestershire sauce, garlic powder, salt, and pepper. Mix and combine all the ingredients well.
Flake the smoked tuna into smaller pieces and add it to the cream cheese mixture. Stir gently to incorporate the tuna evenly throughout the dip.
Transfer the Schooners Smoked Tuna Dip to a serving platter, smoothing the top with a spoon or spatula. For enhanced flavor, cover the dip with plastic wrap and refrigerate for at least 1 hour before serving.
When ready to serve, garnish the dip with additional chopped dill and a few slices of lemon. Pair it with your favorite crackers, toasted baguette slices, or fresh vegetables for dipping.
