Slice the bagel in half horizontally and lightly toast it to your desired level of crispiness.
Spread cream cheese on both halves of the toasted bagel.
Layer the smoked salmon on top of the cream cheese, dividing it evenly between the two bagel halves.
Sprinkle capers over the smoked salmon. Capers add a tangy and briny flavor that complements the richness of the salmon.
Arrange thinly sliced red onion on top of the capers. Red onion adds a subtle bite and a hint of sweetness to the bagel.
Garnish with chopped fresh dill. Dill adds a bright and herbaceous flavor that pairs beautifully with the smoked salmon.
Season with salt and pepper to taste. The smoked salmon and cream cheese already have some saltiness, so taste before adding additional salt.
If desired, squeeze fresh lemon juice over the smoked salmon for a burst of citrusy flavor.
Assemble the bagel by placing the top half of the bagel over the smoked salmon and gently pressing down to secure the toppings.
Serve your Smoked Salmon Bagel immediately, either as an open-faced sandwich or closed. Enjoy it for breakfast, brunch, lunch, or a light dinner!
