Heat oven to 350ºF (180ºC). In a small bowl stir together the poppy seeds, sesame seeds, salt, onion powder and garlic powder then set aside.
Add olive oil to a shallow bowl. Dip one side of each bagel round in the olive oil and arrange in a single layer on a baking sheet. Sprinkle 2 teaspoons of the everything bagel seasoning mixture evenly over the top. Bake the rounds until they are crisp, about 16 minutes.
Let cool completely and store in an airtight container until ready to use.
For the smoked salmon tartare:
In a medium bowl stir together the salmon, olive oil, shallot and half the chives.
Use a 3” cookie cutter or biscuit cutter and pile the salmon inside to shape it. Carefully lift the cookie cutter off the salmon.
Top with the creme fraiche, remaining chives, dill and lemon zest. Serve with the bagel crisps on the side.
