Our take on the classic French spread wins the party-food triple crown—quick, easy, and delicious. It's also kosher and great on matzoh—ideal for a seder!
In a medium skillet, heat olive oil over medium. Add onion and saute until golden, about 10 minutes. Let cool slightly; transfer to a food processor with salmon, dill, mayonnaise, mustard, and lemon juice and zest. Pulse until just combined. Transfer to serving dish and garnish with more dill. Serve with matzoh or store in refrigerator, covered, up to 3 days.
We like Ducktrap River of Maine brand hot-smoked salmon, available at most grocery stores, for its nice balance of salty and sweet.
