• Preheat oven to 450°F
• Line a rimmed baking sheet with foil or parchment paper.
• Place the baking sheet in the hot oven for 5 minutes.

  Remove pan from oven and spray with non-stick spray or brush lightly with a teaspoon of olive oil.
• Place salmon, skin side down, on the hot pan. Drizzle with the remaining 2 teaspoons of olive oil and scatter dill all over. Sprinkle with salt and pepper.
• Place pan in the oven and cook 10 minutes for every 1" thickness of salmon.
• When there is about 1 minute left to cook layer sliced lemons on top, if not drizzling with the Mustard Dill Sauce later for added flavor.

Making the Mustard Dill Sauce:

• In a small heavy-bottom saucepan add heavy cream.

  Bring to a boil, whisking frequently, and then reduce heat to a medium simmer. Reduce the cream until thickened to sauce consistency. The sauce is ready when you stir the sauce with a spoon and then immediately trace a line across the back of the spoon.

  Remove from heat and whisk in mustard, dill, salt, and pepper.

Serving Instructions:

• Remove salmon from the oven and allow it to rest on the baking sheet for 10 minutes. This is important so don't skip this step!
• Carefully loosen and remove salmon to a prepared platter using 2 large spatulas.
• Drizzle with Dill Mustard Sauce. Serve the remaining sauce in a small dish on the side.
