Preheat the oven to 375°F. Butter a rimmed sheet pan or casserole dish.
Place the fish fillets in the buttered pan.
In a bowl, mix together the cream, mustard, and dill. Pour over the fish.
Bake for 20 to 25 minutes, until the fish flakes in the
center.
Notes
To ensure your salmon turns out perfectly cooked, check for doneness by gently flaking the fish with a fork in the center; it should easily separate and look opaque. Be careful not to overcook, as salmon can dry out quickly!
Give the salmon enough space on the pan to ensure it cooks evenly and crisps up nicely.
Salmon if fully cooked when it reaches 145°F for the perfect texture.
The sauce thickens slightly as it cools, so it's okay if it seems a little light coming out of the oven.
