Preheat your oven to 375°F and prepare a large piece of foil on a baking sheet.
Rub the salmon fillet with salt and pepper. Set aside.
In a bowl, whisk together olive oil, lemon juice, dijon mustard, honey, dill, garlic powder, and onion powder to make the marinade.
Place the salmon in the center of the foil and pour the marinade over it, spread sliced lemon and dill sprigs on top.
Fold the foil edges securely to create a sealed packet.
Bake in the oven for 25 minutes or until the salmon flakes easily with a fork.
While baking, prepare tartar sauce by mixing Greek yogurt, chopped dill pickles, lemon juice, and a pinch of garlic powder.
Once cooked, carefully open the foil, place a tablespoon of cold butter on top of the salmon, and broil for 2-3 minutes until melted and slightly caramelized.
Remove from oven, let rest for 5 minutes, then serve with tartar sauce.
Notes
This baked salmon is perfect with a side of steamed vegetables or a fresh salad.
