Preheat oven to 400°F. Line a sheet pan with parchment.
Place salmon fillets on the sheet pan with parchment and pat dry.
In a small sauce pan, melt the butter, then add in the garlic and lemon slices. Let simmer until fragrant.
Pour the lemon butter garlic sauce on top of the salmon evenly.
Bake 12-15 minutes or until all the sides are opaque.
Notes
Salmon can overcook pretty quickly and become chewy. If you are nervous about that, try to ask for a salmon filet that is not as thick in the center. The thickness of the salmon will impact the cook time, so adjust by 1-2 minutes accordingly.Be sure to cover the entire piece of fish with the lemon, garlic, and butter sauce before baking. You can use a spoon to do this or a basting brush.Top with a slice of lemon and an additional squeeze of lemon juice before baking to give it another kick of citrus and acid.
