Heat a large oven-safe skillet over medium heat and add 1 tbsp butter. Once melted, add the shallot and garlic. Sauté for about 3-5 minutes or until translucent.
Add the white wine and let cook down for about 3 minutes or until reduced by half.
Whisk the chicken broth and flour in a bowl until combined. Pour into the pan along with the heavy cream.
Bring the mixture to a simmer, whisking frequently until slightly thickened, about 2-4 minutes. Remove from the heat and stir in the parmesan until combined. Taste and add salt and pepper if needed.
Preheat the oven to 400 degrees Fahrenheit.
While the oven preheats, melt the remaining tbsp of butter in a medium sized bowl. Mix the melted butter with the breadcrumbs, garlic powder, and a generous pinch of salt and pepper.
Place the salmon filet into the center of the pan in the cream sauce. Only about ½ of the salmon should be submerged.
Sprinkle the breadcrumb mixture over the top of the salmon evenly. Bake for about 12-20 minutes or until the salmon is cooked to desired doneness. Baking time may vary based on the thickness of your fillet.
Serve and garnish withmore parmesan and parsley if desired!
