Coat the top of the salmon with a light layer of digon mustard. Spread the parmesan mixture over the top of the salmon. Bake at 350ºF until the top is golden brown and crisp.
For the sauce, melt 1 tbsp butter over medium-low heat. Add the shallots and garlic and simmer until translucent. Next add the chicken stock, and white wine.

Serve the lemon cream sauce on the side.
