Sprinkle the salmon with onion powder, garlic powder, salt, and pepper. Lightly coat each piece in flour.
Melt butter in a skillet on medium-high heat. Place the salmon in the skillet and cook for 3 to 4 minutes per side, until golden brown. Take the salmon out and set it aside.
In the same skillet, combine chicken broth, lemon juice, dried oregano, dried basil, and Dijon mustard. Stir this mixture and allow it to bubble for 1-2 minutes. Then, add the cream and simmer for about 3-5 minutes. Reintroduce the salmon to the pan.
Cook a few more minutes until the sauce thickens and the salmon is cooked through. Garnish with fresh parsley before serving.
