Heat 2 tablespoons olive oil in a skillet over medium heat. On a large plate, toss the flour, garlic powder, onion powder, and a pinch each of salt and pepper. Dredge both sides of the salmon filets in the flour mixture, shaking off excess, and place into the skillet skin-side down (or, if using skinless, whichever side might have been the skin side). Sear 4-5 minutes per side until crisp and golden. Move to a clean plate.
Melt the butter in the same skillet and stir in the garlic and Italian seasoning until fragrant, about 1 minute. Pour in the wine and simmer until reduced by half, about 2-3 minutes, then stir in the broth, heavy cream, spinach, and parmesan. Cook until the sauce thickens and the spinach wilts, about 4-5 minutes. Taste and adjust salt and pepper as needed.
Nestle the salmon filets and juices into the pan and heat until warmed through, basting the fish with the sauce.
Divide the salmon filets over bowls of potatoes, rice, or polenta. Enjoy!
