01 - Pat salmon fillets completely dry with paper towels. Season both sides generously with kosher salt and freshly ground black pepper, pressing gently to adhere.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Place salmon fillets in the pan and sear for 3-4 minutes per side until golden brown and just cooked through. Transfer to a plate and cover loosely with foil to keep warm.
03 - Reduce heat to medium. Add butter to the same skillet and let it melt. Add minced garlic and sauté for 30 seconds until fragrant, being careful not to burn it.
04 - Pour in chicken or vegetable broth, using a wooden spoon to scrape up any browned bits from the bottom of the pan. Let simmer for 2 minutes until slightly reduced.
05 - Stir in heavy cream, grated Parmesan cheese, chopped sun-dried tomatoes, Italian seasoning, and crushed red pepper flakes. Simmer for 3-4 minutes, stirring frequently, until sauce thickens and coats the back of a spoon.
06 - Add fresh lemon juice to the sauce. Return salmon fillets to the skillet, spooning the sauce generously over each piece. Simmer for 2 minutes until everything is heated through.
07 - Remove from heat. Sprinkle with chopped fresh basil or parsley. Serve immediately over rice, pasta, or with crusty bread to soak up the sauce.
