- Pat the salmon fillets dry with paper towels and season both sides with salt and pepper. 
- Heat olive oil in a large skillet over medium-high heat. Sear salmon fillets for 4–5 minutes per side, then remove and set aside. 
- In the same skillet, reduce heat to medium and add garlic. Cook for about 1 minute until fragrant. 
- Pour in the chicken broth and use a wooden spoon to scrape up any bits stuck to the bottom. 
- Stir in the sun-dried tomatoes and let simmer for 2 minutes. 
- Add heavy cream, Parmesan cheese, and Italian seasoning. Stir and let simmer gently until thickened, about 3–4 minutes.

- Return the salmon to the skillet and spoon the sauce over the fillets. 
- Garnish with fresh basil if desired and serve warm.
