01 - Pat the chicken breasts dry with paper towels. Season both sides generously with salt and black pepper. Dust lightly with flour, shaking off any excess.
02 - Heat olive oil in a large skillet over medium-high heat until shimmering. Add chicken breasts and sear for 4 to 5 minutes per side until golden brown and 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 melt. Add minced garlic and sauté for 1 minute until fragrant, being careful not to burn.
04 - Stir in chopped sun-dried tomatoes and dried Italian herbs. Cook for 2 minutes, stirring frequently to combine flavors.
05 - Pour in chicken broth and scrape up any browned bits from the bottom of the skillet with a wooden spoon. Let simmer for 1 minute to reduce slightly.
06 - Add heavy cream, grated Parmesan cheese, lemon juice, and crushed red pepper flakes. Stir until cheese melts and sauce is smooth. Simmer for 3 to 4 minutes until sauce thickens enough to coat the back of a spoon.
07 - Return chicken breasts to the skillet, spooning sauce over the top. Simmer for 5 minutes until chicken is heated through. Garnish with chopped fresh basil or parsley and serve immediately over pasta, rice, or steamed vegetables.
