Preheat oven to 375°F (190°C), positioning a rack in the center.
In a bowl, mix softened butter with lemon juice to make lemon butter. Set aside.
Pat chicken breasts dry and season with lemon pepper and kosher salt.
In a large oven-safe skillet over medium-high heat, melt 3 tablespoons of lemon butter. Sear chicken 4–5 minutes per side until golden. Transfer to a plate.
Deglaze skillet with white wine, scraping up brown bits with a wooden spoon.
Nestle seared chicken back into the skillet. Add asparagus, garlic, and artichoke hearts. Season with salt and dot remaining lemon butter over the top.
Transfer skillet to oven and bake for 15–20 minutes, or until chicken reaches 165°F (74°C) internal temperature.
Finish with fresh basil, lemon zest, and a squeeze of lemon juice.
Serve hot with crusty bread, rice, or pasta.
