Season the Chicken: Toss chicken with salt, pepper, Italian seasoning, and paprika until evenly coated.
Cook the Chicken: Heat olive oil in a large skillet over medium-high heat. Add chicken in a single layer and cook for 3–4 minutes per side until golden and cooked through. Remove and set aside.
Build the Base: In the same skillet, melt butter with olive oil over medium heat. Add garlic and sauté for 40–60 seconds until fragrant.
Make the Sauce: Stir in heavy cream, chicken broth, tomato paste, salt, and pepper. Bring to a gentle simmer.
Cook the Gnocchi: Add gnocchi and sun-dried tomatoes. Cover and cook for about 4 minutes until gnocchi is tender and sauce thickens slightly.
Combine Everything: Stir in spinach, Parmesan, and cooked chicken. Add lemon juice and toss until everything is well combined and spinach is wilted.
Finish: Remove from heat once creamy and fully combined.
Serve: Top with fresh basil and extra Parmesan if desired. Serve warm.
