Cook the linguine according to package instructions until al dente. Drain and set aside.
In a large skillet, season the chicken pieces with salt and black pepper. Heat olive oil over medium-high heat in the skillet.
Add the chicken and cook until browned and cooked through, about 5-7 minutes. Remove the chicken from the skillet and set aside.
In the same skillet, reduce the heat to medium and add the butter. Once melted, add the minced garlic, smoked paprika, onion powder, and cayenne pepper. Sauté for about 1-2 minutes until fragrant.
Stir in the heavy cream and bring to a simmer. Add the cooked chicken back into the skillet, along with the grated Parmesan cheese and lemon juice. Stir until the cheese is melted and the sauce is well combined.
Add the cooked linguine to the skillet and toss to coat the pasta in the sauce. Cook for an additional 2-3 minutes to heat through.
Garnish with chopped parsley before serving.
