Cook the linguine according to package instructions until al dente. Drain and set aside.
In a large skillet, heat olive oil over medium heat. Season the chicken pieces with salt and pepper, then add them to the skillet. Cook for about 5-7 minutes, or until the chicken is browned and cooked through.
Add the minced garlic, smoked paprika, oregano, and red pepper flakes to the skillet. Sauté for an additional 1-2 minutes until the garlic is fragrant.
Pour the melted butter and lemon juice over the chicken mixture, stirring to combine.
Add the cooked linguine to the skillet and toss everything together until the pasta is well coated.
Remove from heat and sprinkle with fresh parsley and grated Parmesan cheese before serving.
