Trim excess fat from the chicken and cut into 1-inch cubes.
Heat 1 tablespoon olive oil in a large skillet over medium heat. Add the chicken and cook, stirring occasionally, until cooked through (no longer pink), about 6–8 minutes. Remove the chicken to a plate and set aside.
Add the remaining 1 tablespoon olive oil to the skillet and warm over medium heat. Add the minced garlic and cook until fragrant, about 1–2 minutes.
Sprinkle the flour into the skillet and whisk briskly until a paste forms and the flour is cooked, about 1 minute.
Slowly pour in the chicken broth while whisking to smooth out any lumps. Then slowly whisk in the milk. Add the seasoned salt and pepper and simmer over medium-low until the sauce begins to thicken, about 2–3 minutes.
Stir the uncooked bowtie pasta into the sauce, increase heat to high and bring to a boil. Reduce heat to medium-low, cover, and cook 13–16 minutes, stirring occasionally, until the pasta is tender and most liquid is absorbed.
Add the cream cheese (cut into pieces) and grated Parmesan to the skillet and stir until melted and the sauce is smooth.
Return the cooked chicken to the pan, stir to combine, and heat through for 1–2 minutes.
Garnish with fresh parsley and serve immediately.
