Soften cream cheese in a microwave-safe bowl for about 30 seconds.

Slice chicken breasts lengthwise and season with garlic powder, salt, and pepper.

In a skillet over medium-high heat, melt butter and olive oil. Add chicken and cook until golden brown on both sides (about 5-6 minutes per side). Remove from skillet.

Lower heat, add chopped onion to the same skillet, and sauté until softened (5-7 minutes). Add minced garlic and cook for another 30 seconds.

Stir in softened cream cheese and chicken broth until smooth. Add Italian seasoning and crushed red pepper flakes.

Return chicken to the skillet and coat with the sauce. Heat through for 2-3 minutes.

Garnish with fresh parsley if desired before serving.
