In a shallow bowl, stir together the flour, thyme, salt, and pepper, reserving 3 Tbsp flour for the sauce. Coat both sides of pork with flour mixture.
In a large skillet over medium-high heat, heat 2 Tbsp butter. Add pork and cook 6 to 8 minutes, turning once, until temperature reaches at least 145 degrees. Remove and keep warm.
Heat remaining 2 Tbsp butter in skillet and add mushrooms and garlic. Saute, stirring frequently, until mushrooms are lightly browned.
Sprinkle remaining flour over mushroom mixture and cook and stir 2 minutes. Add chicken broth, cream, and Marsala. Heat to boiling. Reduce heat to low and simmer until thickened. Add pork and coat with sauce. Serve over noodles, mashed potatoes, rice, or zoodles, and enjoy!
