Season and dredge: Pat the pork chops dry. Mix salt, pepper, garlic powder, and paprika.
Season both sides, then lightly dredge the chops in 2 tablespoons flour, shaking off excess.
Sear the chops: Heat olive oil in a large skillet over medium-high. Add chops and sear 3–4 minutes per side until well browned. Transfer to a plate; they will finish cooking in the sauce.
Sauté aromatics: Reduce heat to medium.
Add butter, then the onion and mushrooms with a pinch of salt. Cook 6–8 minutes, stirring occasionally, until softened and lightly browned. Add garlic and cook 30 seconds until fragrant.
Build the roux: Sprinkle 2 tablespoons flour over the vegetables.
Stir for 1 minute to cook off the raw flour taste.
Add liquids: Slowly whisk in chicken broth, scraping up browned bits. Stir in cream, Dijon, Worcestershire, and thyme. Bring to a gentle simmer; the sauce will thicken slightly.
Return chops to the pan: Nestle the pork chops into the gravy.
Reduce heat to low, cover, and simmer 6–10 minutes, turning once, until the chops are just cooked through. Target 145°F internal temperature for juicy chops.
Adjust and finish: Taste the sauce and add salt and pepper as needed. If the sauce is too thick, splash in more broth or cream. If too thin, simmer uncovered a few minutes.
Garnish with parsley and serve hot.
