Pat pork dry. Slice into 1-inch medallions and flatten lightly with your palm.
Season pork with salt, pepper, and paprika. Dust all sides with flour, shaking off any excess.
Heat olive oil and half the butter in a large skillet over medium-high heat.
Sear pork 2–3 minutes per side until browned. Transfer to a plate and tent loosely with foil.
Lower heat to medium. Add remaining butter, onion, and mushrooms. Cook until softened and lightly browned, about 5 minutes.
Stir in garlic and thyme. Cook 30 seconds until fragrant.
Pour in broth and lemon juice. Scrape up browned bits and simmer 2 minutes to reduce slightly.
Whisk in Dijon and cream. Simmer gently until the sauce thickens, 2–3 minutes.
Return pork and any juices to the pan. Simmer until just cooked through, 3–5 minutes, or 145°F internally.
Rest 2 minutes off heat. Sprinkle with parsley and spoon sauce over to serve.
Notes
Swap thyme for rosemary, or stir in a spoonful of whole-grain mustard for extra texture. Serve over mashed potatoes, buttered egg noodles, or rice to catch the sauce. Leftovers keep well in the fridge up to 3 days; rewarm gently so the pork stays tender.This recipe is an original creation inspired by classic Pork Tenderloin Skillet Recipe flavors.
