Preheat oven to 350°F (175°C) and grease a large baking dish.
Season pork chops with salt and pepper. Heat oil in a skillet and sear chops 2–3 minutes per side; set aside.
In the same skillet, sauté onions in butter until soft; add garlic and cook 30 seconds.
Sprinkle flour over onions and stir 1 minute. Gradually add broth and cream, stirring until smooth. Season with thyme, paprika, salt, and pepper.
Layer half of the sliced potatoes in the baking dish. Spoon some sauce over the potatoes.
Place pork chops on top, then add remaining potatoes and pour over the remaining sauce.
Cover tightly with foil and bake 45 minutes.
Remove foil and bake 15 minutes more, until potatoes are tender and the top is lightly golden.
Rest 5 minutes before serving.
