Preheat your oven to 375°F (190°C).
Season the pork chops with garlic powder, onion powder, salt, and pepper.
Heat olive oil in a large skillet over medium-high heat.
Sear the pork chops for 3-4 minutes on each side until golden brown.
Remove the chops from the skillet and set aside.
In the same skillet, add butter and sliced mushrooms.
Sauté the mushrooms until they are soft and browned.
Stir in heavy cream, Dijon mustard, and fresh thyme.
Return the pork chops to the skillet, coating them with the sauce.
Transfer the skillet to the oven and bake for 10-15 minutes until the pork is cooked through.
