Heat the oven to 375°F. Line a baking pan with parchment paper or foil and set aside.
Rinse the chops under warm running water to remove any bone fragments, then pat them dry with a paper towel.
Mix the thyme, garlic powder, onion powder, paprika, salt, and some freshly ground black pepper. Evenly coat both sides of the pork chops with the seasoning.
Spread the flour onto a plate. Press each pork chop into the flour, making sure they are well coated on all sides, then shake off the excess.
Heat the butter and olive oil in a large skillet over medium-high heat until the butter begins to foam. Sear the chops for 2-3 minutes on each side until golden brown. Transfer them to the prepared baking pan.
Place the chops in the oven and bake for about 8 minutes, or until they reach an internal temperature of 145°F. Once done, remove from the oven and let them rest.
Add the onions, mushrooms, and garlic. Cook over medium heat for 5-6 minutes until the onions soften.
Turn off the heat and whisk in 2 tablespoons of the remaining flour until fully absorbed. Slowly pour in the chicken broth while whisking to prevent lumps.
Return the heat to medium and cook for 3-4 minutes until the gravy thickens. Stir in the heavy cream, season to taste, and spoon the gravy over the resting pork chops.
Serve & enjoy!
