Season the pork chops generously on one side with salt and freshly ground black pepper; set aside.
In a large skillet over medium heat, add garlic infused oil and when hot, place chops with seasoned side down; season the top side with salt and pepper. Cook until brown and then place them on a baking sheet. Transfer the pork chops to a 200ºF preheated oven to keep them warm while making the sauce.
Return the skillet on medium heat and add clarified butter. When hot, add onions and sauté for 1 minute. Add garlic and sauté for 30 seconds. Pour in chicken broth and then pumpkin purée; stir to combine.
Reduce heat to medium-low and add sriracha, Herbes de Provence, pumpkin pie spice, ground sea salt and freshly ground black pepper; stir and cook for 2 minutes. Add brown sugar and heavy cream; stir and bring the mixture back to a simmer, about 2 minutes.
Spoon sauce over pork chops and put any extra sauce in a small bowl or ramekin. Makes 4 servings.
