Instructions
Season the pork pieces with salt and black pepper. Heat the oil and 1 tablespoon of the butter together in a large skillet over medium-high heat. Add the pork and cook until lightly browned on both sides. Transfer the pork to a plate.
Add the remaining butter to the pan. When the butter is bubbly, add the mushrooms and cook for 3 to 5 minutes, until soft. Add the garlic and thyme and stir to coat. Cook for 1 minute, until fragrant. Add the wine or broth and Dijon mustard and bring to a simmer. Reduce the heat to low and add the cream.
Return the pork to the pan with any accumulated juices from the plate. Simmer for 3 to 5 minutes, until the pork is cooked through, and the sauce thickens.
