Caramelized Onions & Mushrooms on Pork Tenderloin is such a flavorful main dish! The pork tenderloin is moist and juicy and topped with Onions & Mushrooms that are sauteed low and slow with a touch of balsamic to bring out all of the natural sugars and caramelize them to perfection.
Push the onions over to one side of the skillet and add the Ghee or butter to the open space and then the mushrooms. Saute the mushrooms for 10 minutes until browned.
Then mix the onions and mushrooms together, add the oregano and balsamic vinegar, and cook down for a final 10 minutes.
