INGREDIENTS - Pork tenderloin - EVOO - Yellow onions - White button mushrooms - Butter - Balsamic vinegar - Seasonings: Dried oregano, Garlic powder, Onion powder, Ground pepper, Salt
You can make the Caramelized Onions & Mushrooms a day or two ahead and store them in the fridge or make them while you cook the pork tenderloin.
Heat the olive oil in a skillet and when its hot, stir in the onions and add the salt and pepper. Stir them occasionally as they begin to caramelize, letting them turn golden brown.
Add in the sliced mushrooms and let them cook about 10 minutes.
Once the mushrooms are cooked, stir in the balsamic vinegar with the oregano and cook a final 10 minutes.
Sprinkle the seasonings over the pork tenderloin and then place in the oven with the broiler turned on. Finally, turn it to roasting at 400 for 15 minutes or until the internal temperature reaches 145 F.
When the pork is done cooking, let it rest for 10 minutes tented with aluminum foil to allow the juices to redistribute. Then slice the tender pork tenderloin and serve with the Caramelized Onions and Mushrooms.
