Trim the pork tenderloin of any silver skin, then cut it into medallions approximately 1 1/4 inches (3-4 cm) thick. Season both sides generously with salt and pepper.
Heat the olive oil and butter in a large skillet over medium-high heat. Sear the pork tenderloin medallions for 2-3 minutes per side, until golden brown.
Remove the seared pork from the skillet and set aside on a plate to rest.
In the same skillet, sauté the finely chopped onion until softened. Add the minced garlic and sliced mushrooms. Cook for 5-6 minutes, until the mushrooms have released their liquid and are tender.
Deglaze the pan with white wine, scraping up any browned bits from the bottom. Let it simmer for 2 minutes to allow the alcohol to evaporate, then stir in the heavy cream.
Return the pork tenderloin medallions to the skillet and reduce the heat to low. Simmer for another 5 minutes, allowing the flavors to meld together and the pork to cook through.
Garnish with fresh parsley and serve with mashed potatoes, rice, or a fresh salad.
