These pork tenderloin medallions with a mushroom pan sauce make a savory, umami-packed meal that’s excellent served over rice, pasta, or mashed potatoes. Tender pork medallions and a silky mushroom sauce are cooked in one skillet for an easy, comforting dinner.
In colder months we crave rich, satisfying dishes, and this recipe delivers. While I enjoy many winter braises and soups, this skillet pork with mushroom sauce is a quick, hearty option that still feels special. The key is building layers of flavor in one pan and slicing the tenderloin into medallions so the pork cooks quickly and evenly.
Ingredients & Substitutions
Below are the ingredients I usually use and a few substitution ideas so you can adapt the recipe to what you have on hand without losing the depth of flavor.
- Pork Tenderloin – I use a 1.5 lb tenderloin, sliced into 1–1½” medallions. You can substitute boneless pork chops cut to similar thickness if needed.
- Sweet Onion – Adds a touch of sweetness that balances the savory sauce. Yellow or white onion work fine too.
- Mushrooms – Use any meaty mushrooms you like: shiitake, cremini (baby bella), portobello, or king oyster. The mushroom variety changes nuance but the sauce remains delicious.
- Garlic – Fresh garlic is best; if you must use granulated garlic, use about one-third the amount by volume.
- Broth – Mushroom or beef broth gives the most depth, but chicken or vegetable broth will work in a pinch.
- Worcestershire – An important umami booster in the sauce. If you don’t have it, you can experiment with pantry blends, but Worcestershire will deliver the best flavor.
- Red Wine Vinegar – I prefer its brightness here; a young or golden balsamic or apple cider vinegar are acceptable substitutes.
- Flour + Butter – A simple roux thickens the sauce. If you prefer, use cornstarch (about 2 teaspoons cornstarch mixed with 1 teaspoon cold water) added at the end to thicken.
- Oil – For searing: olive, canola, grapeseed, or even rendered bacon fat are all fine.
- Salt, Pepper, Garlic Powder – Season the pork before searing to ensure well-rounded flavor.
Tips for Tender Pork Medallions and Creamy Mushroom Pan Sauce
These practical tips come from repeated testing and will help you get the best texture and flavor from this one-pan dish.
- Prep ahead. Chop the vegetables and measure ingredients before heating the pan so you aren’t scrambling while cooking.
- Season as you go. Taste the onions and mushrooms while they cook and adjust salt to build balanced flavor; taste the sauce before serving and finish seasoning if needed.
- Avoid overcooking the pork. Sear the medallions in a hot pan, then remove them. Return them to the sauce just long enough for the internal temperature to reach 145°F for juicy results.
- Adjust heat as needed. Use high heat to get a good sear, then lower to medium for caramelizing onions and mushrooms so they brown without burning.
- Be patient with caramelization. Allow mushrooms and onions a few extra minutes to get nicely browned — that color carries a lot of the sauce’s flavor.
FAQ’s
Here are answers to a few common questions cooks ask about this recipe.
Pork is safe to eat at 145°F. Cooking to this temperature keeps the meat tender and juicy; higher temperatures dry it out.
You can rehydrate dried mushrooms in hot water, chop them, and even use the soaking liquid as part of the broth. Texture and flavor will differ from fresh mushrooms.
Yes. Because the sauce is not dairy-thickened, leftovers freeze well. Refrigerate for a few days or freeze; thaw in the fridge before reheating.
Serving Suggestions
I like serving these pork medallions over rice or pasta to soak up the silky sauce. Mashed potatoes, mashed cauliflower, or crusty bread are also excellent choices. For a more casual side, cornbread or garlic bread rolls complement the dish well.
Pair the meal with a robust vegetable: roasted garlic broccoli, sautéed greens, or crispy Brussels sprouts are all good matches that stand up to the savory sauce.
I hope you enjoy these juicy pork medallions. When the sauce is this good, a starch and a green vegetable are all you need for a satisfying, homey dinner.

Pin Recipe
Ingredients
- 1 1/2 lbs pork tenderloin, sliced*
- 1/2 teaspoon black pepper
- 1/2 teaspoon garlic powder
- 1/2 teaspoon kosher salt, plus extra to taste
- 1 tablespoon oil
- 4 tablespoons unsalted butter, divided
- 1 1/2 cups sweet onion, diced (about 1 large)
- 2 cups mushrooms, diced (about 8 ounces)
- 1 tablespoon red wine vinegar
- 1 tablespoon minced garlic (about 3 large cloves)
- 2 tablespoons flour
- 1 1/2 cups mushroom or beef broth
- 4 teaspoons Worcestershire sauce
- 1/4 cup chopped parsley (optional)
Instructions
- Slice the pork tenderloin into 8 pieces, about 1 to 1½” each.
- Season the medallions with salt, pepper, and garlic powder.
- Heat a large rimmed skillet over medium-high. Add 1 tablespoon butter and the oil when the pan is hot.
- Sear the pork 2–3 minutes per side until browned, then remove to a plate and set aside.
- Reduce heat to medium. Add the onions, mushrooms, red wine vinegar, 1 tablespoon butter, and a pinch of salt. Cook, stirring occasionally, until the vegetables are caramelized, about 8–10 minutes.
- Turn heat to medium-low. Add the minced garlic and remaining butter; when the butter melts, sprinkle in the flour and stir constantly for 2 minutes to cook the roux.
- Slowly whisk in the broth until smooth, stir in the Worcestershire sauce, and return the pork medallions to the pan.
- Bring the pan back to medium and simmer, stirring occasionally, until the sauce thickens and the pork reaches 145°F. Taste and adjust seasoning, then serve immediately.
