Equipment: Nice-to-haves
- Meat thermometer (for perfect doneness)
- Tongs (for flipping the tenderloin)
- Mixing bowl (for sauce slurry)
- Serving platter

Ingredients
- 1 pork tenderloin (about 1 pound)
- 8 ounces mushroom, sliced
- 1 small onion, sliced
- 1 clove garlic, minced
- 1 cup chicken broth
- 1/4 cup dry white wine (optional, adds brightness)
- 2 tablespoons soy sauce
- 2 tablespoons butter
- 1 tablespoon olive oil
- 1 teaspoon dried thyme
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon cornstarch
- 1 tablespoon water
- 1 bay leaf
- 1 tablespoon Worcestershire sauce (optional, for depth)
- 2 tablespoons sour cream (optional, for creaminess at the end)
- 1 tablespoon parsley, chopped (for garnish)

Instructions
- Pat the pork tenderloin dry and season it all over with salt, pepper, and dried thyme.
- Heat the skillet over medium-high heat and add the olive oil and butter.
- Sear the tenderloin on all sides until golden brown to lock in juices.
- Remove the tenderloin and use the same skillet to sauté the onion until translucent.
- Add the garlic and mushroom to the skillet and cook until the mushroom releases its liquid and starts to brown.
- Deglaze the skillet with the white wine, scraping up any browned bits for extra flavor.
- Stir in the soy sauce and Worcestershire sauce to the skillet and let it simmer briefly.
- Transfer the sautéed mushroom and onion mixture to the slow cooker.
- Place the seared pork tenderloin on top of the vegetables in the slow cooker.
- Pour the chicken broth around (not directly on) the tenderloin to keep the sear flavor intact.
- Tuck the bay leaf into the broth so it can work its magic slowly.
- Cover and cook on low until the pork is tender and reaches a safe internal temperature.
- When the pork is nearly done, remove it to a serving platter and tent it to rest.
- Make the gravy by whisking the cornstarch with water in the mixing bowl to make a slurry.
- Pour the cooking liquid into the skillet and bring it to a simmer over medium heat.
- Whisk in the cornstarch slurry until the sauce thickens to a glossy gravy.
- Stir the sour cream into the gravy off the heat for a silky finish, if using.
- Slice the rested pork tenderloin into medallions and spoon the mushroom gravy over the top.
- Garnish with chopped parsley and serve immediately with your favorite side.
What Else You Should Know
Tip: Searing the pork first gives you a deeper flavor and prettier color. It’s worth the extra five minutes.
Variation: Swap the white wine for extra chicken broth if you prefer alcohol-free cooking. The dish will still be comforting and homey.
Serving suggestion: Pair the sliced pork with mashed potato or buttery noodle and a green vegetable to soak up the mushroom gravy. Make-ahead: You can cook the tenderloin a day in advance and refrigerate the sliced meat and gravy separately.
Reheat gently so the pork stays juicy. Thickening trick: If your gravy needs more body, mash a few mushroom pieces into the sauce before adding the cornstarch slurry.
Health note: Pork tenderloin is a lean cut and is high in protein while being relatively low in fat, so this feels indulgent but can be part of a balanced meal. Final nugget: Use a meat thermometer for reliable results.
Aim for the internal temperature to hit the safe range, then rest the meat so juices settle and the slices stay tender. Good luck—and enjoy the compliments.
