Craving a cozy dinner that practically cooks itself while you binge a show? Slow cooker pork tenderloin with mushroom wine sauce is your new best friend.
It’s tender, saucy, and fancy enough to impress without pretending you trained at culinary school. But here’s the catch!
It tastes like you worked all day, even if you only stirred once.

Equipment: Must-haves
- Slow cooker
- Skillet (oven-safe if you have one)
- Cutting board
- Knife
- Measuring spoon
- Measuring cup
- Tong
- Wooden spoon
Equipment: Nice-to-haves
- Immersion blender (for silky sauce)
- Meat thermometer (for perfect doneness)
- Trivet (to lift the pork from juices)
Ingredients
- 1 pound pork tenderloin, trimmed and patted dry
- 1 tablespoon olive oil
- 1 small onion, thinly sliced
- 8 ounces cremini mushroom, sliced
- 2 cloves garlic, minced
- 1/2 cup dry red wine (choose something you’d sip, not a mystery box)
- 1 cup low-sodium chicken stock
- 1 tablespoon Worcestershire sauce
- 1 tablespoon Dijon mustard
- 1 tablespoon tomato paste
- 1 teaspoon dried thyme
- 1 bay leaf
- 1 tablespoon butter
- 1 tablespoon cornstarch
- 2 tablespoons cold water
- Salt, to taste
- Freshly ground black pepper, to taste
- Fresh parsley, chopped (for garnish)
Instructions
- Season the pork generously with salt and pepper on all sides and let it sit while you heat the skillet.
- Heat the skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the pork on all sides until it develops a golden crust and looks proud, then transfer it to the slow cooker.
- In the same skillet, add the onion and mushroom and sauté until they soften and start to brown, scraping up any tasty browned bits from the pan.
- Add garlic to the skillet and cook briefly until fragrant, stirring like you mean it.
- Pour the red wine into the skillet to deglaze, scraping the bottom with a wooden spoon to release flavor, and let the wine reduce by about half.
- Stir the chicken stock, Worcestershire sauce, Dijon mustard, tomato paste, dried thyme, and bay leaf into the skillet and bring the mixture to a simmer.
- Taste the sauce and season with a little salt and pepper if it needs help finding its voice.
- Pour the sauce and mushroom mixture over the pork in the slow cooker so the tenderloin gets cozy in the liquid.
- Cover and cook on low until the pork is tender and cooked through, checking with a meat thermometer if you have one.
- When the pork reaches the desired doneness, remove it to a cutting board and tent it to rest while you finish the sauce.
- Skim excess fat from the slow cooker liquid if needed, then transfer the liquid to the skillet and bring to a gentle simmer.
- Whisk the cold water and cornstarch together until smooth, then whisk the slurry into the simmering sauce until it thickens to a glossy finish.
- Stir the butter into the sauce off the heat for a silky sheen, and adjust seasoning to taste.
- Slice the pork against the grain and arrange it on a plate or cutting board, spoon the mushroom wine sauce over the slices, and sprinkle with chopped parsley before serving.
What Else You Should Know
Tip: Searing the pork first builds flavor. That’s why you shouldn’t skip it even though the slow cooker does most of the work.
Variation: Swap the red wine for marsala if you want a richer, slightly sweeter sauce. Or use extra chicken stock for a wine-free option.
Serving suggestion: Serve with creamy mashed potato or buttery noodle to mop up the mushroom wine sauce, and a simple green on the side for color (and to fake health intentions). Pro tip: If you like a smoother sauce, blitz it briefly with an immersion blender after removing the bay leaf.
Use a meat thermometer to hit the exact doneness you prefer. Timing: Low-and-slow creates tenderness.
Check the pork around the later half of the cooking window to avoid overcooking. Resting the pork is non-negotiable; it keeps the juices where they belong — inside the meat, not on your cutting board.
Leftover love: Slice the leftover pork thin and toss it into a sandwich with a smear of mustard and warmed sauce. Leftovers are basically a planned encore.
