Ingredients
- 1 (2–3 lb) pork loin
- 2 tbsp olive oil
- 8 oz cremini mushroom, sliced
- 1 medium onion, thinly sliced
- 2 garlic cloves, minced
- 1 cup Marsala wine
- 1 cup low-sodium chicken broth
- 2 tbsp soy sauce
- 2 tbsp Dijon mustard
- 1 tbsp Worcestershire sauce
- 2 tsp dried thyme
- 1 bay leaf
- 2 tbsp cornstarch
- 2 tbsp cold water
- 2 tbsp unsalted butter
- Salt and black pepper, to taste
- 1 tbsp fresh parsley, chopped (for garnish)
Instructions
- Pat the pork loin dry and season it all over with salt and black pepper like you mean it.
- Heat the skillet over medium-high heat and add the olive oil until it shimmers.
- Sear the pork loin on all sides until browned for a couple of minutes per side to lock in flavor.
- Transfer the seared pork loin to the slow cooker and use kitchen twine to tie it if you want a neat roast that slices like a pro.
- Add the sliced mushroom and sliced onion to the hot skillet and sauté until they release their juices and start to brown.
- Stir the garlic into the skillet and cook until fragrant, which happens fast so don’t wander off.
- Pour the Marsala wine into the skillet to deglaze, scraping up the browned bits from the bottom with a wooden spoon.
- Add the chicken broth, soy sauce, Dijon, Worcestershire, dried thyme, and bay leaf to the skillet and bring the mixture to a gentle simmer to marry the flavors.
- Pour the wine-and-broth mixture over the pork loin in the slow cooker, making sure the liquid comes partway up the roast.
- Cover and cook on low until the pork reaches a safe, tendertemperature—check with a meat thermometer for doneness.
- When the pork is almost done, remove it to a serving platter and tent it with foil so it can rest while you make the sauce.
- Use the slotted spoon to transfer the mushroom and onion from the slow cooker into the skillet or a saucepan.
- Whisk the cornstarch with cold water in the mixing bowl to make a smooth slurry and set it aside.
- Bring the remaining liquid in the slow cooker to a simmer by transferring a portion into the saucepan with the mushroom and onion.
- Whisk the slurry into the simmering sauce and cook until it thickens into a glossy, spoon-coating consistency.
- Swirl in the butter off the heat until the sauce is silky and taste to adjust seasoning with salt and pepper.
- Slice the pork loin into medallions and arrange them on the platter.
- Spoon the mushroom–Marsala sauce over the sliced pork and sprinkle with chopped parsley before serving.
Good to Know
Tip: Searing the pork loin first is optional, but that browned crust adds big flavor, and that’s why I always do it. Variation: Swap Marsala for dry sherry or a rich white wine if you prefer; the character will change slightly but still be delicious.
Thickening trick: If the sauce doesn’t get thick enough, mash a piece of the mushroom into the pan or add a touch more cornstarch mixed with cold water and simmer a minute longer. Serving suggestion: Serve over mashed potato, creamy polenta, or buttered egg noodle for maximum sauce-sopping enjoyment.
Make-ahead: You can cook the pork loin a day ahead, refrigerate it with the sauce, and reheat gently; flavors actually deepen, which feels like magic but is just good planning. Safety note: Use the meat thermometer to ensure the internal temperature reaches a safe level for pork; resting will carry over heat and keep juices locked in.
Final pep talk: This recipe is slow-cooker friendly and party-approved, so invite someone over, pretend it took all day, and accept every compliment with the dignity of a chef who totally planned this.
