- Tongs
- Meat thermometer
- Wooden spoon
- Slotted spoon
- Small bowl (for slurry)
Ingredients
- 1 pork tenderloin (about 1.5 lb), trimmed
- 8 oz wild mushroom mix, sliced
- 1 medium onion, thinly sliced
- 3 clove garlic, minced
- 1 cup low-sodium chicken broth
- 1/2 cup dry white wine (or additional broth)
- 2 tbsp Dijon mustard
- 2 tbsp soy sauce (or tamari)
- 2 tbsp olive oil
- 2 tsp fresh thyme leaves (or 1 tsp dried thyme)
- 1 bay leaf
- 1 tbsp cornstarch
- 2 tbsp cold water
- Salt, to taste
- Black pepper, to taste
- 2 tbsp unsalted butter (optional, for finish)
- 1 tbsp fresh parsley, chopped, for garnish
Instructions
- Pat the pork tenderloin dry and season all over with salt and pepper like you mean it.
- If using a skillet, heat oil until shimmering and sear the pork on all sides until golden; this step is optional but adds great flavor.
- Place the sliced onion in the bottom of the slow cooker to form a cozy bed for the meat.
- Nestle the pork tenderloin on top of the onion bed in the slow cooker.
- Scatter the sliced wild mushroom mix and minced garlic around and on top of the pork.
- In a mixing bowl, whisk together chicken broth, white wine, Dijon mustard, soy sauce, thyme, and the bay leaf to make a savory sauce.
- Pour the sauce evenly over the pork and mushrooms, then cover the slow cooker.
- Cook on low until the pork reaches a safe temperature and is tender to the touch; the meat should be juicy and yielding.
- When the pork is nearly done, remove it to a plate to rest while you finish the sauce in the slow cooker.
- Mix the cornstarch with cold water in a small bowl to make a smooth slurry.
- Ladle some cooking liquid into a skillet or keep it in the slow cooker and whisk in the cornstarch slurry to thicken the sauce to a glossy finish.
- Stir in the unsalted butter to enrich the sauce and adjust seasoning with additional salt and pepper if needed.
- Slice the pork tenderloin into medallions and return slices to the sauce to warm through briefly.
- Serve the pork medallions topped with wild mushroom sauce and a sprinkle of fresh parsley for brightness.
What Else You Should Know
Tips: Brown the pork if you have a skillet; searing adds color and extra flavor, but skip it if you’re short on time. Timing: Cooking on low is kinder to pork tenderloin; it keeps the meat juicy.
That’s why low-and-slow wins here. Thickening trick: If the sauce is too thin, use the cornstarch slurry and simmer until glossy.
If it’s too thick, thin with a splash of broth. Variations: Swap the white wine for extra broth for an alcohol-free option, or add a splash of heavy cream at the end for a richer sauce.
Try rosemary in place of thyme if that’s what you have on hand. Serving suggestions: Serve with mashed potato, creamy polenta, or buttered egg noodle; the sauce loves to be mopped up.
Add a simple green like steamed broccoli or a crisp salad to balance the richness. Make-ahead and leftovers: The pork keeps well in the fridge for up to three days.
Reheat gently in a skillet with a little broth to prevent drying. Diet notes: Using low-sodium broth and tamari keeps sodium in check.
Wild mushroom brings umami, which helps you use less salt without skimping on flavor. Final note: This recipe is a weeknight hero and weekend show-off.
It lets you walk away while the slow cooker does the heavy lifting. Enjoy the applause — you earned it with almost no sweat.
