Ingredients
- 1 pork tenderloin (about 1 to 1.25 lb) – trimmed of silver skin
- 1 tablespoon olive oil – for searing
- 1 small onion, sliced – adds sweetness
- 1 garlic clove, minced – because garlic fixes things
- 1 sprig fresh rosemary – or a pinch of dried if you’re lazy
- 1 sprig fresh thyme – pairs perfectly with pork
- 1/2 teaspoon salt – adjust to taste
- 1/4 teaspoon black pepper – freshly ground if possible
- 1 cup low-sodium chicken broth – the base of the gravy
- 1 cup whole berry cranberry sauce – canned is fine and festive
- 1 teaspoon Dijon mustard – for a little tang
- 1 tablespoon brown sugar – balances the tartness
- 1 teaspoon apple cider vinegar – brightens the sauce
- 1 teaspoon cornstarch – for a glossy gravy
- 1 tablespoon unsalted butter – to finish the gravy
- Optional: fresh parsley for garnish – because presentation matters

Instructions
- Trim the pork tenderloin of any silver skin and pat it dry like you mean it.
- Season the pork all over with salt and pepper.
- Heat the skillet over medium-high heat and add the olive oil.
- Sear the pork on all sides until browned for a minute or two per side.
- Transfer the seared pork to the slow cooker and tuck the sliced onion underneath and around it.
- Scatter the minced garlic, rosemary sprig, and thyme sprig into the slow cooker with the pork.
- Spoon the cranberry sauce over the pork so it gets cozy with the herbs.
- Whisk the chicken broth, Dijon mustard, brown sugar, and apple cider vinegar together and pour that mixture over the pork and onions.
- Cover and cook on low until the pork registers a safe internal temperature and feels tender.
- When the pork is done, remove it to a cutting board and tent loosely with foil to rest.
- Use tongs or a slotted spoon to remove the herb sprigs from the slow cooker and discard them.
- Skim off any excess fat from the cooking liquid if you wish, using a spoon.
- Pour the cooking liquid into the skillet and bring it to a gentle simmer over medium heat.
- Mix the cornstarch with a little cold water to make a slurry, then whisk it into the simmering liquid to thicken.
- Whisk in the butter until the sauce is glossy and smooth.
- Taste and adjust seasoning with salt, pepper, or a splash of apple cider vinegar if it needs brightness.
- Slice the pork into medallions and arrange on a serving platter.
- Spoon the herb gravy cranberry sauce over the sliced pork and garnish with chopped parsley if using.
- Serve immediately while the sauce is warm and your guests are impressed.

Good to Know
Tip: Searing the pork first adds flavor and color but you can skip it if you’re short on time. Variation: Swap the whole berry cranberry sauce for a spiced cranberry chutney for extra aroma.
Serving suggestion: Serve with mashed potato or roasted root vegetable and a simple green for balance. Make-ahead note: The pork keeps well refrigerated for a couple of days.
Reheat gently to avoid drying it out. Gluten-free tweak: Use a gluten-free cornstarch and ensure the Dijon is gluten-free.
Cooking time reminder: Slow cooker models vary. Check the pork earlier if your slow cooker runs hot, and use a meat thermometer to confirm doneness.
Leftover idea: Chop the sliced pork and fold into a grain bowl with leftover gravy for lunch magic. Final pro move: If you want an ultra-smooth gravy, pass the sauce through the fine mesh strainer before finishing with butter.
That little step makes you look like you planned this all along.
