Equipment: Nice-to-haves
- Skillet (for searing)
- Meat thermometer
- Whisk
- Small saucepan
- Serving platter

Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb)
- 1 cup whole cranberry sauce
- 1/2 cup chicken broth
- 2 tablespoons balsamic vinegar
- 1 tablespoon brown sugar
- 1 clove garlic, minced
- 1 small onion, thinly sliced
- 1 sprig fresh rosemary, chopped
- 1 teaspoon Dijon mustard
- 1/2 teaspoon salt
- 1/4 teaspoon black pepper
- 1 tablespoon olive oil (for optional searing)
- 1 teaspoon cornstarch (optional thickener)
- 1 tablespoon cold water (for slurry)

Instructions
- Pat the pork tenderloin dry and trim any silver skin or loose bits so it cooks evenly and looks sharp.
- Season the tenderloin with salt, black pepper, chopped rosemary, and smear the Dijon mustard over the surface for a flavor anchor.
- If you want extra color and flavor, heat a skillet with olive oil and quickly sear the tenderloin on all sides until browned; this step is optional but delightful.
- Place the tenderloin into the slow cooker and arrange the sliced onion around it like it’s camping with a single, tasty guest.
- In a mixing bowl combine the cranberry sauce, chicken broth, balsamic vinegar, brown sugar, and minced garlic until smooth-ish; it’s okay if bits of cranberry still show—texture is personality.
- Pour the cranberry mixture over the tenderloin, making sure the sauce covers the meat and gives it a cozy, tangy blanket.
- Set the slow cooker to low for several hours or to high for a shorter time, and cook until the pork reaches the safe internal temperature and is tender to the touch.
- Check the pork with a meat thermometer toward the end of cooking so you don’t guess like a game show contestant.
- When the pork is done, carefully remove it to a plate and tent with foil to rest while you finish the sauce.
- If the sauce needs thickening, pour the cooking liquid into a small saucepan and bring to a simmer.
- Whisk the cornstarch into the cold water to make a slurry, then slowly whisk the slurry into the simmering sauce until it thickens to a glossy consistency.
- Slice the pork tenderloin into medallions against the grain for maximum tenderness and stack them on your serving platter.
- Spoon the cranberry sauce over the sliced pork and garnish with a little extra chopped rosemary if you’re feeling fancy.
- Serve hot with your choice of sides and try not to hog the gravy spoon—temptation is real.

Good to Know
Tip: Resting the pork before slicing keeps the juices inside and your guests happy instead of sticky-handed. Variation: Swap the balsamic vinegar for apple cider vinegar for a brighter tang, or stir in a pinch of ground cinnamon for a warm holiday vibe.
Make-ahead: You can assemble the slow cooker the night before, refrigerate, and cook the next day; just bring the pork closer to room temperature before starting. Serving suggestion: Slice and serve the pork over mashed potato, creamy polenta, or buttered egg noodles to soak up that cranberry magic.
Vegetarian twist: Roast a large portobello mushroom cap while the sauce simmers for a mushroom ‘steak’ that plays nice with the cranberry glaze. Storage: Leftover sliced pork keeps well in the fridge for up to four days; reheat gently and add a splash of broth if the sauce has tightened up.
That’s why this recipe is a winner: minimal fuss, big flavor, and the kind of leftovers that make lunch exciting. Final note: If you skip the sear, the dish still sings—searing just adds swagger.
Enjoy the slow-cooked glory and try not to eat the sauce straight from the saucepan (no promises accepted).
