Equipment: Nice-to-haves
- Skillet (for searing, optional)
- Instant-read thermometer (optional but very helpful)
- Small bowl for cornstarch slurry
- Serving platter
Ingredients
- 1 to 1.5 lb pork tenderloin
- 2 tbsp balsamic vinegar
- 2 tbsp olive oil
- 2 clove garlic, minced
- 1 tbsp Dijon mustard
- 1 tbsp brown sugar
- 1 tsp dried rosemary
- 1 tsp dried thyme
- 1 bay leaf
- 1/2 cup chicken broth
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp cornstarch
- 1 tbsp water
- 1 small onion, sliced (optional, for a flavor bed)
- 1 tbsp fresh parsley, chopped (for garnish)
Instructions
- Trim any silver skin from the pork tenderloin and pat it dry with a paper towel to help the marinade stick.
- In a mixing bowl combine balsamic vinegar, olive oil, minced garlic, Dijon mustard, brown sugar, dried rosemary, dried thyme, salt, and pepper to make the marinade.
- If using the skillet, heat it over medium-high heat and sear the tenderloin on all sides until golden to add flavor; otherwise skip this step and carry on—slow cooking will still make it juicy.
- Place the sliced onion in the bottom of the slow cooker to make a little aromatic bed, if using.
- Use tongs to coat the pork tenderloin in the marinade, pressing some of the mixture under the surface where possible.
- Nestle the marinated pork onto the onion bed in the slow cooker and pour any leftover marinade over the top.
- Add the chicken broth and tuck the bay leaf beside the pork so it can mingle without getting bossy.
- Cover and cook on low until the pork is tender and reaches a safe internal temperature, checking with an instant-read thermometer if you have one.
- When the pork is done, remove it carefully to a cutting board and let it rest so the juices redistribute—this step makes it juicy, not tragic.
- Skim any excess fat from the cooking liquid, then pour the liquid into a saucepan and bring it to a gentle simmer to concentrate the flavor.
- Mix cornstarch and water in a small bowl to make a slurry, then whisk it into the simmering cooking liquid to thicken to a glossy glaze.
- Slice the rested pork tenderloin against the grain, arrange on a serving platter, and spoon the balsamic herb glaze over the top.
- Scatter chopped fresh parsley for color and a herbaceous finish, and serve with your favorite side for applause, not awkward silence.
Good to Know
Tip: Searing is optional but worth it if you want deeper flavor and a prettier crust. No skillet?
No problem—skip it and still celebrate. Timing: Cooking on low is kinder to the tenderloin and keeps it juicy; aim for a few hours depending on size.
Use an instant-read thermometer and pull the meat at the recommended safe temperature for pork, then let it rest. Sauce tricks: If your glaze is too thin, simmer a little longer or add a tiny bit more cornstarch slurry.
If it’s too tangy, a pinch of brown sugar will mellow it out. That’s why I always keep a sugar pinch and an emergency spoon handy.
Variations: Swap dried herbs for fresh if you have them—fresh thyme sprig or a fresh rosemary sprig tucked under the meat will make you look fancy. For a spicy twist, add a dash of red pepper flakes to the marinade.
Serving suggestion: Serve sliced pork over mashed potato, creamy polenta, or a mound of roasted vegetable for a complete plate. Leftovers (yes, that rare unicorn) also make excellent sandwiches.
Storage: Keep leftover pork in an airtight container for up to three days. Reheat gently and spoon extra glaze back over the slices to revive the juiciness.
Final note: This recipe turns a single pork tenderloin into a star with minimal effort. You get a tangy, herby sauce, a tender center, and bragging rights when someone asks how you did it.
Smile, nod, and accept compliments.
