Ingredients
- 1 pork tenderloin (about 1 to 1.5 lb)
- 1 tablespoon olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1 teaspoon dried thyme
- 1/2 teaspoon smoked paprika
- 2 clove garlic, minced
- 1 tablespoon Dijon mustard
- 1/2 cup blackberry preserves
- 1/4 cup balsamic vinegar
- 1/4 cup chicken broth
- 1 tablespoon soy sauce
- 1 teaspoon cornstarch
- 1 tablespoon cold water
- 1 tablespoon butter (optional, for shine)
- 1 tablespoon chopped parsley for garnish
Instructions
- Pat the pork tenderloin dry and trim any silver skin from the surface.
- Season the pork all over with salt, black pepper, dried thyme, and smoked paprika.
- Heat the skillet over medium-high and add the olive oil until it shimmers.
- Sear the pork on all sides until golden brown, using the tongs to rotate—it should look proud and caramelized.
- Transfer the seared pork into the crockpot and tuck it into the middle.
- In the same skillet, add the minced garlic and cook briefly until fragrant, stirring with the spoon.
- Add the blackberry preserves, balsamic vinegar, Dijon mustard, chicken broth, and soy sauce to the skillet and stir until combined.
- Bring the glaze mixture to a gentle simmer to loosen the preserves and meld the flavors.
- Pour the glaze over the pork in the crockpot, coating it evenly.
- Cover and cook the pork on low until tender and an internal temperature reads done on a thermometer, or cook on high for a shorter time.
- When the pork is ready, transfer it to a cutting board and tent it to rest.
- Pour the cooking juices and glaze from the crockpot back into the skillet and bring to a simmer.
- Mix the cornstarch with the cold water to make a slurry, then whisk it into the simmering glaze until thickened to a glossy sauce.
- Stir in the butter if using, for extra shine, then taste and adjust seasoning if needed.
- Slice the rested pork and spoon the blackberry glaze over each slice before plating.
- Garnish with chopped parsley and serve immediately with your favorite side.
Good to Know
Cooking notes and tasty ideas to make this blackberry glaze pork shine:
Timing and temperature: Low-and-slow is the slow cooker’s love language. Cooking on low gives the juiciest result.
If you’re short on time, use high but check early. The safe internal temp for the tenderloin is the best guide—use a meat thermometer and aim for done that still looks rosy and juicy.
Searing matters: That quick sear in the skillet adds flavor and color. It’s not mandatory, but it’s dramatic.
Think of it as the outfit change before the slow-cook party. Thickening the glaze: If the sauce from the crockpot looks thin, the cornstarch slurry will save the day.
Whisk it into a simmering glaze slowly until it coats the back of a spoon. If you prefer a super-smooth sauce, blitz it with the immersion blender.
Fresh versus jarred berry: No blackberry preserves? No problem.
Use fresh blackberry mashed with a little sugar and a splash of balsamic, then strain seeds if you like a velvet finish. That’s why the recipe includes both preserves and vinegar—to deepen the fruit flavor.
Flavor swaps and variations: Swap rosemary or sage for thyme if you’re feeling herbal. Use apricot or cherry preserves for a different sweet-tart vibe.
For a spicy kick, add a pinch of red pepper flakes to the glaze. Gluten and allergy notes: The recipe is almost naturally gluten-free if you use a gluten-free soy sauce or tamari.
That’s flexible dinner planning, not a puzzle. Make-ahead and leftovers: You can assemble the glaze and refrigerate it a day ahead.
Leftover sliced pork loves salads, sandwiches, or a quick stir-fry. Store in an airtight container for up to four days, or freeze for up to three months.
Serving suggestions: Pair the pork with mashed potato, roasted root vegetable, or a bright salad to balance the sweetness. A simple grain like quinoa or couscous is also crowd-pleasing.
Presentation tip: Let the meat rest before slicing so juices don’t escape. Brush the glossy glaze over the slices right before serving for that restaurant ‘I planned this’ look.
Little chef hacks: If you want the glaze thicker without cornstarch, reduce it slowly on the stovetop until syrupy. Want extra tang?
Add a tiny squeeze of lemon or a splash more vinegar at the end. Final thought: This dish is proof that a crockpot can produce something elegant.
Minimal fuss, maximum flavor, and an excuse to tell friends you “marinated it for hours” (which is partly true). Now go make dinner and act like you had all the time in the world.
