The first time I put a pork tenderloin into the slow cooker I was nervous but hopeful, I had a tired weeknight, a hungry partner, and a craving for something juicy and low-effort so I tucked the meat into the cooker with a simple honey mustard glaze and left the kitchen to unwind while the Pork Tenderloin Slow Cooker did the gentle work, coming back to a warm, tender roast that sliced beautifully and felt like a tiny cooking victory.

Serves 4
Prep Time: 15 minutes |
Cook Time: 240 minutes |
Total Time: 255 minutes
Ingredients
- 1.5 lb pork tenderloin trimmed
- 1 tbsp olive oil for searing (optional)
- 1 tsp kosher salt
- 1/2 tsp black pepper
- 1 tsp garlic powder
- 1 tsp smoked paprika
- 1/4 cup low sodium soy sauce
- 2 tbsp Dijon mustard
- 2 tbsp honey
- 1/4 cup chicken broth or water
- 1 tbsp apple cider vinegar
- 1 tbsp cornstarch mixed with 2 tbsp cold water for thickening (optional)
- 12 small baby potatoes halved
- 8 oz green beans trimmed
- 2 tbsp chopped fresh parsley for garnish
Instructions
- Season the pork tenderloin evenly with salt, pepper, garlic powder, and smoked paprika, pressing the rub into the meat so it sticks.
- If you have time, heat olive oil in a skillet over medium high heat and sear the tenderloin 1 to 2 minutes per side until lightly browned, this step adds flavor but can be skipped for true hands off cooking.
- In a small bowl whisk together soy sauce, Dijon mustard, honey, chicken broth, and apple cider vinegar and pour half into the slow cooker.
- Place the seared or raw tenderloin in the slow cooker and arrange the halved baby potatoes around it, pour the remaining sauce over the top.
- Cook on low for 3 to 4 hours or until the internal temperature of the thickest part of the pork reaches 145 F and the potatoes are fork tender, avoid overcooking to keep the meat juicy.
- With about 20 minutes left, add the trimmed green beans on top to steam gently and finish cooking.
- Remove the pork to a cutting board and let it rest 5 to 10 minutes, then slice into medallions.
- Pour the cooking juices into a small saucepan and simmer, whisking in the cornstarch slurry if you want a thicker glaze, cook until glossy and slightly reduced, then spoon over the sliced pork and garnish with chopped parsley.
Tips & Tricks
- Pat the pork dry before seasoning so the rub adheres and the meat sears better if you choose to brown it.
- Use a thermometer to avoid overcooking, remove at 145 F and let rest to reach safe doneness without drying.
- If your slow cooker runs hot, check at 3 hours to prevent the tenderloin from drying out.
- Thicken the sauce on the stove instead of in the slow cooker for a glossy finished glaze and better texture.
- Slice against the grain for the most tender bites.
Serving Ideas
- Weeknight family dinner served with the potatoes and green beans for a simple plate.
- Sliced thin for sandwiches on toasted rolls with leftover sauce as a spread.
- Served over mashed potatoes or creamy polenta for a cozy weekend meal.
- Sliced on top of a warm grain salad for a lighter lunch option.
- Presented on a platter for casual entertaining with roasted vegetables around.
