This slow cooker method transforms pork tenderloin into a tender, herb-infused centerpiece with minimal effort. I developed this recipe to maximize flavor while keeping the process simple and reliable.
The key is layering vegetables beneath the pork, allowing them to absorb the juices as everything cooks low and slow. A blend of fresh herbs and garlic ensures every bite carries depth without requiring constant attention.
By the end of the cooking time, you’ll have fall-apart pork surrounded by perfectly softened vegetables, all infused with the same aromatic seasoning. It’s a complete meal that practically prepares itself.
Ideal for busy weeknights or relaxed weekend dinners, this dish delivers consistent results with hands-off convenience.

The pork tenderloin should be fresh and uniformly thick for even cooking. Whole Foods or Costco typically carry high-quality cuts with good marbling. Look for pieces around 1.5 lb—smaller ones dry out, larger ones need adjustment. The Yukon Gold potatoes are ideal for their buttery texture (red potatoes work too). Fresh rosemary and thyme are non-negotiable here; dried won’t give the same aromatic depth.
No fresh herbs? Dried rosemary and thyme at one-third the amount work in a pinch, but fresh is strongly recommended. Chicken broth can be swapped for vegetable broth (use low-sodium to control seasoning). If you’re out of Dijon, whole-grain mustard adds a nice texture. The carrots and onions are flexible—use what you have (parsnips or sweet potatoes are great alternatives).
Store the pork in its original packaging in the fridge for up to 3 days before cooking. Fresh herbs last 1 week wrapped in damp paper towels. Leftovers keep 4-5 days in the fridge or freeze for 3 months—perfect for meal prep.

Step-by-Step Instructions for Pork Tenderloin Slow Cooker With Vegetables
Here’s the method. Straightforward, tested, works every time.
Step 1: Sear the Pork Tenderloin for Depth of Flavor
Heat the 2 tbsp olive oil in a large skillet over medium-high heat until it shimmers but doesn’t smoke. Pat the 1.5 lb pork tenderloin dry with paper towels and season evenly with the 1 tsp salt and 0.5 tsp black pepper.
Sear the pork on all sides for 2-3 minutes per side until deep golden brown. This creates a flavorful crust and locks in juices. Don’t rush this process—proper browning develops the fond that will enrich the final dish.
Step 2: Prepare the Herb and Vegetable Base
While the pork sears, arrange the 1.5 lb Yukon Gold potatoes (cut into 1-inch chunks), 4 whole carrots (peeled and sliced into sticks), and 1 whole yellow onion (thinly sliced into wedges) in the slow cooker. Scatter the 6 cloves garlic cloves (minced), chopped leaves from the 2 whole fresh rosemary sprigs and 4 whole fresh thyme sprigs, and the 2 whole dried bay leaves over the vegetables.
Pour the 1 cup chicken broth into the slow cooker. The liquid should come about halfway up the vegetables. This ensures even cooking and prevents drying out during the long, slow process.
Step 3: Combine and Slow Cook to Perfection
Place the seared pork tenderloin on top of the vegetables in the slow cooker. In a small bowl, whisk together the 1 tbsp Dijon mustard with 1 tablespoon of the chicken broth from the slow cooker. Brush this mixture evenly over the pork.
Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours. The pork is done when it reaches an internal temperature of 145°F and is tender when pierced with a fork. The vegetables should be soft and infused with the herb flavors.
Step 4: Rest and Serve
Carefully remove the pork tenderloin from the slow cooker and transfer it to a cutting board. Tent loosely with foil and let it rest for 10 minutes before slicing. This allows the juices to redistribute, ensuring each slice is moist and tender.
Discard the dried bay leaves from the slow cooker. Serve the sliced pork over the herb-infused vegetables, spooning some of the cooking liquid over the top for added flavor. The result should be a harmonious blend of tender pork and perfectly cooked vegetables with a rich, aromatic sauce.
Pro Tips For Making Pork Tenderloin Recipe Slow Cooker With Vegetables
- Sear First: I learned this the hard way—browning the pork tenderloin in a hot pan for 2-3 minutes per side before it goes in the slow cooker locks in juices and adds depth. Skip this and the flavor falls flat.
- Cut Potatoes Evenly: Yukon Golds cook faster than you think, so slice them into 1.5-inch chunks. Anything bigger and you’ll have raw centers by the time the pork is done.
- Skip the Overcrowding: Resist the urge to dump everything in at once—layer the carrots and potatoes under the pork, not piled on top, or they’ll steam instead of roast.
- Use Fresh Garlic: sounds weird, but it works: crush the garlic cloves lightly before adding them whole, so their flavor infuses the broth without turning bitter. Pre-minced jarred garlic just doesn’t cut it here.
Wine and Beer Pairings for These Flavors
White Wine Pairings
A crisp Sauvignon Blanc from New Zealand cuts through the richness beautifully. Its bright acidity and citrus notes complement the herb-infused pork and vegetables. I love Kim Crawford for its consistent quality at $15-20. 🍷
Red Wine Options
For red wine lovers, a light Pinot Noir from Oregon works wonderfully. Try Meiomi—its red fruit flavors and silky tannins won’t overpower the dish. Serve slightly chilled at 60°F for best results.
Craft Beer Choices
An American Amber Ale like Fat Tire offers caramel notes that pair well with the seared pork. The moderate hop bitterness balances the dish’s savory elements. I find 12 oz bottles perfect for individual servings. 🍺
Non-Alcoholic Pairings
For a non-alcoholic option, try sparkling apple cider—its effervescence and sweetness complement the herbs. I love Martinelli’s Gold for its clean, crisp finish. Serve well-chilled at 40°F.
Cider Pairings
A dry hard cider like Angry Orchard Traditional Dry adds a refreshing contrast. The slight tartness cuts through the pork’s richness while allowing the herbs to shine. Serve in a chilled glass for best results.

Frequently Asked Questions
Can I skip searing the pork first?
You can, but searing adds depth of flavor. The 2-3 minutes per side creates a crust that enhances the final dish significantly. Skipping may result in less complex taste.
What if my pork is larger than 1.5 lb?
Adjust cooking time: add 30-45 minutes for each additional half-pound on low. Always check internal temp reaches 145°F before serving. Overcooking dries it out, so monitor closely.
Can I use frozen vegetables instead?
Yes, but thaw and drain them first to avoid excess moisture. Fresh is ideal for texture, but frozen works in a pinch. The herbs will still infuse beautifully during the 6-7 hours cook time.
How do I prevent the vegetables from getting mushy?
Cut them into uniform 1-inch chunks and place under the pork. The pork’s weight helps them cook evenly without turning to mush. Also avoid overfilling the slow cooker.
