Slow cooking transforms affordable pork loin into a melt-in-your-mouth centerpiece. The potatoes and carrots absorb the savory herb broth, becoming rich and tender alongside the meat.

This dish proves that restaurant-quality results are possible at home with simple ingredients and time. Serve it straight from the cooker for an effortless, satisfying meal.
Ingredients for pork loin roast with potatoes and carrots slow cooker
Pantry staples meet slow cooker magic for this herb-kissed pork dinner.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin 🥩 | 2 lb | Boneless, trimmed of excess fat |
| Yukon Gold Potatoes 🥔 | 1 ½ lb | Cut into 2-inch chunks |
| Carrots 🥕 | 4 whole | Peeled, cut into 2-inch pieces |
| Onion 🧅 | 1 whole | Yellow or sweet, quartered |
| Garlic Cloves 🧄 | 4 cloves | Smashed, peeled |
| Dried Rosemary 🌿 | 1 tbsp | Crushed between fingers |
| Dried Thyme 🍃 | 1 tbsp | Rubbed to release oils |
| Chicken Broth 🥣 | 1 cup | Low-sodium preferred |
| Olive Oil 🫒 | 2 tbsp | Extra-virgin for searing |
| Kosher Salt 🧂 | 1 ½ tsp | Diamond Crystal brand preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly cracked for best flavor |
| Dijon Mustard 🟡 | 1 tbsp | Whole-grain style works too |
| Apple Cider Vinegar 🍏 | 1 tbsp | Balances richness of pork |
The pork loin is the star here. Costco or Sam’s Club have great prices on large cuts—buy a 4-5 lb roast and freeze half for next time. Look for even marbling (not too fatty, not too lean) for that melt-in-your-mouth texture. The Smoky Pig always used Yukon Golds for their buttery texture, but red potatoes work too (just don’t peel them). Fresh herbs? Save them for garnish—dried hold up better in the slow cooker.
No pork loin? Pork shoulder actually gets more tender, but it’s fattier. Swap the broth for vegetable broth if that’s what you’ve got. Out of Dijon? Regular mustard plus a pinch of sugar mimics the tang. The vinegar can be white wine or even lemon juice—whatever brightens the pot. Fresh rosemary and thyme at triple the amount work if you’ve got herbs growing (just add them later).
Leftovers keep 4-5 days in the fridge, taste even better reheated. Freeze portions for up to 3 months—perfect for meal prep. The potatoes soak up broth like sponges, so store them submerged to keep moist.

Step-by-step instructions for pork loin roast with potatoes and carrots in a slow cooker
Here's the method. Straightforward, tested, works every time.
Sear the Pork Loin for Depth of Flavor
Pat the 2 lb Pork Loin dry with paper towels. This ensures a good sear rather than steaming. Season generously with 1.5 tsp Kosher Salt and 1 tsp Black Pepper, pressing the seasoning into the meat so it adheres.
Heat 2 tbsp Olive Oil in a large skillet over medium-high heat until shimmering. Sear the pork loin on all sides for 2-3 minutes per side until deeply browned. You're looking for a rich, golden crust—this adds incredible flavor to the final dish.
Layer Vegetables and Aromatics in the Slow Cooker
Place the 1.5 lb Yukon Gold Potatoes (cut into 2-inch chunks) at the bottom of the slow cooker. Add the 4 whole Carrots (peeled and cut into 2-inch pieces), 1 whole Onion (quarterd), and 4 cloves Garlic Cloves (smashed and peeled).
Sprinkle 1 tbsp Dried Rosemary (crushed between your fingers) and 1 tbsp Dried Thyme (rubbed to release the oils) over the vegetables. These herbs will infuse everything with an aromatic depth as it cooks.
Add Liquid and Pork to the Slow Cooker
In a small bowl, whisk together 1 cup Chicken Broth, 1 tbsp Dijon Mustard, and 1 tbsp Apple Cider Vinegar. Pour this mixture over the vegetables in the slow cooker.
Place the seared pork loin on top of the vegetables, ensuring it’s nestled in but not submerged. The liquid should come about halfway up the pork. Cover and cook on low heat for 6-7 hours or on high heat for 3-4 hours.
Check for Tenderness and Serve
The pork is done when it reaches an internal temperature of 145°F and pulls apart easily with a fork. The vegetables should be tender but still hold their shape—not mushy.
Transfer the pork loin to a cutting board and let it rest for 10 minutes before slicing. Serve the sliced pork with the potatoes and carrots, spooning the cooking liquid over the top for extra flavor. The pork will be fork-tender, and the vegetables will have absorbed all the herb-infused goodness.
Pro Tips For Making Pork Loin Roast With Potatoes And Carrots Slow Cooker
- Sear the Pork: I learned this the hard way—browning the pork loin in a hot pan before it hits the slow cooker adds depth the dish would otherwise lack. About 2-3 minutes per side in a little oil does the trick.
- Cut Even Chunks: Yukon Golds and carrots cook at different rates, so slice them into 1.5-inch pieces for even doneness. Any bigger and you’ll end up with undercooked potatoes or mushy carrots.
- Skip the Liquid: Pork loin releases plenty of juices, and adding broth or water just dilutes the flavor. Trust the process—your veggies will steam perfectly in the meat’s natural moisture.
- Use a Meat Thermometer: After burning three batches, I finally figured out that guessing doneness is a gamble. Pull the pork at 145°F, then let it rest 10 minutes before slicing.
Storing and reheating this recipe
Refrigerator Storage
Let the pork loin cool to room temperature (about 2 hours max) before storing. Transfer to airtight containers with the juices and vegetables—I use glass Pyrex for easy reheating. This keeps in the fridge for 4-5 days. The flavors deepen overnight, making leftovers even better. ❄️
Freezer Storage
For longer storage, portion the pork with vegetables and broth into freezer bags. Squeeze out excess air and freeze flat for up to 3 months. I recommend quart-size bags for individual meals. Label with the date—trust me, you'll forget otherwise.
Stovetop Reheating
Gently reheat portions in a saucepan with a splash of chicken broth over medium-low heat for 10-15 minutes. This prevents drying out. Stir occasionally to distribute the juices evenly. The potatoes will soak up the liquid like a sponge.
Microwave Method
For quick meals, place portions in a microwave-safe dish with a damp paper towel. Heat on 70% power for 2-3 minutes, stir, then heat in 1-minute intervals until reaching 165°F. Add a splash of water if needed.
Oven Reheating
Preheat oven to 300°F and place portions in a covered dish with ¼ cup broth. Bake for 20-25 minutes until heated through. This method works best for larger portions. 🔥

Frequently asked questions
Can I use a different cut of pork?
Yes, pork shoulder works but has more fat. It becomes incredibly tender with 8-9 hours on low. Loin is leaner and cooks faster, so adjust time accordingly.
Do I need to sear the pork first?
Highly recommended! Searing adds deep flavor and color. Skip it only if short on time, but expect less rich results. Use medium-high heat for best crust.
Why are my potatoes mushy?
They likely cooked too long. Cut them into 2-inch chunks and place at the bottom. For firmer texture, add them 2 hours before serving instead of at the start.
Can I add other vegetables?
Try parsnips, celery, or Brussels sprouts. Just cut them uniformly and add denser veggies first. Avoid delicate ones like zucchini—they turn to mush.
