The pork is the star here. Look for tenderloin with even thickness for the most consistent cooking—avoid pieces that taper too much. Costco has great options if you’re feeding a crowd, but any grocery store will have what you need. Potatoes and carrots should be fresh and firm (no sprouting or soft spots). I always grab a few extra carrots—they’re great for snacking while dinner cooks.

Need to swap anything? Sweet potatoes work just as well as russets. No fresh garlic? Garlic powder at one-third the amount does the trick. Out of chicken broth? Vegetable broth is a fine substitute. If you don’t have Dijon, regular mustard works in a pinch (just add a pinch of sugar to balance the acidity).

Everything goes straight into the slow cooker, so prep can be done the night before. Keeps in the fridge for 3-4 days—it’s even better the next day. Freeze leftovers for up to 3 months if you somehow have any.

Step-by-Step Instructions for Pork Tenderloin With Potatoes and Carrots

Here’s how I make this meal with minimal effort and maximum flavor.

Step 1: Season the Pork Tenderloin

Pat the 1.5 lb Pork Tenderloin dry with paper towels to ensure the seasoning sticks. I trim any excess fat first—it makes for a cleaner dish. Rub the pork with the 1.5 tsp Salt, 1 tsp Black Pepper, 1 tsp Dried Thyme, and 1 tsp Dried Rosemary until evenly coated.

Let it sit for 10 minutes while you prep the vegetables. This brief rest allows the seasoning to penetrate the surface, giving you more flavor in every bite. The pork should look evenly dusted with spices before moving to the next step.

Step 2: Prep and Layer the Vegetables

Peel and cut the 4 whole Carrots into 2-inch chunks, and scrub the 4 whole Russet Potatoes clean before cutting them into 1-inch cubes. I leave the potato skins on for extra texture and nutrients.

Dice the 1 whole Onion and mince the 4 cloves Garlic Cloves. Place the potatoes, carrots, and onion in the bottom of your slow cooker. This creates a bed for the pork, so it doesn’t sit directly on the heat source. The vegetables will absorb all the delicious juices as they cook.

Step 3: Sear and Add the Pork

Heat the 2 tbsp Olive Oil in a skillet over medium-high heat. Sear the pork tenderloin on all sides for 2-3 minutes per side until golden brown. This step locks in the juices and adds a depth of flavor you just can’t get from slow cooking alone.

Transfer the seared pork to the slow cooker, placing it on top of the vegetables. Pour the 0.5 cup Chicken Broth, 1 tbsp Worcestershire Sauce, and 1 tbsp Dijon Mustard over the pork and vegetables. Stir lightly to distribute the liquid evenly.

Step 4: Slow Cook to Tender Perfection

Cover the slow cooker and set it to low heat for 6-7 hours or high heat for 3-4 hours. I prefer low heat—it gives the pork time to become fall-apart tender without drying out. The dish is done when the pork reaches an internal temperature of 145°F and the vegetables are fork-tender.

You’ll know it’s ready when the pork slides apart easily with a fork and the potatoes are soft all the way through. If you’re unsure, give it another 30 minutes on low. The aroma will fill your kitchen, and the meat will practically melt in your mouth.

Step 5: Rest and Serve

Carefully remove the pork from the slow cooker and let it rest on a cutting board for 5-10 minutes. This allows the juices to redistribute, so every slice stays moist and flavorful. Meanwhile, give the vegetables a quick stir to coat them in the cooking liquid.

Slice the pork into ½-inch thick pieces and serve it over the potatoes and carrots. Spoon some of the cooking liquid over the top for extra flavor. The pork should be tender and juicy, with the vegetables perfectly soft and infused with all the savory, herby goodness.

Pro Cooking Tips for Perfect Results

Even Vegetable Cooking

Cut your russet potatoes into 1-inch cubes and carrots into 2-inch chunks for uniform cooking. I place them at the bottom where the liquid pools, ensuring they steam and absorb flavor without turning mushy. 🌡️

Searing Secret

Don’t skip searing the 1.5 lb Pork Tenderloin in 2 tbsp olive oil over medium-high heat. This builds a golden-brown crust that locks in juices and adds incredible depth to the final dish.

Layering Matters

Always place your vegetables first, then the seared pork on top. This keeps the pork elevated so it doesn’t boil in the liquid. I learned this the hard way after a few soggy attempts in my tiny Boston kitchen.

Liquid Balance

Use exactly 0.5 cup Chicken Broth mixed with 1 tbsp Worcestershire Sauce and 1 tbsp Dijon Mustard. Too much liquid and your potatoes will turn to mush; too little and the pork may dry out.

Temperature Check

I always use a meat thermometer to confirm the pork reaches 145°F internal temperature. Pull it at 140°F and let it rest—it’ll coast to perfect doneness while you prep the table.

Resting Time

Let the pork rest for 5-10 minutes before slicing. This is non-negotiable for juicy meat. I tent it loosely with foil to keep it warm while the vegetables soak up the last bits of flavor. 💡
