Pork Loin Roast Crock Pot Recipe Potatoes: Hands-Off Meal With Golden Spuds

This crock pot method delivers a tender pork loin with golden potatoes every time, using minimal effort for maximum flavor.

I developed this technique to ensure the meat stays juicy while the potatoes develop a rich, buttery texture without turning mushy.

The slow cooker does all the work, allowing the pork to absorb the seasonings and the potatoes to soak up the savory juices.

You’ll end up with a complete meal that’s ready when you walk through the door, with perfectly cooked pork and spuds in one pot.

Ingredients for Pork Loin Roast Crock Pot Recipe Potatoes

Simple ingredients transform into a complete meal with tender pork and golden potatoes.

The pork loin should have good marbling—Costco or Whole Foods have reliable options. Yukon Golds are ideal for their buttery texture (avoid waxy red potatoes). Look for firm, unblemished spuds that feel heavy for their size. For the broth, Swanson or Pacific Foods offer quality low-sodium versions that won’t overpower the dish.

No Dijon? Whole-grain mustard at half the amount works. Short on fresh parsley? Dried parsley at one-third the amount is fine. Chicken broth can be swapped for vegetable broth. If you’re missing thyme or rosemary, poultry seasoning at the same amount covers both. The butter is key for the potatoes—don’t skip it (or use olive oil in a pinch).

Leftovers keep 4-5 days in the fridge. Reheat gently to avoid drying the pork. Freeze for up to 3 months in airtight containers. The potatoes absorb flavors even more overnight—this tastes better the next day.

Step-by-Step Instructions for Pork Loin Roast Crock Pot Recipe Potatoes

This method delivers tender pork and golden potatoes with minimal effort.

Step 1: Sear and Season the Pork Loin

Heat the 2 tbsp Olive Oil in a large skillet over medium-high heat. Pat the 2 lb Pork Loin dry with paper towels, then season generously with 1 tsp Salt and 1 tsp Black Pepper, pressing the seasoning into all sides.

Sear the pork loin on all sides for 2-3 minutes per side until deep golden brown. This creates a flavorful crust and locks in juices. Transfer the seared pork to your crock pot, placing it in the center.

Step 2: Prepare the Potato and Aromatic Base

In the crock pot, arrange the 2 lb Yukon Gold Potatoes (peeled and quartered) around the pork loin. Add the 1 whole Onion (sliced) and 4 cloves Garlic Cloves (minced) evenly over the potatoes and pork.

Sprinkle the 1 tsp Dried Thyme and 1 tsp Dried Rosemary over everything, along with the remaining 0.5 tsp Salt. Pour the 1 cup Chicken Broth into the crock pot, ensuring the liquid pools at the bottom without submerging the pork.

Step 3: Add Flavor Boosters and Slow Cook

In a small bowl, whisk together the 2 tbsp Dijon Mustard with 2 tbsp Butter until smooth. Spoon this mixture over the top of the pork loin, spreading it evenly to create a tangy, buttery glaze.

Cover the crock pot and cook on low heat for 6-7 hours or on high heat for 3-4 hours. The dish is done when the pork reaches an internal temperature of 145°F and the potatoes are fork-tender with golden edges.

Step 4: Rest and Garnish Before Serving

Once cooking is complete, transfer the pork loin to a cutting board and let it rest for 10 minutes. This allows the juices to redistribute, ensuring moist, tender slices. Keep the crock pot covered to retain heat in the potatoes.

Slice the pork loin against the grain into ½-inch thick pieces. Arrange the slices over the potatoes in the crock pot. Garnish the entire dish with the 0.25 cup Fresh Parsley (chopped) for a pop of color and freshness.

Troubleshooting Great pork loin roast crock pot recipe potatoes

Pork Too Dry

If your pork loin turns out dry, it likely cooked too long or wasn’t properly seared. Always use a meat thermometer to pull it at 145°F internal temperature. I also recommend not trimming all the fat—it adds moisture during cooking. 🌡️

Potatoes Mushy

Mushy potatoes usually mean they were submerged in liquid or cut too small. Use 2-inch chunks of Yukon Gold and ensure the broth only comes ½ inch up the pot. I learned this the hard way with a batch that turned to mash.

Lack of Flavor

If your dish tastes bland, boost it with more Dijon mustard or garlic next time. Don’t skip searing the pork—it adds a deep, caramelized flavor base. I always taste the broth before adding the potatoes and adjust seasoning then.

Pork Not Tender

Tough pork often results from insufficient cooking time. Stick to low heat for 6-7 hours rather than high heat, which can make the meat stringy. I find that Costco pork loin stays tender when cooked this way.

Uneven Cooking

If some potatoes are undercooked, arrange them around the edges where the heat is most direct. Also, avoid overcrowding the crock pot—leave 1 inch between pieces. This ensures even cooking throughout. 💡

Sauce Too Thin

For a thicker sauce, remove the pork and potatoes, then reduce the liquid on the stovetop for 5-10 minutes. I sometimes mix in 1 tsp cornstarch with water for a quick fix. The flavors will be more concentrated too.
