The Ingredients

This recipe uses simple, affordable ingredients that come together beautifully.

1 whole pork tenderloin (about 1 to 1½ pounds) – For tender, juicy pork.
1½ pounds baby gold potatoes – For buttery, flavorful potatoes.
¼ cup honey – For sweetness and a beautiful glaze.
¼ cup Dijon mustard – For tang and depth.
2 teaspoons minced garlic – For savory, aromatic punch.

Step-by-Step Instructions

Step 1: Layer the Potatoes

Wash and dry the baby gold potatoes, then spread them in an even layer in the bottom of a white slow cooker insert.

Pro Tip: An even layer ensures the potatoes cook evenly and soak up the glaze.

Step 2: Add the Pork Tenderloin

Set the whole pork tenderloin on top of the potatoes so the potatoes act like a rack and keep the meat lifted up a bit from the bottom.

Pro Tip: The potatoes act as a natural rack, keeping the pork from sitting in the juices and becoming soggy.

Step 3: Make the Honey Mustard Glaze

In a small bowl, stir together the honey, Dijon mustard, and minced garlic until smooth, then spoon and spread the mixture over the top of the tenderloin.

Pro Tip: Spread the glaze evenly over the pork for maximum flavor.

Step 4: Cook Low and Slow

Cover and cook on low for 3 to 4 hours, checking near the 3-hour mark, until the pork reaches 145°F in the thickest part and the potatoes are tender.

Pro Tip: Don’t overcook the pork—it can dry out quickly. Check at the 3-hour mark.

Step 5: Rest the Pork

Transfer the tenderloin to a cutting board and let it rest for 10 minutes before slicing. Stir the potatoes gently in the cooking juices.

Pro Tip: Resting the pork allows the juices to redistribute, keeping it juicy and tender.

Step 6: Slice and Serve

Slice the pork and serve it with the potatoes, spooning some of the juices from the slow cooker over the top.

Pro Tip: Serve with a simple green salad or roasted vegetables for a complete meal.
