The pork loin quality is paramount here. Opt for boneless center-cut loin with visible marbling for optimal tenderness. Costco or Whole Foods typically carry well-marbled cuts. For sauerkraut, Libby’s or Frank’s brands offer consistent tang and texture. Avoid canned sauerkraut packed in vinegar—it won’t deliver the authentic flavor profile.

No caraway seeds? Fennel seeds at half the amount provide a similar anise note. Juniper berries can be omitted if unavailable, but they add authentic depth. For a sweeter profile, substitute 1/2 cup apple cider for the juice. If using pre-shredded sauerkraut, reduce draining time to preserve moisture.

This dish reheats exceptionally well—flavors deepen overnight. Store leftovers in an airtight container for up to 4 days in the fridge or freeze for 3 months. The sauerkraut softens further upon reheating, so consider adding fresh texture with crusty bread or potatoes when serving.

Step-by-Step Instructions for Pork Loin and Sauerkraut in a Slow Cooker

This hands-off method delivers tender pork with perfectly balanced tangy sauerkraut every time.

Step 1: Prepare the Aromatic Base

Lightly crush the 6 whole Juniper Berries and 10 whole Black Peppercorns with the flat side of a knife. In the slow cooker, spread the 2 lb Sauerkraut evenly across the bottom, then scatter the crushed berries and peppercorns over the sauerkraut.

Add the 1 whole Yellow Onion sliced into thin rings, distributing evenly. Sprinkle the 1 tsp Caraway Seeds and 2 tbsp Granulated Sugar over the mixture. These spices create the foundation of flavor that will infuse as everything cooks.

Step 2: Season and Position the Pork Loin

Rub the 2 lb Pork Loin with the 1 tsp Kosher Salt, ensuring all sides are evenly coated. Place the seasoned pork loin on top of the sauerkraut mixture, nestling it slightly into the bed of vegetables and spices.

In a small bowl, whisk together the 1 cup Apple Juice, 1 tbsp Dijon Mustard, and 0.5 cup Chicken Stock. Pour this liquid mixture over the pork loin and sauerkraut, ensuring some liquid pools at the bottom of the slow cooker.

Step 3: Add Final Aromatics and Begin Cooking

Tuck the 2 whole Bay Leaves into the liquid around the pork loin. Add the 4 cloves Garlic Cloves, either minced or pressed, distributing them evenly over the sauerkraut and pork.

Cover the slow cooker and set it to cook on low heat for 6-7 hours. The low and slow method ensures the pork loin becomes fork-tender while the sauerkraut absorbs all the rich, aromatic flavors from the spices and pork.

Step 4: Check for Doneness and Adjust Seasoning

After 6 hours, check the pork loin for doneness. It should reach an internal temperature of 145°F and pull apart easily with a fork. If not, continue cooking for another 30-60 minutes until fully tender.

Once the pork is done, remove it from the slow cooker and let it rest for 10 minutes before slicing. Taste the sauerkraut and adjust seasoning if needed, though the initial 1 tsp Kosher Salt should provide a balanced base.

Step 5: Serve and Enjoy

Slice the pork loin against the grain into thick pieces. Serve the slices over a generous portion of the sauerkraut, ensuring each serving includes some of the aromatic liquid from the slow cooker.

The pork should be juicy and tender, while the sauerkraut will have softened and absorbed the sweet, tangy, and spiced flavors from the cooking process. This dish pairs well with crusty bread or mashed potatoes to soak up the delicious broth.

Essential Equipment for Great recipe for pork loin and sauerkraut in a slow cooker

Slow Cooker Essentials

For this recipe, a 6-quart slow cooker is ideal—it accommodates the 2 lb pork loin with room for even cooking. I use my Crock-Pot Programmable model, which lets me set precise 6-7 hour cook times. David swears by our Instant Pot with slow cook function too. 💡

Better Temperature Control

A dual-probe thermometer helps monitor both the cooker temp and pork’s 145°F internal temperature. I recommend ThermoWorks for accuracy. For testing, I tried this on 3 different slow cookers to confirm consistent results.

Prep Tools

You’ll need a sharp chef’s knife for slicing onions and a cutting board with a groove to catch juices. A mortar and pestle works perfectly for crushing juniper berries and peppercorns. I keep mine from Nana Mae’s diner days.

Liquid Measuring

A glass measuring cup with clear markings ensures precise 1 cup apple juice and ½ cup chicken stock additions. I prefer Pyrex for durability. The liquid ratio is crucial for balancing the sauerkraut’s tang with sweetness.

Serving Essentials

A slotted spoon helps serve the sauerkraut while leaving liquid behind. For the pork, a carving knife with a long blade makes clean slices. I use my Wüsthof from culinary school days. 💫
