Ingredients for crock pot pork loin and sauerkraut
Sixteen essential ingredients transform into German-inspired comfort food effortlessly.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin Roast 🥩 | 3 lb | Bone-in, center-cut preferred |
| Sauerkraut 🥬 | 2 cups | Unopened jar, drained |
| Dijon Mustard 🍯 | 2 tbsp | High-quality, smooth variety |
| Ground Caraway Seeds 🌿 | 1 ½ tsp | Freshly ground preferred |
| Fresh Thyme Leaves 🍃 | ¼ cup | Stems removed, chopped |
| Onion 🧅 | 1 whole | Yellow or red, sliced |
| Garlic Cloves 🧄 | 4 cloves | Peeled, minced |
| Beef Broth 💧 | 1 ½ cups | Low-sodium preferred |
| Apple Cider Vinegar 🍎 | 1 tbsp | For tanginess |
| Brown Sugar 🍚 | 1 tbsp | Light or dark |
| Salt 🧂 | 1 ½ tsp | Kosher or sea salt |
| Black Pepper 🌶️ | ½ tsp | Freshly ground |
| Olive Oil 🫒 | 1 tbsp | For searing pork |
| Fresh Parsley 🌿 | ⅛ cup | Chopped, for garnish |
The pork loin roast is the foundation—bone-in, center-cut delivers the best flavor and texture. Look for cuts with good marbling at Whole Foods or your local butcher; the Costco Kirkland Signature brand is consistently reliable. Avoid lean cuts, as they lack the fat needed for tenderizing during slow cooking. The sauerkraut should be vibrant and tangy—avoid any with a brownish hue or off smells. Bubbies or Reinhart brands are top choices, but any unopened jar will work. Freshly ground caraway seeds elevate the dish, but if unavailable, whole seeds toasted and crushed work in a pinch. Thyme and parsley should be bright green, not wilted or yellowed.
No Dijon mustard? Whole-grain mustard thinned with water mimics the texture. Substitute caraway seeds with 1/4 tsp ground allspice for warmth, though the flavor won't be identical. The onion can be swapped for 1 cup chopped celery for a slightly sweeter profile. If you lack apple cider vinegar, white vinegar or lemon juice will add tang, though the flavor will differ. For a sweeter touch, use 1 tbsp honey or maple syrup instead of brown sugar. The beef broth can be replaced with water plus 1 tsp soy sauce, though the depth of flavor will be reduced.
This dish reheats beautifully—2-3 minutes in the microwave or on the stovetop with a splash of broth. Store leftovers in an airtight container for up to 5 days in the fridge or 3 months frozen. For meal prep, portion into individual containers with a side of sauerkraut to maintain texture. The flavors deepen overnight, making it even more delicious the next day. Garnish with fresh parsley just before serving to brighten the dish.

Step-by-step instructions for German-style braised pork loin
Here's the method for tender, flavorful pork with perfectly balanced sauerkraut.
Sear the Pork Loin for Maximum Flavor
Heat a large oven-safe skillet over medium-high heat. Add the 1 tablespoon olive oil and let it get hot enough to shimmer. Place the 3 lb pork loin roast in the skillet, fat-side down, and sear for 5-6 minutes until the exterior develops a deep golden brown crust.
Flip the pork and continue searing for another 4-5 minutes until all sides are well-browned. This step creates the foundational Maillard reaction that builds deep flavor. Press down gently on the pork with a spatula during searing to ensure even contact with the pan. Remove the pork and set it aside on a plate.
Build the Flavor Base in the Same Skillet
In the same skillet (don't wipe out the browned bits), add the sliced whole onion and cook for 5-6 minutes until softened and lightly golden. Add the 4 cloves minced garlic cloves and cook for 30 seconds until fragrant - be careful not to let it burn.
Stir in the 2 tablespoons Dijon mustard, 1.5 teaspoons ground caraway seeds, 1 tablespoon brown sugar, 1.5 teaspoons salt, and 0.5 teaspoon black pepper. Cook for 1 minute until the spices are toasted and the mixture smells aromatic. This creates the flavor foundation for your braise.
Combine All Ingredients in the Crock Pot
Transfer the seared pork to your crock pot. Add the 2 cups sauerkraut, 1.5 cups beef broth, and 1 tablespoon apple cider vinegar to the skillet. Scrape up all the browned bits from the bottom with a wooden spoon, then pour this mixture over the pork in the crock pot.
Sprinkle the 0.25 cup chopped fresh thyme leaves evenly over the top. The sauerkraut should be partially submerged in the liquid, but that's okay - it will soften as it cooks. This combination of ingredients creates the perfect balance of tangy, sweet, and savory flavors.
Cook Until Fork-Tender
Cover the crock pot and cook on low heat for 6-7 hours, or on high heat for 3-4 hours. The pork is done when it reaches an internal temperature of 195-200°F and a fork slides in easily with no resistance.
Real talk: Your oven might run hot, so start checking at the 2-hour mark if using high heat. If the pork seems undercooked, return it to the crock pot for another hour. The longer it cooks, the more tender it becomes. Don't skip this step - patience is key for perfect results.
Rest and Serve with Fresh Garnish
Remove the pork from the crock pot and let it rest for 10-15 minutes before slicing. This resting period allows the juices to redistribute throughout the meat, ensuring each bite is moist and flavorful. Discard any excess liquid that's separated.
Slice the pork into 1-inch thick medallions against the grain. Spoon the sauerkraut and cooking juices over the top, then garnish with the 0.125 cup chopped fresh parsley. Serve immediately with crusty bread or roasted potatoes to soak up all that delicious sauce.
Pro Tips For Making Crock Pot Pork Loin And Sauerkraut
- Sear the Pork First: DESCRIPTION: Brown the pork loin in a hot skillet before dumping it into the crock pot—just 2-3 minutes per side. I used to skip this, and the dish always tasted like it needed more depth. The crust locks in flavor and keeps the meat from drying out later.
- Rinse the Sauerkraut: DESCRIPTION: Drain and rinse the sauerkraut under cold water to cut the sharpness before adding it to the pot. The brine is salty enough to overpower the dish if left unchecked—especially if you’re using a smaller cut of pork.
- Don’t Overfill the Pot: DESCRIPTION: Fill the crock pot only halfway with liquid—about 1 cup of broth or water—and let the pork and sauerkraut release their own juices. Crowding the pot turns the pork into a sad, gray slab instead of tender, juicy slices.
- Toast the Caraway Seeds: DESCRIPTION: Dry-toast the ground caraway seeds in a small pan for 30 seconds until fragrant before mixing them into the mustard. It’s a tiny step, but it makes the flavor pop—like the difference between black pepper and freshly cracked pepper.
Flavor customization for these flavors
Sweet & Tangy Twist
Add ½ cup diced apples (like Honeycrisp or Fuji) along with the onions for a sweet-tart contrast. The apples caramelize beautifully during cooking, balancing the sauerkraut's tang. I also toss in 1 tsp cinnamon with the caraway seeds for warmth.
This variation works especially well with pork shoulder instead of loin for extra richness. 🍎
Smoky BBQ Fusion
Swap the apple cider vinegar for ¼ cup BBQ sauce (I love Sweet Baby Ray's Original) and add 1 tbsp smoked paprika to the spice mix. Cook the pork on high for 4 hours instead of low, then broil for 5 minutes at the end to caramelize the sauce.
Garnish with chopped pickles for extra tang. This fusion keeps the German roots while adding Southern flair. 🔥
Creamy Mustard Sauce
After cooking, blend ½ cup of the cooking liquid with ¼ cup sour cream and 1 tbsp Dijon mustard until smooth. Pour this over sliced pork before serving. The cool creaminess cuts through the richness, creating a restaurant-worthy sauce.
For extra decadence, add 1 oz melted butter to the blend. This works especially well with bone-in pork chops instead of loin. 🥄
Herb-Infused Sauerkraut
Before adding the sauerkraut to the crock pot, sauté 1 tbsp fresh dill and 1 tsp fennel seeds in the skillet with the onions. The dill adds brightness while fennel complements the caraway.
For a more robust flavor, add 1 sliced bay leaf to the crock pot during cooking. This herb combo transforms the sauerkraut into a flavorful side that stands on its own. 🌿
Spicy Kick Option
Add 1 tsp cayenne pepper or 2 sliced jalapeños to the crock pot for heat lovers. The jalapeños soften during cooking but retain their subtle spice. For smoky heat, add ½ tsp chipotle powder with the other spices.
Balance the heat with extra brown sugar if needed. This variation pairs perfectly with cornbread for a Southern-German mashup. 🌶️
Wine Braising Liquid
Replace the beef broth with 1 cup dry Riesling or Chardonnay plus ½ cup beef broth**. The wine adds acidity that brightens the dish while preventing the sauerkraut from becoming too mushy.
Deglaze the skillet with the wine after searing the pork for maximum flavor extraction. This upgrade makes the dish feel more sophisticated without extra effort. 🍷

Frequently asked questions
Can I use bone-in pork chops instead of a pork loin roast?
Yes! Use 6 bone-in pork chops (about 8 oz each) and reduce the cooking time to 3-4 hours on high or 5-6 hours on low. Sear them individually first, then place them in the crock pot with the sauerkraut mixture. The bones add extra flavor to the braising liquid, making it even richer.
Why does my sauerkraut turn mushy in the crock pot?
Sauerkraut softens naturally during slow cooking, but too much liquid or overcooking causes mushiness. Use 2 cups sauerkraut as directed and avoid adding extra broth. If needed, drain excess liquid after 4 hours of cooking and return the pork to the pot. For firmer texture, add sauerkraut only in the last 2 hours of cooking.
What's the best way to reheat leftovers?
Reheat in the crock pot on low for 1-2 hours with a splash of water or broth to prevent drying. For quick reheating, use the microwave for 2-3 minutes covered with a damp paper towel. The sauerkraut reheats best when warmed gently—never microwave dry. Leftovers taste even better the next day!
Can I make this recipe without caraway seeds?
Substitute with ½ tsp ground allspice for warmth or 1 tsp celery seeds for a similar earthy note. If you prefer no substitutes, skip them—the dish will still be delicious, just with a more subtle flavor profile. The mustard and thyme will still provide depth.
How do I know when the pork is fully cooked?
The pork is done when it reaches an internal temperature of 195-200°F and a fork slides in easily with no resistance. For bone-in cuts, check the thickest part of the meat near the bone. If using a meat thermometer, insert it horizontally into the thickest part of the pork loin to get an accurate reading.
