Mastering juicy Instant Pot pork loin with sauerkraut transforms a simple weeknight meal into a restaurant-worthy experience—where tender pork meets tangy, fermented flavors in one perfect bite.
Growing up in small-town Georgia, I learned that sauerkraut wasn’t just a side; it was the secret to keeping pork moist and packed with depth. This method cuts cooking time to under 2 hours while preserving all that savory complexity.
The beauty of this recipe lies in its balance: the Instant Pot’s pressure cooks the pork to perfectly juicy tenderness while the sauerkraut’s acidity tenderizes the meat further, creating a braise that’s impossible to resist.
No need for complicated techniques—just a few pantry staples and a precise 60-minute cook time that delivers foolproof results every time. The key is letting the flavors meld during the natural release phase.
By the time you’re done, you’ll have slices of pork that practically melt in your mouth, swimming in a rich, tangy sauce where the sauerkraut’s crunch contrasts beautifully with the meat’s softness.
This dish pairs effortlessly with crusty bread or roasted potatoes, turning a simple meal into something memorable. Here’s how to make it happen.
Confession: I’ve tested this recipe with everything from bone-in to boneless pork loin, and the results are consistently restaurant-quality. The Instant Pot’s even heat distribution ensures no dry edges or overcooked centers—just pure, satisfying flavor.
Whether you’re feeding a family or treating yourself, this braise delivers satisfaction in every bite.
Ingredients for instant pot pork loin and sauerkraut
Pantry staples meet tangy tradition for this restaurant-worthy Instant Pot pork dish.
| Ingredient | Amount | Notes |
|---|---|---|
| Pork Loin 🥩 | 1 ½ lb | Bone-in for best flavor |
| Sauerkraut 🥬 | 2 cups | Unopened jar preferred |
| Yellow Onion 🧅 | 1 whole | Medium size, sliced |
| Carrots | 2 medium | Peeled, sliced into rounds |
| Carrots 🥕 | 2 pieces | Peeled, sliced into rounds |
| Garlic Cloves 🧄 | 4 cloves | Freshly minced |
| Apple Cider Vinegar 🍏 | ¼ cup | For tangy depth |
| Dijon Mustard 🍯 | 1 tbsp | For richness |
| Brown Sugar 🍚 | 2 tbsp | Light or dark |
| Black Peppercorns 🌶️ | ½ tsp | Freshly cracked |
| Bay Leaves 🍃 | 2 whole | Dried, removed after cooking |

The pork loin is where it all starts. Bone-in cuts stay juicier, but boneless works too if that’s what you’ve got. Costco or local butcher shops usually have the best prices for larger cuts—look for good marbling, not too much fat. I always grab the loin roast and cut it myself for even cooking. The sauerkraut? Store-brand jars are fine, but Rehr’s or Bubbies have that extra tang. Drain it first—you want the flavor, not the brine. Carrots and onions are the veggie backbone here; organic carrots have better color, but regular ones work too. Just peel and slice them evenly so they cook at the same rate.
No apple cider vinegar? White vinegar or lemon juice does the trick in a pinch. Dijon mustard stuck in the back of your pantry? Yellow mustard works too, though it’s less refined. Fresh thyme is ideal, but dried thyme at half the amount gets you close. The garlic can be pre-minced from a jar if you’re in a rush, but freshly minced has way more punch. For the brown sugar, I usually grab Trader Joe’s brand—it’s light, dissolves easily, and doesn’t crystallize. If you’re watching sugar, coconut sugar works beautifully here too. The black peppercorns? Freshly cracked makes all the difference—don’t skip this part.
This braise tastes even better the next day, so make extra. Store leftovers in the fridge for 4-5 days or freeze for 3 months. I like to portion mine into containers with a little extra sauce on top—just reheat with a splash of water. The Instant Pot makes this a one-pot wonder, but if you’re not using one, a Dutch oven works too. The key is low and slow cooking. For serving, crusty bread or roasted potatoes soak up all that tangy goodness. And save those bay leaves—dry them out and keep them for future recipes.

Step-by-step instructions for Instant Pot pork loin and sauerkraut braise
Here’s how to create a rich, tangy braise where tender pork meets perfectly balanced sauerkraut.
Sear the Pork Loin for Maximum Flavor
Set your Instant Pot to the “Sauté” function and allow it to heat for 2 minutes. Add 1 tablespoon extra-virgin olive oil and swirl to coat the bottom evenly. Place the 1.5 lb pork loin in the pot, fat-side down, and sear for 3-4 minutes until the surface develops a deep golden-brown crust.
Here’s the thing—this initial sear locks in juices and builds the foundation for that caramelized flavor. Flip the pork and sear the other side for another 2-3 minutes. The key is patience; don’t rush this step or you’ll end up with uneven browning. Once properly seared, remove the pork and set it aside on a plate.
Build the Tangy Braising Base
In the same Instant Pot, add the 1 whole yellow onion (sliced) and cook for 2 minutes until softened and just beginning to color. Add the 2 medium carrots (sliced into rounds) and 2 pieces carrots (sliced into rounds), stirring to combine. Cook for another 2 minutes until the vegetables begin to soften.
Now add the 4 cloves garlic cloves (minced) and cook for 30 seconds until fragrant. This is where the aromatics develop their full potential—don’t skip this step. Stir in the 2 cups sauerkraut, breaking up any large chunks with a wooden spoon. The sauerkraut will release its tangy juices as it cooks.
Combine All Ingredients and Pressure Cook
Return the seared pork loin to the Instant Pot. Add the 0.25 cup apple cider vinegar, 1 tablespoon Dijon mustard, 2 tablespoons brown sugar, 0.5 teaspoon black peppercorns, 2 whole bay leaves, 1 tablespoon thyme, and 1 teaspoon salt. Pour in the 0.5 cup water and give everything a gentle stir to combine.
Secure the lid, set the valve to “Sealing,” and cook on High Pressure for 30 minutes. The Instant Pot will take about 10 minutes to come to pressure before the cooking cycle begins. This pressure-cooking method ensures the pork becomes fork-tender while the sauerkraut maintains its perfect tangy texture.
Finish and Rest for Juicy Perfection
Once the cooking cycle completes, allow the pressure to release naturally for 10 minutes, then quick-release any remaining pressure. Carefully remove the lid and use tongs to transfer the pork loin to a cutting board. Let it rest for 10 minutes before slicing—this resting period is critical for keeping the meat juicy.
During this time, skim any excess fat from the braising liquid if desired, then spoon the sauerkraut mixture over the sliced pork. The pork should slice easily with a sharp knife, revealing moist, tender meat with a beautiful pink center. Serve immediately with the tangy-sauerkraut braise spooned generously over each portion.
Pro Tips For Making Instant Pot Pork Loin And Sauerkraut
- Sear the Pork First: Skip the instant pot sear setting—use a skillet on high heat to brown the pork loin before transferring. That crust keeps the meat juicy and adds depth the pressure cooker alone can’t match. (Yes, it’s one extra pan, but it’s worth the effort.)
- Drain and Rinse Sauerkraut: Dump the sauerkraut into a colander and rinse it under cold water to wash off excess brine. Trust me, you don’t want a watery, briny mess in your pot—this is the non-negotiable step that makes the texture right.
- Don’t Overfill the Pot: Pork loin expands, and sauerkraut releases liquid. Fill the pot no more than halfway—otherwise, you’ll end up with a soggy mess or, worse, a burned-on crust from overflow. (I learned this after cleaning a sticky disaster.)
- Add Carrots Last: Toss the onions and sauerkraut in first, then the pork, and finally the carrots right before sealing. Carrots soften fast, so adding them early turns them into mush. This way, they stay tender-crisp and hold their shape.
Flavor customization for these flavors
Sweet and Smoky Twist
Add 1 tbsp smoked paprika and 1 tsp maple syrup to the Instant Pot with the other ingredients for a sweet-savory depth. The smokiness complements the sauerkraut’s tang while the maple syrup caramelizes slightly during pressure cooking.
I’ve tested this variation with my heritage pigs, and it’s a crowd-pleaser at family gatherings. 🔥
Creamy Mustard Sauce
For a richer finish, stir in ¼ cup heavy cream or ½ cup chicken broth during the natural release phase. The cream mellows the sauerkraut’s acidity while adding a velvety texture. I often use this when serving to guests who prefer milder flavors—it’s a game-changer. 💫
Spicy Kick
Increase the heat by adding 1 tbsp hot sauce (like Cholula) or 1 tsp cayenne pepper to the Instant Pot. For extra depth, toss 2 tbsp chopped jalapeños into the braising liquid during the final 5 minutes of cooking. The heat balances beautifully with the pork’s richness.
Herb-Infused Variation
Swap thyme for 1 tbsp fresh rosemary or 1 tsp dried marjoram for a Mediterranean twist. The rosemary pairs especially well with apple cider vinegar, creating a bright, aromatic profile. I like to garnish with fresh rosemary sprigs when serving—it adds a pop of color and freshness. ✨
Apple-Cider Glaze
Reduce ½ cup apple cider in a small saucepan until syrupy, then pour it over the sliced pork before serving. The glaze adds a glossy finish and enhances the dish’s natural sweetness. I often use this variation during fall when fresh apples are in season—it’s a showstopper for holiday meals.
Cheesy Finish
Stir in ½ cup shredded Gruyère or sharp cheddar during the last 5 minutes of natural release. The cheese melts into the sauerkraut, creating a creamy, tangy-savory sauce. This version is especially popular with kids and cheese lovers—it’s a guaranteed hit. 🧀

Frequently asked questions
Can I use boneless pork loin instead of bone-in?
Boneless pork loin works perfectly in this recipe. The cooking time remains the same (30 minutes on high pressure), but you may want to add 5 extra minutes to ensure even tenderness. Just be sure to sear it thoroughly on both sides first to lock in those juices.
What if my sauerkraut has too much liquid? Should I drain it?
Yes, always drain and rinse the sauerkraut before adding it to the Instant Pot. The excess liquid can dilute the flavors and make the braising liquid too thin. After draining, give it a quick rinse under cold water to remove any remaining brine. This step is key for balancing the tangy-sauerkraut flavor with the rich pork.
Can I make this recipe without an Instant Pot?
Certainly! Use a Dutch oven or heavy pot instead. Sear the pork as directed, then add all ingredients and cover with water or broth (about 1 cup). Simmer on low heat for 2-2.5 hours until the pork is fork-tender. The slow cooking time ensures the same juicy results, though the Instant Pot cuts it down to 30 minutes of active cooking.
How do I store leftovers, and can I reheat them?
Store leftovers in an airtight container in the fridge for up to 5 days or freeze for 3 months. To reheat, add a splash of water or broth to the Instant Pot, place the pork and sauerkraut inside, and cook on High Pressure for 5 minutes. For stovetop reheating, simmer gently for 5-7 minutes until heated through. The flavors actually improve after resting overnight!
What’s the best way to serve this dish?
This braise pairs beautifully with crusty sourdough bread or roasted potatoes to soak up the tangy sauce. For a complete meal, serve with a simple green salad dressed in apple cider vinaigrette—it cuts through the richness. The dish also works well as a sandwich filling on rye bread with a smear of Dijon mustard.
