Pork Tenderloin and Sauerkraut Instant Pot Recipe: Tangy German-Style One-Pot Meal

This one-pot recipe brings German flavors to your table with minimal effort. The Instant Pot transforms pork tenderloin into tender, juicy perfection while sauerkraut develops a rich, tangy depth.

I developed this method to capture traditional taste without the long cook time. The pressure cooker infuses the pork with sauerkraut’s briny character, creating a harmonious balance between savory meat and zesty fermented cabbage.

You’ll love how the pork emerges fall-apart tender and the sauerkraut softens just enough to soak up all the flavors. It’s a complete meal that feels special but comes together with everyday ingredients.

Serve with mashed potatoes or crusty bread to soak up every drop. This dish delivers restaurant-quality results with a fraction of the work.

Ingredients for Pork Tenderloin and Sauerkraut Instant Pot

Pantry staples and a pork tenderloin make this German-style one-pot meal a breeze.

The pork tenderloin is the star—look for 1.5 lb pieces at Costco or your local butcher (they’re usually sold in pairs, so freeze one for later). Sauerkraut quality matters: Libby’s or Frank’s in the refrigerated section have better texture than shelf-stable. The apple adds a touch of sweetness that balances the tang (Granny Smith holds up best).

No sauerkraut? Shredded green cabbage with 2 tbsp vinegar works in a pinch, but the flavor won’t be as deep. Out of caraway seeds? Skip the juniper berries and add extra mustard for that German kick. The broth can be vegetable broth if you’re avoiding meat—just add a pinch of smoked salt for depth. Baby carrots? Not here, but sliced regular carrots work if you’ve got them.

Leftovers taste even better the next day once flavors meld. Stores 4 days in the fridge or freezes for 3 months. Reheat gently on the stove with a splash of broth (don’t microwave—the sauerkraut gets mushy).

Step-by-Step Instructions for Pork Tenderloin and Sauerkraut

This one-pot method delivers tender pork with tangy, caramelized sauerkraut—all in your Instant Pot.

Step 1: Sear and Season the Pork Tenderloin

Pat the 1.5 lb Pork Tenderloin dry and season generously with the 1 tsp Kosher Salt and 0.5 tsp Black Pepper. Set your Instant Pot to the sauté function and add the 1 tbsp Olive Oil.

When the oil shimmers, sear the pork on all sides for 2-3 minutes per side until deep golden brown. This builds a flavorful crust and locks in juices. Don’t rush—you want a good sear before the pork releases easily from the pot.

Step 2: Build the Flavor Base

Remove the pork and set aside. Add the 1 whole Yellow Onion (thinly sliced), 1 whole Granny Smith Apple (cored and diced), and 3 cloves Garlic Cloves (minced) to the pot. Sauté for 3-4 minutes until the onion softens and the apple begins to break down.

Stir in the 1 tsp Caraway Seeds, lightly crushed, along with the 6 whole Juniper Berries (also crushed) and 1 whole Bay Leaf. This aromatic trio infuses the dish with classic German flavors. Cook for 1 minute until fragrant.

Step 3: Deglaze and Layer Ingredients

Pour in the 1 tbsp Apple Cider Vinegar and scrape the bottom of the pot to release all the browned bits—this step prevents burning and adds depth to the sauce. Add the 2 tbsp Dijon Mustard, 1 tbsp Brown Sugar, and 0.75 cup Chicken Broth, stirring to combine.

Return the pork to the pot and arrange it on top of the mixture. Spread the 1 lb Sauerkraut (drained and rinsed) evenly around the pork, pressing it down slightly to submerge in the liquid. The sauerkraut should be mostly covered to soften properly.

Step 4: Pressure Cook to Perfection

Secure the lid, set the valve to sealing, and cook on high pressure for 15 minutes. The pork should reach an internal temperature of 145°F and be tender but not falling apart. Once the cooking cycle ends, let the pressure release naturally for 10 minutes, then quick-release any remaining pressure.

This natural release ensures the pork stays juicy and the sauerkraut absorbs all the tangy, savory flavors. The apple and onion will have melted into the sauce, creating a rich, slightly sweet base.

Step 5: Rest and Serve

Remove the pork and let it rest on a cutting board for 5 minutes. Slice it into ½-inch thick medallions and return them to the pot. Stir everything together so the pork soaks up the flavorful juices.

Discard the bay leaf before serving. The sauerkraut should be tender with a slight bite, and the sauce should cling lightly to the pork. Serve hot, and enjoy the balance of tangy, sweet, and savory in every bite.

Serving Suggestions for Leftovers

Plating Presentation

I like to arrange the pork medallions in a circular pattern on a large platter, with the sauerkraut mounded in the center. This creates visual appeal while keeping the flavors cohesive. A sprinkle of fresh parsley adds a pop of color. 💫

Bread Pairings

Serve with thick slices of rustic sourdough or pumpernickel bread to soak up the tangy juices. Warm the bread and brush with garlic butter for extra richness. Rye bread also complements the German flavors beautifully.

Potato Sides

Buttery mashed potatoes or crispy roasted fingerlings balance the dish’s acidity. For mashed, I fold in a splash of buttermilk for tang. Roast potatoes with rosemary and olive oil for a hearty contrast.

Vegetable Additions

Steamed green beans or sautéed red cabbage add color and texture. Toss either with a little apple cider vinegar to echo the sauerkraut’s tang. Braised Brussels sprouts with bacon also pair wonderfully.

Garnish Ideas

A dollop of whole-grain mustard on the side lets guests add extra zing. Pickled red onions or cornichons on the plate cut through the richness. Fresh dill adds a bright, herby note.

Serving Temperature

This dish is best served hot, straight from the Instant Pot. If making ahead, reheat gently on the stove with a splash of broth. The flavors deepen over time, making leftovers even more delicious. ❄️
