Instant Pot Recipe for Pork Ribs and Sauerkraut: Tangy Braised Tenderness in 60 Minutes

My grandmother’s handwritten recipe cards were maddeningly vague, but her pork ribs and sauerkraut taught me the power of patience. This Instant Pot version delivers the same tender results in a fraction of the time.

What takes all day in a slow cooker comes together in 60 minutes under pressure. The ribs emerge fall-off-the-bone tender, while the sauerkraut absorbs rich pork flavors without losing its tang.

The secret is layering the ingredients properly and using the pressure cooker’s natural release to maintain moisture. No heroic effort required—just straightforward cooking with guaranteed results.

You’ll end up with a hearty, flavorful dish that tastes like it simmered for hours. Perfect for weeknight comfort without the wait.

Ingredients for Instant Pot Recipe for Pork Ribs and Sauerkraut

Pork ribs and sauerkraut come together with bold spices for a hearty Instant Pot meal.

The pork ribs are non-negotiable here. Baby back ribs offer the best tender-to-bone ratio for pressure cooking. Source from a reputable butcher or Whole Foods for consistent quality. Look for ribs with even marbling—this fat renders down during cooking, infusing the sauerkraut with rich flavor. Avoid pre-cut ribs; buy a full rack and portion yourself for uniform cooking.

No caraway seeds? Fennel seeds at half the amount provide a similar anise note. Apple juice or dry white wine can replace the vinegar if needed. For the sauerkraut, refrigerated bagged versions (found near deli meats) outperform canned—they retain better texture. If using canned, rinsing thoroughly removes excess sodium without stripping all the tang.

Store uncooked ribs in the fridge for up to 3 days or freeze for 6 months. Sauerkraut keeps for 1 week once opened. Leftovers taste even better the next day—reheat gently to preserve the ribs’ fall-off-the-bone texture.

Step-by-Step Instructions for Pork Ribs and Sauerkraut

This method guarantees fall-off-the-bone ribs and perfectly balanced sauerkraut in under an hour.

Step 1: Prepare the Ribs and Aromatics

Cut the 2.5 lb pork baby back ribs into individual ribs using a sharp knife. This exposes more surface area for even cooking and flavor absorption. Season the ribs with 1 tsp kosher salt and set aside.

Thinly slice the yellow onion and mince the 4 cloves garlic cloves. Lightly crush the 1 tsp caraway seeds, 4 pieces juniper berries, and 1 tsp black peppercorns using a mortar and pestle or the flat side of your knife. This releases their essential oils for maximum flavor impact.

Step 2: Build the Flavor Base

Select the Sauté function on your Instant Pot. Add the sliced onion and cook for 3-4 minutes until it begins to soften and turn translucent. Add the minced garlic and cook for an additional 30 seconds until fragrant.

Stir in the 2 tbsp granulated sugar, allowing it to caramelize slightly with the onions. This creates a sweet foundation that balances the tanginess of the sauerkraut. Add the 1 tbsp Dijon mustard and cook for 1 minute, stirring constantly to prevent burning.

Step 3: Combine All Ingredients

Add the 1 lb sauerkraut (drained and rinsed lightly) to the pot, spreading it evenly across the bottom. Place the seasoned ribs on top of the sauerkraut in a single layer if possible.

Pour the 0.25 cup apple cider vinegar and 0.5 cup chicken broth over everything. Add the crushed spices, 1 whole bay leaf, and stir gently to distribute the liquid without dislodging the ribs. The liquid should nearly cover the sauerkraut but not submerge the ribs completely.

Step 4: Pressure Cook to Perfection

Secure the lid and set the valve to Sealing. Cook on High Pressure for 25 minutes. The ribs will become tender as the collagen breaks down under pressure, while the sauerkraut absorbs the rich pork flavor.

Allow the pressure to release naturally for 10 minutes, then quick-release any remaining pressure. This natural release period prevents the ribs from toughening due to sudden pressure changes. The ribs should be fork-tender and the sauerkraut should have softened considerably.

Step 5: Reduce and Serve

Remove the lid and discard the bay leaf. If the liquid appears too thin, select the Sauté function again and simmer for 3-5 minutes until it reaches your desired consistency.

Taste and adjust seasoning with additional salt if needed. The sauerkraut should have a balanced sweet-tangy flavor, with the ribs easily pulling away from the bone. Serve hot, with the ribs nestled in the sauerkraut and a portion of the cooking liquid spooned over the top for maximum flavor.

Essential Equipment for This Recipe

Instant Pot Essentials

Your 6-quart Instant Pot is non-negotiable here—it’s the perfect size for 2.5 lb ribs and all the sauerkraut. I’ve tried smaller models, and they just don’t give the ribs enough space to cook evenly. 💪

Sharp Knife

A good 8-inch chef’s knife makes quick work of cutting the ribs into individual pieces. I swear by my Victorinox Fibrox—it’s affordable and stays sharp. Dull knives slip, and that’s how accidents happen.

Mortar and Pestle

Crushing the caraway seeds, juniper berries, and black peppercorns releases their oils for maximum flavor. A granite mortar and pestle works best, but the flat side of your knife in a pinch does the job too.

Wooden Spoon

A wooden spoon is ideal for stirring the onions and sauerkraut without scratching your Instant Pot’s non-stick lining. I keep mine right in the utensil crock next to the stove for easy access.

Measuring Tools

Precise measurements matter here—use measuring spoons for the caraway seeds and Dijon mustard, and a liquid measuring cup for the apple cider vinegar and broth. Eyeballing it works sometimes, but not with this recipe.

Tongs

For serving, a pair of locking tongs lets you lift the ribs out without breaking them. I love the OXO Good Grips—they’re sturdy and easy to clean. Plus, they’re just the right length for reaching into the Instant Pot. 🔥
