Ingredients for instant pot spare ribs and sauerkraut

Restaurant-quality spare ribs and sauerkraut in under an hour—just these 15 ingredients transform tough cuts into tender perfection.

The pork spare ribs are the foundation, so prioritize quality cuts with good marbling. Costco or Whole Foods carry excellent bone-in options, and always opt for fresh rather than pre-marinated. For the sauerkraut, Bubbies or Rehr's brands deliver consistent fermentation and vibrant flavor. The smoked paprika should be labeled 'smoked'—not cayenne or sweet—since it carries the authentic barbecue depth. Fresh herbs like thyme and rosemary elevate the dish, so Trader Joe's or local farmers' markets are ideal sources for these. The apple cider vinegar should be raw and unfiltered for maximum tang, while the molasses should be unsulphured to avoid metallic aftertaste.

No smoked paprika? Substitute 1 tsp liquid smoke plus 1 tsp sweet paprika for a similar effect. Running low on fresh thyme? Dried thyme works at one-third the amount, but fresh is preferred for its bright aroma. The beef broth can be swapped for chicken broth if unavailable, though beef adds richer depth. For the sauerkraut, if you prefer a milder tang, drain and rinse it briefly before adding. The honey can be omitted if you're watching sugar, but it balances the acidity beautifully. If your garlic is particularly pungent, reduce to 4 cloves to avoid overpowering the dish. The brown sugar should be packed into the measuring cup—light or dark both work, but dark adds subtle molasses notes.

Store prepped ribs in the fridge for up to 2 days before cooking, though they're best used immediately. The sauerkraut can be prepped ahead and refrigerated for 3 days in its juices, but it's best added fresh for optimal texture. Once cooked, the ribs and sauerkraut keep for 4 days in the refrigerator, though flavor peaks within the first two days. For longer storage, freeze the ribs and sauerkraut separately for up to 3 months. Reheat gently in the Instant Pot on 'sauté' mode with a splash of broth to maintain moisture. The dish reheats beautifully and tastes even better the next day as flavors meld.

Step-by-step instructions for Instant Pot spare ribs with sauerkraut

This method delivers fall-off-the-bone ribs with a tangy-sweet glaze and crisp sauerkraut in under 2 hours.

Set your Instant Pot to "Sauté" mode and add the 1 tablespoon extra-virgin olive oil. Once shimmering, carefully arrange the 3 lb pork spare ribs in a single layer, bone-side down. Let them sear undisturbed for 4-5 minutes until deep golden brown forms on the meat. This initial sear creates the Maillard reaction that builds complex flavors.

Flip each rib and continue searing for another 3-4 minutes. The ribs should develop a rich caramelized crust while maintaining their shape. I press down gently on the ribs during the first minute to prevent curling, which ensures even contact with the pan. If the oil begins to smoke excessively, reduce heat slightly to maintain control without losing the sear.

Remove the ribs from the pot and set aside. In the same pot, add the sliced 1 whole yellow onion and smashed 6 garlic cloves. Sauté for 2-3 minutes until the onions soften and become translucent, releasing their sweet aroma. This step forms the aromatic base for your braising liquid.

Stir in the 2 teaspoons smoked paprika and 1 teaspoon ground black pepper, letting them toast for 30 seconds until fragrant. Immediately add the 0.5 cup packed brown sugar, 0.25 cup apple cider vinegar, 0.25 cup unsulphured molasses, 1.5 cups low-sodium beef broth, 0.25 cup chopped fresh thyme leaves, and 2 sprigs rosemary (woody stems removed). Scrape up any browned bits from the bottom of the pot with a wooden spoon—these contain concentrated flavor.

Return the seared ribs to the pot, bone-side up, and arrange them in a single layer. Sprinkle the ribs evenly with the 1.5 teaspoons diamond crystal kosher salt. Secure the lid, set the valve to "Sealing," and cook on "High Pressure" for 60 minutes. This pressure cooking time ensures the connective tissue breaks down while maintaining moisture.

During this time, the ribs will absorb the complex braising liquid infused with tangy vinegar, sweet molasses, and smoky paprika. The natural acids in the apple cider vinegar and fermented sauerkraut will tenderize the meat further, creating that signature pull-apart texture. Do not open the lid during cooking—releasing pressure prematurely can compromise texture.

Once the cooking cycle completes, allow the pressure to release naturally for 10 minutes before quick-releasing any remaining pressure. Carefully remove the lid and stir in the 1.5 cups packed sauerkraut. The tangy fermentation will contrast beautifully with the sweet glaze on the ribs, creating a perfect balance of flavors.

Return the lid to the pot and let it sit on "Keep Warm" for 10 minutes. This resting period allows the ribs to absorb any remaining braising liquid while the sauerkraut softens slightly. The natural acids in the sauerkraut will help break down any remaining connective tissue, ensuring maximum tenderness.

Remove the ribs to a serving platter. Discard the rosemary sprigs and strain the braising liquid through a fine-mesh sieve into a saucepan. Return the liquid to medium heat and simmer until reduced by half, about 5-7 minutes. Stir in the 2 tablespoons raw honey and let it dissolve completely, creating a glossy glaze.

Brush the reduced glaze generously over the ribs and serve immediately with the sauerkraut spooned alongside. The ribs should be fork-tender with a glossy, caramelized surface, while the sauerkraut maintains its crisp texture. Each bite delivers a perfect harmony of smoky, sweet, and tangy flavors that complement each other beautifully.

Essential equipment for perfect results

Instant Pot Essentials

The Instant Pot Duo Crisp is my top recommendation for this recipe—its crisp function creates that perfect caramelized crust on the ribs that you'd normally get from slow smoking.

If you don't have a Duo Crisp, any 6-quart Instant Pot with a pressure cooking function will work, though you'll need to broil the ribs separately for that crispy finish. I've tested this recipe in Instant Pot Lux 6-in-1 models and found the results equally excellent. 🔥

Precision Tools

A meat thermometer is non-negotiable for perfect ribs—they should reach 203°F internal temperature at the bone. I use the ThermoWorks Smoke because it's durable and accurate, but any probe thermometer with a 144°F to 220°F range will do.

For measuring liquids, a liquid measuring cup ensures you get the exact 1.5 cups of sauerkraut and 1.5 cups of beef broth called for in the recipe. Never eyeball these measurements—precision matters with pressure cooking.

Searing Equipment

Your Instant Pot's sauté function replaces the need for a separate skillet, but if you prefer, a 12-inch cast iron skillet like the Lodge Pre-Seasoned gives you better heat control for searing.

I use my Instant Pot's sauté setting for convenience, but if your pot's function is weak, transfer the ribs to a non-stick skillet for that perfect sear. A wooden spoon is essential for scraping up those flavorful browned bits from the bottom of the pot—those bits are pure flavor gold.

Sauerkraut Handling

For the sauerkraut, I recommend using a fine-mesh strainer if you want to drain excess liquid before adding it to the ribs. This prevents your braising liquid from becoming too watery during cooking. A quart-sized mason jar works perfectly for packing and storing sauerkraut in the fridge.

If you're serving this dish at a gathering, a large serving spoon helps portion the sauerkraut neatly alongside the ribs. 🥬

Glazing Supplies

The finishing glaze requires a small saucepan for reduction—I use my 3-quart stainless steel saucepan from All-Clad. A silicon brush makes it easy to apply that glossy honey glaze evenly over the ribs without making a mess.

For serving, I like to use wooden serving boards because they add rustic charm and keep the ribs warm while you're plating. If you're feeling fancy, a small offset spatula helps lift the ribs without breaking them apart.

Optional Upgrades

For an extra-smoky flavor, I sometimes add 1 teaspoon of liquid smoke to the braising liquid during the sauté phase. A high-quality microplane helps zest fresh ginger if you want to add 1 teaspoon for extra depth.

If you're serving this dish outdoors, a portable propane burner lets you reduce the glaze anywhere. For meal prep, glass storage containers with snap-on lids keep the ribs and sauerkraut fresh for up to 4 days in the fridge. 💡
