Instant Pot Korean Ribs Recipe: Sweet and Spicy Fall-Off-The-Bone Tender

I’ve perfected the art of making fall-off-the-bone tender Korean ribs in the Instant Pot, delivering restaurant-quality results in a fraction of the time. The pressure cooker locks in moisture while infusing the meat with bold, sweet-spicy flavors.

This method combines a rich marinade of soy sauce, brown sugar, garlic, and gochujang with the Instant Pot’s precision to break down the ribs into melt-in-your-mouth perfection. No long braising required.

The result is tender ribs with a glossy, caramelized glaze that clings to every bite. The meat pulls away from the bone effortlessly, making it ideal for family dinners or special occasions.

Serve with steamed rice and quick-pickled vegetables for a complete meal. Here’s how to make it.

Ingredients for Instant Pot Korean Ribs

Pantry staples meet bold Korean flavors for these Instant Pot ribs.

The ribs are everything here. Baby back ribs give you that perfect meat-to-bone ratio—avoid the chewier spare ribs. Costco has great pre-cut racks, but any butcher can split them for you. Look for ribs with good marbling (those white fat streaks mean flavor). The gochujang is non-negotiable—H Mart or a well-stocked Asian aisle will have it. Don’t settle for sriracha; it’s not the same.

No gochujang? Miso paste plus a dash of sriracha gets you 70% there (not perfect, but works). Brown sugar can be swapped for coconut sugar or maple syrup. Fresh ginger is best, but ground ginger at half the amount in a pinch. The soy sauce should be low-sodium so you can control the salt—Kikkoman is my go-to. Short on time? Use pre-minced garlic from a jar (just don’t tell the purists).

Marinate the ribs overnight for maximum flavor—24 hours is ideal. Leftovers keep 4-5 days in the fridge and reheat like a dream. The sauce thickens as it cools, so thin with water if needed. Always garnish fresh for that restaurant-quality finish.

Step-by-Step Instructions for Korean Ribs

Here’s the method that guarantees fall-apart tenderness with bold Korean flavors every time.

Step 1: Sear the Ribs for Maximum Flavor

Heat the 1 tbsp vegetable oil in the Instant Pot using the sauté function on normal heat. While it heats, pat the 2.5 lb baby back ribs dry—this ensures a good sear instead of steaming. I cut them into individual ribs first for even cooking and better sauce coverage.

Sear the ribs in batches for 3-4 minutes per side until deeply browned. Don’t overcrowd the pot. You’re looking for that rich, caramelized crust that develops when the natural sugars in the meat hit the hot surface. This step builds the foundation of flavor for the entire dish.

Step 2: Build the Korean-Inspired Sauce

After removing the ribs, add the 6 cloves minced garlic cloves and 1 tbsp grated fresh ginger to the pot. Sauté for 30 seconds until fragrant—just until the raw edge comes off the garlic. It burns easily, so keep it moving.

Pour in the 0.75 cup soy sauce, 0.5 cup packed brown sugar, 3 tbsp gochujang, 2 tbsp rice vinegar, and 1 tbsp sesame oil. Stir well to dissolve the brown sugar completely and deglaze the pot, scraping up all those flavorful browned bits from searing the ribs.

Step 3: Pressure Cook to Fall-Off-The-Bone Tenderness

Return all the ribs to the Instant Pot and pour in the 0.5 cup water. Secure the lid and set the valve to sealing. Cook on high pressure for 25 minutes—this is the magic number for ribs that are tender but not mushy.

Let the pressure release naturally for 10 minutes, then quick-release any remaining pressure. This gradual release helps the ribs retain their moisture and prevents them from drying out. When you open the lid, you’ll see the meat has pulled back from the bones slightly—a perfect sign of tenderness.

Step 4: Thicken the Sauce and Finish

Remove the ribs and set them aside. Skim any excess fat from the sauce, then bring it to a simmer using the sauté function. Mix the 1 tbsp cornstarch with 2 tbsp of cold water to create a slurry, then stir it into the simmering sauce.

Cook for 2-3 minutes until the sauce thickens enough to coat the back of a spoon. Return the ribs to the pot and toss them in the glossy, thickened sauce. The sauce should cling beautifully to each rib, with a balance of sweet, spicy, and umami flavors.

Garnish with 4 whole thinly sliced green onions and 1 tbsp toasted sesame seeds just before serving. The contrast of the fresh green onions and nutty sesame seeds adds the perfect finishing touch to this dish.

Troubleshooting This Recipe

Sauce Too Thin

If your sauce isn’t thickening after adding the cornstarch slurry, you likely need more time. Let it simmer for an additional 3-5 minutes on sauté mode. If still thin, mix another ½ tbsp cornstarch with 1 tbsp cold water and stir in gradually. 💡

Ribs Not Tender

Undercooked ribs usually mean insufficient pressure time. Ensure you cooked on high pressure for 25 minutes with a full 10-minute natural release. If they’re still tough, return them to the pot with extra ½ cup water and cook for another 10 minutes.

Burn Notice

This often happens if the sauce is too thick before pressure cooking. Always deglaze the pot thoroughly after searing, scraping up all browned bits with the soy sauce mixture. If you get the burn notice, release pressure, add ¼ cup water, and restart.

Sauce Too Salty

Balance is key with soy sauce. Use low-sodium soy sauce as specified. If it’s still too salty, stir in 1 tbsp brown sugar or 1 tbsp rice vinegar to mellow the flavor. You can also dilute with ¼ cup water if needed.

Sauce Too Spicy

Gochujang packs heat. If it overpowers, add 2 tbsp honey or 2 tbsp brown sugar to sweeten. For immediate relief, stir in ¼ cup coconut milk to cool the spice while adding richness. Adjust to taste gradually.

Ribs Stick to Pot

Prevent this by ensuring enough liquid—½ cup water is minimum. Also, avoid stirring the ribs during cooking. If they stick, soak the pot in warm water for 15 minutes before cleaning. Non-stick Instant Pot liners help too.
