This instant pot ribs recipe gives you tender pork ribs that pull cleanly from the bone in roughly 45 minutes of cook time. The pressure cooker does the slow, moist work, and a short broil or grill finish gives you the caramelized edges most people want. Plan on about an hour and 15 minutes total, including prep and resting.

What You Need

  • One rack of baby back or St. Louis-style pork ribs, about 2 to 3 pounds
  • 1 cup water or apple juice for the pot
  • 2 tablespoons brown sugar, 2 teaspoons smoked paprika, 1 teaspoon garlic powder, 1 teaspoon onion powder, 1 teaspoon salt, and ½ teaspoon black pepper for the rub
  • ¾ cup barbecue sauce for finishing
  • A trivet or steam rack that fits your pot

Step-by-Step Instructions

Prep the Ribs

Pull off the thin membrane on the bone side of the rack. Slide a butter knife under one corner, grip the membrane with a paper towel, and peel it off in one piece. Cut the rack into 2- to 3-bone sections so they fit in the pot standing on edge.

Season and Load the Pot

Mix the brown sugar and spices, then rub the mixture over all sides of the ribs. Pour 1 cup of water into the inner pot and set the trivet inside. Stand the rib sections on the trivet, meat side out, curving them around the inside wall if needed.

Pressure Cook

Lock the lid and set the valve to sealing. Cook on high pressure for 25 minutes for baby backs or 30 minutes for meatier St. Louis-style ribs. When the timer ends, allow a 10-minute natural pressure release, then quick-release any remaining pressure.

Finish and Caramelize

Transfer the ribs to a foil-lined sheet pan. Brush both sides with barbecue sauce and place them 6 inches from a preheated broiler for 3 to 5 minutes, watching closely so the sugar does not burn. You can also finish on a hot grill for 2 to 3 minutes per side.

Timing and Doneness Checks

Rib Type High Pressure Time Natural Release
Baby back ribs 25 minutes 10 minutes
St. Louis-style ribs 30 minutes 10 minutes
Thick, meaty spare ribs 35 minutes 10 minutes

The meat should pull back from the bone ends by about ½ inch and bend easily when you lift the rack with tongs. If the meat still resists, reseal and cook for 5 more minutes at high pressure. The USDA lists 145°F as the safe minimum internal temperature for pork, and ribs cooked this way exceed that by a wide margin.

Common Mistakes

  • Skipping the membrane removal, which leaves a tough, chewy layer on the bone side.
  • Packing ribs too tightly, which blocks steam and leads to uneven cooking.
  • Using too little liquid. Keep at least 1 cup in the pot to build pressure.
  • Quick-releasing immediately, which can toughen the meat and make the surface wet.
  • Saucing before the broil step, which causes the sugar to scorch rather than caramelize.

  • Stainless steel trivet with handles: keeps the ribs out of the cooking liquid and makes lifting them out safer. View on Amazon

FAQ

Can I use frozen ribs in the Instant Pot?

Yes, but add 10 to 15 minutes of high-pressure time and make sure the rack is fully separated so steam reaches all sides. Thaw them first if you want more even seasoning.

Do I need to use the trivet?

Yes. The trivet keeps the ribs above the liquid, which prevents them from boiling and turning mushy. Standing the sections on edge against the wall works well when the trivet is in place.

Can I make this ahead for a gathering?

You can cook the ribs a day ahead, refrigerate them in their juices, and finish with sauce and broil just before serving. Reheat gently in the oven at 300°F if they have been chilled.

Conclusion

This instant pot ribs recipe turns a tough cut into tender, flavorful meat in under an hour of active and passive time. Remove the membrane, cook to the right doneness, and finish with a quick broil or grill for the best texture. Adjust the sauce and spice rub to suit your taste, and you will have a reliable weeknight or weekend option.
