How Long To Cook Ribs In Instant Pot
Instant Pot ribs come out tender in a fraction of the time traditional cooking methods require. If you want to know exactly how long to cook ribs in instant pot, the short answer is 25 to 40 minutes under pressure, depending on the type of ribs and how fall-off-the-bone you like them.
This guide breaks down the timing for baby back, spare, and country-style ribs. You will also get a simple step-by-step method, plus tips for finishing them under the broiler.
How Long To Cook Ribs In Instant Pot
The total cook time depends on the rib cut. Pressure cooking is fast, but ribs still need enough time to break down connective tissue.
- Baby back ribs: 25 to 30 minutes on high pressure
- Spare ribs: 30 to 35 minutes on high pressure
- Country-style ribs: 35 to 40 minutes on high pressure
- Frozen ribs: add 10 to 15 minutes to the times above
After the timer goes off, let the pressure release naturally for 10 to 15 minutes. This keeps the meat juicy and prevents it from drying out.
Why Pressure Cooking Works So Well For Ribs
Ribs are tough because of collagen in the meat. Slow cooking melts that collagen over hours. An Instant Pot does the same thing with steam and pressure in under an hour.
The sealed environment traps moisture. That means the ribs stay wet while the heat breaks down the tough fibers. No dry edges, no long oven wait.
Baby Back Ribs: 25 To 30 Minutes
Baby back ribs are smaller and leaner. They cook faster then spare ribs. Use 25 minutes for firm, sliceable ribs. Use 30 minutes if you want them very tender.
Stack them on a trivet or use a rib rack so they are not sitting in liquid. Add one cup of water or broth to the pot.
Spare Ribs: 30 To 35 Minutes
Spare ribs have more fat and connective tissue. They need a few extra minutes. Go with 30 minutes for a clean bite and 35 minutes for fall-off-the-bone texture.
Trim any large fat caps before cooking. This helps the seasoning stick and reduces grease in the pot.
Country-Style Ribs: 35 To 40 Minutes
Country-style ribs are thicker and meatier. They are closer to pork chops in texture. They need the full 35 to 40 minutes to get tender.
Because they are thick, a natural release is very important here. Quick releasing can make them tough.
Frozen Ribs: Add 10 To 15 Minutes
You can cook ribs straight from the freezer. Just add 10 to 15 minutes to the normal time. Add an extra half cup of liquid too.
Separate the racks if they are stuck together. This helps them cook evenly.
Step-By-Step: How To Cook Ribs In An Instant Pot
- Remove the membrane from the back of the ribs. Slide a knife under it and pull it off with a paper towel.
- Pat the ribs dry and season both sides with salt, pepper, and your favorite rub.
- Pour one cup of water, broth, or apple juice into the Instant Pot.
- Place the trivet inside. Stand the ribs up in a coil or lay them flat if they fit.
- Lock the lid and set the valve to sealing.
- Cook on high pressure for the time listed above based on your rib type.
- Let the pressure release naturally for 10 to 15 minutes. Then turn the valve to venting.
- Carefully remove the ribs and place them on a baking sheet.
- Brush with barbecue sauce and broil for 3 to 5 minutes until the sauce bubbles.
That last broiler step is optional, but it gives the ribs a nice sticky finish. If you skip it, the ribs are still great right out of the pot.
Tips For Better Instant Pot Ribs
Do Not Skip The Natural Release
A quick release causes the meat to seize up. The fibers tighten and the ribs get chewy. Natural release lets them relax and stay soft.
Use A Trivet Or Rib Rack
You want the ribs above the liquid, not boiling in it. A trivet or rack steams them evenly. If you do not have one, roll the rack into a coil and stand it up.
Watch The Liquid Amount
You need at least one cup of liquid to build pressure. But too much liquid can water down the flavor. One cup is enough for a 6-quart pot.
Season Before And After
Rub the ribs before cooking for deep flavor. Then add sauce after cooking for a fresh, bright taste. This two-step approach gives you the best of both.
Let Them Rest Before Cutting
Give the ribs 5 minutes on the cutting board. This lets the juices settle. Cut between the bones for clean portions.
Common Mistakes To Avoid
- Overcooking past 40 minutes, which makes the meat mushy
- Forgetting the liquid, which causes a burn notice
- Using quick release on thick ribs
- Piling ribs too high so they cook unevenly
- Skipping the membrane removal, which makes ribs tough
If you get a burn notice, stop the pot, add half a cup of water, and scrape the bottom. Then start the pressure cycle again.
Frequently Asked Questions
Can I Cook Ribs From Frozen In The Instant Pot?
Yes. Add 10 to 15 minutes to the normal cook time. Make sure the ribs are not frozen into one solid block.
How Many Ribs Fit In A 6-Quart Instant Pot?
One full rack of baby back ribs fits if you coil it. You can fit two racks in an 8-quart model.
Do I Need To Add Sauce Before Pressure Cooking?
No. Sauce can burn on the bottom. Add it after cooking, then broil for a few minutes.
What If My Ribs Are Still Tough?
Put them back in the pot with a splash of liquid. Cook for 5 more minutes on high pressure, then do a natural release.
With these times and steps, you can get tender ribs any night of the week. Start with 25 minutes for baby backs and adjust from there based on your taste.
