Can you make a prime rib in an Instant Pot?
If the recipe title hasn’t given it away already… Yes, you can! You can make the perfect prime rib. Tender, cooked at just the right temperature, and full of flavor.
The Instant Pot may just be the best way to cook prime rib. It frees up space in your oven and makes everything from the rib roast itself to the gravy as easy as can be!
I love trying new things! After making Slow Roasted Prime Rib, a Boneless Prime Rib Roast, and a Standing Rib Roast all in the oven, I can safely say that cooking it in the Instant Pot is my favorite way to save on time and space in the oven.
Best Prime Rib Cut
We recommend looking for a boneless rib roast with plenty of marbling.
Marbling refers to the streaks of fat and white flecks in a cut of beef, and it adds tons of flavor to a rib roast! For the best marbling and flavor, use a Certified Angus Beef® brand cut.
“First recipe I tried in my brand new IP and it did not disappoint! Hubby has added this to the repeat list.” — See the Pinterest Review
Prime Rib Rub
All we use to season our dish is salt and pepper. For a beautiful roast like this, you don’t need more than that!
Can I use a bone-in roast?
We do not recommend using a bone-in roast to make this recipe. The cook time will not be the same as boneless, so we recommend only using boneless.
Can I use a larger cut?
Yes! Follow these cook times:
- 4 lb. roast: +1 minute to the pressure cook time
- 5 lb. roast: +3 minutes to pressure cook time
Prime Rib Gravy
This recipe calls for all-purpose flour for the purpose of making a gravy from the drippings. Homemade gravy is easy, delicious, and adds so much flavor to the dish!
- When done, remove the roast to a platter, tent with foil, and let it rest for 15 minutes.
- Add the strained liquids back to the pot, then add 3 Tbsp. all-purpose flour and stir to make a gravy.
Prime Rib vs Ribeye
The difference is that prime rib is a larger cut of beef serving as a roast, while the ribeye is a smaller cut of beef serving as a steak.
Both the ribeye and the rib roast come from the same section of beef. In fact, ribeye is cut from the rib roast.
Both are juicy, delicious, and some of the best cuts of beef available. You have got to try our Reverse Sear Ribeye Steak, you will know exactly what I mean.
⭐ Prime Rib Instant Pot Tips
- Reverse seared prime rib makes it easy to cook your rib roast to the perfect temperature while maintaining a beautiful crust on the outside!
- Beef stock vs red wine: If you would prefer, you can substitute the red wine for additional beef stock.
- Meat thermometer: Always use a meat thermometer to achieve your desired degree of doneness.
- Let it rest: Always let the roast sit for 15 minutes before carving. This helps lock in the flavor.
- Slice against the grain: For the most tender prime rib, slice against the grain.
Prime Rib Temperatures
- Rare: 125°F
- Medium-rare: 135°F
- Medium: 145°F
- Medium-well: 150°F
- Well done: 160°F
Make sure to use a meat thermometer for accuracy.
How long do I cook Prime Rib in Instant Pot?
Leave the roast in the pot for 30 more minutes after the initial cook time at pressure. The Instant Pot will automatically switch modes to the “keep warm” setting.
Once 30 minutes are up, open the pot and insert a meat thermometer at the thickest part of the rib.
The meat thermometer should read approximately 115°F. If the temperature is too low, put the lid back on and leave it on warm for 5 to 10 minutes longer, then check again.
👪 How Much Prime Rib Per Person
This recipe will serve about 6 people if you are serving ½ an lb. of roast beef per person, or 4 if you serve larger portions.

Leftover Prime Rib Ideas
Our absolute favorite recipe for leftover prime rib is this Creamy Penne Pasta with leftover prime rib slices.

Or you can slice it up thin and make a Hot Roast Beef Sandwich with Caramelized Onions out of it with our remoulade sauce. I dream about this sandwich.

Reverse Sear Instant Pot Prime Rib
🍳 Equipment
🥘 Ingredients
- 3 lbs. boneless beef rib roast
- sea salt to taste
- black pepper to taste
- 1 cup unsalted beef stock
- ½ cup red wine Merlot, shiraz, pinot noir or your favorite red wine
- 3 Tbsp. vegetable oil
- 3 Tbsp. all-purpose flour
- optional: sprigs of fresh herbs we recommend rosemary, thyme, or parsley
🔪 Instructions
- Score the fat cap of a 3 lb. boneless beef rib roast.
- Generously season your roast on all sides with sea salt and ground black pepper. Give it a good coating, even if it seems like too much salt. Trust us, you want to coat it all over!
- Place the trivet in the Instant Pot. Place the roast in the trivet. Add 1 cup unsalted beef stock and ½ cup red wine.Optional step: Add a few sprigs of fresh herbs to the Instant Pot, such as rosemary, thyme, or parsley.
- Lock the lid in place and make sure the vent is in the “sealing” position. Choose the manual setting, low pressure, and set the timer for 5 minutes.Once the 5 minutes is done, do not remove the lid or release the pressure. Leave the roast in the pot for 30 more minutes. The Instant Pot will automatically switch modes to the “keep warm” setting.
- Once 30 minutes are up, open the pot and insert a meat thermometer at the thickest part of the rib. As always, be careful when removing the lid.The meat thermometer should read approximately 115°F. If the temperature is too low, put the lid back on and leave it on warm for 5 to 10 minutes longer, then check again. When searing, the temperature will rise, so you want to pull the prime rib out of the pot early (before it cooks to your desired temperature).Remove the roast to a plate. Strain the liquids from the Instant Pot into a cup, and set aside.
- Remove the trivet from the Instant Pot. Select the highest saute setting. Add 3 Tbsp. vegetable oil to the pot. Place the prime rib roast back and sear it until it browns on all sides, approximately 10-15 minutes. The prime rib should have a nice crust on it. If you prefer, you can brown the roast in a cast-iron skillet on the stovetop.
- Insert the meat thermometer into the thickest part of the prime rib and make sure you cook it to your desired degree of doneness. For quick reference, the temperature for medium-rare prime rib is 135 °F and 145 for medium.Remove the roast to a platter, tent with foil, and let it rest for 15 minutes.Add the strained liquids back to the pot, then add 3 Tbsp. all-purpose flour and stir to make a gravy.

Lisa says
My store was out of unsalted beef stock so I have the salted. Would you recommend omitting the salt from the tub completely or just cut it down?
Em Beitel says
Hi Lisa! That’s no problem! Just cut down the salt a bit on the prime rib and it will be fine. Thank you so much and please enjoy!
Rob says
Amazing! I made this on a weekday (workday) and it was perfect. Thank you so much.
I had to substitute Better than Bullion broth for no-salt broth, and I used Montreal steak rub as well, and the gravy was perfect.
It’s nice to know prime rib is not just for Christmas and New Years in our home now.
Em Beitel says
Rob, thank you so much for your lovely comment! We’re so glad to hear you enjoyed it and your substitutions sound perfect!
Thi says
Hi. I’m only cooking for two people so would like to use a 2lb prime rib if I can find one. Would I change any times in the recipe if I’m using a smaller cut? Please advise. Thanks.
Em Beitel says
Hi, Thi! Our recommendation would be to just remove a minute from the pressure cook time and cook for 4 minutes instead of 5. Then follow the recipe as instructed. If you check the temperature after letting it sit in the pot and it still needs a bit more time, just leave it in for a bit longer until it comes to temperature. Thank you for your question!
Bronwyn says
This was incredible! I made it tonight. I used a 2lb, bone-in prime rib roast. I left the bone in, and it still turned out great. Only modification was that I rubbed some homemade garlic butter on it prior to putting it in the IP. Would recommend this recipe!
Em Beitel says
Bronwyn, thank you so much! That sounds wonderful and we’re so glad you enjoyed it! Garlic butter is a great choice. 💖
Emily says
Do you think salting it 24 hours in advance would change the cook time? And if I want it well done should I increase the cooking time to like 7 mins?
Thank you!
Em Beitel says
Hi Emily! No, salting it ahead of time shouldn’t change the cook time. If you want it well done, 7 minutes should do the trick, but if you find it’s still not quite where you want it you can always leave it for longer in the pot on warming mode or put it in for another minute. We can’t wait to hear how you like it – thank you so much for your comment!
TIffany says
If I have a 8.5 to 9 pound cut do I need to increase the cooking time?
Em Beitel says
Hi Tiffany! We would not recommend cooking a roast of this size in your Instant Pot. We have a Slow Roasted Prime Rib that is perfect for a roast of this size and super easy to make. You can find it here: https://sundaysuppermovement.com/slow-roasted-prime-rib-recipe/. Thank you for your question!
1ChocolateLady says
Hi, does a bone in prime rib need to cook longer? Mine is 5.7 lbs and it just fits in my instant pot!
Em Beitel says
Hi! We recommend not cooking a bone-in prime rib using this method – it will take longer and we can’t guarantee the cook times will be the same for bone-in. Thank you for your question!
Fe says
Hi! I was only able to find a ribeye roast.. I know you called out the differences but would I be able to still follow this recipe with that type of cut? Thanks!
Em Beitel says
Hi Fe! We’re sorry for the confusion – ribeye roast is the same as prime rib roast! Hope you enjoyed. Thank you!
