How To Choose The Right Cut Of Meat

Pot Roast isn’t a specific cut of meat – its more about the cooking method.  You basically take a large chunk of tough meat and cook it with liquid (often broth, red wine, or water) until it is falling apart tender.  A few cuts of meat that work great for Pot Roast are:

  1. Chuck – this cut is from the front part of the animal.
  2. Brisket – this cut is from the breast or lower chest of the animal.  Be sure to slice against the grain for tenderness.
  3. Round – this cut is from the rear leg of the animal.  This is often called a rump roast or a bottom round.

How to Make Instant Pot Roast Beef

  1. Start by taking your frozen roast beef and placing straight into the instant pot. Rub it with salt and pepper, garlic and herbs. Add onions around and on top. Place 3 cups of beef broth and seal lid, setting valve to close.
  2. Cook roast for 90 minutes high pressure, natural release. I always refrain from a quick release when cooking meat – a natural release is the only way to go with pressure cooking roast beef – it leaves it fork tender. This pressure cooker frozen roast beef came out perfectly pull apart tender.

How to make pressure cooker gravy

  1. After the roast has completed cooking set it aside. Remove onions and other solids from broth. Using  saute setting on your pressure cooker, bring liquid to boil. (You can also remove the broth/drippings and place in a sauce pan to make the gravy over the stove-top.)
  2. In a sperate bowl mix flour and cold water together and slowly whisk it into the boiling broth until it reaches desired consistency. Taste, and add salt and black pepper to your liking. This pressure cooker gravy is so tasty and delicious!

How to make pressure cooker potatoes and carrots

  1. After roast and gravy are done you can make potatoes and carrots so fast also! Or you can purchase a second instant pot- I have a smaller 3 qt pot that I love to cook my side dishes in.
  2. Add potatoes and carrots to instant pot with 1 cup water and some salt. Cook for 4 minutes high and quick release! Don’t natural release these bad boys or they will be too soft. Drain water, separate if desired and mash the potatoes or serve them all up as is with the pressure cooker gravy!
  3. We have recipes more recipes for pressure cooker potatoes (mashed potatoes here and red potatoes here) and carrots too!

Either way pressure cooker potatoes and carrots with this pressure cooker frozen beef roast is fast and easy!

  1. We just got one a few weeks ago. Had an old one for years. Excited to do some canning. Nice job. Haven’t put anything frozen yet. Not a fan of what yours looked like a pulled (like pulled pork) Thanks for posting !!

  2. Thank you for all of your careful directions. Sure helped me when I made my first frozen roast today. Your roast needs some of that delicious gravy on the plate. Looking forward to trying some of your other recipes.

      1. Please help im making this now lol! What setting do i set my instan pot to? Slow cook? Meat/stew?

        1. press the manual button and cook it on high pressure! if you ever need us asap also try contacting us on facebook or instagram we are usually pretty fast there to respond. :)

      2. Tried recipe with 4 1/2 frozen bottom round snd its cold and raw in the middle after 90 minutes. Put it back in for addit 30 minutes.any Recommendations?

    1. Yes! I have a power pressure cooker, not an instant pot, and I can only set mine to a max of 60 minutes. But if the instant pot will do 90, go for it!

  3. I had prepared some potatoes;o cut into quarters. As it was frozen roast; I was making the gravy. I swelled all potatoes into the pressure cooker with water and salt for 8-10 minutes. Soft and mashed with plenty of butter, milk, and salt. WOWs it`s wonderful dishes ever I have a taste. You can visit our websites to get more and new recipes.

    1. The instant pot is a digital pressure cooker! There are many different brands out there making it now, like pressure cooker XL makes a quality pressure cooker too. These are different than the old version where you use the pressure cooker on the stove top and bring it to a whistle. The digital pressure cooker allows you to set a timer so your food/temp/recipe is more precise. They are awesome, we highly recommend them.

      1. My pressure cookeR not a instant pot,just a small brand BESTEK. Cook with pressure cooker is amazing!Healthy and quick..I use it to do potatoes, stews and lately I cut up a whole chicken with a carrot, onion and celery and cook it for about 30 mins, then I take out the chicken and pick off the chicken for a big curry or sweet and sour dish and use the liquid remaining as a chicken stock for soups or stews.Pressure Cooker is a good choice for those who don’t like to use pan to cook.

  4. I just bought an Instant Pot yesterday. I’m going to try the frozen pot roast today. I’m so exciTed to start cooking in my cooker!!! Thanks for the recipe and step by step instuctions!

  5. Used this recipe on a venison roast and it was tender, juicy and delicious. Venison roasts dry out so Easily but this approach made the most moist venison roadt ive ever had. Love the instant pot! Thanks for sharing this reCipe. . (Also loved the red pepper flakes and the little Extra that added).

    I got a power pressure cooker xl and have enjoyed it very much. I play around with different ingredients and settings. I am glad that i gave it a chance, as i am very satisfied. Thank you for sharing your reciepe. i tweaked it a bit. Always fun!!

    I used thIs recipe to cook a frozen 3# bottom round roast in my Instant Pot. Followed the recipe except for a COUPLE of changes. I seared all the sides of the roast first & cooked it for 50 minutes, did a qr, put my chunks of potato & carrots in with the roast, then cooked for another 20 minutes. Let it do a nr. The roast was done, tender & flavourable & the veggies were done perfectly as well. Using the onion soup mix along with the salt & pepper gave the gravy a fabulous taste. Thank you for providing a recipe with good directions. Its not easy finding a recipe for cooking with frozen meat.

    Made this last night and it was delicious! I was honestly nervous because I’ve always taken hours to make the chuck roast in the oven. I was short on time and the meat was still frozen so I took the chance on this recipe and I’m so glad I did! I used beef broth instead of water which made the gravy even tastier. I served this was mashed potatoes and then roasted green beans and carrot sticks. For the veggies i just peeled and cut carrots into sticks then put them in a bowl with the beans, drizzled/mixed with olive oil until lightly covered, sprinkled with sea salt, pepper, and a tiny garlic powder, then roasted in the oven (one layer) at 350 for about 20 mins!

    1. also, my cut was 2.7 lbs untrimmed. I probably put just a tad more liquid in there because the meat was just a bit more than half covered. I did the whole 90 mins and it came out perfect. lastly, unfortunately I am not a fan of all.. but being on a time crunch i WENT AHEAD AND USED THE MIX FOR THE FIRST TIME AND IT DID NOT HAVE A STRONG ONION TASTE AT ALL! it was just perfect! so for those of you like myself i suggest giving it a shot!

    Thank you SO much for This post. I just received my pot and there were no I instructions for starting frozen. The pot roast was delicious!

  10. I made this tonight……amazing! There was little CONVERSATION at the dinner table…..we were Too busy enjoying our meal!

        1. Hi Jen, This recipe is for the pressure cooker, not slow cooker. It is also instructions for a frozen roast, so it does need to cook longer than a fresh roast :)

    I started my insta pot and only put in 1 cup of liquid, then i found Your recipe. My roast is frozen. Do i need to qr and add more water, And then finish cookinG, or will i be fine? It is 2.72 pounds and i have it set for 99 minutes. The last few times it has taken longer to cook. Maybe its the amoUnt of liquid and The Qr release at the end that is making the difference. .

    1. If the roast is under 3 lbs, cooking it for 90 minutes with 1 cup of water) 1and letting it natural release will be good! Sometimes, depending on your altitude you might need to alter you cook times to longer.

    1. Hey Summer! Thank you for pointing that out. I just add what my family will eat, or even what will fit in the instant pot you have with all the food already in it, there isn’t a specific amount. I recommend 4-6 carrots whole carrots, chopped into about 2-3 pieces. I’ve adjusted the recipe card.

    I JUST made this recipe and I have to say I was a bit skeptical about the cook times for the beef roast — because I have read a lot of different recipes and the cooking times have varied from 45 to 90 mins — for basically the same weight of meat. Having said that though, I followed the recipe and it came out “OH, SO DELICIOSO!!” I haven’t had a lot of experience with pressure cooking and I have only cooked a few things — I have an Instant Pot — but the things I have cooked have been just great! My only negative comment would be that my gravy doesn’t look like the one in the picture — :(. I had sooo much broth in my pot and I followed the gravy recipe and even added an additional 1T of flour to the 1T of water to the broth and still it looked pretty much like broth, but regardless of that, I am VERY HAPPY/PLEASED with this recipe and would HIGHLY RECOMMEND it!! :)

    Thank You,
    Mary Beth

    Just made this yesterday. I was so nervous cooking a solid frozen chuck roast. I cooked it on the trivet. Cooked on high for 90 minuets with a 20 minuet natural release. It turned out perfect. It was approx. 3 1/2 lbs.

  14. 5 stars
    Just finished supper. The meat was made from frozen (2 lb roast) but I think next time I will try it with a thawed roast. I found the roast really didn’t have a lot of flavour, the rest of the meal turned out perfect. I did 1/2 potatoes and 1/2 yams. turned out delicious. Gravey was yummy. Roast like I said, lacked flavour. I think when frozen it is really hard to rub it with salt. Thanks for the recipe.

  15. I tried this recipe tonight. Total bust! I can’t figure out why every time I try to cook a roast in my Instant Pot it’s dry and tough. I’m pretty sure it’s something I’m doing wrong.

    1. I’m sorry. I’ve had this happen with various recipes- sometimes they turn out great other times not to great and I cooked them the same. One thing to consider it the cut and quality of meat, Especially roasts.

    2 tablespoons of salt seems excessive so I halved that, as well as the red pepper (my kids don’t love the heat). Had to make some substitutions for the dairy in the potatoes, but despite that, it all turned out delicious!! And this is my new fav way to make mashed potatoes. 4 min in the instant pot?? Come on!!!

  17. I was going to make this yesterday with a frozen roast but misplaced the steam cap to the Instant Pot. I am making it today but will need to adjust the time, since the roast is now thawed. How long would you cook it for?

  18. 5 stars
    I made this tonight and it was to die for. Instead of beef broth I add a quart of home canned tomatoes and Worcestershire and soy sauce with a brown sugar rub and bouillon cubes. Then made the gravy with mashed potatoes and home made canned applesauce. Yum yum

  19. Does anyone know why some recipies for frozen roasts in IP say to put meat on a trivet, and others like this one put it right in the pot? I’m making this now, increased cook time because my roast is a little over 3lbs. I put it right in the pot with the broth, and then started reading other recipes that say to use a trivet.

    Thanks for the recipie! Glad I didnt have to wait to defrost my roast :)
