What is the best cut of roast?

A boneless chuck roast is the best choice for pot roast, quite inexpensive too. It has outstanding marbling which makes the beef tender and juicy when cooked in any method really. Remember that fat=flavor so don’t choose a piece that is lean (those can be more expensive anyway).

Can you cook a frozen roast?

I actually wasn’t so sure this would even work and wondered can you cook a frozen roast without defrosting it first and still have it come out tender? The answer was a resounding YES! The trick is high pressure AND allowing the steam to naturally release slowly which will continue to break down the connective tissues so it is fork tender.

• Beef, pork, and lamb roasts are safe to cook in the frozen state. The only real big difference is that the cooking time.
• Frozen meats typically take 50 percent longer in the oven, but not in a pressure cooker.

That’s the game changer. Now you can cook an Instant Pot chuck roast from fresh or a frozen state and have it come out perfect! Of course if it’s already defrosted it is quicker to do. Follow our directions Instant Pot beef roast recipes if it’s fresh.

How long to cook 3 pound frozen roast in Instant Pot

90 minutes was perfect for this size. Of course yours may not be exactly this size but you can adjust it rather easily with about 10 minutes per pound with this in mind meaning; 2 pound frozen roast = 80 minutes cook time & 4 pound frozen roast takes 100 minutes to pressure cook.

What is one of the most important steps when making an Instant Pot pot roast, or any large piece of meat?

• When you cook a roast in a pressure cooker it is best to do a natural release of the pressure once the cook time is up.
• Following this rule will keep your meat much more tender and almost fall apart when touched with a fork.
• If you choose to quick release it instead a lot of the moisture inside will escape and you won’t achieve the outcome you want.

This step may take about 20 minutes to 30 minutes to complete, beyond the cooking time, but is well worth it.

Can you cook a roast partially frozen?

Yes, even half solid I would follow the same timing though. These are the steps to follow when making this pot roast recipe here. We now have frozen pork roast Instant Pot directions too! Any large cuts have a great result this way. Actually, the longer it cooks the more tender it gets so it is hard to mess up. 😉

First of course you will want to unwrap your piece of protein. Since it is frozen you won’t be able to trim it at all but that is okay. For this type of meat you really want the fat in tact because it will make it more moist in the end.

1. Place a trivet inside your pot with your frozen roast on top.
   1. remember that timing below is based on a 3 lb. piece
   2. if yours is much larger than that you may need to increase a few minutes on high
2. Pour your broth or stock on top followed by a sprinkle of your sliced onion.
3. Sprinkle any and all seasonings you like on top now.
   1. the ones we have are just suggestions, if you usually use your own mixture go right ahead and load it on.
   2. you can also just use these ready made roast seasonings in a packet. These were originally made for the slow cooker but work great using this method as well.
4. Close lid and steam valve and set to high pressure for 90 minutes followed by a natural release.
5. Lift meat out, allow to rest for 10 minutes before slicing or shredding.

If you want to make a gravy out of the drippings, follow our Instant Pot gravy directions.

How long does it take to thaw a frozen roast?

Want to try this another time defrosted? I mean the outcome is a bit better if you have the time to thaw it in the fridge overnight to make pressure cooker shredded beef inside slider buns for a one pot meal.

• You can put your frozen roast in the refrigerator for one to three days to soften. If it is rather large it may take up to five days at the most.
• A 4 pound piece takes about 24 hours to thaw, but sometimes longer so plan for a little over a day when you’re meal prepping.

How do you defrost meat?

To defrost a piece of beef in cold water, do not remove the outside packaging. Be sure it is on there airtight or put it into a freezer bag free of leaks. Then, just submerge the meat into a bowl or sink full of cold water. Make sure to change the water every 30 minutes so that it continues to thaw. Small packages may defrost in an hour or less whereas a 3-4 pound roast may take 2 to 3 hours

Sliced or shredded it is always a great meal option because there is a multitude of ways it can be served like: Then you could follow one of our easy Instant Pot beef recipes.

1. Served over a bed of pressure cooker mashed potatoes
2. With a side of Instant Pot carrots

How long is leftover roast beef good for?

If you store it properly in airtight containers or freezer bags, cooked beef roast will last for 3 to 4 days in the refrigerator. You can make an Instant Pot casserole with it, or dice it up into a batch of pressure cooker fried cabbage.

• If you know you won’t eat it all before then, you should freeze it in covered containers free from leaks or wrap tightly with aluminum foil or freezer wrap.
