Instant Pot Frozen Pork Roast

Are you forgetful? Me too. I have those days when I am non stop in my car and often times I don’t think ahead in the morning to defrost dinner. NO problem my friends.

I share how to “fix” many of these mistakes, this is just one more that will likely help you in the event of your next uh oh moment. 😉 This is what you are going to need to make this meal successful;

1. I used a frozen pork loin roast that was 2.5 lbs. Timing will reflect that weight, I would say up to 3 lbs. would be the same.
2. Chicken broth is better than using just water, apple juice is another option.
3. Salt and pepper are a given but other seasonings you love could be added as well.
4. A sliced red onion was thrown in there, optional of course.
5. You’ll need a trivet for this as well.

Bay leaves were a nice touch, remember to take those out before making your gravy with the drippings.

How long does it take to cook a frozen pork roast?

It depends on what method you use. In the oven it takes about 45 minutes per pound which is almost double in a pressure cooker. You can use a Crockpot Express or Ninja Foodi to make this the same way too.

Instant Pot Pork Roast Frozen

This is a great recipe especially if you buy meat in bulk online or from local farmers like we do every year. Then whether it is fresh, defrosted or rock solid it will come out great every single time.

Without a bone it cooks faster than if you had a pork butt or frozen pork shoulder. I have had success with those as well but this is quick and easy because there’s nothing to remove.

You’ll need to use the pressure cook button on high if your pot doesn’t have the meat/stew function. They are the same except that the latter automatically sets to 35 minutes unless adjusted.

One big tip to remember when figuring out the Instant Pot cooking times for meat is that you need a natural pressure release when done. This is important so that the inside remains tender and doesn’t dry out.

Whether you’re cooking pork or beef it is important for both. This allows it to become fall apart delicious just like a slow cooker would. It may take 20 minutes to 30 minutes for all the steam to release so you can remove the lid.

Be very careful once it’s lifted and face it away from you once it is taken off. Don’t drain all that wonderful liquid though when you remove the protein, you’ll want it to make pressure cooker gravy.

Use just a bit of cornstarch whisked into the hot liquid to thicken it up. Push saute and allow it to bubble together for about 2 minutes and then it will be done and ready to enjoy.

Turn pot off and pour gravy into dish so it doesn’t continue cooking. Taste it and adjust the salt and pepper to taste before pouring it over each piece. OR shred it and turn into Instant Pot pork tacos.

What temperature should I cook a pork roast?

Of course you should always check meat internal temperature in the center before consuming to ensure it is safe. It should be 160 F degrees with at least a 5 minute rest time. I usually allow it to sit for 10-15.

What do I serve with pork roast?

The possibilities are endless really but we always offer vegetables like sweet potato cubes or corn on the cob. Rolls are easy, I usually buy those at the store already baked to make things as easy as possible.

It saves really well too. Just slice what you want to eat, leave the leftovers whole and wrap in plastic wrap. Then slide into a freezer bag and refrigerate. To reheat first allow to reach room temperature for about an hour. Pour gravy on to each slice and microwave for about 1 minute.

Looking for another idea like this one? Try our pork butt in Instant Pot (frozen pork butt Instant Pot instructions) or Instant Pot frozen pork loin too.

I often times dice it up and throw it into some fried rice the next day. You can add it into an Instant Pot casserole too in order to add some meat to the pasta and sauce.

Warm, slice and serve it on top of a bed of mashed potatoes or rice the next day too. It works great in a number of other dishes that just need some protein.

If you have beef next time, you can follow our Instant Pot frozen chuck roast recipe too. Using salsa verde you can pull it at the end to make tacos and/or sliders.
