Instant Pot Rump Roast

Instant Pot rump roast with gravy turns out moist and fork tender every time. So flavorful with every bite easily made in a Ninja Foodi too. Using a fresh beef roast is ideal but we do have instructions for most frozen roast in Instant Pot too if you need that.

Ninja Foodi Rump Roast

I think most of us know what to do with a pound of ground beef or a steak, but with larger cuts you kinda’ scratch your head. Cooking it long enough to get it tender is key, but too long you fear it could dry out. That is why using this pot or a Ninja Foodi are key to your success in the kitchen. With this pot you use the lid that isn’t attached.

If it’s left in a bit too long it isn’t such a big deal. It may just go from being able to slice it to it falling apart and creating pressure cooker shredded beef. Either one is amazing so you really can’t go wrong.

We have a lot of our most popular Instant Pot beef recipes on our site here, this is definitely one of those. This is defrosted, if you have frozen there are instructions at the top of the post for that. I suppose a lot of other people are as forgetful as I am and need these instructions too. This time we have a fresh piece of meat so you’ll want to defrost that baby before you get started on this.

Frozen Rump Roast in Instant Pot

Believe it or not if you stick to about 3 pounds the cook time remains the same, 90 minutes, to get it tender thru to the center!! That is right, whether it is fresh, defrosted or frozen solid 1 hour 30 minutes will do it. Remember that you always want to naturally release the steam at the end to maintain the moisture in your protein.

This step will take a good 15 minutes to 20 minutes so account for that when you are scheduling your dinnertime. Do not trim the fat on this baby either, that will lend more flavor to the overall dish. You can slice it off at the end if you want to. Each piece will vary slightly too, some with a large fat pad and others may be trimmer.

How many minutes per pound do you cook rump roast in an Instant Pot?

You are going to need to keep aside about 30 minutes per pound. There is a variance as far as this goes as roasts are different shapes and thicknesses for one but this is a good gage. Our 3 pound piece was great after 90 minutes so it held true in this case.

If you have only used your oven before this is going to be a real treat. A few reasons why I say that: there’s no need to tend to it and baste with juices part way thru, you don’t have to heat up your whole house to cook it. I like this pot for that last reason a lot, especially when we lived in the desert.

Of course the timing is a lot faster using this method as well. If I had to choose another way I loved beyond this one I would opt for my slow cooker or air fryer (I’ll share that one below). Those pots do all the work for you too, that is my kinda’ cooking y’all.

How to Make Gravy from the Drippings

The beauty of this is…I mean there are many but one specifically…the drippings create that wonderful gravy. It will cook in it the whole time AND then you can thicken it up and serve it on the side too. I mean as is is pretty delicious but pressure cooker gravy really takes this over the top. You just whisk together 1 tablespoon of cornstarch or flour with 1/4 cup of cold water. Add the slurry to the drippings when done and saute for 1-2 minutes, until thickened.

This cut does have a lot of flavor by itself but adding more is my style too. I love a great onion gravy when it comes to cooking easy beef recipes.

How to Add Flavor to Rump Roast

Using a dry gravy packet makes everything even easier then you can add things to it like additional fresh diced onions and additional seasonings if desired. If you wanted to add a whop of flavor to the outside you just need a bit of olive oil and you can use our tri tip dry rub to coat the top and bottom entirely before starting.

What Vegetables to Add

If you really wanted to add potatoes and carrots you could but they would need to be quite large. Since you’ll be cooking this Ninja Foodi pot roast for 90 minutes they’ll fall apart otherwise.

Petite or small Russets / red taters and carrots cut into thirds are best. Anything smaller than that and they will just become mush and you won’t want to eat them in the end. Just throw it all in and let it cook. A true dump and go one pot meal for you.

How to save leftovers

If you do have leftovers you can save them quite well to enjoy for the next 2-3 days. Only slice the pieces you will eat immediately, leave the rest whole. This will keep it as moist as possible for later. Allow to cool completely before transferring to a freezer bag.

Set in the fridge until the next day. Slice what you want to eat, pour gravy on top and reheat in microwave for about 1 minute. Alternatively you can use your air fryer but you’d want to save sauce for later that way.

If you want to use your Cosori from the get go you totally can too. Try our air fryer rump roast and see which you like better for next time.

What can I do with leftover rump roast?

I talked earlier about how to reheat it but if you want to make something else with it besides serving it on it’s own here are a few ideas: You could dice up what you have left over and make an Instant Pot casserole out of it. Combining this meat with pasta and a yummy sauce transforms it into something entirely new. Your family will never guess it was dinner last night.

• Cut it up into small bite size pieces and throw it into some fried rice too if you’d like.
• Instead of bacon, add this instead to our air fryer breakfast dish complete with eggs and all the goodness.

Same goes for our breakfast bundt cake. We have used bits of ham left over after Christmas in this, bacon, or any type of beef that needs to get eaten. If you are throwing a brunch for family it is always a hit since you can serve all the food groups in this pretty cake form.

What do you use your leftover beef in? I am always looking for new and novel ideas to change things up. I HATE wasting food so I love finding something new we haven’t tried yet and keeping it in my Rolodex of ideas for the future. (okay that term probably ages me but if you’re in your 40s + you know what I mean by that term) 😉
