💭 Things to know
Expert Tip: Although some pot roast recipes don’t tell you to sear the meat before adding it to the
- If possible, let your meat sit out at room temperature for a half hour before searing. Cold meat that’s cooked straight out of the fridge will cook unevenly.
- Pat your roast with paper towels before seasoning. Removing excess moisture helps the dry rub stick better and prevents oil splatters.
- To make a thicker gravy, create a cornstarch slurry with a cup of the cooking liquid. Then, stir the mixture in and let it simmer.
- Deglaze your skillet with the beef stock or a little water and scrape all those flavorful brown bits into your
slow cooker . Yum! - Although I prefer to thinly slice the meat at the end of the cooking time, you can also shred it with forks or cut it into large chunks.
- It takes anywhere from 8-10 hours to cook your rump roast at a low temperature. However, larger roasts may need longer cooking time.

The best cuts of beef for a
The main difference between these two cuts of beef is where they come from. The rump roast is from the top of the rump of the cow, while the chuck roast is from the shoulder. Rump roast is a lean cut of beef compared to chuck roast.
Although you can cook your rump roast on high for 4-5 hours, I don’t recommend it. After all, slow-cooked meats are more tender!
Yep! Follow the original recipe, and then cook the roast in your sealed InstaPot at high pressure for 20 minutes per pound of meat.

I know y'all don't always like the stories bloggers tell so when I have one I try to put it at the very bottom so you can read or skip as you like.
Rump roast is what Sunday dinners were made of. When you see those gorgeous images of plates of beef and gravy, mashed potatoes on the side?
Rump roast.
The first time I made this dish I was newly married, just shy of my 20th birthday, and without much cooking experience. My family life, growing up, was unique - and not something I necessarily wanted to emulate so I hungrily watched Father Knows Best, Leave It to Beaver, and other mid-20th century sitcoms to see how it should be done.
My husband was in the military so when he'd go to work at 4 am I'd cook like crazy until I came up with something edible, then I'd throw out everything that didn't work by 12 noon so the kitchen looked and smelled normal by the time he walked in the door.
I wasn't sure about many things but I knew that families were supposed to have Sunday Dinners and I was determined not to be outdone by Mrs. Cleaver.
I decided roast beef would be the perfect way to show off my newly formed cooking skills.
I wasn't sure how much meat to buy, but he ate a lot so I decided 4 pounds looked about right for the two of us. I followed the recipe carefully and, lo and behold, it smelled (and tasted) amazing when it was done.
It was just that I had to make him drive back to the base and pick up 6 of the unmarried guys because apparently, 4 pounds of beef feeds a lot of people.
A lot.
