Save Time Cooking Pot Roast in the Electric Pressure Cooker
Using an electric pressure cooker saves time. It takes just a little over an hour to cook a pot roast in the pressure cooker. If you use a slow cooker it can take 7 to 8 hours. If using an oven it takes about 3 to 4 hours. It takes just over 1 hour of cooking time to make a pot roast in an electric pressure cooker.
How to Cook Mississippi Roast in an Instant Pot
Cooking Mississippi pot roast in the Instant Pot is an incredibly easy process. I am going to show you step by step how to do it so you end up with that slow cooked tender beef pot roast and the delicious gravy in much less time than using a crock pot or oven.
Step 1 – Cut Pot Roast into Chunks. This allows for a much better sear and added flavor. The reason is by cutting is into cubes you can sear the beef on all sides adding flavor and texture. This was just about a 3 pound chuck roast.
Step 2 – Turn on Saute Mode and Sear. Press “Saute” Button until the screen it at the “HIGH” setting. Somer of the older Instant Pots say “More.” When the screen says “Hot” it is ready to sear. Pour in Oil and give it a chance to heat up. Place in your roast. Try to get a bit of space in between pieces for a better sear. Do not touch for 5 minutes.
Step 3 – Flip and Sear on all Sides. After the initial 5 minute sear on the first side flip and repeat for another 5 minutes. Do this on all sides for maximum flavor. If you have a larger roast this may need to be done in batches.
Step 4 – Remove Meat and Deglaze. Once all of your meat is seared remove and keep warm. If using onions which I recommend since it adds more flavor add them to pot and sauté for 1 minute. Deglaze the pot bar pouring in about 1/4 cup of the broth. Scrape the bottom of the pot to release all the bits from the pot.
Step 5 – Add Seasoning packets Broth and Brine. Add the beef broth, ranch seasoning and au jus seasoning and the brine from the pepperocini jar. Stir to mix everything up. Return the meat to the instant pot and place the pepperoncini peppers on top.
Tip: I like to make sure that the liquid is halfway up the sides of the meat.
Step 6 – Pressure Cook Mississippi Pot Roast. Place the lid on the Instant pot and move the valve to the sealing position. Pressure cook Mississippi pot roast 50 to 60 minutes cook time depending on size of roast. When the cooking cycle ends do a 15 minute natural release and then quick release remaining pressure.
Step 7 – Making the Gravy. Remove the chuck roast from the Instant pot and set aside on a plate under some foil to keep warm. Press cancel on the Instant Pot and then select Sauté setting. While the beef broth mixture is heating up mix together the softened butter and flour in a bowl until combined.
When the liquid in the Instant Pot is bubbling add the butter flour mixture and stir constantly to get everything combined and avoiding lumps. When everything is combined let gravy mixture simmer 2 to 3 minutes until thickened. If you want it thicker let it simmer a few more minutes.
How to Make Mashed Potatoes
When I was making this Mississippi pot roast I was going to have it with these mini potatoes and then I thought to myself that this dish would be much better with mashed potatoes. It turns out that these mini potatoes make great mashed potatoes and you don’t have to peel them.

- Place potatoes in a pot and cover with water.
- Turn to Medium High until water is boiling
- Boil potatoes about 20 minutes until tender when poked with a fork.
- Remove from heat and drain water.
- Place lid on pot for a couple minutes to dry the potatoes.
- Add 2 Tablespoons butter and put lid back on to melt butter.
- Once butter is melted add about 2 Tablespoons Half and Half.
- Mash potatoes with potato masher until combined and at your desired texture.
- If they are dry add a Tablespoon more Half and Half
- Salt and pepper to taste.
Can A Frozen Roast Be Used?
Yes a frozen roast can be used but you will have to skip the searing of the meat step which adds flavor. The other drawback is you will not be able to just the pot roast into chunks so the cook time will be longer.
Can Veggies Be Added?
Yes veggies can be added to Mississippi pot roast. Since the cooking time for the roast is about an hour I would not add the veggies directly to the original cook time. I would wait till after everything is cooked and pressure is released and roast has been removed. I would place in the veggies and cook them BEFORE making the gravy. The pressure cooker will come to pressure quickly since it is already hot. Follow times below and cut the veggies into larger pieces.
- Carrots 4 minutes High Pressure
- Potatoes 4 Minutes High Pressure
- Green Beans 1 Minute High Pressure
What Kind of Beef Can Be Used?
I always use a chuck roast but bottom round roast, top round roast, rump roast and sirloin tip roast are a few other cuts of beef that could also be used to make this Mississippi pot roast.
How to Make Mississippi Pot Roast in a Slow Cooker
- Heat oil in a skillet over Medium High Heat
- Sear the beef cubes on all sides. About 5 minutes each side.
- Remove the beef and set aside. Deglaze the pan with some of the beef broth or brine from the pepperoncini peppers.
- Add broth, ranch seasoning and au jus gravy packet to the slow cooker. Onion soup mix can also be used. Stir to combine.
- Add the beef cubes to the slow cooker and top with pepperoncini peppers.
- Slow cook on High for 4 hours or 8 hours on Low.
- Mix together 2 Tablespoons cornstarch and 2 Tablespoons water.
- Remove beef and add cornstarch mixture to slow cooker and let thicken for 20 minutes.
- Add pot roast back to the slow cook and coat with the sauce.
How to Serve Pot Roast
I think the best way to serve this pot roast is over mashed potatoes. This is just pure comfort food to me. I sometimes serve it over rice which is also delicious.
Substitutions
- Onion Soup Mix – A packet of onion soup mix can be used in place of ranch seasoning packet.
- Banana Peppers or Hot Cherry Peppers – can be used in place of the pepperoncinis.
Even if your reader doesn’t follow a specific diet (eg. gluten free), they may have friends or family that they’re cooking for that could use this. This is also a great idea to link out to another blogger with a similar recipe that fits a different diet.
Reheating and Storage of Leftovers
Leftovers can be stored in an airtight container in the refrigerator for 3-4 days.
If wanting to freeze leftovers a nice space saving tip is to put the roast in a zip bag and lay them flat in your freezer.
Reheating in the Instant Pot – Place 1 cup water in the pressure cooker. Place pot roast in glass or metal dish that fits in the Instant Pot. Place dish on top of trivet. Press “Steam” button and set time for 15 minutes.
Reheating in the Oven – Place pot roast in an oven safe dish with a small bit of broth or water and cover with foil. Place in a 350 degree oven for 15 to 20 minutes.
