How to Make Slow Cooker Mississippi Pot Roast

What Cut of Beef is Best for Mississippi Pot Roast?
When making pot roast, there are a variety of cuts of beef you could use including ground chuck, brisket, top round, bottom round, and rump.
However, I use boneless chuck roast for Mississippi pot roast in the Crockpot and that is what I recommend since that is how I’ve tested the recipe with picture perfect results every time.
Do I Have to Use Onion Soup and Ranch Seasoning Packets?
I have only made this Crockpot Mississippi pot roast recipe using onion soup mix and ranch seasoning mix and don’t deviate because it turns out perfectly when using them!
They combine with the natural juices from the meat when cooking and form the most perfect au jus, or sauce. The packets are readily available for most North Americans, add a ton of flavor, and help to season the Mississippi pot roast to perfection.
If you live in an area where these convenience packets aren’t available or you have an aversion to using seasoning in packets, feel free to research for how to adapt the recipe as you see fit.
Should Crockpot Pot Roast Be Cooked on Low or High?
You can make this easy pot roast in your slow cooker on either the low or the high setting, although I tend to prefer the low and slow method for a better final result.
On low, the roast will need 8 to 10 hours. Whereas on high, it will take 4 to 5 hours to cook. Because all slow cookers and cuts of meat vary, make sure to cook as long as necessary until it’s done.
Tip: Do NOT open the lid, stare at your Mississippi pot roast wondering what it’s doing, allow all the steam to escape; and repeat every hour. It will just slow the cooking time and process down, and doesn’t do anything positive. Gaze at your little bun in the oven through the glass lid of your slow cooker is my advice.
What to Serve with Mississippi Pot Roast
Not sure what pairs well with slow cooker pot roast? Here are some Mississippi pot roast sides that I recommend:
- Classic Mashed Potatoes soak up all the natural cooking juices the pot roast produces.
- Use slices of French bread to dip in the extra au jus you’ll have. It’s savory, briney, and has such great flavor so be sure to sop it up with something!
- Even rice would be an option and a fine pairing for your Crock Pot pot roast.
How to Store Mississippi Pot Roast
Extra slow cooker Mississippi pot roast will keep airtight in the fridge for up to 5 days and in the freezer for up to 4 months.
Tips for the Best Mississippi Pot Roast
I recommend that you sear the roast in a skillet before slow cooking it in order to keep it moister, juicier, and more tender. Although, technically you could get away without searing the chuck roast if you’re rushed.
When you place the chuck roast in your slow cooker, as a reminder, you do not need to add any additional liquid. The roast has a way of making more as it cooks.
I suggest an 8-quart slow cooker or similar size when making Mississippi pot roast in your slow cooker. I wouldn’t go too much smaller though because you need sufficient room to fit the large chuck roast.
I like to use whole pepperonconis for their presentation, although slices or rings are fine.
If your Mississippi pot roast is tough when you think it should be done, it needs to cook more. You should be able to pierce it with a fork, the meat should twist off easily in the fork, and it should be very tender. If it’s not, allow it to cook more.
For a slow-ish cooking slow cooker (some of them really do live up to their slow name) and a large piece of meat, this could mean onwards of 12 hours.
