Recipe Ingredients

Main Ingredient:

Meat- Take 2 lb of chuck roast, freeze the meat before cutting. Remove the extra fats of meat.

Other Ingredients:

We are using here beef stock/broth, vegetable or chicken broth will also work but I would suggest you use beef broth to get a great taste!

You can also use sour cream instead of butter but I personally like the taste of roast with butter. We are using here dried onion soup mix, you can easily buy it from any market or departmental store. In spices, you can add or less according to your taste.

Recipe FAQs

Can I use Frozen Meat?

Yes, you can use frozen meat for this Instant Pot Mississippi pot roast recipe. Please note you will need a few more minutes to brown it.

Fresh (not frozen) beef will most likely get a better sear and turn out even more flavorful. If you are using frozen meat, I recommend fully defrosting it in the refrigerator before cooking. Then, dry the roast with paper towels before seasoning to get that desired golden-brown crust.

How Long Can I Keep it in the Fridge?

You can keep the Instant Pot Mississippi Pot Roast in an airtight container for up to 3 days in the refrigerator. It’s so tasty though, I don’t see it lasting that long! We never have leftovers at my house.

How Long Can I Keep it in the Freezer?

Up to 3 months!

This recipe freezes beautifully, making it a perfect make-ahead meal. Try freezing it in individual-sized containers for meal prep.

So What are the secret Ingredients!?

The first secret ingredient is a package of dry onion soup mix! Dry onion soup mix adds a TON of flavor that is perfect for seasoning beef. It’s usually a combination of dehydrated minced onion, beef broth flavor, and a mixture of spices that were made for complimenting beef.

The second secret ingredient is… jarred peppercini! These flavorful pickled peppers add just a hint of spiciness. Plus, using some of the peppercini’s liquid adds a bright burst of acidity to balance out the dish. It’s brilliant, really.

    Mississippi Pot Roast sounds awesome! I have leftover peppers from my garden. Dragon Roll, Cayenne and Jalapeño . Which would you recommend for this recipe? I'm not familiar with the peppers you use in your recipe. Many thanks, Susan.
