Mississippi Pot Roast

Mississippi Pot Roast in the Slow Cooker is about the easiest dinner you can make your family. Making a Freezer Roast ahead of time makes busy weeknight suppers a breeze.

Any time I can find what I call a “dump dinner” I am so excited. To me, this means that all I do is “dump” the ingredients into a Crock Pot and walk away. It makes life so much easier! Along with this one, our Pizza Casserole, Dr. Pepper Ribs and Enchilada Soup fit the bill.

The great thing about this recipe is that you can make it right away or use it as a freezer meal. I like going ahead and getting this all ready when I get home with my groceries. That way I know that literally ALL I have to do is put the bag in the Crock Pot and turn it on. This is also great when I need someone else to get dinner going for me like one of the older kids or my husband.

Ingredients for a Slow Cooker Freezer Mississippi Pot Roast

Ingredients You’ll Need:

(full amounts in recipe box below)

  • Chuck Roast
  • Ranch Dressing mix
  • Au Jus mix
  • Butter
  • Peperoncinos

How Do You Make Mississippi Pot Roast?

First, put the meat in a Slow Cooker bag. These are my favorite things ever because you have almost zero clean up after (just the plates and utensils). When dinner is over, you just take the bag out and toss it in the garbage.

Then, sprinkle each of the seasoning packets over the roast. Add some butter and peppers and cook for eight hours.

If you’re saving it for later as a freezer recipe, close the liner tightly with a clip and freeze until you’re ready.

Do You Add Water to Mississippi Pot Roast?

Nope! Everything you need is already inside the bag.

What Do You Serve with Mississippi Pot Roast?

When we eat this as a sandwich (with some pepper jack or Swiss cheese on top) we like to serve it with french fries or chips. If not, we like mashed potatoes, corn on the cob, green beans and butter bread.

How Long To Cook Roast In Crock Pot

Well, it depends on how much meat you are cooking. For this recipe, we are using 3 pounds of roast which takes about 8 hours on low heat. If you have less time, you can crank up the heat to high and cook for 6 hours. I think meat is best when it is cooked the slowest way possible. Oprah has some really great charts for Crock Pot cooking times!

Mississippi Pot Roast in the Slow Cooker is tender and juicy. Make this freezer roast ahead of time for the easiest dinner you can make your family.

What kind of peppers are Pepperoncinis?

These are a mild and slightly sweet Italian pepper that usually comes in a jar. (There’s a photo above.)  If you’re looking for a heat comparison, they are right about the same spice level as a bell pepper.

This pot roast is tender and juicy and everyone in the family will be asking for it week after week. Enjoy!
