Best Slow Cooker Pot Roast Recipe

I can remember dinners after church at my “granny’s house.” We would walk inside and the whole house would be filled with this delightful smell of her delicious pot roast slow cooking in the oven.

Now days, I don’t cook pot roast in the oven, I use this slow cooker. I put the beef cut in it frozen, peel and add fresh root vegetables, spices and broth, cover it with a lid, and forget it until supper time.

The house smells delicious and it always makes me think of my sweet “Granny Dixon.”

What Is The Best Roast Cut for Making Pot Roast

Popular beef cuts for roasts do vary a bit and each cut has their own level of tenderness. Roast are tough cuts beef or pork, which makes them perfect for slowing cooking. If under-cooked, they will be tough and chewy.

  • Chuck Roast – tender fall apart flavor that can be easily shredded
  • Shoulder Roast – great marbling making it cook up tender and juicy
  • Rump Roast – boneless cut full of flavor – varying levels of tenderness due to cut
  • Round Roast – (top or bottom) super lean cut that is perfect for slicing

There are several others, but these are the most common. Our favorite roast for slow cooking is the Chuck Roast since it cooks up and just falls apart with juices and flavor. It’s also great for left-overs too.

TIP: If you are wanting a juicy, fall apart pot roast – then fat is your friend. The fat content makes it cook up more tender and much juicier. So use this as a guide when shopping for cuts. If you wish to slice into roast beef for sandwiches, choose a more lean cut roast.

Best Vegetables To Add To Pot Roast

Vegetables that can be added are limitless, especially if you grow a garden. This is what makes slow cooker pot roast the perfect one-dish meal. All your veggies and meat are all cooked together and the juices blend to be delicious.

The most common vegetables added are fresh peeled potatoes, onions and carrots. And then you may toss in some fresh rosemary or even basil for additional flavor. Of course, at our house, don’t forget the garlic powder either.

How to Cook Slow Cooker Pot Roast


Turn slow cooker on high and place frozen pot roast inside, no need to thaw. Sprinkle cut roast with salt, pepper, and garlic powder to taste. Cover with lid.

Wash, peel and chunk vegetables. We use fresh potatoes, carrots and onions. You can add an onion soup mix or even a mushroom soup if you like. We love the flavor of this beef broth and just the delicious juices from the fresh vegetables and roast.

Place root vegetables on top of and around roast in slow cooker. Sprinkle with a generous helping of salt, pepper, garlic powder and whatever other spices your family loves.

At times, I add dried rosemary and even some basil, it really depends on the mood.

TIP: Adding beef broth is not necessary, but it does add additional flavor. Since my family likes to eat pot roast and potatoes in a bowl like a hot soup, the broth is welcome. They enjoy the extra beef juices.


Place lid on slow cooker and cook on high for 6 hours. Check meat to see if tender and fall- apart-juicy. Our roasts are cut into 2 lbs, at the butcher, and this is normally just enough time. Yours can vary based on the size of cut.

Serve with a side dish of garlic sauteed green beans and fried okra and dinner is ready without all the fuss.

    1. Hi Darlyn,

      Great question. I suggest the same recipe, frozen or not. You’ll want to put the lid on, cook on high and after 4 hours,since thawed, I’d suggest to stick a fork in it and test it for “fall apart” tender. It will be soft, but you want to cook it until you can easily tear it apart with a single fork. If it’s not, continue to cook and check every hour. Slow cooker brands all cook at different temperatures so it can vary a little. Hope this helps.
