There’s nothing better on a busy workday than knowing you can reach into your freezer, grab the rump roast you bought on sale at the grocery store and froze in order to keep it until “I don’t know when,” and then slow cook it deliciously over the next eight to ten hours while you’re gone at work.

Your house will smell amazing, and you’ll have spent all of ten minutes throwing dinner together, ready to eat when you walk in the door.

It’s like having your very own Alice from The Brady Bunch, except that you don’t!

This slow cooker pot roast starts with a FROZEN rump roast.


  • 1 3-pound rump roast, frozen
  • 4 medium potatoes, peeled and cubed
  • 2 large carrots, peeled and cut into chunks
  • 2 medium onions, diced
  • 2 garlic cloves, minced
  • 1 tablespoon garlic salt
  • 1/2 teaspoon black pepper
  • 1 tablespoon dried parsley
  • 1 can beef broth


  1. Place the potatoes, carrots, onions and garlic into the bottom of a slow cooker.
  2. Set the frozen roast on top, fat side up. Pour the beef broth over the roast. Sprinkle the garlic salt, pepper and parsley over the roast and veggies.
  3. Cover and set to cook for 8 to 10 hours on low.


The roast will be SUPER tender once it's done cooking, so be careful as you're removing it from the slow cooker to serve as it's likely to fall apart. (This is a good thing!)
