“Delicious and a favorite for our family – especially my 4 year old son! We substitute venison and serve on buns for an easy dinner during the week.”

This is the type of comfort food you would see on the menu at a local diner. In fact, I would order these Hot Roast Beef Sandwiches at Marie Callender’s when I worked there years ago. Marie Callender’s would often run these as a lunch special. See my Chicken Version of this recipe here: Slow Cooker Chicken and Gravy, which is just like this but with chicken!
This meal is heaven on a plate. The bread is placed down (often Texas toast), then beef and gravy piled on, and always served with mashed potatoes. Other beef recipes we love to make are Slow Cooker French Onion Pot Roast or these No Peek Beef Tips.
Key Ingredients
This is a basic recipe that anyone can make, though it tastes just like a restaurant made it!
- Beef Roast: I use a bottom round beef roast for this recipe (also called a rump roast). It shreds up nice and has way less fat to pick out before serving as a chuck roast does.
- Seasonings: Salt and pepper, as well as onion powder, are the only seasonings you need.
- Brown Gravy Packets: These help create amazing homemade gravy and add additional flavor to the overall meal.
How to Make Hot Roast Beef Sandwiches
You can start this recipe in the morning and come home to a perfect meal. Here is how you do it:
- Lightly season the roast, whisk the gravy mix with water, and pour it over.
- Cook on LOW until fork-tender.
- Lift out the beef, defat the liquid, shred, and fold the meat back into the gravy.
Variations
I’ve been making this recipe for over 10 years! Here are my variations that work well.
- I do prefer a bottom-round roast for this recipe, but you can use a chuck roast or top-round.
- Onions and mushrooms are great additions, but beware, both may make the gravy thinner, and you’ll need to add a cornstarch slurry.
- You can double the recipe to easily make more gravy. For an extra kick in taste, use beef broth or beef stock instead of water.
My Serving Suggestions
This recipe can be served in many ways! Here are our favorites:
- Serve the hot roast beef and gravy over bread with a generous helping of mashed potatoes.
- Corn, green beans, French fries, or a fresh green salad make perfect side dishes.
- You can also use this recipe to top baked potatoes, egg noodles, or steamed white rice for an easy meal.
- For a classic sandwich, pile leftover roast beef between two slices of white bread—or any bread you like—for a quick and delicious hot beef sandwich..
Can Frozen Beef Be put in a Slow Cooker?
It’s best to thaw it out first, for some studies show it is not safe to cook frozen meat in the slow cooker, as the meat stays in the danger zone too long before it starts cooking.

Ingredients
- 3-4 lb. bottom round beef roast, chuck will work fine too
- salt
- pepper
- onion powder
- 1.74 oz. brown gravy mix packets, (two .87 oz. packets)
- 1 ½ cups water
Serving Suggestions
- white or sourdough bread
- mashed potatoes
Instructions
- Place the roast into a 4-quart or larger slow cooker.
- Sprinkle a small amount of salt, pepper and onion powder on to the beef.
- In a small bowl whisk together the gravy packets and water until smooth. Pour that mixture over the roast.
- Cover and cook on LOW for 8-10 hours.
- When the cooking time is done, remove the roast and place on to a plate, shred meat, discard any fat. Cover with foil to keep warm.
- De-grease the gravy in the slow cooker, I either do this by ladling off the grease with a spoon, or I take a paper towel and lay on top of the grease and pull off, the grease will come off on the paper towel, and the gravy will stay in the slow cooker.
- Serve the shredded beef and gravy over bread and with mashed potatoes.
- Enjoy!

How to Store and Reheat Leftover Roast
Add any remaining beef and gravy to an airtight container and store in the fridge for up to 4 days. When you’re ready to serve again, heat it over medium heat on the stove top until warmed throughout. Or you can microwave – but don’t over heat.

Is the roast supposed to be submerged in gravy?
A little at first, then more gravy will be created as it cooks.
I love this recipe. I forgot to buy the beef gravey packets. Can I substitute a jar of beef gravey and omit the water?
I think that would work great.
Can I cook this recipe on high for a quicker cook time?
Yes, I would do 5 hours on low.
Hubby and I love this recipe! Super easy, delicious & excellent for leftovers! Thank you for sharing!
Any suggestions on how to do this in a instant pot?
Thanks!
Can you use a rump roast?
Yes, rump roast will work well.
Made this for Christmas. Big hit with kids and grownups.
How big of a roast did you use .I have about 12 people to feed.
made today absoulutly love this receipe really good meal
This looks so good. I suppose I could do this stove top as well, correct?
It may be more tricky on the stove top. You could put it in a heavy pot with an oven safe lid and do it in the oven.
My Mom always made this either in the oven or on the stove stop. She preferred the oven, cooked faster and even. She would add water or beef broth, her words were “keep it short” which meant just enough liquid to go half way up the roast (don’t submerge). Keep an eye on the liquid to maintain that level throughout the cooking process. I would add the gravy packets to the liquid after cooking.
You could start off browning the meat on the stove, then take your roast out add onions with a little red wine.. mmm simmer and scrape the bottom before you add everything back in and shove her in the oven!
