“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.

The 1 carbohydrate for this recipe does not include the bread and potatoes if you are counting carbs! 🙂
i have a similar recipe for the slow cooker but was wondering if this could be in the instant pot instead and add the gravy packets in with the roast up front? the recipe i have you cook it in with the gravy packets
It’s hard to say without trying. I apologize.
Love this recipe. Growing up in a poor family with only a working mother, there was always a frozen meat/gravy entree we heated up and ate over white bread. They were cheap but filling and budget friendly.
How well this roast freeze after being made ? Do you put gravy on or do you want till your going to serve it ?
Do you have to shred the roast? If it’s tender can you just slice it down for sandwiches or serve with mashed potatoes and gravy and a vegetable like pot roast.
it will shred when you slice it, unless you cook for less time. I usually do 7 hours on low if I want to slice a roast.
You are right. Roast beef juice can be defatted and gravy from the beef alone can be made.
Why do you put those nasty tasting gravy packets in your cooking? Your beef roasts will make its own wonderful flavored gravy! Just saying …
So where is your recipe Sherli?
I make a bottom round beef roast, with a seasoning packet. Cooks for about 6 hours in crock pot. That’s dinner for one evening. The leftover beef, I slice and stew in gravy for hot roast beef sandwiches. My kids and husband love both meals
Toasting and buttering rolls before serving, adds a great touch for sandwiches
Does it matter if you use a frozen roast for this recipe? Or should I thaw out my roast first
I always take my roast from freezer to crockpot!!! I add a bottle of summer shandy beer…& 7-8 hrs later I have an incredible tasty & tender roast beef—sandwiches or as a meal with roasted veggies (or in the pot with the meat—potatoes, carrots & onions!!!!!
