This slow cooker recipe for pot roast with onion soup mix is a great way to get tender roast beef on a weeknight after a long day.
This is my favorite way to prepare the ever popular Sunday dinner…pot roast. Slow cooking and onion soup mix creates a delicious fork-tender roast from an inexpensive cut of meat. Serve it up with a green salad and you have a great meal with little effort and almost zero minutes of prep.

INGREDIENTS FOR SLOW COOKER POT ROAST recipe:
- Dry Onion Soup Mix. The best thing is that you can use whatever packet of onion soup mix you prefer and you’ll still get a flavorful roast.
- Beef Roast. A chuck roast is an inexpensive cut of meat that becomes super tender and flavorful after hanging out in the CrockPot all day. Best of all, if you make a big one you will have yummy leftovers!
- Water. For extra flavor use beef broth instead of the 1/2 cup of water, if you have it.
- Cream of Mushroom soup. I like to make up a big batch of my Homemade Cream of Mushroom soup and use some for this recipe. But the red and white can works great!
- Carrots & red potatoes …optional. Use baby carrots to keep this easy and fast. Red potatoes are my favorite but my husband prefers golden potatoes. Both taste yummy if you feel like adding them.
How to make Slow Cooker Pot Roast:
- Heat oil in a hot skillet on medium-hight heat and place roast in when it is hot. Sear until the sides of the roast are nicely browned. Place the roast on a platter to wait.
- Mix cream of mushroom soup, water, and soup mix. Be sure to get the brown bits off the bottom of the pan…that adds great flavor.
- Pour mixture (only half!) into the bottom of the slow cooker.
- Place pot roast on top and pour the rest of the soup mixture on top of the roast.
- For 6 hours on the high setting or 8 hours on low heat.
- If desired, make a delicious gravy from the remaining broth.
Tips for Making Pot roast in the CrockPot:
For a bit of extra flavor try adding in:
- Worcestershire sauce. Just a bit goes a long way in adding depth of flavor. Try using about a tablespoon the first time.
- Garlic powder. I love adding a bit of garlic powder to the soup mixture to amp up the garlic flavor.
- Beef broth. Use part of a can of beef broth for the water for added flavor.
- Red wine. Or, a great substitute for the water is red wine. The alcohol helps break down the meat even better!
What order do the meat and veggies go into the CrockPot?
- Generally your root veggies like potatoes, onions, and carrots should go on the bottom of the slow cooker and the roast is put on top. This helps ensure your veggies don’t dry out and that they absorb the yummy flavor. However, sometimes they get mushy. If you don’t like that then place them on top of the roast and, half an hour or so before you serve, give them a bit of a stir to be sure they get coated in the liquid.
Do you have to brown a roast before putting it in the CrockPot?
- Yes, you really should brown your roast. It helps create flavor, speeds up the cooking time, and eliminates extra grease in your dish. It really is worth the extra five minutes it takes.
Should pot roast be covered with liquid in the slow cooker?
- It really doesn’t need to be. The little amount of liquid added will help to steam and moisten the roast. However, liquid is often used to help add flavor (imagine that roast being steamed with beef broth. Basically getting a beef broth infusion :)).
- To be sure your pot roast won’t dry out if it really is concerning you, use a turkey baster (or simply a spoon) to baste the cooking liquid on to the top of the pot roast about an hour before it’s done. Don’t be tempted to do this too often or you will slow the cooking time.
Do you need to stir food in a slow cooker?
- Nope. Nope. And nope. In fact, taking the lid off the slow cooker releases the heat and slows down the cooking process. Try to refrain from stirring until the end of the cooking time.
Got leftover Pot roast?
- Cut the leftover roast into smaller pieces and serve it over egg noodles for a beef stroganoff (sub the ground beef for the leftover beef).
- Roast beef sandwiches with mashed potatoes are always delicious!
- Make up a yummy shepherds pie (especially if you have leftover veg!)
- Vegetable Beef Soup is always perfect for using up leftovers.
