Three ingredients. No searing. No stress.
One cheap chuck roast, two cans of cream of mushroom soup, two onions. That is the whole list, and it feeds a family of four for two nights.
The slow cooker does most of the work while you do everything else. Come back once after the first four hours to add the soup, and what comes out is fall-apart beef in a gravy thick enough for mashed potatoes, rice, or anything else that knows what to do with gravy.

Real Talk
For my family, this pot roast is the staple.
No matter how many other things I try to put on the table, this is the one that keeps winning.
At some point I stopped fighting that and just made peace with it. When a recipe gets requested like this, you keep it close.
It is also the cheapest thing on our regular rotation, and that matters more some weeks than others. Chuck roast, two cans of soup, a couple of onions, and the slow cooker turns it into the kind of dinner that makes a hard week feel a little softer.
Why This Recipe Works
- Three ingredients are enough. Chuck roast, onions, and cream of mushroom soup. That is all this version needs.
- No searing required. This is the easiest roast in the cluster and still delivers.
- Add the soup later. Let the roast release its juices first, then stir in the soup for a smoother, richer gravy.
- The leftovers are excellent. The flavor deepens overnight, and the gravy gets even better.
- One roast, multiple meals. A 5-pound chuck feeds a family of four for dinner with enough left for sandwiches, tacos, or a pan of pot roast lasagna the next night. Readers regularly tell me they get five or six meals out of one cook.
Ingredients for Crock Pot Pot Roast with Cream of Mushroom Soup
- 5 lb chuck roast (2.3 kg), tied if needed
- 2 teaspoon kosher salt + 1 teaspoon black pepper
- 2 yellow onions, thick-sliced (about 1 lb / 450 g)
- 21 oz cream of mushroom soup (two 10.5-oz cans)
How To Make Crock Pot Pot Roast with Cream of Mushroom Soup
Step 1: Season the roast
Pat the roast dry. Season all over with salt and pepper.
Step 2: Layer the ingredients
Place the seasoned chuck roast in the slow cooker. Top it with the thick-sliced yellow onions. Cook on HIGH for 4 hours.
Step 3: Check the roast
After the first 4 hours, the roast will have released its natural juices.
Step 4: Submerge the onions
Gently push the sliced onions down into the liquid. That beefy broth has been building since hour one.
Step 5: Add the cream of mushroom soup
Pour the soup over the roast.
Step 6: Finish cooking
Gently mix the soup into the beef juices to create the gravy. Cover and cook for 2 to 3 more hours on HIGH, until the roast is fall-apart tender.
The Payoff
Shred the beef and fold it back into the gravy. That is when the magic happens.
Expert Tips
- Wait to add the soup. Let the roast release its juices first, then stir in the soup for the best gravy.
- Sear if you want the extra depth. Totally optional, but a quick skillet sear before the slow cooker adds a layer you will notice.
- Low and slow is the move. If you have the time, cook on low for 8 to 10 hours. Still add the soup later.
- Store leftovers in the gravy. They stay moist and the flavor only gets better.
- Freeze in portions. Shred the beef, mix it with the gravy, and freeze it for easy meals later.
FAQs
Yes. Anything from about 2 ½ to 5 pounds works. A simple rule is 1 hour per pound, plus 1 extra hour.
Yes. Use a gluten-free cream of mushroom soup. That swap works just fine here.
Not this version. Creamy soups can separate under pressure. Use my Instant Pot Pot Roast instead if that is the method you want.
You can, but you will lose some sweetness and body in the gravy. If needed, add about ½ cup broth to make up the liquid.
Because the roast gets a better start without dairy from the beginning. Better flavor, better texture, better gravy.

The Leftover Math
A 5-pound chuck roast in this recipe gives you about 12 servings. For a family of four, that is dinner tonight plus at least one more meal in the fridge, sometimes two.
Here is what to do with what's left:
- Pot Roast Lasagna. Save 2 cups of shredded beef and as much gravy as you can. That is your sauce base. This move is not optional.
- Sliders or sandwiches. Pile the shredded beef on toasted rolls and spoon warm gravy over the top. Ten minutes, done.
- Rice bowls or tacos. Reheat the beef low and slow in the leftover gravy with a splash of broth. Serve over rice or pile into tortillas with whatever you have.
- Freezer portions. Shred the beef, mix it back into the gravy, and freeze in 2-cup portions. Reheat covered on low. It picks right back up.

Notes
Notes & Tips
- Wait to Add the Soup: Adding the cream of mushroom soup later in the cooking process ensures the roast develops color and doesn’t get boiled.
- Wiggle room is built in. Every roast is a little different, and so is every slow cooker. Just aim for fork-tender meat.
- Sear if you want. Totally optional, but a quick cast iron sear before slow cooking adds depth.
- Low and slow version: Cook on low for 8—10 hours total, adding the soup after 5—6 hours.
- Leftovers: Store in the fridge for up to 4 days. The flavor gets even better.
- Freezer-friendly: Shred the beef and freeze in portions with the gravy for easy meals later.
FAQs
Can I use a different size roast?Yes—this method works for most cuts between 2½ to 5 lbs. Just adjust the cooking time slightly. Can I use gluten-free cream of mushroom soup?
Yes. Any gluten-free cream of mushroom soup should work just fine. And I've swapped in Great Value's brand many times, and no one has ever noticed a difference. Can I make this in an Instant Pot?
Wouldn’t recommend it with this soup. But I’ve got a solid Instant Pot pot roast recipe that’s made for pressure cooking.

I made this recipe using venison roast, which can be dry because it is so lean. With this simply recipe, the roast was delicious and juicy. I've tried a lot of roast recipes for venison, and this is the best one. Plus, it is super easy. We'll be having this roast this weekend.

I'm really glad it worked so well for you! That's great info for other readers to know, so thanks for sharing!

I add a cup of wine instead of beef broth. I also use a tablespoon of A1. My daughters call me for the recipe
Dan
I came across a 2 3/4 pound chuck at the store and gave this a try, by cutting everything in half (except the cook time). Seasoned the roast, browned it, and followed on low just as the author recommends. Added 1 can of cream of mushroom soup after 5 hours and it was quite good.
Thanks.

Very Delicious and Easy. This recipe is a keeper, and if you haven't tried it, you should.

Great recipe
Laura
The first time I made this I used a 5 lb chuck roast, and we had 5 or 6 meals from this amazing pot roast. This second time I made this, I used a 2 lb chuck roast, and we invited some neighbors over to share it with us. We all had 2 servings, and there was even a little bit left over. Scrumptious!!!
Laura
I made this a few weeks ago, and it was absolutely delicious! We had so much leftover that we had 5 meals out of it since it's just my husband and myself. Thank you very much!
Laura
Thank you for this terrific and so easy recipe for a scrumptious meal (actually we had 5 meals from this pot roast for just my husband and me). I didn't have 2 Cream of Mushroom cans of soup, so I used what i had which was 1 Cream of Mushroom and 1 Cream of Chicken, and it was so very good. I'm not an experienced cook, and I love it when I read people talking about how they substituted something they had on hand for something called for in the recipe. This was one of those cases that worked beautifully. I will be making this many times in the future based on how much we enjoyed it. Thanks again!
Charina
Looks so delish! I would try it tonight. But when you said 8 hours on low. When do I put the cream of mushroom soup? After 8 hrs? And how much longer? Thank you.
Steve DeLawder
Made this a couple weeks ago, it was easy and it was
Awesome and making again today!!!
Tina chipman
Was looking for a roast dinner I could cook in my slow cooker. This one caught my eye, Thanks
Joanne
I added a pound of mushrooms, prefried, with the soup. It is absolutely delicious.
Cathleen
I tried making this recipe searing the roast first and on the second try did not sear. Huge difference - you must sear the roast first! Way more flavor!

Been using this for years! Always tender and full of flavor. Even the non mushroom people love it and don't even realize its mushroom soup and say it's their favorite potroast meal. I cook it over low heat for the full 8 hours. Sometimes I leave out the potatoes and make egg noodles then serve the meat and gravy over the noodles. The next day leftovers, if any, is even better as the gravy gets a little thicker and soaks in the meat the extra day.
