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.
Can I skip the onions?
You’ll lose sweetness and body in the gravy. If you must, add ½ cup beef broth to make up the liquid.
Why add the soup later?
Waiting keeps the roast from stewing in dairy, so you get better browning and a silkier finished gravy.
