How to Make Slow Cooker Chuck Roast
1. Add the Beef
Place the chuck roast in the bottom of your slow cooker. Arrange the pieces as evenly as possible so they cook consistently.
2. Add the Savory Seasonings
Sprinkle the dry onion soup mix evenly over the beef. Spread the condensed cream of mushroom soup over the top.

Cut the butter into several pieces and distribute them over the roast.
Cover and cook on LOW for 7–8 hours or HIGH for 4–5 hours, until the beef is extremely tender and easily pulls apart with a fork.
For the best texture, cooking the roast on LOW is recommended when you have the time.

Tips for the Best Slow Cooker Chuck Roast
Cook on LOW when possible: The longer cooking time allows the chuck roast’s connective tissue to break down gradually, producing exceptionally tender beef.
Don’t skip the gravy: Spoon plenty of the buttery sauce over the beef and your side dishes. It’s one of the best parts of the recipe.
Make the gravy smoother: For a more evenly distributed sauce, whisk the onion soup mix and cream of mushroom soup together before spreading the mixture over the roast.
Add mushrooms: For extra mushroom flavor, add about 8 ounces of sliced cremini or white mushrooms around the roast before cooking.
Add fresh herbs: Finish the roast with chopped fresh parsley or thyme for a fresh contrast to the rich gravy.
