Ingredients
1 boneless chuck roast, about 3 to 4 pounds
Chuck roast is the star of this recipe. This cut contains enough marbling and connective tissue to handle several hours of slow cooking. As it cooks, the connective tissue gradually breaks down, helping produce tender, juicy beef with plenty of flavor.
1 packet dry onion soup mix, about 1 ounce
The onion soup mix provides a concentrated combination of onion flavor and savory seasoning without requiring a long list of individual spices. It is the shortcut that gives this roast its classic, comforting taste.
1 can condensed cream of mushroom soup, 10.5 ounces
Cream of mushroom soup forms the foundation of the rich, creamy gravy. Spread over the roast before cooking, it melts into the juices and onion seasoning as the beef cooks.
How to Make Slow Cooker 3-Ingredient Chuck Roast
Step 1: Add the Roast
Place the boneless chuck roast in the bottom of your slow cooker.
There is no need to cut the roast into pieces. Keeping it whole helps retain moisture during the long cooking process.
Step 2: Add the Soup and Seasoning
Spread the condensed cream of mushroom soup evenly over the top of the chuck roast.
Sprinkle the dry onion soup mix evenly over the soup.
Don’t worry if the mixture looks thick at this point. As the roast cooks, its natural juices combine with the soup and seasoning to create a flavorful gravy.
Step 3: Slow Cook
Cover the slow cooker and cook:
– LOW: 8 to 9 hours
– HIGH: 5 to 6 hours
The roast is ready when the beef is very tender and easily pulls apart with a fork.
For the most tender result, the low setting is an excellent choice when your schedule allows.
Step 4: Shred and Serve
Carefully remove the roast and shred or slice the beef.
Return the meat to the slow cooker and gently stir it into the gravy. Spoon generous portions onto plates and serve hot.
Pro Tips for the Best Slow Cooker Chuck Roast
Brown the roast first for extra flavor
Browning isn’t necessary for this easy recipe, but if you have a few extra minutes, sear the chuck roast in a hot skillet before transferring it to the slow cooker. The browned exterior can add another layer of roasty, savory flavor.
Don’t keep opening the lid
Try to leave the slow cooker covered throughout cooking. Each time the lid is removed, heat escapes and the cooking process can take longer.
Choose LOW when possible
For especially tender, pull-apart beef, cooking the roast on LOW for 8 to 9 hours gives it plenty of time to soften.
Let the gravy do the work
Once the beef is shredded, gently mix it with the gravy before serving. This coats every piece with the creamy onion flavor.
Keep leftovers with the gravy
Store leftover beef together with the gravy rather than separately. The sauce helps keep the meat moist and flavorful when reheated.
Easy Variations
Extra-Gravy Chuck Roast
If your family cannot get enough gravy, add a second can of condensed cream of mushroom soup. This gives you extra sauce for mashed potatoes, noodles, or rice.
Mushroom-Lover’s Version
Add sliced mushrooms during the final portion of cooking for additional mushroom flavor and texture.
Vegetable Dinner
Add hearty vegetables such as carrots or potatoes if you want to turn the roast into more of a one-pot meal. Cut vegetables into similarly sized pieces so they cook evenly.
Leftover Roast Sandwiches
Pile leftover shredded beef onto toasted rolls and spoon some of the warm gravy over the top for an easy next-day roast beef sandwich.
What to Serve With Chuck Roast
The rich gravy makes this roast especially delicious with something that can soak it all up.
Mashed Potatoes
Creamy mashed potatoes are perhaps the classic pairing. Spoon the beef and plenty of gravy directly over the potatoes.
Buttered Egg Noodles
Tender egg noodles provide an easy base for the shredded beef and creamy onion gravy.
Fluffy Rice
Rice is another simple option that absorbs the savory sauce beautifully.
Green Beans
Fresh or steamed green beans provide a lighter, crisp contrast to the rich roast.
Roasted Carrots
Sweet roasted carrots pair naturally with the deeply savory beef and gravy.
Dinner Rolls
Keep a basket of warm rolls nearby for anyone who wants to mop up every last drop of gravy.
How to Store Leftovers
Allow leftover roast to cool before transferring it to an airtight container. Keep the beef and gravy together and refrigerate.
For the best quality, enjoy leftovers within 3 to 4 days.
Reheat gently on the stovetop or in the microwave, adding a small splash of water or broth if the gravy has thickened considerably.
The shredded beef can also be frozen with its gravy for a convenient future meal.
