Why You’ll Love This Recipe
This recipe uses just a few convenient ingredients but delivers plenty of savory flavor. The combination of condensed cream of mushroom soup and beef consommé creates a rich base, while the onion soup mix adds a deep, savory onion flavor.
Chuck roast is particularly well suited to slow cooking because its connective tissue gradually breaks down during the long cooking process. The result is beef that becomes wonderfully tender and easy to shred.
Best of all, there is no complicated browning or elaborate preparation required.
Ingredients
- 3–4 lbs beef chuck roast
- 1 can (10.5 oz) condensed cream of mushroom soup
- 1 can (10.5 oz) beef consommé or beef broth
- 1 packet dry onion soup mix
How to Make Slow Cooker Creamy Onion Beef Chuck Roast
1. Add the Chuck Roast
Place the whole raw beef chuck roast directly into the center of the bottom of your slow cooker.
2. Season the Beef
Sprinkle the entire packet of dry onion soup mix evenly over the top of the chuck roast. Try to distribute the seasoning across the surface of the beef.
3. Make the Creamy Sauce
In a small bowl, whisk together the condensed cream of mushroom soup and the beef consommé or beef broth until the mixture is smooth and well combined.
4. Pour Over the Roast
Pour the creamy mushroom mixture evenly over the seasoned chuck roast. The sauce will slowly combine with the beef juices and onion seasoning as the roast cooks.
5. Slow Cook
Cover and cook on LOW for 8–10 hours or HIGH for 4–5 hours, until the beef is fork-tender and pulls apart easily.
For the best texture, avoid repeatedly lifting the lid during cooking.
6. Shred and Combine
When the roast is tender, shred the beef directly in the slow cooker using two forks. Gently mix the shredded beef into the rich onion gravy until everything is thoroughly coated.
Serve piping hot over mashed potatoes or alongside roasted vegetables.
Helpful Tips
Choose a well-marbled chuck roast when possible. The natural fat and connective tissue help create tender, flavorful beef during the long cooking process.
There is no need to add extra salt at the beginning because both the onion soup mix and beef consommé can already contain a significant amount of sodium. Taste the finished gravy before deciding whether additional seasoning is needed.
If the gravy is thinner than you prefer, allow the finished dish to rest uncovered for a few minutes after shredding. You can also remove some of the gravy and reduce it separately on the stovetop.
For food safety, beef should be cooked to a safe temperature, and the chuck roast should be tender enough to pull apart easily. A meat thermometer can be useful for checking the beef during cooking.
Serving Ideas
The creamy onion gravy makes this roast especially delicious with mashed potatoes. The potatoes absorb the savory sauce and create a classic comfort-food combination.
Other great side dishes include:
- Roasted carrots
- Green beans
- Steamed broccoli
- Roasted potatoes
- Egg noodles
- Buttered corn
- Crusty dinner rolls
For a complete meal, serve the shredded beef and gravy over mashed potatoes with roasted vegetables on the side.
Leftovers
Store leftover beef and gravy in an airtight container in the refrigerator and enjoy within a few days.
The leftovers reheat well and can be served over mashed potatoes, rice, or noodles. You can also use the shredded beef to make hearty sandwiches topped with some of the creamy onion gravy.
When reheating, warm the beef gently with some of the reserved gravy to help keep it moist.
