Meat
- 3 to 3 1/2 pounds beef chuck roast
Soup Mix
- 2 (1-ounce) packets dry onion soup mix
Vegetables
- 2 large yellow onions, thinly sliced
Liquids
- 2 cups beef broth (low-sodium preferred)
- Prepare the onions: Peel and thinly slice the yellow onions into half-moons. Scatter them evenly over the bottom of a 6-quart slow cooker to create a flavorful onion bed for the roast.
- Prepare the roast: Pat the beef chuck roast dry with paper towels to remove excess moisture, which helps achieve slight browning during cooking. Place the roast directly on top of the sliced onions in the slow cooker.
- Season the roast: Sprinkle the dry onion soup mix evenly over the top and sides of the roast. Use your hands to gently pat the mix onto the meat so it adheres and seasons the beef thoroughly.
- Add the broth: Pour the beef broth around the sides of the roast carefully, avoiding washing off the onion soup mix from the top of the meat. This will help form a rich base for the gravy.
- Cook low and slow: Cover the slow cooker with the lid and cook on LOW for 8 to 10 hours, until the roast is very tender and pulls apart easily with a fork.
- Shred the beef: Once cooked, use two forks to gently shred the roast into large chunks right in the slow cooker, leaving some pieces intact for a classic pot roast texture. Stir the onions and cooking juices to coat all the beef in gravy.
- Adjust gravy consistency (optional): Taste the gravy and add salt only if needed. For a thicker gravy, remove 1 cup of hot cooking liquid, whisk in 1 to 2 teaspoons cornstarch until smooth, then stir it back into the slow cooker and cook on HIGH for 10 to 15 minutes until thickened.
- Serve: Spoon the pot roast with plenty of caramelized onions and glossy gravy over each portion. Store leftovers in an airtight container in the refrigerator for up to 3 days; flavors will deepen overnight.
Notes
- Using low-sodium beef broth helps control the overall saltiness, as the onion soup mix is naturally salty.
- Patting the roast dry before cooking encourages slight browning and richer flavor.
- Cooking on LOW for 8 to 10 hours is essential for tender, pull-apart beef.
- Thickening the gravy with cornstarch is optional but enhances the texture for serving.
- Leftovers taste even better the next day due to flavor melding.
- This recipe requires minimal prep and uses only four main ingredients, making it perfect for busy cooks.
