Slow Cooker Beef Chuck Roast
This Slow Cooker Beef Chuck Roast is the kind of warming, comforting dinner that practically cooks itself. A tender beef chuck roast is placed in the slow cooker and covered with a rich, savory onion-garlic mixture. After several hours of slow cooking, the beef becomes incredibly tender and flavorful, with a delicious gravy that’s perfect over mashed potatoes.
Ingredients
For the Beef
- 3–4 lbs (1.4–1.8 kg) beef chuck roast
- 1½ teaspoons salt
- 1 teaspoon black pepper
- 1 teaspoon paprika
- 1 tablespoon olive oil
- 1 large onion, sliced
- 4 cloves garlic, minced
- 3–4 carrots, cut into chunks
- 1½ lbs potatoes, cut into large chunks
For the Slow Cooker Mixture
- 1½ cups beef broth
- 1 packet onion soup mix
- 2 tablespoons Worcestershire sauce
- 2 tablespoons tomato paste
- 1 tablespoon Dijon mustard
- 1 teaspoon dried thyme
- 1 teaspoon dried rosemary
- ½ teaspoon garlic powder
- ½ teaspoon black pepper
Directions
1. Season the Beef
Pat the beef chuck roast dry with paper towels.
Season all sides generously with salt, black pepper, and paprika.
2. Sear the Roast
Heat olive oil in a large skillet over medium-high heat.
Sear the beef for approximately 3–4 minutes per side, until deeply browned.
This step is optional, but it adds a wonderful roasted flavor to the finished dish.
3. Prepare the Slow Cooker
Place the sliced onions, carrots, and potatoes in the bottom of the slow cooker.
Set the seared beef chuck roast on top of the vegetables.
4. Make the Mixture
In a bowl, whisk together the beef broth, onion soup mix, Worcestershire sauce, tomato paste, Dijon mustard, thyme, rosemary, garlic powder, and black pepper.
Mix until smooth and well combined.
5. Pour Over the Beef
Pour the mixture evenly over the raw or seared beef chuck roast.
Add the minced garlic around the roast.
Make sure the vegetables are distributed around the meat.
6. Slow Cook
Cover with the lid.
Cook on:
LOW: 8–9 hours
HIGH: 4–5 hours
For the most tender beef, cooking on LOW is recommended.
The roast should be fork-tender and easy to pull apart when finished.
7. Make the Gravy
Once the beef is cooked, carefully transfer it to a serving platter.
For thicker gravy, mix:
- 2 tablespoons cornstarch
- 3 tablespoons cold water
Stir the slurry into the liquid in the slow cooker.
Cover and cook on HIGH for approximately 10–15 minutes, until thickened.
8. Serve
Slice or shred the tender beef.
Arrange the potatoes and carrots around it.
Spoon the rich gravy over the beef and vegetables.
Garnish with fresh parsley if desired.
Tips for the Best Slow Cooker Beef
Use chuck roast: Its marbling and connective tissue make it ideal for long, slow cooking.
Don’t skip the searing if you have time: Browning creates deeper flavor.
Keep the lid closed: Every time you lift the lid, heat escapes and cooking time increases.
Don’t add excessive liquid: The meat and vegetables release additional moisture as they cook.
Cook until tender, not simply until the clock says it’s done: Chuck roast becomes tender when its connective tissue has had enough time to break down.
Easy Variations
Creamy Beef Roast
Stir ½ cup heavy cream or sour cream into some of the finished gravy before serving.
Mushroom Beef Roast
Add 8 oz sliced mushrooms during the final 2–3 hours of cooking.
Garlic Herb Roast
Increase the garlic to 6 cloves and add extra rosemary and thyme.
Spicy Beef Roast
Add crushed red pepper flakes or a little hot sauce to the cooking mixture.
Beef and Onion Gravy
Skip the potatoes and carrots and add extra sliced onions. Serve the finished roast over mashed potatoes with plenty of gravy.

Storage
Allow leftovers to cool before transferring them to airtight containers.
Refrigerate for up to 3–4 days.
Reheat gently in a saucepan or microwave with some of the gravy to prevent the beef from drying out.
