- 1 tsp garlic powder
- 1 tsp onion powder
- 1 tsp smoked paprika
Garlic Butter Sauce
- 5 tbsp unsalted butter
- 6 garlic cloves, minced
- 2 cups beef broth
- 2 tbsp Worcestershire sauce
- 1 tbsp soy sauce
- 1 tbsp Dijon mustard
- 1 tsp dried thyme
- ½ tsp dried rosemary
- ½ tsp black pepper
- ¼ tsp crushed red pepper flakes, optional
For Thickening
- 2 tbsp cornstarch
- 2 tbsp cold water
Garnish
- 2 tbsp fresh parsley, chopped
- Fresh thyme, optional
- Freshly cracked black pepper
Step-by-Step Instructions
1. Season the Beef
Pat the chuck roast thoroughly dry with paper towels.
Season all sides with salt, black pepper, garlic powder, onion powder, and smoked paprika.
Let the roast rest for about 10 minutes while heating the skillet.
2. Sear the Roast
Heat olive oil in a large skillet over medium-high heat.
Add the roast and sear for 3–4 minutes per side, until a deep golden-brown crust forms.
Transfer the browned beef to the slow cooker.
3. Prepare the Garlic Butter
Reduce the skillet heat to medium.
Add butter and minced garlic.
Cook for about 30 seconds, stirring constantly, until fragrant.
Pour in the beef broth and scrape up the flavorful browned bits from the skillet.
4. Add the Seasonings
Stir Worcestershire sauce, soy sauce, Dijon mustard, thyme, rosemary, black pepper, and red pepper flakes into the broth.
Simmer for about 1–2 minutes.
Pour the entire mixture over the beef in the slow cooker.
5. Slow Cook
Cover and cook on LOW for 8–9 hours or HIGH for 4–5 hours.
For the most tender texture, cooking on LOW is recommended.
The beef is ready when a fork slides into it easily and the meat begins to pull apart.
6. Thicken the Sauce
Carefully transfer the cooked beef to a cutting board or serving platter.
Whisk together the cornstarch and cold water until smooth.
Stir the slurry into the slow-cooker juices.
Cover and cook on HIGH for another 10–15 minutes, until the sauce becomes slightly thick and glossy.
7. Slice and Serve
Allow the beef to rest for about 10 minutes.
Slice against the grain into thick pieces or pull it apart into large tender chunks.
Return the beef to the slow cooker or arrange it on a platter.
Spoon plenty of hot garlic butter sauce over the top.
Finish with fresh parsley, thyme, and cracked black pepper.
Cooking Tips
- Chuck roast is ideal because its marbling becomes wonderfully tender during slow cooking.
- Searing the meat first adds deeper flavor and a more appetizing exterior.
- Cook on LOW whenever possible for especially tender beef.
- Avoid repeatedly opening the slow-cooker lid because heat escapes quickly.
- If the roast still feels tough, it usually needs additional cooking time.
Serving Suggestions
Serve this slow cooker garlic butter beef roast with:
- Creamy mashed potatoes
- Garlic roasted baby potatoes
- Buttered egg noodles
- Steamed green beans
- Roasted carrots
Storage
Store leftover beef with some of its sauce in an airtight container in the refrigerator for up to 4 days.
Reheat gently in a covered skillet, saucepan, or 325°F (165°C) oven. Add a splash of beef broth if needed to keep the meat moist.
Leftover Ideas
- Shred the beef and serve it over mashed potatoes with extra sauce.
- Make toasted beef sandwiches with provolone or mozzarella.
- Toss leftover beef with egg noodles for a quick dinner.
- Use shredded beef in tacos, quesadillas, or rice bowls.
FAQs
Can I add potatoes and carrots to the slow cooker?
Yes. Add large potato chunks and carrots around the roast before cooking.
Can I use brisket instead of chuck roast?
Yes. Brisket works well, although its texture will be slightly different.
Do I have to sear the beef first?
No, but searing adds considerably more flavor and color.
Why is my slow-cooker roast still tough?
It generally needs more time. Continue cooking until the connective tissue breaks down and the meat becomes fork-tender.
