- 6 cloves garlic, minced
- 2 cups beef broth
- 2 tbsp Worcestershire sauce
- 1 tbsp soy sauce

For the Vegetables (Optional)

Step-by-Step Instructions
1. Prepare the Beef Roast
Pat the beef roast dry with paper towels.
Season all sides generously with salt, black pepper, garlic powder, onion powder, and smoked paprika.
Allow the roast to sit for 15–20 minutes so the seasoning can absorb.
2. Sear the Roast
Heat olive oil in a large skillet over medium-high heat.
Sear the beef on all sides until deeply browned, about 3–4 minutes per side.
Transfer the roast to the slow cooker.
3. Prepare the Garlic Butter Sauce
Melt butter in the same skillet.
Add minced garlic and cook for 30 seconds until fragrant.
Stir in beef broth, Worcestershire sauce, soy sauce, thyme, and rosemary.
Scrape up any browned bits from the pan for extra flavor.
4. Assemble the Slow Cooker
Place carrots, potatoes, and onions around the roast if using.
Pour the garlic butter sauce over the beef.
Add the bay leaf and cover with the slow cooker lid.
5. Slow Cook Until Tender
Cook on LOW for 8–9 hours or HIGH for 4–5 hours until the beef easily pulls apart with a fork.
Remove the bay leaf before serving.
6. Serve the Roast
Slice or shred the tender beef.
Spoon the garlic butter sauce over the top.
Garnish with fresh parsley and serve warm.

Can I use another cut of beef?
Yes. Brisket, rump roast, or bottom round can also work, but chuck roast gives the most tender texture.

Yes, but searing adds a richer color and deeper flavor to the final dish.
Can I prepare this ahead of time?
Absolutely. Cook the roast, store it with the sauce, and reheat when ready to serve.
How do I thicken the sauce into gravy?
Mix a little cornstarch with cold water and stir it into the hot sauce until thickened.
