| Ingredient | Amount |
| Unsalted butter | 4 tablespoons |
| Garlic cloves, minced | 6 |
| Beef broth | 1 cup |
Seasonings
| Ingredient | Amount |
| Salt | 1½ teaspoons |
| Black pepper | 1 teaspoon |

Step-by-Step Instructions
Season the beef roast evenly with salt, pepper, paprika, garlic powder, onion powder, thyme, and rosemary.
Heat olive oil in a large skillet over medium-high heat. Sear the roast for 3–4 minutes on each side until a deep golden crust forms.
Transfer the roast to the slow cooker.
Mix the butter, minced garlic, and beef broth together. Pour the mixture over the roast.
Cover with the lid.
Cook on LOW for 8 hours or HIGH for 5 hours, until the beef reaches an internal temperature of at least 195–205°F (90–96°C) for fall-apart tenderness.
Allow the roast to rest for 10 minutes before slicing against the grain.
Spoon the garlic butter juices over the beef before serving.
Best Tips
Choosing a well-marbled chuck roast will give the most tender and flavorful results after slow cooking.
Always sear the meat before placing it in the slow cooker. This simple step adds incredible depth of flavor.
Avoid lifting the slow cooker lid while cooking because each opening releases heat and extends the cooking time.
Let the roast rest before slicing so the juices stay inside the meat.

What to Serve With

Make-Ahead Instructions
Season and sear the beef one day ahead. Refrigerate it overnight, then place everything into the slow cooker the next morning before cooking.
Storage
Store cooled leftovers in an airtight container in the refrigerator for up to 4 days.
Reheating
Reheat slices gently in a covered skillet with a splash of beef broth over medium-low heat, or microwave in 30-second intervals until warmed through.
Freezing
Freeze sliced beef with some of the cooking juices in freezer-safe containers for up to 3 months. Thaw overnight in the refrigerator before reheating.
Common Mistakes to Avoid
Using a lean cut of beef can result in dry meat because it lacks the connective tissue needed for slow cooking.
Skipping the searing step reduces the overall flavor and color of the finished roast.
Overcooking on the high setting for too long may dry out the beef despite using a slow cooker.
Cutting the meat immediately after cooking allows the juices to escape, making the roast less tender.
