Slow Cooker Roast Beef

Slow Cooker Roast Beef uses a 5-pound chuck roast seasoned simply with salt, pepper, and garlic, seared in vegetable oil before slow cooking. The method focuses on reaching the right internal temperature for medium rare or medium doneness. This approach produces tender, flavorful beef with a straightforward slow cooker technique suitable for a weeknight meal.

  1. Rub the chuck roast with the salt, pepper and garlic.
  2. Heat up your slow cooker insert (if cast aluminum) or a large pot on high heat with the vegetable oil.
  3. Sear the beef on each side for 3-4 minutes.
  4. Put the beef and the drippings from the pan into your slow cooker.
  5. Cook on low for 90 minutes.
  6. Using a standard meat thermometer or a slow cooker with a thermometer probe, cook to 135 (medium rare) or 140 (medium) degrees.

Notes

  • Because slow cooker temperatures and roast sizes vary, use a meat thermometer to ensure your chuck roast reaches your desired doneness.
  • The recommended 90 minutes on low was tested for a 5-pound chuck roast and suits a weeknight meal timing.
