Ask About This Recipe

How do I ensure the beef stays tender?

Searing the beef before slow cooking locks in juices, and cooking it on low for several hours breaks down connective tissues, resulting in tender meat.

Can I substitute the Yukon Gold potatoes?

Yes, Russet potatoes also yield creamy mashed potatoes, though Yukon Golds provide a richer, buttery texture.

How to thicken the gravy from cooking liquid?

Remove some cooking liquid, whisk in cornstarch, then stir back into the cooker and cook on high until thickened.

What herbs complement this slow-cooked dish?

Thyme and rosemary are used to enhance the broth's flavor, adding herbal depth to the meat and vegetables.

Is it necessary to remove bay leaves before serving?

Yes, bay leaves should be discarded after cooking as they are tough and not pleasant to eat.

How To Make It

Step 01

Season the Roast: Pat the beef chuck roast dry and season all sides evenly with kosher salt and black pepper.
