Recipe FAQs

How do I ensure the beef is tender?

Slow cooking on low heat for 8 hours breaks down connective tissue, resulting in tender, flavorful beef.

Remove some cooking liquid, whisk in cornstarch, then stir back and cook on high for 10 minutes to thicken.

What herbs complement the pot roast well?

Dried thyme, rosemary, and bay leaves add aromatic depth and pair well with beef and vegetables.

Directions

Step 01

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