FAQs
Can I use a different cut of beef?
Yes, chuck roast or round roast works best because they become tender and shred easily after slow cooking. Avoid lean cuts that may dry out.
Is it necessary to strain the onions from the broth?
Straining the onions helps create a smooth gravy, but you can leave them in if you prefer a chunkier sauce with added texture.
