Yes! Cook on LOW for 8 hours or until fork-tender.

Do I need to sear the roast first?
Not required, but it boosts flavor and browning if you have time.

Can I make this ahead of time?
Yes — it tastes even better the next day after the flavors develop.

What other cuts of beef can I use?
Bottom round or rump roast works, but chuck roast gives the best tenderness.
