- Sear the roast on all sides before adding it to the slow cooker for deeper flavor.
- Don’t add extra liquid. The recipe has enough—too much can make the sauce watery.
- Cook on low until fork-tender. If the beef is still tough, it just needs more time.
- To thicken the sauce: Simmer the cooking liquid on the stove for 5–10 minutes.
- To balance the sauce: Add a tiny pinch of sugar if it’s too acidic, or skim off excess fat if it tastes oily.
