Add the beef to the crockpot, then pour in the orange sauce, soy sauce, brown sugar, garlic, and ginger. Stir gently to coat everything evenly.
Cook on LOW for 6 hours or HIGH for 4 hours, until the beef is fork-tender.
Once cooked, use a fork to lightly shred a few pieces of beef directly in the pot, leaving the rest chunky. This naturally thickens the sauce and gives it that sticky, glossy texture without extra steps.
If you want an even deeper glaze, crack the lid slightly and cook on HIGH for 10–15 more minutes, letting the sauce tighten up just a bit.
Spoon the citrus-glazed beef over warm rice and finish with steamed broccoli for balance.
