FREQUENTLY ASKED QUESTIONS:
Can I use a different cut of beef?
Yes! While flank steak is traditional, you can use sirloin or chuck roast. Just make sure to cut against the grain for tenderness.
Why add vegetables later?
Adding peppers and onions in the last 1.5 hours keeps them tender-crisp instead of mushy. They’ll still absorb plenty of flavor!
Can I prep this the night before?
Absolutely! Prep the meat and vegetables the night before, store separately in the refrigerator, and combine in the morning.
TIPS FOR SUCCESS:
Don’t skip the cornstarch coating – it helps thicken the sauce
Cut meat against the grain for maximum tenderness
Use different colored peppers for visual appeal
Check meat at 5 hours – cooking time varies by slow cooker
Stir occasionally if possible
Let rest 10 minutes before serving
