Chef’s Pro Tips for Perfect Results

Choose the right beef: Flank steak or sirloin both become incredibly tender in the slow cooker.
Slice against the grain: This keeps the beef juicy and easy to chew.
Don’t overcook the peppers: Add them later for that perfect tender-crisp bite.
Thicken the sauce: A cornstarch slurry during the last 30 minutes will make it luxuriously silky.

Texture & Flavor Secrets

The beauty of this recipe lies in its contrasts—melt-in-your-mouth beef against crisp-tender peppers, all coated in a glossy, savory-sweet sauce.
