Method
Slow-cook the beef
- Put the beef strips in a 6-quart slow cooker.
- Whisk together the broth, soy sauce, Worcestershire sauce, brown sugar, garlic, ginger, and black pepper, then pour the mixture over the beef and add the onion.
- Cover and cook on LOW for 5 to 6 hours or HIGH for 2 1/2 to 3 hours.
- Add the bell peppers, cover, and cook for 1 more hour on LOW or 45 minutes on HIGH, until the beef is fork-tender and the peppers are crisp-tender.
Thicken the sauce
- Whisk the cornstarch and cold water in a small bowl until smooth, then stir the mixture into the slow cooker.
- Cover and cook on HIGH for 15 to 20 minutes, until the sauce thickens.
Notes
For the most tender beef, cook on LOW until it is fork-tender. Refrigerate leftovers for up to 4 days or freeze them; use gluten-free tamari in place of soy sauce for a gluten-free option.
