Ingredients

Instructions

  • Add the sliced steak strips to your slow cooker and sprinkle cornstarch over them, stirring to coat.
  • Add the sliced onions.
  • Whisk the garlic, ginger, soy sauce, sesame oil, broth or water, and black pepper.
  • Pour this mixture over the steak and onions in the Crockpot.
  • Cover and cook for 3 to 4 hours on high or 6 to 8 hours on low, or until the beef is tender.
  • Stir in the chilies (if using) and the green onions.
  • Serve hot, garnished with sesame seeds.

Notes

Slice against the grain: Slice your beef across the grain, not with it, for the most tender result.
Cook it low and slow: If you have time, cooking for longer over a low heat is best, as it makes the flavors meld perfectly and the meat extra-tender. If you're cooking it on high, check it often in case the sauce gets too thick or burns around the edges.
Onion doneness: If you prefer your yellow onion with a little "bite" add it halfway through the cooking time.
Toasted sesame seeds: I like to toast the sesame seeds in a dry skillet over a low-medium heat, shaking often, until fragrant and golden brown in places. This gives them a bolder flavor.
