Method
 

  1. Slice steak thinly against the grain for tenderness. Season with salt and black pepper.
  2. Heat olive oil in a skillet over medium-high heat. Sear steak slices quickly on both sides. Transfer to crockpot.
  3. In the same skillet, sauté onions and bell peppers for 3–4 minutes. Add garlic and cook until fragrant. Transfer to crockpot.
  4. Whisk together beef broth, soy sauce, brown sugar, sesame oil, and ginger. Pour over beef and vegetables in the crockpot.
  5. Cover and cook on low for 6–8 hours or high for 3–4 hours, until beef is tender.
  6. In a small bowl, whisk cornstarch and cold water. Stir into crockpot and cook on high for 15–20 minutes, until sauce thickens.
  7. Serve hot over rice. Garnish with sesame seeds and sliced green onions.

Notes

For crispier bell peppers, add them during the last hour of cooking. You can substitute beef with chicken or pork, and serve with cauliflower rice for a low-carb version. Double the sauce if you like it extra saucy over rice.
