  • Slow Cooker
  • sharp knife to cut onions
  • ginger grater


  • 2 lbs thin sliced sirloin beef often used for fajitas or carne picada
  • ¼ cup cornstarch
  • 2 medium onions sliced
  • 1 inch fresh ginger peeled and grated
  • 3-4 garlic cloves peeled and pressed
  • 1 cup brown sugar
  • 1 cup soy sauce
  • 1 cup water
  • 2 green onions sliced diagonally
  • sesame seeds for garnishing


  • Sprinkle the meat with the cornstarch and toss to coat and set aside.
  • In a separate bowl, whisk together soy sauce, water, brown sugar, ginger, and garlic.
  • Place the meat in the slow cooker, then follow with the onions on top, finally pour the sauce over the top.
  • Cover and cook on low for low for 6-8 hours, or on high for 4 hours
  • Serve over rice and garnish with green onions and sesame seeds


  • If you like a little kick, add some red pepper flakes.
  • I have made this recipe with all of the following cuts of meat and it works great: Sirloin steaks that I cut myself, stew meat, fajita meat (those two are already sliced) and flank steak, which you can again cut yourself or ask the butcher to do it for you. 
  • On the Trim Healthy Mama plan? Substitute the brown sugar with Swerve brown sugar,  or ½ cup of Truvia or 3-4 Tablespoons Super Sweet Blend, depending on your tastes. And, instead of using the cornstarch, you can use glucomannan. The conversion would be 4 teaspoons, but I think you could get away with 2-3. Just stir it into the sauce.
  • For a low carb or THM option, serve it over Spaghetti Squash instead of rice.
