Equipment

  • Crockpot This is my all-in-one Instapot + Slow Cooker + Pressure Cooker

Ingredients

  • 2 lbs Sirloin Steak cut into strips
  • 1 tsp Garlic Powder
  • 1 tsp Ground Ginger
  • 1½ tsp Salt
  • 2 tbsp Minced Garlic
  • 3 tbsp Soy Sauce
  • ½  tsp Worcestershire Sauce
  • 1 tbsp Brown Sugar
  • 3 tbsp Cornstarch
  • ½  cup Chicken Broth you can also use beef broth
  • 2 tbsp Light Olive Oil
  • 1 14.5 oz Fire-Roasted Tomatoes
  • 1 Medium Onion sliced
  • 2 Bell Peppers

Instructions

  • Brown the Steak - Heat a large skillet over medium heat. Add olive oil, then add the beef strips. Season beef with garlic powder, ground ginger, and salt. Sauté until the steak is browned on all sides. Transfer the beef to the slow cooker. This only takes like 5 minutes
  • Make the Savory Sauce - Using the same skillet, reduce to medium-low heat. Add minced garlic and sauté until fragrant, about 30 seconds. Stir in soy sauce, sesame oil, Worcestershire sauce, brown sugar, cornstarch, and chicken broth. Whisk until smooth and slightly thickened.
  • Slow Cook - Pour the sauce over the beef in the crockpot. Add the fire-roasted tomatoes and stir. Cover and cook on High for 3 to 4 hours, or on Low for 6 to 8 hours.
  • Add Vegetables - In the last 1.5 hours of cooking, add sliced onions and green bell peppers. Stir gently, cover, and continue cooking on LOW for 1 additional hour, until the beef is tender and the vegetables are softened. You don't want to cook the veggies for the entire duration. If you do, they will end up mushy.
