🛒 Ingredients
- 1.5 to 2 lbs (approx. 700-900g) sirloin, flank, or round steak (sliced thin into bite-sized strips)
- 2 large bell peppers (one green, one red or yellow, sliced into strips)
- 1 large yellow onion, sliced
- 2 cloves garlic, finely minced
- ½ cup soy sauce (low sodium preferred)
- ¼ cup beef broth
- 2 tbsp brown sugar
- 1 tbsp olive oil or sesame oil
- 1 tsp fresh ginger, minced (or ½ tsp ground ginger)
- ¼ tsp black pepper
- 2 tbsp cornstarch mixed with 2 tbsp cold water (for the cornstarch slurry to thicken)
👩🍳 Step-by-Step Instructions
Step 1: Prep the Beef and Veggies
Slice your steak against the grain into thin, bite-sized strips. Chop your bell peppers and onion into thick slices so they hold up well during the slow cooking process.
Step 2: Layer into the Slow Cooker
Place the beef strips into the bottom of your Crock-Pot. Top the meat evenly with the sliced onions and bell peppers, and scatter the minced garlic right on top.
Step 3: Whisk the Glaze
In a medium bowl or measuring cup, whisk together the soy sauce, beef broth, brown sugar, olive oil (or sesame oil), ginger, and black pepper. Pour this savory sauce completely over the beef and vegetables in the slow cooker.
Step 4: Slow Cook to Tender Perfection
Cover the Crock-Pot with its lid. Cook on LOW for 5 to 6 hours or on HIGH for 3 to 4 hours. The beef should be incredibly tender when poked with a fork.
Step 5: Thicken the Sauce
About 20 minutes before serving, whisk your cornstarch and cold water together in a small bowl until smooth. Stir this slurry directly into the bubbling liquid in the slow cooker. Turn the Crock-Pot to HIGH (if it isn’t already) and let it cook uncovered for 15 to 20 minutes until the sauce transforms into a glossy, rich glaze.
Serve warm over a bed of fluffy white rice or noodles, and garnish with sesame seeds if desired!
💡 Quick Variations to Try
