  • 3 pounds of flank steak, cut into strips
  • 4 bell peppers, sliced (choose a combination of colors for variety)
  • 2 onions, sliced
  • 3 tablespoons of olive oil
  • 2 cloves of minced garlic
  • 1 1/2 cups of soy sauce
  • 1 1/2 cups of water
  • 1/2 cup of corn starch
  • 1 cup of brown sugar



Step 1: Prepare the Steak
Cut the flank steak into thin strips. If you find it difficult to slice, you can partially freeze the steak beforehand to make slicing easier.

Step 2: Sauté the Vegetables
In a skillet over medium heat, heat 1 tablespoon of olive oil.
Add the sliced onions and bell peppers, sautéing them until they are just tender. Then, transfer them to the slow cooker.

Step 3: Brown the Steak
In the same skillet, add another 2 tablespoons of olive oil and minced garlic.
Add the flank steak strips and sauté just until they start to brown. You do not need to cook them through, as they will continue cooking in the slow cooker. Transfer the steak to the slow cooker on top of the vegetables.


Step 4: Prepare the Sauce
In a bowl, combine the soy sauce, water, corn starch, and brown sugar. Stir until the corn starch and sugar are completely dissolved.
Pour this mixture over the steak and vegetables in the slow cooker.

Step 5: Slow Cook
Cover the slow cooker and cook on low for 6-7 hours or on high for 3-4 hours, until the steak is tender.

Step 6: Serve
Serve the pepper steak hot, ideally over a bed of rice or noodles.
