  • 1 tbsp Brown Sugar
  • 1 tsp Paprika
  • 1/2 tsp Black Pepper
  • 1/4 tsp Red Pepper Flakes optional
  • 2 tbsp Cornstarch
  • 2 tbsp Cold Water
  • Cooked Rice, for serving

Equipment

  • Crock Pot (Slow Cooker)

  • Medium bowl
  • Small bowl
  • Whisk
  • Measuring cups
  • Measuring spoons
  • Knife
  • Cutting board

Method
 

  1. Heat olive oil in a large skillet over medium-high heat.
  2. Sear the beef cubes in batches until browned on all sides. Do not overcrowd the pan.
  3. Place the sliced onions and bell peppers in the bottom of the crock pot.
  4. Arrange the seared beef cubes evenly over the vegetables.
  5. In a medium bowl, combine the diced tomatoes (undrained), beef broth, soy sauce, Worcestershire sauce, brown sugar, paprika, black pepper, and red pepper flakes (if using).
  6. Whisk well to combine the sauce.
  7. Pour the sauce evenly over the beef and vegetables in the crock pot.
  8. Cover the crock pot and cook on low for 6-8 hours, or on high for 3-4 hours, or until the beef is very tender.
  9. In a small bowl, whisk together the cornstarch and cold water until smooth.
  10. Stir the cornstarch slurry into the crock pot during the last 30 minutes of cooking to thicken the sauce.
  11. Serve the pepper steak over cooked rice.
  12. Garnish with fresh parsley or green onions, if desired.

Notes

For a richer flavor, use a high-quality beef broth. If you prefer a thinner sauce, skip the cornstarch slurry. To enhance the flavor further, broil the entire dish for a few minutes after slow cooking to achieve a nice char on the peppers.
