Before you start

Before beginning, organize all ingredients to ensure a seamless process. Slice the flank steak into thin, uniform strips against the grain, which is crucial for tenderness. Prepare the red bell peppers by removing the seeds and stems, then slicing them into strips that match the size of the beef.

Measure out the ground Szechuan pepper and prepare the stir-fry sauce so that everything is ready to be added to the slow cooker in quick succession to maintain temperature control.

Ingredients at a glance (4)
  • 1 1/2 lb flank steak, thinly sliced
  • 2 red bell peppers, sliced
  • 1 tbsp ground Szechuan pepper
  • 1 cup savory stir-fry sauce

Instructions

Layering the ingredients

  1. Prepare the Base
    Place the thinly sliced flank steak into the bottom of the slow cooker. Scatter the sliced red bell peppers evenly over the top of the beef to ensure even steaming during the cooking process.
    Look for ensure the beef is in a single layer at the bottom
    Tip slicing the beef against the grain will result in a more tender finished texture

The slow cooker should be clean and ready. The beef strips should be arranged in a single, even layer at the bottom, followed by the red bell peppers. Everything should look organized and ready for the seasoning phase, ensuring no ingredients are clumped together, which promotes even heat distribution once the cooking cycle begins.

Seasoning and braising

  1. Season and Cook
    Sprinkle the ground Szechuan pepper over the beef and peppers. Pour the savory stir-fry sauce over all ingredients. Cover the slow cooker and cook on low for 4 hours until the beef reaches an internal temperature of 145°F (63°C). Once cooked, let the meat rest for at least 3 minutes before serving.
    Look for the beef should be tender and the sauce should be fragrant
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip avoid lifting the lid during the cooking process to keep the temperature consistent

The Szechuan pepper should be sprinkled evenly to provide a consistent aromatic profile. The sauce should cover the ingredients completely.

Once the lid is secure, the internal environment will begin to build pressure and heat. Listen for a gentle bubbling sound, indicating the slow braise is underway and the flavors are beginning to penetrate the beef.

Final rest and serving

  1. Final Serving
    Once the beef has rested, gently stir the contents to coat the meat and peppers evenly in the sauce. Serve immediately while hot to enjoy the best flavor and texture.
    Look for the meat should be succulent and the peppers soft
    Tip serve immediately while hot for the best flavor experience

The beef should be tender to the touch, and the sauce should have a glossy, thickened appearance. The aroma should be savory and slightly citrusy from the peppercorns. After the 3-minute rest, the meat will be perfectly juicy, and the peppers will have reached a tender, melt-in-your-mouth texture, ready to be plated for serving.

Common mistakes

A common mistake is overcrowding the slow cooker or using pieces of beef that are too thick, which prevents uniform cooking. Ensure the beef is spread in an even layer. Another oversight is failing to slice the beef against the grain, which results in a chewy texture regardless of the cooking time.

Finally, do not lift the lid during the final hour of cooking, as this releases heat and moisture, which can lead to uneven results and extend the required cooking time significantly.

How to tell it’s done

The beef is done when it is fork-tender and reaches an internal temperature of 145°F (63°C). The meat should pull apart easily with minimal pressure, indicating that the connective tissues have broken down.

The red bell peppers should be soft and translucent, having absorbed the savory sauce. Ensure the beef rests for 3 minutes after cooking to allow the juices to redistribute, resulting in a more succulent and flavorful dining experience.
