Before you start

Before starting, ensure the slow cooker bowl is clean and dry. Prepare the flank steak by slicing it into uniform, bite-sized strips, ensuring all cuts are made against the grain to maximize tenderness.

Measure out the ginger, chili flakes, and orange sauce so they are ready for assembly. Clear a small space on the counter near the slow cooker for easy access during the preparation process, making the assembly quick and efficient.

Ingredients at a glance (4)
  • 1 1/2 lb flank steak, sliced into thin strips
  • 1 tbsp minced ginger
  • 1 tsp chili flakes
  • 1 cup orange sauce

Instructions

Preparation and layering

  1. Prepare the ingredients
    Place the thinly sliced flank steak strips into the bottom of the slow cooker bowl. Ensure the meat is spread out in an even layer to promote consistent cooking.
    Look for meat is evenly distributed
    Tip Slice the steak against the grain to ensure maximum tenderness in the finished dish.

At this stage, the flank steak strips should be arranged in a single, even layer at the bottom of the slow cooker. This ensures that the heat is distributed evenly across all pieces of meat. Check that the ginger and chili flakes are distributed across the surface of the beef before adding the sauce to ensure the flavors are well-integrated throughout the entire dish.

Seasoning and initial integration

  1. Season the beef
    Add the minced ginger and the chili flakes directly over the beef strips. These aromatics will infuse the meat with flavor as it cooks slowly in the sauce.
    Look for aromatics are evenly scattered
    Tip Freshly grated ginger provides a more vibrant and punchy flavor compared to dried powder versions.

The ginger and chili should be evenly scattered over the beef. As the sauce is poured over the top, it should begin to settle around the meat. Ensure the sauce covers the beef completely. At this point, the slow cooker is ready to be covered and started. There should be a pleasant aroma of ginger and citrus starting to form as the ingredients begin to settle.

Slow cooking to final glaze

  1. Slow cook the beef
    Pour the orange sauce over the seasoned beef, ensuring everything is well coated. Cover and cook on low for 4 hours until the beef reaches an internal temperature of 145°F (63°C). Let the meat rest for 5 minutes before serving.
    Look for sauce is bubbling and beef is tender
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Checking the internal temperature ensures the meat is perfectly cooked through without becoming overly chewy.

After four hours, the beef should be tender and the sauce should have thickened into a glossy, fragrant coating. The meat should look dark and infused with the orange color of the sauce.

Verify the internal temperature with a thermometer. The final dish should be steaming, with a balanced aroma of orange and subtle heat from the chili flakes, ready to be served immediately.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the sauce from coating the meat properly and may lead to uneven cooking. Avoid lifting the lid repeatedly during the cooking process, as this releases heat and moisture, significantly increasing the total time required.

Additionally, failing to slice the beef against the grain often results in a chewy, tough final product that is difficult to enjoy, regardless of how long it is cooked.

How to tell it’s done

The beef is done when it is fork-tender and pulls apart easily with a slight tug. Use a digital meat thermometer to ensure the internal temperature of the thickest piece of steak reaches at least 145°F (63°C).

This temperature confirms the meat is safe to eat while maintaining a succulent, juicy texture. Always allow the meat to rest for at least 5 minutes after removing it from the slow cooker to redistribute the juices.

  • Steaks, chops and roasts: 145°F (63°C) in the thickest part, then a 3-minute rest
