Before you start

Before beginning, ensure all ingredients are ready for the slow cooker. Wash the bell peppers thoroughly and remove the seeds and stems. Slice the onions and peppers into uniform strips to ensure they cook at the same rate.

Prepare the beef by trimming any excess fat and slicing it into thin, consistent strips. Having everything prepped and ready to go makes the assembly process fast and efficient.

Ensure the slow cooker insert is clean and placed on a flat, stable surface away from any edges.

Ingredients at a glance (4)

  • 2 large bell peppers, sliced
  • 1 large yellow onion, sliced
  • 2 cups beef broth

Instructions

Prep and Assembly

  1. Prepare the ingredients
    Slice the beef into thin, bite-sized strips against the grain to ensure tenderness. Slice the bell peppers and onions into uniform strips so they cook evenly within the slow cooker. Arrange the beef, peppers, and onions in the bottom of the slow cooker insert.
    Look for The vegetables and meat are evenly distributed.
    Tip Cutting the meat against the grain is essential for achieving a tender texture.

At the end of this phase, the ingredients are neatly arranged in the slow cooker. Everything is sliced evenly, and the liquids are poured over the top. The slow cooker is ready to be covered and switched on to begin the cooking process.

Slow Cooking

  1. Combine and simmer
    Pour the beef broth over the beef and vegetables in the slow cooker. Cover with the lid and cook on low for 6 hours or on high for 3 hours. This slow cooking process allows the flavors to meld and the beef to become fork-tender. Ensure the beef reaches an internal temperature of 145°F (63°C) and let the meat rest for at least 3 minutes before serving.
    Look for The liquid is bubbling gently and the aroma is savory.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Do not lift the lid during cooking to maintain a consistent temperature.

During this phase, the kitchen will begin to fill with the savory aroma of the beef and peppers. The liquid will be simmering, and the ingredients will gradually soften. Everything should remain undisturbed to maintain a consistent internal temperature.

Resting and Serving

  1. Final serve
    Confirm that the beef has reached an internal temperature of at least 145°F (63°C) and let the meat rest for at least 3 minutes before portioning. Serve the hot pepper steak over steamed rice or noodles. Allow any leftovers to cool for no more than 2 hours before placing them in the refrigerator.
    Look for The sauce is glossy and the beef is tender.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip If a thicker gravy is desired, stir in a cornstarch slurry during the last 30 minutes of cooking.

The final phase concludes with the beef being thoroughly cooked and tender. The sauce is rich and glossy, coating the meat and vegetables perfectly. After a short rest, the dish is ready to be served hot over a preferred base.

Common mistakes

A common mistake is cutting the beef chunks too large or with the grain, which can result in chewy meat. Another error is opening the slow cooker lid too frequently, which releases heat and extends the cooking time, potentially leading to uneven results.

Finally, failing to trim excess fat from the beef can make the final gravy feel greasy. Ensure the ingredients are sliced correctly and trust the slow cooker to do its job without unnecessary interruptions.

How to tell it’s done

To determine if the dish is done, check that the beef is tender when pierced with a fork. Use a meat thermometer to ensure the beef has reached an internal temperature of at least 145°F (63°C), and allow it to rest for at least 3 minutes.

The vegetables should be tender but still hold their shape, and the gravy should be glossy and aromatic. Proper doneness is achieved when the meat easily pulls apart and the flavors are fully developed and well-balanced throughout the entire dish.

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