Before you start

Before starting, ensure your slow cooker is clean and placed on a stable, heat-resistant surface near an electrical outlet. Have all ingredients measured and ready to go to make the assembly process efficient.

Take the beef out of the refrigerator about 15 minutes before you begin to take the chill off, which helps with even cooking. Ensure you have a sharp knife and a cutting board ready for prepping the leeks, and have your measuring tools at hand to ensure the correct ratio of stock to water.

Ingredients at a glance (4)
  • 1 1/2 lb beef chuck, cut into 1-inch cubes
  • 3 large leeks, cleaned and sliced
  • 2 tbsp veal stock powder
  • 1 cup water

Instructions

Preparation

  1. Prepare the Ingredients
    Clean the leeks thoroughly to remove any grit and slice them into thin rounds. Cut the beef chuck into uniform 1-inch cubes to ensure even cooking throughout the slow cooker process.
    Look for The leeks should be clean and sliced, and the beef cut into bite-sized pieces.
    Tip Soak the sliced leeks in a bowl of cold water for a few minutes to release any hidden dirt.

At the end of this phase, the beef should be cut into even 1-inch cubes and the leeks should be sliced and cleaned. Everything should be ready for the slow cooker, and your workspace should be organized. Ensure that the beef pieces are roughly the same size to promote uniform cooking, and that all grit has been successfully removed from the leeks to avoid any unpleasant texture in the final dish.

Assembly

  1. Assemble the Dish
    Place the prepared beef cubes at the bottom of the slow cooker. Arrange the sliced leeks evenly over the beef. Sprinkle the veal stock powder over the ingredients and pour in the water.
    Look for The slow cooker should look full but not overflowing with the beef and leeks submerged in the liquid.
    Tip Ensure the stock powder is distributed evenly to create a consistent savory flavor.

The slow cooker should be layered with the beef at the bottom, topped with the leeks, and seasoned with the veal stock powder. The water should be poured over the top, ensuring the ingredients are well-distributed.

At this stage, the ingredients should look neatly layered and ready for the long, slow cook. Double-check that the slow cooker is plugged in and set to the correct low temperature setting before placing the lid on securely.

Cooking and Resting

  1. Slow Cook and Serve
    Cover the slow cooker and cook on low heat for 8 hours until the beef reaches an internal temperature of 145°F (63°C). Let the beef rest for at least 3 minutes before serving to ensure the meat is tender and juicy.
    Look for The beef should be fork-tender and the liquid should be glossy and thickened.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip If the sauce is too thin, you can remove the lid for the final 30 minutes to reduce it.

Once the cooking time is complete, the beef should be tender and the sauce should have a rich, glossy appearance. The aroma should be savory and inviting. After checking the internal temperature of 145°F (63°C), ensure the meat is allowed to rest for 3 minutes. The liquid will have developed a deep flavor, and the leeks should be completely soft, indicating that the dish is perfectly cooked and ready to be served.

Common mistakes

A common mistake is overcrowding the slow cooker, which can prevent the beef from cooking evenly and may lead to excess liquid that does not reduce properly. Another error is failing to clean the leeks thoroughly; always slice them and rinse them in a bowl of water to ensure any trapped dirt is removed.

Additionally, avoid adding too much water, as the beef and leeks will release their own moisture during cooking. Finally, resist the urge to open the lid frequently, as this disrupts the temperature.

How to tell it’s done

The beef is done when it is fork-tender, meaning it should pull apart easily with minimal pressure. Use a digital meat thermometer to verify that the internal temperature of the thickest piece of meat has reached at least 145°F (63°C).

The sauce should be glossy and slightly thickened, with the leeks having melted into the liquid. Allowing the meat to rest for at least 3 minutes after checking the temperature is crucial for the juices to redistribute, ensuring the beef remains succulent when served.
