Before you start

Before beginning, ensure the beef is cut into uniform, bite-sized chunks to promote even cooking. Peel and slice the yellow onions into consistent strips, which will help them break down into the sauce.

Have the dark stout beer at room temperature to prevent a sudden drop in the slow cooker temperature when added. Clear a clean workspace and have your slow cooker positioned on a stable, heat-resistant surface near a power outlet.

Ingredients at a glance (4)
  • 2 lb beef chuck roast, cut into chunks
  • 2 large yellow onions, sliced
  • 1 cube beef bouillon cube, crumbled
  • 12 oz dark stout beer

Instructions

Layering the ingredients

  1. Assemble the base
    Place the beef chuck chunks into the bottom of the slow cooker. Scatter the sliced onions evenly over the beef, then sprinkle the crumbled bouillon cube over the top to season the mixture.
    Look for Beef is evenly distributed at the bottom.
    Tip Ensure the onions are spread out to provide a bed for the meat to cook in.

The beef is arranged in an even layer on the bottom of the cooker, covered by the onions and the crumbled bouillon. Everything is ready to receive the liquid, ensuring a balanced distribution of flavors before the slow cooking process begins.

Slow braising

  1. Add liquid and slow cook
    Pour the dark stout beer over the beef and onion mixture. Cover the slow cooker and cook on low for 8 hours until the meat reaches an internal temperature of 145°F (63°C). Once cooked, let the meat rest for at least 3 minutes before serving.
    Look for Beef pulls apart easily with a fork.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Do not lift the lid during the first 6 hours to maintain the consistent internal temperature.

The beer has been poured over the ingredients, and the slow cooker is set to the appropriate heat. The kitchen begins to fill with a savory, malty aroma as the beef slowly braises in the liquid, becoming tender over the extended duration.

Final rest and service

  1. Rest and serve
    Carefully remove the tender beef from the slow cooker and let it rest for at least 5 minutes before serving to ensure the juices redistribute throughout the meat.
    Look for Beef is glossy and steaming.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Serve with the reduced liquid from the slow cooker as a natural au jus.

The beef is tender, glossy, and fully cooked. After resting for five minutes, the meat is ready to be served, having absorbed the rich flavors of the stout and onions, resulting in a perfectly succulent and flavorful main dish.

Common mistakes

Avoid lifting the slow cooker lid frequently during the cooking process, as each time the lid is opened, heat escapes and the cooking time increases significantly.

Do not use an overly lean cut of beef, as it will likely dry out during the long cooking time; beef chuck is best because of its marbling.

Finally, do not overcrowd the slow cooker, as this prevents the heat from circulating properly around the ingredients.

How to tell it’s done

The beef is fully cooked and ready when it reaches an internal temperature of at least 145°F (63°C). Visually, the meat should be very tender and easily shredded with a fork.

The sauce will have thickened slightly, appearing glossy and dark, while the onions should be completely translucent and soft. Always verify the temperature with a meat thermometer inserted into the thickest piece of beef to ensure safety.

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