Before you start

Before starting, ensure all ingredients are properly prepared. Cut the beef chuck into uniform 1-inch cubes to ensure they reach the safe internal temperature at the same time.

Slice the mushrooms evenly and chop the bacon into small pieces to distribute the smoky flavor throughout the dish. Have your slow cooker placed on a clean, stable surface near a power outlet, ready for the assembly of the components.

Ingredients at a glance (5)
  • 2 lb beef chuck, cut into 1-inch cubes
  • 8 oz mushrooms, sliced
  • 4 slices bacon, chopped
  • 1 packet au jus seasoning
  • 4 tbsp unsalted butter, sliced

Instructions

Ingredient Assembly

  1. Layering the ingredients
    Place the cubed beef chuck into the bottom of the slow cooker. Scatter the sliced mushrooms and chopped bacon evenly over the beef. Sprinkle the contents of the au jus seasoning packet over the mixture. Finally, arrange the butter slices on top of the other ingredients.
    Look for The ingredients should be layered evenly to ensure consistent cooking throughout the process.
    Tip Ensure the beef pieces are roughly the same size so they cook at a uniform rate.

At the end of this phase, the slow cooker should be filled with layers of beef, mushrooms, bacon, seasoning, and butter. Everything is ready for the long, slow heat to begin working its magic. Ensure the lid is securely placed on the unit before turning it on to the low setting, creating a sealed environment that will trap moisture and flavor effectively.

Slow Cooking Process

  1. Slow cooking the steak
    Cover the slow cooker with the lid. Cook on the low setting for approximately 4 to 6 hours. Ensure the internal temperature of the beef reaches at least 145°F (63°C) for food safety. Once cooked, let the meat rest at least 3 minutes before serving.
    Look for The steak bites are ready when they are fork-tender and the sauce has thickened slightly.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Avoid lifting the lid unnecessarily to maintain a constant temperature inside the slow cooker.

During the cooking phase, the kitchen will begin to fill with the savory aroma of beef, bacon, and mushrooms. By the end of this period, the meat should be deeply colored and tender. The liquid at the bottom of the slow cooker should be bubbling slightly and have transformed into a rich, flavorful sauce that is ready to coat the steak bites.

Resting and Final Presentation

  1. Resting and serving
    Once the cooking time is complete, transfer the steak bites to a serving plate, ensuring a good portion of the mushroom and bacon mixture is spooned over the top.
    Look for The meat should be dark, glossy, and steaming when removed from the pot.
    Tip Serve immediately while hot for the best texture and flavor profile.

After the resting period, the beef should be slightly firmer and perfectly moist. The final check involves ensuring the steak bites are properly coated in the pan juices.

The dish is now ready to be transferred to serving plates, where the combination of textures from the tender beef and the cooked mushrooms provides a satisfying and complete meal experience.

Common mistakes

A common mistake is cutting the beef into uneven pieces, which leads to some bites being overcooked while others remain tough. Another error is neglecting to let the meat rest after cooking, which is essential for the juices to redistribute, ensuring the bites stay succulent.

Additionally, resist the urge to open the slow cooker lid frequently during the cooking cycle, as this releases heat and steam, significantly increasing the total time required for the beef to reach tenderness.

How to tell it’s done

The steak bites are considered done when the beef is fork-tender, meaning it yields easily when pierced with a fork or knife. The internal temperature must reach at least 145°F (63°C).

The sauce should appear glossy and slightly thickened, coating the meat, mushrooms, and bacon bits. Always verify the temperature with a digital thermometer inserted into the thickest piece to ensure it is cooked through and safe to consume.
