Before you start

Before beginning, ensure the beef is trimmed of any excessive hard fat, though a little marbling is desirable for flavor. Cut the beef into uniform, two-inch chunks to ensure even cooking. Wash and quarter the mushrooms, keeping them roughly the same size as the beef chunks.

Have all ingredients measured and ready, as the assembly process is very quick. Ensure your slow cooker is clean and placed on a stable, heat-resistant surface away from any splashes or direct heat sources.

Ingredients at a glance (4)
  • 2 lb beef chuck roast, cut into large chunks
  • 1 lb cremini mushrooms, quartered
  • 2 tbsp veal stock powder
  • 1 cup red port wine

Instructions

Initial Assembly

  1. Assemble the Ingredients
    Place the beef chunks into the bottom of the slow cooker insert. Distribute the quartered mushrooms evenly over the top of the beef. Sprinkle the veal stock powder over the mushroom and beef mixture.
    Look for Beef is arranged in a single layer at the base of the slow cooker.
    Tip Ensure the beef chunks are roughly the same size to promote even cooking throughout the process.

The beef should be arranged in a single layer to ensure even heat distribution. The mushrooms should be scattered evenly over the top, and the stock powder should be distributed to ensure seasoning coverage. The assembly should look clean and organized before the liquid is added.

Slow Braising Process

  1. Slow Braising
    Pour the red port wine over the ingredients. Cover the slow cooker with its lid and set it to low heat. Cook until the beef reaches an internal temperature of 145°F (63°C). Once cooked, remove the beef and let it rest for at least 3 minutes before serving.
    Look for The liquid should just barely cover the base ingredients, allowing the steam to braise the meat.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Do not remove the lid during the first 6 hours of cooking to maintain the necessary internal temperature.

During the cooking phase, the slow cooker should remain undisturbed. You will notice the aroma of the port wine and beef filling the kitchen. The liquid level will rise slightly as the beef and mushrooms release their natural juices, creating the braising broth.

Final Resting and Serving

  1. Final Resting and Serving
    Once the cooking time is complete, verify the beef has reached 145°F (63°C). Allow the beef to rest for at least 5 minutes before serving on a warmed plate to ensure the juices redistribute through the meat fibers.
    Look for The meat should pull apart easily with a fork and the sauce should appear glossy and dark.
    Safe temperature 145°F (63°C) internal temperature (steaks, chops and roasts)
    Tip Serve immediately while the dish is hot to enjoy the best texture and flavor profile.

After the cooking time, the beef should be incredibly tender and the sauce should have darkened into a rich, glossy finish. The meat should be rested for a few minutes to allow the juices to settle, ensuring each serving is moist and flavorful when plated.

Common mistakes

A common mistake is using a cut of meat that is too lean, which will result in a dry and chewy texture regardless of the cooking time.

Another frequent error is opening the lid too frequently, which causes a significant drop in temperature and adds unnecessary time to the cooking process.

Additionally, ensure the mushrooms are not sliced too thin, or they may disintegrate completely into the sauce during the long cook time, losing their pleasant, meaty texture.

How to tell it’s done

The beef is done when it is fork-tender, meaning it should offer no resistance when pierced and pull apart easily with minimal pressure. The internal temperature must reach at least 145°F (63°C) to ensure safety.

The sauce should be reduced and glossy, clinging to the back of a spoon. If the meat still feels firm, continue cooking in 30-minute increments, as individual slow cooker heat settings can vary significantly between different models and sizes.

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