Ingredients for Mushroom Slow Cooker Roast Beef

• 3-4 pounds beef chuck roast
• 1 tablespoon olive oil
• 1 onion, diced
• 3 cloves garlic, minced
• 1 pound cremini mushrooms, sliced
• 1 cup beef broth
• 1/2 cup red wine (optional)
• 2 tablespoons Worcestershire sauce
• 2 tablespoons soy sauce
• 1 tablespoon Dijon mustard
• 1 tablespoon dried thyme
• Salt and pepper, to taste
• 2 tablespoons cornstarch (optional, for thickening)

How to Make Mushroom Slow Cooker Roast Beef

1. Season the beef chuck roast generously with salt and pepper.
2. Heat the olive oil in a large skillet over medium-high heat. Sear the roast on all sides until browned, about 3-4 minutes per side. Transfer the roast to the slow cooker.
3. In the same skillet, add the diced onion and cook until softened, about 5 minutes. Add the minced garlic and cook for an additional minute.
4. Add the sliced mushrooms to the skillet and cook until they release their juices and begin to brown, about 8-10 minutes.
5. Transfer the onion and mushroom mixture to the slow cooker, placing it on top of the roast.
6. In a small bowl, mix together the beef broth, red wine (if using), Worcestershire sauce, soy sauce, Dijon mustard, and dried thyme. Pour this mixture over the roast and vegetables in the slow cooker.
7. Cover and cook on low for 8 hours or until the beef is tender and easily pulls apart with a fork.
8. If desired, you can thicken the cooking liquid to make a gravy. Mix 2 tablespoons of cornstarch with 2 tablespoons of water to create a slurry. Stir the slurry into the cooking liquid in the slow cooker and cook on high for an additional 10-15 minutes, or until the gravy has thickened.
9. Serve the Mushroom Slow Cooker Roast Beef with mashed potatoes, rice, or crusty bread to soak up the delicious gravy.
