Season 3 lbs boneless beef chuck roast generously with salt and black pepper. Optionally, sear the roast in 1 tbsp olive oil in a hot skillet for 3-4 minutes per side until browned, then transfer to your slow cooker. This step builds a rich flavor base for your Slow Cooker French Dip Sandwiches with Garlic Mushrooms.

Pour 4 cups low sodium beef broth and 2 tbsp Worcestershire sauce over the beef in the slow cooker. Sprinkle with 1 tsp garlic powder, 1 tsp onion powder, and 1/2 tsp dried thyme. Ensure the beef is mostly submerged in the liquid.

Cover the slow cooker and cook on low for 6 hours, or on high for 3-4 hours, until the beef is incredibly tender and easily shreds with a fork. This long, slow cook time is essential for the melt-in-your-mouth texture of the beef for your Slow Cooker French Dip Sandwiches with Garlic Mushrooms.

About 30 minutes before serving, melt 2 tbsp unsalted butter in a large skillet over medium heat. Add 1 lb sliced cremini mushrooms and cook until softened and golden, about 5-7 minutes. Stir in 4 cloves minced garlic and cook for another minute until fragrant.

Carefully remove the cooked beef from the slow cooker and shred it using two forks. Return the shredded beef to the aromatic jus in the slow cooker to keep it warm and moist. Split 8 hoagie rolls and lightly toast them under a broiler or in a pan.

Layer the shredded beef onto the toasted hoagie rolls. Top each with 8 slices provolone cheese and a generous portion of the Golden Garlic-Kissed Mushrooms. Place the assembled sandwiches under the broiler for 1-2 minutes, or until the cheese is melted and bubbly.
