Ingredients 

  • 2 lbs Chuck pot roast
  • 3 onions
  • 2 carrots
  • 3-1/2 cups plus 5 tbsp beef broth
  • 1 tbsp Worcestershire sauce
  • 1 tbsp apple cider or red wine vinegar
  • 1 tbsp Dijon mustard
  • salt and pepper
  • 1/2 tbsp onion powder
  • 1/2 tbsp garlic powder
  • 6-8 fresh thyme sprigs (or 1/2 teaspoon dried thyme)
  • 5 tbsp corn starch
  • 2 large slices bread
  • 1 tbsp extra virgin olive oil
  • 1/2 cup shredded gruyere cheese

Instructions

For the Pot Roast

  • Slice onions and carrots.
  • Heat olive oil in a large skillet.
  • Salt and pepper the roast on both sides. 
  • Sear both sides of the roast in olive oil. Remove from heat and let it sit in the skillet. 
  • Add 3-1/2 cups of beef broth to the slow cooker and add the onion powder, garlic powder, Worcestershire sauce, vinegar, and mustard and stir until combined. 
  • Add onions, carrots, and fresh thyme sprigs to the liquid in the slow cooker. 
  • Add the roast and any of the skillet juices. 
  • Cover and cook on high for 5 hours. 
  • When the roast is cooked, remove it from the slow cooker and place it on a cutting board. 
  • Remove and discard the fresh thyme sprigs.
  • Mix the cornstarch with the extra 5 tbsp of beef broth to make a slurry. 
  • Stir the slurry into the slow cooker with the onions, carrots, and broth. Cover and cook for about 15-20 minutes until the broth thickens. 

For the Cheese Toast

  • Preheat oven to 350°.
  • Slice 2-3 large pieces of bread about 1 inch thick.
  • Drizzle the bread with olive oil and bake for 15 minutes. 
  • Remove the bread slices and allow them to cool to room temperature. 
  • Increase oven temperature to broil.
  • Rub the top side of each slice with garlic clove. 
  • Top the bread with cheese and place under broiler until melted and bubbly. 

To Assemble the Platter

  • Place the cheese toast on a large platter, place the roast on top of the toast, spoon out onions and carrots, and place around the roast, spoon the entire platter with gravy liquid.
