Ingredients
  

  • 3-4 lb beef chuck roast (or bottom round)
  • 2 tsp kosher salt
  • 1 tsp black pepper
  • 1 tbsp neutral oil (for searing, optional)
  • 1 large onion, sliced
  • 3 cloves garlic, minced
  • 2 cups low-sodium beef stock
  • 1 tbsp Worcestershire sauce
  • 1 tbsp tomato paste
  • 1 tsp dried thyme (or 3–4 sprigs fresh)
  • 1 leaf bay leaf
  • 2 tbsp cornstarch (or flour)
  • 2 tbsp water (for slurry)
  • thick-cut toast and mashed potatoes, for serving

Instructions
 

  • Pat roast dry; season with salt and pepper. Optional: sear in hot oil 3–4 min per side until deeply browned.
  • Add onion, garlic, stock, Worcestershire, tomato paste, thyme, and bay leaf to slow cooker. Nestle roast inside.
  • Cover and cook on Low 8 hours (or High 5–6) until fork-tender.
  • Remove roast to rest. Whisk cornstarch with water; stir into crock juices. Cook on High 10–15 min until glossy gravy forms; season to taste.
  • Slice or shred beef. Serve over toast with mashed potatoes and ladle gravy over everything.

Notes

Chuck shreds best; bottom round slices neatly. If skipping sear, add 1 tsp soy sauce for deeper savoriness. Keep on Warm for serving.
