Ingredients

Scale

Main Ingredients

  • 4 lb. chuck roast
  • 21 oz. Campbell’s French onion soup (two 10.5-oz cans), do not add water
  • 3 Tbsp. Worcestershire sauce
  • 2 large sweet yellow onions, sliced
  • 1 tsp. dried thyme
  • 1 tsp. garlic powder
  • 1 tsp. salt
  • ½ tsp. black pepper

Serving Suggestions

  • Mashed potatoes
  • Slices of cheesy bread

Instructions

  1. Prepare the Slow Cooker: Place the 4 lb. chuck roast into the slow cooker, ensuring it lays flat to cook evenly.
  2. Add Liquids and Sauce: Pour the 21 oz. Campbell’s French onion soup directly over the roast followed by 3 tablespoons of Worcestershire sauce. Do not add any extra water to maintain the intense flavor.
  3. Add Onions and Seasonings: Spread the sliced sweet yellow onions over the roast, then sprinkle 1 teaspoon dried thyme, 1 teaspoon garlic powder, 1 teaspoon salt, and ½ teaspoon black pepper evenly across the top.
  4. Cook the Roast: Cover and cook on the LOW setting for 9 hours. The roast should become very tender and easy to shred with two forks after this slow cooking process.
  5. Finish and Serve: Once cooked, shred the meat using two forks directly in the slow cooker. If needed, skim excess fat from the sauce using paper towels for a cleaner finish. Serve hot with mashed potatoes and cheesy bread if desired.

Notes

  • Do not add water to the French onion soup; the soup serves as both seasoning and liquid.
  • If you prefer less fat, degrease the cooking liquid using paper towels before serving.
  • This recipe can be prepped the night before—just add all ingredients to the slow cooker insert, cover, and refrigerate until ready to cook.
  • Leftovers can be stored in an airtight container in the fridge for up to 3 days or frozen for up to 3 months.
  • For a thicker gravy, remove the meat after cooking and simmer the sauce on the stovetop to reduce before serving.
