Ingredients

Scale

Main Ingredients

  • 3-4 lb chuck roast
  • 1 tablespoon olive oil
  • 1 packet (1 oz) dry onion soup mix
  • 2 cups beef broth
  • 1 cup French onion soup (canned or homemade)
  • 2 large onions, thinly sliced
  • 3 cloves garlic, minced
  • 1 tablespoon Worcestershire sauce
  • 1 teaspoon dried thyme
  • 1 teaspoon black pepper
  • 3 tablespoons unsalted butter

Optional Ingredients for Thickening

  • 2 tablespoons cornstarch
  • 2 tablespoons water

Garnish

  • Fresh parsley, for garnish (optional)


Instructions

  1. Sear the Roast: Heat olive oil in a large skillet over medium-high heat. Sear the chuck roast on all sides until well browned, about 3-4 minutes per side, to develop flavor and lock in juices.
  2. Transfer to Slow Cooker: Place the seared roast in the slow cooker to prepare for slow cooking.
  3. Prepare the Sauce: Sprinkle the dry onion soup mix evenly over the roast. In a separate bowl, whisk together beef broth, French onion soup, Worcestershire sauce, dried thyme, and black pepper. Pour this mixture over the roast in the slow cooker.
  4. Add Onions and Garlic: Arrange the thinly sliced onions and minced garlic around and on top of the roast, distributing evenly for full flavor infusion.
  5. Slow Cook: Cover the slow cooker and cook on LOW for 8-10 hours or HIGH for 4-5 hours, until the meat is fork-tender and easily shredded.
  6. Enhance the Flavor: Stir in the unsalted butter at the end of cooking to add richness and a silky texture to the sauce.
  7. Thicken the Sauce (Optional): For a thicker gravy, mix cornstarch and water in a small bowl until smooth, then stir this slurry into the slow cooker. Cook on HIGH for an additional 10-15 minutes until the sauce thickens to your liking.
  8. Serve & Garnish: Serve the tender pot roast with the flavorful onion sauce over mashed potatoes, rice, or crusty bread. Garnish with fresh parsley for a pop of color and freshness, if desired.

Notes

  • To achieve the best flavor, searing the roast before slow cooking is essential.
  • Cooking times may vary depending on your slow cooker model; check for fork-tender meat as an indicator.
  • If using homemade French onion soup, ensure it has a rich beef broth base for optimal taste.
  • Leftover pot roast can be refrigerated for up to 3 days or frozen for up to 3 months.
  • For a gluten-free version, verify the dry onion soup mix and Worcestershire sauce are gluten-free or substitute accordingly.
  • Thickening the sauce with cornstarch is optional but recommended if you prefer a gravy-like consistency.
