Ingredients

Scale

Meat

  • 2 lb Chuck Roast

Vegetables

  • 2 cups Red or Yellow Onion (thinly sliced)
  • 3 Garlic Cloves (minced)

Liquids and Sauces

  • 1 tbsp White Wine Vinegar
  • 1 tbsp Worcestershire Sauce
  • 1/4 cup Tomato Sauce
  • 1 cup Beef Broth

Seasonings and Herbs

  • 1 tsp Salt
  • 1 tsp Black Pepper
  • 1/2 tsp Fresh Thyme (chopped) or 1/4 tsp dried Thyme
  • 2 tsp Fresh Parsley (chopped)

Thickening Agent

  • 12 tbsp All-Purpose Flour or Cornstarch

Instructions

  1. Prepare the Sauce: In a small bowl, whisk together the tomato sauce, beef broth, minced garlic, thyme, Worcestershire sauce, and white wine vinegar until well combined. This mixture will infuse the pot roast with rich flavors during cooking.
  2. Season the Roast: Trim any excess fat from the chuck roast for a leaner dish. Season all sides of the roast evenly with salt and black pepper to enhance the meat’s natural flavors.
  3. Layer Ingredients in Slow Cooker: In the bottom of your slow cooker, spread half of the sliced onions. Pour half of the prepared sauce over the onions to create a flavorful base. Place the seasoned chuck roast on top of the onions, then evenly sprinkle the remaining onion slices over the roast. Finally, pour the remaining sauce over the top to keep the roast moist and tasty during cooking.
  4. Slow Cook the Roast: Cover the slow cooker and cook on high for 4 hours or on low for 7 hours, until the roast is fork tender and infused with the onion sauce.
  5. Make the Gravy: Once the roast is cooked, remove the meat and keep warm. For the gravy, take 1 tablespoon of cornstarch or all-purpose flour per cup of sauce from the slow cooker. Heat the sauce over low heat, stirring frequently, until it thickens slightly to a gravy consistency.
  6. Serve and Garnish: Slice or shred the pot roast and serve it over a bed of creamy mashed potatoes. Spoon the rich French onion gravy over the top and sprinkle with fresh parsley for a colorful and aromatic finish. Enjoy your hearty and delicious French Onion Pot Roast!

Notes

  • You can substitute cornstarch for all-purpose flour to make the gravy gluten-free.
  • For deeper onion flavor, caramelize the onions on the stovetop before layering in the slow cooker.
  • Leftover pot roast can be refrigerated for up to 3 days or frozen for up to 3 months.
  • Be sure to trim excess fat to avoid greasy gravy.
  • Adjust cooking times based on your slow cooker model as heat levels may vary.
