The French Onion Soup works especially well as a substitute for beef broth in a variety of recipes.

Ingredients You Need

ingredients for slow cooker pot roast
  • Beef Chunk Roast – Choose a 3 to 4 pound chunk roast. Other cuts of meat will not be as tender.
  • Vegetables – Yukon gold potatoes, carrots and onions cook with the beef roast.
  • Campbell’s® French Onion Soup – The soup is a great substitute for beef broth in a roast and helps create even more flavor and keeps the beef moist.
  • Water or Beef Broth – This adds more liquid for cooking.
  • Spices – Fresh thyme, garlic, salt and pepper enhance the flavor of this dish.
  • Balsamic Vinegar – If you don’t have this, you can skip it. It adds a depth of flavor to the roast.
  • Olive Oil – This helps sear the beef.
  • Cornstarch – This is optional but preferred to thicken the broth to a gravy-like consistency.

Slow Cooker Pot Roast Tips

  1. Browning the beef is key to the best flavor. Sear the beef on all sides before adding to the slow cooker with the vegetables. This helps lock in flavor and juices.
  2. Use fresh onions and garlic. Do not use dried onion or garlic powders as they do not add the same amount of texture or flavor.
  3. Cook low and slow for the best results. You can cook on high in a pinch but the results will not be the same.
  4. Thicken the broth with cornstarch to make gravy. Do this at the very end of cooking for the best results.

Other Methods for Cooking

Pot Roast in the Oven

First, sear the beef in a large Dutch oven. Set the beef aside on a plate. Sauté the garlic for 30 seconds in the pot, then add the French onion soup and balsamic vinegar. Whisk in the cornstarch and let it thicken for about 4 minutes. Add the remaining ingredients, bring to a simmer, cover with a lid and transfer to an oven preheated to 325 degrees F. Roast for 3 to 4 hours, or until the meat is falling apart. A 3 pound roast takes about 3 hours to cook, while a 4 to 5 pound roast takes about 4 hours.

Pot Roast in the Instant Pot

Set an Instant Pot to ‘Saute’ mode. Add olive oil to the pot. Once the oil is hot, sear the beef on all sides until browned. Add the remaining ingredients and cook on manual HIGH pressure for 60 minutes. Allow the pressure to natural release for 15 minutes and then release any remaining pressure manually. Carefully remove the lid and serve.
