French onion soup and tomatoes add flavor to this delicious pot roast that is prepared in a slow cooker. Serve it with potatoes, a green vegetable, a tossed salad, and a whole-grain bread for a hearty weekday meal.


  • 1 boneless chuck pot roast (about 3 pounds)
  • Steak seasoning blend (to taste or salt and pepper to taste)
  • 2 tablespoons olive oil
  • 1 medium onion (peeled and sliced)
  • 8 ounces mushrooms (cleaned and sliced)
  • 1 can condensed French onion soup (undiluted)
  • 1 teaspoon Worcestershire sauce
  • 2 tablespoons ketchup
  • 1 (14.5-ounce) can diced tomatoes (undrained)

Steps to Make It

  1. Gather the ingredients.

  2. Rub the roast all over with the steak seasoning blend or salt and pepper.

  3. Heat olive oil in a large skillet over medium-high heat. Sear the roast on all sides, about 2 to 3 minutes per side.

  4. Transfer the roast to the crockery insert of the slow cooker.

  5. In the same skillet, sauté the onion and mushrooms over medium heat until the onions are lightly browned.

  6. Add the soup, ketchup, Worcestershire sauce, and diced tomatoes and their liquid, and bring to a boil. Pour over the roast in the slow cooker.

  7. Cook on HIGH for 1 hour.

  8. Turn to LOW and continue cooking for 7 to 8 hours, or until tender.

  9. Remove from the slow cooker and serve with boiled or mashed potatoes, using the pan juices as an unthickened sauce. If you desire, you can transfer the pan juices to a saucepan and stir in 1 tablespoon cornstarch that has been mixed with 2 tablespoons water until smooth. Whisk until the pan juices have thickened to make a thicker gravy.
