Roasting the tomatoes, garlic and onions makes this soup especially flavorful. After the veggies are roasted, all you need is 40 minutes and you've got a robust, rustic-style soup.
This recipe is from the America's Test Kitchen slow cooker episode. I'm not a fan of slow cookers, but this Beef Burgundy is soooo delicious and full of rich flavors you would never guess that it was made in a slow cooker, definitely a keeper!
