French onion soup is flavorful and hearty. Simply prepare the soup in a lined slow cooker to warm and allow flavors to meld, and you’ll have a comforting and delicious French Onion Soup.

Ingredients:
5 tablespoons unsalted butter
5 large yellow onions, sliced (1/4-inch-thick slices)
1 tablespoon brown sugar
3 sprigs fresh thyme
Pepper, to taste
3 tablespoons all purpose flour
1/4 cup soy sauce
2 cups chicken stock
2 cups beef stock
1/2 pound grated Gruyere cheese
1 loaf Sourdough bread (optional)

Prep:

1. LINE your 5- to 6-quart slow cooker with a Reynolds^® Slow Cooker Liner.
2. MELT butter in a large pot over medium heat. Add the onions, brown sugar, thyme and pepper and cook, stirring frequently, until the onions are very soft and caramelized, about 25 minutes.
3. ADD flour, stir to evenly coat onions.
4. Remove from heat and stir in soy sauce.

Cook:

1. ADD caramelized onion mixture into slow cooker. Add the beef and chicken stocks, cover with lid, set slow cooker to high heat and cook for 3 hours, or until soup is hot.
2. REMOVE and discard thyme sprigs.
3. LADLE into bowls and top with cheese. Serve with sourdough bread (optional).

Reynolds Kitchen Tip: Lining your slow cooker with a slow cooker liner ensures those sweet, caramelized onions make it to your belly and don’t get stuck to your slow cooker so you won’t have to spend precious time soaking and scrubbing when the meal is finished.
