Great French Onion Soup takes time. And if you don’t have the time to stand and monitor a Dutch oven all day, make this Slow Cooker French Onion Soup. In a slow cooker, the onions melt with beef broth and butter to form a creamy, super-savory soup that will have your lips smacking. You’ll want to eat this Slow Cooker French Onion right out of the pot, but take the extra time to prepare the traditional toast-and-cheese topping—it will make you feel like you’re dining in a cozy French bistro.


• 4 yellow onions, skins removed and thinly sliced into rings • 4 tablespoons butter • 2 tablespoons garlic, minced • 8 cups beef broth • 1 bay leaf • 6 slices crusty french bread • 8 slices gruyere or swiss cheese


Step 1

Add the butter and onion rings to the largest pan/skillet you have.

Step 2

Saute the onions over medium-high heat until onions are translucent and start to brown, about 10 minutes.

Step 3

Cover and cook an additional 5 minutes longer to let them caramelize.

Step 4

Transfer the onions to the slow cooker.

Step 5

Add the garlic, broth, and the bay leaf. Cover and cook on high for 3-4 hours or on low for 6-8 hours or up to 10.

Step 6

30 minutes before serving, preheat the oven to 420 degrees F.

Step 7

Place the slices of bread in a single layer on a baking sheet.

Step 8

Place the bread in the preheated oven for about 5 minutes, then flip the slices over and return them to the oven until the bread is dried and crunchy, about 5 minutes more. Set aside.

Step 9

Set oven-safe bowls on the baking sheet. Fill each with soup from the slow cooker. Place 2 slices of swiss cheese, overlapping on top of the soup so the edges are hanging over the sides of the bowls.

Step 10

Bake the soups until the cheese is melty, about 10 minutes.

Step 11

Serve with the crusty bread and garnish with parsley.
