Most Southerners are a little bit in love with their slow cookers. The small appliances have an honored spot at holiday meals, they come along to tailgates, and when filled with hot appetizers, they are the life of the party. Every year, we publish dozens of new slow-cooker recipes, and the one that was the most popular in 2023 was a little bit unexpected, but nonetheless delicious: Slow-Cooker French Onion Soup.
Why Make French Onion Soup In A Slow Cooker?
You might be surprised to learn that you can even make this classic French soup in a slow cooker. Oui, you can!
As anyone who has ever stood at a stovetop patiently waiting for a pan of onions to caramelize knows, this soup can be time-consuming. The depth of flavor comes from tender, evenly browned onions, which can take an hour or more, depending on how many you are cooking. You simply can’t cut corners or rush the process.
Our hands-off recipe requires one initial stir to combine the ingredients, then another stir after the onions have started to brown. Your trusty slow cooker does the rest of the work for you—after 6 to 7 hours, the onions are meltingly tender and sweet and infused with flavor from thyme and a bay leaf.
How Do You Make The Topping?
But what about the cheesy top, you ask? For some, that’s the best part of a bubbling bowl of French onion soup. A layer of bread and cheese will get soggy in a slow cooker, so each serving is topped with a baguette slice with a layer of broiled Gruyere cheese. If you don’t have oven proof ramekins, place the cheese-topped baguette slices on a baking pan and broil them in the oven. Then place one slice atop each bowl of soup.
Why Do Southerners Love This Slow-Cooker French Onion Soup?
And according to the numerous five-star reviews of this recipe, this is a genius way to make French onion soup. “This was as satisfying and delicious as any I’ve had in a restaurant,” said one reviewer.
