What Makes This Crock Pot French Onion Soup Recipe Easy?
The beauty of this recipe lies in its simplicity. The slow cooker does most of the work, allowing the onions to caramelize gently over several hours. This eliminates the need for constant stirring and attention, freeing up your time for other tasks. You'll achieve that deep, rich onion flavor without the usual hours of stovetop tending.
Ingredients You'll Need:
- 3 pounds yellow onions, thinly sliced
- 2 tablespoons olive oil
- 1 teaspoon salt
- 1/2 teaspoon black pepper
- 1/4 teaspoon sugar (optional, enhances caramelization)
- 6 cups beef broth
- 1 cup dry red wine (optional, adds depth of flavor)
- 2 bay leaves
- 1 teaspoon dried thyme
- 1 baguette, sliced
- 1 cup shredded Gruyère cheese (or Swiss cheese)
Instructions:
-
Caramelize the Onions: In your slow cooker, combine the sliced onions, olive oil, salt, pepper, and sugar (if using). Stir well to coat the onions evenly. Cook on low for 6-8 hours, or high for 3-4 hours, stirring occasionally to prevent sticking. The onions should be deeply caramelized and softened. This is the key to a truly delicious French onion soup!
-
Add the Broth and Seasoning: Once the onions are caramelized, pour in the beef broth and red wine (if using). Add the bay leaves and thyme. Stir gently to combine.
-
Simmer and Develop Flavor: Cook on low for another 2-3 hours, allowing the flavors to meld and deepen. The longer it simmers, the richer the soup will become.
-
Prepare the Croutons: While the soup simmers, preheat your oven to 350°F (175°C). Arrange baguette slices on a baking sheet and toast until lightly golden brown and crispy.
-
Assemble and Bake: Ladle the soup into oven-safe bowls. Top each bowl with a few toasted baguette slices and a generous amount of shredded Gruyère cheese.
-
Broil to Perfection: Broil in the preheated oven for 2-3 minutes, or until the cheese is melted, bubbly, and golden brown.
-
Serve and Enjoy! Carefully remove the bowls from the oven and serve immediately. The warm, bubbly cheese and crispy croutons complement the rich, caramelized onion soup perfectly.
