Recipe preparation for Slow Cooker French Onion Soup

How to Make Slow Cooker French Onion Soup

Slice the Onions: Begin by thinly slicing your onions. A sharp knife helps speed things along and avoids tears—unless you’re watching a sad movie at the same time.

Caramelize Your Onions: In a skillet over medium heat, melt some butter and add onions. Cook until they’re golden brown and fragrant, about 20-30 minutes—resist stirring too often; patience is key here!

Add Ingredients to Slow Cooker: Transfer those glorious onions into your slow cooker. Pour in the beef broth, add thyme sprigs and bay leaves, then season generously with salt and pepper.

Cook Low and Slow: Cover your slow cooker and set it on low for about 6-8 hours. The house will smell heavenly—try not to drool too much!

Prepare Toppings While Waiting: About 30 minutes before serving, toast slices of baguette until golden brown. Top each slice with grated Gruyère cheese—because more cheese equals more happiness.

Broil the Topped Baguette Slices: Place the cheese-laden bread under the broiler until bubbly and slightly browned, about 3-5 minutes; keep an eye on it!

Now you’re ready to ladle that luscious soup into bowls. Top each serving with a cheesy baguette slice so you can bask in its glory as you dig in.
