How to Make French Onion Soup Slow Cooker

Now that you have your ingredients ready, let’s dive into making this delightful French Onion Soup Slow Cooker. I promise it’s easier than it seems, and the result will absolutely warm your heart!

Step 1: Prepare the Onions

Start by slicing those large yellow onions into thin strands. I like to think of it as creating delicate ribbons of flavor! In your slow cooker, combine the sliced onions with the unsalted butter, olive oil, salt, and sugar. Stir everything gently until the onions are well-coated. This mixture is the foundation of your soup—trust me, it’ll be worth it!

Step 2: Slow Cook the Onions

Cover your slow cooker and set it to low. Let the onions cook undisturbed for about 6 hours. Yes, you heard me right! During this time, make sure to stir it occasionally to help them caramelize evenly. Those onions will transform from everyday vegetables into gorgeous, golden-brown treasures that smell heavenly!

Step 3: Add Garlic and Seasonings

Once the onions are perfectly caramelized, it’s time to add in the minced garlic. Give it a good stir! Allow it to cook for an additional 15 minutes to let those flavors mingle. Next, toss in the thyme, bay leaf, and Worcestershire sauce. Add freshly ground black pepper to taste, and stir again. The aromas here? Absolutely incredible!

Step 4: Incorporate the Broth

Now it’s time for the magic! Pour in the beef broth and the optional dry white wine for that extra depth. Give it a gentle stir, ensuring the broth is well mixed with your delicious onion base. Cleaning the spoon with your mouth is acceptable here—just saying!

Step 5: Final Cooking Time

Cover the slow cooker once more and let it cook on low for another 30 minutes. This step allows all those beautiful flavors to meld together. Trust me, the wait is so worth it. Your kitchen will be filled with a comforting scent that feels like home!

Step 6: Broil and Serve

As the cooking time wraps up, preheat your broiler. Toast the slices of French bread until they’re golden brown and crispy. Once your soup is done, remove the bay leaf. Ladle the soup into oven-safe bowls, placing a piece of toasted bread on top. Sprinkle generously with Gruyère cheese. Pop these under the broiler for 2-5 minutes until that cheese is melty and bubbly. The result? Comfort food heaven! Serve it warm and watch everyone dive in.

Tips for Success

  • Slice your onions uniformly for even caramelization; it makes a difference!
  • Don’t skip stirring the onions occasionally; it prevents burning and promotes even browning.
  • Feel free to use vegetable broth for a vegetarian version without compromising flavor.
  • Add a splash of sherry for extra depth if you desire.
  • Keep a close eye on the broiler to avoid burning that delicious cheese topping!

Equipment Needed

  • Slow Cooker: The star of the show; any size will do, but a 6-quart is ideal.
  • Sharp Knife: A good quality knife makes slicing onions a breeze.
  • Cutting Board: Essential for safely slicing and dicing.
  • Measuring Cups and Spoons: For the precise ingredient amounts.
  • Oven-safe Bowls: Perfect for serving; ramekins work great too!
