Slow Cooker French Onion Soup

Slow Cooker French Onion Soup created by Robin and Sue

I made this fantastic recipe for a big batch of onion soup that You can freeze in portions to use later. Serve this with a lovely red wine and salad and voilà for a romantic meal. These are 14 large servings so if you are serving this before a meal reduce the amount of soup in your bowl. Better than bouillon also makes a great beef broth,

ingredients

  • Over medium heat sauté the onion in butter until soft and translucent and caramel colour. Make this in 3 batches.
  • Place onions in slow cooker.
  • Deglaze cooking skillet with some of the beef stock;this is the secret to that taste.
  • Add to slow cooker along with the remaining beef broth (your own homemade or powdered mixed with boiling water).
  • Add Worcestershire sauce, thyme and bay leaf.
  • Cover; cook on High for 4 hours or on low for 6-8 hours.
  • Add salt and pepper to taste. Remove bay leaf.
  • Divide soup into appropriate containers.
  • Seal and freeze.
  • When ready to enjoy your French Onion Soup.
  • Remove from freezer and place in a microwave dish with 2 tbsp sherry; heat for 5 minutes.
  • Add Parmesan cheese to your onion soup bowl. Place one slice of toasted bread over the cheese. Fill bowl with soup.
  • Top with shredded Gruyère cheese.
  • Place under broiler to melt your cheese.
  • Tip: When adding your ingredients to the slow cooker make sure they are all hot.
  • Use the processor to slice your onions. I once read 'If I use my food processor just to make onion soup it will be worth the cost".
  • Bon Appettit!

    You can make the caramelized onions in your slow cooker. It takes a long time but they turn out perfect. Food Network has a few recipes for caramelized onions. I have done that a few times now you can make a big batch and freeze some, there is a wonderful dip using the onions on there too by Katie Lee.

    What is this part of the recipe? " (your own homemade or powdered mixed with boiling water)." and what did anyone do as alternative to this? I am getting ready to make it now.

    This recipe is perfect! My slow cooker didn't have room for the full recipe, so I reduced by a third. I also used chardonnay rather than dry sherry, and it tasted perfect. Used Better than Bouillon for the beef stock, as it would have been expensive to buy several boxes of broth. This soup has very big flavor for very little effort, freezes well, and is fairly inexpensive to make. Definitely will be making this again soon!
