Slow Cooker French Onion Soup

"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,"

directions

  • 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!

  1. This is perfect as written. Made the full recipe (just fit in a 6 qt. slow cooker) and I'll be lucky if I get to freeze half. ;) Been looking for the perfect FO soup recipe and now I've found it - a plus being less complicated than others I've tried - thanks!
     
  2. Easy to make ... not too much fuss and tasted great, but mostly I Loved that it was not overly salty as many French Onion Soups are. I added quite a bit of pepper at the end to deepen the flavor though.
     
  3. Loved this recipe. I pared it down a little bit--just four pounds of onions and about ten cups of broth.<br/><br/>Just before serving it, I dished it out into ramekins. Then I sliced the French bread, laid a slice on top of the soup, but partially sticking out of the bowl too. I sprinkled mozzarella cheese over top (didn't have any other variety at the moment) and broiled it for about 3 minutes. Turned out perfect!
     
  4. YUM!!! I ran the onions through my mandoline for thinner slices. The house smelled so good while this was cooking! I've never made french onion soup and I'm glad that I chose this recipe! Thanks for posting, this was very tasty!

  1. 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.
