    Onion and Mushroom Soup

    I warned you! I'm on a soup kick!

    Every Christmas Eve for the past few years I've made a batch of homemade French onion soup and served it alongside crab legs, steamed shrimp, fried fish and roasted cauliflower. It's a fun tradition we all look forward to for different reasons. The Husband goes nuts for the shrimp. The 8-year-old can eat his weight in crab legs and the 2-year-old is a cauliflower fanatic.

    Me?

    I love the soup!

    This year the soup came out amazing. Better then amazing, perfect in my opinion. The mushrooms were a fantastic addition and really reduced the need to add bread or crackers.

    Here's what I did...

    Ingredients

    • 1 tablespoon butter
    • 1 tablespoon coconut oil (You can use olive oil if you don't have it)
    • 2 large sweet onions
    • 2 red onions
    • 1 cup good quality red wine (one you would drink)
    • 1 lb mushrooms
    • 32 oz (1 carton) beef broth

    Instructions

    Heat a soup pot over medium heat and add the butter and oil. Slice one of the onions as thinly as possible.

    Add them to the pot and sprinkle a little salt.

    Repeat with each onion, layering them with a pinch of salt in the pot.

    Once finished, stir them all together and let them slowly cook over medium to medium-low heat for at least 1 hour, stirring about every 20 minutes.

    We made cookies while waiting.

    After an hour the onions will have reduced and darkened in color.

    At this point I decided to use the pound of mushrooms I got in my farm share.

    I roughly chopped them and added to the onions with the 1 cup of wine.

    I let the mushrooms and wine cook down for about 10 minute before adding the beef broth.

    After adding the beef broth, I brought everything to a boil and then lowered to a simmer until I was ready to serve.

    You could eat it as is or add some cubed bread and top with a slice of cheese melted under the broiler.

      I made this soup and it was DELICIOUS and crazy easy to make. I don't love mushrooms, so I excluded those. It was exactly what I needed as I try to get over a bug!

      That looks SO good!...have never actually made FOS before despite loving it.....may give it a whirl this weekend as it's that time of year again where the cold makes you want hearty food!, but will def' require some chunky fresh bread & a generous amount of melty cheese!! (ooop's!)

        I don't see why not. Maybe a splash of balsamic in the onions to help deepen the flavor.

      Made this for dinner last night (Meatless Monday - but OK I used chicken stock) and it was delicious. Beyond delicious and easy. Just took some time and patience with the onions but so worth it and loved the addition of the mushrooms. Will definitely try it again and next time with the beef stock.

      Yum that looks great. Some provolone or Swiss would go great on the top.
