To Make This Spicy Sausage Soup you’ll Need:

  • Large stock pot or dutch oven
  • Sharp knife
  • Cutting Board
  • Large wooden spoon
  • Ladle
  • 2 tbsp olive oil
  • 1 onion diced
  • 2 stalks celery diced
  • 2 carrots diced
  • 1/4 cup garlic diced
  • 1 lb andouille sausage sliced into rounds
  • 2 zucchini sliced into thin half rounds
  • 8 oz cremini mushrooms sliced thin
  • 1 tsp dried oregano
  • 1 tsp salt
  • 1 tsp cumin
  • 32 oz beef broth

How to Freeze Andouille Sausage and Vegetable Soup

Since this soup uses easy to find ingredients – that are very inexpensive when buying in bulk – it is a great soup to make ahead in a big batch and freeze in portions, especially if you’re making a low carb soup for one.

Not all vegetables freeze and thaw well, so I am giving my top tips to a delicious soup both fresh from the stove – AND reheated from frozen!

Don’t cook soup all the way to done if you’re freezing it – and try to brown your vegetables quickly, so they are browned but not soft.

Reduce soup some, but leave a good amount of liquid, so that when you reheat the soup you can reduce it more.

Cool soup completely, then ladle into large freezer ziploc bags.

For easier defrosting, lay the bags flat on a cookie sheet and freeze until set – about 5 hours.

When soup is frozen flat, you can move it around the freezer wherever you have more room.

Keep frozen for up to three months.

To heat from frozen, let thaw naturally in refrigerator.

Add to stock pot, and bring to a low rolling boil.

Serve and enjoy!

  1. This soup is sooo good! I did chicken broth instead of beef. I also added a cup of heavy cream for a little bit of thicker consistency. I also added two potatoes at the beginning with the onions. This is a good base recipe that you can change to make your own!!!

    1. I am one of those people who cant get enough garlic – but you can easily cut the garlic in half (or less) according to your tastes.
