Tips on making the best vegetable soup from frozen veggies:

One of my top tips on how to make a tomato based soup or sauce taste like it’s been cooking all day is to add balsamic vinegar! It cuts through that canned tomato taste like nothing else I’ve tried!

Another great way to add lots of flavor quickly to a dish is to use vegetable stock or vegetable broth. It instantly imparts so much flavor into a dish; so be sure not to skip this ingredient.

Substitution and FAQ’s

  • If you cannot find the frozen root vegetable blend, you can use frozen butternut squash or make your own root vegetable mix (see below)
  • Check your veggies and make sure they are about bite size or your soup will be hard to eat!
    • TIP: Look for chopped green beans or be sure to break them down by hand before adding them to the soup.

Tip on storing this frozen vegetable soup:

This soup is great to make for weekly meal prep. It’s simple to make and is super filling! It’s a great way to get your veggies, especially in the winter when you aren’t eating as much salad!

  • To store this soup in the fridge, simply store it in a air-tight container for up to 5 days. 
  • To store this soup in the freezer, portion it out into individual servings in freezer safe bags or containers. Once frozen, the soup will last about 3 months. Be sure to label the soup with the date it was made for easy reference. 
    • TIP: If you store this soup in freezer safe bags (like stasher bags) you can freeze them flat and stack them on top of each other once frozen. Freeze them on a rimmed baking sheet in case any of the liquid leaks out before completely frozen.

  • Heat a large soup pot over medium high heat.
  • Add the frozen veggies and cook 5 minutes, stirring occasionally. 
  • Add the rest of the ingredients and cover with a tight fitting lid. Cook 20 minutes over medium heat.


Substitutions for the root vegetable mix:
  • Frozen butternut squash or frozen sweet potato cubes
  • Make your own root vegetable mix by combining:
    • 1 cup of chopped sweet potatoes (2 small sweet potatoes)
    • 1/2 cup chopped parsnips (2 medium parsnips)
    • 1/2 cup chopped carrots (2-3 medium carrots)
    • 1/4 cup chopped red onion (about 1/2 of a large red onion)
Be sure that the frozen vegetables are chopped to bite size. I usually break the green beans up by hand to make them bite size. You can also look for chopped froze green beans at the store. 
This recipe can easily be doubled. Store the leftovers in the fridge for 5 days or in the freezer for up to 3 months.
