Back in September I made a bunch of slow cooker freezer meals. I spent a whole morning and afternoon chopping, sautéing, flash-freezing ingredients to have slow cooker meals at the ready come January. Okay, actually I planned to post these in October, but that month (and the rest of the year) entirely got away from me. PLUS now is the time where slow cooking is my go-to thing on earth.
Today I’m sharing with you one of my go-to freezer-friendly, slow cooking soups: Slow Cooker Italian Meatball Vegetable Soup! You know I’m on the fence with most slow cooker recipes. Some are simply blah to me. However, not this soup! It surely doesn’t taste like it was frozen 4 months ago and made in the slow cooker.
In this post I’m sharing how I went about making the prep kit. Then I share how I made it from the frozen stage. There is quite some prep involved, so having this freezer kit in the fridge helps. If you wanted to cook this the morning of, only add everything, including the broth into your slow cooker and set it on low and cook for 6 to 8 hours. Straightforward-peasy.
For this Slow Cooker Italian Meatball Vegetable Soup Set out:
- meatballs – about 24 meatballs 1-inch in diameter.
- dry red wine
- marinara – I used the recipe from my cookbook, but you can use this or any marinara you like.
- carrots
- yellow onion
- zucchini
- yellow squash – 1 to 2 of each depending on their size.
- mushrooms
- garlic
- red pepper flakes
I also recommend writing out the labels (if using them) in advance and placing them on the baggies before adding the ingredients. Write down ingredients that are in the bag, the ingredients set out day of in order to make the recipe and then any garnishes or ideas for serving, so when you pull out the bag to thaw, you can purchase any ingredients that you don’t have on hand. For me it was basil and crusty Italian bread.
For the meatballs I made a batch of my regular meatballs ever and used a tablespoon scoop to measure out the meatballs and then rolled them into balls. If you by chance have extra meatballs, simply flash-freeze them and save for another recipe. To flash-freeze, I place the rolled meatballs on a parchment lined rimmed, metal sheet pan and pop them into the freezer for 20 to 25 minutes. This will help the meatballs hold their shape when added to the freezer kit, so they won’t get smashed.
I bought a few of these clip storage bag holders (affiliate) which genuinely helped to hold my gallon ziplock bags upright, so I could add in all of the prepped ingredients. If you’re prepping a few recipes at a time, I would highly recommend buying a few of these babies, they are so handy!
For this slow cooker Italian meatball vegetable soup, I layered in the bag like this: marinara, wine, vegetables, minced garlic, red pepper flakes, and then added in the flash-frozen meatballs.
Lay the slow cooker Italian meatball vegetable soup freezer kit flat to freeze. This way I could stack more slow cooker freezer meals on top and maximize my freezer space. (oh and P.S. ignore that use by date 😉)
The morning before the day I plan to make it, I pull it out of my freezer and place it into the fridge to thaw for 24 hours at the minimum. I DO NOT recommend adding the completely frozen bag ingredients in to your slow cooker. Doing so may affect cooking times and the outcome of the soup. I also read a few opinions on putting food into the slow cooker from the freezer, that the contents might not reach a safe temperature to consume.
Day Of: Place the thawed (and maybe slightly slushy) ingredients into your slow cooker. Pour in 1 quart of low-sodium chicken broth and secure your slow cooker lid. Next, set to low and cook for 6 to 8 hours.
Once the soup is ready, season with 1-1/2 to 2 teaspoons kosher salt, 1/4 teaspoon freshly ground black pepper.
Then ladle the slow cooker Italian meatball vegetable soup into bowls.
Serve with freshly grated parmesan cheese, fresh basil and extra black pepper, if you’re into it.

Ingredients
FOR THE FREEZER KIT:
- 24 meatballs (rolled into 1-inch balls)
- 2½ cups marinara (kitchen-made or store-bought)
- 1/3 cup dry red wine (like merlot, Malbec or pinot noir)
- 1 medium yellow onion (diced)
- 1 to 2 zucchinis (depending on size, quartered and sliced)
- 1 to 2 yellow squash (depending on size, quartered and sliced)
- 1 to 2 carrots (sliced)
- 8 ounces cremini mushrooms (quartered)
- 1 clove garlic (minced)
- 1 to 2 pinches red pepper flakes (optional)
DAY OF:
- 4 cups low-sodium chicken (or vegetable broth)
- 1½ to 2 teaspoons kosher salt
- freshly ground black pepper (to taste)
TO SERVE:
- Fresh basil leaves
- 1/2 cup grated parmesan cheese
Method
FREEZER INSTRUCTIONS:
- 1
Use a tablespoon scoop to measure out the meatballs and roll into balls. Place on parchment paper on a medium, rimmed, metal baking sheet and arrange the meatballs in one even layer. Flash-freeze for 20 to 25 minutes. (while the meatballs flash-freeze I will prep the veggies)
- 2
Meanwhile, in a large gallon-size freezer-safe sealable bag, add in the marinara, wine, onion, zucchini, yellow squash, carrots, mushrooms, garlic and red pepper flakes (if using). Add the flash-frozen meatballs and seal half of the way closed.
- 3
Carefully squeeze out as much of the air as possible before sealing the bag all of the way. Lay flat to freeze, this makes it easier to store and for stacking other slow cooker freezer meals. Store in your freezer for 3 to 4 months, possibly longer:).
TO PREPARE:
- 4
Remove the Slow Cooker Italian Meatball Vegetable Soup bag from the freezer the day before you plan to make it. I found that if I take it out the morning before the actual day I plan make it, it will have plenty of time to thaw out. I DO NOT recommend adding the completely frozen bag ingredients in to your slow cooker, doing so may affect cooking times and the outcome of the soup.
- 5
Unzip the baggie and empty the contents into your slow cooker (discard the bag) and pour in 1 quart of low-sodium chicken or vegetable broth. Cover and cook on low for 8 hours. Before serving season with kosher salt and freshly grated black pepper
- 6
Serve with fresh basil, Parmesan cheese and crusty Italian bread.
From the cook
It's handy to label the freezer kit meal with what's in the kit and what is needed the day of, along with any cooking and serving instructions.
