Why Make a Concentrate?

When you’re a busy mom like me, simple lunch meals really lighten your load. But I want them to be healthy, hardy and homemade. 

So, I started creating a menu of recipes that I could make in batches and freeze. Then it would be easy to pull out whenever we need it. 

For the longest time, my oldest daughter’s favorite thing has been tomato soup. She’s never had it from a store, and keeping homemade tomato soup on hand all the time is hard unless it’s canned or frozen. 

In the summertime when tomatoes were fresh, I would make big batches of tomato soup concentrate and freeze them in one cup portions or less, to reheat and reconstitute with milk. 

It worked so well! 

I’m still doing it, even if I don’t have fresh tomatoes. 

Here’s the recipe I came up with that’s always a winner for my kids, easy to throw together, blend in the pot, and freeze in individually sized portions.

Just thaw on the stove and add milk to serve for an easy lunch! We like to pair it with classic grilled cheese sandwiches, a hot dog from pasture-raised animals, or some left-over meat.

All of the ingredients you will need to make Frozen Tomato Soup Concentrate for an easy meal.

What You’ll Need To Make Tomato Soup Concentrate

  • Equipment: A 6-quart pot should do it. And an immersion blender.
  • Diced tomatoes: The star of the show! Any fresh or canned tomatoes would work well here.
  • Butter: The butter in this recipe gives the final soup a richer, creamy flavor.
  • Tomato paste: A can of tomato paste really adds the concentrated tomato flavor.
  • Onion & Garlic: Sauté these in the butter for another great depth of flavor.
  • Whole Milk: You’ll add this right before serving. If you freeze the concentrate, you won’t need it right away!
  • Bone Broth: Adds a nutritional boost and liquid to all the veggies.
  • Sweet Potato/Squash/Carrots: Your choice, fresh, frozen or canned – adds some thickness and sweetness to the soup.
  • Spices: Salt, pepper, and oregano are all you need to compliment this soup.

How To Make Frozen Tomato Soup Concentrate For Easy Meals

  1. Heat a large pot over medium heat with the butter.
  2. Add the chopped onion and cook for 5 minutes until softened, stirring regularly.
  3. Add the garlic, salt, pepper, oregano. Stir and add diced tomatoes, tomato paste, sweet potato, and broth.
  4. Stir together and cook for 15 minutes, covered, until the onion is very soft.
  5. After the soup has cooked, use an immersion blender to liquify everything.
  6. Taste for seasonings, cool, and transfer to freezer containers.
  7. To eat immediately, transfer a few cups of soup to a smaller pan and add about 1/2 cup milk to every 1 cup of tomato soup concentrate.

Freezing Instructions

After your soup is done, you can freeze it into smaller portions to pull out when you want it.

I like to use silicone muffin cups, or Souper Cubes. Muffin cups hold about 1/3 of a cup. And you can get Souper Cubes in a variety of sizes.

You can also freeze it in whatever size portions and containers work best for you! Just make sure you have a rough idea of how much it holds, so you know about how much milk to add when you reconstitute it.

I usually fill one 1-cup tray of Souper Cubes and however many muffin cups that leaves me. That way, I have a lot of possibilities with how much I get out at one time. For one kid, I might only need to thaw one muffin cup, but for 2 or 3, I’ll pull out a full Souper Cube or two.

How to Use and Dilute Frozen Tomato Soup Concentrate

I thaw each portion of concentrate quickly in a small saucepan on the stove, but you could also use the microwave if you wanted to.

I always eyeball the milk, and you might like more or less depending on your preferences, but it usually comes to about a 1:2 ratio of milk to soup concentrate. Just enough to cool it down again.

FAQs

Here are some quick answers to help you make, freeze, and use your tomato soup concentrate with ease.

Absolutely! And it will taste even better. However, converting fresh tomatoes to canned equivalents isn’t an exact science, as factors like tomato variety and ripeness influence the final volume. When substituting fresh tomatoes, aiming for approximately 4 pounds of fresh, fully ripe tomatoes is a good starting point. You may need to use a higher powered blender to puree the seeds at the end.

This is prepared to freeze and reconstitute with milk at a later time.

Definitaly dilute it, but read on for other options for use!

Yes! I’ve thawed a small chunk to use for a single serving pizza, just by adding some extra Italian seasoning. Essentially, you could add portions of the concentrate for use in any recipe calling for tomatoes!

Absolutely. Every 1 part dried = 3 parts fresh. So for ½ teaspoon dried oregano, you’d use: 1½ teaspoons fresh oregano (chopped).

That would be fine, especially for a low FODMAP diet.


You could sauté your veggies in garlic-infused olive oil for flavor without the FODMAPs (safe because the FODMAPs aren’t fat-soluble). Or use leek greens or chives for an onion-like flavor. Then, thaw and reheat with lactose-free milk, almond milk, or FODMAP-friendly broth.

You might like to add some smoked paprika or chili powder to spice things up a bit! The sweet potato really adds a nice whole food sweetness but other refined sugar alternatives would be: Maple Syrup – Mild, earthy sweetness; start with 1–2 tsp per batch.
Honey – Pairs well with tomatoes but can change the flavor slightly.
Coconut Sugar – Subtle and caramel-like, melts well into soups.

I think some good filling additions could be: cream, precooked ground meat, precooked beans, grated cheese, a scoop of collagen powder, or chopped hard boiled eggs.
