As every home cook knows, Tomato paste is one of those ingredients you usually need in small amounts. You open a can for a tablespoon or two, then the rest ends up lingering in the fridge until it goes to waste.
A few days later, you find it pushed behind the yogurt, looking darker, drier, and very much not like something you want to stir into dinner.
That’s why freezing tomato paste has become one of my favorite kitchen habits! It saves money, cuts down on waste, and (when you freeze it in cute shapes) adds a teensy bit of whimsy to everyday cooking.
I started freezing tomato paste in a silicone heart-shaped ice cube tray, and each little heart holds about 1 tablespoon. Now, when I need some for soup, pasta sauce, chili, or stew, I can grab one from the freezer and drop it straight into the pot.
It IS practical, yes. But it is also a little whimsical. And honestly, I love that. Y’all know I love to add some whimsy to anything I can.
Why Freezing Tomato Paste Makes So Much Sense
Tomato paste is packed with rich tomato flavor, so most recipes only need a small amount. A spoonful can deepen a sauce, add body to a soup, or make a skillet dinner taste like it simmered longer than it did.
The problem is the packaging. When you buy tomato paste in a can, it is easy to use a little and forget the rest. Tubes help, but cans are still common and often far cheaper.
Freezing tomato paste solves that problem because it lets you portion it into useful amounts before it spoils.
It also reduces the ever crushing mental load of homemaking! Instead of planning meals around the thought of, “I need to use up this tomato paste soon,” you get to think, “I already have tomato paste ready whenever I need it.”
How to Freeze Tomato Paste in Ice Cube Trays
Freezing tomato paste takes just a few minutes. Once you do it, you will probably wonder why you did not start sooner.
What You Need
- Leftover tomato paste
- A silicone ice cube tray
- A spoon or small spatula
- A freezer bag or airtight freezer-safe container
- A marker for labeling, optional but helpful
Silicone trays work especially well because the frozen tomato paste pops out more easily. Plastic trays can work too, but you may need to let them sit at room temperature for a minute before removing the cubes.
Step-by-Step Instructions
- Spoon the tomato paste into the tray.
Add about 1 tablespoon to each cavity, or use whatever amount fits your tray. - Smooth it down slightly.
This helps the cubes freeze evenly and makes them easier to store later. - Freeze until solid.
Place the tray flat in the freezer for several hours, or overnight. - Pop out the frozen cubes.
Once the tomato paste is fully frozen, remove the cubes from the tray. - Transfer to a freezer bag.
Store the frozen tomato paste cubes in a labeled freezer bag so you can reuse the tray. - Use as needed.
Drop a cube directly into soups, sauces, stews, chili, or braises.
This method keeps the tomato paste portioned and easy to grab. It also frees up your ice cube tray for the next thing you want to freeze.
Another Way to Add Whimsy to Your Daily Routine
Before we get back to the tomato paste talk, I want to share something that fits this whole theme of making everyday tasks feel lighter: my podcast-style cleaning routines inside the Domestic Daydreams membership.
Think about how much easier cleaning feels when you have an audiobook, a cozy playlist, or a favorite tv show playing in the background. Now imagine that same comforting feeling, but with someone guiding you through each step of your routine! You press play, follow along in timed increments, and let the audio tell you what to do next.
Here’s how it works:
- You choose a cleaning routine and press play.
- I guide you through each step, one of my members said “It’s like cleaning with a friend!”
- The routines are timed, so you can move through your home without overthinking.
- Some routines are set to classic audiobooks, like Anne of Green Gables.
- Others include vintage radio shows from the 1940s and 1950s.
It is still cleaning, of course. But it feels less like dragging yourself through a chore!
AND I’m offering a 14-Day free trial of the membership, so you can try the podcast cleaning routines and see how they feel in your own home!
Because sometimes joy comes from the smallest things: a heart-shaped tomato paste cube melting into soup, or a cozy voice guiding you through the dishes! Click here to start your free trial!
You Can Use Any Ice Cube Tray Shape
The heart-shaped tray adds a little whimsy, but any ice cube mold will work just as well.
You can use:
- Standard square ice cube trays
- Mini cube trays
- Silicone molds
- Round molds
- Star shapes
- Seasonal shapes
- Any fun tray you already own
The main thing is knowing roughly how much tomato paste each cube holds. If you cook often, it helps to measure the first time. Fill one cavity with tomato paste, scoop it out, and measure it with a tablespoon.
Once you know the amount, you can use the cubes easily in recipes.
For example:
- 1 cube = about 1 tablespoon
- 2 cubes = about 2 tablespoons
- 3 cubes = about 3 tablespoons
If your tray makes larger cubes, that is fine too. You can still use them in recipes that call for more tomato paste, or cut a cube in half once it has softened slightly.
Ways to Use Frozen Tomato Paste Cubes
Frozen tomato paste works in almost any cooked recipe where you would normally use tomato paste. You do not need to thaw it first in most cases.
Just add the cube to a hot pan or pot and let it melt into the dish.
Try it in:
- Pasta sauce
- Chili
- Tomato soup
- Lentil soup
- Beef stew
- Vegetable stew
- Braised chicken
- Shakshuka
- Sloppy joes
- Curry
- Rice dishes
- Beans
- Meat sauce
- Roasted vegetable sauces
If you are sautéing onions, garlic, or spices, you can add the frozen tomato paste cube to the pan once the aromatics soften. Let it cook for a minute or two so the flavor deepens.
That little step can make a big difference. Tomato paste tastes richer when it gets a chance to cook before you add liquid.
A Common Mistake to Avoid
The biggest mistake is freezing tomato paste in the tray and leaving it there too long.
It may seem convenient, but it ties up your tray and can expose the paste to freezer smells over time. It can also make the tray annoying to use if you want it for ice, herbs, broth, coffee cubes, or anything else.
Instead, freeze the tomato paste until solid, then transfer the cubes to a freezer bag or airtight container.
Make sure to press out extra air before sealing the bag. Label it with the date if you want to stay organized.
You can write something simple like:
Tomato paste — 1 tbsp each
That way, you do not have to guess later.
Why This Tiny Habit Feels So Satisfying
Part of the appeal is practical: it keeps tomato paste from going to waste, makes meals easier to pull together, and saves you from opening a new can for just a spoonful.
But part of the appeal is emotional too.
Cooking can become repetitive. We chop the same onions, wash the same pans, and make the same weeknight meals when we are tired. Tiny details can make those routines feel a bit cozier.
For me, the heart-shaped tomato paste cubes do that.
They give me a small moment of joy every time I cook with them, and that little bit of whimsy makes everyday meals feel more special. Even if I’m the only one that knows about them. 😉
