What is passata and why should you make it yourself?
Making passata means preparing a thick, smooth tomato sauce from ripe tomatoes by cooking, straining, and seasoning them, without skins or seeds. You will find shelves full of bottles at the supermarket, but the taste of homemade passata based on sun-ripened, fresh tomatoes is simply unbeatable; passata is faster to use than fresh tomatoes as a base for sauce, soup, or pizza.
For home cooks, hobby gardeners, and tomato fans, this is a delicious way to process kilos of produce into a pure, natural sauce without unnecessary additives or preservatives. In this article, you will discover exactly what passata is, why making it yourself is so satisfying, which ingredients and kitchen tools you need, how to get started step by step, how to store passata, and what you can use it for in the kitchen. This way, you turn your surplus of tomatoes into jars. It just makes you happy, doesn't it?
To me, there is nothing like the moment when the whole house smells of gently simmering tomatoes. For me, making passata is the way to capture the pure, full taste of summer and carry it into the colder months. It is somewhat meditative: transforming beautiful, sun-ripened tomatoes from the garden into a smooth, deep-red sauce for the pantry. When I open a jar in the winter for a quick pasta sauce or pizza, I immediately taste those sunny summer days again. Pure, honest, and so much tastier than from the supermarket!
The benefits of making your own passata:
No unnecessary additives: Pure nature, without preservatives or excess sugars.
No waste from your harvest: Perfect for processing kilos of tomatoes from the vegetable garden at once.
Flavor bomb in stock: An ideal base for any pasta sauce, soup, or as a quick pizza base.
What do you need to make passata?
ripe tomatoes (ripe plum tomatoes like San Marzano or Roma are ideal)
salt (and possibly some fresh pepper)
water
Options for extra flavor: a dash of olive oil, a few sprigs of fresh basil, garlic, oregano, or thyme, plus a small spoonful of tomato paste for extra body and depth of flavor. That is a concentrated processing of tomatoes.
A large pot with a lid.
A food mill (passe-vite), hand blender, blender, or a tomato mill.
Clean glass jars or bottles with a well-sealing lid.
Step by step: how to make fresh tomato passata from ripe tomatoes
Making passata takes some time, but the result is pure cooking pleasure and a house filled with a wonderful tomato scent. You will thank yourself in the winter when you open a bottle and taste tomatoes at their peak.
Step 1: preparing and cutting your tomatoes
Wash the tomatoes thoroughly under cold water. Cut away any bruised or bad spots. Remove the stems. Cut the rest of the tomatoes into rough pieces. You do not need to remove the skin or the seeds beforehand!
Step 2: cooking and evaporating the moisture
Put the cut tomatoes into a large pot and add a small amount of water (about 50 ml) to prevent burning at the beginning. Place the lid on the pot and set it over high heat. Bring the mixture to a boil and stir regularly.
As soon as the tomatoes start to burst, turn the heat down and remove the lid from the pot. Let the tomatoes cook gently. The goal of this step is for excess moisture to evaporate and for the tomatoes to soften into a rich puree. This step takes about 45 to 60 minutes.
Step 3: sieve for a smooth texture
Now you will separate the pulp from the skins and seeds:
With a food mill (recommended): Scoop the cooked tomatoes into the food mill and turn the handle. The sieve keeps all the tough skins and seeds back, while the smooth mass is collected underneath. Repeat this until all the mixture has been processed.
With an immersion blender or food processor: Don't have a food mill? Puree the mass until very smooth with an immersion blender and then pour the mixture through a fine-mesh sieve.
Tip for thicker sauce: Is the sieved passata still a bit too watery? Put the collected sauce back into the pan for a moment over low heat and let it reduce briefly to the desired thickness.
Step 4: seasoning
Season the base sauce with a pinch of salt and some black pepper. Adjust the amount of salt to your taste during or after reducing. If desired, season with some finely chopped fresh basil and a drizzle of olive oil, and finish with a little extra pepper for a bit of kick. Do you prefer a neutral base sauce that you can use for any dish later? Then just add salt.
Storing passata: how to keep it fresh for months
Now that your fresh passata is ready, you can use it immediately in a delicious meal or freeze it. Want to keep the bottles or jars outside the fridge for a longer time? Then hygiene is crucial.
Sterilizing: Ensure that the glass jars and lids are sterilized. For example, run them through a hot cycle in the dishwasher or briefly boil them in hot water.
Filling: Pour the hot passata into the jars. Fill them up to about 1 cm below the rim.
Closing: Screw the lid on tightly. This will create a vacuum seal as it cools.
Canning: want to be completely safe? Then water bath can your bottles of passata for 30 minutes at 90°C. The timing starts once your water has reached temperature. Hot bottles = start with hot water.

Cooling: Let the jars cool down slowly to room temperature. Once they have completely cooled, you can store them in a dark, cool place (such as a pantry or cellar). Opened jars should naturally be kept in the refrigerator.
What can you use your homemade passata for?
Homemade passata is incredibly versatile in the kitchen and fits into all sorts of delicious dishes:
Rich pasta sauce: Heat the passata in a pan with some sautéed garlic, onion, and chopped herbs: this gives you a quick base for pasta sauces in a flash, ready to serve. Delicious with meatballs in passata!
Pizza base: Spread a thin layer of passata over your pizza dough for a traditional Italian pizza.
Lasagna: Passata is also a winner between the layers. Simple, full of tomato flavor, and wonderfully creamy.
Soups and stews: Use a few spoonfuls as a flavorful base for tomato soup or vegetable stew.

Tom made a video about making passata. In the video, you can see how he gets to work with a food mill. His daughters Ella and Sam love helping out and are super proud of their tomato sauce! Enjoy watching.
Frequently asked questions about making passata:
1. Which tomatoes are best to use for passata?
I prefer using fleshy tomato varieties with little moisture and few seeds, such as Roma tomatoes or San Marzano. Do you have a mix of ripe cherry or vine tomatoes from your own garden? No problem! As long as the tomatoes are nice and ripe and full of flavor, you can easily combine them.
2. Do I need to peel and deseed the tomatoes first?
No, fortunately not! That saves a huge amount of work. I simply cut the tomatoes into rough chunks and cook them, skin and all, until soft. If you then use a food mill (passe-vite), all the tough skins and seeds are left behind in the sieve, and you are left with a perfectly smooth sauce.
3. My passata turned out too watery, what can I do?
Don't panic; this happens to me sometimes when the tomatoes are very juicy. I simply put the sieved passata back in the pan over low heat. Let the sauce reduce slowly without a lid until enough moisture has evaporated and you have reached the desired thickness.
4. Can I also use an immersion blender or food processor instead of a food mill?
You can, but there is an important difference. A blender or immersion blender also grinds up the seeds and skins completely. This can give the passata a slightly more bitter taste and a less vibrant, bright red color. If you use an immersion blender anyway, pour the sauce through a very fine-mesh sieve afterward.
5. How long will my homemade passata stay good?
If I pour the hot passata into well-sterilized, clean glass jars and immediately tighten the lids (and turn them upside down briefly to create a vacuum), the passata will easily keep for 6 to 12 months in a cool and dark place. Once opened, I store a jar in the refrigerator and use it within a few days.
6. How do I best sterilize my mason jars or glass bottles?
I often run my glass jars and lids through the hottest cycle of the dishwasher, or I boil them for a few minutes in a large pot of boiling water. Make sure not to touch the inside with your fingers or a dirty towel after sterilizing.
7. Should I add herbs during cooking or only later?
I usually choose to keep my base passata very neutral with only a pinch of salt. This way, I can take the sauce in any direction later (for a Mexican dish, Italian pizza, or soup). If you want to add flavor right away, feel free to simmer a few sprigs of fresh basil, thyme, oregano, or some garlic along with it.
8. Is it necessary to add citric acid or vinegar for shelf life?
Tomatoes naturally contain quite a bit of acid, which helps with preservation. Are you making very large quantities that you want to store outside the fridge, and are you concerned about acidity? Then you can add a small drop of lemon juice just to be safe. In practice, thorough sterilization and hot-filling have always been sufficient for me.
9. Can I also freeze homemade passata?
Yes, that is a fantastic alternative if you don't feel like sterilizing jars! I let the passata cool completely on the counter first. Then I pour the sauce into freezer containers or bags. Don't forget to leave 1 to 2 centimeters of space at the top, because liquid expands when it freezes.
10. What exactly is the difference between passata, tomato paste, and tomato sauce?
Passata is raw or briefly cooked, sieved tomato (pure and fairly liquid/smooth).
Tomato paste is tomato mass that has been reduced extremely far, resulting in a very thick, concentrated paste.
Tomato sauce is an already seasoned, ready-to-use sauce (often with onion, garlic, and oil) that can go directly onto pasta. So, passata is the perfect building block for making your own tomato sauce!
