Despite the ongoing moving plans, I am still enjoying my late summer activity: preparing canned items, particularly tomatoes. Although I was somewhat forgetful all summer and hardly gave them water (luckily, I had a lot of good mulch from farming!), my tomato plants are now full of fruit. It is time to prepare some canned tomatoes. This way, we won’t waste anything during the winter.
While looking through the blog for the time needed to sterilize canned tomatoes, I was surprised there was no article about «canned tomatoes.» Honestly, I sometimes feel a bit foolish sharing another tomato sauce recipe… but then I thought it would be good to create a summary article about the various preservation methods, since there are at least four different ways, each with its own benefits. So, let’s begin with canned tomatoes! Introduction: Which tomatoes work best for canning?
Aside: what variety of tomato should you keep?
In theory, you can store all tomatoes in jars, just as you can mix varieties in jars. However, I have some advice:
- Roma is particularly suitable for sauces and crushes because it is very meaty.
- Cherry tomatoes are great for candied or crushed tomatoes.
- Save the ancient varieties to enjoy them in salads, they are very tasty and disappear once cooked.
- Avoid yellow tomatoes, which are too weak in flavor
Personal practice: My “crushed” type preserves are often a mix of Roma/cherry crops. Because these are the two types of plants that give a lot to the garden

Conclusion
As summer draws to a close, preparations take over our lives, but canned tomatoes offer a sense of tranquility and peace. Despite minimal watering and an easy, sustainable farming approach, the tomato plants have yielded abundant fruit. This bountiful harvest seems to beckon us to can—a way to bring the warmth and flavor of summer into the cooler months. Canning tomatoes is not just a practical task, but a seasonal tradition that blends effort, patience, and a sense of accomplishment.
The fact that there isn’t a single article dedicated to canned tomatoes highlights an important point: even the most familiar topics deserve new perspectives. While a single tomato sauce recipe might seem monotonous, a comprehensive overview of various canning methods offers far greater value. There’s more than one way to preserve tomatoes, and each method has its unique use in the kitchen. From whole, peeled tomatoes to tomato sauce and puree, to slow-roasted tomato paste, each method caters to specific culinary needs and taste preferences.
Understanding these differences changes making canned tomatoes from a regular task into a thoughtful, planned activity. Some techniques highlight ease and adaptability, allowing tomatoes to be preserved for future use in soups, stews, or sauces. Other methods concentrate on intensifying flavor, saving time on hectic winter evenings. The sterilization period, canning setup, and choice of tomato type all influence the final result. Stronger-fleshed types for sauces or juicier varieties for eating whole ensure better texture and taste even months later.
Beyond the practical details, canned tomatoes also hold sentimental value. Filling jars with homegrown tomatoes—especially after a weak harvest—shows a deep appreciation for nature’s ability to thrive and the perks of low-effort gardening methods, like thick mulch. It reminds us that often doing less can lead to more rewards.
In the end, canned tomatoes mean more than just stocking a cupboard. It’s about recording a season’s yield, preventing waste, and getting ready for the upcoming months. By trying out different preservation techniques and selecting the right types, anyone can maximize their harvest. This way, the tastes of summer can linger longer—sealed in jars, they can enhance the flavors of winter meals whenever needed.
