Sterilize your jars and lids by boiling them in water. This step helps prevent the risk of bacterial growth during storage.
3. Fill Jars with Pressure Cooked Tomatoes
Once cooked, fill your jars with the tomatoes while still hot, leaving a headspace of about ½ inch at the top. This space is essential to allow for expansion during the canning process.
4. Seal and Process
Secure the lids tightly and place the jars in the pressure canner. Process according to your canner’s instructions, typically for 25-35 minutes. With tomatoes being low-acid foods, proper pressure canning is vital for preventing botulism and ensuring safety.
Common Mistakes to Avoid When Pressure Cooking Tomatoes
To achieve the best possible outcomes when preparing tomatoes, be aware of the following pitfalls:
1. Not Enough Liquid
A common mistake is not adding enough liquid. Always ensure there is sufficient water or broth to create steam pressure.
2. Overcrowding the Cooker
Pack too many tomatoes into the pressure cooker and risk uneven cooking or, in extreme cases, the cooker failing to reach pressure.
3. Ignoring Safety Features
Follow your pressure cooker’s safety instructions diligently. This includes ensuring the sealing ring is properly positioned and checking the pressure release valve.

What types of tomatoes are best for pressure cooking?
The best types of tomatoes for pressure cooking are typically the ones that can hold up well under heat and retain their flavor. Varieties such as Roma, San Marzano, and Beefsteak tomatoes are excellent choices. Roma tomatoes are particularly popular because they are meaty and have fewer seeds and less water, making them ideal for sauces and stews.
On the other hand, if you’re looking for a sweeter flavor, you might consider using cherry or grape tomatoes. They can add a burst of sweetness to your dishes and can be pressure cooked for a shorter time. Ultimately, the best variety will depend on your personal preference and the specific dish you’re preparing.
How do I prepare tomatoes for pressure cooking?
Preparing tomatoes for pressure cooking is a straightforward process. Start by washing the tomatoes thoroughly to remove any dirt or pesticides. If you’re using larger varieties like Beefsteak, you may want to core and quarter them. For smaller ones like cherry tomatoes, simply wash and leave them whole. If you prefer a smoother sauce, you can blanch the tomatoes briefly in boiling water to loosen their skins and then peel them.
After prepping, you could also consider seasoning the tomatoes with herbs, salt, or oils, depending on your intended recipe. This enhances the flavor and ensures that the cooking process infuses your dish with these seasonings. Finally, ensure that you do not overfill your pressure cooker. Leave enough space for steam to circulate, usually about two-thirds full.
What should I add to tomatoes when pressure cooking?
When pressure cooking tomatoes, you can enhance their flavor by adding various ingredients. Common additions include onions, garlic, herbs like basil or oregano, and spices such as red pepper flakes for a kick. Depending on the dish, you may also want to include other vegetables like bell peppers or carrots to create a more complex flavor profile.
Don’t forget to include some liquid to facilitate the cooking process. Water, vegetable broth, or even wine can be added to help create steam, prevent burning, and enhance the overall taste of the dish. Just be mindful not to add too much liquid, as tomatoes are naturally juicy, and can create excess moisture on their own.
How long should I pressure cook tomatoes?
The cooking time for tomatoes in a pressure cooker generally ranges from 5 to 15 minutes, depending on how tender you want them to be. For smaller, whole tomatoes, a cooking time of about 5-8 minutes is usually sufficient. For diced or crushed tomatoes, 10 minutes is often ideal. If you are making a sauce and prefer a softer consistency, you might want to increase the time slightly.
