How to Make Tomato Sauce for Canning
While normally we just boil, salt, and puree our tomatoes before canning, I recently because intrigued by the idea of a more seasoned tomato sauce.
I wanted to keep this tomato sauce recipe simple, yet find a way to deepen the flavor of the sauce at the same time.
This process turned out to be an easy one and within just a few days I had an easy and delicious garlic roasted tomato sauce recipe that was perfected for canning!
Step One:
First, take your tomatoes, whether fresh or frozen tomatoes, and wash them well. Then, place them in a single layer on a baking sheet.
Step Two:
Set your oven to 425°F. Meanwhile, season your tomatoes with salt, pepper, and garlic. You can use fresh chopped garlic, or garlic powder. Both are delicious, so just use what you have on hand!
Step Three:
Bake the tomatoes for about 45 minutes, or until the skin is wrinkled but not starting to burn. Take your lemon juice out of the fridge at this point, so it can come to room temperature before use!
Puree the tomatoes in a large pot and bring mixture to a low boil. Boil for 5 minutes then add to your jars for canning!
OPTIONAL STEP:
Some people like a very smooth tomato sauce with no skins or seeds. This is easy to do with a common canning tool! Just run the mix through a food mill and it will remove all the skins and seeds.
I personally like to leave the skins and seeds in the mix for added bulk and nutrients. But it's up to you!
Step Four:
Prep your canning jars by washing and heating them as desired to 250°. I like to do this in oven, but others like to boil their jars instead.
Step Five:
Add ROOM TEMPERATURE lemon juice to each jar, then ladle hot tomato sauce on top of the lemon juice. Leave a 1/2 inch headspace.
Step Six:
Wipe the rims of each jar to ensure a good seal (use a clean rag dipped in boiling water), and adjust rings and lids to finger tightness. Process in a water bath canner for 35 minutes.
Step Seven:
After processing is done, remove the jars from water bath canner and place on a fold dish rag on the counter. Allow to cool completely before moving - 12-24 hours.

What size bottle of lemon juice did you use? They come in different sizes.
Victoria says
Hi Steven! The size bottle you need will vary based on how many jars you are planning to can. The amount per jar is listed in the recipe, that way you can plan accordingly.
We can dozen of jars at a time, so I usually get several bottles of lemon juice. However, if you were only planning on a few pints, then you would just need a few tablespoons.
I hope that helps!

Hi Victoria ! I was curious about the purpose of the Lemon juice. I make a similar recipe all the time but I freeze it. Does the lemon juice help to preserve?
Victoria says
Hi Jennifer! Great question – the lemon juice is to make it canning safe. It raises the ph level so that it’s safe on the shelf! Hope that helps!
