Homemade Ketchup

Instant Pot Ketchup Using Fresh Tomatoes

Canning season is almost over for me, except for the tomatoes. We had planted some Roma tomatoes this year along with some Big Boys. As I have mentioned before, our garden is too big to just eat from it daily and almost too small to do any BIG batches of anything. I had a large bowl of both of these tomatoes and I wanted to make some ketchup with them. I have my Grandma’s ketchup recipe, but for the life of me, I couldn’t find it anywhere! I just remember it had sugar and vinegar in it.
I love using my Instant Pot for doing my beets and spaghetti sauce, so why couldn’t I use it to make ketchup? It was worth a try!

I started out with a little over 6 lbs of tomatoes that were washed, stems removed, and cut into quarters.

I put them into the stainless steel insert of my 8 quart Instant Pot and set the pressure cook for 10 minutes.
After the 10 minutes, I did a 15 NPR (let the pressure come down naturally) and then finished releasing the pressure by turning the seal to vent until the pressure has fully released and the pin drops.

I then used my immersion blender to blend the tomatoes. If you don’t have an immersion blender, you can do this in a regular blender, just be careful of the hot liquid.

The skins help thicken the ketchup!

After everything is well blended, I then put the sauce through a fine mesh strainer/colander to remove the seeds and skins.

Discard the seeds!

The next step is to put the strained juice back into the Instant Pot and then add your spices.

Full recipe for the spices you will use will be at the end of this post.

After you add all the spices, sugar and vinegar turn the Instant Pot to Sauté! The Sauté function only stays on for 30 minutes, so I had to set mine two times for a total of 60 minutes. One nice feature is that it will be beep when the 30 minutes is up. If your ketchup isn’t thick enough at this stage, just continue to sauté until it is. This will depend on the type of tomatoes you use, some may be more watery than others.

You can see how much the sauce has reduced in volume!

I plan on water canning mine so it will be shelf stable. There is enough vinegar in the recipe that it will allow you to water bath can it. I prepared my pint jars and lids. This batch gave me 3 pints of ketchup.
When I’m doing a small batch of water canning, I just bring out my stock pot, add the trivet from my Instant Pot on the bottom and place my jars on the trivet. You don’t want the jars setting on the the bottom of the pot. Cover with enough water so it is 1″ over the top of the jars. I will process mine 15 minutes once the water starts to boil. Check your altitude for the time you need. If you don’t know, just process 20 minutes and you will be good!

Water Bath canning method!

This is the Instant Pot I use! I like the size of my 8 qt, especially when I am canning, it allows me to do bigger batches!
