Simple Homemade Roasted Tomato Passata

A roasted tomato passata is the perfect way to preserve a glut of tomatoes and makes the perfect base for a host of stews and soups!

Roasted Tomato Sauce.

This recipe is firmly aimed at those that dabble with a little bit of gardening!

We harvest well over 100kg close on 250lb of tomatoes a year, passata is how we store lots of them.

Passata is strictly speaking uncooked passed tomatoes, but the first time I tried roasting it courtesy of an article at River Cottage I never went back.

You will see me using this stuff in everything from my chicken saag curry to pasta puttanesca.

For that reason, I keep the seasoning really very neutral. Just a little salt and pepper and a pinch of brown sugar.

When the jars are opened it then gets seasoned to match the dish.

This stuff is pure magic and the process is almost identical to the one that starts my roasted tomato soup recipe!

Preserving Tomato Sauce.

The internet rages with arguments about preservation and things that you must or must not do.

This recipe contains the preservation method that I use.

It has seen me well through the nearly 15 years making this recipe with no problems.

I do ALWAYS use fresh new lids and ensure that my jars are spotlessly clean before they are filled.

You also need to ensure that the jars are completely filled.

The most important part is the seal, so if a jar does not pop and clicks when you press the centre of the lid it is not right.

You need to use this immediately. If this happens after a jar has been set aside for a while, then you should dispose of the contents!

After you have opened a jar store it in the fridge and use within 5 days.

Made this today as had lots of tomatoes this week from my greenhouse. I made it with homegrown garlic and onions too, so satisfying! And it tastes far superior to shop bought stuff

Can you freeze this instead of using jars.

I don't see why not drop it into bags of a size that you usually use, get rid of as much air as possible, then seal and freeze. It should be good for up to 6 months at least!

1100 calories per serving? I think there's a typo in there somewhere...

Hi Polly, the calorific value refers to the entire recipe, it is in the notes below the recipe. I use a third party application to give indicative nutritional values and the only way for me to do it for the whole recipe is to set the serving size to 1 :)

Fab recipe and so good to read about the canning process which I was thinking was the way to go but everything I was reading was talking about the water bath faff.

Thank you
