This easy roasted tomato and garlic sauce will become a staple when you want a delicious fresh sauce to serve over your favourite pasta. Store in the fridge or batch cook and freeze.

Easy Pasta Sauce
When I spot tomatoes on sale, especially in the summer I grab quite a lot as this sauce is so easy fresh and delicious.
If you are lucky enough to grow tomatoes too then you will make this sauce again and again and a variety of different types of tomatoes are even better.
Best Tomatoes for Pasta Sauce
Undoubtedly the best types of tomatoes for a pasta sauce has to be roma, especially Italian San Marzano tomatoes. But I find baby grape tomatoes or cherry tomatoes are equally delicious too.
For a roasted pasta sauce, it's so easy because I don't even both peeling the tomatoes. So it's a win win all round.
What other ingredients are needed?
Usually copious amounts of extra virgin olive oil are added to any roasted vegetables. But for my easy recipe and to keep the calories as low as possible I use a little bit of olive oil spray and then some stock.
The stock adds flavour to the sauce and keeps the garlic and onions from burning without having to use all that oil.
Onions are a must for any roasted sauce and I use a whole bulb, yes a whole bulb or garlic, it's not overpowering, instead as it roasts in the stock it softens and has a delicious sweet taste that just is heavenly. Pasta sauce is just not complete without garlic.
of course if you do want to add in a tablespoon or two of olive oil, then by all means do, it will add a few more calories, but will also add even more incredible depth and flavour to the sauce.
How long will the sauce last?
This roasted tomato and garlic sauce will serve about 4-6 people depending on how much sauce you like over your pasta.
It keeps for just about 1 week in the fridge or is perfect for freezing. I recommend freezing in portions so you have some on hand for one person quick meals if needed. Nothing worse than having to defrost the whole lot if you don't need it all.
Best dish for roasting vegetables for sauce
I always use baking trays, you can get them in a variety of different sizes and they just ensure you can spread out all the ingredients evenly and get perfect cooking.
If you cram everything in a small dish it won't roast evenly and you won't get those yummy flavours.
I do line with some parchment paper, this just ensures easy clean up afterwards.

If I replaced the sugar with sweetner would it be free? x
purplefeet says
I was wondering about the sweetner too 🙂
slimadmin says

Honor says
Maybe a stupid question but is tomato paste the same as tomato puree or is it something different?
Shevy (Slimming Eats) says
it sure is, called paste in the US/Canada but puree in the UK.
