Tomato & Roasted Red Pepper Vegan Pasta Sauce

Tomato & Roasted Red Pepper Vegan Pasta Sauce

Pasta is the ultimate comfort food. There are so many types of pasta and so many different sauces, it never gets boring. Today I'm sharing a rich tomato and roasted red pepper pasta sauce which is vegan.

I have a favourite tomato sauce we eat regularly. It's easy to make and has a rich sweet tomato flavour. We all love it, but it was time to change it up.

This time I wanted to make a tomato sauce with roasted red peppers and roasted red onions, but I didn't want the sauce to be dominated by the roast vegetable flavour, so I decided to make my fresh tomato sauce first and then add the roast vegetables at the end, so you get a burst of that smoky roast vegetable flavour in pockets as you eat the pasta, but you still have that rich sweet tomato flavour.

Cooper requested spaghetti with this sauce. I would normally choose penne or conchiglioni (shell pasta) for this type of sauce as they really fill up with sauce, but actually this was really good.

Ironically even though he requested it, Cooper decided he would prefer it with penne. Apparently only bolognese (or bolognaise, whichever you prefer) is good with spaghetti. There's no pleasing some folk.


I stocked up on pasta and some standby pasta sauces when I was in M&S this week. They have a new promotion on their pasta range. Buy one get on half price on pasta and pasta sauces.

M&S pasta is an Authentic Italian pasta made and sun dried in the Italian alps by the Felcetti family, using select Italian wheat, so you know it's going to be good.

Pasta Sauce

A selection of M&S vegetarian and vegan pasta sauces

I bought a range of veggie sauces from their range. Most of them are suitable for vegans, from what I could see on the labels, but some like the tomato and mascarpone are veggie not vegan.

Tomato & Herb,  Tomato & Sweet Garlic, Arrabbiata, Napoletana and Tomato & Basil are all £2.00 a jar, so with the promotion that comes in at £3 for 2 jars.

Cherry Tomato & Balsamic and Tomato and Mascarpone are £2.20 each.

Yes, I bought all that pasta. Well if it's on special offer .......

They are all suitable for vegans apart from the egg tagliatelle.

The conchiglioni (shell pasta), spaghetti, farfalle (bow tie pasta), orzo (mini grains of pasta good for salad and soup), messicani (we call this belly button pasta and use it in pasta salad) and fiorelli (tubes with a fluted edge) are all £1.60 and the egg tagliatelle is £1.80.

I saved £7.30 when I bought my pasta and sauces, so it's well worth stocking up.

M&S also stock wholemeal pasta, but my boys just don't like it. Mind you we haven't tried it for years so maybe it's time to try again.

What do you think of wholemeal pasta?  Do you prefer it?

I added a little spice and warmth to my dish with a generous pinch of paprika and one of chilli powder, but you could ramp up the chilli if you like. I wouldn't put too much paprika in as it can drown out the other flavours if you put too much in.

My other tip is to add a slosh of wine to the sauce to give it richness.  The alcohol burns off as it is cooked, but gives a great flavour. However, I know not everyone likes to add wine, so that is optional.

Roasting vegetables

I roasted my vegetables while the sauce was cooking and started to boil my pasta water. It's quite an art to have everything ready same time, isn't it?

Once the vegetables were roasted and soft but not too charred, I added them to the pasta sauce and tossed it all through the drained spaghetti.

I'd planned to add some fresh basil to the sauce at the end of the cooking time, but I completely forgot. It was delicious without it, but add it if you have some.

When you serve your pasta top it with some freshly grated Parmesan. There are vegetarian and vegan versions of Parmesan (the original is not suitable for vegetarians).  The vegetarian version of Parmesan is often in a supermarket basic range and called Italian hard cheese or pasta cheese and Violife do an excellent vegan version of Parmesan that has that tang you want.

I do hope you try my pasta sauce and enjoy it as much as I did.

Tomato & Roasted Red Pepper Vegan Pasta Sauce

A rich spaghetti sauce, sweet with the flavour of tomatoes, with some warmth from a little spice and the smoky flavour of roast red peppers and red onions. Suitable for vegans.
prep time: 10 minscook time: 30 minstotal time: 40 mins


  • a spray of olive oil, plus extra for
    roasting vegetables
  • 1 large white onion, chopped
  • 2 cloves garlic, crushed
  • a generous pinch of paprika
  • a generous pinch of chilli powder
  • 2 x 400g tins of chopped tomatoes
  • a slosh of red wine
  • 3 tbsp tomato puree
  • a good grinding of salt and pepper
  • 1 long romano red pepper or large red bell pepper, deseeded and cut into chunks
  • 2 medium red onions, peeled, halved and cut into wedges


  1. Preheat the oven to 220c/200c fan/425f/Gas 7.
  2. In a large pan, saute the onion and garlic in some olive oil until soft and translucent, then add the spices and mix in.
  3. While the onions are cooking spread the prepared peppers and onions across a baking tray. Spray them with a little oil and season with black pepper, then pop in the oven roast for 20-25 minutes until soft but not too charred.
  4. Once the onions are soft and you've added the spices, add the tomatoes, tomato puree and wine, then cook on a medium heat, stirring occasionally for 20 minutes until the sauce has thickened. Season with salt and pepper.
  5. While the vegetables and sauce are cooking bring your pasta water (in a large pan) to the boil.  Add the pasta 12 minutes (or less, check the packet) before the end of cooking time, stirring from time to time to prevent sticking.
  6. Stir the roast vegetables into the tomato sauce and pour the drained pasta into the sauce, stirring well to coat.
  7. Serve topped with veggie or vegan style Parmesan.

If you like this tomato and roasted red pepper spaghetti sauce, you may also like my veggie bolognese sauce which we've been enjoying for over 25 years now.

We were veggie back then, but it's amazing how much veggie food is actually vegan too. My mother-in-law first showed me how to make this sauce when Graham and I started dating and I was invited over for meals. It's so good I still make it regularly.

Disclosure: I'm helping to promote M&S vegetarian and vegan ranges. I was not expected to write a positive review and any opinions expressed are my own.


  1. I love the idea of roasting the veg and adding them to the sauce - I do it sometimes with pumpkin but the pepper and red onion combination is one I would not think of. And I love seeing how much pasta you buy - I don't use it as much as I used to but still love to stock up as it lasts ages. E really love wholemeal pasta but I think it only works in some dishes.

    1. Oh pumpkin is a good idea. I don't usually stock up on so much pasta, but as it was on special offer it seemed like a good idea.

  2. Pasta is totally the ultimate comfort food! I love adding roasted red peppers to tomato sauce - it adds such a great flavor!

    1. Yes I agree with you on both of those Danielle :)

  3. Sounds like a delicious and healthy pasta sauce. I've not tried whole meal pasta. But we have a brand here that makes a white fiber pasta that I really like.

    1. Thanks. I haven't heard of white fibre pasta before.

  4. Homemade pasta sauce always seems to have much more flavor than store bought. Will have to give your recipe a try!

  5. This recipe sound so amazingly flavorful! I've always been too scared to try making my own pasta sauce, but maybe this recipe is a good place to start!

    1. It is super tasty Michelle and easy to make. I hope you try it.

  6. This looks so fresh and flavorful!

  7. Cooper cracks me up! I think this sounds like it would go pretty well with penne too ;-)

    1. haha I know, me too. Yes it would be good with penne.

  8. I love tomato sauce a lot. So I often make spaghetti with this sauce. It's kinda classic and easy to make also. Sometimes I mix it with beef or bacon, it's always delicious!!.

    My recipe is very simple but yours have more ingredients, I think they would be a plus for the taste 😋 Gonna try it soon!

    1. Great minds think alike Natalie. It is a very tasty sauce.

  9. This looks delicious! We all love roasted vegetables so this would go down very well indeed in our house!

    1. You can't beat the flavour of roasted vegetables. So nice!

  10. Mmmm what a lovely sounding pasta sauce! Love all the M&S varieties too - there's definitely a time and a place for ready made sauces. :)

    1. Thanks Elzabeth and yes there is a great range at M&S, so handy for quick mid-week meals.
