This is such an easy way to make a flavour-packed roasted vegetable pasta sauce in the oven! The vegetables are roasted first (in my special garlic/herb/spice mix) then we add in our simple sauce ingredients and let them bubble together in the oven. We finish it off with a lovely dollop of crème fraîche, then toss it together with cooked pasta.
I don’t know about you, but I’ve often roasted vegetables, then added them into a pan with other ingredients to ‘turn it into a sauce’.
In my constant bid to reduce the amount of washing up (which seems to be one of my top 5 targets every day), I realised you could just make the sauce in the oven!
Roasting the vegetables gets them just that little bit charred (= more flavour) and then any roasting juices that are released make up part of the sauce too.
It’s only once the vegetables are roasted that we add in a few extras to ensure we get lots of luscious, flavourful sauce.
Unfortunately you do still need one extra pan to cook the pasta, but we can’t win them all 😁

Full recipe with detailed steps in the recipe card at the end of this post.
The vegetables are coated in a flavourful mixture of garlic, olive oil, balsamic vinegar, oregano, paprika and a little salt and pepper before being roasted.
After about 25 minutes in the oven, they should be slightly charred here-and-there, lovely and tender, and should have released some roasting juices in the pan – which will help flavour our sauce.
We add tomato puree (paste in the US) stock and a little Worcester sauce to the the vegetables, and put them back in the oven for a final 10 minutes.
Once it comes out of the oven, I like to thicken the sauce slightly with a little bit of cornflour slurry, then we toss the sauce together with a couple of tablespoons of crème fraîche and plenty of cooked pasta.
👩🍳PRO TIP If you want a smooth sauce to get past the veg-dodgers, blitz up the sauce when it comes out of the oven, then stir in the crème fraîche and pasta.
I love to top with shavings of cheese, a few basil leaves and a sprinkling of black pepper.
🍽️ What to serve it with
- Easy Garlic Bread
- A Simple Green Salad
- If you like a little sweet-heat try drizzling with Sweet Chilli Sauce
As per usual, I get to eat all the mushrooms with this dinner, because no-one else in my family likes them!

Notes
- Swap out some of the vegetables for your favourite vegetables – asparagus, green beans, small cubes of butternut squash or sweet potato all work well (add them in at the same time as the rest of the vegetables).
- Add frozen peas or tinned/frozen sweetcorn (add these in with the stock).
- Stir in wilting leaves such as baby spinach or watercress at the end.
- Swap out the tagliatelle for your favourite pasta – use fresh or dried and cook as per the pack instructions before adding in.
- Double the recipe to serve 8:
- You’ll need a LARGE roasting tray – large enough to ensure you can put the vegetables in a single layer. Double everything EXCEPT the stock. Go with 420ml (1 + 3/4 cups).
- Add 5-10 minutes to the time when roasting the vegetables.
- Add 10 minutes to the time when the stock goes in.
- Halve this recipe to serve two people:
- Halve everything EXCEPT the stock. Use 3/4 of the amount of stock which is 180ml (3/4 cup).
- Use the same timings as with the original recipe.

This was delicious! I didn’t have courgette or mushrooms so swapped it for one large aubergine cut into cubes, also didn’t have creme fraiche so used equal amount of plain Greek yogurt. Lovely flavours and quick and easy to make. I blended some and my fussy eating 6 year old ate it. A winner for us!
Really good recipe to follow and it’s such a tasty dish. I serve with garlic bread and it goes down a treat

Delicious!! My husband loved it as well. Thank you for this recipe!
I just made this recipe today. It was well liked by my family as a Sunday gathering dish. I will be making this again without a doubt.
Tried this with our fresh vegetables and it was delicious!!! no more jar pasta sauces for our table!!!!
Cooked this exactly to the recipe & I can fully say it was amazing best pasta I had in a long time. Will definitely be making this on a weekly basis, well done.
Mmm, it looks so scrummy! Your recipes manage to make me salivate just by reading them and viewing your perfectly vibrant photos ☆☆. If I added a protein what would you suggest including the flavour?
