This is such an easy way to create one Spicy noodle sauce made from roasted vegetables in the oven! The veggies are first roasted (in my special garlic/herb/spice blend), then we add our simple sauce ingredients and let them simmer together in the oven. We finish it off with a nice dollop of crème fraîche and then toss it along with cooked pasta.

I don’t know about you, but I’ve often roasted vegetables and then added them to a pan with other ingredients to “make a sauce.”
In my constant attempt to reduce the amount of washing up (which seems to be one of my top 5 goals every day), I realized you could make the sauce in the oven!
Roasting the veggies just chars them a little (= more flavor) and the released gravy then makes up part of the sauce as well.
It is only once the vegetables are roasted that we’re adding a few extras to make sure we get a lot juicy, flavorful sauce.
Unfortunately you need an extra pan to cook the pasta, but we can’t all win 😁

Full recipe with detailed steps in the recipe card on the end of this post.
Before roasting, the vegetables are coated in a flavorful mixture of garlic, olive oil, balsamic vinegar, oregano, paprika and a little salt and pepper.

After about 25 minutes in the oven, they should be lightly charred here and there, nice and tender, and giving off some of the cooking juices in the pan—which helps our sauce flavor them.
We add tomato puree (paste in the US) broth and some Worcestershire sauce to the veggies and put back in the oven for the last 10 minutes.

Once it comes out of the oven, I like to tie the sauce in with some mashed cornmeal, then we toss the sauce along with a few tablespoons of crème fraîche and plenty of cooked pasta.

👩🍳PRO TIP If you want smooth sauce To bypass the veggie refusers, whip the sauce when it comes out of the oven, then stir in the crème fraîche and pasta.
I love to garnish with cheese shavings, a few basil leaves and a sprinkling of black pepper.

As usual, I get to eat all the mushrooms at this dinner because no one else in my family likes them!

✎ Notes
Can I advance it?
Pasta dishes like this are usually best served immediately. However, if you have leftovers, you can cool them immediately, cover and refrigerate. It should keep well in the fridge for up to two days.
Microwave individual servings for 3-4 minutes, stirring a few times during heating. You can add a splash of water, broth, and/or cream to fluff up the noodles, as the noodles will absorb more sauce while reheating.
can i freeze it
No, I do not recommend freezing this dish. This will make the vegetables mushy when thawed.
ingredient swap
- Swap out some veggies for your favorite veggies – asparagus, green beans, small cubes of butternut squash, or sweet potatoes all work well (add at the same time as the rest of the veggies).
- Add to frozen peas or canned/frozen sweetcorn (add these with the broth).
- stir in withered leaves like baby spinach or watercress at the end.
- Swap out the tagliatelle for yours favorite pasta – Use fresh or dried and cook according to package directions before adding.
