Slice the tomatoes into halves and the onion into quarters.
Place onto an oven baking tray (tomatoes sliced side facing up). Along with 4 garlic cloves still in their skin (stops them burning when roasted). Drizzle over the olive oil and sprinkle the dried oregano on top along with a couple pinches of salt & pepper. Place in the oven for 1 hour at 160C.
Remove from the oven and scrape the ingredients from the tray into a large pot. Add the 500ml of stock along with the handful of fresh basil leaves (stalks are also fine). Bring to boil and then allow to simmer for 10 minutes.
Now just hand blend until smooth (or transfer to a blender).
