Bucatini with Butter-Roasted Tomato Sauce

This roasted tomato bucatini is a revelation in simple, high-protein cooking. By roasting tinned tomatoes with plenty of garlic, butter, and savoury anchovies, you create a complex, jammy sauce that tastes as though it has simmered on the hob for hours. The oven does all the hard work here, caramelising the natural sugars in the tomatoes while the garlic softens into a mellow, buttery paste. It is a sophisticated yet low-maintenance dish that elevates store-cupboard staples into something truly special.

Ideal for a comforting midweek meal or an easy weekend dinner, this recipe relies on the emulsion of melted butter and starchy pasta water to create a silky coating. While bucatini is the traditional choice for its satisfying chew, spaghetti or linguine work equally well. Serve this vibrant pasta with a generous dusting of Parmesan and a pinch of dried chilli for a subtle, warming heat.

Ingredients for Bucatini with Butter-Roasted Tomato Sauce

  • 1 (800g) can whole peeled tomatoes

  • 8 garlic cloves, peeled, crushed

  • 2 anchovy fillets packed in oil

  • 60ml (1/2 stick) unsalted butter, cut into small pieces

  • 1/2 teaspoons crushed red pepper flakes plus more for serving

  • Kosher salt, freshly ground pepper

  • 350g bucatini or spaghetti

  • Finely grated Parmesan (for serving)

Preheat oven to 218°C. Combine tomatoes (crushing them with your hands), garlic, anchovies, butter, and 1/2 teaspoons red pepper flakes in a 13x9" baking dish; season with salt and black pepper. Roast, tossing halfway through, until garlic is very soft and mixture is jammy, 35–40 minutes. Using a potato masher or fork, mash to break up garlic and tomatoes.

Meanwhile, cook pasta in a large pot of boiling salted water, stirring occasionally, until al dente. Drain, reserving 120ml pasta cooking liquid.

Return pasta to pot and add tomato sauce and pasta cooking liquid. Cook over medium-high heat, tossing until sauce coats pasta, about 3 minutes. Serve topped with Parmesan and more red pepper flakes.

Tomato sauce can be made 4 days ahead. Let cool; cover and chill. Reheat before mixing with pasta.

You may never stir again once you've given this low-maintenance tomato sauce a try. Roasting coaxes depth from canned tomatoes, instilling a long-cooked flavour. A generous amount of garlic and anchovies adds even more character. Here are other ways to use the wonderful sauce beyond pasta:

Tomato Soup: Purée with vegetable or chicken stock and a splash of cream for a warming bowl.

Omelette: Fold a spoonful inside an omelette along with pieces of smoked mozzarella.

Pizza: It is tomato sauce, after all. Spread it on pizza dough and shower with Parmesan. Bake and top with more anchovies, parsley, and lemon zest.
