Caramelised Onion and Anchovy Spaghetti
You'll love this Caramelised Onion and Anchovy Spaghetti. Slow-cooked onions, butter and anchovies come together to create one of the most ridiculously good pasta sauces for how simple it is. The onions cook down until jammy and sweet, while the anchovies melt in and add this deep savoury richness without tasting fishy.
Ingredients
- 3 large brown onions finely sliced
- 6 anchovy fillets or 2 teaspoon anchovy paste
- 4 garlic cloves finely chopped
- 50 g salted butter
- 2 tablespoon olive oil
- 1 teaspoon brown sugar optional
- sea salt kosher or fine sea salt
- 350 g spaghetti
- ½ cup pasta water reserved
- 50 g parmesan finely grated
- 5 sprigs thyme leaves removed from stems
- ½ lemon juiced
Instructions
- Heat the olive oil in a large pan over medium heat. Add the onions with a big pinch of salt and cook slowly, stirring often, for 10 - 15 minutes until softened. Add the brown sugar and continue cooking for another 15 - 20 minutes, stirring regularly, until deeply golden, jammy and caramelised. If they start catching, add a splash of water and keep going.
- Add the butter, anchovies and garlic and cook for a minute or two, letting the anchovies melt into the onions. Add a generous amount of black pepper.
- Meanwhile, cook the pasta in well-salted water until just shy of al dente. Reserve a cup of pasta water before draining.
- Add the pasta straight into the onion mixture with a splash of pasta water. Toss well so everything emulsifies into a glossy sauce, adding more pasta water as needed. Stir through the parmesan and half of the thyme until melted and silky.
- Finish with a squeeze of lemon juice, extra black pepper, more parmesan and thyme to serve.
