Heat the oven to 180C/160C fan/gas 4. Put the Boursin in a roasting tin and tip in the tomatoes, red onion and thyme. Cook for 10 mins then add in the frozen spinach and cook for 15 mins more or until the Boursin is soft and the spinach has melted.

While the Boursin is cooking, cook the pasta to pack instructions (around 10-12 mins). Remove a mug of the pasta water before draining then drain the pasta and set aside.

Pour a few tablespoons of the pasta water into the roasting tin and mix everything together. The tomatoes will begin to fall apart and the water should help create a cheesy sauce. Combine the sauce and pasta in the tray or in the pasta saucepan along with the parmesan. Divide between 4 pasta bowls or plates and serve.
