Tuna arrabbiata pasta gratin
This wholesome and filling pasta bake makes the perfect winter comfort food.
Cook the pasta in a large pan of salted boiling water following pack instructions until al dente.
Meanwhile, make the gremolata. In a food processor (or by hand), finely chop the garlic with the zest, parsley (include the stalks) and rocket. Season generously, add the oil and lemon juice, and mix to make a juicy paste. Set aside.
Melt the knob of butter with a small splash of oil in a frying pan, add the prawns and fry quickly on each side. Add the chilli flakes and cook for 1 min or so more until the prawns are cooked.
Drain the pasta and return to the pan. Add the gremolata and the chilli prawns, toss well to coat and check the seasoning. Divide
