This chicken, leek, and sweetcorn lasagne is a delicious twist on the classic Italian dish. The chicken is cooked until tender and then combined with leeks, sweetcorn, and a creamy sauce. The lasagne sheets are layered with the chicken mixture and a cheesy white sauce, and then baked until golden and bubbly. The combination of flavors and textures in this lasagne is truly satisfying. Serve it as a main course for a comforting family dinner.
