Prepare the pasta in boiling salted water according to the instructions on the packet. Wash, clean and halve the tomatoes. Clean, wash and cut spring onions into thin rings. Drain the pasta and chill in cold water. Mix milk, ricotta and eggs. Season with salt and pepper. Grease a springform pan (26 cm Ø)
Cover the outside of the springform pan firmly with aluminium foil. Layer half of the noodles in the springform pan. Distribute spring onions and cherry tomatoes, up to 6 pieces, on top. Spread the rest of the noodles on top. Add the cherry tomatoes. Pour ricotta-egg mixture over it. Cook in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: see manufacturer) for about 1 1/2 hours. Cover with foil after approx. 1 hour
Wash the basil, shake dry and pluck the leaves from the stalks. Remove the macaroni tart from the oven. Carefully remove from the mould and arrange on a plate. Garnish with Parma ham and basil
