While you make your cheese sauce, pop the spaghetti into salted boiling water and cook until al dente (so it still has a little bite to it – not completely soft).
To make the cheese sauce combine the Nestle dessert and cooking cream and milk and heat gently in a small pot. Then melt the butter in a separate pot and add the flour and whisk. Then slowly add the cream and milk mixture while whisking like crazy until smooth. Simmer for 5 minutes until thickened. Lastly add 1 cup of mature cheddar cheese and seasoning.
At this point preheat the oven to 200’c. Grease a medium baking dish or individual portion dishes (like I did). Empty the spaghetti into the Bolognese and mix together. Pour the spaghetti Bolognese into the baking dish, top with creamy cheese sauce, extra grated cheese on top and bake for 15 minutes. Remove from th oven once the cheese is golden and enjoy.
