I boil my spaghetti (yes spaghetti ) until done . Drain ,put 1/2 in a 9" X 13 " pan . Add THICK (1/4 " or so thickness ) of sharp cheddar cheese sliced NOT shredded . Add rest of spaghetti & another layer of cheese . Pour milk in pan just until it comes to the 2nd layer of spaghetti . Bake 350 degree 35 -35 minutes . This takes almost 1 box of thin spaghetti & 2 pounds of cheese . Do NOT put in to much milk
