Cook and drain the bow tie pasta. Make sure after you cook it and drain it you run cold water over it so it won't cook the eggs when they are added.
Find a casserole pan and grease it, either with spray or butter. Start to layer the ingredients. Put a layer of pasta first, then sprinkle 1.5 to 2 cups of the cheese over it. They cut pads of butter and set them on top of the cheese. I usually put about 5 pads about 1/4 an inch thick each. Then start the layers again; pasta first, then the rest of the cheese. Another 5 pads of butter
Finally, mix the salt, milk, and eggs together and pour them evenly over your layers. Now, preheat the oven to 375 degrees and cook it for 20-25 minutes or until golden brown on top. Mix it good and then sprinkle the bacon on top, cook another 5 min
