Set out an 9x9 or 10x 7 baking dish ( I prefer ceramic to metal or glass)
Preheat oven to 375 Deg F (190 c)
Cook pasta in salted boiling water according to package directions until just barely al dente, drain and place in a large bowl (once water is boiling about 9 min)
1 pound pasta - large macaroni or other tube noodle such as cavatappi, Salt for pasta water
Add a tablespoon or so of butter in a sauté pan or small cast iron pan over medium heat. Once the butter is foamy add the sage leaves and fry for 30 seconds a side, transfer to a paper towel lined plate to cool. Chop half the leaves into pieces, set aside the whole leaves for garnish.
1 ounce fresh sage leaves plus a tablespoon or so butter to fry
In a medium sauce pan over medium heat, melt the butter. Add the flour and whisk until a thick paste forms then keep cooking while whisking for another 2-3 minutes.
85 g unsalted butter, 85 g all purpose flour
Slowly add the milk a little at a time, whisking constantly keeping the mixture thick. Keep adding the milk a little at a time. and once all the milk is added whisk until it’s the consistency of pudding. About 7 min. Whisk in the grated nutmeg.

1 Tablespoon butter, 120 g panko breadcrumbs, 60 g freshly shredded parmesan, ½ Teaspoon each kosher salt and pepper
Bake for 25-30 min or until the top is golden brown and pasta is bubbly. If the top is browning too quickly, cover the pan with foil, if not golden on top by 30 min has passed, set the oven to broil for one to two minutes. Remove from the oven and garnish with the remaining whole fried sage leaves.
