Ingredients

Stuffed Shells:
24 jumbo shells, about 1/2 pound
1 tablespoons olive oil
1/2 cup finely chopped onion
2 teaspoons minced garlic
1 1/2 pounds ground veal
1/2 pound ground pork
2 teaspoons finely chopped marjoram leaves
1 1/2 teaspoons kosher salt
3/4 teaspoon ground black pepper
1/4 cup heavy cream
1 large egg

Mushroom Bechamel:

4 tablespoons unsalted butter
1 pound button mushrooms, cleaned and thinly sliced
1 teaspoon fresh thyme leaves
1/2 cup small diced onion
2 teaspoons minced garlic
4 tablespoons all-purpose flour
3 cups whole milk
1/2 teaspoon salt
1/4 teaspoon fresh ground white pepper
1/8 teaspoon fresh grated nutmeg
Freshly grated Parmesan

Directions

Set a large, 4 to 6-quart stockpot filled with water over
high heat and bring to a boil. Season with salt and add the dried shells to the pot. Cook the pasta until
pliable but not al dente, about 8 minutes. Remove the shells from the water and lay out on a sheet pan to
cool. Be sure to lay each shell directly on the sheet pan without touching any of the other shells so that
they will not stick.

While the shells cool, make the shell stuffing. Set an 8-inch saute pan over medium heat and add the olive oil
to the pan. Once the oil is hot, add the onions and garlic to the pan. Cook until the onions until softened,
about 3 minutes. Remove from the heat and set aside to cool. In a medium bowl, combine the ground veal, pork,

marjoram, kosher salt, black pepper and the cooled onions. In a separate, smaller bowl, combine the cream and
egg and whisk to combine. Add the cream and egg mixture to the veal mixture and mix until thoroughly blended
without over-mixing.

When the shells have completely cooled, place 2 tablespoons of the stuffing into each of the 24 shells, and
place the open-end down in a 9 by 13 by 2-inch casserole dish. When completed, wrap the casserole with plastic
wrap and set aside in the refrigerator as you prepare the bechamel.

Preheat the oven to 350 degrees F.

Set a 1-quart saucepan over medium-high heat and add the butter. Once melted, add the mushrooms and thyme
leaves to the pan and cook, stirring often, until most of the liquid has evaporated, about 5 minutes. Add the
onions and garlic to the pan and cook for 3 to 4 minutes, stirring occasionally. Sprinkle the flour into the
pan, stir to combine, and cook the roux, stirring, for 2 minutes. Whisk the milk into the saucepan. Season the
bechamel with the salt, pepper and nutmeg and stir to combine. Bring the bechamel to a boil, reduce the heat
to a simmer, and cook, stirring frequently with a wooden spoon, until sauce is thick and smooth and any floury
taste is gone, about 5 minutes.

Remove the shells from the refrigerator, discard the plastic wrap, and pour the bechamel over top the shells.

Sprinkle the parmesan cheese over all and place the casserole in the oven. Bake the shells until the bechamel
is bubbling and the top is golden brown, about 30 minutes. Be sure to rotate the casserole after 15 minutes to
ensure even browning. Remove from the oven and allow to rest of 5 to 10 minutes before serving.
