This was delicious. So delicious, in fact, that I finished the half a pan left from dinner around 12 or 1 in the morning. I couldn't help myself, I just kept going back and nuking three at a time, over and over, until they were all gone. The cheese and bechamel are just great together. I've been trying to eat vegetarian at least once or twice a week for health reasons, but I'm not sure if this should count. Fat is flavor and this has plenty of it.
This is a relatively quick recipe to prep and get in the oven, but then you have to wait for it to bake. It was torture. I was starving and kept peaking under the foil to see if the middle was bubbling. Good thing it was worth the wait, I just wish I'd saved a few.
I think the freshly ground nutmeg in the bechamel is very important. The ground nutmeg from a jar just doesn't have the same flavor, especially since many people only use it when they make pies a few times a year. The longer ground spices sit in the jar, the less flavor they have because the essential oils evaporate over time. If you buy whole spices, and grind or grate them yourself, they maintain the oils much longer. Buying whole spices is also MUCH cheaper, especially if you know where to look. I bought a packet of 20 whole nutmeg seeds for $4 at an Indian spice store in Rochester. It would be at least 3 times that amount at my local supermarket.
Mushroom Stuffed Shells with Bechamel
Total Time: approx. 1 1/2 hours
A good amount of your favorite pasta sauce (I used some homemade tomato-basil I had in the freezer)
12 oz. box of jumbo pasta shells
1 medium onion
24 oz. mushrooms of your choice (I recommend button or cremini), chopped roughly to fit in the shells
4 cloves of garlic
Fresh mozzarella
Freshly grated Parmesan
A few lugs of extra virgin olive oil
2 Tablespoons unsalted butter
For the Bechamel:
4 Tablespoons unsalted butter
4 Tablespoons flour
2 1/2 cups milk (whole milk works best, you need some fat)
Kosher salt and freshly ground black pepper
Freshly grated nutmeg
Preheat oven to 350 degrees
Cook the shells according to the box directions but make sure not to overcook. They should be al dente (or even a little less) and will continue cooking in the oven. When they are finished, run cold water over them to stop the cooking. This also makes them easier to handle when you are stuffing them.
While the shells are cooking, saute the onion and garlic in olive oil until softened. Throw in the chopped mushrooms with the 2 tablespoons of butter and cook until softened. You want them to maintain a little texture so your shells have a little bite. When they are where you want them, add half your pasta sauce. I'm not sure exactly how much sauce I used total (I had a large Tupperware full and used all of it).
Make the bechamel by melting the butter in a pan. Sprinkle in the flour and whisk constantly over medium-low heat until browned slightly, this will make sure the raw flour taste cooks out. Whisk in the milk and turn the heat up a little. Keep whisking until the bechamel thickens. Pull off the heat and season with salt, pepper and nutmeg. Make sure you taste the sauce after seasoning and adjust if necessary.
Add a thin layer of pasta sauce to the bottom of a 13 x 9 baking dish. Stuff each shell with about a tablespoon of the mushroom-sauce mixture and some grated mozzarella and Parmesan. Place seam side up in the pan and add the bechamel on top of each. I didn't use all of the bechamel, but I should have. What could it hurt? It is delicious. It may look like a lot, but trust me. Finally, add the remaining pasta sauce over the top of the bechamel.
Cover the pan with tinfoil and bake for about 30 minutes. Uncover and let it go for another 10 or so minutes until it browns slightly on top. Plate a few but allow to cool slightly before digging in, they are very hot!
