So, I’m sure you are all on tenterhooks, waiting to see what I made. I decided to try tetrazzini. Then I looked up some recipes, and they were all different. So I cobbled something together, relying heavily on what I happened to have at hand in my quarantine kitchen. Most of the recipes called for mushrooms, and I can see how that would be better, but my husband hates mushrooms, and I don’t have any, so those got left out. Otherwise, it’s pretty similar to recipes I found.
Preheat oven to 400F
Boil up 1/2 pound egg noodles and when they were done, I added maybe 1/4 pound leftover cooked egg noodles from the fridge.
In a separate le creuset casserole dish, I melted 2 Tbsp butter, and sauted a chopped white onion.
When it was soft, I added a minced clove of garlic, and a tablespoon or two of fresh thyme leaves, since my thyme garden is over-growing its boundaries. (It’s gotten all through the lawn. Anyway, I have a lot of it.)
Saute briefly, and then toss atop the cooked noodles.
In the same pan, melt another 4 Tbsp butter, and slowly add a scoop of flour (between 1/4 and 1/2 cup) stirring well. After it was incorporated, I tossed in a two cup block of frozen duck broth.
That took longer than I hoped to melt, and I didn’t want my roux to burn, so I added some ancient marsala that I found in the back of the liquor cabinet a couple of weeks ago, along with a dollop of past-its-prime blush wine a friend made, that’s been sitting in the fridge. Stir, cover, and cook until the broth all melted.
Stir it some more to remove the new lumps, and then I added 1.5 cups of sour cream leftover from making birthday cake.
Stir well.
Then add the pasta & veggies, along with the cubed duck (I ended up not using all of it, because there was a lot – maybe 2 cups of duck meat) salt, pepper, about 2 cups of supermarket shredded mozzarella and stir well.
Sprinkle the top with about 1/4 cup of freshly grated parmesan cheese.
Put in the hot over, uncovered. Cook 20-25 minutes, as I type up this post and until the noodles on top brown a little. Remove from the oven (just did that) and let sit 10 more minutes.
Serve. Wish me luck. 
(the sauce that I licked off the spatula tasted pretty good.)
