The only kinds of pot-pie I think I ever had as a kid were the frozen ones from the grocery store. I can understand why my mom would opt for this. From scratch, a pot-pie can be a lot of work. The frozen ones cook up pretty quick in the microwave. I confess, those frozen ones are still guilty pleasures for me, from time to time.
As I started doing more vegetarian cooking, I became intrigued by the idea of a vegetarian version of the pot-pie. How would we create the savory flavors and stew-like filling I wanted, without meat? This recipe, modified from the America's Test Kitchen recipe, hits the mark pretty well. It's got surprising savoriness, and was easier to make than I thought it would be.
The original version of this recipe only used a top crust. I like crust on top and bottom of my pot pie, thank you, so that was the first change. I'm also a bit lazy. They make their own pie crust. I can do it, but I don't like to so, I used store bought crusts. Not as good as homemade, but I'd rather have pie than not. I prefer the rolled up dough, where you just thaw and unroll it over a pie plate. The only kind I've been able to find at my local grocery store, recently, is the kind that's already in a foil plate. You either use what you've got, or you go home so, I used those this time around. They come with two crusts per package, so I needed to thaw them and remove one of them from the pie plate for the top crust. You're more than welcome to make your own pie crust, though.
9 1/2-inch pie pan (depending on your pie dough source)
measuring cups and spoons
Dutch oven or other large sauce pan with lid
rimmed baking sheet
2 frozen pie-crust doughs
4 Tbl butter
1 onion, finely chopped
8 oz. cremini mushrooms, trimmed and sliced
salt and pepper
1 medium sweet potato, peeled and cut into 1/2-inch pieces
1 medium turnip, peeled and cut into 1/2-inch pieces
3 cloves garlic, minced
1/2 tsp grated lemon zest
1 Tbl lemon juice
8 oz. Swiss chard, stemmed and cut into 1-inch pieces
2 Tbl all-purpose flour
2 cups vegetable broth
1/2 cup grated Parmesan cheese
1 Tbl dried parsley
1 large egg
1 tsp water
Thaw the pie crusts (unless you're using fresh). For the top crust, roll one dough smooth between two pieces of parchment paper. Put it in the refrigerator until needed. For the bottom crust, if using loose dough, gently center one in a 10-inch pie plate, leaving about a 1-inch overhang. If not, just leave it in the provided pan. If there are any cracks, smooth them together with a drop of water and your fingers. Lightly spray the bottom pie crust with cooking spray. (My mom says this helps keep the bottom dough from getting soggy.) Refrigerate until needed.
Adjust the oven rack to the middle position and pre-heat the oven to 400 degrees F.
Melt 2 Tbl butter in a Dutch over or other large saucepan over medium heat until the foaming stops. Stir in the onion, mushrooms and 1/2 tsp salt. Cook until the mushrooms release their liquid, about 5 minutes.
Stir in the sweet potato and the turnip. Reduce heat to medium-low, cover, and cook until potato and turnip begin to soften, about 8 minutes. Stir in the garlic, lemon zest, and parsley and cook until fragrant, about 30 seconds. Stir in the chard and cook until wilted, about 2 minutes more. Transfer everything to a bowl and set aside.
Now to make the roux. Melt the remaining butter in the empty pot over medium-high heat, until it stops foaming. Stir in the flour and cook for one minute. Gradually whisk in the broth, scraping up any browned bits from the bottom of the pan. Bring to a simmer and cook until it starts to thicken, about 1 to 2 minutes. Off the heat, whisk in the Parmesan, lemon juice, and 1/2 tsp salt. Stir in the reserved vegetables, along with any juice that's accumulated in the bottom of the bowl. Season with salt and pepper to taste.
Line a rimmed baking sheet with aluminum foil and place the prepared bottom pie crust/plate in the center. This will help keep your oven clean in case the filling boils-over, ease clean up, and makes it easier to put the pie in the oven if you happen to be using a foil pie plate. Transfer the vegetable mixture into the bottom crust of the pie, and smooth the top. Place the top crust on top. Fold up the bottom edge of the dough around the top dough, and crimp together. Cut four 2-inch slits in the top, with a paring knife, to vent the steam. Lightly beat egg and water in bowl, and brush over the top of the crust. Put the whole thing into the oven. Bake until the crust is golden brown and the filling is bubbling, about 30 minutes. Remove and let cool, on the baking sheet for 10 minutes or so before serving.
