Happy holidays everybody! I don’t know about you, but year after year, even with lots of planning and many lists, I tend to cook WAY too much, leaving my family stuck with the same leftovers to eat for days upon end. Thankfully, my Patchwork Puff Pastry Turkey Pot Pie takes care of two Thanksgiving leftovers: turkey and green beans, reinvented into a delicious and (if I may say so), beautiful comfort food meal. 

The recipe also uses one of my favorite ingredients: frozen puff pastry for the pie crust. In my opinion, this dough is magical, baking up into flaky, buttery layers of goodness and taking dishes from ho-hum to hip-hip-hooray. The best news is that it’s easy to work with if you know a couple of key tricks.

Tips for working with puff pastry dough

If puff pastry intimidates you, not to worry. Here are my tips for baking with puff pastry dough.

1. Thaw, thaw, thaw 

Since the most common brand of puff pastry comes in frozen form, it’ll need to be defrosted prior to baking. I prefer the defrost-in-the-fridge-overnight method. This allows the dough to become workable without allowing the fat to melt. If, however, you forget to thaw overnight, don’t fret. Remove the pastry from the outer and inner package and thaw at room temperature for about 40 minutes, or until it’s pliable. 

Science lesson side-note: Puff pastry is a laminated dough, meaning there are layers upon layers of dough separated by butter (or shortening, in the case of some brands). As the dough bakes, the water in the layers turns into steam, making large air bubbles form. We know that water and fat don’t mix, so when the heat from the steam gets trapped between the layers of dough and butter, it causes the pastry to puff up. Ensuring that the butter is nice and cold prevents it from “melting” into the dough.

2. Flour the surface

Prevent sticky situations by lightly coating your work surface and rolling pin with all-purpose flour.

3. Use a sharp knife or pastry cutter

When cutting puff pastry, you’ll want to be sure to make smooth, clean cuts. Otherwise, the edges can get smashed and compress, preventing them from rising.

4. Don’t overdo it

Rolling the dough too much or re-rolling multiple times causes a build-up of gluten, which could cause the dough to bake up flat.

5. Keep it cold

After I’ve worked with the dough, I refrigerate it until just before baking. Dough that is colder will rise more because it takes longer for the cold butter to melt.

6. Turn up the heat

High heat is crucial to creating that steam in between the layers of puff pastry, so here's an important tip: preheat oven to 400°F (or higher, for some recipes) before you bake for crispy, flaky pastry.

How to make the best leftover turkey pot pie

Now that you know the basics for how to work with puff pastry to create a beautiful topping, let’s turn to how to make a really delicious Thanksgiving leftover pot pie.

In a classic pot pie recipe, the turkey and vegetables are held together with a white sauce, which can be as simple as seasoned milk thickened with a flour-and-butter roux. For maximum flavor I opted for a combination of dry sherry, chicken broth, and milk for the liquid, with sauteed shallot, garlic, black pepper, and and fresh thyme and fresh rosemary for complexity.

As for the veggies, I went with leftover green beans and then added sauteed mushrooms because they’re so terrific with the flavor of sherry. But you could use cooked carrots, cooked or even frozen peas, diced sweet potatoes, or another leftover Thanksgiving vegetable if you like.

And then there’s the turkey. Whether you roasted or grilled the bird this year, cooked it sous vide or in an Instant Pot, the leftover turkey will be outstanding tucked into the pot pie. Out of turkey? You can make the recipe anytime of year with rotisserie chicken for a chicken pot pie!

To make your savory pie, melt butter and then saute the vegetables over medium heat. Add the liquid, including 2 1/2 cups chicken broth (or turkey broth, if you have some on hand) and some flour, and cook briefly until thickened. Stir in the turkey and green beans, then transfer the turkey mixture to a baking dish. Now add squares of puff pastry for a top crust. Then brush them with egg wash for a beautiful shine, and bake until golden brown. Total time here is 2 hours, but a good chunk of that is baking time.
