Delicious Leftover Turkey Puff Pastry Pie with Mashed Potatoes, Broccoli, and Cheese Sauce is easy to make and the perfect way to reinvent Thanksgiving leftovers!

The weekend after Thanksgiving is always pretty hectic around here.

On Friday we put up the Christmas decorations, which involves getting them out of storage, sifting through them as we reminisce, and arranging them just-so.

(My mom is the one who makes sure they’re arranged “properly”. She likes to let us all think we’re helping, but as soon as we leave the room she’ll rearrange something if it wasn’t laid out exactly as she likes it laid out. It’s pretty hilarious when we catch her in the act!)

We usually try to whip up a batch or two of our favorite Christmas cookies, and watch one of our favorite holiday specials on TV. And if there’s time (or a bargain that’s just too good to pass up), we’ll brave the mall.

Between all that, there really isn’t much time for cooking. It’s a good thing there are always tons of leftovers from Thanksgiving, but there are only so many nights in a row that I can eat the same turkey dinner. This meal is a fun one to switch things up while still making use of leftovers!

The Best Turkey Puff Pastry Pie Recipe

Here’s what you’re going to LOVE about this recipe:

  • It completely reinvents Thanksgiving leftovers into a whole new dinner. With broccoli, cheese sauce, and flaky, golden puff pastry you won’t even realize you’re eating leftover Thanksgiving dinner!
  • Cheese sauce, yuuum. It only takes about 10 minutes to make, but it adds so much flavor to this dish. And who doesn’t love cheesy goodness, right?!
  • It’s a full meal in one dish. One of the things I love most about casseroles is that they’re a full meal with all the parts in one. Here the meal is completed with leftover turkey for protein, and broccoli for a vegetable.
  • Golden, flaky puff pastry. There’s just something about a flaky crust. It’s buttery and delicious, and also provides great texture for this Thanksgiving leftovers casserole. It’s perfect comfort food!

How to Make Puff Pastry Pie with Thanksgiving Leftovers

  1. Make the cheese sauce. Add the butter to a medium saucepan over medium heat. Stir in the onion and cook until softened, but not browned, about 5 minutes, stirring occasionally. Add the garlic and cook 1 minute more, stirring constantly. Add the flour and cook 1 minute. Whisk in the milk, Dijon, Worcestershire, paprika, salt, and pepper, and bring to a simmer, whisking frequently. Turn off the heat and whisk in the cheese a handful at a time until smooth.
  2. Assemble the casserole. Spread the mashed potatoes in the bottom of the prepared dish. Spread the chopped turkey evenly on top of the mashed potatoes, and then spread the broccoli evenly on top of the turkey. Top with the cheese sauce, and spread it out evenly as best you can. Let the casserole cool slightly (this is so that the puff pastry isn’t going on top of hot sauce, which may cause it to not rise properly). Unwrap the thawed puff pastry and place it on top of the casserole, tucking the sides down into the dish. Brush a little eggwash on top (there will be extra – do not try to use it all), and cut a few slits in the top of the puff pastry for the steam to vent.
  3. Bake the casserole. Bake this turkey puff pastry pie until the pastry is puffed and golden, about 25 to 30 minutes. Cool slightly before cutting and serving.

How to Freeze Turkey Puff Pastry Pie

  1. Assemble the casserole, but don’t put the puff pastry on top.
  2. Let the casserole cool to room temperature.
  3. Wrap the entire casserole well with plastic wrap.
  4. Freeze it for up to 3 months.
  5. The night before you want to make this turkey puff pastry pie, put it in the fridge to thaw overnight along with a sheet of puff pastry.
  6. When you want to bake it, put the puff pastry on top of the thawed casserole and bake as directed.

Variations on This Recipe

  • No turkey, no problem. If it’s not just after Thanksgiving and you don’t have a ton of turkey in your fridge, no worries! You can also use leftover chicken or rotisserie chicken to make this.
  • Swap out the broccoli. I’ve also made this casserole with steamed cauliflower instead of broccoli and it’s every bit as good.
  • Use your favorite cheese. Instead of cheddar, you can use anything you like! Try Gouda, Colby, Edam, or Swiss.

Tips for Making Leftover Turkey Puff Pastry Pie

  • You don’t want soupy mashed potatoes. Then your finished casserole won’t have any structure. If you’re using leftover mashed potatoes, they should stiffen and dry out in the fridge. They should be a bit dry. However, if your leftover mashed potatoes look too dry and crumbly, you can stir in a splash of milk.
  • Make sure your broccoli is crisp-tender. Don’t use raw broccoli (it won’t soften enough while the casserole is in the oven).
  • The cheese sauce will be thick. That’s exactly how we want it! We want the cheese sauce to add flavor, not make the casserole soupy.

Instructions
 

  • Preheat oven to 400F; grease an 8 by 8-inch casserole dish with butter.

Faith’s Tips

  • Mashed Potatoes: Taste the leftover mashed potatoes and add salt and pepper as necessary. They should be dry, but if they’re very dry and crumbly, stir in a little milk (don’t add too much though – they should not be soupy!). Or if you don’t have leftover mashed potatoes, you can buy mashed potatoes at the grocery store.
  • If You Don’t Have Leftover Broccoli: You will need 1 pound of raw broccoli (about 4 cups of chopped broccoli florets). Cook it to crisp-tender. To do so, bring a medium saucepan of water to a rolling boil. Season the water with salt, add the broccoli, and cook until crisp-tender, about 1 1/2 to 2 minutes. Drain the broccoli and set aside to cool.

    Don’t tell the Thanksgiving authorities, but I tend to enjoy the re-purposed Thanksgiving leftovers more than the actual feast itself. There’s just so much you can do with all those food items – enter: puff pastry pie. How genius is this thing??? I love the way you think, m’dear!
