Grab These Ingredients

  • Stuffing: 2 cups give you that crunchy, golden top. Breadcrumbs fill in if you’re short
  • Broth or Butter: Pour on ¼ cup to help the stuffing crisp yet stay moist
  • Milk: ¼ cup thins out the gravy a bit. Use whichever kind you keep around
  • Gravy: 1 cup leftover turkey or chicken gravy to soak everything in flavor
  • Corn: 1 cup for bursts of color and sweetness. Sub in any leftover veggies you like
  • Mashed Potatoes: 2 cups soften it all up and make each bite creamy
  • Cranberry Sauce: Spread on 1 cup for a tangy, sweet punch. Any jam-like spread works too
  • Turkey: 2 cups shredded and ready. Any cooked chicken or poultry swaps in easily

Where the Idea Came From

This dish came alive after staring at boxes of holiday leftovers, just wanting a shortcut. So instead of reheating pieces, everything got tossed together. Put it all in one pan, stick it in the oven, and it’s amazing—way better than the sum of its parts!

Why Everyone's Obsessed

Everyone in our house gets excited for this almost like actual Thanksgiving. All your favorite bites are mixed together in just one pan, start to finish in half an hour. Kids think it’s awesome, you don’t waste food, and leftovers make an unreal lunch next day.

Switch It Up How You Like

Go heavy on the parts you love. Extra potatoes? Go for it. Got a ton of stuffing? Pack on more. Slide in a layer of extra green beans or slip sweet potatoes between everything. Each family does it their way and that’s what makes it fun.

Do Leftovers the Clever Way

Using up what you cooked already cuts down on waste and saves you cash. You stretch the groceries, don’t toss a thing, and get another meal or two before heading back out to shop. It’s good for your pocket and helps the planet too.

Frequently Asked Questions

→ Can I swap in chicken for turkey?

Totally! Pull apart some rotisserie chicken and use it just like you would turkey. You'll still get those great holiday flavors.

→ What if I'm out of cranberry sauce?

Try apple sauce with a splash of lemon, any kind of berry jam, chopped apples and dried cranberries, or even a bit of orange marmalade for sweetness.

→ How do I make it without dairy?

Mashed potatoes are easy with dairy-free milk, gravy works with stock, and lots of stuffings have no dairy—just check the bag. Sub butter with olive oil wherever you need.

→ Is it OK to prep ahead?

Go for it! Put everything together, stick it in the fridge for up to a day, then bake and add just a bit more time. If you want the stuffing fresher, save it for just before baking.

→ How can I make the top crispy?

Take off the cover for the last 10 minutes, throw on buttered breadcrumbs or toss some crushed chips into the stuffing. Drizzle on melted butter to really get that crunch.

→ How long can I keep leftovers?

Pop them in the fridge for 3-4 days, though it's best to eat in the first couple days so things don't get soggy.

→ Is it alright to freeze extra portions?

Absolutely! Wrap it up well and freeze for up to two months. Let it thaw overnight in the fridge before you reheat.

→ What if it dries out?

Just add a bit more broth or gravy and mix it around. Each batch of leftovers holds moisture a little differently.

→ No stuffing left—what else tastes good on top?

Mix it up with cracker crumbs and herbs, mashed potatoes, pieces of cornbread, or a handful of crispy fried onions for the crunch.

Conclusion

Still hungry? Whip up a Turkey Shepherd’s Pie with your leftovers. Layer turkey and gravy first, then spread those mashed potatoes on top. Bake until crisp and dig in for another round of holiday comfort.
