How to Make Turkey and Mashed Potatoes Casserole
Preheat the oven to 400 °F. This warm environment is essential for that lovely bubbly texture you seek when baking the casserole!
Saut onions and garlic in the olive oil over medium-high heat. Cook for about 2 minutes until they re translucent and aromatic, creating a perfect flavor foundation for your casserole.
Incorporate the shredded turkey into the skillet and let it mingle with the onions and garlic for about a minute. Add the leftover gravy and chopped parsley, seasoning with salt and pepper as desired. Let everything combine and heat through.
Adjust the consistency of your mashed potatoes by adding heavy cream if they ve thickened too much in the fridge. This will ensure they spread easily in the casserole.
Spread 1/4 of the mashed potatoes on the bottom of a lightly greased 9 13-inch baking dish. Layer the turkey filling right on top, then finish with the remaining mashed potatoes, creating a fluffy cloud on top!
Sprinkle the freshly grated parmesan cheese generously over the casserole. Bake it in the preheated oven for 30 minutes, or until the top is beautifully bubbly and golden brown. For extra indulgence, top it with more parmesan!
Optional: Garnish with extra chopped parsley before serving for a fresh touch.

Turkey and Mashed Potatoes Casserole Recipe FAQs
What kind of turkey should I use?
Absolutely! Using leftover turkey is ideal for this casserole since it adds flavor and nostalgia. However, if you don t have leftover turkey, you can use rotisserie chicken or even cooked beef. Just shred it into bite-sized pieces to ensure it blends well with the other ingredients.
How should I store leftover Turkey and Mashed Potatoes Casserole?
To keep the delightful flavors intact, store any leftovers in an airtight container in the fridge for up to 3 days. When reheating, I suggest covering it with foil and baking at 350 °F until warmed through to avoid drying it out.
Can I freeze the Turkey and Mashed Potatoes Casserole?
You sure can! To freeze, let the casserole cool completely, then wrap it tightly in plastic wrap and aluminum foil or place it in an airtight freezer-safe dish. It can be frozen for up to 2 months. When you re ready to enjoy it again, thaw it overnight in the fridge, then reheat in the oven for the best results!
What should I do if my mashed potatoes are too thick?
Very simple! If your mashed potatoes have thickened too much, just add in about 1/2 cup of heavy cream and mix thoroughly until you achieve that creamy, spreadable consistency. You can also warm them slightly before mixing, which can make this process even easier.
Is this casserole suitable for people with dietary restrictions?
Great question! This Turkey and Mashed Potatoes Casserole can be modified for various dietary needs. If someone has a gluten allergy, make sure your gravy is gluten-free. For dairy-free options, substitute the heavy cream and parmesan with your favorite dairy alternatives, like almond milk and nutritional yeast. Just remember to double-check labels for allergens, especially if you re serving this dish to guests.
How can I prevent the casserole from becoming too dry when reheating?
To maintain moisture, it s best to reheat the casserole in the oven at 350 °F and cover it with foil for the first part of heating. This will create steam and help keep it moist. Check its progress, and remove the foil towards the end to allow the top to crisp up nicely!
