Turn your holiday leftovers into pure comfort with this cozy, golden-topped leftover turkey casserole that’ll have everyone coming back for seconds. Each bite layers tender turkey, savory gravy, buttery mashed potatoes, sweet corn, and herbed stuffing for the ultimate post-feast flavor.
I am so excited to partner with Bob Evans to create this fall favorite recipe!

Holly’s Cozy Casserole Highlights
- Flavor: Rich, savory, and comforting; all your favorite holiday flavors in every bite!
- Time-Saving Tip: No leftovers? Ready-made mashed potatoes and stuffing make this dish a breeze.
- Freezing: Portion and freeze for up to 3 months, then thaw overnight and reheat for a quick, comforting meal anytime.

Ingredients for Comfort in a Casserole
- Turkey: Cut leftover turkey into cubes or shred it. Chicken, Cornish hen, ham, and even ground Italian sausage make a delicious casserole!
- Veggies: Fresh or leftover green beans, corn, broccoli, peas, mushrooms, or even a frozen bag of mixed vegetables can be used. No gravy? Use a can of mushroom soup!
- Potatoes: Use leftover or ready-made mashed potatoes. Even leftover mashed sweet potatoes will work if you have them, or why not mix them both?

How to Make Turkey Casserole
- Sauté celery, onion, and seasonings in butter.
- Combine the onion mixture with turkey, vegetables, and gravy in a casserole dish.
- Spread mashed potatoes over the turkey mixture and top with stuffing.
- Drizzle with butter and bake (full recipe below).

Savor Now, Store for Later
- Serve leftover turkey casserole with candied carrots, roasted butternut squash, green bean casserole, or bacon-wrapped brussels sprouts for another festive feast.
- Keep leftover turkey casserole in a covered container in the refrigerator for up to 3 days or freeze portions in air-tight containers in the freezer for up to 3 months.
- To freeze, bake the casserole in a foil-lined dish, let it cool completely, then fold the foil over and freeze. Thaw overnight in the fridge before reheating in the oven.

I haven’t but I think that would be delicious Krista! Let us know if you try it!
If I’m going to make this ahead, freeze it and then cook and serve it at a later date, do I fully bake it before freezing or prepare the dish up to baking it and then, bake it once it is thawed?
Hi Amy, We have not tried freezing this casserole but I would prepare it up to baking and then freeze. Since basically everything is pre-cooked you are basically just heating through and browning in the final step. Let us know how it turns out!
