Easy Turkey Potato-Topped Casserole

Total Time
Prep 25 mins

This is a basic simple recipe that requires no baking, just simmer ingredients, mix, then put under broiler for 2 minutes, but if you just feel better about baking it...then go ahead and bake it for 8-10 minutes, but it really is not necessary to bake it. It's a great way to use up any leftover turkey (or chicken also!). All ingredients may be adjusted to taste, double the recipe to bake in a 13 x 9-inch pan.

Ingredients Nutrition


  1. Drain and mash the potatoes with 1/2 cup half and half or milk, 3 tbsp butter and salt and pepper (can add in a few tablespoons grated Parmesan cheese or 1/3 cup grated cheddar cheese if desired to the mashed potatoes to kick them up a notch!).
  2. Meanwhile, in a heavy bottom saucepan, melt remaining butter over medium heat.
  3. Cook the onion and garlic in 1/4 cup butter until softened (about 5 minutes).
  4. Add in flour; cook, stirring 1 minute.
  5. Gradually whisk in 2 cups half and half cream, salt and pepper, mustard, lemon juice and thyme; cook, whisking often (about 10 minutes) or until thickened.
  6. Add cubed cooked turkey and veggies; cook 5 minutes, or until veggies are tender.
  7. Pour into a greased 8-inch square baking dish.
  8. Spread potatoes over top; sprinkle with Parmesan cheese.
  9. Broil for 2 minutes, or until golden brown.

Sounded like a good way of using leftover turkey,but we thought it really lacked in flavor.

What a wonderful, filling meal...and perfect on a cold wintery night! This was easy to prepare, using leftover turkey from Thanksgiving. The only thing I did different was to omit the garlic, as I discovered mine were moldy!! Thanks for sharing this recipe, Kitten...both DH and I loved it!

This is a quick & easy one-dish weeknight dinner as well as a delicious way to use up turkey AND leftover mashed potatoes! I scaled the quantities in half, using a combo of frozen peas & corn which I turned into a 6-inch ovenproof dish. Since my potatoes weren't hot, I baked the casserole at 350 for 15 minutes. Thanx for another good one Carol!
