A home-style, family-favourite casserole was never this easy! Use leftover turkey and store-bought biscuits, canned condensed soup, and frozen veggies to prepare this hearty Leftover Turkey Casserole with Biscuits the whole family will love!

In addition to satisfying, Dear Reader, Leftover Turkey Casserole with Biscuits is also going to give you a well-deserved break from the kitchen. Let’s face it, most of us usually have leftover turkey right after our annual Thanksgiving or Christmas family and friend dinner extravaganzas. And, the cooks (you and me!) are usually exhausted.
As much as I love to complain about the fact that I hate a fridge full of leftovers, I do love to see leftover turkey. There are just so many things you can do with it, making a brand-new meal in the process. Everyone loves Leftover Turkey Soup, but I’m not always in the mood for soup. That is exactly why I came up with this Turkey and Stuffing Tortilla Pizza! I’m never not in the mood for pizza! This is a great option for Thanksgiving leftovers!
I think the most common go-to leftover turkey recipe is the sandwich. You can use it in a wrap, or between two slices of sandwich bread, but why settle for mediocre when you can have fabulous? I made this Bacon and Turkey Panini and I’ve not been able to settle for a regular turkey sandwich since! Oh, and this Crack Turkey Salad is so good it’s hard to say no!

INGREDIENTS NEEDED TO MAKE THIS RECIPE
The following is a list of the ingredients needed to prepare this recipe. For exact amounts and measurements, refer to the printable recipe card located near the bottom of this post.
- Leftover or Cooked Turkey – You will need two cups of diced turkey. I used all white meat, because that’s usually what’s leftover in our home, since we go for the dark meat first. You can certainly use dark meat too. Or, dice up a cold rotisserie chicken if you don’t have turkey on hand!
- Cream of Mushroom Soup – This condensed soup will add flavour and creaminess to the dish.
- Frozen Vegetables – Use your favourite brand with whatever variety you prefer.
- Pillsbury Biscuits – You can find these in the cooler section of your local grocer.
- Milk – To make the casserole creamy, you will want to use whole milk.
- Seasonings – Garlic powder, onion powder, salt, ground black pepper, dried thyme, and dried chives.
- Egg – You will only use the yolk. Whisk it with water to brush the tops of the biscuits with.
- Parsley – For garnish.
THE LEFTOVER TURKEY DILEMMA
That’s why this Leftover Turkey Casserole with Biscuits is going to save the day. Your kids, your spouse, your roommate, your friends, your family, etc., they all need to eat again the very next day.
And, even though you just finished cooking a dinner fit for the Queen herself, you’re expected to get your ass back into the kitchen and whip up something else to fill their now empty stomachs. You don’t need to be ‘the mom’ to be in this predicament. You just need to be the one who does the cooking. In our home, that’s me.
I put this recipe together for two reasons. The first is obvious – I needed to use up the leftover turkey. This past Christmas, I did something that I had never done before in my lifetime. I cooked an entire turkey!

COOK A WHOLE TURKEY AND GET SEVERAL MEALS!
My little family consists of my partner, John.e, and my daughter, McKenna. They are both vegetarians. So, why the heck did I cook an entire 18 pound turkey? There are two reasons for that as well! First, I wanted to try my hand at roasting a whole bird. And, second, Christmas morning is just not the same without the smell of turkey baking in the oven. In previous years, I have always purchased a leg or a thigh, but this year, I wanted to go big!
The second reason this recipe came together was, because even though I had prepared every single meal and snack eaten in our home (even with company coming!) from December 24 until December 31, and I was tired of it. I was hungry too!
So, while John.e and McKenna dined on a hash made from the sides and gravy, I dined on this lovely Leftover Turkey Casserole with Biscuits! Oh, I didn’t eat the whole thing! I wasn’t that hungry!! As usual, I shared this dish with our favourite neighbours.

HOW TO MAKE LEFTOVER TURKEY CASSEROLE WITH BISCUITS:
If you read the list of ingredients above, you will note that we are using a lot of already prepared ingredients in this recipe. There’s absolutely nothing wrong with that! Think about how good this casserole will be after a long day at work, or on a cold evening after being outside all day. It’s going to be well worth the wait, but the good news is that you can do it all in less than one hour!
Start by preheating your oven to 350 degrees F. Next, lightly grease a casserole dish with non-stick cooking spray. You will need a dish that is equivalent to a 9 x 13 inch pan. Set that aside and grab a large bowl. Add the condensed cream of mushroom soup, whole milk, garlic powder, onion powder, salt, ground black pepper, and dried thyme to the bowl. Whisk to combine.
Add the thawed veggies and the diced turkey. Use a rubber spatula to fold everything together, being careful not to break up the turkey too much. Pour the contents of the bowl into the prepared casserole dish. Cover with foil and bake for 30 minutes. Next, remove from the oven and discard the foil.
Open the biscuits and line them up onto the casserole. Brush the tops of each biscuit with the egg yolk and water mixture. Sprinkle dried chives on top. Return the casserole to the oven, uncovered, and bake for 15 minutes. Finally, remove from oven, garnish with fresh parsley and serve immediately.

NO TURKEY? USE CHICKEN!
Leftover Turkey Casserole with Biscuits is a very flexible recipe. If you don’t have any leftover turkey, you can most certainly use chicken. And the vegetables that you use are interchangeable as well. You can use any frozen vegetable mix you choose. I recommend the President’s Choice brand just because I’ve used almost every variety that they have and I’ve always been happy with the results. But, if you have a favourite brand of your own, go for it!
If you’re using chicken instead of turkey in this recipe, you should try an Asian or Thai vegetable blend. Toss in some sesame seeds and maybe a drizzle of sesame oil, and dinner will be delicious, easy, and awesome!
Just one last thing before you get to the recipe, Dear Reader. If you’re much like me, and you prefer to complete as much week-day dinner prep as possible on Sunday afternoon, you can get this casserole ready a day or two before and just bake it off when you’re ready. Just bake the casserole for 20 minutes and allow it to fully cool. Add the biscuits, cover tightly, and refrigerate. When you’re ready to serve it up for dinner, preheat the oven to 350, remove the cover, and bake until the biscuits are done.
You can have dinner ready on a Monday night in 15 minutes. Do you know what that means? More time for you! Yippee!!!

Made this tonight with a few improvisations. Used chicken. Used cream if chicken soup with a cup of chicken gravy and a dollop of mayonnaise for creaminess. Used mixed vegetables but cut by half and included 3 duced and cooked potatoes. The result! Chicken pot pie!
