If you’re still on the hunt for low carb Thanksgiving recipes, be sure to check out my favorite low carb side dishes. So many sides that are perfect for the holidays. And definitely don’t skip out on my low carb stuffing.

But, if you’re just reading this after Thanksgiving has passed and you’re wondering what to do with all that leftover turkey, I have the recipe for you!

How to make Thanksgiving leftover casserole:

We’re keeping things low carb and starting with cauliflower rice. I buy a bag of frozen cauli rice and steam it per the package instructions, but you can also purchase a head of cauliflower and grate it or pop it in the food processor. Add to a microwave safe bowl, add a tablespoon of water, cover tightly, and cook for about 4 minutes or until the rice is tender. Easy peasy.

You’ll add your cauliflower rice, leftover turkey, eggs, cheddar, cream cheese, and seasoning to a large bowl.

Steam some fresh green beans (or toss in some of my leftover healthy green bean casserole – you can’t mess this casserole up!) and add those to your bowl.

Stir it all together and spread into a 9×13 baking dish.

Top it off with extra cheese, because cheeeeeeeeese.

This bakes up in about 20 minutes and comes out so warm, comforting, and cheesy.

This turkey casserole is the perfect way to use up that leftover turkey!

Leftover Turkey Casserole

Put that leftover turkey to use in this simple low carb casserole.

Yield 6 servings
Prep Time 20 minutes
Cook Time 30 minutes
Total Time 50 minutes

Ingredients

  • 16 ounces riced cauliflower
  • 12 ounces frozen green beans
  • 2 cups leftover cooked and shredded turkey
  • 2 ounces cream cheese, room temperature
  • 1 clove garlic, minced
  • 3 cups shredded cheddar, divided
  • 2 eggs, beaten
  • 1 teaspoon salt
  • 1 teaspoon onion powder
  • 1 teaspoon mustard powder
  • ½ teaspoon cracked pepper

Instructions

  1. Preheat oven to 350 degrees. Spray a 9x13 baking dish with nonstick spray.
  2. If using frozen cauliflower rice, steam according to instructions on bag. If using fresh cauliflower rice, add to a microwave safe bowl along with 1 tablespoon of water. Cover tightly with plastic wrap and microwave for 4 minutes.
  3. Add green beans to a large microwave safe bowl along with 1 tablespoon of water. Cover tightly with plastic wrap and microwave for 3 minutes. Drain.
  4. Add the cooked cauliflower rice and green beans to a large mixing bowl along with the turkey, cream cheese, garlic, 2 1/2 cups of cheddar, eggs, and spices. Stir well to combine.
  5. Spread mixture into the prepared baking dish and sprinkle the top with remaining 1/2 cup cheese.
  6. Bake uncovered for 30 minutes. 

Notes

For the cauliflower rice, this dish is made extra easy by using the frozen 'steam in bag' cauliflower rice you find in the freezer section.

For the green beans, you could also use the 'steam in bag' frozen green beans rather than fresh. Alternately, canned green beans will work fine, but do not cook them before adding to the casserole.

  1. Made this last night and it was delish! I will certainly make it again. My question is how you determined the nutritional data. I use CarbManager and both my total fat and total carbs are significantly different. I used chicken breast, so I can see why the total fat might be lower when I made the recipe, but I don’t know why my total carbs is different from yours. Do you have a list of carbs per item in the recipe? My total primarily comes from cauliflower (20g), shredded cheese (12g) and green beans (22g).

      Hi Pati! So glad you enjoyed the recipe! Our nutrition is calculated automatically as we build the recipe in our recipe card program. It’s not always 100% accurate because it’s done automatically, but we usually catch it if it’s too far off.

      I haven’t tried freezing this one. I’m not a big fan of freezing cauliflower, especially after it’s already been cooked.

    1. Karly Campbell

      Yes, with most of it coming from the cheddar. You can reduce the cheese to reduce the sodium.

  2. It was delicious even my kids loved it! I have 3 picky girl teenagers and they really loved it! Anytime I make something healthy and the girls love it I feel its a great accomplishment. Thank you!

    what about a little cottage cheese instead of cream cheese to make it healthier

  4. In your video, you have cream cheese, but I don’t see it in the written ingredients. Did you use 2 oz?

  5. The video shows cream cheese but there is no cream cheese in your recipe. Just a heads up. Looks like about 4 ounces to me.

    1. Karly Campbell

      Sorry about that! It was 2 ounces, but you really can never add too much cream cheese. ๐Ÿ˜‰
