Low carb turkey casserole, made with cauliflower rice, green beans, and cheddar cheese can be on the table in under 45 minutes. It’s the PERFECT way to use up your leftover turkey from Thanksgiving, but you can easily make it any time of year.
Leftover Turkey Casserole: The Most Delicious Way to Use Up Your Leftovers
I’m not usually a big casserole person, but I recently made a few classic casseroles for one of my freelance clients and I finally understand the appeal.
They’re cozy as can be, super easy to make, reheats well (perfect to prep for lunches!), and can even be made ahead and frozen for later.
I’m officially a casserole convert.
This leftover turkey casserole is seriously so good.
Have you ever finished a really good dinner and immediately started looking forward to having leftovers for lunch the next day? This recipe gives you that feeling.
Leftover turkey casserole is a classic after Thanksgiving for obvious reasons. But, unfortunately, most turkey casserole recipes are pretty bland and have a muddy flavor from things like canned cream of mushroom soup.
This low carb turkey casserole doesn’t have any of that. Instead, I spiced things up with cajun seasoning and jalapeno pepper.
I also added red bell pepper and green beans to keep things tasting fresh and vibrant. Casserole not your thing? Try using up your leftover turkey with this turkey rice soup.
What you’ll love about this recipe:
- Low Carb – Made with cauliflower rice!
- Made with fresh ingredients – Step away from the can of “cream of soup.” We’re using fresh, wholesome ingredients in this turkey casserole!
- Reheats well – Perfect for meal prep! If you’re tired of turkey, you can even freeze it for later.
Ingredients in Cajun Turkey Casserole
- Cooked turkey. Leftover Thanksgiving turkey is ideal, but I grabbed a package of roast turkey breast from Trader Joes that was perfect in this recipe. Just be sure not to use deli meat turkey. You could also use a rotisserie chicken or sautee turkey tenderloin.
- Green Beans. I prefer to use fresh green beans in this recipe, but frozen beans are also ok. If you use fresh beans, be sure to trim the ends!
- Red Bell Pepper. I know red peppers cost a little more than green peppers, but they have a sweeter flavor than green peppers. They also add a pop of color that this leftover turkey casserole really needs.
- Jalapeno Pepper. Jalapeno pepper adds a little extra spice to this casserole. Add more or less, depending on how spicy you want your casserole to be. 1 small jalapeno is a good starting place.
- Cajun seasoning. Cajun seasoning is what gives this casserole it’s flavor, so you don’t want to skimp here. Store-bought cajun seasoning can be hard to find, so here’s my cajun seasoning recipe.
- Cauliflower Rice. Cauliflower rice keeps this casserole low carb, and means it’s easier to make since you don’t have to mess with boiling rice! I love cauliflower rice, but in this recipe, you can barely notice the cauliflower flavor with all of the other ingredients.
- Sharp White Cheddar. I strongly prefer to grate my own cheese. It melts better than pre-shredded cheese and has better flavor.
- Eggs. Eggs help bind everything together. Be sure to take the pan off the stove before you add the eggs – you don’t want them to scramble!

Very tasty! I didn’t have leftover cooked turkey so seasoned a turkey breast with my Cajun seasoning and roasted then added. Extra is always nice.
