Ingredient Notes

- Olive oil
- Cooked chicken - Either cooked diced or shredded chicken will work, rotisserie chicken works too but it could make the dish a little saltier.
- Marinara sauce - use a sugar-free brand like Rao's to keep it low carb.
- Cauliflower rice- we defrosted frozen cauliflower rice, fresh can be used as well. It could take a couple extra minutes to cook through.
- Mozzarella cheese - Shredding your own cheese is always recommended, pre-shredded cheese costs more and adds starch as a filler (which increases the carbs)
- Shredded Parmesan
- Cream cheese- use full-fat cream cheese to help keep the carbs down. Check the labels of various brands also.
- Seasoning- Garlic salt, ground black pepper, Italian seasoning
Variations
Use broccoli rice instead of cauliflower rice.
Swap veggie rice for white rice if you are not following a low-carb lifestyle.

Expert Tips
- This recipe is based on using pre-cooked chicken. We love to cook it in batches and then defrost it to make quick weeknight dinners. Rotisserie chicken should also work, it could be a little bit saltier so maybe cut back on added salt to the dish
- The recipe used frozen cauliflower rice that was defrosted in a microwave first. If you're using fresh cauliflower rice it'll add a couple minutes to the cooking time.
- Be sure your marinara sauce is low-carb.
- Use fresh mozzarella to keep the carb count as low as possible.
- If you love garlic, feel free to saute the cauliflower rice in minced garlic.
- Top with additional marinara sauce if you like your keto chicken parmesan casserole saucier.
- You can easily double this recipe and cook it in a 9x13 pan for a larger family or to have leftovers to use throughout the week.

Common Questions
Keto chicken parmesan casserole is a one-pan dinner, but if you prefer to serve something with it a side salad or roasted vegetables would be ideal to stay low-carb. Potatoes also make a good side if you are serving guests who do not follow a low-carb lifestyle.
Yes, this low carb chicken parmesan casserole can be frozen for up to 3-months. Bake from frozen at 350F for up to one hour, until it reaches an internal temperature of 165F. Covering with foil for the first 30-45 minutes will help prevent the cheese from burning.
Store any leftovers in the fridge in an air-tight container and eat within 4-5 days.

Notes
We used a cast iron skillet since they can go from stovetop to broiler, not all cookware can get broiled. If you don't have one skip broiling the cheese.
Double and cook in a 9x13 pan if you're serving a large group or want leftovers.
We love to meal prep chicken to freeze for easy dishes like this. Rotisserie chicken is another alternative to get dinner on the table fast but it does add more salt.
Rao's makes the best keto-friendly marinara sauce that has no added sugar, plus it tastes like homemade.
Feel free to add an extra ½ cup of marinara to the dish if you want it to be a little saucier! We love to just drizzle extra heated sauce over the top before serving.

Easy to make and very tasty 😋
Lindsey says
Can I prep this and put it in the fridge overnight and pop it on the oven the next day to cook?
WholeLottaYum says
I think that would be fine to make ahead and bake the next day. It'll take a little longer in the oven.
