I don’t understand why your picture of the baking dish shows the eggs unbroken when obviously they should be combined with the cream BEFORE adding the other ingredients… I think that would be confusing for some folks.
Hi Kathy, Thank you for your feedback! For some reason your comment ended up on the wrong post – I think you were referring to the Keto Smoked Salmon Breakfast Casserole. I understand your point and can see how that would be confusing. It was a photo mistake that I didn’t catch, and I’ve removed the photo in question so it fits with the directions.
So good! Creamy, flavorful and filling! Good use for leftover chicken!
Thanks so much for the five stars! Glad you enjoyed the recipe! 🙂
“That casserole was bomb, you should make it again.” Review from my guy who has to eat keto cooking half the time. So, it’s going in the rotation (and as a double batch so I get to actually eat some of it. )Super easy to meal prep for as well.
That is a huge compliment! Thank you so much, Gabrielle!
I wonder if this can be made a day ahead of time?
Hi Ande, Yes! You definitely can do that.
I made this tonight, and we loved it!!!
Thank you so much, Paula!
I’ve been wanting to try this and it didn’t disappoint delish
Thanks, Laura! 🙂
I can’t wait to try this! Thank you for this recipe!
Update! Made the recipe finally! It was delicious. I always try to make meals that are versatile for me and my non-keto family. I was able to serve this over some rice with a piece of garlic bread for them. Everybody was happy! Thanks for this recipe!
Yay, I’m so happy to hear that! Thanks, Lyndsey! 🙂
This is delicious! I made my first one last week and I’m making a second casserole right now. It pairs great with a salad and is a wonderful addition to the Atkins plan I’m on now. Love it!
I added a hint of tumeric to give it a lift. Was divine. Thank you for the recipe.
Thank you, JoJo! That sounds like a great idea – thank you for sharing!
So delicious!! We used grilled chicken and it was amazing!!
Thanks, Leah! I’m so glad you liked it!
I made this last night and it was so good! My husband said “you can make this any time – I love this”.
Yay! So happy to hear you and your husband liked the recipe! 🙂
Wanting to do some freezer meals – do you agree this probably would be a good one bc of all the dairy?? I’ve heard it separates after being thawed??
Looks delish!
Thank you
Hi J! You’re right that dairy does separate and become somewhat grainy when thawed. It won’t affect the taste, but it will affect the texture. This one is really heavy on the dairy, so probably not the best choice 🙁 This one is a much better option!
Absolutely delicious! Not a bad dish if you’re on a budget. Will be making this weekly.
I used low fat sour cream, cream cheese, and mozzarella cheese in this. it was so good.
This is the fifth recipe of yours I have made. Your keto mac and cheese, keto pizza, chicken crust pizza, and your chicken parmesan have all been excellent!
I’m about to make this recipe. The Parmesan cheese is this the crated kind in the jar or freshly grated block Parmesan?
This was a fabulous recipe. It was easy, fast and very satisfying! I questioned whether the Parmesan cheese used was grated or the jar kind. I used freshly grated, it was the right choice. I also used a bag of frozen broccoli from one of the warehouse stores. I cooked it for 3 minutes cut a corner off and let it drain while continuing to prep. You would have thought it was fresh, brightly colored and slightly crunchy. I will be sharing and eating this recipe again. ⭐️⭐️⭐️⭐️⭐️
Hi Teresa, thank you so much for the kind review! (And my apologies – I completely missed your earlier question!) I’m so glad the recipe turned out for you and that you enjoyed it. Thank you again!
Yummy! We are semi- new to Keto & have really struggled trying to satisfy our taste for all the foods we miss. This was really good! Thank you!
Incredibly delicious!!!! Will become a staple in my house.
Thanks so much, Denise! I’m so glad you liked it!

Is there a substitute for the heavy whipping cream. 1/2 cup of that alone is 8g of carbs. and is there a service size as far as grams or oz. I would like to meal prep this if possible.
Hi Christy! I use heavy whipping cream that contains 0g carbs, but if you want to substitute it, you could try unsweetened plain almond milk. The sauce will be a bit on the thinner side, but it should work. I don’t have the grams or ounces per serving on hand, but you can calculate it after the casserole is baked. I hope you like the recipe!
