Keto chicken and broccoli casserole baked in a skillet with sun dried tomato sauce. This is creamy, easy and cheesy keto dinner. Family friendly low carb casserole.

Broccoli could taste fantastic and your family members (even non keto) will ask for more! Steamed or cooked broccoli with chicken meat in a delicious, creamy keto sauce with mascarpone and sun dried tomatoes is really hearty low carb dish. When I make this for my family, they always ask for more. That’s why I use the biggest skillet I have.

Keto chicken and broccoli casserole recipe tips

Sun dried tomato sauce

I like sun dried tomatoes, they give so much Mediterranean flavor to every sauce. Chicken could be boring, as well as broccoli, but in combination with this sun dried tomato sauce – it’s incredibly tasty! Sun dried tomatoes have maybe more carbs than you would like to eat, so if you omit dried tomatoes here you will decrease the amount of NET Carbs for 1g per serving. But also the dish will lose that flavor and kick that makes it special.

Fried/sauteed onion for big flavor

As a base of the sauce I place finely chopped onion on a hot olive oil and stir until caramelized or browned. Onion gives fantastic flavor to almost any sauce you prepare. If you want to even more reduce carbs, omit tomatoes, but please, leave the onion because the taste is so much better when there is at least a little bit of fried onion. Always fry onion until translucent and golden brown. That will make give extra caramel flavor to your sauce.

Steamed or cooked broccoli

Broccoli is good low carb vegetable and keto lifestyle would be really boring without broccoli. I like to have steamed broccoli with this keto cheese sauce, try it it’s so easy and yummy! If you decide to cook the broccoli, don’t over cook it because it has to stay al dente. You will bake this dish also.

Chicken meat for broccoli and chicken casserole

For this keto casserole with broccoli and chicken I recommend you to use chicken tights because it will be more juicy. If you have chicken breasts it won’t be so sexy but because of this sauce, chicken breasts will be ridiculously tasty!

Keto mascarpone sauce

For this keto sauce I use mascarpone cheese. Mascarpone cheese gives super creamy and cheesy taste to this low carb casserole. Mascarpone cheese is full fat so it will nourish you with a lot of healthy fats.

How to serve keto chicken and broccoli casserole?

You can serve this yummy keto dish alone or with a bowl of garden salad or leafy green salad. We always recommend some leafy greens to add as a side dish with every food option you have.
