How to make a keto pizza chicken casserole

If you’re craving chicken pizza but are following a keto diet, this is the recipe for you! First, I tried baking the chicken breasts covered with spaghetti sauce in a baking dish, but the juices from the chicken made the sauce very watery, and the chicken ended up completely tasteless. It tested this recipe in three different ways before I landed on the most flavorful and delicious chicken recipe.

The winning version uses seasoned chicken breasts which I, seared to infuse the most flavor into the casserole. Then I topped the chicken with tomato sauce, cheese, pepperoni, mushrooms, green peppers, and onions and baked it until warmed and melted through. It tastes just like chicken parm pizza but without the crust! The best thing is that you can add ANY of your favorite pizza toppings to make it exactly how you like it without the added carbs.

Ingredients you’ll need for this recipe:

  • Boneless skinless chicken breasts – Searing the chicken beforehand in various seasonings gives this recipe incredible flavor. For added fat, you could sub boneless chicken thighs instead.
  • Butter & Olive Oil – For searing the chicken and adding extra fat and flavor. The butter helps the chicken to brown nicely.
  • Garlic Powder, Onion Powder, Italian Seasonings, Parsley, Crushed Red Pepper, Salt, and Pepper – Don’t be afraid of seasonings. They can take a bland dish and change the taste completely. The crushed red pepper does give the casserole a bit of a kick, so feel free to omit if desired.
  • Low Carb Spaghetti Sauce – You likely won’t find the sauce labeled low carb. Look for a marinara sauce without added sugars. In the notes of the recipe card, I’ve included several different options, as well as their carb counts. Spaghetti sauce works just as well as a pizza sauce for this recipe.
  • Mozzarella & Parmesan Cheese – What is any kind of pizza without melted, bubbly cheese on top?
  • Pepperoni, Bell Pepper, onion, and mushrooms – While these are the toppings included in this recipe, feel free to omit or sub out any topping you don’t love. There is also a list of alternative toppings in this post.

Step 2: Add butter and olive oil to a large skillet over medium-high heat. Once the skillet is hot, brown your chicken on both sides. Scoop out the chicken with a slotted spoon and place it into the casserole dish.

    1. Sure. I would prob saute it in butter with the spices for a few minutes for the additional flavor before adding it to the casserole.

    I made this recipe for my husband and I last night and we are both obsessed! I omitted the mushrooms because my husband hates them and it still turned out great. Any idea how long it stays good in the fridge? Thanks!

    1. Awesome! So glad you loved it. I personally hate mushrooms too and pick out every single one.

    This was really good! I used ground chicken and then pepperoni for my husband and mushroom/green pepper for me. Served with a salad. Did not miss the crust at all! Thank you!
