Keto Pizza Casserole

Spread the love <3

Upon request from a reader, I ventured into the world of Ketogenic, aka "Keto", cuisine to bring you this Keto Pizza Casserole. I happen to be very well versed in nutrition as it is just another hobby of mine. I've done the whole meal planning thing quite a bit and have just been generally obsessed with nutrition and health food for, well, a long time. Let's just call it years and years 😉 So I did feel like I had a bit of an upper hand having all the macro knowledge that I do when I began planning a Keto recipe. I have never personally adhered to a Ketogenic diet for a couple of reasons. I happen to have a very lean build so I've never chosen a diet for the purpose of losing weight. My health goals are typically to gain muscle or, as strange as it sounds, to gain weight overall. I also have a very high metabolism and with all of my macro dieting experimenting I've done, I know that my body produces the results that I look for when I am consuming an OBSCENE amount of carbs. So that being said, the Ketogenic diet has never called to me, per se. Different strokes, different folks. However, I do appreciate the health benefits the research surrounding the Ketogenic diet describes this diet as having for those with epilepsy and diabetes. Alas, I love a challenge and was absolutely going to take up the opportunity to please a reader 🙂

When people think low-carb, the last thing I'm sure that comes to mind is pizza. But I do not believe that anybody should ever have to cut pizza out of their diet, carbs be darned. So I bring all of you Ketogenic diet eatin' folk this Keto Pizza Casserole! Because if I was on the Keto diet, I really wouldn't be because I would still be eating pizza 😉

What does Ketogenic mean?

I'm not going to go into great detail about the Keto diet, I'm just going to give you a quick rundown. A typical Ketogenic diet requires that you eat a maximum of 20 grams of carbs daily. The goal of a Ketogenic diet is to stop feeding your body the carbohydrates that it likes to use to burn as fuel. When you restrict the number of carbs your body has to break down into energy, it will start to break down your stored fat instead creating molecules called ketones to use as a new fuel source. For the sake of this recipe, all you need to know is that I calculated the number of carbohydrates for you and each serving will have only 7.2 grams of carbs.

Brown the meat first.

That's right. This recipe calls for a little bit of combination cooking, it's not all done in the slow cooker. Most of the work is still done in the slow cooker, but we are going to brown the meat first with some butter, seasonings, fresh garlic, and just a tad of diced red onion. The reason we're doing this is to keep the cheese from burning. If we were to build this casserole in the crock pot using raw turkey, by the time the turkey was completely cooked, the cheese would likely be burnt to a crisp. While I don't really have many qualms with the flavor of burnt cheese, or anything cheese flavored really, my goal here is a pizza consistency not that of a Cheez-It.

Parmesan is worth a few extra carbs.

Mozzarella is pretty much carb-free, perfect for Ketogenic recipes. Parmesan is not carb-free. But I love the bite that Parmesan adds to meals so it seemed worth it to me to sacrifice a few carbs and use a mixture of mozzarella AND Parmesan. Had I not done this, I probably would not have needed to water down the pizza sauce like I did (you'll read about this shortly.) If you want to cut out some extra carbs, this is the perfect step for you to alter and still get basically the same results that I got as the final dish. To cut carbs, simply replace the same amount of mozzarella for the Parmesan listed in the recipe (basically double up on mozz and 86 the parm altogether.) 😉

The pizza sauce.

Is what made this recipe a bit challenging. Tomato sauces are stockpiled with carbs. So I cheated a little bit and mixed some water in with pizza sauce to stretch the sauce a ways and still keep the carb count low. But I did not want to sacrifice flavor too much by doing this so it took some trial and error. I landed on a 2:1 ratio of pizza sauce to water. I used 12 ounces of pizza sauce, mixed it with 6 ounces of water, and landed on 18 ounces of the sauce/water combination. I like a lot of sauce on my pizza 🙂

7) Sprinkle 1/2 cup of each cheese over the sauce layer.

8) Cover the cheese with the 1/3 of the jalapeno slices, and the rest of the bell peppers, red onions, and black olives (I set aside a small amount of olives to put on the very top layer for presentation purposes; feel free to do the same.)

10) Pour the rest of the pizza sauce mixture evenly over the turkey meat.
11) Sprinkle 1/2 cup of each cheese over the sauce.

  1. There are many foods that improve with some separate preparation and cooking, I don’t know why people don’t think of it more often.

    The best part of the internet seems to be finding recipes that are healthy and still have flavor, and this looks like one of them. Thanks!

    1. I think too often people get lost in the convenience of slow cooking. While I am promoting its overall convenience, I do agree that some recipes are just better when you execute them with separate steps. They can’t all be dump and go, unfortunately. This one is worth the extra step for sure 🙂 Thank you for your comment, Sharon!

  2. Hi
    Apart from now being made to feel very hungry , the recipe looks very easy to follow so I will have to at some point try to make this dish . I like the fact that you have explained a little more than just the recipe and how to cook the dish , explaining about the benefits of the ingredients to use , ie. how many carbs are in certain ingredients etc .

    1. Thank you, Darren! It seemed worth it to me to go into greater detail about the Keto aspect of this one since the Ketogenic diet is not yet common knowledge. The carb intake either makes or breaks ketosis, so I wanted to ensure that people knew exactly how much of this would produce how many carbs. Meal planning is hard enough. I figured the least I could do was the math for my own recipe 😉

  3. Wow!! This sounds really, really good! We’ve been changing our eating habits over the past few years for better health. Not so much to lose weight, but just to have better over all health. We started by going more paleo and are now adding keto. I’ve been trying to find some good Keto recipes.

    This looks amazing and possibly might be just a little bit spicy with the jalapenos. Am I right? Just what my husband likes. I will definitely be trying this recipe. And will look around your site to see what else I can find. Thank you for sharing this recipe!

    1. Thank you for the comment, Lynn! I am guilty of erring on the side of spicy for my recipes. However, you could very easily just skip the jalapenos for this recipe. An entire jalapeno holds less than 1 gram of carbs in it so the Keto math would not change for carb intake if you just did not use one. Or, you could just take the seeds out of the jalapenos. That’s where most of the heat lies anyway! I hope you enjoy this recipe as much as we did! Pizza and dieting can now go hand in hand. What a time to be alive!

  4. This one is a winner Caitlyn! I’m into keto not for losing weight but because it is an extremely effective way to avoid a lot of the diseases of getting older. I admit I have missed pizza. Your recipe sounds delicious and the messy part sounds like fun.

    Thanks for indulging your keto diet fans.


    1. Thank you, Austin! I am happy to have brought the prospect of pizza back into your life! I am also happy to hear that the Keto diet has been effective for you! As stated in my post, different strokes for different folks. I truly believe that just because a diet works for one person, that does not necessarily guarantee that it will work for everyone. We all just need to experiment with intake and decide over time what works best for our own molecular build. The Keto diet has come in really strong with the health benefits that it provides, and that is what matters most. That it IS working for some. Keep up the healthy living, Austin!

  5. This keto pizza casserole looks amazing. Gonna have to try it this weekend. Thank you so much for posting this.

    1. Thank you, Frank! If I do say so myself, it was amazing 😉 I was actually shocked at home much I didn’t miss the bread/crust aspect of the pizza. Personally, I’m a huuuuuge carb fan. But this casserole still absolutely hit the spot! I hope you enjoy it!
