This keto chicken pesto pizza is my go-to way to use up leftover chicken. I take my fathead pizza dough, roll it out, and load it with a garlic-pesto double sauce that I landed on after testing this recipe more times than I can count.

Here's the thing about pesto on pizza. If you just spread it straight on the crust, it can get greasy or too sharp. I start with a thin layer of garlic sauce first, then add the pesto on top. That garlic base mellows everything out and gives you this creamy, savory layer underneath. It's the difference between pesto pizza that's one-note and one that actually has depth.

For the chicken, use whatever you have. Rotisserie, grilled from last night, baked chicken you meal-prepped on Sunday. I almost always use leftover chicken because it turns fridge cleanout into something my family genuinely looks forward to. One reader told me her pesto-skeptic son ate two slices and asked for more. That tracks. The garlic sauce underneath tames the pesto enough that even people who think they don't like it come around.

If you've never worked with fathead dough, the food processor is your best friend. I've done it with a hand mixer (dough flies everywhere, trust me), by hand (messy and slow), and in the food processor (done in about 30 seconds, no mess). I always go food processor now. The dough comes together into this smooth, pliable ball that rolls out easily between two sheets of parchment paper.

I roll mine to about 1/4 inch thick. Thinner gives you a cracker-crispy crust. Thicker means an extra 3-4 minutes in the oven. Watch for two things at 400 degrees: crust edges browning and cheese going bubbly. Mine usually hits that around 13-14 minutes, not the full 15.

The cherry tomatoes are optional, but I keep them. They burst a little in the oven and give you these pockets of bright acid that cut right through the richness of all that cheese and pesto. If you're worried about a soggy crust, halve them and pat dry with a paper towel first.

If you love keto pizza as much as I do, I have a whole lineup worth trying. My chicken crust pizza skips the fathead dough entirely. The keto deep dish pizza is for when you want something thick and loaded. Grilled pizza is what I make all summer. And if you want the pesto-chicken combo without the crust, try my keto pesto chicken or creamy pesto chicken as a standalone dinner.

If you don’t have my keto garlic sauce made ahead, spread 2 tablespoons of pesto on the crust in its place.

Why I Add Baking Powder and Xanthan Gum

fathead pizza crust

Basic fathead dough is just mozzarella cheese, almond flour and egg. My version also has baking powder and xanthan gum. They help the dough rise and give it structure, so the crust puffs up with a chewy middle and a crispy outer edge.

Extra dough keeps in the refrigerator for up to one week or in the freezer for up to 6 months.

Keto Chicken Pesto Pizza Ingredients

Step by Step Instructions

  1. Preheat oven

    Preheat oven to 400 degrees.

    oven heated to 400 degrees
  2. Melt the cheese

    Place 3.5 cups of mozzarella in a microwave-safe glass bowl. Microwave for about two minutes until cheese is melted. Stir to combine and make sure all of the cheese is melted. Remove from microwave and let the mixture cool while combining the remaining ingredients.

  3. Mix dry ingredients

    In a large separate bowl, mix together the almond flour, baking powder, xanthan gum, and salt. Set aside.

  4. Combine egg and cheese

    Add in your egg to the melted mozzarella cheese. Mix until combined using an electric mixer.

  5. Mix dough

    Slowly add the almond flour mixture to the cheese mixture. Using an electric mixer or food processor, stir until the dough is combined and uniform. Don’t be surprised if dough goes flying if you are using the mixer! The easiest, mess free way is to use a food processor to combine the ingredients. If you don’t have an electric mixer or food processor, I recommend kneading the dough by hand until it comes together. This is a messy and time-consuming process, but the end result is the same: fat head pizza.

  6. Knead pizza dough

    Once combined, form dough into a ball. Knead the dough a couple of times on a lightly almond floured surface to ensure the dough is uniform in appearance and all ingredients are fully combined.

  7. Place in between parchment

    Place the dough in between two pieces of parchment paper.

  8. Roll out crust

    Roll out dough to desired thickness: about 1/8 to 1/4 inch thick. Remove top parchment layer and place on top of a baking sheet.

Frequently Asked Questions

Can I use a different type of cheese instead of mozzarella?

I've tried provolone and it works, just gives you a sharper bite. Cheddar melts fine but doesn't get that same stretch. My go-to swap is a provolone-mozzarella mix when I want something different. The key is picking a cheese that melts well, because you need it to bubble up in the oven. I've also made a pizza bowl version when I want extra cheese without worrying about crust at all.

What can I use instead of almond flour for a nut-free option?

I've tested this with coconut flour and it works, but you need way less since coconut flour absorbs so much more liquid. I start with about 1/2 cup and add more until the dough comes together. The texture ends up slightly more tender and a bit less sturdy, but it still holds toppings without buckling.

Can I freeze the fathead dough before adding toppings?

I freeze fathead dough all the time. I roll it out, leave it on the parchment, and freeze it flat. Once solid, I wrap it in plastic and stack them. Thaw on the counter for about 20 minutes before topping and baking. I usually make a double batch and freeze half so pizza night takes even less effort.

Should I reheat leftovers in the oven or microwave?

Oven, every time. 350 degrees for about 8 minutes and the crust stays crispy. I learned the hard way that the microwave turns fathead dough rubbery. If you're really short on time, a hot skillet with a lid works too (crispy bottom, melty top). I store my leftovers in an airtight container in the fridge and they keep 3-4 days.

Can I make this in an air fryer?

I've done it and it works for smaller personal-sized rounds. 370 degrees for about 8-10 minutes. The crust gets extra crispy on the edges, which I actually prefer. The catch is size: you need to split the dough into individual rounds that fit your basket. I usually get two personal pizzas out of one batch. For something that fits an air fryer basket without reshaping dough, my crustless pizza works perfectly.

How do I know if my store-bought pesto is keto-friendly?

I always flip the jar and check the sugar and oil. A lot of store-bought pesto sneaks in added sugar or cheap filler oils like soybean or canola. I look for under 1g sugar per serving and real olive oil as the fat source. Rao's and Primal Kitchen are two I've used that keep it clean. If the label lists sugar in the first five ingredients, I skip it.

Will cherry tomatoes make the crust soggy?

Not if you prep them right. I halve mine and give them a quick pat dry with a paper towel before they go on the pizza. I've been making this with cherry tomatoes for years and have never had a soggy crust. Fathead dough is dense enough to handle a little moisture. Just don't pile on a full pint.

How do I keep the dough from sticking when I roll it out?

Two pieces of parchment paper, one on top and one underneath. I tried dusting the surface with almond flour and it works, but it makes everything gritty. Parchment gives you a clean roll every time with zero sticking. If the dough feels tacky even between parchment, I pop it in the fridge for 10 minutes to firm up before rolling.

Do you think I can mix the dough the night before? This is my first fathead pizza and your recipe is the one I’m trusting!! Thanks!

Pat the bell pepper dry or it’ll steam the crust.

Honestly, melting mozzarella in a microwave to make pizza dough seemed like a joke the first time I read it. Made it anyway. Once the mixer pulled it into actual dough I stopped second-guessing myself. I was braced for the cherry tomatoes to make it soggy in the middle, but the crust held clean – apparently that’s what the xanthan gum is for. Does this work with rotisserie chicken, or does how you cut it matter?

Reply

Annie Lampella

Rotisserie works great here. I’d shred it rather than dice, it spreads thinner so you don’t get wet pockets on top of the pesto.

Reply

Maria

Roasted bell pepper against pesto hits a sweetness no tomato-based version gets close to. Cut the chicken smaller than you think, the top goes wet otherwise.

Reply

Annie Lampella

The sweetness from the bell pepper does something to pesto you can’t get from tomato at all. I learned the chicken size lesson the hard way – smaller dice, under half an inch, and the top stays dry.

5.1 net carbs per slice is what finally got me to try fathead dough. I cook a fair amount but I’d been putting this off (xanthan gum is one of those ingredients I’ve bought twice and never actually used). Crust held up under the pesto and cherry tomatoes, no sogginess anywhere. Does the dough freeze before baking, or is it better to bake first and freeze after?

Reply

Mei X.

Not Annie but I’ve baked first then frozen and it reheats fine in the oven. Haven’t tried freezing the raw dough so can’t say how that holds up.

Confession: I once bought a backup bag of shredded mozzarella just to have it standing by while the first one melted. That tells you where I’m at with this recipe. By batch eight or nine I switched to fresh mozzarella on top, and the way it pulls when you slice it is just different. Hard to go back. The rotisserie chicken is the real unlock though, I keep a container in the fridge most weeks so this stays a weeknight option with zero planning. The macros are kind of absurd: 27g protein, 5.1 net carbs. I keep double-checking the numbers because it doesn’t feel like it should work out that cleanly. Also started keeping a second dough ball in the freezer on batch nights. Presses out after about ten minutes on the counter and somehow comes out crispier than fresh dough. Did not see that coming.

Reply

Annie Lampella

The frozen dough thing tracks. Cold start presses thinner and more evenly, I think, so you’re working from a denser base than room-temp dough gives you. Hope you never run out of dough balls, Chelsea.

Drained a jar of Trader Joe’s sun-dried tomatoes, patted them down, and used those instead of the cherry tomatoes. The oil that stays on them even after drying? It seeps into the crust edge a little and you get this crispy-oily bite right where the dough meets the topping that I keep thinking about. No moisture issue at all. The tomato flavor is just more, somehow, that acidic punch without the watery slide you get from fresh. I kept everything else exactly the same (garlic sauce, pesto, the full 3.5 cups of mozzarella in the dough) and just made that one swap, and now I genuinely can’t see going back to fresh on this one. Third time with the sun-dried version this month.

Reply

Annie Lampella

The oil-into-crust-edge thing you’re describing is exactly what happens and it’s honestly the best happy accident. I’ve used sun-dried tomatoes a few times but kept going back to fresh out of habit. Third time this month. You’ve tested it more than I have. Going to grab a jar from TJ’s and do a proper back-to-back.

Pizza was the one thing I couldn’t make work on keto. Tried a cauliflower version once and didn’t open that app again. Made this last weekend with leftover rotisserie chicken and the smell when the pesto hit the oven caught me off guard. The dough held up under all those toppings, no soggy center, which every other keto crust I’ve tried has failed at. Didn’t expect to feel this good about pizza night again.

Reply

Annie Lampella

That pesto smell gets me every time.

Reply

Brooke

Wasn’t sure the fathead dough would hold up under pesto and fresh tomatoes, but the bottom stayed crisp the whole way through.

Reply

Annie Lampella

Yeah, pesto releases way less moisture than tomato sauce. And the xanthan gum is what keeps that bottom from going soft. Most fathead recipes skip it.

I’ve been making this on Sundays for the past month and the prep workflow has gotten pretty dialed in. Double batch the fathead dough before it cools, portion it out, and you’ve got two pizzas done in basically the same time as one. The chicken folds in naturally since I usually have roasted chicken on hand anyway (it’s one of those recipes that rewards already having things prepped). Where I’d knock a star is the cherry tomatoes get watery on day two, so now I skip them on the batch and add fresh ones when I reheat individual slices. The pesto and garlic sauce layer holds up completely fine, which surprised me. Cold slice the next morning is legitimately good, and that’s not something I can say about most fathead pizzas.

Reply

Annie Lampella

Yeah, tomatoes don’t hold once they’re baked. Fresh on reheat is smarter. Double batching the dough saves so much time, I should add that to the recipe notes.

Natalie

My husband said this tasted ‘fancier than our usual pizza nights’ and I didn’t tell him it was because I used two sauces (the garlic and the pesto).

Reply

Annie Lampella

Ha. Two sauces and he had no idea. I kept that secret from my family the first few times too.

Roll the fathead dough between two sheets of parchment. Top sheet peels right off and the crust slides onto the pan in one piece. Four stars because I lost half my first attempt before I figured that out, but every batch since has been clean.

Reply

Annie Lampella

First one is always a write-off with fathead. Part of the deal. Four stars is fair.

There was this little spot near my college apartment that did a chicken pesto pizza I ate probably once a week senior year. I haven’t thought about it in years (three years of keto, so the timing makes sense) but one bite of this and I was back there. The garlic sauce layered under the pesto is exactly what got me.

Reply

Annie Lampella

That garlic layer under the pesto is what makes it. I almost skipped it the first time I tested this and I’m so glad I didn’t.

Reply

Holly

Love this one. The pesto under the chicken instead of just on top is the move. One tip: my first attempt I rolled the dough too thick and the center needed an extra 8 or 9 minutes. Once I got it thinner (more than I expected for a fathead dough) it baked evenly and those edges got properly golden. Measure as you go, especially your first time with this dough.

Reply

Annie Lampella

Thinner than it feels like it should be, right. I roll mine between two sheets of parchment so I can get it there without it tearing. Makes a big difference on the edges.

Reply

Paige

Never made fathead dough before, so totally new here. Don’t have xanthan gum on hand. Can I skip it or will the crust just fall apart without it?

Reply

Annie Lampella

Skip it. The crust holds together without it, just crumbles a little more when you slice. I’ve left it out before and it’s totally fine for a first time.

That dough is the whole thing. Once you nail it you can put pretty much any topping combo on it.
