Regular pizza crust? Not keto. But keto pizza is one of the best food swaps in this entire way of eating – and I don’t say that lightly after writing six cookbooks on the subject.
The toppings you already love on pizza – cheese, pepperoni, sausage, mushrooms, olives, peppers – are all perfectly fine on keto. The problem is the dough underneath them. A standard thin-crust slice packs 20-25g of net carbs, and that’s before you’ve eaten anything else that day. Deep-dish is even worse. One slice and you’ve blown through your entire daily budget of 20-30g net carbs.
The good news is that keto pizza crusts have come a long way. Fathead dough, chicken crust, portobello mushroom caps, meat-based crusts, and chaffles all give you something to build a pizza on that keeps your carbs in check. Some of them are surprisingly close to the real thing. My 5-minute keto pizza is one of the most popular recipes on ruled.me, and it exists for exactly this reason – pizza night doesn’t have to end when keto begins.
This article breaks down the carb numbers, walks through the best keto crust alternatives, and covers your options when you’re ordering out.

The Carb Problem with Regular Pizza
Pizza crust is made from wheat flour, yeast, water, and sugar. It’s essentially bread shaped into a disc – and like all bread, it’s primarily starch. The starch converts to glucose during digestion, raises blood sugar, triggers insulin, and shuts down ketone production. That’s the mechanism that makes regular pizza incompatible with keto.The ketogenic diet works by keeping carbohydrate intake low enough to maintain ketosis – typically under 20-50g per day. Starch-heavy foods like bread and pizza dough rapidly exceed this threshold. See Ketogenic Diet – StatPearls, NCBI.
Here’s what the numbers actually look like across different crust types, per slice:
| Crust Type | Serving | Total Carbs | Fiber | Net Carbs |
|---|---|---|---|---|
| Thin crust (14″ pizza) | 1 slice (1/8) | 23g | 1g | 22g |
| Regular hand-tossed | 1 slice (1/8) | 28g | 1g | 27g |
| Deep-dish/pan | 1 slice (1/8) | 33g | 2g | 31g |
| Store-bought cauliflower crust | 1 slice (1/8) | 20g | 2g | 18g |
| Fathead dough (homemade) | 1 slice (1/4) | 5g | 1g | 4g |
The numbers speak for themselves. Even thin crust – the option most people assume is the “lighter” choice – delivers 22g of net carbs in a single slice.USDA FoodData Central nutritional data for pizza crust varieties. Values represent averages across commercial pizza products. See USDA FoodData Central – Pizza. That’s your entire day’s carb budget gone before you’ve had breakfast, lunch, or a single vegetable.
Notice that store-bought cauliflower crust isn’t the savior it’s marketed as. Most commercial cauliflower crusts add rice flour, tapioca starch, or cornstarch as binders, which pushes the carb count back up to 16-25g per serving. “Cauliflower” on the label doesn’t automatically mean low-carb. Always flip the box and check. For a refresher on how to read these labels correctly, the net carbs vs total carbs guide breaks down what to subtract and what to count.
The toppings themselves, though? They’re not the issue. A typical pizza topping spread of mozzarella, pepperoni, and mushrooms adds roughly 1-3g of net carbs per slice. The carb load is almost entirely in the crust.
Best Keto Pizza Crust Alternatives
This is where keto pizza gets fun. There are five crust alternatives worth knowing about, and each one works best for different situations. I’ve made all of these more times than I can count over the years, and they all have a place in the rotation.
Fathead Dough
This is the one. If you only try one keto pizza crust, make it fathead dough.
The base is simple: shredded mozzarella, cream cheese, almond flour, and an egg. You melt the cheeses together, mix in the flour and egg, roll it out, and bake. The result is a crust that’s crispy on the bottom, slightly chewy in the middle, and holds toppings without falling apart. At about 3-4g of net carbs per serving, it fits comfortably into a keto day.
My 5-minute keto pizza recipe uses this exact approach, and it’s been one of ruled.me’s most-visited pages for years. Pizza night at our house happens weekly, and fathead dough is what we reach for almost every time. The trick is getting it thin enough – roll it between two sheets of parchment paper until it’s about 1/4 inch thick, and don’t skip the pre-bake step before adding toppings. That’s what gives you the crisp base instead of a soggy center.
Chicken Crust
Chicken crust sounds strange until you try it. You blend cooked chicken breast with egg and parmesan, press it flat, and bake it into a thin, firm base. The texture is more like a cracker than bread – it’s crunchy, holds up well, and adds protein instead of carbs. Net carbs are essentially zero from the crust itself.
Our buffalo chicken crust pizza is a good place to start. It works especially well with bold toppings – buffalo sauce, ranch, jalapeños – because the crust is neutral enough to carry strong flavors without competing. If you’re doing higher-protein keto or you’ve already used most of your fat macros for the day, this is the crust to pick.
Portobello Mushroom Caps
Portobello caps are the fastest option. Remove the stems, scrape out the gills, brush with olive oil, and you have a ready-made pizza base that takes about 10 minutes to bake. Each cap runs about 2-3g of net carbs.
The trade-off is size – you’re making personal pizzas, not a full pie. But that’s actually an advantage for portion control. Load them with sauce, cheese, and your toppings of choice, then broil for a couple minutes at the end to get the cheese bubbly and slightly browned. Our portobello personal pizzas recipe has the full method. These are great for weeknight dinners when you want pizza flavor without spending 30 minutes on dough.
Meat Crust
A meat crust is exactly what it sounds like – seasoned ground beef, pork, or a mix of both pressed into a thin layer and baked until firm. It’s dense and hearty, more like a deep-dish base than a thin crust, and essentially zero-carb from the crust. Think of it as a meatloaf that happens to have pizza toppings on it.
This works best when you season the meat well before pressing it out. Italian seasoning, garlic powder, salt, and a little parmesan mixed into the ground beef give it flavor that works with pizza sauce and toppings. Bake the crust alone first for about 15 minutes, drain any grease, then add sauce and toppings and bake again. Check out the cheesy pizza crust pizza for a version of this approach.
Chaffle Base
Chaffles – cheese plus waffle, made in a mini waffle maker – have become a keto staple for good reason. Mix shredded mozzarella with an egg, pour it into a mini waffle maker, and you get a crispy, structured base in about 3 minutes. Two chaffles side by side make a personal pizza that’s about 1-2g of net carbs total from the crust.
The waffle grid pattern holds sauce surprisingly well, and the cheese gives it a crunch that’s closer to a thin crust than most other alternatives. If you don’t already own a mini waffle maker, it’s worth the $15 investment – chaffles work as sandwich bread, burger buns, and pizza bases. They’re one of the most versatile tools in keto cooking.
Ordering Keto at Pizza Chains
Making pizza at home is the easiest way to control the carbs, but you won’t always be in your own kitchen. Here’s how to handle pizza night out without blowing your macros.
Blaze Pizza
Blaze Pizza is one of the few national chains that offers an actual keto crust option. It’s made with flax, eggs, and cheese – similar in concept to fathead dough. The crust itself runs about 6g of net carbs for the whole thing, which makes it the easiest keto option at any pizza chain right now. Load your toppings the same way you would any other Blaze order and you’re looking at a full pizza for under 10g net carbs depending on your choices.
The Toppings-on-a-Salad Move
At most pizza places that don’t offer a keto crust – Domino’s, Pizza Hut, local spots – your best bet is ordering pizza toppings over a salad. Ask for grilled chicken, pepperoni, sausage, olives, peppers, and cheese on top of a bed of lettuce. Some places call this a “pizza salad” or will just build it if you explain what you want. It’s not pizza in form, but the flavor profile is surprisingly close when you’ve got the right toppings together.
The Topping Scrape
It’s not glamorous, but it works in a pinch: order a regular pizza and eat the toppings off the top. You’ll leave some sauce and cheese behind on the crust, but you’ll also avoid most of the carbs. This is the move when you’re at a group dinner, someone’s ordered three pizzas, and there’s no other option. I’ve done it plenty of times – it’s not my first choice, but it keeps you in ketosis without making a scene.
Papa John’s and Similar Chains
Papa John’s doesn’t have a keto crust, but their wings are a solid alternative – grilled rather than breaded. Pair them with a side salad and you’ve got a meal that fits your macros. The same approach works at most pizza chains: skip the dough, look for grilled proteins and vegetables on the menu, and treat the pizza place like any other restaurant where you need to navigate around the carbs. Check the keto food list before you go so you know what toppings and sides are safe.
Key Takeaways
- Regular pizza crust has 20-31g of net carbs per slice depending on thickness – enough to use up your entire daily keto budget in one piece.
- The toppings aren’t the problem. Cheese, meat, and vegetables are all keto-friendly. It’s the wheat-flour dough underneath that makes regular pizza incompatible with ketosis.
- Fathead dough is the best all-around keto pizza crust – crispy, chewy, and about 3-4g of net carbs per serving. It’s what we use for weekly pizza night.
- Chicken crust, portobello caps, meat crust, and chaffles are all solid alternatives depending on your macros and how much time you have.
- Store-bought cauliflower crust is usually not keto-friendly. Most brands add rice flour or tapioca starch that pushes net carbs to 16-25g per serving.
- Blaze Pizza’s keto crust is the best chain option at about 6g net carbs. At other chains, order toppings over a salad or eat toppings off a regular slice.
Frequently Asked Questions
How many carbs are in a regular slice of pizza?
A single slice of regular thin-crust pizza has around 20-25g of net carbs – almost your entire daily keto budget. Deep-dish runs even higher at 30-35g per slice. The crust is the problem, not the toppings. Cheese, pepperoni, sausage, and vegetables are all keto-friendly on their own.
What is the best keto pizza crust?
Fathead dough is the gold standard for most people. It’s made from mozzarella, cream cheese, almond flour, and an egg – and the result is a crust that’s crispy on the outside, chewy on the inside, and comes in around 3-4g net carbs per serving. Our 5-minute keto pizza uses this base and it’s one of the most popular recipes on the site.
Can I order keto pizza at a restaurant?
Some chains are making it easier. Blaze Pizza offers a keto crust option with around 6g net carbs. At most other pizza places, your best move is ordering toppings over a salad or asking for an uncrustable – just the toppings baked without the dough. It’s not on the menu everywhere, but many local shops will do it if you ask.
Is cauliflower crust pizza keto-friendly?
It depends on the recipe. Homemade cauliflower crust can be keto-friendly at around 6-8g net carbs per serving. But most store-bought and restaurant cauliflower crusts add rice flour, cornstarch, or tapioca starch to hold everything together – which pushes the carb count to 16-25g per serving. Always check the label before assuming cauliflower means low-carb.
Will one slice of regular pizza kick me out of ketosis?
Probably. One slice of thin-crust pizza has 20-25g of net carbs, which is right at or above the daily limit for most people on keto. If that’s the only carb source you eat all day, you might stay in ketosis – but practically, that’s very hard to pull off. If you want pizza on keto, the net carbs work out much better with a keto crust.
