Can You Eat Pizza While on a Keto Diet?

November 8, 2025 •

4 min read

Over 5 million Americans follow a ketogenic diet, often facing the challenge of giving up carb-heavy comfort foods like pizza. The good news is that you can eat pizza while on a keto diet by simply swapping out high-carb ingredients for low-carb, keto-approved alternatives without sacrificing flavor.

Quick Summary

Yes, it is possible to enjoy pizza on a ketogenic diet by utilizing low-carb crusts like cauliflower or almond flour and choosing keto-friendly toppings. Satisfy your cravings with creative and delicious versions of your favorite comfort food while staying in ketosis.

Key Points

Low-Carb Crusts are Key: Traditional wheat crusts are off-limits, but delicious alternatives like fathead dough (almond flour, mozzarella, cream cheese) and cauliflower crust are widely available and easy to make.
Choose Sugar-Free Sauce: Many store-bought pizza sauces contain hidden sugars and carbs. Opt for low-carb marinara or create your own with fresh tomatoes and herbs.
Pile on Keto Toppings: Enjoy classic pizza flavors with keto-friendly toppings such as pepperoni, sausage, bacon, mushrooms, onions, and bell peppers.
Manage Moisture for a Crisp Crust: For vegetable-based crusts like cauliflower, squeezing out excess moisture is a critical step to prevent a soggy pizza.
Use Full-Fat Cheeses: All types of cheese are generally fine for a keto diet, so feel free to use full-fat mozzarella, cheddar, and Parmesan.
Mind Your Macros: Always double-check ingredient lists and use a food tracker to ensure your homemade keto pizza fits within your daily carbohydrate limits, especially when first starting out.

The Carb Conundrum of Conventional Pizza

Traditional pizza is an obvious no-go for anyone following a ketogenic diet due to its high carbohydrate content, primarily from the wheat-based crust. A single slice of regular pizza can contain over 26 grams of carbs, making it difficult to stay within the strict daily limit of 20-50 grams required for ketosis. The high-carb crust spikes blood sugar and can kick your body out of its fat-burning state. This doesn't mean you must give up pizza forever, but it does require a strategic approach to ingredients.

Keto-Approved Crust Alternatives

Replacing the traditional crust is the most crucial step toward creating a keto-friendly pizza. Fortunately, several delicious low-carb options exist:

Fathead Dough: A popular choice made from shredded mozzarella cheese, cream cheese, egg, and almond flour. The result is a pliable, chewy crust that bakes up golden and holds toppings well.
Cauliflower Crust: For a vegetable-based option, cauliflower crust is an excellent choice. It's made by ricing cauliflower, pressing out excess moisture, and mixing it with cheese, eggs, and seasonings before baking. A single serving can have as few as 3 grams of net carbs.
Almond Flour Crust: Similar to fathead dough, but with a simpler ingredient list, an almond flour crust is sturdy and has a nutty flavor. It's a great choice for those who prefer a crisper base.
Chicken Crust: For a protein-packed and truly unique option, a crust can be made from ground chicken, Parmesan cheese, and an egg. This creates a high-protein base that is completely free of carbs.
Pork Rind Crust: Another inventive, protein-based crust utilizes ground pork rinds mixed with eggs and cheese for a crunchy, flavorful base.
Portobello Mushroom Caps: For a no-crust, single-serving alternative, large portobello mushrooms can be used as a base.

Low-Carb Sauces and Toppings

After choosing your crust, the next step is selecting keto-friendly sauces and toppings. Many store-bought sauces contain added sugars, so it's essential to read labels or make your own.

Sauce: Opt for low-carb marinara or sugar-free pizza sauce. You can also use pesto, alfredo sauce, or a simple olive oil and garlic base.
Cheese: Full-fat mozzarella, cheddar, provolone, and parmesan are all excellent keto options.
Meats: Pepperoni, sausage, bacon, and grilled chicken are all keto-friendly protein sources.
Vegetables: Most low-carb vegetables work well, including bell peppers, onions, mushrooms, olives, spinach, and jalapeños.
Fats: Add a drizzle of high-quality olive oil or some sliced avocado for extra healthy fats.

Expert Tips for the Perfect Keto Pizza

Press Out Moisture: If using a cauliflower crust, ensure you press out as much moisture as possible after cooking the cauliflower. This prevents a soggy crust.
Pre-bake Your Crust: For most keto crusts, pre-baking is essential to firm them up before adding toppings. This prevents a watery mess and ensures a sturdy base.
Watch the Sauce: Always check the nutrition label on store-bought sauces. Many contain hidden sugars. Opt for a brand with low or zero added sugars.
Don't Go Overboard on Toppings: While keto toppings are generally low-carb, piling on too many can create a soggy crust. Distribute them evenly and avoid large, watery vegetables.
Embrace Variety: Experiment with different crusts and toppings. Try a white pizza with alfredo sauce and chicken, or a pesto pizza with mushrooms and spinach. Creativity is key to keeping your diet interesting.

Frequently Asked Questions

The 'best' keto pizza crust depends on personal preference. Fathead dough offers a chewy, bread-like texture, while cauliflower crust is lighter and vegetable-based.
