Why You’ll Love This Pizza Chaffle Recipe
Delicious
A pizza chaffle is incredibly versatile. The cheese in the chaffle melts and crisps at the edges, creating a flavorful, crunchy base that tastes like a miniature pizza crust. You can season the batter to match any flavor profile you like.
Quick and Easy
These chaffles come together fast. Mix the simple crust ingredients, pour into a preheated waffle iron, and cook until the exterior reaches your preferred crispness. Add toppings and briefly broil or air fry until the cheese is bubbly.
Low Carb and Keto
Chaffles make an excellent low-carb substitute for traditional pizza crust. They are keto-friendly, gluten-free, and high in protein. Use them as pizza crusts, burger buns, or as a base for inventive low-carb meals.
What You’ll Need
Ingredients for keto pizza chaffles:
- Egg
- Shredded Cheddar Cheese — freshly grated works best. You can also use mozzarella, cheddar jack, or pepper jack.
- Pizza Sauce — use a sugar-free or low-sugar sauce for keto.
- Shredded Mozzarella Cheese — for topping; substitute with your preferred melting cheese.
- Pepperoni — traditional or turkey pepperoni are both fine.
- Optional — additional toppings like onions, mushrooms, bell peppers, Italian sausage, or fresh herbs.

Ways to change this pizza chaffle recipe:

How To Make It
Step-by-step instructions for this low-carb pizza:
Make the Chaffle Pizza Crust
- Preheat your oven to broil or set your air fryer to 400°F. Preheat your waffle maker to its highest setting.
- In a small bowl, combine shredded mozzarella (or chosen shredded cheese), one egg, and Italian seasoning. Stir until evenly mixed.
- Pour the mixture into the center of the hot waffle maker and close the lid. Cook until the outside is crisp and golden to your liking.
Assemble the Pizza
- Place the cooked chaffle on a small baking sheet or pizza pan.
- Spread 1–2 tablespoons of pizza sauce over the chaffle, add shredded mozzarella, and arrange pepperoni slices on top.
- Add any optional toppings now so they finish cooking while the cheese melts.
Broil or Air Fry
- Broil the assembled chaffle in the oven until the cheese is melted and bubbly. Watch closely to avoid burning.
- Or place the chaffle in a preheated air fryer basket at 400°F for about 5 minutes, or until the cheese is melted and the edges are crisp.
How To Serve It
- Host a family pizza night: set out a variety of toppings and let everyone build their own chaffle pizza.
- Add fresh herbs like basil or chives after baking for brightness.
- Finish with a sprinkle of grated Parmesan and a pinch of red pepper flakes if desired.
- Serve alongside a crisp green salad or a low-carb side for a complete meal.
Kori’s Tips
- Use a mini waffle maker to make two smaller chaffles, or a 6″–8″ waffle maker for a single larger chaffle.
- Scale the recipe up easily when cooking for more people.
- Make chaffles ahead of time and store them in an airtight container in the fridge for up to five days. Re-crisp in the air fryer before adding toppings, then finish under the broiler or in the air fryer until the cheese melts.
FAQs
A typical chaffle pizza has about 2 grams of carbohydrates, making it a suitable choice for a keto or low-carb diet. Exact carbs depend on toppings and sauce.
A classic chaffle is made from eggs and cheese — essentially a waffle made without flour, using cheese for structure and eggs for binding.
Chaffles are high in protein and calcium and low in carbs and sugar. They can be a good option for gluten-free or low-carb eating plans, though they are calorie-dense due to the cheese content.
Store leftover chaffles in an airtight container in the refrigerator for up to five days. Keep toppings separate until you’re ready to reheat and serve.
Reheat chaffles in an air fryer at 400°F to restore crispiness. Add toppings after re-crisping and cook briefly until the cheese melts.
