These low-carb air fryer buns use almond flour, Greek yogurt, flaxseed, egg, and unflavored protein powder instead of a cheese-heavy fathead dough. They cook at 350°F (175°C) for 10 minutes and the original calculation is approximately 3.3 grams of net carbs and 13 grams of protein per bun.

The recipe makes two individual buns in 4-inch pans or oven-safe ramekins. Slice each bun across the middle and use it for burgers, breakfast sandwiches, or any filling that needs a sturdier low-carb bread.

Why these air fryer buns work

• No fathead dough: there is no mozzarella or cream cheese in the batter.
• Fast: the buns need about 5 minutes of preparation and 10 minutes of cooking.
• Protein-forward: the original brand-based calculation provides approximately 13 grams per bun.
• Easy to portion: the batter is divided between two small pans for two evenly sized buns.

Ingredients and their roles

• Almond flour: provides the main structure. Fine almond flour gives a smoother texture than coarse almond meal.
• Plain Greek yogurt: adds moisture and tenderness. Check the label because carbohydrate counts vary by brand.
• Egg: binds the batter and helps it rise.
• Unflavored protein powder: adds structure without making the bun sweet. Flavored powder can change the taste.
• Ground flaxseed: contributes fiber and helps hold moisture.
• Baking soda: supplies lift.
• Salt: balances the mild batter.

Best pans for air fryer buns

Four-inch springform pans give the buns clean sides and a traditional round shape. Oven-safe ramekins also work, although the finished shape may be more tapered. Make sure the pans fit inside your basket with space around them for airflow. Our air fryer pans guide explains which materials and sizes are suitable.

How to make low-carb buns in the air fryer

1. Stir the almond flour, Greek yogurt, egg, protein powder, flaxseed, baking soda, and salt until the batter is evenly combined.
2. Divide the mixture evenly between two greased 4-inch springform pans or oven-safe ramekins.
3. Air fry at 350°F (175°C) for 10 minutes.
4. Insert a toothpick into the center. If wet batter clings to it, cook briefly longer and check again.
5. Let the buns cool in their pans before removing and slicing them.
6. Toast the cut sides if you prefer a firmer surface for burgers or sandwiches.

Troubleshooting

Why is the center still wet?

The pans may be deeper or narrower than the tested 4-inch size, or your air fryer may run cooler. Continue cooking in short increments and check the center with a toothpick.

Why did the bun stick?

Grease the pan lightly before adding the batter and let the bun cool before trying to remove it. A springform pan is especially helpful because its sides release.

Why did the bun crumble when sliced?

It may have been sliced while too warm. Cooling gives the egg, almond flour, protein powder, and flaxseed time to set into a sturdier crumb.

Nutrition and serving ideas

Using the original ingredient brands, each bun was calculated at approximately 240 calories, 6.6 grams of total carbohydrates, 3.3 grams of fiber, 3.3 grams of net carbs, 13 grams of protein, and 18 grams of fat. Greek yogurt and protein powder vary considerably, so calculate with your own brands when precise tracking matters.

Use the buns for burgers, egg sandwiches, pulled chicken, or deli meat and cheese. Toasting the cut surfaces helps them stand up to moist fillings and sauces.

Storage and reheating

Cool the buns completely and refrigerate them in an airtight container for up to 3 days. Reheat at 320°F (160°C) for 2 to 4 minutes, or split and toast the cut sides until warm and lightly crisp.
