Keto Burger Buns
These keto burger buns are soft, slightly elastic, and hold a juicy patty with sauce without going soggy. The dough needs no rising time and comes together in 10 minutes. After another 12 to 14 minutes in the oven, you have buns that come surprisingly close to the original.

How to make them
-
Preheat the oven and prepare the baking sheet
approx. 2 min6 g baking powder Preheat the oven to 200 °C top/bottom heat. Line a baking sheet with parchment paper.
-
Melt the cheese mixture
approx. 3 min170 g mozzarella, shredded 60 g double-cream cream cheese or full-fat cream cheese Heat the mozzarella (170 g) and cream cheese (60 g) in a microwave-safe bowl at 600 W for about 90 seconds. Stir, then heat for another 30 seconds until everything is fully melted and smooth. Alternatively, melt in a bain-marie or in a small pot over low heat.
-
Mix the dry ingredients
approx. 1 min100 g blanched almond flour 10 g psyllium husk powder 0.5 TL salt Combine almond flour (100 g), psyllium husk powder (10 g), baking powder (6 g), and salt (½ tsp) in a bowl.
-
Bring the dough together
approx. 3 min2 Stück eggs 5 ml apple cider vinegar approx. 1 tsp Separate 1 egg: place the yolk in a small bowl and set aside for step 5. Add the 2 whole eggs and the egg white together with the apple cider vinegar (1 tsp) to the melted cheese mixture and quickly whisk smooth with a fork or hand mixer. Work in the dry mixture until you have an even, sticky dough.
-
Shape the buns
approx. 3 minDivide the dough into 6 equal portions. With wet hands, shape each portion into a flat round (approx. 9 cm in diameter, about 2 cm tall) and place on the baking sheet. Do not shape them too tall, the buns still rise slightly in the oven.
-
Brush and sprinkle
approx. 2 min15 g sesame seeds for sprinkling Mix the reserved egg yolk from step 4 with 1 tsp of water and lightly brush the buns. Distribute the sesame seeds (15 g) evenly over the buns and press in gently.
-
Bake
12 to 14 minBake the buns in the preheated oven at 200 °C for 12 to 14 minutes until the surface is golden brown and the buns sound slightly hollow when tapped.
-
Let them cool
approx. 10 minLet the buns cool on a wire rack for at least 10 minutes before slicing and topping them. While warm they are still soft and tear more easily.
You did it! Enjoy every delicious bite.
Which tips help for perfect keto burger buns?
- Cut the mozzarella into small cubes or use it shredded, so it melts more evenly.
- Shape the dough with wet hands so it does not stick.
- Form the buns flat rather than tall, they still rise slightly in the oven.
- Briefly toast the cut side before adding toppings so the bun does not get soggy.
- Press in sesame seeds or nigella seeds right after shaping so they stick properly.
Why are these burger buns keto-friendly?
Classic wheat burger buns deliver 45 to 50 g of carbs per roll, which blows a ketogenic daily budget of 20 to 50 g on the bun alone. This version comes in at about 2.1 g net carbs per piece because the structure is built from melted mozzarella and almond flour instead of gluten and starch. The macro split lands at roughly 14 g fat, 11 g protein, and just 2.1 g net carbs per bun, a profile that fits into any ketogenic day. The fat-to-carb ratio stays solidly keto-compliant even with patty and toppings.

The Fathead principle applied to buns
The combination of melted cheese and almond flour (often called Fathead dough) gives the bun an elastic, bread-like texture without gluten. The mozzarella melts, binds the almond flour, and produces a slightly golden, stable surface during baking. The result holds together better than pure cloud bread variants made from eggs and cream cheese alone.
Carbs in comparison
A bakery brioche bun delivers about 30 to 35 g of carbs, a standard sesame bun around 45 g. With this keto bun you stay at 2.1 g net carbs, which keeps even a double burger with tomato and onion keto-compatible without putting your daily allowance at risk.
How do I serve and vary the keto burger buns?
From my own experience, these buns also stand up well to a juicy smash burger with cheddar, jalapeños, bacon, and sauce. The key is to quickly toast the cut side in a pan or toaster. That prevents sogginess and adds a layer of roasted flavor.
Meal prep and freezing
The buns keep in an airtight container in the fridge for 4 to 5 days. To freeze, wrap each bun individually in plastic wrap and place in a freezer bag. They thaw at room temperature in about 20 minutes or can go straight into the toaster. For BBQs you can bake them the night before and toast them briefly the next day.
Variation without mozzarella (dairy-free adaptation)
If mozzarella does not agree with you, replace it with the same amount of melted coconut oil plus 2 tbsp of tapioca fiber. The texture turns a bit firmer and less elastic, but the buns still hold together. In that case swap the cream cheese for vegan cream cheese or an extra 50 g of coconut oil.

FAQ
Are these keto burger buns really keto-compliant?
Yes. At 2.1 g net carbs per bun they fit comfortably into a ketogenic daily plan of 20 to 50 g carbs. Even with a sugar-free ketchup alternative, tomato, and onion, a complete burger stays under 8 g net carbs.
Can I replace the almond flour with coconut flour?
In principle yes, but coconut flour absorbs significantly more liquid. Use only about one third of the almond flour amount (roughly 35 g instead of 100 g) and add 1 to 2 tbsp more water or an extra egg if needed. The texture will turn out a bit drier.
Do the buns fall apart when topped?
No, as long as you do not shape them too thick and toast the cut side briefly. The melted mozzarella gives them a stable, slightly elastic structure that is much sturdier than pure cloud bread variants.
Can I use the buns as regular rolls too?
Yes, they also work as sandwich rolls, for pulled pork, as a breakfast bun with egg and bacon, or as a side at a BBQ. Just shape them a little smaller when you want them as side rolls.
How do I make the buns fluffier?
Separate the eggs and whip the whites to stiff peaks before folding them in. That brings more air into the dough. Also make sure the mozzarella is only melted, not overheated, since too-hot cheese turns rubbery instead of elastic.
