Ingredients for Keto Buns

To make six soft, fluffy keto sandwich buns, gather:

• 3 cups shredded mozzarella cheese
  (Use low-moisture, part-skim mozzarella for the best texture.)
• 2 oz cream cheese
  (Adds moisture and richness.)
• 1¾ cups almond flour
  (A staple keto flour: low carb and naturally gluten-free.)
• 1 tbsp baking powder
  (Helps the buns rise and become fluffy.)
• 2 large eggs
  (Folded into the dough for structure.)
• 1 large egg (beaten, for egg wash)
• 1 tbsp sesame seeds (optional topping)

Dietary swap: If you need a nut-free option, coconut flour can be used with adjustments to liquid amounts because it absorbs more moisture.

How to Make Keto Buns — Step by Step

Step 1: Preheat and Prepare

Preheat the oven to 400°F (200°C). Line a large baking tray with parchment paper.

Step 2: Melt the Cheeses

In a microwave-safe bowl, combine the shredded mozzarella and cream cheese. Heat in 20-second intervals, stirring between each, until the mixture is fully melted and smooth. Avoid overheating — the cheese should be melted but not bubbling.

Step 3: Combine and Process

Transfer the warm melted cheese to a food processor. Add the almond flour, baking powder, and two eggs. Pulse until a thick, slightly sticky dough forms. If you don’t have a food processor, mix with a sturdy spatula and then knead by hand.

Step 4: Knead and Shape

Lightly dust a work surface with almond flour. With slightly damp hands, knead the dough briefly to smooth it (about 1–2 minutes). Divide into six equal portions, roll each into a ball, flatten slightly to bun shape, and arrange on the prepared baking tray.

Step 5: Egg Wash and Topping

• Whisk the remaining egg and brush it over the tops of each bun to give them a glossy finish.
• Sprinkle sesame seeds on top if desired for a classic bun look.

Step 6: Bake

Bake for 14–17 minutes, or until the buns are golden brown on top. Let them cool for about 5 minutes before slicing to prevent them from tearing. For an extra golden finish, briefly broil for 1–2 minutes at the end of baking, watching closely to avoid burning.

Pro Tips for the Best Keto Buns

• Don’t skip the egg wash — it gives the buns a professional, glossy finish.
• For extra structure and chew: add 1 tsp psyllium husk powder to the dry mix; it improves crumb and hold.
• No food processor? Mix by hand with a silicone spatula, then knead thoroughly until smooth.
• Shape variations: For hot dog buns, shape the dough into elongated rolls before baking.
• Make-ahead: These buns freeze well—freeze individually wrapped, then reheat in a toaster oven or microwave.

Frequently Asked Questions

• Can I make keto buns ahead?
  Yes. Bake, cool completely, wrap individually, and freeze. Reheat in a toaster oven or microwave when ready to use.
• What’s the secret to the best keto buns?
  A balanced cheese-to-flour ratio and a short knead to develop a cohesive, pliable dough.
