Why You’ll Love These Keto Onion Bagels
For anyone on a ketogenic diet, managing cravings for carb-heavy favorites like bread and bagels can be a real challenge. That’s where this recipe shines! It expertly combines almond flour, mozzarella, and cream cheese to create a dough that not only looks like a bagel but truly tastes like one. Say goodbye to dense, eggy, or oddly textured low-carb baked goods. These keto onion bagels are surprisingly light, chewy, and incredibly satisfying.
Beyond being keto-friendly, this recipe is also a fantastic option for those following a gluten-free diet. Crafted from wholesome, simple ingredients, it offers a healthier alternative to conventional bagels, which often contain highly processed flours and artificial additives. Whether you’re cutting carbs, avoiding gluten, or simply looking for a more nutritious breakfast option, these homemade bagels are a delicious solution that everyone can enjoy.

The Magic of Fat Head Dough: Your Secret to Perfect Keto Bagels
The unparalleled texture of these bagels is thanks to a revolutionary low-carb dough known as “Fat Head Dough,” or simply mozzarella dough. This ingenious combination of melted mozzarella cheese, cream cheese, and almond flour forms a versatile, pliable dough that behaves much like traditional wheat flour dough. It’s often referred to as “Fat Head Dough” because it gained popularity after being featured in the comedy-documentary Fat Head, which explored low-carb living.
When you combine and melt mozzarella and cream cheese, they create a gooey, stretchy base. Adding almond flour to this mixture transforms it into a workable dough that’s surprisingly easy to handle. Unlike many other gluten-free or keto baking attempts that can result in crumbly or dense textures, Fat Head Dough yields a result that’s remarkably soft, chewy, and holds its shape beautifully. This makes it ideal for bagels, as it can be toasted without falling apart and provides the perfect sturdy base for your favorite spreads, like cream cheese, avocado, or even deli meats.
Low-Carb Indulgence: Nutritional Benefits
One of the most impressive aspects of these homemade keto onion bagels is their incredible nutritional profile. While a typical store-bought bagel can pack around 48 grams of net carbs, each of these delicious homemade bagels contains only 5.5 grams of net carbs. This significant difference makes them an excellent choice for maintaining ketosis or simply reducing your carbohydrate intake without sacrificing flavor or satisfaction.
Made primarily from almond flour, mozzarella cheese, and cream cheese, these bagels are naturally rich in healthy fats and protein, which contribute to satiety and sustained energy. This means you can enjoy a filling and flavorful breakfast or snack that keeps you full and energized throughout the day, without the sugar crash associated with high-carb alternatives.

Beyond Breakfast: Versatile Ways to Enjoy Your Keto Onion Bagels
While these bagels are undeniably perfect for breakfast or brunch, their savory onion flavor and satisfying texture make them incredibly versatile. This recipe yields four bagels, but if you have extra ingredients and a hungry household, don’t hesitate to double the batch! You’ll find yourself reaching for them throughout the week.

Here are just a few ideas for how to incorporate these low-carb delights into your meals:
- Classic Cream Cheese Topper: The most iconic way to enjoy a bagel! Spread a generous amount of plain or flavored cream cheese for a quick and satisfying breakfast.
- Low-Carb Sandwiches: Slice them in half and fill them with your favorite deli meats, cheese, lettuce, tomato, and a sugar-free dressing for a robust lunch. They hold up exceptionally well, making them ideal for meal prep.
- Breakfast Sandwiches: Elevate your morning routine by building a breakfast sandwich with scrambled eggs, bacon, sausage, or avocado.
- Mini Pizza Bagels: Top bagel halves with a low-carb marinara sauce, shredded mozzarella, and your favorite keto-friendly toppings (pepperoni, mushrooms, olives) for a quick and easy snack or light meal.
- Savory Garlic Bread: Slice them in half, spread with garlic butter, and toast until golden for a flavorful side dish.
Storing and Reheating Your Homemade Low-Carb Bagels
Because these keto onion bagels are made with fresh, whole ingredients and without preservatives, they won’t last as long as typical store-bought bagels. To keep them fresh and delicious, store them in an airtight container in the refrigerator for up to 3 days. This helps maintain their soft texture and prevents them from drying out.

If you’ve made a larger batch or want to enjoy them over a longer period, these bagels freeze beautifully. Wrap individual bagels tightly in plastic wrap, then place them in a freezer-safe bag or container. They can be stored in the freezer for up to 1-2 months. When you’re ready to enjoy one, simply let it thaw at room temperature for a bit, then reheat it in a toaster, oven, or microwave until warmed through. A toaster will help bring back that satisfying exterior crispness!
Keto Onion Bagel Recipe: Step-by-Step Instructions
This recipe is designed to be straightforward and accessible, even for novice bakers. Follow these detailed steps to create your perfect batch of low-carb onion bagels.
Ingredients:
Here’s a complete list of ingredients you’ll need to make these low-carb bagels. For precise measurements, please refer to the recipe card below.

- Almond flour
- Mozzarella cheese (freshly grated or pre-shredded)
- Egg
- Cream cheese
- Olive oil
- Baking powder
- Onion powder
- Onion flakes
Instructions:
- Prepare Your Baking Station: Preheat your oven to 375°F (190°C). Line a sheet pan or baking sheet with parchment paper. This will prevent sticking and make cleanup a breeze.

- Combine Dry Ingredients: In a medium-sized bowl, whisk together the almond flour, baking powder, and onion powder until they are well combined. Set aside.

- Melt the Cheeses: In a separate microwave-safe bowl, add the mozzarella and cream cheese. Microwave in 45-second increments, stirring well after each interval, until the cheeses are completely melted and have formed a cohesive, stretchy ball of dough. This usually takes about 2 cycles. Be careful not to overheat the cheese, as it can become oily.

- Combine Wet and Dry: Add the egg to the melted cheese mixture. Now, add the dry ingredient mixture to the cheese and egg. Vigorously mix everything together with a sturdy spoon or spatula, or use your hands (it will be warm!) to ensure the egg and dry ingredients are fully incorporated into the dough. You want a smooth, uniform dough.

- Shape the Bagels: Divide the dough into four equal portions. Roll each portion into a smooth ball. Then, gently push your finger through the center of each ball to create a nickel-sized hole. Gently stretch the hole to ensure it doesn’t close up during baking. Place the formed bagels on the prepared parchment-lined baking sheet, making sure they are spaced about two inches apart.

- Apply Topping: Lightly brush the tops of the bagels with olive oil. This helps them brown beautifully and gives the onion flakes something to adhere to. Generously sprinkle onion flakes over each bagel.



- Bake: Bake for 15-20 minutes, or until the bagels are a beautiful golden brown on top and feel firm to the touch. Baking times can vary, so keep an eye on them.

- Cool and Enjoy: Remove the bagels from the oven and let them cool on the baking sheet for 10-15 minutes before serving. This cooling time is crucial for the texture to set properly. Then, slice, spread, and savor your homemade keto onion bagels!

Frequently Asked Questions About Keto Onion Bagels
Q: Can I substitute almond flour with coconut flour?
A: No, it’s not recommended. Almond flour and coconut flour behave very differently in baking due to their absorbency. Substituting coconut flour directly would likely result in a very dry and crumbly dough. This recipe relies on the specific properties of almond flour for its texture.
Q: Can I make these bagels ahead of time?
A: Absolutely! These bagels are great for meal prep. You can bake them, let them cool completely, and then store them in an airtight container in the refrigerator for up to 3 days, or freeze them for longer storage as described above.
Q: What if my dough is too oily after melting the cheese?
A: If your cheese mixture appears oily, it might have been microwaved for too long or at too high a power. You can try to blot some of the excess oil with a paper towel. Ensure you stir thoroughly between microwave intervals to prevent overheating.
Q: Can I customize the toppings?
A: Yes! While onion flakes give these bagels their distinct flavor, you can certainly get creative. Try adding everything bagel seasoning, sesame seeds, poppy seeds, or even a sprinkle of garlic powder for a different savory twist.
Q: What kind of mozzarella cheese is best for Fat Head Dough?
A: Low-moisture, part-skim mozzarella works best. You can use pre-shredded mozzarella, but freshly grated often melts more smoothly and can produce a slightly better dough consistency.
