These 3-Ingredient Sweet Potato Buns are a flourless, gluten-free bread alternative made with cooked mashed sweet potato, egg, and shredded mozzarella cheese. They’re baked—not pan-fried—into bun-shaped rounds that work great for sandwiches and burgers.
What sets this recipe apart is that I designed these to work as a true bun, not a flimsy wrap. The egg and melted cheese help control moisture and give the buns enough structure to hold fillings without turning soft or falling apart.
I’ve tested several sweet potato bread variations over time, and this is the one I keep coming back to. Sweet potatoes are gentle on my digestion, and this version actually feels satisfying and practical—not fragile or gummy. These buns work for real meals, not just photos, and they’ve become one of my favorite no-yeast bread alternatives.
Why This Sweet Potato Bread Bun Recipe Works
- Designed as a true bun: These are sturdy enough for sandwiches and burgers, not flimsy like wraps.
- Only three main ingredients: Sweet potato, egg, and cheese do all the work.
- Moisture stays balanced: The egg and cheese help keep the buns soft without turning soggy.
- Baked, not pan-fried: Baking gives them a more stable bun shape without flour or yeast.
Ingredients & Substitutions
Here’s everything you need to make these sweet potato bread buns.
- Mashed sweet potatoes: This is the base of the buns and provides all the moisture. I use cooked sweet potatoes that are mashed until smooth. Steamed or boiled sweet potatoes are more neutral but slightly wetter, while baked sweet potatoes are thicker and a bit sweeter. Use 1 cup of thick mashed sweet potato—if it looks loose or watery, let it cool or blot lightly before measuring.
- Egg: The egg binds everything together and helps the buns bake up like a true bun instead of a soft wrap. It also improves browning and keeps the texture from turning gummy. You can use a flax or chia egg if needed, but the buns will be softer.
- Mozzarella cheese: Mozzarella adds structure as it melts and sets, which helps these hold up for sandwiches. I prefer shredding it from a block because it melts more evenly. Cheddar, Monterey Jack, or pepper jack also work and add more flavor. Dairy-free shreds can work, but results vary depending on how well they melt.
- Seasonings: Seasoning is optional, but it helps balance the natural sweetness of the sweet potato. Everything Bagel Seasoning works well, or you can use garlic powder, onion powder, sesame seeds, and poppy seeds. If using Everything Bagel Seasoning, I add it halfway through baking so it doesn’t burn.
How to Make My Sweet Potato Buns
Here are easy, detailed, step-by-step instructions for making my sweet potato buns. The instructions are also repeated in the recipe card at the bottom of this blog post.
How do I avoid a bitter aftertaste?
Everything Bagel Seasoning contains larger flakes of onion and garlic that can burn and leave a bitter aftertaste if sprinkled on top of the buns for the entire baking time.
Seasoning Option 1: Add the garlic powder, onion powder, and salt to the mix. Sprinkle sesame seeds and poppy seeds over the top of the buns before they bake.
Seasoning Option 2: Add the Everything Bagel Seasoning to the tops of the buns half-way through baking so they only bake for the second half of the bake time.
Step 1: Cook the Sweet Potatoes
Steaming Method: Peel and dice 1 sweet potato. Place a steamer basket in a sauce pan and fill it with water to the bottom of the basket. Place the diced sweet potatoes inside the basket, cover with the lid, and cook at medium heat for 20 minutes or until fork tender. Drain and allow the sweet potatoes to cool to room temperature.
Oven-Baked Method: Preheat the oven to 400°F (200°C). Wash and dry the sweet potato, then poke a few holes with a fork. Place it on a baking sheet and bake for 45-60 minutes, until a fork slides in easily. Let it cool slightly, then scoop out the soft insides to use in your recipe.
Place your cooked sweet potato in a bowl and mash with a potato masher or fork until smooth.
Preheat your oven to 375°F (190°C) and line a baking sheet with parchment paper.
Step 2: Shape and Bake the Buns
In a bowl, combine the mashed sweet potatoes, egg, shredded mozzarella, and salt. Mix until well combined.
Scoop out 4 portions of the mixture and shape them into bun-sized rounds roughly .25 inches thick on the baking sheet.
Seasoning Option 1: Lightly sprinkle coarse sea salt, sesame seeds and poppy seeds over the top of the buns.
Bake for 22-24 minutes or until the tops begin to brown.
Seasoning Option 2: Bake the buns for 10 minutes, remove from the oven, and sprinkle with Everything Bagel Seasoning. Then bake for an additional 12-14 minutes until the tops begin to brown.
Remove the bread from the oven and let it cool in the pan for 10 minutes. Then, transfer it to a wire rack to cool completely.
Bake in an air fryer: Divide the mixture into 4 portions and spread on a piece of parchment paper cut to the size of the air fryer basket. Bake at 400ºF for 10 minutes. Then carefully remove the parchment paper from the basket, flip the patties over with a spatula, lower the parchment paper and buns back into the air fryer, and bake for another 5 minutes or until golden brown.
Let the buns cool slightly before serving or slicing.
My Expert Recipe Tips
- Watch the sweet potato moisture: The mash should be thick and smooth, not loose or watery. Too much moisture is the main reason these buns spread or bake up soft.
- Shred cheese from a block if possible: Freshly shredded mozzarella melts more evenly and gives the buns better structure than pre-shredded cheese.
- Don’t skip the cooling time: These buns firm up slightly as they cool. Letting them rest before slicing helps them hold together better for sandwiches.
- Use the air fryer for reheating: If you’re reheating leftovers, the air fryer brings back the best texture. Microwaving tends to make them soft or gummy.
- Add seasoning halfway through baking: Especially with Everything Bagel Seasoning, this prevents burnt garlic or onion and keeps the flavor balanced.
Delicious Sweet Potato Bun Serving Suggestions
Use these sweet potato bread buns anywhere you’d normally reach for a sandwich bun or flatbread.
- Sandwich buns: Great with turkey, chicken, lettuce, tomato, and your favorite spreads.
- Burger buns: Hold up well for my smashed turkey burgers, ground chicken burgers, or veggie burgers once cooled.
- Mini flatbread pizzas: Add sauce and cheese, then bake until warm and bubbly.
- Breakfast buns: Use them in my McMuffin breakfast sandwiches or avocado cottage cheese toast.
- Simple sides: Serve alongside soup, fall harvest salad, or dips like my cottage cheese ranch.
