- Sweet Potato Sourdough Biscuits Recipe
This recipe was developed using Bako Sweet® sweet potatoes! Their sweet potatoes are California-grown using sustainable farming practices that care for the land. They are meticulously hand-selected by seasoned farmers, tripled-washed, and conveniently bagged, ensuring they arrive on our tables in prime condition. This diligent quality control is probably why each sweet potato I used to test this recipe was the perfect size for a batch of these sourdough biscuits!
Why add sweet potatoes to biscuits?
Not only do sweet potatoes lend a vibrant orange hue to these delightful biscuits, but they also bring a host of advantages. Water locked inside sweet potatoes adds moisture to the dough without making it too difficult to handle. Moreover, they limit gluten formation, resulting in biscuits that are wonderfully soft and tender. And let's not forget the natural sweetness they infuse into every bite of the biscuits, while also providing a nutritious boost of potassium, fiber and vitamins C and A.
You can even add sweet potatoes to yeast bread, like my pillowy, soft Sweet Potato Sourdough Discard Bread.
Why I love this recipe
- Tender and sweet thanks to Bako Sweet® Organic Orange Sweet Potatoes.
- Buttery flavor with a melt-in-your-mouth texture.
- Show-stopping orange hue.
- Mixed by hand, no stand mixer required!
- Easy recipe that can be made in advance.
- Versatile quick bread that tastes great with sweet and savory toppings.
What is quick bread?
Quick breads use baking soda and baking powder to help them rise, unlike bread that uses commercial yeast or sourdough starter. These breads don’t require a rise time, hence are much faster to make.
If you’ve been following the blog for a while, you’re probably already familiar with my obsession with sourdough quick bread. I love having recipes like my Sourdough Discard Biscuits, and Sourdough Scones, in my back pocket for times when I want to serve fresh baked goods but don't have time to prepare a Basic Sourdough Loaf. These Sourdough Sweet Potato Biscuits were a natural addition to my quick bread collection!
Check the expiration date on your baking powder and baking soda
Chemical leaveners have a shelf life and will eventually lose their leavening abilities. To test if yours will work, drop a pinch in a small amount of vinegar. If it fizzes then your baking powder and baking soda is good to go.
What you need
Bako Sweet® Organic Orange Sweet Potatoes: This recipe uses one medium-sized sweet potato (240-250 grams). There’s no substitute for this ingredient.
All-purpose flour: The low protein content imparts softness and lightness to these biscuits, don’t substitute bread flour or whole wheat flour or they will be too dense.
Cane sugar: Adds sweetness and helps with browning, skip if you don’t want added sugars.
Buttermilk: Reacts with baking soda to enhance the tender texture of these biscuits, if you don’t have any on hand substitute whole milk and add ¼ teaspoon of apple cider vinegar to the recipe.

For tender, flaky biscuits start with cold ingredients. This will prevent your dough from becoming too warm and the butter from melting before your biscuits are baked.

Baking with sourdough discard
The addition of sourdough discard contributes a rich and nuanced flavor to these biscuits. Since the sourdough starter is used solely for flavor enhancement, there's no need to activate it; you can use it directly from the refrigerator.
Using sourdough discard that has been in the refrigerator for some time will impart a more tangy, intense flavor. This provides distinct results compared to a freshly fed starter. However, both options work well in this recipe.
Why roasted sweet potatoes are better
- Caramelizes natural sugars, creating a richer, sweeter taste compared to boiling or steaming methods.
- Develop complex, savory notes through browning reactions, adding depth to the overall flavor profile of your biscuits.
- Helps prevent additional water from being added to the dough. Excess water can lead to biscuits becoming tough and gummy in texture
How to Make Sweet Potato Sourdough Biscuits
STEP 1: Roast the sweet potatoes
Place 1 sweet potato on a parchment-lined baking sheet. Poke holes all over the sweet potato using a fork (image 1). Roast the sweet potato for 40 to 50 minutes or until the skin is puffy and the center is soft (image 2). Make sure the sweet potato is completely cool before adding it to your dough or it may cause the butter in the dough to melt.
You can prepare the sweet potato by roasting it up to 2 days ahead to save on prep time.
STEP 2: Make the dough
Puree the sweet potato, sourdough discard, and buttermilk (image 3). Whisk the dry ingredients together and rub the butter in until pea-sized pieces form (image 4). Make a hole in the center of the flour mixture and pour the sweet potato puree in (image 5). Stir the mixture until most of the flour has been hydrated, and lightly knead the dough two to three times until a cohesive dough forms (image 6).
Your dough should be slightly sticky with only a few traces of dry flour. Do your best to make sure it’s not completely crumbly, but don’t overwork the dough.
STEP 3: Laminate the dough
Turn the dough out onto a heavily floured surface. Using floured hands, flatten the dough into a large rectangle, the size doesn’t have to be exact (image 7). Divide the dough into 3 portions and stack them on top of each other (image 8). Repeat once more.
Laminating creates buttery layers within the dough. During baking, the trapped water in the butter evaporates, producing steam that causes them to rise and puff up. It's an additional step that results in sky-high biscuits with a delicate, tender texture.
STEP 4: Shape the dough
Flatten the dough into a 5 by 8-inch rectangle, about ½-inch in thickness (image 9). Use a 2-inch biscuit cutter to cut out 6 portions (image 10). Re-roll the dough and cut out 2 to 3 more portions.
Avoid twisting the biscuit cutter when cutting the dough, this will seal the edges and prevent the biscuits from puffing up and flaky layers from forming. If you don’t have a biscuit cutter, simply use a knife to trim the edges and cut out 2-inch square portions.
STEP 5: Bake
Place the dough on a baking sheet lined with parchment. Brush with buttermilk (image 11). Bake at 400 F for 20 to 25 minutes or until the tops are golden brown (image 12).
Baker's Tips
- Weigh your ingredients. Measuring by weight is much more accurate than by volume (with tablespoons and cups).
- Sourdough discard and active starter both work for this recipe
- Use buttermilk, it's a byproduct of the butter-making process, is naturally acidic and reacts with baking powder to help scones rise higher resulting in softer tender biscuits.
- If the butter starts to melt and the dough starts feeling sticky, don’t be afraid to wrap it up and refrigerate for a few minutes to let the butter solidify and the flour to hydrate.
- Bake at high temperature. High oven temperatures causes the water locked in butter to turn into steam as the scones bake. This creates steam and pockets of air in the dough leading to soft, tall, tender biscuits.
Make ahead instructions
Prep the sweet potatoes in advance
- Sweet potatoes can be roasted at least 2 days in advance to cut down prep time.
- Store roasted sweet potatoes in the refrigerator in an airtight container until ready to use.
To freeze biscuit dough
- Cut out the biscuit portions
- Arrange your biscuits side-by-side on a parchment-lined baking sheet (no need to space them out)
- Freeze the tray uncovered for at least 1 hour.
- Transfer the frozen biscuit dough to an airtight container or a freezer bag.
- Store frozen biscuits in the freezer for up to 3 months.
To bake frozen biscuits
- Preheat the oven to 375 F.
- Arrange biscuits at least 1-inch apart on a baking sheet lined with parchment paper.
- Brush the top of the dough with melted butter and milk (or buttermilk).
- Bake the biscuits for 25 to 30 minutes or until golden brown.
What to serve with Sweet Potato Sourdough Biscuits
These biscuits have a slightly sweet, earthy flavor thanks to roasted sweet potatoes. They would be great as a base for a breakfast sandwich, a scoop of sausage gravy and even complement the sweetness of strawberry shortcakes.
I love them on their own or slathered with Honey Butter or Cultured Butter and topped with homemade Blueberry Preserves or Raspberry Preserves.
Recipe FAQs
Sourdough discard is any portion of your starter removed during the feeding process or any part not used to leaven sourdough bread. You can use it in other bakes and dishes or store it in the refrigerator.
There are a few reasons:
1. Your leaveners may be expired
2. The butter in the dough became too warm and melted out of your dough
3. You didn't knead your dough enough. Although biscuits need a light hand, if you don't develop enough gluten, your dough may not be able to rise.
No, biological leaveners such as sourdough starters require a combination of time and gluten development to make baked goods rise. As yeast ferments, it releases CO2 which gets trapped by strong gluten networks in the dough. Gluten development will negatively affect the texture of your biscuits.
