The Best Sweet Potato Biscuits Recipe (2024)

Why It Works

  • Sweet potato purée provides hydration while keeping the dough thick and easy to handle, and the biscuits light and moist.
  • Folding the dough creates layers and structure, for pull-apart biscuits sturdy enough for a breakfast sandwich.
  • Baking on cast iron ensures the biscuits are crisp along the bottom.

I've been on something of a biscuit kick, with the classic buttermilk biscuits in my cookbook, a yogurt-based alternative here on Serious Eats, and even an angelic variation made with plain milk, yeast, and an overnight rise. That's because biscuits aren't about having one be-all, end-all recipe, so much as having an arsenal of recipes that fit a variety of occasions. And sweet potato biscuits are certainly the most fun and colorful option of all.

The Best Sweet Potato Biscuits Recipe (1)

The classic recipe is the result of Southern thrift and ingenuity, allowing a cheap and sturdy root vegetable to take the place of something more perishable like milk; sweet potato purée also helped make up for the lack of browning that can sometimes plague biscuits made with non-dairy fats like shortening or lard. So far as I can tell, the goal wasn't to create a new flavor of biscuit so much as a new path to a familiar goal: a tender, light, and fluffy accompaniment to any meal.

Preparing the Sweet Potato

To get started, you'll need some sweet potato purée. How you acquire it hardly matters; boil a sweet potato up for the occasion, toss one in the microwave, roast one 'til fork tender, raid the fridge for leftovers, whatever! At home, I tend to make sweet potato biscuits after I've roasted one too many sweet potatoes for dinner the night before.

However you go about cooking it, squeeze the tender sweet potato from its jacket, and mash the flesh with milk or water in a bowl; this loosens up the purée so the dough isn't too stiff down the road, which could inhibit its rise. Blitz the sweet potato and liquid with an immersion blender until silky smooth, or mash the mixture with a fork for a more rustic presentation that will leave bits of sweet potato flecked throughout the dough (my personal favorite).

This step can be done at the last minute, or the thinned purée can be held in the fridge up to a week in advance—a nice make-ahead option if you're so inclined.

Making the Biscuits

The dry mix for these biscuits will be prepared with the same method I use for plain, homemade biscuits as well as angel biscuits, with chunks of cold butter roughly incorporated into the dry mix, then hydrated with a liquid—in this case, that thinned sweet potato purée.

Like cultured buttermilk or yogurt, sweet potato purée is thick enough that a ton of the stuff can be incorporated into a dough without turning it into a sticky mess. In fact, the mixture may seem crumbly and dry at first; resist the temptation to add any extra liquid and simply keep kneading until the dough comes together and no flour is left at the bottom of the bowl.

Once the flour is fully incorporated, it pays to use a gentler touch. As with my other biscuit recipes, I turn the dough onto a lightly floured surface where I pat it out, fold it in half, and repeat the process two more times, for a total of three folds.

It's a gentle way of handling the dough, more quantifiable than kneading when it comes to developing enough gluten to hold the biscuits together, and smarter, too, since folding develops layers within the dough. In turn, those layers provide a natural fault line for splitting the baked biscuits in half, so they'll be easy to sandwich around anything from fried eggs to country ham. If you have trouble visualizing the process, the method for my yogurt biscuits is exactly the same, even if the dough looks rather different.

After the last turn, pat out the dough until it's about three-quarters of an inch thick, then cut into one-and-three-quarter-inch rounds (or whatever size you like; just bear in mind that the yield will vary).

Transfer the cutouts to a 10-inch cast iron skillet, and bake at 400°F until puffed and golden brown, about 30 minutes.

You can brush the biscuits with butter if you like, but I usually skip this step since it encourages more browning, making it harder to judge when the ochre-colored biscuits are done. And besides, these biscuits bake up plenty rich and buttery all on their own.

As with any biscuit, give these about five minutes to rest before serving. It's hard to wait, but fresh from the oven, the biscuits will be soft and easily compressed, making them seem gummy and dense. It only takes a few minutes for their crumb to set, and the result is a light and airy biscuit that'll still be plenty warm thanks to the insulation of cast iron.

Whether you're drawn to the recipe for its lack of buttermilk or the bright pop of color, sweet potato biscuits are a welcome addition to any meal, and just as delicious as they are beautiful to behold.

The Best Sweet Potato Biscuits

Active20 mins

Total45 mins

Serves14 servings

Ingredients

  • 9 ounces all-purpose flour, such as Gold Medal (about 2 cups, spooned; 255g)

  • 1 tablespoon baking powder

  • 2 teaspoons (8g) Diamond Crystal kosher salt; for table salt, use about half as much by volume or the same weight

  • 1/2 teaspoon baking soda

  • 4 ounces cold, unsalted butter, cut into 1/2-inch cubes (about 8 tablespoons; 110g)

  • 9 ounces sweet potato purée, from one large sweet potato, see notes (about 1 heaping cup; 255g)

  • 3 ounces milk, any percentage will do (about 1/3 cup plus 1 tablespoon; 85g)

Directions

  1. Adjust oven rack to lower-middle position and preheat to 400°F. Should your kitchen be warmer than 75°F, please see our guide to baking in a hot kitchen before getting started; the specifics are focused on pie dough, but the overall principles are true of biscuits as well.

  2. Sift flour, baking powder, baking soda, and salt into a medium bowl, then whisk until well combined (this may take up to 1 minute). Add the butter, toss to break up the pieces, and smash each cube flat. Continue smashing and rubbing until the butter has mostly disappeared into a floury mix, although a few larger, Cheerio-sized pieces may remain. This can also be done with 4 or 5 pulses in a food processor, just take care not to overdo it. The prepared mix can be refrigerated up to 3 weeks in an airtight container, then used as directed below.

  3. Mash the sweet potato purée and milk together with a fork, or combine with an immersion blender until perfectly smooth. Add to the dry mix in a large bowl, and fold with a flexible spatula until fully absorbed. The dough will seem rather crumbly and dry at first, but keep mixing until it finally comes together. Once the dough forms a rough ball, turn out onto a lightly floured surface.

  4. With your bare hands, gently pat the dough into a squarish shape about 1/2-inch thick, then fold in half; repeat twice more for a total of 3 folds, using only enough flour to keep your hands from sticking. Finish by patting the dough to a thickness of 3/4 inch. If needed, dust away any excess flour, then cut into 1 3/4-inch rounds and arrange in a 10-inch cast iron skillet. Gather scraps into a ball, pat and fold a single time, then cut as many more biscuits as you can. The final round of scraps can be gathered and shaped into a single biscuit by hand.

  5. Bake until the biscuits are well-risen and golden brown, about 25 minutes (or longer if cut thicker than 3/4-inch). Let the biscuits cool about 5 minutes to help set their crumb, then serve as desired, whether alongside soups and stews or split for shortcake or breakfast sandwiches. Leftovers can be stored up to a week in an airtight container; to serve, split the stale biscuits in half, brush with melted butter, arrange on a baking sheet, and broil until golden brown, then serve with jam.

FAQs

Is it better to use butter or Crisco for biscuits? ›

The butter version rises the highest — look at those flaky layers! The shortening biscuit is slightly shorter and a bit drier, too. Butter contains a bit of water, which helps create steam and gives baked goods a boost.

What is the secret to biscuits? ›

Use Cold Butter for Biscuits

When the biscuit bakes, the butter will melt, releasing steam and creating pockets of air. This makes the biscuits airy and flaky on the inside.

What makes biscuits taste better? ›

A word of advice: Start with good ingredients. Biscuits, like many breads, only use a few ingredients so you'll really taste each one. Choosing good-quality butter, milk, and flour will pay off in the flavor of the end result.

What makes biscuits rise and fluffy? ›

Fully incorporating the butter and flour guarantees tender, airy biscuits every time. Low-protein flours keep biscuits fluffy and light, never tough. Yogurt provides both hydration and structure, for biscuits that bake up straight and tall but moist.

What kind of liquid is best for making biscuits? ›

Milk or Buttermilk: I love how this recipe works with milk or buttermilk. If you love the tangy flavor of buttermilk, use it.

Which fat makes the best biscuits? ›

In terms of flakiness, the best fat for making biscuits is probably lard, and vegetable shortening is the next best. In terms of flavor, however, butter is undoubtedly the best, with lard a close second.

What type of flour makes the best biscuits? ›

The Bottom Line

I personally think that biscuits are at their best when you use a fine pastry-type flour like White Lily or Bob's Pastry flour. BUT, all-purpose flour is absolutely an option. I actually think that your technique when making biscuits is just as - if not, more - important than the flour you use.

What is the secret to high rising biscuits? ›

Cut off uneven edges and put these scraps to the side; clean cuts on all sides will encourage rise. Pat scraps together to make 1 odd-shaped ninth biscuit. Place biscuits close together in a 9-inch square pan and brush with melted salted butter. Place pan on top of the warm stove for 10 to 15 minutes to rise.

What kind of flour do Southerners use for biscuits? ›

White Lily brand flour, especially the self-rising flour, is the gold standard among Southern cooks who make biscuits on a regular basis. White lily, self rising. I use it for everything except those thing I make using either cake flour or yeast.

Is it better to use milk or buttermilk in biscuits? ›

Buttermilk adds a nice tang to the biscuit flavor and helps them rise better.

Should you let biscuit dough rest? ›

Cover the dough loosely with a kitchen towel and allow it to rest for 30 minutes. Gently pat out the dough some more, so that the rectangle is roughly 10 inches by 6 inches. Cut dough into biscuits using a floured biscuit cutter (or even a glass, though its duller edge may result in slightly less tall biscuits).

How can I get my biscuits to rise higher? ›

Bake them close to each other.

Biscuits are an exception to this rule: Placing them close to one another on your baking sheet actually helps them push each other up, as they impede each other from spreading outward and instead puff up skywards.

Do you use baking soda or baking powder for biscuits? ›

But to get the rise you want without killing the tang (which would be the result of too much baking soda), you'll need to incorporate baking powder as well, taking advantage of the delayed double-action to add even more levity. Combining the two leavening agents produces a biscuit that is both light and tangy.

Is shortening better for biscuits? ›

Shortening is more effective at reducing gluten formation in doughs. Indeed, this is where the name comes from — it “shortens” gluten strands. It also has a higher melting point than butter, making it less likely to smear into biscuit dough, even if you use your hands to mix it.

Is Crisco better than butter? ›

Additionally, shortening is high in calories and offers no nutritional benefits. Therefore, it's a good idea to limit your intake of shortening and use healthier alternatives when possible — like butter, olive oil, avocado oil, or coconut oil.

What happens if you use butter instead of shortening? ›

You'll notice these differences if baking with butter instead of shortening. Cookies made with butter or margarine may be softer and spread a little more. Cookies made with butter are usually crispier than chewy cookies made with shortening, but the flavor is richer with butter.

Why is shortening good for biscuits? ›

The fat that is in shortening melts above room temperature and then seeps into the dough, creating a physical barrier between all the gluten molecules, causing them to not expand as much. Shortening can also be used to keep your baked goods soft after baking.
