Sweet Potato Biscuits Recipe

Sweet potato biscuits are a Southern classic, but too many recipes turn out dense, gummy, and heavy. The culprit is almost always the sweet potato itself—its water content, and how you handle it. Get that right and you’re rewarded with tall, tender, golden biscuits.

Roasting instead of boiling is the game-changer. It concentrates the natural sugars and drives off excess moisture, so the dough stays workable instead of turning into a sticky, soggy mess. That one switch fixes most of what goes wrong.

The rest is classic biscuit discipline: cold butter, cold buttermilk, a light hand, and a brief chill before baking. Do that and you’ll get soft, fluffy layers with a gentle sweetness that belongs on every holiday table.

The Secret to Great Sweet Potato Biscuits

Roasting the sweet potato concentrates its sugars and removes water, so the dough never turns wet or gummy. That’s the single biggest fix for heavy biscuits.

Chilling the dough re-solidifies the butter. As those cold flecks melt in a hot oven, they push steam upward and create flaky layers.

Folding the dough a few times builds structure without overworking the gluten. That’s how you get tall, tender biscuits instead of flat, tough ones.

Servings: 8 | Prep time: 15 minutes | Cook time: 12 minutes | Total time: 1 hour 15 minutes (includes roasting and chilling)

Ingredients

• 2 cups all-purpose flour, plus more for dusting
• 1 tablespoon baking powder
• 1 teaspoon salt
• 1/2 teaspoon baking soda
• 1/4 cup granulated sugar
• 1/2 cup (1 stick) unsalted butter, cold, cut into cubes
• 1 cup mashed roasted sweet potato, cooled
• 3/4 cup buttermilk, cold

Instructions

1. Roast the sweet potato: Preheat oven to 400°F (200°C). Prick a medium sweet potato (about 8 ounces) all over with a fork. Roast directly on the oven rack until very tender, about 45-50 minutes. Let cool, then scoop out the flesh and mash until smooth. Measure 1 cup; save any extra for another use.
2. Combine dry ingredients: In a large bowl, whisk together 2 cups flour, 1 tablespoon baking powder, 1 teaspoon salt, 1/2 teaspoon baking soda, and 1/4 cup sugar.
3. Cut in the butter: Add the cold butter cubes to the dry ingredients. Use a pastry blender or your fingertips to cut the butter in until the mixture resembles coarse meal with some pea-sized butter lumps. Work quickly to keep the butter cold.

4. Add sweet potato and buttermilk: In a small bowl, whisk together the mashed sweet potato and buttermilk until smooth. Pour into the dry ingredients and stir with a fork until just combined. The dough will be sticky.
5. Fold and chill: Turn the dough out onto a well-floured surface. With floured hands, gently fold the dough over itself 3-4 times, adding flour as needed to prevent sticking. Pat into a 1-inch-thick rectangle. Wrap in plastic and refrigerate for at least 30 minutes (or up to 24 hours).
6. Cut and bake: Preheat oven to 425°F (220°C). Line a baking sheet with parchment paper. On a floured surface, pat the chilled dough to 1-inch thickness. Cut with a floured 2.5-inch biscuit cutter, pressing straight down without twisting. Place biscuits 2 inches apart on the sheet. Gather scraps, re-pat, and cut again. Bake for 12-15 minutes, until golden brown on top and bottom.

Tips & Variations

• For extra flaky biscuits, freeze the butter and grate it using a box grater before cutting it into the flour.
• No buttermilk? Substitute 3/4 cup whole milk mixed with 1 tablespoon lemon juice or vinegar; let sit 5 minutes.
• Add 1/2 teaspoon cinnamon or pumpkin pie spice to the dry ingredients for a warm flavor.
• Fold in 1/2 cup chopped pecans or raisins for extra texture.
• For a savory version, reduce sugar to 1 tablespoon and add 1/2 cup shredded cheddar and 2 tablespoons chopped chives.
• Brush tops with melted butter right after baking for a soft, shiny crust.
• Avoid twisting the biscuit cutter; twisting seals the edges and prevents rise.

Storage & Make-Ahead

Store baked biscuits in an airtight container at room temperature for up to 2 days, or in the refrigerator for up to 5 days. Reheat in a 350°F oven for 5-7 minutes.

To freeze, wrap baked biscuits tightly and freeze for up to 2 months; thaw at room temperature and reheat. Unbaked cut biscuits can be frozen on a sheet, then transferred to a bag; bake from frozen, adding 2-3 minutes to baking time.

Questions About Sweet Potato Biscuits

Can I use canned sweet potato puree instead of roasting?

Yes, but roasted fresh sweet potato gives a deeper flavor and better texture. If using canned, make sure it’s pure pumpkin or sweet potato puree, not pie filling, and drain any excess liquid. You may need a bit more flour if the dough is too wet.

Why are my sweet potato biscuits dense?

Dense biscuits usually come from overworking the dough or using warm ingredients. Keep everything cold, handle the dough gently, and avoid adding too much flour. Also, make sure your baking powder is fresh.

Can I make these biscuits ahead of time?

Yes. Prepare the dough, cut the biscuits, and refrigerate them on a baking sheet for up to 24 hours before baking. You can also freeze unbaked biscuits and bake them straight from the freezer.

What can I substitute for buttermilk?

Mix 3/4 cup milk with 1 tablespoon lemon juice or white vinegar and let it sit for 5 minutes until slightly curdled. Plain yogurt thinned with milk also works well.

How do I get tall, flaky biscuits?

Use cold butter and cold buttermilk, handle the dough minimally, and fold it a few times to create layers. Cut with a sharp cutter pressed straight down, and bake in a hot 425°F oven.

Can I use this recipe to make drop biscuits?

Yes—increase the buttermilk to 1 cup for a wetter dough, then drop spoonfuls onto a baking sheet and bake as directed, adding a few minutes if needed.
