Vegan Sweet Potato Biscuits: A Taste of Southern Comfort

There’s a certain magic to a warm, fluffy biscuit, especially one tinged with the subtle sweetness of sweet potato. I remember one Thanksgiving years ago, feeling adventurous, I decided to stir a bit of leftover roasted sweet potato into my usual biscuit dough. The results were surprisingly delightful – a vibrant orange hue, a delicate sweetness, and a tender crumb that practically melted in your mouth. From that day on, sweet potato biscuits have earned a permanent place on my holiday (and everyday) baking roster. These vegan sweet potato biscuits offer all the comforting flavors of the traditional recipe without any animal products.

Recipe Overview

• Prep Time: 25 minutes
• Cook Time: 1 hour 26 minutes
• Total Time: 1 hour 51 minutes
• Servings: 12
• Yield: 12 biscuits
• Dietary Type: Vegan

Ingredients

• 1 medium sweet potato
• 1 1/4 cups soy milk
• 1 tablespoon vinegar
• 2 1/2 cups unbleached all-purpose flour
• 1 cup cake flour
• 5 teaspoons baking powder
• 4 teaspoons vegan sugar or 4 teaspoons sugar substitute, of your choice
• 2/3 cup cold vegetable shortening, cut into small pieces
• 4 tablespoons cold vegan margarine, cut into small pieces (I like Earth Balance)

Equipment Needed

• Fork
• Oven
• Liquid measuring cup
• Food mill or large-mesh sieve
• Large bowl
• Whisk
• Pastry blender
• Floured surface
• Knife or cookie cutter
• Insulated baking sheet or doubled regular baking sheets

Instructions

1. Preheat your oven to 400°F (200°C).
2. Prick the sweet potato several times with a fork. This allows steam to escape and prevents explosions! Place the sweet potato directly on the oven rack and bake until very tender. This will take about 1 hour and 15 minutes. Check for doneness by piercing the potato with a fork; it should slide in easily.
3. Let the baked sweet potato cool completely. This step is crucial, as warm sweet potato will melt the fats in your dough, leading to tough biscuits.
4. Position an oven rack in the top 1/3 of the oven and preheat the oven to 450°F (230°C). A hot oven is key for achieving a good rise and golden-brown tops.
5. Prepare the soured soy milk by adding the vinegar to a liquid measuring cup. Then, add the soy milk to the vinegar. The mixture will begin to curdle, mimicking the effect of buttermilk.
6. Peel the cooled sweet potato. Force it through the medium disk of a food mill, or a large-mesh sieve into a bowl. This ensures a smooth and lump-free sweet potato puree.
7. Add the soured soy milk to the pureed sweet potato and whisk until the mixture is smooth and well combined.
8. In a large bowl, sift together the all-purpose flour, cake flour, baking powder, and vegan sugar. Sifting ensures that the dry ingredients are evenly distributed and prevents lumps of baking powder from forming. If using a liquid sugar substitute, add it to the wet mixture instead.
9. Add the cold vegetable shortening and cold vegan margarine to the dry ingredients. Use a pastry blender to cut the fats into the flour mixture until the mixture resembles coarse corn kernels. Working quickly and keeping the fats cold is essential for creating flaky biscuits.
10. Add the sweet potato and soy milk mixture to the flour mixture. Stir until a soft, crumbly dough forms. Be careful not to overmix, as this will develop the gluten in the flour and result in tough biscuits.
11. Turn the dough out onto a well-floured surface. Gently knead the dough 8 to 10 times, or until it just holds together. Again, avoid overworking the dough.
12. Roll out and pat the dough into a rectangle measuring approximately 6 by 12 inches.
13. Using a knife or cookie cutter, cut the dough into 12 rectangular biscuits. Cutting the biscuits into rectangles minimizes dough scraps, which would need to be rerolled. Rerolling can lead to tougher biscuits.
14. Transfer the biscuits to an ungreased insulated baking sheet (recommended) or doubled regular baking sheets. Using an insulated baking sheet helps prevent the bottoms of the biscuits from burning.
15. Bake until the biscuits have risen and their edges and bottoms are lightly browned. This will take approximately 12 to 14 minutes. Check for doneness by inserting a toothpick into the center of a biscuit; it should come out clean.

Expert Tips & Tricks

• Keep it Cold: The secret to flaky biscuits lies in keeping the fats (shortening and margarine) as cold as possible. Consider chilling the dry ingredients bowl and pastry blender beforehand. You can even dice the vegan butter/margarine and shortening, then place them back in the freezer for 5 minutes before incorporating.
• Don’t Overmix: Overmixing develops the gluten in the flour, leading to tough, dense biscuits. Mix until just combined.
• High Heat: The initial high oven temperature creates steam, which helps the biscuits rise quickly and develop a light, airy texture.
• Rest the Dough: If you have time, wrap the dough in plastic wrap and chill it for 30 minutes before rolling it out. This allows the gluten to relax, resulting in more tender biscuits.
• Brush with vegan milk or melted butter for golden brown tops.

Serving & Storage Suggestions

These sweet potato biscuits are delicious served warm, straight from the oven. They pair perfectly with vegan butter, jam, or even a savory gravy.

• Room Temperature: Store leftover biscuits in an airtight container at room temperature for up to 2 days.
• Refrigerator: For longer storage, keep them in the refrigerator for up to 5 days.
• Freezer: To freeze, wrap the biscuits individually in plastic wrap and then place them in a freezer bag. They can be frozen for up to 2 months.
• Reheating: To reheat, bake the biscuits in a preheated oven at 350°F (175°C) for 5-10 minutes, or until warmed through. You can also microwave them for a shorter time, but they may become slightly softer.

Variations & Substitutions

• Gluten-Free: Substitute the all-purpose flour and cake flour with a gluten-free all-purpose blend. Be sure to use a blend that contains xanthan gum for binding.
• Spice it Up: Add a pinch of cinnamon, nutmeg, or ginger to the dry ingredients for a warming flavor.
• Herbaceous: Stir in some chopped fresh rosemary or thyme for a savory twist.
• Sweetener: Substitute the vegan sugar with maple syrup or agave nectar, adjusting the liquid accordingly.
• Different Plant Milk: Try almond, oat, or cashew milk instead of soy milk.
• Sweet Potato Variety: While any sweet potato will work, Beauregard sweet potatoes have a particularly vibrant color and sweet flavor.

FAQs (Frequently Asked Questions)

Q: Why do I need to use both all-purpose flour and cake flour?
A: Cake flour has a lower protein content than all-purpose flour, which results in a more tender crumb. Using both flours creates the perfect balance of structure and tenderness.

Q: Can I make the dough ahead of time?
A: Yes! You can prepare the dough up to 24 hours in advance. Wrap it tightly in plastic wrap and refrigerate. Let it sit at room temperature for about 15 minutes before rolling it out.

Q: My biscuits are tough. What did I do wrong?
A: Overmixing the dough is the most common cause of tough biscuits. Be careful not to overwork the dough when mixing the wet and dry ingredients.

Q: Can I use a different vegan butter substitute?
A: Yes, any vegan butter substitute will work. Just make sure it’s cold!

Q: My sweet potatoes are small; can I use more than one?
A: Yes, aim for around 1 cup of mashed sweet potato. You may need to adjust the amount of soy milk slightly to achieve the desired dough consistency.
