These buttermilk sourdough biscuits are a delightful twist on a classic recipe. The addition of sourdough starter gives them a unique tangy flavor, while the buttermilk ensures they are incredibly tender and flaky. Perfect for breakfast or as a side to any meal, these biscuits are sure to become a favorite in your household.
If you don't usually bake, you might not have buttermilk or a sourdough starter on hand. Buttermilk can be found in the dairy section of most supermarkets, and it adds a rich, tangy flavor to baked goods. A sourdough starter is a fermented mixture of flour and water, and you can either make your own or purchase it from a bakery or specialty store.
Ingredients For Buttermilk Sourdough Biscuits Recipe
All-purpose flour: The base of the biscuits, providing structure and texture.
Baking powder: A leavening agent that helps the biscuits rise and become fluffy.
Baking soda: Works with the buttermilk to create a tender crumb.
Salt: Enhances the flavor of the biscuits.
Butter: Adds richness and flakiness to the biscuits.
Buttermilk: Provides moisture and a tangy flavor.
Sourdough starter: Adds a unique tangy flavor and helps with the rise.
Technique Tip for Making Biscuits
When incorporating the cold butter into the flour mixture, make sure to work quickly to prevent the butter from melting. The goal is to create small, pea-sized pieces of butter throughout the dough. This will result in flaky layers in your biscuits. Using a pastry cutter or even your fingers, gently mix until the mixture resembles coarse crumbs. If the butter starts to soften, you can place the mixture in the refrigerator for a few minutes to firm it up before continuing.
Suggested Side Dishes
Alternative Ingredients
all-purpose flour - Substitute with whole wheat flour: Whole wheat flour adds a nutty flavor and more fiber, though it may make the biscuits denser.
baking powder - Substitute with cream of tartar and baking soda: Use ½ teaspoon cream of tartar and ¼ teaspoon baking soda for each teaspoon of baking powder to achieve a similar leavening effect.
baking soda - Substitute with additional baking powder: Use 3 teaspoon of baking powder for each teaspoon of baking soda, but note that this may slightly alter the taste.
salt - Substitute with sea salt: Sea salt can be used in the same quantity and will provide a similar flavor.
cold butter - Substitute with cold margarine: Margarine can be used in the same quantity and will provide a similar texture, though the flavor may differ slightly.
buttermilk - Substitute with milk and lemon juice or vinegar: Mix 1 cup of milk with 1 tablespoon of lemon juice or vinegar and let it sit for 5 minutes to create a similar acidity and texture.
sourdough starter - Substitute with yogurt: Use plain yogurt to provide a similar tangy flavor and moisture, though it won't contribute to the leavening as much as a sourdough starter.

How To Store or Freeze Your Biscuits
To keep your buttermilk sourdough biscuits fresh for a few days, store them in an airtight container at room temperature. This will help maintain their delightful texture and flavor.
If you want to enjoy the biscuits later in the week, consider refrigerating them. Place the biscuits in a resealable plastic bag or wrap them tightly in aluminum foil. They should stay fresh for up to a week.
For longer storage, freezing is an excellent option. First, let the biscuits cool completely. Then, wrap each biscuit individually in plastic wrap to prevent freezer burn. Place the wrapped biscuits in a resealable freezer bag or an airtight container. They can be stored in the freezer for up to three months.
When you’re ready to enjoy your frozen biscuits, preheat your oven to 350°F (175°C). Remove the biscuits from the freezer and unwrap them. Place them on a baking sheet and bake for about 10-15 minutes, or until they are heated through and slightly crispy on the outside.
If you prefer a quicker method, you can also reheat the biscuits in the microwave. Place a biscuit on a microwave-safe plate and cover it with a damp paper towel. Microwave on medium power for about 20-30 seconds, or until warmed through. Be cautious not to overheat, as this can make the biscuits tough.
For an extra touch of flavor, brush the tops of the reheated biscuits with melted butter or a drizzle of honey before serving. This will give them a fresh, bakery-like finish.
If you have leftover dough, you can freeze it before baking. Shape the dough into biscuits and place them on a baking sheet lined with parchment paper. Freeze until solid, then transfer the frozen dough to a resealable freezer bag. When you’re ready to bake, preheat the oven and bake the frozen dough directly, adding a few extra minutes to the baking time.
How To Reheat Leftovers
Oven Method: Preheat your oven to 350°F (175°C). Place the biscuits on a baking sheet and cover them with aluminum foil to prevent them from drying out. Heat for about 10-15 minutes or until they are warmed through.
Microwave Method: Wrap each biscuit in a damp paper towel to keep them moist. Microwave on medium power for 20-30 seconds. Check if they are warm enough; if not, continue to heat in 10-second intervals.
Toaster Oven Method: Preheat your toaster oven to 350°F (175°C). Place the biscuits on the rack or a baking sheet. Heat for about 10 minutes or until they are warmed through and slightly crispy on the outside.
Skillet Method: Heat a skillet over medium-low heat. Add a small amount of butter or olive oil to the skillet. Place the biscuits in the skillet and cover with a lid. Heat for about 2-3 minutes on each side or until they are warmed through.
Steam Method: Place a steaming basket over a pot of simmering water. Place the biscuits in the basket and cover with a lid. Steam for about 5 minutes or until they are warmed through. This method helps retain moisture in the biscuits.
Essential Tools for This Recipe
Oven: Preheat to 425°F (220°C) to bake the biscuits.
Large mixing bowl: Used to whisk together the dry ingredients and combine the dough.
Whisk: Helps to evenly mix the flour, baking powder, baking soda, and salt.
Pastry cutter: Cuts the cold butter into the flour mixture until it resembles coarse crumbs.
Measuring cups: Measures the flour, buttermilk, and sourdough starter accurately.
Measuring spoons: Measures the baking powder, baking soda, and salt accurately.
Floured surface: Provides a non-stick area to knead and pat the dough.
Round cutter: Cuts the dough into biscuit shapes.
Baking sheet: Holds the biscuits while they bake in the oven.
Cooling rack: Allows the biscuits to cool evenly after baking.
Time-Saving Tips for Making Biscuits
Prepare ingredients ahead: Measure and cut the butter in advance. Keep it in the fridge until needed.
Use a food processor: Quickly combine flour mixture and cold butter using a food processor instead of a pastry cutter.
Preheat the oven early: Start preheating your oven before you begin mixing the ingredients.
Keep tools handy: Have your pastry cutter, mixing bowl, and round cutter ready to go.
Batch preparation: Double the recipe and freeze extra biscuits for quick baking later.
