Sourdough Discard Biscuits

You won’t believe the flaky, buttery layers in these Sourdough Discard Biscuits. These homemade biscuits are so simple to make and are made so much better with a little tang from sourdough discard. 

This is the biscuit recipe I’ve been searching for my entire life. Before making these, I thought the perfect biscuits could only come from a can. Flaky with layers upon layers of buttery, rich crumb and a slight sourdough tang, you won’t believe how easy they are to make! I promise after you make these Sourdough Biscuits, you’ll come up with an excuse to eat biscuits every day. 

Baking with your sourdough discard

Biscuits are a type of quick bread leavened using chemical leaveners (baking soda and baking powder) instead of biological leaveners (commercial yeast or sourdough). Because you won’t be using your sourdough to make these biscuits rise you can bake with your sourdough discard straight from the refrigerator without activating or feeding it first.

What you’ll need

Sourdough Biscuit Ingredients

Sourdough discard – adds a lovely tang to the rich butteriness of these biscuits

Buttermilk – for super tender fluffy biscuits, always use buttermilk, the acidity reacts with the baking powder giving you pillowy soft biscuits that are out of this world! You can substitute milk in a pinch but your biscuits won’t be as tender.

Unsalted butter – imparts tons of flavor while the fat molecules coat the flour which prevents gluten development. As your biscuits bake, the water from the butter evaporates which creates hundreds of flaky layers. Remember to keep your butter cold!

All-purpose flour – all-purpose has the perfect amount of protein in it to create fluffy biscuits that maintain their structure, I would not recommend substituting whole wheat, but in a pinch you can use pastry or cake flour

Baking powder – main leavening agent that reacts with the buttermilk, it tenderizes the dough makes these biscuits rise and gives them a fluffy crumb

Baking soda – helps your biscuits brown better and balances the acidic flavors in the bake

Granulated sugar – adds a little bit of sweetness

Salt – brings out the flavor of the butter and discard

How to make flaky biscuit layers

To make hundreds of buttery, flaky layers, you’ll need to layer the biscuit dough by rolling, dividing and stacking the layers.

This creates multiple alternating layers of dough and butter, as your biscuits bake steam evaporates from the butter and the dough puffs up into delicious, tender, airy layers. 

Shaping your biscuits

For your biscuit layers to rise fully, you’ll need to trim the edges of your biscuit dough. You can use a biscuit cutter to shape your dough, but I prefer to cut mine into squares because it creates less waste. If you prefer round biscuits you can use a biscuit cutter and there is no need to trim the edges after you pat your dough down.

Description

You won’t believe the flaky, buttery layers in these Sourdough Discard Biscuits. These homemade biscuits are so simple to make and are made so much better with a little tang from sourdough discard. 


Ingredients

Scale

Dough

120 grams (½ cup) sourdough discard

180 grams (¾ cup) buttermilk (see note**)

226 grams (2 sticks) unsalted butter (cut into ½ inch pieces and chilled)

388 grams (3 ¼ cup) all-purpose flour

10 grams (2 ½ teaspoons) baking powder

2 grams (¼ teaspoon) baking soda

12 grams (2 teaspoons) granulated sugar

12 grams (2 teaspoons) salt 

Egg wash

28 grams (2 tbsp) milk

1 egg


Instructions

Prep: Line an 18 by 13 inch baking sheet with parchment paper. 

Make the dough: Stir your sourdough discard into the buttermilk until no traces of sourdough remain, set aside. 

In a large-sized mixing bowl, whisk together flour, baking powder, baking soda, sugar and salt.

Incorporate pieces of chilled butter into the flour mixture using your finger tips or a pastry cutter. You should end up with flour coated butter pieces of varying sizes.

Create a well in the center of the flour mixture, incorporate the milk mixture until all of the flour is hydrated. Lightly knead the dough in the bowl until the dough clumps together and most of the flour is hydrated (a few dry bits are ok, don’t overwork or your biscuits may turn out tough). 

Laminate the dough: Turn dough out onto a clean surface and pat into a 1 inch-thick square (you don’t have to be exact). Using a knife or bench scraper, cut dough into 4 pieces. Stack pieces on top of one another, sandwiching any loose dry bits of dough between layers, and press down to flatten. 

Shape the dough: Lift up dough with bench scraper and dust surface with flour. Roll dough into a 1-inch thick rectangle and trim a thin border around sides of dough to create clean edges. Cut into a 4×3 grid to make 12 biscuits.

Chill the dough: Preheat your oven to 425 F. Transfer biscuits to a parchment-lined baking sheet, spacing 2″ apart; freeze while your oven preheats, about 20 minutes.

Bake: Brush tops of biscuits with a mixture of milk and egg. Reduce oven temperature to 400 F and bake biscuits until deep golden brown on bottom and golden on top, 20–25 minutes.


Notes

Make ahead instructions: Unbaked biscuits can be frozen up to 1 month. Freeze, uncovered, on baking sheet until solid, then transfer to a resealable plastic bag. Do not thaw before baking, but add a few minutes to the baking time.

Buttermilk substitutions: you really can’t beat the texture that buttermilk imparts in these biscuits. However, if you don’t have any on hand, feel free to sub whole milk mixed with 14 grams (1 tbsp) of vinegar or lemon juice, or sour cream or yogurt thinned out with a little bit of milk.

    You can grate cold butter into the flour mix. Best pastry hack ever. No need to cut it in with a pastry cutter. Use the coarse side of the grater.

    1. Ooh great tip, Deb! I’m scheming on a 100% whole grain version of this recipe, I’ll try your method for that.

  2. Amanda says:

    These biscuits are delicious! I didn’t get quite the rise you did but plan to try again. I did notice you mention mixing sugar in but don’t have it listed in your ingredients. I’m also trying to print the recipe and can’t find a print version. Do you have a feature that allows me to print a 1-2 page copy of the recipe with a picture of the biscuits without all the extra details? When I print from this page it’s 3-4 pages long.

    1. Glad you enjoyed the biscuits! Are your raising agents fresh? Or did you use buttermilk? The reaction between the acids and basics in the recipe usually helps with the height in these biscuits. I’m sorry but I don’t currently have that feature!

  3. Heather says:

    Can I sub the buttermilk for yoghurt?

    1. You can, but you may have to add more of the thickness of yogurt in comparison to buttermilk. I’d add water a little bit at a time until your dough comes together 😁

  4. maggie says:

    I see comments about buttermilk but the recipe calls for whole milk. I am confused… I want to make these but have only 2% milk. Will that work or do I need whole milk or buttermilk?

    1. 2% should work fine!

      1. Maggie says:

        Thank you. Now how much sugar? Not in ingredient list but mentioned in the instructions

  5. Just updated the recipe! Thanks for pointing that out!
