If you’ve got a jar of sourdough starter hanging out in your fridge and a handful of blueberries just begging to be used, you’re about to meet your new favorite muffin.

It’s a genius way to cut down on waste and make something utterly delicious. These are perfect for lazy weekend mornings, school lunchboxes, or those afternoons when coffee needs a sweet companion.
And don’t worry, this isn’t one of those super fussy sourdough recipes. No proofing, no kneading, no drama. Just mix, bake, and enjoy warm, fluffy muffins in about 30 minutes. Whether you’re a sourdough newbie or a discard pro, this is the kind of recipe that’ll keep you coming back for more.

¾ cup (180ml) buttermilk or plain yogurt

1 ½ cups (225g) fresh or frozen blueberries

how to serve Sourdough Blueberry Muffins
Serve your Sourdough Blueberry Muffins warm or at room temperature. They are perfect on their own, or you can enjoy them with a pat of butter or a drizzle of honey. These muffins also go well with coffee or tea for a delightful breakfast or snack.
how to store Sourdough Blueberry Muffins
To keep your muffins fresh, store them in an airtight container at room temperature for up to 3 days. For longer storage, you can freeze the muffins. Wrap each muffin in plastic wrap and place them in a freezer bag. They can be frozen for up to 3 months. Thaw them at room temperature or warm them in the oven when you’re ready to enjoy.
tips to make Sourdough Blueberry Muffins
A. Use Discard or Active Starter
Discard: Great for adding tang and reducing waste. Ideal if you’re not looking for rise from the starter.
Active starter: Slightly boosts lift and adds a more complex flavor, especially if letting the batter ferment overnight.
B. Don’t Overmix the Batter
Mix just until the flour disappears. Overmixing leads to dense, tough muffins.
Gently fold in the blueberries to avoid smashing them.
C. Coat Blueberries in Flour
Toss blueberries in 1 tablespoon of flour before adding to the batter. This helps prevent them from sinking to the bottom.
D. Rest or Ferment the Batter (Optional)
For a deeper sourdough flavor and better digestibility, cover the mixed batter and rest it in the fridge overnight. Bake the next day.
E. Use Buttermilk or Yogurt
Adds moisture and balances sourdough’s tang with creaminess.
Greek yogurt or sour cream can also work well.
F. Use Room Temperature Ingredients
Eggs, milk, and butter should be at room temperature for a smoother batter and even baking.
G. Add a Crunchy Topping
Sprinkle coarse sugar, streusel, or oats on top before baking for a bakery-style look and extra texture.
H. Fill Muffin Cups Properly
Fill each cup about ¾ full. This gives a nice dome without overflowing.
I. Bake at High Heat First
Start at 425°F (218°C) for 5 minutes, then reduce to 350°F (175°C) to finish baking. This jumpstarts the rise and gives domed tops.
J. Cool on a Rack
Let muffins cool in the pan for 5–10 minutes, then transfer to a wire rack to avoid soggy bottoms.
variation
You can easily change up this recipe. Substitute blueberries with other fruits like raspberries, blackberries, or chopped bananas. To add some crunch, consider folding in nuts such as walnuts or pecans. You can also add a dash of cinnamon for a warm spice flavor.
