In this post, we’ll walk through how to make sourdough blueberry bagels step by step, from mixing the dough to that classic chewy boil.
 
Let’s dive in.
 

How to Make Sourdough Blueberry Bagels: The Basic Process

Learning how to make sourdough blueberry bagels starts with understanding the dough.
 
Bagel dough is stiff and low in hydration compared to regular bread dough.
 
That stiffness is what gives bagels their signature chew.
 
When you make sourdough blueberry bagels, you’re basically combining flour, water, salt, a bit of sweetener, your active sourdough starter, and fresh or frozen blueberries.
 
The blueberries add moisture, so you may need to adjust the flour slightly.
 
The process goes like this: mix, knead, bulk ferment, shape, cold proof, boil, and bake.
 
It sounds long, but most of that time is hands-off.
 
The sourdough does the heavy lifting while you go about your day.
 

1. Mixing and Kneading the Dough

To make sourdough blueberry bagels, start by combining your starter, water, and a little honey or barley malt syrup in a bowl.
 
Add bread flour and salt, then mix until a shaggy dough forms.
 
Knead for about 8 to 10 minutes until the dough is smooth and elastic.
 
Fresh blueberries should be folded in gently at the end so they don’t get crushed.
 
If you’re using frozen blueberries, toss them in a little flour first to keep them from bleeding too much color into the dough.
 

2. Bulk Fermentation and Shaping

Once your dough is kneaded, cover it and let it rise at room temperature until it’s about 50 to 75 percent bigger.
 
This can take 4 to 8 hours depending on how warm your kitchen is and how active your starter is.
 
After the bulk rise, divide the dough into equal pieces and shape each one into a tight ball.
 
Poke a hole through the center with your thumb and stretch it gently to form the bagel shape.
 
Place the shaped bagels on a parchment-lined baking sheet.
 

3. Cold Proofing Overnight

This is the step that makes sourdough blueberry bagels taste so good.
 
Cover the shaped bagels and stick them in the fridge for 12 to 24 hours.
 
The long cold proof develops flavor and makes the bagels easier to handle the next day.
 
It also helps the blueberries settle into the dough so they don’t all fall out during boiling.
 

Boiling and Baking Your Sourdough Blueberry Bagels

The boil is what sets bagels apart from regular bread.
 
When you make sourdough blueberry bagels, you’ll bring a large pot of water to a boil and add a tablespoon of honey or malt syrup.
 
Drop each bagel into the boiling water for about 30 seconds per side.
 
This gelatinizes the outside of the dough and creates that shiny, chewy crust.
 

1. Add a Little Baking Soda

Some bakers add a pinch of baking soda to the boiling water for extra browning.
 
It’s optional, but it gives your sourdough blueberry bagels a deeper golden color.
 
Just don’t overdo it or you’ll taste the soda in the final bagel.
 

2. Bake at High Heat

After boiling, transfer the bagels back to the baking sheet.
 
Bake them at 425°F for about 20 to 25 minutes, flipping once halfway through if you want even browning.
 
The bagels are done when they’re golden on the outside and sound hollow when you tap the bottom.
 
Let them cool on a wire rack before slicing.
 

Tips for Perfect Sourdough Blueberry Bagels Every Time

Making sourdough blueberry bagels gets easier with practice, but these tips will help you nail it from the start.
 

1. Use a Active Starter

Your starter should be bubbly and doubled in size before you mix the dough.
 
If it’s sluggish, your bagels will be dense and flat.
 
Feed it the night before you plan to make sourdough blueberry bagels for the best results.
 

2. Don’t Skip the Cold Proof

The overnight rest in the fridge is non-negotiable if you want that classic sourdough tang.
 
It also makes the dough much easier to work with the next morning.
 

3. Handle the Blueberries Gently

Fresh blueberries can burst easily, so fold them in with a light hand.
 
If you want a more uniform purple color throughout your sourdough blueberry bagels, mash a few berries before adding them.
 

So, How to Make Sourdough Blueberry Bagels?

You can make sourdough blueberry bagels by mixing a stiff dough with your starter and blueberries, letting it ferment, shaping, cold proofing, boiling, and baking.
 
The process takes time, but most of it is waiting, not working.
 
And the payoff is a batch of chewy, tangy, fruity bagels that beat anything from the grocery store.
