Yes, you absolutely do boil bagels in baking soda water, and it’s one of the most important steps for getting that signature chewy crust and glossy finish.
Boiling bagels in baking soda water is a classic technique that home bakers and pros alike swear by, because it gives the dough a quick bath that transforms its texture entirely.
If you’ve ever wondered whether you should boil bagels in baking soda water or if plain water will do the trick, the short answer is that baking soda makes a huge difference you can actually taste and see.
In this post, we’ll dive into why boiling bagels in baking soda water is essential, how the science works, what happens if you skip it, and the best way to do it at home.
Let’s get into the kitchen and talk bagels.
Why You Boil Bagels in Baking Soda Water
Boiling bagels in baking soda water isn’t just a random ritual—it’s a deliberate step that creates the bagel’s iconic personality.
When you boil bagels in baking soda water, the alkaline environment changes the chemistry of the dough’s outer layer.
The baking soda raises the pH level of the water, which speeds up the Maillard reaction during baking.
That reaction is what gives bagels their deep brown, shiny crust that’s slightly crisp on the outside yet chewy on the inside.
Without this alkaline bath, you’d end up with something closer to a soft bread roll than a true bagel.
1. It Sets the Crust Before Baking
Boiling bagels in baking soda water essentially pre-gelatinizes the starches on the surface of the dough.
This process sets the crust quickly, so when the bagel hits the hot oven, it won’t expand wildly like regular bread.
That’s why bagels keep their dense, chewy interior and don’t puff up into fluffy loaves.
The boiling step also prevents the bagel from rising too much, giving you that satisfying, substantial bite.
2. It Creates the Glossy Shine
The baking soda in the water interacts with the proteins on the bagel’s surface to produce that beautiful, appetizing sheen.
Boiling bagels in baking soda water makes them look bakery-fresh right out of your home oven.
If you use plain water, the bagels will bake up dull and matte, which is a giveaway that you skipped the alkaline step.
3. It Enhances the Flavor
There’s a subtle yet distinct flavor boost from boiling bagels in baking soda water.
The alkalinity gives the crust a slight tang, almost like a pretzel, which balances the malt or honey you might add to the dough.
It’s not overpowering, but it adds depth that makes bagels taste artisanal rather than homemade in a bland way.
The Difference Between Baking Soda and Lye Water for Bagels
You might have heard that professional bagel shops use food-grade lye, not baking soda, for their boiling baths.
That’s true, and lye creates an even stronger alkaline reaction, which yields a darker, shinier, and slightly more pretzel-like crust.
However, lye is caustic and requires careful handling with gloves and safety goggles, which isn’t practical for most home kitchens.
Boiling bagels in baking soda water is the accessible, safe alternative that gets you about 80% of the way there.
The key is to use enough baking soda—about 1/4 cup per large pot of water—to really bump up the alkalinity.
Some bakers even bake the baking soda first to convert it into sodium carbonate, which is stronger and closer to lye in effect.
But for a simple, reliable batch, regular baking soda straight from the box works beautifully.
What Happens If You Don’t Boil Bagels in Baking Soda Water?
If you skip the boiling step entirely, or just use plain water, your bagels will still bake but they won’t be true bagels.
Without the alkaline bath, the crust stays pale and soft, and the interior may rise too much, turning airy and bread-like.
You lose the chewy density that makes bagels satisfying to bite into.
Boiling bagels in baking soda water is what locks in that dense crumb and gives the crust its characteristic snap.
So if you’ve been skipping this step, it’s time to change your routine.
How to Boil Bagels in Baking Soda Water at Home
The process is simple, but a few details matter for the best result.
First, bring a large pot of water to a rolling boil, then stir in your baking soda.
Be careful because the water will foam up when you add the baking soda, so give it a minute to settle.
Gently drop in your shaped bagels, one or two at a time, so you don’t overcrowd the pot.
Boil each side for about 30 to 60 seconds, flipping once with a slotted spoon.
Boiling bagels in baking soda water for longer will give you a thicker, chewier crust, while a shorter boil yields a softer exterior.
After boiling, transfer the bagels to a parchment-lined baking sheet, add your toppings, and bake at a high temperature, usually 425°F to 450°F.
The result is a gorgeous, glossy, chewy bagel that rivals anything from a specialty shop.
Pro Tips for Perfect Results
Use cold water to mix your dough since slow fermentation boosts flavor and texture.
Don’t skip the boiling step even if you’re in a rush, because that’s the heart of the bagel-making process.
Boiling bagels in baking soda water works best with a wide, deep pot so the bagels float freely.
Also, pat the boiled bagels dry slightly before adding toppings to avoid soggy spots.
And if you want extra shine, brush the boiled bagels with an egg wash before baking.
So, Do You Boil Bagels in Baking Soda Water?
Yes, you boil bagels in baking soda water to achieve that authentic chewy texture, shiny crust, and slightly tangy flavor.
Boiling bagels in baking soda water is a simple yet critical technique that separates a real bagel from a bread roll.
Whether you’re a beginner or a seasoned baker, this step is non-negotiable for great results.
So next time you’re making bagels at home, don’t hesitate—boil bagels in baking soda water and taste the difference for yourself.
Happy baking, and enjoy your perfectly chewy, golden bagels fresh from your own oven.
