Do you have to boil bagels in baking soda? You don’t have to boil bagels in baking soda, but doing so is the secret to that shiny, chewy, and deeply golden crust you expect from a true bagel.
While there are alternative methods, the baking soda bath is a classic move that home bakers love because it’s simple, affordable, and delivers such professional-looking results.
If you’ve ever wondered whether you can skip this step or swap it for something else, you’re in the right place.
In this post, we’ll break down why you’d boil bagels in baking soda, what happens if you don’t, and how to nail that signature texture every single time.
Let’s get into the doughy details.
Why You Should Boil Bagels in Baking Soda
The reason you boil bagels in baking soda comes down to chemistry, and it’s a game-changer for your homemade rounds.
Boiling bagels in baking soda alters the pH level on the surface of the dough, which directly affects how the crust browns in the oven.
When you boil bagels in baking soda, the alkaline solution reacts with the starches on the outside, creating a thin gelatinized layer.
That layer is what gives bagels their signature blistered, crackly exterior once they hit high heat.
So, if you’re aiming for that authentic New York-style chew, boiling bagels in baking soda is the way to go.
1. It Creates the Iconic Shiny Crust
Boiling bagels in baking soda is the primary reason your bagels come out with that glossy, lacquered look.
The alkaline bath encourages browning reactions on the surface, which produce a deep mahogany color you just can’t get from baking alone.
Without this step, your bagels will still taste good, but they’ll look pale and more like dense bread rolls.
If you want that beautiful, appetizing shine, you really should boil bagels in baking soda.
2. It Locks in the Chewy Texture
Another reason you boil bagels in baking soda is to set the crust before the inside finishes baking.
This quick boil firms up the outer layer, so the bagel can’t expand too much in the oven.
That means you get a denser, chewier crumb with a satisfying bite, not a fluffy, airy bread texture.
So, when you boil bagels in baking soda, you’re essentially controlling the final structure of your bagel.
3. It Adds a Subtle Flavor Kick
Though subtle, boiling bagels in baking soda introduces a faint, pretzel-like tang to the crust.
That slight alkaline flavor is part of what makes bagels taste so distinct from other breads.
It’s not overpowering, but it adds a layer of complexity that makes your homemade bagels taste authentic.
For that reason alone, many bakers insist you boil bagels in baking soda every single time.
What Happens If You Don’t Boil Bagels in Baking Soda?
You don’t have to boil bagels in baking soda, but skipping it absolutely changes the final product.
Let’s break down what you can expect if you skip the bath and go straight to the oven.
1. You’ll Get a Softer, Bread-Like Crust
Without boiling bagels in baking soda, the crust won’t set the same way.
Your bagels will bake up with a softer, thinner shell that feels more like a dinner roll.
They’ll puff up more in the oven, giving you a lighter, less dense interior.
That’s not necessarily bad if you prefer a softer bagel, but it’s not traditional.
2. The Color Won’t Be as Deep or Golden
If you don’t boil bagels in baking soda, you’ll notice the crust stays pale and matte.
The alkaline reaction is what promotes that beautiful browning, so without it, you’ll have to rely on longer baking times or egg washes.
Even then, you won’t replicate that distinctive blistered look that boiling bagels in baking soda gives you.
3. The Chew Factor Drops Significantly
One of the biggest differences when you don’t boil bagels in baking soda is the lack of chew.
The boiling process gelatinizes the starches on the outside, which creates that dense, snappy bite.
Skipping it means your bagel will be airier and more cake-like, which some folks actually love.
But if you’re chasing that traditional bagel experience, you should boil bagels in baking soda.
Can You Use Baking Soda Alternatives When Boiling Bagels?
You don’t always have to boil bagels in baking soda because there are other alkaline helpers you can try.
Here’s what you can use instead and how they compare to the classic baking soda method.
1. Lye Solution for a More Authentic Crust
Professional bagel shops often use food-grade lye instead of baking soda.
Lye is much stronger, so it creates an even darker, shinier, and more crackly crust.
However, lye is caustic and requires careful handling, so it’s not ideal for casual home bakers.
If you’re comfortable with safety precautions, boiling bagels in a lye solution takes things up a notch.
2. Baked Baking Soda for a Stronger Alkaline Boost
If you want to get closer to lye results but still want to boil bagels in baking soda, try baking the baking soda first.
Spread baking soda on a baking sheet and heat it at 250°F for about an hour.
This converts some of it into washing soda, making the solution more alkaline and closer to lye’s effect.
It’s a clever hack if you want a darker crust without handling dangerous chemicals.
3. Honey or Sugar in the Water for a Sweeter Crust
Some recipes skip the alkaline route and add honey or malt syrup to the boiling water instead.
This gives bagels a subtle sweetness and a lovely golden color, but it won’t produce that same glossy, chewy crust.
So, while you don’t have to boil bagels in baking soda, adding sweeteners is a tasty alternative if you’re okay with a softer texture.
How to Boil Bagels in Baking Soda the Right Way
Now that you know why you should boil bagels in baking soda, let’s talk about doing it correctly.
Follow these simple steps for perfect results every time.
1. Use a Generous Amount of Baking Soda
For a standard pot of water (about 8 cups), add 2 to 3 tablespoons of baking soda.
More baking soda means a more alkaline water, which gives you a darker, shinier crust.
Just don’t go overboard, as too much can leave a metallic aftertaste.
2. Bring the Water to a Gentle Boil
You don’t need a rolling boil when you boil bagels in baking soda.
A gentle simmer is perfect because it allows the bagels to cook evenly without wrinkling.
Drop your bagels in one or two at a time, making sure they have room to float.
3. Boil Each Side for 30 Seconds to a Minute
Boil bagels in baking soda for about 30 seconds per side for a thinner crust, or up to 60 seconds for a thicker, chewier shell.
Use a slotted spoon to flip them carefully and remove them when they look slightly puffed but still firm.
Then, transfer them to a wire rack to drain before popping them into a hot oven.
So, Do You Have To Boil Bagels in Baking Soda?
You don’t have to boil bagels in baking soda, but you absolutely should if you want that classic bagel experience.
Boiling bagels in baking soda gives you the shiny, blistered crust, the dense chewy interior, and that subtle alkaline flavor that sets bagels apart from other breads.
If you prefer a softer, roll-like bagel or you’re just in a hurry, you can skip the bath and bake them directly.
But for the real deal, take the extra few minutes to boil bagels in baking soda.
Your taste buds will thank you, and you’ll feel like a pro every time you pull a golden batch out of the oven.
Now grab your mixing bowl and get boiling.
