Best Baking Soda Substitute in Bagels

5 tested options with exact ratios, science-backed explanations, and tips for success.

Quick Answer

The best substitute for Baking Soda in Bagels is Baking Powder because it provides the necessary leavening through a balanced acid-base reaction, helping achieve the characteristic chewy texture and slight rise without altering the flavor significantly.

Cream of Tartar + Baking Powder 1/2 teaspoon cream of tartar + 1/2 teaspoon baking powder per 1 teaspoon baking soda
Baker’s Ammonia (Ammonium Carbonate) Use 1/2 teaspoon baker’s ammonia per 1 teaspoon baking soda

Detailed Guide: Each Baking Soda Substitute in Bagels

Baking Powder (Best Option)

3 teaspoons baking powder per 1 teaspoon baking soda
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: Baking powder will add leavening but may produce a slightly softer crumb and less chewiness compared to baking soda.

Baking powder contains both an acid and a base, allowing it to react and produce carbon dioxide gas when moistened and heated, which helps the bagels rise. This mimics the leavening effect of baking soda but with a milder reaction.

To use baking powder successfully in bagels, increase the amount to about three times the baking soda called for, as baking powder is less concentrated. Watch for a slightly different rise and texture, as the reaction is slower and less intense.

The final bagel will be less dense and chewy than with baking soda, with a lighter crumb and slightly different crust texture, but still acceptable for most recipes.

Potassium Bicarbonate

1:1 substitution (1 teaspoon potassium bicarbonate per 1 teaspoon baking soda)
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: May impart a slight bitter taste; best used with added acid to balance flavor.

Potassium bicarbonate is chemically similar to baking soda and can provide the same leavening effect by releasing carbon dioxide when reacting with acids in the dough. It is often used as a low-sodium alternative.

When substituting, it is important to add a small amount of acid (like cream of tartar or lemon juice) to ensure proper leavening and to counteract any bitterness. Monitor the dough for rise and adjust acid levels accordingly.

The bagel texture will be close to the original, but a slight off-flavor may be noticeable if acid is not balanced properly.

Club Soda

Replace the liquid in the recipe with an equal volume of club soda

Quick tip: Provides mild leavening and moisture but results in less chewiness and denser texture.

Club soda contains dissolved carbon dioxide which can provide some leavening during mixing and baking, introducing bubbles that help lighten the dough slightly.

Use club soda to replace the water or other liquids in the recipe to introduce carbonation. However, this is a less reliable substitute because the carbonation dissipates quickly and does not provide the same chemical leavening effect.

Bagels made with club soda tend to be denser and less chewy, lacking the characteristic texture baking soda imparts, but it can be a useful option in a pinch.

Cream of Tartar + Baking Powder

1/2 teaspoon cream of tartar + 1/2 teaspoon baking powder per 1 teaspoon baking soda
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: Adds acidity and leavening but may alter flavor slightly and increase crumb softness.

Cream of tartar is an acid that can react with baking powder to enhance leavening when baking soda is unavailable. This combination attempts to replicate the acid-base reaction that baking soda provides.

Mix cream of tartar with baking powder to balance the leavening and acidity. This requires careful measurement to avoid over-acidifying the dough, which can affect taste and texture.

The resulting bagels may be softer and less chewy, with a slightly tangier flavor, differing from traditional baking soda-leavened bagels.

Baker’s Ammonia (Ammonium Carbonate)

Use 1/2 teaspoon baker’s ammonia per 1 teaspoon baking soda
Vegan Gluten-Free Dairy-Free Fat-Free Nut-Free
Quick tip: Produces a crisp crust but can cause a strong ammonia odor if not baked thoroughly.

Baker’s ammonia decomposes into ammonia and carbon dioxide gas when heated, providing leavening and a crisp crust. Historically used in some traditional baked goods, it can mimic some effects of baking soda.

Use sparingly and ensure thorough baking to avoid residual ammonia smell. It works best in thin or small baked goods but can be tricky in dense dough like bagels.

Bagels may have a crisper crust but risk off-flavors and uneven texture if not handled carefully, making it a less ideal substitute.

❌ What NOT to Use as a Baking Soda Substitute in Bagels

Yeast

Yeast is not a suitable substitute for baking soda in bagels when the recipe specifically calls for baking soda for boiling or quick leavening, as yeast requires fermentation time and changes the texture and flavor profile significantly.

Potassium Bicarbonate

While chemically similar to baking soda, potassium bicarbonate lacks the same leavening strength and can impart a bitter aftertaste, which negatively affects the traditional bagel flavor and texture.

Self-Rising Flour

Self-rising flour contains baking powder and salt, but substituting baking soda with it in bagels disrupts the precise control over leavening and salt content, resulting in inconsistent texture and flavor.
