What is a Bagel? Origins & How It’s Made

The History of Bagel – A Jewish Culinary Staple

Bagels are a staple in American breakfast culture, and for good reason. These dense, chewy rings of dough have been around for centuries, originally brought over by Jewish immigrants from Poland. Today, bagels come in every flavor imaginable—everything bagels, cinnamon raisin, blueberry, asiago cheese—but at their core, they all follow the same boiling and baking process.

How Bagel Are Made – The Boil and Bake Process

The key to a bagel’s texture is its unique cooking method:

1. Dough Preparation – Made with flour, water, yeast, salt, and sometimes sugar or malt syrup.
2. Shaping & Proofing – The dough is formed into rings and left to rise.
3. Boiling – This step is what makes a bagel a bagel! The rings are boiled briefly, giving them that iconic chewy crust.
4. Baking – They’re finished off in a hot oven to get a crispy, golden-brown exterior.

This boiling step is what sets bagels apart from other breads. It creates a dense, slightly sweet bite, which is why they hold up so well to cream cheese, butter, or even as a base for sandwiches (like a good old chicken burrito bagel sandwich—yep, that’s a thing!).

What is Sourdough Bread? Fermentation & Baking Process

The Ancient History of Sourdough – The Oldest Bread in the World

Sourdough is one of the oldest types of bread in the world. Unlike bagels, which rely on commercial yeast, sourdough gets its rise from a natural fermentation process using a starter—a mix of flour and water that captures wild yeast and good bacteria from the air.

How Sourdough is Made – The Slow Fermentation Method

Making sourdough takes more time and patience, but it’s totally worth it:

1. Creating a Starter – This is the base of all sourdough bread. It ferments over days, creating natural yeast.
2. Mixing the Dough – Flour, water, and salt are combined with the starter. No commercial yeast needed!
3. Bulk Fermentation – The dough is left to rise slowly, sometimes overnight.
4. Shaping & Proofing – It’s shaped into loaves and left to rise again.
5. Baking – A super hot oven (sometimes with steam) gives sourdough that crispy crust and airy texture.

This slow fermentation process develops a deep, tangy flavor while also making sourdough easier to digest. Some people even say that sourdough is better for gluten-sensitive folks because the natural bacteria break down some of the gluten during fermentation.

Bagel vs Sourdough – Key Differences in Ingredients & Preparation

Bagels and sourdough bread might both be made from flour and water, but their preparation methods couldn’t be more different. The biggest contrast comes down to fermentation and cooking techniques.

1. Bagel Preparation – The Boil and Bake Method

Bagels follow a fast, structured process. Their unique texture comes from a combination of yeast fermentation, boiling, and high-heat baking.

Step-by-Step Bagel Making Process

• Mixing the Dough – A simple mix of flour, water, yeast, and salt forms a stiff dough. Some recipes also add malt syrup for a slight sweetness.
• Shaping – Bagels are shaped into rings, either by rolling out ropes and connecting the ends or by punching a hole through a dough ball.
• Proofing – They rise for a few hours or overnight in the fridge, which helps develop flavor.
• Boiling – This is what gives bagels their signature chewiness. Boiling in water (sometimes with added honey or malt syrup) locks in moisture and creates a dense crust.
• Baking – They are baked at a high temperature, often on a stone or baking sheet, which results in a golden, crispy outer layer.

Boiling bagels before baking is what makes them thicker, denser, and chewier compared to most bread. Unlike sourdough, bagels rely entirely on commercial yeast for their rise, making them faster to produce.

If you love the idea of homemade bread but want something softer and slightly richer, try a braided chocolate chip brioche—it’s a completely different style but equally satisfying.

2. Sourdough Preparation – The Slow Fermentation Process

Sourdough takes a completely different approach. Instead of commercial yeast, it uses a wild yeast starter that ferments over days to create natural leavening.

Step-by-Step Sourdough Making Process

• Creating a Starter – A mix of flour and water ferments naturally over a week, collecting wild yeast and bacteria.
• Mixing the Dough – The starter is combined with flour, water, and salt. There’s no commercial yeast involved.
• Bulk Fermentation – The dough rises slowly over 12 to 24 hours, which develops complex flavors.
• Shaping – It’s gently shaped into loaves to avoid deflating the air pockets.
• Final Proofing – The dough rests again, often in the fridge overnight, to enhance structure and taste.
• Baking – It’s baked at high heat, often with steam, creating a crisp crust and airy, chewy interior.

Sourdough’s long fermentation process naturally breaks down some gluten and starches, making it easier to digest than traditional bagels. Some people even prefer sourdough bagels, which combine the fermentation benefits with the classic bagel shape—if that interests you, check out this sourdough vs. regular bagels comparison for more details.

3. Key Differences in Cooking Methods

Bagels are best for those who love a hearty, chewy texture, while sourdough is ideal for fans of complex flavors and crisp crusts.

Taste & Texture – How Do They Compare?

The difference in preparation directly affects how each bread tastes and feels when you bite into it.

1. Bagel Taste and Texture

Bagels are dense, chewy, and slightly sweet, depending on the type. The boiling step locks in moisture, creating a thicker crust than regular bread.

• Chewiness – The boiling process makes bagels much denser than sourdough.
• Mild Sweetness – Some bagels, especially those with malt syrup, have a subtle sweetness.
• Soft Inside, Firm Outside – The inside is compact but soft, while the crust has a firm bite.

Bagels are best enjoyed fresh, but they can get tough after a day. Storing them properly is key—check out these storing sourdough bagel tips if you want to keep them fresh longer.

2. Sourdough Taste and Texture

Sourdough is lighter, crispier, and tangier than a bagel. Its flavor depends on how long it ferments—the longer, the stronger the tang.

• Crispy Crust – Baked at high heat, sourdough develops a crunchy outer layer.
• Soft, Airy Interior – Unlike dense bagels, sourdough has an open crumb structure.
• Tangy Flavor – Thanks to fermentation, sourdough has a natural sourness that bagels lack.

The crisp crust and deep flavor of sourdough make it a perfect pairing for savory dishes. If you’re looking for a new way to enjoy it, try pepperoni pizza bombs—they bring together chewy dough and bold flavors in an easy-to-make snack.

Nutritional Comparison – Is Sourdough Healthier Than Bagel?

Now that we’ve covered how bagels and sourdough are made, let’s get into the real question—which one is healthier?

While both are delicious, they have major differences in calories, carbs, protein, fiber, and how they affect digestion. Whether you’re trying to lose weight, eat cleaner, or manage blood sugar, knowing what’s in each will help you choose the better option for your diet.

1. Calories & Carbohydrates – Which One is Lighter?

Bagels are known for being calorie-dense, while sourdough tends to be lighter per slice.

• Bagels pack more calories and carbs per serving. One large bagel can have 300-400 calories and over 60g of carbs—similar to eating 4 slices of white bread.
• Sourdough has fewer carbs and calories per slice. Thanks to its fermentation process, it also tends to be more filling despite having fewer calories.

If you’re trying to cut carbs or lose weight, sourdough is usually the better option.

2. Fiber & Digestion – Which One is Easier on the Stomach?

Fiber plays a big role in how full you feel and how your body processes carbs.

• Sourdough has more fiber than most bagels, especially whole wheat varieties.
• Fermentation breaks down some starches, making sourdough easier to digest.
• Bagels are more processed and have lower fiber unless made with whole grains.

This means that sourdough keeps you full longer while causing less of a blood sugar spike compared to bagels.

For a fiber-packed meal idea, pair sourdough toast with a ground chicken Mexican corn topping—it’s a flavorful way to keep things balanced.

3. Blood Sugar Impact – Which One is Better for Diabetics?

The glycemic index (GI) measures how fast a food raises blood sugar. Lower numbers mean a slower rise (which is better for steady energy levels).

• Bagels have a high GI, meaning they cause quick blood sugar spikes.
• Sourdough has a lower GI due to its fermentation process, making it better for blood sugar control.

For diabetics or those watching blood sugar, sourdough is the safer bet.

4. Protein & Satiety – Which One Keeps You Full?

Both bagels and sourdough have moderate protein levels, but bagels tend to have slightly more due to their denser structure.

• Bagels (especially whole wheat) can have 10g of protein per serving.
• Sourdough typically has around 6-8g of protein per slice.

If you’re looking for a high-protein breakfast, consider topping your bagel or sourdough toast with jazzed-up eggs—a simple way to add flavor and nutrients.

5. Gut Health & Gluten – Is Sourdough Better?

One of sourdough’s biggest advantages is its gut-friendly fermentation process.

• Natural fermentation breaks down gluten and phytic acid, making it easier on digestion.
• Sourdough contains beneficial bacteria, which can support a healthy gut microbiome.
• Bagels, especially white ones, are more processed and can cause bloating for some people.

If you have mild gluten sensitivity, you might tolerate sourdough better than a standard bagel. However, neither is suitable for gluten-free diets.

Gluten Content – Is Sourdough Really Better for Gluten Sensitivity?

Gluten is a big deal when choosing between bagels and sourdough. While neither is gluten-free, sourdough has a reputation for being easier to digest—but is that actually true? Let’s break it down.

1. How Much Gluten is in Bagel vs Sourdough?

Both bagels and sourdough use wheat flour, which naturally contains gluten. However, their preparation affects how much gluten stays in the final product.

Why Do Bagel Have More Gluten?

Bagels are made with high-protein flour (often called “bread flour”), which has more gluten than all-purpose or whole wheat flour. This is what gives them that signature chewy, dense texture.

Why Does Sourdough Have Less Gluten?

Sourdough fermentation naturally breaks down some gluten proteins over time. The longer it ferments, the more gluten gets broken down. This is why some people with mild gluten sensitivity can tolerate sourdough better than bagels.

However, sourdough is NOT gluten-free. If you have celiac disease, neither bagels nor sourdough are safe options.

If you’re looking for a lower-gluten alternative, try sourdough bagels—they combine the benefits of fermentation with the classic bagel shape.

2. Is Sourdough Easier to Digest Than Bagel?

How Fermentation Helps Digestion

Sourdough’s long fermentation process does two important things:

• Breaks Down Gluten – The wild yeast and bacteria partially digest gluten, making it less irritating to some people.
• Reduces Anti-Nutrients – Phytic acid, a compound in grains that blocks nutrient absorption, is reduced during fermentation.

This means sourdough is generally easier on the stomach compared to bagels.

If you struggle with bloating after eating bagels, switching to a long-fermented sourdough might help. For a different gut-friendly meal, try cottage cheese air fryer baked potato skins—they’re easy to digest and packed with protein.

3. Can People with Gluten Sensitivity Eat Sourdough?

It depends on how sensitive you are to gluten.

• Mild Gluten Sensitivity – Some people find sourdough easier to digest because the gluten is partially broken down.
• Severe Gluten Sensitivity or Celiac Disease – Even though fermentation reduces gluten, sourdough still contains enough to trigger symptoms.

If you have celiac disease or severe gluten intolerance, you’ll need a completely gluten-free bread instead of bagels or sourdough.

4. Which One is the Better Choice for Gluten Sensitivity?

If you’re not sensitive to gluten, both are fine choices. But if you experience mild bloating or discomfort, sourdough is usually the better option.
