Sourdough Bagels vs. Sourdough Pretzels: What's the Difference?

Bagels and pretzels are both boiled-then-baked breads, both can be made with sourdough, and both are confused by beginners. Here's how they actually differ — in dough, technique, and result.

The high-level difference

Bagels — chewy, dense bread, originally Jewish/Polish, with a hole in the middle.

Pretzels — soft, browned, originally German, in twisted shapes (or rolls, sticks, etc.).

The boil makes them both unusual. But what's IN the boil and HOW determines the final character.

Dough differences

Bagel dough

• 50–55% hydration (very stiff)
• Higher protein flour (13%+)
• Sometimes barley malt syrup in the dough
• Long bulk fermentation (often 12–24 hours cold)
• Result: dense, chewy interior

Pretzel dough

• 50–55% hydration (also stiff)
• Slight enrichment (sugar, butter, sometimes egg)
• No malt syrup needed
• Shorter bulk fermentation (4–8 hours)
• Result: softer, more bread-like interior

Both are stiff doughs. But the pretzel is slightly enriched, slightly softer.

Boil differences

Bagel boil

• Plain water + a small amount of barley malt syrup
• Sometimes baking soda (small amount)
• Boil 30 seconds per side
• pH is slightly alkaline but mostly neutral

Pretzel boil/dip

• Water + a substantial amount of baking soda (or food-grade lye)
• Highly alkaline solution
• Dip 15–30 seconds (each side, or just a single dip)

The pretzel dip is much more alkaline than the bagel boil. This is what creates the characteristic pretzel:

• Mahogany color
• Distinct "twangy" flavor
• Soapy crust feel
• Maillard browning enhanced

Bake differences

Bagels

• 450°F for 18–22 minutes
• Bake to deep golden
• Dense, chewy interior
• Crusty exterior

Pretzels

• 450°F for 12–14 minutes (smaller pieces)
• Bake to deep mahogany
• Soft interior
• Glossy, slightly thick crust

Pretzels bake faster because they're smaller and the alkaline dip accelerates browning.

Flavor profile

Bagels

• Wheaty, slightly malty
• Mildly sour from sourdough
• Dense, satisfying chew
• Best with cream cheese, lox, etc.

Pretzels

• Distinctively "twangy" (alkaline) flavor
• Slightly sweet from sugar in dough
• Salty from coarse salt topping
• Best with mustard, beer cheese, butter

Shaping

Bagels

Two options:

• Roll into a rope, wrap around your hand, pinch ends together
• Poke a hole in a ball with your thumb, stretch wider

Pretzels

Twist a long rope into the classic pretzel shape:

• Form a U with the rope
• Twist the ends together once or twice
• Fold the twisted ends down onto the bottom of the U

Each requires practice. Bagels are slightly easier for beginners.

Topping differences

Bagels

• Sesame seeds
• Poppy seeds
• Everything seasoning
• Sea salt
• Cinnamon raisin (in dough)
• Various

Pretzels

• Coarse pretzel salt (always)
• Sometimes additional flavors (cinnamon sugar for sweet versions)

Pretzels are simpler in topping.

Storage

Bagels

Best within 24 hours. Then:

• Slice in half horizontally
• Freeze in zip-top bag
• Toast directly from frozen

Stale bagels make excellent French toast.

Pretzels

Best within 4 hours of baking. Then:

• Soften noticeably
• Freeze whole or as bites
• Reheat at 350°F for 5 minutes

Pretzels don't keep as well as bagels.

Calories and nutrition (rough)

A standard bagel: ~280 calories, lots of carbs.

A standard soft pretzel: ~340 calories, slightly higher fat.

Both are bread. Eat in moderation.

Common confusion points

"Pretzel bagels"

Some bakeries make "pretzel bagels" — bagels dipped in alkaline solution. These have:

• Bagel shape
• Pretzel exterior color and flavor
• Bagel interior chew

It's a fusion. Not common but excellent.

Boiling vs. dipping

• Bagels are boiled (immersed and held in boiling water for 30 seconds)
• Pretzels are sometimes dipped (briefly in cold or hot alkaline solution) or boiled in alkaline solution

Both methods accomplish similar things — pre-cooking the surface.

Which is harder to make

For a beginner sourdough baker:

• Bagels: medium difficulty (shaping is fiddly, boil is easy)
• Pretzels: harder (alkaline dip requires care, shaping is more complex)

If choosing between them for a first time, bagels are slightly easier.

A crossover technique

If you have great bagel dough:

• Form into pretzel shapes instead of bagel shapes
• Dip in alkaline solution
• Bake hot

You get pretzel-bagels. Excellent.

Cultural notes

Bagels

• Originated in Jewish communities of Eastern Europe
• Brought to America by immigrants
• New York and Montreal styles diverged
• Now globally beloved

Pretzels

• Originated in German Christian monasteries
• Soft pretzels remain regional in Germany and Pennsylvania
• Hard pretzels became a global snack

Both have deep histories. Each represents a distinct culinary tradition.

When to make each

Make bagels when:

• You want bread with chewy texture and complex flavor
• You'll be eating with savory toppings (cream cheese, lox, deli meats)
• You want bread that lasts (with freezing)
• You have time for a 24-hour cold ferment

Make pretzels when:

• You want a snack or appetizer
• You're hosting a casual gathering (especially with beer)
• You want immediate gratification (bites bake in 12 minutes)
• You like the distinctive pretzel flavor

A recipe comparison

I've covered both in depth:

• For bagels: see [Sourdough Bagels at Home](/blog/sourdough-bagels-detailed)
• For pretzels: see [Sourdough Pretzels](/blog/sourdough-pretzels)
• For pretzel bites: see [Soft Pretzel Bites with Sourdough](/blog/sourdough-soft-pretzel-bites)

Each has its own technique. Mastering both expands your sourdough range significantly.

Why both belong in a sourdough kitchen

A sourdough baker who can make bagels and pretzels has expanded beyond country loaves. Both:

• Showcase sourdough's versatility
• Use specific techniques (boil + bake)
• Produce instantly recognizable bread
• Impress people who try them

Adding both to your repertoire makes you a more complete baker.

A final note on the boil

The boil is what makes both these breads special. Without it, they'd be just bread.

Embrace the boil. It's not optional. It's the defining technique of these two iconic breads.
