You know that moment when you can’t decide between a soft pretzel and a bagel? You want the chewy, salty crust of a pretzel but the portability and shape of a bagel. A home baker on r/Baking recently shared their answer: soft pretzel bagels. Combining the best of both worlds, these bagels get boiled in a baking soda bath before baking, giving them that signature dark, shiny pretzel crust. And the best part? You can top them with classic salted, everything seasoning, cinnamon sugar, or asiago cheese. Let’s break down the science and technique so you can make them in your own kitchen.
Baking is chemistry you can eat. Soft pretzels get their distinctive crust from being boiled in an alkaline solution — typically baking soda (sodium bicarbonate) or lye (sodium hydroxide). The alkaline bath raises the pH of the dough’s surface, which promotes the Maillard reaction during baking, producing that deep brown color and unique flavor. Bagels, on the other hand, also get boiled — but usually in plain water or water with a bit of malt syrup. The pretzel bagel combines the two: you boil in an alkaline solution, then bake at high heat. The result is a bagel-shaped roll with a pretzel’s chewy crust and a soft, airy interior.
Start with bread flour. King Arthur Flour’s bread flour or Bob’s Red Mill Artisan Bread Flour are excellent choices. Bread flour has a higher protein content (12-14%) than all-purpose flour. More protein means more gluten development, which gives bagels their essential chew. If you use all-purpose flour, your bagels will be softer and less dense — still good, but not the authentic texture.
For the dough, you’ll need:
The butter or oil enriches the dough slightly, making it tender but still chewy. Mix dry ingredients first, then add water and butter. Knead for 8-10 minutes by hand or 5-6 minutes in a stand mixer with dough hook until smooth and elastic. The dough should pass the windowpane test: stretch a small piece thin enough to see light through without tearing. Cover and let rise for 1 hour, or until doubled.
Punch down the dough and divide into 8 equal pieces (about 100g each). Shape each piece into a smooth ball, then poke a hole through the center with your finger and gently stretch to about 3 inches in diameter. Place on a parchment-lined baking sheet, cover, and let rest for 20 minutes. This short proof relaxes the gluten and helps the bagels puff slightly during boiling.
This is the critical step. You have two options: baking soda or lye.
Baking soda bath (easier, safer): Dissolve 1/4 cup (60g) baking soda in about 8 cups (2 liters) of water. Bring to a boil. The water will foam up, so use a wide pot. Boil each bagel for 30 seconds per side. The longer you boil, the thicker and chewier the crust. 30 seconds is standard for a balanced texture. Too short and the crust is pale; too long and the bagel becomes tough and dark.
Lye bath (professional, more authentic): Use food-grade lye (sodium hydroxide). Caution: lye is caustic. Wear gloves and eye protection. Do not use aluminum pots. Dissolve 1 tablespoon lye in 1 liter water (always add lye to water, not water to lye). Boil not required — just dip each bagel for 20-30 seconds. Lye gives a deeper, more authentic pretzel flavor and a shinier crust. If you’re new to pretzel making, start with baking soda.
After boiling, place bagels on a wire rack to drain briefly. They will look slightly wrinkled — that’s fine.
Immediately after boiling, brush each bagel with an egg wash (1 egg beaten with 1 tablespoon water) or just spritz with water for toppings to stick. Then add your toppings:
Bake at 425°F (218°C) for 15-18 minutes, rotating halfway through. The bagels should be deep golden brown and sound hollow when tapped on the bottom. Let cool on a wire rack for at least 10 minutes before serving. The interior continues to set as it cools.
For an even more authentic pretzel bagel, try a cold fermentation. After shaping, refrigerate the formed bagels overnight (covered). This develops flavor and improves crust color. Boil and bake directly from the fridge — no additional proofing needed.
Soft pretzel bagels are a perfect canvas for creativity. The r/Baking community loved these four flavors, but don’t stop there: try jalapeño cheddar, garlic parmesan, or even chocolate chip for a sweet twist. Remember, understanding the science — why we boil in alkali, why bread flour matters — turns a good recipe into a great one. So preheat your oven, bring that water to a boil, and get ready to enjoy something that’s both pretzel and bagel. That’s kitchen fun.

Have you ever bitten into a chocolate chip cookie that stopped you in your tracks? One with a depth of flavor that was nutty, almost like toffee, but you couldn’t quite identify the source? I’m willing to bet the secret was brown butter.

You’ve done everything right. You baked perfectly level cake layers, whipped up a dreamy filling, and stacked it all with precision. Now comes the final coat of frosting. You spend ages with your offset spatula and bench scraper, chasing that elusive, flawless finish you see in bakeries and on social media. But when you step back, the edges are… soft. A little rounded. Maybe there’s a slight bulge around the middle. In a warm room, you can almost see it start to sag.
