The moment you slice into a fresh Jalapeño Cheddar Sourdough Bagel, you're greeted with an enticing aroma that combines the complex tang of sourdough with the savory notes of melted cheddar and the bright, spicy scent of jalapeños. Each bite delivers a perfect textural contrast—the distinctive chewy crust gives way to a dense yet tender interior studded with pockets of molten cheese and zesty pepper pieces. This isn't just a bagel; it's a harmonious fusion of traditional sourdough bagel-making techniques with bold, southwestern-inspired flavors that transform breakfast into something truly extraordinary.
Last weekend, I made these for a family brunch, and my brother-in-law, who typically grabs store-bought bagels on his way to work, declared them 'worth waking up early for.' Watching everyone's eyes light up as they pulled apart the cheese-crusted tops was just as satisfying as the bagels themselves.
Essential Ingredients and Selection Tips
- Sourdough Starter: Use an active, bubbly starter at its peak for best results. If using discard, supplement with ¼ teaspoon active dry yeast per cup of flour.
- Bread Flour: The higher protein content (12-14%) is crucial for developing the chewy texture bagels are known for.
- Cheddar Cheese: Opt for a sharp or extra-sharp cheddar for pronounced flavor that stands up to the sourdough tang.
- Jalapeños: Fresh jalapeños provide bright heat and vibrant color, while pickled offer consistent spice level and longer shelf life.

Detailed Cooking Instructions
- Prepare Your Starter:
- Use 150g active sourdough starter at peak activity, or supplement discard with 1 tsp yeast in 2 tbsp warm water.
- Create the Dough Base:
- Mix 300g water, 500g bread flour, 10g salt, and 15g sugar in a stand mixer. Knead for 5-7 minutes until smooth.
- Develop Structure and Flavor:
- Hand knead for 2-3 minutes, then form into a ball and let rise in a warm spot for 4-6 hours.
- Prepare Add-ins:
- Grate 150g sharp cheddar and slice 3-4 jalapeños. Set aside 1/3 of the cheese and jalapeño rings for topping.
- First Fold and Rest:
- Gently deflate dough, stretch into a rectangle, and sprinkle with cheese and jalapeños. Fold, then rest for 30 minutes.
- Divide and Pre-shape:
- Divide into 8 portions (~115-120g each), form into balls, and let rest for 15 minutes.
- Shape the Bagels:
- Press thumb through center of each ball to form a 1½-inch hole. Alternatively, roll into ropes and connect ends.
- Cold Fermentation:
- Refrigerate bagels for 12-18 hours for deep flavor development.
- Prepare for Baking:
- Remove from fridge and let stand for 45-60 minutes. Preheat oven to 450°F.
- Boil the Bagels:
- Boil in sweetened water (1 tbsp honey) for 45 seconds per side.
- Add Toppings and Bake:
- Sprinkle bagels with reserved cheese and jalapeño slices. Bake for 20-25 minutes until golden brown.
- Cool and Enjoy:
- Let cool for 20 minutes before slicing.
My first attempt at these bagels taught me that patience with the fermentation process yields superior results. I rushed the cold proof once and ended up with bagels that were more like rolls with holes.
Temperature management throughout the process significantly impacts the final product. The dough should visibly increase in volume and feel puffy when gently pressed.
Cheese and jalapeño distribution requires thoughtful technique—folding creates layers of flavor without compromising the dough.
These Jalapeño Cheddar Sourdough Bagels bring together multiple culinary traditions—Polish bagels, Southwestern flavors, and ancient sourdough fermentation.
The contrast between the crunchy cheese crust, chewy exterior, and bursts of spicy jalapeño creates a multi-dimensional eating experience.
These bagels represent the perfect balance between tradition and innovation, blending heritage baking techniques with bold modern flavors.

Frequently Asked Questions
- → Can I use sourdough discard for these bagels?
- Yes, you can use either sourdough discard or fed, active starter for this recipe. Both will work well, though active starter may give you a slightly better rise.
- → How spicy are these Jalapeño Cheddar Sourdough Bagels?
- The spice level depends on how many jalapeño slices you use. The recipe suggests about 4-5 slices per bagel, but you can adjust this to your heat preference. Using pickled jalapeños (as recommended) typically provides moderate heat with great flavor.
- → Can I make these bagels with regular flour instead of bread flour?
- While bread flour is ideal for bagels because of its higher protein content that creates chewiness, you can use all-purpose flour in a pinch. The bagels won't be quite as chewy but will still be delicious.
- → How should I store these Jalapeño Cheddar Sourdough Bagels?
- Store cooled bagels in an airtight container at room temperature for 2-3 days. For longer storage, slice and freeze them in a freezer bag for up to 3 months. Thaw and toast to enjoy.
- → What can I serve with these bagels?
- These bagels are delicious with plain cream cheese, which balances the heat nicely. They also work well with avocado, eggs, or as sandwich bread with turkey or ham. For a spicier option, try jalapeño cream cheese.
