Crunchy Everything Bagel Protein Crackers

These paper-thin crackers deliver satisfying crunch with 12g protein per serving. The sourdough discard creates a light, airy texture while the everything bagel seasoning gives that addictive salty-oniony flavor we all love.

What You’ll Need

• 1 cup sourdough discard (100% hydration)
• 1/2 cup almond flour (for protein and crispness)
• 1/4 cup nutritional yeast (cheesy flavor boost)
• 3 tbsp Greek yogurt (plain, full-fat recommended)
• 2 tbsp olive oil

Crafting Your Crispy Canvases

• Preheat oven to 325°F with racks in upper and lower thirds

• Place first portion between two silicone baking mats or parchment sheets
• Roll to 1/16-inch thickness – should be nearly translucent
• Remove top mat, sprinkle with half the everything seasoning
• Gently roll over seasoning to press into dough
• Cut with pizza wheel into 1-inch squares (don’t separate)
• Repeat with second dough portion
• Bake 25-30 minutes until golden, rotating sheets halfway
• Cool completely on racks before breaking into crackers

Pro Tips for Perfect Crackers

• Thickness matters: Roll thinner than you think – crackers puff slightly during baking
• Baking surface: Use light-colored baking sheets for even browning
• Storage secret: Keep in airtight container with silica packet to maintain crunch

Keeping Your Creations Fresh

Storage Solutions

Crackers & Chips: Store in airtight container at room temperature 1 week, or freeze 3 months. Refresh in 300°F oven 5 minutes if they lose crispness.

Muffins: Keep in fridge 5 days or freeze 2 months. Reheat frozen muffins straight in toaster oven 8-10 minutes at 325°F.

Reviving Leftovers

• Muffin makeover: Slice horizontally, toast until crispy, top with avocado or hummus
• Cracker crumbs: Pulverize stale crackers to use as breading for chicken or fish
• Chip upgrade: Crush over soups or salads for crunchy protein topping

Common Pitfalls & How to Avoid Them

• Gummy texture: Ensure oven temperature is accurate with thermometer
• Crackers sticking: Always use silicone mats, not parchment
• Bland flavor: Let dough rest 1 hour for sour flavor development
• Uneven baking: Rotate pans front-to-back and top-to-bottom halfway
• Burnt edges: Use light-colored aluminum pans instead of dark metal

Your Sourdough Snacking Questions Answered

Can I use frozen sourdough discard?

Absolutely! Thaw overnight in fridge. If liquid separates, stir well before using. Frozen discard works particularly well in the muffin recipe.

How do I make these gluten-free?

While sourdough contains gluten, these recipes use minimal flour. For gluten-free version, use gluten-free starter with certified GF oat flour instead of almond.

Can I substitute almond flour?

Sunflower seed flour works 1:1 for nut-free option. For lower-fat option, use whole wheat pastry flour but expect denser texture.

Why do my crackers puff up like pita bread?

This happens if dough is too thick or oven too hot. Roll thinner than you think necessary and verify oven temp with thermometer.

Can I increase protein further?

Add 1-2 tbsp unflavored whey or plant-based protein powder to any recipe. Increase liquid slightly if dough becomes dry.

How do I know when my chips are done?

They should look dry with slightly browned edges. They crisp further as they cool. Undercook slightly if you prefer more flexible chips.
