What Ingredients You Will Need

This recipe uses simple, wholesome ingredients to deliver bold flavor and satisfying crunch without the fuss. Most of these are pantry staples, and using sourdough discard makes it a smart way to reduce waste while making something delicious.

• Sourdough starter discard (about 100g; active or discard, room temperature) – adds tang and moisture
• All-purpose flour (1 ½ cups / 180g) – the base of the dough; you can swap with whole wheat for nuttier flavor
• Unsalted butter (4 tablespoons / 56g, cold and cubed) – gives tenderness and richness
• Grated sharp cheddar cheese (about ¾ cup / 75g) – for cheesy flavor (optional but highly recommended!)
• Salt (½ teaspoon) – enhances overall flavor
• Garlic powder (¼ teaspoon) – subtle savory note
• Onion powder (¼ teaspoon) – adds depth
• Water (2-3 tablespoons) – to bring dough together (adjust as needed)
• Optional: Smoked paprika or cayenne pepper (a pinch) for a little kick

Pro tip: I prefer using a quality sharp cheddar like Cabot for the best melt and tang, but feel free to experiment with your favorites. Also, if you don’t have sourdough discard, you can use plain yogurt or buttermilk to get a similar tangy effect.

Equipment Needed

• Mixing bowl – for combining ingredients
• Pastry cutter or two knives – to cut the cold butter into flour
• Rolling pin – to roll out the dough evenly
• Goldfish-shaped cookie cutter or small fish-shaped cutter – for that classic look (a small circle cutter can work too)
• Baking sheet lined with parchment paper or silicone mat – for even baking without sticking
• Wire rack – to cool crackers and keep them crisp
• Optional: Food processor – handy for quickly blending butter and flour, if you have one

If you don’t have a goldfish-shaped cutter, no worries! You can cut small squares or use any fun-shaped cutter you have on hand. A rolling pin with adjustable thickness rings helps keep the dough thin and consistent, but a regular rolling pin works perfectly fine. For budget-friendly baking, parchment paper works just as well as silicone mats and makes cleanup a breeze.

Preparation Method

1. Prepare the dough (10 minutes): In a large mixing bowl, combine 1 ½ cups (180g) all-purpose flour, ½ teaspoon salt, ¼ teaspoon garlic powder, and ¼ teaspoon onion powder. Toss in the grated sharp cheddar cheese and gently mix to distribute.
2. Cut in the butter: Add 4 tablespoons (56g) cold, cubed unsalted butter. Using a pastry cutter or two knives, cut the butter into the dry ingredients until the mixture resembles coarse crumbs with pea-sized bits of butter. This step is crucial for that flaky texture.
3. Add sourdough discard and water: Stir in 100g sourdough starter discard. Gradually add 2 to 3 tablespoons of water, mixing until the dough just comes together. It should be soft but not sticky. If it feels too wet, sprinkle a little more flour; too dry, add a splash more water.
4. Chill the dough (optional but recommended): Wrap the dough in plastic wrap and chill for 15 minutes. This helps the butter firm up again, making rolling easier and results in crispier crackers.
5. Roll out the dough: Lightly flour your work surface and roll the dough out to about 1/8 inch (3mm) thickness. Keep it as even as possible for uniform baking.
6. Cut into shapes: Use a goldfish-shaped cookie cutter to cut out crackers. Gather scraps, re-roll, and cut until all dough is used (try not to overwork the dough to keep it tender).
7. Place on baking sheet: Arrange crackers on a parchment-lined baking sheet, spacing them about ½ inch (1.3cm) apart.
8. Bake: Preheat your oven to 350°F (175°C). Bake crackers for 15-18 minutes or until golden and crisp around the edges. Keep an eye on them in the last few minutes to avoid burning.
9. Cool completely: Transfer crackers to a wire rack to cool. They will crisp up as they cool, so resist the urge to eat them straight from the oven (though I won’t judge if you sneak one!).

Tip: If you notice any crackers puffing up during baking, gently press them down with a spatula midway through baking for even crispness. Also, rotating your baking sheet halfway through helps bake evenly.

Cooking Tips & Techniques

Getting that perfect crispy sourdough goldfish cracker is all about attention to detail and a few well-learned tricks. Here’s what I’ve learned after countless batches:

• Keep your butter cold! This creates little pockets of fat that bake into flaky, crispy crackers.
• Don’t overwork the dough — the less you handle it, the more tender your crackers will be.
• Rolling the dough evenly to about 1/8 inch thickness ensures all crackers bake uniformly crisp without burning.
• Use parchment paper or a silicone baking mat to prevent sticking and encourage even browning.
• Watch closely during the last 5 minutes of baking; crackers can go from perfect to burnt in seconds.
• Cool crackers on a wire rack to avoid sogginess — trapped steam is the enemy of crispness!
• If your kitchen is humid, store crackers in an airtight container with a small pinch of rice to keep moisture at bay.

One time, I tried to skip chilling the dough, and the crackers spread too much and turned out dense—lesson learned! Also, multitasking by prepping your dough while the oven preheats saves precious time. Trust me, these tips will help you nail this recipe every single time.

Variations & Adaptations

Want to switch things up? This crispy sourdough goldfish crackers recipe is super versatile.

• Herb and Garlic: Add 1 teaspoon dried rosemary or thyme and extra garlic powder for a savory, aromatic twist.
• Spicy Kick: Stir in ¼ teaspoon cayenne pepper or smoked paprika for a subtle heat that pairs wonderfully with the cheddar.
• Gluten-Free: Substitute the all-purpose flour with a gluten-free blend (make sure it includes xanthan gum for binding). Expect slightly different texture but just as tasty.
• Dairy-Free: Use vegan butter and dairy-free cheese alternatives. Coconut yogurt can replace sourdough discard for tang.
• Cheese-Free: Omit the cheese and add nutritional yeast for a cheesy flavor without dairy.

Personally, I tried adding finely chopped sun-dried tomatoes and basil once — totally changed the flavor profile and was a hit at our picnic! You can bake these crackers in mini muffin tins for bite-sized cups filled with hummus or dips, too.

Serving & Storage Suggestions

These crispy sourdough goldfish crackers are best served at room temperature for maximum crunch. They make a perfect snack on their own or alongside a cheese board, fresh veggies, or your favorite dips like guacamole or spinach artichoke dip.

For storage, place cooled crackers in an airtight container at room temperature. They’ll stay crisp for up to a week. If you want to keep them longer, store in the freezer for up to 3 months—just thaw at room temperature and re-crisp in a warm oven for a few minutes.

Reheating tips: pop them in a 300°F (150°C) oven for 3-5 minutes to freshen the crunch. Flavors actually deepen the next day, so making these ahead for parties works like a charm.
