In a large mixing bowl, combine:

• Flour
• Onion powder
• Sugar
• Salt
• Baking powder
• Garlic powder (if using)

Mix until evenly combined.

Step 2: Add the Butter

Add the cold butter cubes.

Using a pastry cutter, fork, or your fingertips, rub the butter into the flour until the mixture resembles coarse crumbs.

Small butter pieces will help create flaky crackers.

Step 3: Add the Onion

Stir in the finely grated onion.

Mix until evenly distributed.

If the dough feels dry, add cold water 1 tablespoon at a time until it comes together into a smooth dough.

Avoid adding too much water.

Step 4: Chill

Shape the dough into a flat disc.

Wrap it in plastic wrap and refrigerate for 30 minutes.

This helps make the crackers crisp and easier to roll.

Step 5: Preheat the Oven

Preheat your oven to 375°F (190°C).

Line two baking sheets with parchment paper.

Step 6: Roll the Dough

Lightly flour your work surface.

Roll the dough to about ⅛ inch (3 mm) thick for crispy crackers.

The thinner the dough, the crispier the crackers.

Step 7: Cut the Crackers

Using a pizza cutter or sharp knife, cut the dough into squares about 2 inches (5 cm) wide.

Transfer them to the prepared baking sheets, leaving a small gap between each cracker.

Step 8: Dock the Crackers

Prick each cracker several times with a fork.

This prevents the crackers from puffing up during baking.

Sprinkle lightly with flaky sea salt if desired.

Step 9: Bake

Bake for 15–18 minutes, or until:

• The edges are lightly golden.
• The crackers are crisp and dry.

Rotate the baking tray halfway through baking for even browning.

Step 10: Cool

Transfer the crackers to a wire rack.

Allow them to cool completely—they’ll become even crispier as they cool.

Storage

• Store in an airtight container at room temperature for up to 1 week.
• For maximum crispness, place a paper towel in the container to absorb moisture.
• Freeze the unbaked dough for up to 3 months. Thaw overnight in the refrigerator before rolling and baking.

Tips for Perfect Onion Crackers

• Squeeze excess moisture from the grated onion if it’s very juicy.
• Roll the dough evenly to ensure all crackers bake at the same rate.
• Don’t overbake—the crackers should be lightly golden, not dark brown.
• Experiment with herbs like rosemary, thyme, or chives for extra flavor.
• Sprinkle with sesame seeds, poppy seeds, or grated Parmesan before baking for a delicious twist.
