Whisk the egg. Add the almond flour and sea salt, stirring bring together. Knead a few times in the bowl until dough comes together well. Roll the dough into a ball and form the ball into a disk.
Place the dough between two sheets of parchment paper. Using a rolling pin, roll the dough out between 1/16" and 1/8" thickness.
Remove the top paper. Using a cookie cutter, pizza cutter or knife, cut into your desired shape, approximately 2-inches in diameter. Save the scraps and re-roll it to get more crackers. Move the cut crackers, along with the parchment they are on, to the baking sheet.
Sprinkle a bit over Everything Bagel Blend on top of each cracker.
Bake the crackers for 12 to 14 minutes, until lightly golden brown, rotating the pan once. Watch carefully from 8 minutes on, so they don't burn. The crackers around the edge of the pan will brown much more quickly, so those can be pulled sooner to the cooling rack and then return the pan back to the oven to finish baking the remaining center crackers.
Allow the crackers to cool on the pan for 5 minutes then transfer to a cooling rack and cool completely, before transferring them to an airtight container or bag and store at room-temperature.
