Preheat your oven to 350°F (175°C). This ensures that your cheese straws bake evenly.
In a mixing bowl, combine the almond flour, grated cheddar cheese, and psyllium husk or ground flaxseed. Mix well until all the dry ingredients are evenly distributed.
Crack the egg into the bowl and drizzle in the olive oil. Mix until a dough starts to form. You may need to use your hands to get everything combined thoroughly.
On a piece of parchment paper, transfer the dough and flatten it slightly. If desired, sprinkle sesame seeds on top and press them gently into the dough. Use a rolling pin to roll the dough out to about 1/4-inch thickness.
Using a sharp knife or pizza cutter, cut the rolled-out dough into strips, making them as wide or narrow as you prefer.
Transfer the strips to a baking sheet lined with parchment paper. Bake in the preheated oven for 10-15 minutes, or until the cheese straws are golden and crispy.
Once baked, allow the cheese straws to cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely. Enjoy your delicious Keto Cheese Straws as a snack or with your favorite dip!
