Prepare the Dry Ingredients: In a large mixing bowl, whisk together the flour, salt, and freshly ground black pepper until evenly combined. This dry base will season the dough and give it that signature peppery bite.
Incorporate the Butter: Add the cold, cubed butter to the flour mixture. Using a pastry blender or your fingertips, cut and rub the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces of butter still visible. This ensures a flaky texture in the final cheese straws.
Add Cheese and Bind: Stir in the shredded sharp Cheddar cheese, distributing it evenly throughout the mixture. Gradually drizzle in cold water, one tablespoon at a time, stirring gently after each addition. Stop once the dough starts to come together but isn’t sticky— it should hold when pressed but still be slightly crumbly.
Chill the Dough: Form the dough into a flat disk, wrap it tightly in plastic wrap, and refrigerate for at least 30 minutes. Chilling firms up the butter and makes the dough easier to roll out.
Roll Out and Cut Straws: On a lightly floured surface, roll the dough out into a rectangle approximately 1/4 inch thick. Using a sharp knife or pizza cutter, slice the dough into narrow strips about 1/2 inch wide and 3–4 inches long to create the classic cheese straw shape.
Bake to Golden Perfection: Preheat your oven to 375°F (190°C). Place the cut strips onto a rimmed baking sheet lined with parchment paper or a silicone mat, spacing them about 1 inch apart. Bake for 10–12 minutes or until the straws turn a beautiful golden brown and the edges crisp up.
Cool and Serve: Transfer the baked cheese straws to a wire cooling rack and let them cool completely. This helps maintain their crisp texture. Once cooled, serve immediately or store in an airtight container for up to one week.
