01 - Place beef in the freezer for 1 hour to firm up, facilitating thin slicing.
02 - Cut beef against the grain into thin strips approximately ⅛ to ¼ inch thick.
03 - Combine soy sauce, Worcestershire sauce, black pepper, brown sugar, smoked paprika, onion powder, garlic powder, and crushed red pepper flakes in a large bowl. Stir to blend thoroughly.
04 - Submerge beef strips in the marinade, ensuring full coverage. Cover bowl and refrigerate for a minimum of 8 hours or overnight.
05 - Set oven to 160°F (70°C) or ready your dehydrator for drying.
06 - Place wire racks on baking sheets or use dehydrator trays. Arrange marinated beef strips in a single layer, keeping space between each to allow air circulation.
07 - Dry in the oven (keep door slightly ajar) or dehydrator for 4 to 6 hours until jerky is dry yet retains slight pliability.
08 - Allow jerky to cool completely before transferring to an airtight container for storage.
