Prepare Beef: Slice the beef into thin strips. Partially freezing the meat can make this easier.
Combine Marinade Ingredients: In a bowl, whisk together teriyaki sauce, soy sauce, brown sugar, honey, minced garlic, grated ginger, onion powder, and black pepper.
Marinate Beef: Place the beef strips in the marinade, ensuring they are well coated. Refrigerate for at least 4 hours, or overnight for deeper flavor.
Oven Preparation: Preheat your oven to 175°F (80°C). Line a baking sheet with parchment paper and place a wire rack on top.
Arrange Beef Strips: Lay the marinated beef strips on the wire rack, ensuring they don't overlap.
Bake: Bake for 3 to 4 hours, or until the jerky is dry and firm but still pliable.
Cool and Store: Let the jerky cool completely before storing in an airtight container.
