Preheat your Blackstone griddle to medium-high or medium heat. It's important to ensure the griddle is hot before placing the hot dogs on it.
While the griddle is preheating, make a few shallow diagonal cuts along their length. This helps the hot dogs cook evenly and prevents them from curling.
Place the hot dogs on the preheated griddle, positioning them diagonally across the griddle surface. This allows for more even cooking and ensures nice grill marks.
Let the hot dogs cook for approximately 5-7 minutes, turning them occasionally to ensure even browning. You can use a spatula or tongs to flip them gently. Cook until the hot dogs are heated through and have achieved a desirable level of char and color. Using a meat thermometer, remove when the internal temperature reaches 160 degrees F.
While the hot dogs are cooking, you can also toast the buns on the griddle. Place the buns cut-side down on the griddle surface and let them toast for a minute or two until they become lightly golden and crispy.
When the hot dogs are cooked to your desired level, remove them from the griddle using tongs or a spatula. Place each hot dog into a toasted bun. Add your preferred condiments and toppings. Popular options include ketchup, mustard, relish, onions, sauerkraut, cheese, and any other toppings you enjoy.
