Begin by preheating your oven to 350°F (180°C). Arrange the 8 hot dog buns, still attached, in a 9 x 13-inch (22 x 33-cm) baking dish. Carefully carve out a rectangular shape in each bun, ensuring that you maintain a 1-centimeter margin from the edges. Gently press down the removed bread pieces to create a compact base within each bun, particularly at the bottom edges. This technique will enhance the space available for the fillings and minimize mess.

In a small bowl, combine the melted butter, minced garlic, and finely chopped parsley. Brush this flavorful mixture generously over the hollowed-out insides of the buns. Place the buns in the oven to bake for approximately 5 minutes. This toasting process will firm up the sides of the buns, preventing them from collapsing under the weight of the delicious fillings.

Next, insert a slice of cheddar cheese into each bun, followed by a spoonful of chili. Nestle a hot dog snugly atop the chili in each bun, and add an additional layer of chili on top. Bake the assembled dish in the preheated oven for 20-25 minutes, or until the cheese achieves a golden-brown hue and the chili begins to bubble and brown.

Finally, remove from the oven, garnish with fresh parsley, and slice the hot dog boats along their connected seams for serving. Enjoy your Chili Cheese Dog Bake!
