Creating your own Chili Cheese Dog Casserole is simple. Follow these steps to bring this comforting meal to life:

1. Preheat Oven: Start by preheating your oven to 375°F (190°C).
2. Prepare Baking Dish: Lightly grease a 9×13-inch baking dish with cooking spray or oil.
3. Layer Hot Dogs: Spread the sliced hot dogs evenly across the bottom of the baking dish.
4. Add Chili: Pour the chili over the hot dogs, ensuring all pieces are well covered.
5. Sprinkle Onions: If using, evenly distribute the diced onions on top of the chili.
6. Season: Sprinkle garlic powder, chili powder, salt, and pepper over the layers for an enhanced flavor.
7. Roll Out Crescent Dough: Open the package of crescent roll dough and unroll it. Lay it over the chili mixture, pinching the seams together to create a crust.
8. Add Cheese: Top the crescent dough with shredded cheddar cheese, evenly covering the top.
9. Bake: Place the baking dish into the preheated oven. Bake for 30-35 minutes, or until the crescent dough is golden brown and the cheese is bubbling.
10. Cool: Once baked, remove the dish from the oven and allow it to cool for about 5-10 minutes.
11. Garnish: Sprinkle fresh cilantro or green onions on top for an extra burst of flavor and color before serving.
