Recipe FAQs

What type of cheese works best for this dish?

Sharp cheddar cheese is ideal for its meltability and flavor, but Monterey Jack or pepper jack can add a mild or spicy twist.

Can I use a vegetarian substitute for the beef hot dogs?

Yes, plant-based or turkey hot dogs work well to lighten the dish while maintaining a similar texture.

How do I prevent the buns from becoming soggy?

Brushing the buns with melted butter before assembling helps create a barrier, keeping them crisp during baking.

Is it necessary to use fresh onions?

Fresh yellow onions add sweetness and depth, but caramelized or sautéed onions can also enhance flavor.

What are good garnish options for serving?

Chopped fresh chives or green onions and a dollop of sour cream provide a bright, creamy contrast to the rich, cheesy layers.
