Air Fryer Hot Dog Melt

Ingredients

• Quality Hot Dogs: 4 all-beef hot dogs or your favorite frankfurters
• Hot Dog Buns: 4 soft, fresh hot dog buns
• Cheddar or Mozzarella Cheese: 1. 5 cups, freshly shredded (shredded cheddar provides a sharp, savory punch, while mozzarella offers an incredible gooey pull)
• Yellow Onion: 1/2 medium onion, thinly sliced
• Butter: 1 tablespoon, melted (for brushing the buns and onions)
• Yellow Mustard: 2 tablespoons
• Ketchup or Relish: Optional, for serving
• Crispy Fried Onions: 1/4 cup, for an optional extra crunch topping

Instructions

Step 1: Preheating and Onion Sautéing

1. Preheat your air fryer to 370°F (190°C) for about 3 minutes so it is hot and ready for optimal crisping.
2. In a small skillet over medium heat, melt half of the butter and sauté the thinly sliced yellow onions until they are soft, translucent, and lightly caramelized (about 4–5 minutes). Set aside.

Step 2: Preparing the Hot Dogs and Buns

1. Take each hot dog and make a lengthwise slit down the center, cutting about three-quarters of the way through (do not cut all the way through). This “butterfly” cut helps the hot dog sit flat and creates a pocket for toppings.
2. Place the hot dog buns open inside your air fryer basket. Lightly brush the inside of each bun with the remaining melted butter to protect it from becoming soggy and to promote a golden crunch.
3. Place one butterflied hot dog inside each buttered bun.

Step 3: Filling and Layering

1. Spoon a portion of the caramelized onions directly into the slit of each hot dog.
2. Drizzle a small line of yellow mustard inside the hot dog and over the onions.
3. Pack the freshly shredded cheddar or mozzarella cheese tightly into and over the top of the hot dogs, filling the buns generously so the cheese cascades down the sides.

Step 4: Air Frying to Melted Perfection

1. Carefully transfer the assembled hot dog melts into the air fryer basket (work in batches if your air fryer is smaller to avoid overcrowding).
2. Cook at 370°F (190°C) for 6 to 8 minutes . Keep a close eye on them around the 5-minute mark to ensure the cheese melts into a bubbling, golden crown and the edges of the buns turn perfectly crisp without burning.

Step 5: Final Presentation and Serving

1. Remove the hot dog melts gently from the air fryer using tongs.
2. Top with a sprinkle of crispy fried onions for added texture.
3. Serve immediately while the cheese is hot, gooey, and stretching with every bite. Pair with a side of potato chips, a crisp green salad, or air-fried french fries.
