Step 1: Preheat the Air Fryer

Start by preheating your air fryer to 375°F (190°C). This takes about 3 minutes and helps ensure the buns toast evenly and the cheese melts properly.

Tip: Preheating is especially important for recipes where timing and crispiness matter.

Step 2: Cook the Hot Dogs

• Place hot dogs directly in the air fryer basket — no oil necessary.

• Cook for 4–5 minutes, turning once halfway through for even crisping.

• Remove from the basket and set aside.

Want a grilled texture? Lightly score the hot dogs diagonally with a knife before air frying. It gives them character and added surface crispness.

Step 3: Butter the Buns

• Gently open each hot dog bun and spread butter on both the inside and outside surfaces. This ensures that when they cook in the air fryer, they’ll develop a beautifully browned, crispy texture.

Pro tip: Use real butter for best flavor. Avoid margarine or low-fat spreads, which don’t toast as well.

Step 4: Assemble the Grilled Cheese Hot Dogs

• Place 1 slice of cheese along the bottom interior of each buttered bun.

• Add a cooked hot dog on top of the cheese slice.

• Place another slice of cheese on top of the hot dog.

Now you have the perfect sandwich structure: cheese-hot dog-cheese, hugged by buttery bread.

Step 5: Air Fry the Sandwiches

• Place your assembled grilled cheese hot dogs in the air fryer basket.

• Ensure they’re spaced apart — don’t stack or overlap them.

• Air fry at 375°F (190°C) for 4–6 minutes.

You’re looking for golden-brown buns and melted, bubbly cheese. Peek halfway through to prevent over-browning.

Step 6: Add Toppings and Serve

Carefully remove the sandwiches with tongs or a spatula. Let them rest for a minute (cheese will be hot). Add your desired toppings — this is where you get creative!
