In New Jersey, an Italian hot dog is a fried sandwich—not a hot dog with marinara or generic Italian seasoning. This Italian hot dog recipe makes four sandwiches with crisp potatoes, tender peppers and onions, browned hot dogs, and warm pizza bread or sturdy rolls.
Italian Hot Dog: New Jersey’s Regional Sandwich
The New Jersey regional dish combines fried vegetables and hot dogs in a large, chewy roll. The potatoes are part of the sandwich, not a side dish: they fill the bread first, followed by the peppers, onions, and browned hot dog pieces. Pizza bread is traditional, but a sturdy 6-inch sub roll works well if it can hold the filling without tearing.
Plan for about 15 minutes of preparation and 25 minutes of cooking, for a total of roughly 40 minutes. Keep the potatoes in a single layer whenever possible so they fry instead of steaming.
Italian Hot Dog Recipe: Ingredients and Yield
Yield: 4 sandwiches
- 1 1/2 pounds russet potatoes, peeled and cut into 1/2-inch sticks
- 2 medium green bell peppers, seeded and sliced into strips
- 1 large yellow onion, halved and thinly sliced
- 4 standard beef or pork hot dogs
- 4 small pizza breads or sturdy 6-inch sub rolls
- 1/2 cup neutral frying oil, such as canola or peanut, divided
- 1 1/2 teaspoons kosher salt, divided
- 1/2 teaspoon freshly ground black pepper
Rinse the cut potatoes under cold water, then dry them very thoroughly with towels. Excess water causes hot oil to splatter and keeps the potatoes from browning. Split each hot dog lengthwise, then cut it in half so the pieces fit easily into the bread.
Fry the Potatoes Until Crisp
- Heat 1/4 cup of the oil in a large, heavy 12-inch skillet over medium-high heat until it shimmers. Add the potatoes in one layer. If they crowd the pan, fry them in two batches.
- Cook for 10 to 14 minutes, turning every few minutes, until the edges are deep golden brown and the centers are tender when pierced. Add a little more oil if the pan becomes dry.
- Transfer the potatoes to a rack or a paper towel-lined plate. Season immediately with 3/4 teaspoon of the salt and the black pepper. Keep them uncovered so trapped steam does not soften the crust.
The potatoes should be browned outside but still fluffy inside. If they look pale and wet, the pan is overcrowded or the oil is not hot enough; give them more space and allow the oil to heat before continuing.
Add Peppers, Onions, and Hot Dogs in Order
- Add 1 tablespoon of oil to the skillet, then add the peppers and onions. Fry for 7 to 9 minutes, stirring occasionally, until softened and browned at the edges. Season with the remaining 3/4 teaspoon salt.
- Remove the vegetables to a bowl. Add another tablespoon of oil if the skillet is dry, then place the split hot dogs cut-side down. Cook for 2 to 3 minutes, turn, and cook for another 2 to 3 minutes, until browned and heated through.
- Return the potatoes and vegetables to the skillet for 1 minute. Toss gently so the fillings warm together without breaking the potatoes.
Cooking in this order preserves the potato crust, gives the vegetables time to caramelize, and lets the hot dogs pick up the seasoned oil without drying out. Do not add the hot dogs at the beginning; they can overcook while the raw potatoes finish.
Assemble the Sandwich in Pizza Bread or a Sturdy Roll
- While the filling finishes, slice each pizza bread or roll open lengthwise. Place it cut-side down in the warm skillet for 1 to 2 minutes, just until lightly toasted and flexible. Avoid hard toasting, which makes the bread crack.
- Pack each bread with one-quarter of the fried potatoes, pressing them gently into the bottom so they create a firm base.
- Nestle two hot dog pieces into each sandwich, then pile the fried peppers and onions over and around them. Add any remaining potatoes on top or at the sides.
- Serve immediately, while the bread is warm, the vegetables are tender, and the potato edges are still crisp.
