In a large mixing bowl (or a zip-top bag), combine the potatoes, peppers, onions, garlic, and oregano. Drizzle with olive oil and season generously with salt and pepper. Toss until everything is evenly coated.
Option 1: In the Oven
Preheat your oven to 425°F (220°C).
Spread the mixture on a large rimmed baking sheet in a single layer.
Roast for 30–35 minutes, stirring halfway, until the potatoes are golden and crispy, and the peppers and onions are soft and caramelized.
Meanwhile, pan-sear or grill the hot dogs until nicely browned and hot all the way through.
Once roasted, remove the garlic cloves from their peels (they’ll slip right out), mash them with a fork, and stir into the roasted veggies and potatoes.
Taste and adjust seasoning — a sprinkle of salt and a little more oregano really bring it to life.
Option 2: On the Grill
Preheat your grill to medium-high (425°F / 220°C).
Toss the potatoes with olive oil, salt, pepper, and oregano. Spread them out on a grill-safe pan or foil tray and cook for 20–25 minutes, stirring occasionally, until tender and golden.
Add the peppers, onions, and garlic (sealed in a foil packet with olive oil, salt, and pepper) to the grill for the last 15 minutes.
Grill the hot dogs directly over the heat for about 5 minutes, turning until they’re beautifully charred.
Remove everything from the grill, mash the roasted garlic, and toss it with the potato and pepper mixture.
Toast your hoagie rolls or buns until warm and slightly crisp. Place a hot dog in each bun and pile on a generous scoop of the roasted potato-pepper-onion mixture.
These Italian Hot Dogs are hearty, garlicky, and full of that sweet-savory balance from the roasted veggies and oregano. Serve with a side of extra crispy potatoes (because there’s no such thing as too many).
Notes
Erren’s Top Tips
You can cook the hot dogs stovetop, on an outdoor gas grill, or broil them on a foil-lined baking sheet for 2 to 4 minutes, turning once, until lightly charred.
Give the potatoes space on the pan. Crowding leads to steaming instead of crisping
Cut the potatoes evenly so they cook at the same rate
Add extra olive oil if things look dry halfway through roasting
Taste before serving and adjust with salt or even a squeeze of lemon for brightness
If you want extra crisp, broil for the last 2 to 3 minutes
Variations & Add-Ins
Add sliced Italian sausage along with the hot dogs for a heartier version
Toss in chili flakes for a little heat
Add shredded mozzarella or provolone on top and melt before serving
Mix in sautéed mushrooms for a deeper savory flavor
Storage & Freezing
Store the potato and pepper mixture separately from the buns and hot dogs in an airtight container in the fridge for up to 3 days.Reheat in a skillet or oven to bring back crispness.Freezing is not recommended as the potatoes can become grainy and soft when thawed.
