Portillo’s hot dogs are a Chicago institution: a steamed poppy seed bun cradling an all-beef frank, topped with yellow mustard, sweet relish, chopped onions, tomato slices, a dill pickle spear, sport peppers, and a dash of celery salt. This copycat recipe recreates that iconic flavor profile at home, using readily available ingredients and a simple steaming method that yields a juicy, snap-worthy dog every time.
Ingredients
- 8 all-beef hot dogs (natural casing recommended, e.g., Vienna Beef or Nathan’s)
- 8 poppy seed hot dog buns
- 1/2 cup (120 ml) yellow mustard
- 1/2 cup (120 ml) sweet pickle relish (neon green or regular)
- 1/2 cup (80 g) chopped white onion
- 2 medium tomatoes, sliced into 8 thin rounds each
- 8 dill pickle spears (about 4 inches / 10 cm long)
- 8 sport peppers (or banana peppers as substitute)
- 2 tsp (10 g) celery salt
- Water for steaming
Instructions
- Fill a large pot with about 1 inch (2.5 cm) of water and bring to a simmer over medium heat. Place a steamer basket or a metal colander over the pot (not touching the water). Add the hot dogs to the basket, cover with a lid, and steam for 5–7 minutes until heated through. Alternatively, simmer the hot dogs in water for 5 minutes.
- While the hot dogs steam, prepare the toppings: chop the onion, slice the tomatoes, and set out the mustard, relish, pickle spears, sport peppers, and celery salt.
- Once the hot dogs are done, place each bun in the steamer for 30 seconds to warm and soften. If you don’t have a steamer, wrap buns in a damp paper towel and microwave for 15 seconds.
- Assemble each hot dog: Place a steamed hot dog in a bun. Squeeze a line of yellow mustard along one side. Add a generous spoonful of sweet relish on the other side. Sprinkle with chopped onion. Place two tomato slices side by side on top. Lay a pickle spear alongside the hot dog (classic Chicago style is on top, but alongside works too). Add a sport pepper (or two if you like heat). Finish with a light dusting of celery salt.
- Serve immediately, with extra napkins—these are messy by design.
Tips
- Use natural-casing hot dogs: They provide that signature snap when you bite. If you can’t find them, regular all-beef franks will still taste great, just without the snap.
- Don’t skip steaming: Steaming both the dog and the bun makes the bun soft and pillowy, which is essential to the Chicago-style experience. Grilling or boiling changes the texture and flavor.
- Substitute for sport peppers: If sport peppers are unavailable, use sliced banana peppers or pickled jalapeños. They won’t have the same heat, but they add a similar vinegary kick.
- Adjust celery salt: Celery salt is potent—start with a light sprinkle and add more if you prefer. Too much can overpower the other flavors.
Serving Suggestions
Serve your Portillo’s-style hot dogs with classic sides like crinkle-cut French fries, onion rings, or a side salad. For a full Chicago experience, pair with a chocolate cake shake or a slice of chocolate cake. These hot dogs are also great for game-day gatherings or summer cookouts—just set up a topping bar so everyone can build their own.
Variations
- Maxwell Street Polish: Swap the hot dog for a Polish sausage, and top with grilled onions and yellow mustard—no relish or tomato.
- Cheese Dog: Add a slice of cheddar or a drizzle of cheese sauce (like Portillo’s cheddar sauce) over the top.
- Veggie Version: Use a plant-based hot dog and follow the same assembly. The toppings are all vegetarian, so it’s an easy swap.
- Spicy Twist: Add extra sport peppers or a drizzle of hot sauce for more heat.
Storage and Reheating
Assembled hot dogs are best eaten immediately—they don’t store well because the bun becomes soggy. If you have leftover components, store them separately: cooked hot dogs in an airtight container in the fridge for up to 3 days; chopped onions and sliced tomatoes for up to 2 days; relish, mustard, and celery salt at room temperature. To reheat leftover hot dogs, steam them again for 2–3 minutes or microwave for 30 seconds. Buns should be reheated separately if they weren’t used.
Frequently Asked Questions
Can I grill the hot dogs instead of steaming? Yes, you can grill them, but it will change the texture—grilling adds char and a smoky flavor, while steaming keeps the dog juicy and the bun soft. The classic Chicago dog is never grilled, but if you prefer that, go for it.
What are sport peppers? Sport peppers are small, green, mildly spicy peppers pickled in vinegar. They’re a staple of Chicago-style hot dogs. If you can’t find them, banana peppers or pickled jalapeños are good substitutes.
Can I use regular relish instead of sweet relish? Sweet relish is essential for the authentic flavor—it’s much sweeter and less vinegary than dill relish. If you only have dill, add a pinch of sugar to mimic the sweetness.
Why is the bun steamed? Steaming the bun makes it soft and slightly moist, which is a signature of Chicago-style hot dogs. It also helps hold the toppings without falling apart. If you don’t have a steamer, wrap buns in a damp paper towel and microwave for 15 seconds.
Can I make these ahead for a party? You can prep all the toppings ahead, but assemble just before serving to avoid soggy buns. Keep the hot dogs warm in a slow cooker with a little water, and steam the buns in batches.
What’s the best brand of hot dog? Vienna Beef is the classic Chicago choice, but any all-beef natural-casing hot dog will work well. Look for ones without artificial fillers for the best texture.
