Chicago Hot Dog Supplies: The Full Ingredient List

The Chicago-style hot dog is a Windy City icon: a steamed all-beef frankfurter on a poppy seed bun, loaded with yellow mustard, neon green relish, chopped onions, tomato wedges, pickle spear, sport peppers, and a dash of celery salt. It’s a symphony of textures and flavors—snappy, tangy, salty, and crunchy—all held together by a soft bun. This recipe gives you the exact supplies and step-by-step assembly to build an authentic version at home, with clear substitutions for hard-to-find items.

Ingredients

4 all-beef hot dogs (natural casing preferred, about 1/4 lb / 115 g each)
4 poppy seed hot dog buns (soft, not toasted)
1/2 cup (120 ml) yellow mustard
1/3 cup (80 ml) neon green sweet pickle relish (or regular sweet relish with a drop of green food coloring)
1/2 medium white onion, finely chopped (about 1/2 cup / 75 g)
2 Roma tomatoes, cut into thin wedges (about 8 wedges per tomato)
4 dill pickle spears (each about 3 inches / 7.5 cm long)
8 sport peppers (small, hot, pickled peppers; substitute with sliced jalapeños if needed)
1 teaspoon celery salt (or celery seed, crushed)
Water, for steaming

Instructions

Fill a pot wide enough to hold the hot dogs with about 1 inch (2.5 cm) of water. Bring to a simmer over medium heat (about 180°F / 82°C, not boiling).
Place the hot dogs in the simmering water. Cover and let them steam for 5–8 minutes, until heated through. If using natural casing, the skin should feel snappy when you pinch it. Alternatively, you can grill or pan-fry the hot dogs for a smoky flavor, but steaming is traditional.
While the hot dogs cook, prepare the toppings: chop the onion, slice the tomatoes, and drain the pickle spears and sport peppers.
Steam the buns: place them cut-side down in a steamer basket over the simmering water for 1–2 minutes, until soft and warm. If you don’t have a steamer, wrap them in a damp paper towel and microwave for 15–20 seconds.
Place each hot dog in a bun. The bun should be soft, not toasted.
Add the toppings in the classic order: yellow mustard in a zigzag line, then a generous spoonful of neon green relish, then a sprinkle of chopped onion, then two tomato wedges along one side, then a pickle spear on the other side, and finally two sport peppers on top.
Finish with a light dusting of celery salt over the entire dog. Serve immediately.

Tips

Don’t skip the poppy seed bun: It’s a key part of the experience. If you can’t find one, brush a plain bun with melted butter and sprinkle with poppy seeds before steaming.
Keep the order: The classic order isn’t just tradition—it ensures each bite has a balance of flavors. Don’t put the pickle under the dog; it should be on the side.
Substitute for sport peppers: If you can’t find sport peppers, use sliced pickled jalapeños. They’re milder but still add heat and tang.
Don’t use ketchup: In Chicago, ketchup is considered a faux pas. Stick to yellow mustard for the authentic taste.

Serving Suggestions

Serve the hot dogs immediately after assembling, with plenty of napkins. They’re perfect for a casual lunch or dinner, and pair well with classic sides like French fries, onion rings, or a simple potato salad. For a full Chicago-style meal, add a side of giardiniera (spicy pickled vegetables) and a cold soda or beer (for adults).

Variations

Veggie version: Use a plant-based hot dog (e.g., tofu or pea protein) and steam it the same way. All the classic toppings work great.
Cheese dog: Add a slice of cheddar or a drizzle of cheese sauce under the toppings for a heartier version.
Spicy twist: Add extra sport peppers or a dash of hot sauce for more heat.
Grilled bun: If you prefer a crispy texture, grill the buns briefly on a buttered skillet, but note this deviates from the traditional soft bun.

Storage and Reheating

Assembled hot dogs are best eaten immediately. If you have leftover components, store them separately: cooked hot dogs in an airtight container in the fridge for up to 3–4 days; chopped onions and tomato wedges in separate containers for up to 2 days. Do not store assembled dogs—the bun will become soggy.

To reheat, steam the hot dogs again in simmering water for 3–5 minutes, or microwave on a plate for 30–45 seconds. Reheat buns by steaming for 30 seconds or wrapping in a damp paper towel and microwaving for 15 seconds. Always reheat leftovers to an internal temperature of 165°F (74°C) for safety.

Frequently Asked Questions

What are sport peppers? Sport peppers are small, green, pickled chili peppers that are moderately hot. They’re a staple in Chicago-style hot dogs. If you can’t find them, use sliced pickled jalapeños or even banana peppers for a milder kick.

Can I use regular relish instead of neon green? Yes, but the taste will be slightly different. Neon green relish is sweet and has a bright, almost artificial flavor that’s distinct. To mimic it, add a drop of green food coloring to regular sweet relish.

Why no ketchup? It’s a regional tradition—ketchup is seen as overpowering the other flavors. The mustard, relish, and celery salt are meant to shine. You can add ketchup if you like, but it won’t be authentic.

Can I grill the hot dogs instead of steaming? Yes, grilling adds a smoky char, but it changes the texture. Steaming keeps the casing snappy and the dog juicy, which is the traditional method. If you grill, do it over medium heat for 5–7 minutes, turning often.

What if I don’t have a steamer? You can simmer the hot dogs in water as described, and for the buns, wrap them in a damp paper towel and microwave for 15–20 seconds. That works perfectly.

How do I keep the buns from getting soggy? The key is to add the toppings just before serving, not earlier. Also, drain the pickle spear and sport peppers well before placing them on the dog. A slightly dry bun is better than a soggy one.
