The Chicago hot dog is a Windy City icon: a steamed or boiled all-beef frankfurter on a poppy seed bun, loaded with yellow mustard, chopped onions, neon green relish, a dill pickle spear, tomato slices, sport peppers, and a dash of celery salt—never ketchup. This San Antonio version keeps the classic toppings but swaps the traditional poppy seed bun for a soft bolillo roll, a nod to the city’s Mexican-American baking tradition. The result is a hearty, crunchy, tangy dog that works perfectly for a quick lunch or a game-day cookout.
Ingredients
- 4 all-beef hot dogs (about 1/4 lb / 115 g each)
- 4 bolillo rolls (or 4 poppy seed hot dog buns)
- 1/4 cup (60 ml) yellow mustard
- 1/2 cup (80 g) finely chopped white onion
- 1/4 cup (60 g) neon green relish (or sweet pickle relish)
- 4 dill pickle spears (about 3 inches / 8 cm long)
- 2 Roma tomatoes, sliced into 1/4-inch (6 mm) rounds
- 8 sport peppers (or 4 pepperoncini, sliced)
- 1/2 tsp (2 g) celery salt
- Water, for steaming the hot dogs
Instructions
- Fill a large skillet or saucepan with about 1 inch (2.5 cm) of water. Bring to a simmer over medium heat. Add the hot dogs and let them simmer for 5–7 minutes, turning once, until heated through. Alternatively, you can grill them over medium heat for 5–6 minutes, turning occasionally, for a charred flavor.
- While the hot dogs cook, warm the bolillo rolls in a dry skillet over low heat for 1–2 minutes per side, or in a 300°F (150°C) oven for 5 minutes. They should be soft and slightly toasted on the inside.
- If using bolillo rolls, slice them open lengthwise, leaving one side attached. If using hot dog buns, open them as usual.
- Place each hot dog in a bun. If you steamed the hot dogs, they will be moist; if you grilled them, they will have a nice char.
- Spread 1 tablespoon (15 ml) of yellow mustard in a zigzag line along the top of each hot dog.
- Sprinkle 2 tablespoons (15 g) of chopped onion over the mustard.
- Add 1 tablespoon (15 g) of neon green relish on top of the onions.
- Place a dill pickle spear alongside the hot dog, on one side of the bun.
- Add 2–3 tomato slices on the other side of the hot dog.
- Place 2 sport peppers (or 1 sliced pepperoncini) on top of the tomato slices.
- Finish with a pinch of celery salt (about 1/8 tsp / 0.5 g) over everything.
- Serve immediately, while the bun is warm and the toppings are fresh.
Tips
- Substitutions: If you can’t find neon green relish, use sweet pickle relish and add a drop of green food coloring (optional). Sport peppers are hard to find outside the Midwest; use sliced pepperoncini or pickled jalapeños for a similar heat.
- Bun choice: Bolillo rolls are sturdier than standard hot dog buns, so they hold up better with all the toppings. If you use a regular bun, toast it lightly to prevent sogginess.
- Don’t skip the celery salt: It adds a subtle herbal note that ties everything together. If you don’t have it, mix 1/2 tsp salt with 1/4 tsp celery seed, crushed.
- Common mistake: Adding ketchup is a classic faux pas in Chicago. The mustard and relish provide enough tang; ketchup would overpower the delicate balance.
Serving Suggestions
Serve these hot dogs with a side of crispy french fries or potato chips. A cold glass of lemonade or a Mexican Coke (made with cane sugar) pairs perfectly. For a full San Antonio spread, add a side of charro beans or elote (Mexican street corn).
Variations
- Grilled version: Grill the hot dogs over medium-high heat for 5–6 minutes, turning occasionally, until they have nice char marks. This adds a smoky flavor that complements the toppings.
- Spicy version: Add a drizzle of hot sauce or a few slices of fresh jalapeño along with the sport peppers for extra heat.
- Cheese version: Sprinkle shredded cheddar or crumbled cotija cheese over the hot dog before adding the remaining toppings. This is not traditional, but it’s a delicious fusion.
- Vegetarian version: Use a plant-based hot dog (like those from Beyond Meat or Field Roast) and follow the same cooking instructions. Cook to 165°F (74°C) as per package directions.
Storage and Reheating
These hot dogs are best eaten immediately, as the toppings can make the bun soggy. If you have leftovers, store the cooked hot dogs and buns separately in airtight containers in the refrigerator for up to 3 days. To reheat, warm the hot dogs in simmering water for 2–3 minutes or in the microwave for 30 seconds. Toast the buns in a dry skillet for 1 minute. Reassemble with fresh toppings—do not reheat the assembled hot dog, as the vegetables will become limp.
Frequently Asked Questions
Can I use regular hot dog buns instead of bolillo rolls? Yes, you can. Standard buns work fine, but they are less sturdy. Toast them lightly to help them hold up under the toppings.
What are sport peppers and where can I find them? Sport peppers are small, green, spicy peppers packed in vinegar. They are a staple of the Chicago dog. If you can’t find them in your local grocery store, look in the international aisle or online. Pepperoncini or pickled jalapeños are good substitutes.
Is it okay to add ketchup? In Chicago, ketchup on a hot dog is considered a culinary sin. The mustard, relish, and celery salt provide the perfect balance of flavors. You can add ketchup if you like, but it will change the character of the dish.
Can I make these ahead of time? You can cook the hot dogs and prep the toppings in advance, but assemble just before serving. Store the cooked hot dogs in the refrigerator for up to 3 days and reheat as described. The toppings should be prepared fresh.
What is the best way to cook the hot dogs? Steaming is traditional and keeps them juicy. Grilling adds a smoky flavor. Both are great—choose based on your preference and the weather.
Can I freeze the cooked hot dogs? Yes, cooked hot dogs freeze well for up to 2 months. Wrap them individually in plastic wrap and place in a freezer bag. Thaw in the refrigerator overnight and reheat in simmering water.
