Danish Hot Dog: Classic Toppings and Easy Steps

A Danish hot dog pairs a grilled or griddled sausage with a warm bun and a distinctive mix of crisp onions, tangy pickles, ketchup, mustard, and remoulade. This popular Danish street-food style balances smoky, savory sausage with cool, crunchy toppings; the exact toppings and bun style vary from vendor to vendor.

Ingredients

4 Danish-style hot dog sausages, about 1 lb (450 g) total; choose fully cooked sausages or fresh pork sausages that can be cooked through
4 hot dog buns, about 4 oz (115 g) total
1 medium yellow onion, about 5 oz (140 g), finely chopped
1 tablespoon (15 ml) neutral oil, such as canola oil
4 tablespoons (60 ml) remoulade sauce, preferably Danish-style
4 teaspoons (20 ml) ketchup
2 teaspoons (10 ml) mild yellow mustard or Danish sweet mustard
8 thin slices (about 2 oz/55 g) pickled cucumber, drained
2 tablespoons (30 ml) crispy fried onions
Water for simmering, if using the stovetop method

Instructions

Prepare the toppings. Chop the onion finely and drain the pickle slices. Keep the remoulade, ketchup, mustard, and crispy onions close at hand so the hot dogs can be assembled while warm. If you do not have Danish remoulade, use a good-quality creamy remoulade; its flavor may be less sweet and curry-spiced.
Cook the fresh onion. Heat the oil in a small skillet over medium heat. Add the chopped onion and cook for 5 to 7 minutes, stirring often, until soft and lightly golden. Transfer to a small bowl. Leave the crispy fried onions uncooked for the final topping.
Cook the sausages. For fully cooked sausages, grill or pan-cook over medium heat for about 6 to 8 minutes, turning often, until evenly hot and browned. If using fresh pork sausages, cook gently, turning regularly, until a thermometer inserted into the center reads 160°F (71°C); this is the USDA FSIS safe minimum for ground meat. Avoid splitting the casings by keeping the heat moderate. If using water, bring a shallow pan to a gentle simmer, add the sausages, and cook according to the package directions; brown them briefly in a skillet or on the grill afterward if desired.
Warm the buns. During the last minute of cooking, warm the buns cut-side down on the grill or in a dry skillet until soft and just lightly toasted. Do not leave them unattended; they can scorch quickly. Alternatively, wrap them in a clean kitchen towel for a few minutes to warm them without browning.
Assemble and serve. Place one sausage in each bun. Add a spoonful of cooked onion, then arrange two pickle slices along the sausage. Drizzle with remoulade, ketchup, and mustard, and finish with crispy fried onions. Serve right away, while the sausage is hot and the onions remain crisp.

Tips

Choose the sausage thoughtfully. Danish hot dog stands often use long, slender sausages, sometimes dyed red, but color is not essential to the dish. A good-quality frankfurter or all-beef hot dog is an easy substitute; it will taste different but works with the same toppings.
Look for Danish remoulade. It is typically a creamy, mildly sweet sauce with chopped pickles and spices, sometimes including curry. If it is unavailable, combine equal parts mayonnaise and relish with a small pinch of curry powder. This quick substitute is less complex, so season it to taste rather than adding a lot at once.
Keep the toppings balanced. Remoulade and ketchup can make a bun soggy if applied too heavily. Use a thin drizzle, drain pickles well, and add crispy onions immediately before serving.
Use the package directions for packaged sausages. Fully cooked hot dogs need reheating, while fresh sausages require thorough cooking. Use a thermometer for fresh pork sausage, and do not rely only on browned casings to judge doneness.

Serving Suggestions

Serve the hot dogs as soon as they are assembled, with extra remoulade and pickles at the table. For a casual meal, pair them with Danish-style cucumber salad, a crisp green salad, or oven-baked fries. A simple cabbage slaw also works well because its fresh crunch offsets the rich sausage and creamy sauce. If you are serving a group, set out the toppings separately and let everyone build a hot dog just before eating; this keeps the buns from sitting under sauce.

Variations

Use a different sausage: Substitute a beef frank, chicken sausage, or vegetarian sausage. Cook each according to its package directions and apply the appropriate safe-temperature guidance for the product.
Make it less sweet: Use a sharper mustard and reduce the ketchup. A little extra pickle can add tang without changing the basic style.
Try a crunchy onion finish: Use only crispy fried onions for speed, or combine them with the soft cooked onion for contrasting textures.
Adjust the pickles: Danish-style pickled cucumber is a natural choice. Thinly sliced dill pickle is an easy substitute, though it tends to be saltier and less sweet.

Storage and Reheating

For best texture, store cooked sausages separately from buns and toppings. Refrigerate cooked sausages and sautéed onions within 2 hours in covered containers; they keep for 3 to 4 days at 40°F (4°C) or colder. Keep opened condiments refrigerated according to their labels. Store buns at room temperature only if the package permits; otherwise follow the package guidance. Assemble the hot dogs just before serving, since dressed buns become soggy.

Reheat sausages in a covered skillet over low heat with a spoonful of water, turning until steaming hot, or microwave them in short intervals. Leftovers must reach 165°F (74°C) when reheated. Warm buns separately, and add fresh pickles, remoulade, and crispy onions after heating. Discard perishable food left at room temperature for more than 2 hours, or 1 hour when the temperature is above 90°F (32°C).

Frequently Asked Questions

What makes a hot dog Danish?
A Danish hot dog is generally a sausage in a bun topped with some combination of remoulade, ketchup, mustard, pickled cucumber, and onions. The distinctive creamy remoulade and the mix of soft and crispy onions help give it its familiar Danish street-food character.

Do I need a red Danish sausage?
No. Red sausages are associated with Danish hot dog stands, but they can be difficult to find and are not necessary for a home version. Use a frankfurter or another hot dog sausage you enjoy, and follow its package directions.

Can I make the toppings ahead?
Yes. Chop the onion and drain the pickles several hours ahead, then refrigerate them in separate covered containers. Cooked onions can also be made ahead and refrigerated for 3 to 4 days. Keep crispy onions sealed at room temperature according to their package instructions, and assemble just before serving.

Can I cook the sausages in water instead of grilling?
Yes. Gently simmering is a practical way to heat sausages without charring them. Avoid a hard boil, which can split the casings. For extra color, briefly brown fully heated sausages in a skillet or on a grill afterward.

How do I keep the bun from getting soggy?
Warm the bun shortly before serving, drain the pickles, and use a moderate amount of sauce. Put the sausage and toppings into the bun at the last moment rather than letting assembled hot dogs sit. Keep extra sauce on the side for anyone who wants more.

Can I make these without remoulade?
Yes. Use mayonnaise mixed with relish and a small pinch of curry powder, or serve mayonnaise and mustard separately. The result will not taste exactly like Danish remoulade, but the pickles, onions, and sausage will still make a satisfying hot dog.
