Danish Hot Dogs with Homemade Crispy Onions

Author: Flavelo
Recipes Main Courses
The king of Danish and Norwegian street food: the 'Pølse'. While it's a simple hot dog, the toppings take it to another level. The key is the homemade fried onions (ristet løg), which add a sweet, crunchy texture. This isn't the store-bought stuff—this is fresh, golden-brown magic that people queue for in Copenhagen.

Instructions

1 ✓

Peel onions, halve them, and slice into very thin half-moons.

Tip: The thinner the onion, the crispier the result.
2 ✓

In a bowl, mix flour, paprika, salt, and sugar. Toss the onions in this mixture, then shake off excess flour using a sieve.

Tip: Sugar aids caramelization and adds a nice color.
3 ✓

Heat oil in a skillet. Add onions (in batches if necessary) and fry over medium heat, stirring often, until golden brown.

Tip: Be patient! If you fry too fast, they'll stay soggy or burn. The water needs to evaporate.
4 ✓

Remove onions to a paper towel-lined plate and spread them out to cool and crisp up.

5 ✓

Boil or grill the hot dogs according to preference.

6 ✓

Serve hot dogs topped with a mountain of homemade crispy onions and fresh parsley. (Serve in buns with mustard/remoulade for the full experience).

Recipe FAQ

Why did the onions burn?
The oil was too hot. Onions need to fry over medium heat to dehydrate and caramelize before burning.
