This recipe for pickled red onions is really easy to make and they are super delicious. At first we wasn’t sure where to use pickled red onions – but we quickly realized that they can be used everywhere where we use our cucumber salad or just normal pickles. They go perfectly as topping for burgers or hotdogs. We have also used them as a side dish for cooked pork and beef. The recipe only consist of 4 different ingredients, red onions, vinegar, sugar and some pepper, and it’s so easy to make – you dissolve the sugar in the vinegar, slice the onions and let them soak in the vinegar/sugar mixture for some time and that’s it! Super simple! Besides that great taste, the red onions get a beautiful pink color after some time in the vinegar mixture.
Pickled Red Onions
2 glass jars
Preparation time: 15 minutes
Danish title: Syltede rødløg
Ingredients:
3 red onions
4 dl (1.75 cups) vinegar
1 dl (0.5 cup) sugar
Some pepper grains
Instruction:
Step 1: Pour the sugar and the vinegar into a bowl and stir until all the sugar has dissolved.
Step 2: Clean a glass jar using boiling water. This will kill all bacteria and make sure that the onions stay fresh longer.
Step 3: Slice the onions and put them in the glass jar.
Step 4: Pour the vinegar/sugar mixture in the jar and add some pepper grains.
Step 5: Place the jar in the fridge for some hours and they are done. Keep the jar refrigerated.
Tip: Serve them as topping for burgers, hotdogs or just as a side dish for pork or beef meat.

May 13, 2015 at 12:53 amHelp! My mom was from Denmark. When I was little she made pickled sweet red onions, but I can’t find a recipe. I recall her adding yellow mustard and it seems that there was a bit of oil in the jar…not just vinegar.
Do you know of this recipe?

June 25, 2018 at 11:04 amWhat kind of vinegar should be used? Thanks.
Kim Nielsen says
June 26, 2018 at 6:57 amHI. You should use the normal white vinegar which can be found in most supermarkets. It’s clear and colorless. Sometimes it is called ‘pickling vinegar’. I hope this answers your question.

September 15, 2018 at 4:56 pmI have some lager vinegar, would this work also? I used it all the time when I lived in Denmark and find it has a good flavor for pickles.
