Using a mandoline or very sharp knife, thinly slice the onion. Add the sliced onions to a 16-ounce jar.
1 large red onion
Add the vinegar, sugar, and salt to a small saucepan. Over medium heat, stir until the sugar and salt are dissolved.
1.5 cups white vinegar, 1 tsp salt, 1 tbsp sugar
Pour the heated vinegar mixture into the jar, over the onions. Then add the peppercorns. Let everything cool for 5 minutes before placing the top on the jar. You’ll have pickled onions in about 10 minutes! Store them in the refrigerator for up to 2 weeks.

Notes
While you can use them after about 10 minutes, I find pickled onions to be best a few hours later.
Make sure you're using whole peppercorns, not ground pepper! If you don't have them you can leave them out, it won't make or break the recipe!
