Kartoffelsalat is a traditional German potato salad. It's a delicious dish made with boiled potatoes, onions, and a tangy dressing typically made with vinegar, oil, mustard, and herbs. Some variations also include bacon, pickles, tomatoes, radish or mayonnaise for added flavor. It's a popular side dish that complements many meals.
Start by boiling the potatoes in a large pot of salted water until they are fork-tender. This usually takes about 15-20 minutes, depending on the size of the potatoes.
While the potatoes are boiling, prepare the dressing. In a small bowl, whisk together the vinegar, vegetable oil, mustard, salt, and pepper until well combined.
Once the potatoes are cooked, drain them and let them cool slightly. Then, peel the potatoes and cut them into bite-sized pieces. Place them in a large bowl.
Add the chopped onion to the potatoes, and pour the dressing over the top. Gently toss everything together until the potatoes are evenly coated with the dressing.
Allow the Kartoffelsalat to sit for at least 30 minutes, or even better, refrigerate it for a few hours to let the flavors meld together.
Just before serving, give the potato salad a final stir and adjust the seasoning if needed. You can also garnish it with fresh herbs or radish for an extra touch of freshness and color.
