Instructions

Step 1: Cook the Potatoes

Place the halved baby potatoes in a large pot and cover with cold salted water. Bring to a boil, then reduce to a simmer and cook for about 10–15 minutes until fork-tender. Be careful not to overcook them. Drain and let them cool slightly so they hold their shape when mixed.

Step 2: Cook the Bacon

In a skillet over medium heat, cook the bacon until crispy. Transfer to a paper towel-lined plate and let it cool, then crumble into small pieces. Reserve a little bacon fat in the pan for extra flavor.

Step 3: Caramelize the Onions

In the same skillet, add butter and olive oil along with the sliced onions. Cook over medium-low heat, stirring occasionally, for about 15–20 minutes until the onions are soft, golden brown, and deeply caramelized. This step builds the signature French onion flavor, so take your time.

Step 4: Prepare the Dressing

In a bowl, whisk together mayonnaise, sour cream, Dijon mustard, apple cider vinegar, Worcestershire sauce, garlic powder, salt, and pepper until smooth and creamy. Taste and adjust seasoning if needed.

Step 5: Combine the Salad

In a large mixing bowl, add the warm potatoes, caramelized onions, diced red onion, and most of the bacon. Pour the dressing over everything and gently fold until the potatoes are well coated without breaking apart.

Step 6: Finish and Chill

Sprinkle the remaining bacon and fresh parsley on top. Let the salad rest for at least 20–30 minutes before serving so the flavors can fully develop. You can serve it slightly warm or chilled depending on your preference.

FAQs

Can I make French onion potato salad ahead of time?
Yes, this salad is actually even better when made ahead. Preparing it a few hours in advance or even the day before allows the potatoes to absorb the dressing and the caramelized onion flavor to fully develop. Just store it in the refrigerator and give it a gentle stir before serving.

What type of potatoes work best for this recipe?
Waxy potatoes like baby potatoes, Yukon Gold, or red potatoes are the best choice because they hold their shape after cooking. Avoid starchy potatoes like russets, which can fall apart and become mushy when mixed.

How do I properly caramelize onions without burning them?
The key is cooking them slowly over medium-low heat. Stir occasionally and be patient—this process takes about 15–20 minutes. If they start to stick, you can add a small splash of water to help them soften without burning.

Can I serve this potato salad warm?
Yes, this salad is delicious both warm and cold. Serving it warm enhances the richness of the caramelized onions and bacon, while chilling it gives it a more classic potato salad texture and flavor.

How long does this potato salad last in the fridge?
It can be stored in an airtight container in the refrigerator for up to 3–4 days. For the best texture and flavor, give it a quick stir before serving and add a little fresh garnish if needed.
