French Onion Dip Recipe
Introduction
French Onion Dip is a creamy, savory treat that’s perfect for any gathering or casual snack time. With rich caramelized onions blended into a smooth base of sour cream and mayonnaise, this dip pairs wonderfully with crispy potato chips.

Ingredients
- 3 tablespoons extra-virgin olive oil
- 2 large yellow onions, julienned
- Kosher salt and freshly ground black pepper, to taste
- 2 cups sour cream
- 2 tablespoons mayonnaise
- Chopped fresh chives, to garnish
- Potato chips, to serve
Instructions
- Step 1: In a large skillet, heat the olive oil over medium heat. Add the julienned onions and season with 1½ teaspoons of kosher salt. Cook, stirring frequently, until the onions begin to soften and reduce in size, about 8 to 10 minutes.
- Step 2: Reduce the heat to medium-low and continue cooking, stirring occasionally, until the onions are deeply caramelized and golden brown, about 25 to 30 minutes. If the onions start to burn or get too dark, add a few tablespoons of water to deglaze the pan, scraping up the browned bits. Set the caramelized onions aside to cool.
- Step 3: In a large bowl, combine the cooled caramelized onions with sour cream and mayonnaise. Stir well until all ingredients are evenly incorporated.
- Step 4: Transfer the dip to a serving dish and garnish with chopped fresh chives and freshly ground black pepper. Serve immediately with potato chips.
Tips & Variations
- For deeper flavor, use sweet onions or add a splash of Worcestershire sauce to the dip mixture.
- To make ahead, prepare the caramelized onions in advance and refrigerate; mix with sour cream and mayonnaise just before serving.
- Try adding a pinch of garlic powder or smoked paprika for a subtle twist.
Storage
Store leftover dip in an airtight container in the refrigerator for up to 3 days. Stir well before serving. This dip is best served chilled or at room temperature. Avoid freezing as the texture may change.

FAQs
Can I use regular onions instead of yellow onions?
Yes, though yellow onions are preferred for their natural sweetness. White or red onions can be used but may alter the flavor slightly.
How long can I caramelize the onions for the best flavor?
Cooking the onions low and slow for 25 to 30 minutes develops the richest, sweetest flavor without burning.

- Consider adding a splash of Worcestershire sauce or a pinch of smoked paprika for a slight twist.
- Use thinly sliced onions for more even caramelization.
- Adjust seasoning with salt and pepper to suit your taste.
