The Full French Onion Potato Salad Recipe
Ingredients
- 3 pounds red potatoes, cut into small cubes
- 2 large yellow onions, chopped into large chunks (about 1-inch pieces)
- 2 tablespoons extra virgin olive oil
- 2 teaspoons seasoned salt
- 2 teaspoons black pepper
- ½ cup sour cream
- ¼ cup mayonnaise
- ¼ teaspoon paprika
- ¼ teaspoon black pepper (to taste)
- Fresh chives, chopped (for garnish)
Instructions
- Preheat Oven: Start by preheating your oven to 425°F (220°C). Line a large sheet pan with parchment paper for easy cleanup.
- Prepare Vegetables: In a large bowl, toss the cubed red potatoes and chopped yellow onions with the olive oil, seasoned salt, and black pepper until they are evenly coated. This step ensures that every bite is flavorful!
- Roast: Spread the potato and onion mixture in a single layer on the prepared sheet pan. Roast in the oven for 60 to 75 minutes, flipping the vegetables halfway through, until they are golden brown and crispy on the edges. Keep an eye on them to prevent burning!
- Cool: Once roasted, let the potatoes and onions cool for about 15 minutes. This cooling step helps the flavors to meld.
- Make Dressing: While the vegetables are cooling, whisk together the sour cream, mayonnaise, paprika, and black pepper in a medium bowl until the mixture is smooth and creamy. Taste and adjust the seasoning if necessary.
- Combine: In a large bowl, gently fold the roasted potatoes and onions into the creamy dressing until everything is well coated. Be careful not to mash the potatoes!
