Super Bowl Week: Really Onion Dip

I know, you're thinking, an onion dip? That's rather boring. But there has to be an onion dip of some sort at a football party, and I think this one adds a little more zip than the typical bowl. As the title says, it's not just onion, it's really onion. Hot sauce adds more kick too.

As a bonus, this is from Food Network's Sara's Secrets. I really wish Sara Moulton was on still on the channel. (Update: I got an e-mail from someone who used to work with Sara who informs me that she has a new show premiering on PBS this April titled Sara's Secrets For Weeknight Meals - thanks for the tip Lesley!)

Really Onion Dip

3 medium onions, 2 unpeeled, 1 peeled
1 cup extra-virgin olive oil
2 cups mayonnaise
1/2 cup sour cream
1 tablespoon white wine vinegar
2 teaspoons kosher salt
2 scallions (white and green parts), minced
Freshly ground black pepper
Hot pepper sauce
Potato chips, for serving

Preheat oven to 425 degrees F.

Rub unpeeled onions with a bit of the olive oil; roast until soft, about 45 minutes. Cool and peel.

Finely dice the peeled raw onion. Heat a large skillet over medium-high heat; add remaining oil and heat until quite hot. Add diced onion and cook, stirring occasionally, until edges begin to brown, about 5 minutes. Turn to medium-low and cook until onion is golden brown, about 18 minutes. Scrape onion, oil, and juices into a sieve over a bowl. Drain onions and spread on a paper towel-lined plate. Cool the strained oil.

Puree roasted onions in a food processor. Add mayonnaise, sour cream, vinegar, and salt; pulse until smooth. With the motor running, drizzle in 1/4 cup of the flavored reserved oil. Transfer to a serving bowl. Stir in scallions, pepper, and hot sauce to taste. Refrigerate at least 3 hours. Scatter the fried onions over the top just before serving with potato chips.
