Roasted Onion and Bacon Dip

Makes about 1½ cups

3 medium yellow onions, unpeeled
½ tablespoon olive oil
6 slices bacon, cooked crisp and drained, crumbled
2/3 cup sour cream
1/3 cup mayonnaise
1 teaspoon Worcestershire sauce
1 teaspoon Dijon mustard
2 tablespoons scallions, chopped fine
½ teaspoon table salt
Ground black pepper

1. Adjust oven rack to lowest position and heat oven to 400 degrees. Line a baking sheet or with aluminum foil; rub foil with oil. Cut onions in half crosswise (along their equators). Cut an X, about 1-inch deep, in the root and stem ends. Place onions cut side down on baking sheet. Roast until dark brown around bottom edge, about 30 minutes. Transfer pan to rack; let onions rest for 5 minutes before peeling off the pan. Let onions cool, then peel and chop fine.

2. Mix all ingredients (including onions) in medium bowl. Serve immediately or chill.
