Roasted Garlic and Caramelized Onion Dip
1 head of garlic
1 Tbsp butter
3 cups chopped onion (about 2 medium onions)
3 Tbsp sour cream
2 Tbsp cream cheese
3 Tbsp mayonnaise
1/4 tsp Worcestershire sauce
1/4 tsp cayenne pepper
Salt and pepper, to taste
Preheat the oven to 350. Cut the top off the head of garlic, place in a baking dish, and drizzle with olive oil. Bake for an hour. Squeeze the garlic from the cloves, mash with a fork, and set aside.
Meanwhile, heat a large skillet over medium-low heat and add the butter. After it melts, add the onions and some salt and cook slowly for about 20 minutes, covered, stirring occasionally. Unocver and turn the heat up to medium high. Cook the onions until golden brown, stirring quite frequently. Remove from heat and cool.
Combine the sour cream and cream cheese, stirring well. Add the mayonnaise, Worcestershire sauce, and cayenne. Mix to combine, then add the garlic and onions. Stir, then cover and refrigerate for a few hours or overnight. Taste and adjust seasoning with salt and pepper.
