Preheat oven to 400°F. Slice the top off the head of garlic, exposing the cloves. Place the head of garlic on a sheet of aluminum foil and drizzle with 1 tsp olive oil, rubbing it around to make sure all the cloves are coated.

Wrap the aluminum foil around the garlic, place on a baking sheet, and bake until garlic is soft, golden, and easily squeezes out of its peel, about 40 minutes.

While the garlic is roasting, start caramelizing the onion. Heat 1 tbsp olive oil and 1 tbsp butter in a large skillet. Add the onion slices and cook over low heat until they reach a deep brown color and are very soft, about 45 minutes to an hour.

In a medium bowl, combine cream cheese, sour cream, mayo, 1/2 of each of the shredded cheeses, and thyme.

Fold in the caramelized onions and roasted garlic and pour the mixture into a baking dish. Increase oven temp to 425°F.

Sprinkle the remaining cheese on top of the dip and bake until bubbly and slightly browned on top, about 20 minutes. Serve with Stacy’s^® Simply Naked^® Pita Chips and enjoy!
