These creamy mashed potatoes get their flavor burst from garlic and caramelized onions. They're great with any meal. This came from Country magazine. I have not tried this, just posting for easy finding.
Remove papery outer skin from garlic (do not peel or separate cloves). Cut off top of garlic bulb. Brush with 1 teaspoon oil. Wrap bulb in heavy-duty foil. Bake at 425 for 30-35 minutes or until softened.
Meanwhile in a large skillet over low heat, cook onion in remaining oil for 15-20 minutes or until golden brown, stirring occasionally. Transfer to a food processor. Cover and process until blended; set aside.
Place potatoes in a large saucepan and cover with water. Bring to a boil. Reduce heat; cover and cook for 15-20 minutes or until tender. Drain. Place potatoes in a large bowl. Squeeze softened garlic into bowl; add butter, sour cream, cheese, milk, salt, pepper and onion. Beat until mashed.
