I love adding roasted garlic to my steakhouse mashed potatoes, as it creates mouthwatering roasted garlic mashed potatoes! Just throw one or two heads of garlic into the oven to roast (depending on how garlicky you want the roasted garlic mashed potatoes). When roasted, mash the garlic and potatoes together. You could also add bacon, cheese, green onions, or anything else that would pair well with potatoes! So get creative and make your own delicious twist on this recipe.
