Guinness Baked Cheese Dip is a terrific appetizer, with 3 cheeses, caramelized onions, and Guinness beer! Served hot, you're gonna love it!
Melt butter on medium-low heat in a 8" cast iron skillet (or two 4"), OR an oven safe skillet. Add onions and salt; toss to coat onions with butter. Cook onions slowly on medium-low, stirring often until soft in texture and fully browned (20-25 minutes). Remove skillet from heat; let onions cool completely.
While onions cool, preheat oven to 400°F. AND prepare dip. Place cream cheese, mayonnaise, HALF the Dubliner cheese and HALF the Parmesan cheese in a medium bowl. Stir well, to combine. Once onions are cooled to room temp, stir them into the dip. Add Guinness beer and stir well, to combine.
Evenly spread dip mixture into an oven-safe baking dish, 8" cast iron (or oven-safe) skillet OR two 4" skillets. Sprinkle top with reserved Dubliner/Parmesan cheeses.
Bake at 400° F. NOTE: If using 8" skillet, bake for 25-28 minutes. Bake two 4" skillets for approx. 13-15 minutes. When done, the dip should be browned on top and cheese will be bubbly. Transfer hot skillet(s) to a wire rack; let dip cool 10-12 minutes before serving with crackers, pita chips or toasted baguette slices!
