This cheesy dip is made with just 4 ingredients--Swiss cheese, sparkling wine, cream cheese, and mustard. It's perfect for dipping and dunking bread and crackers and is ideal for sharing with friends.
Combine the wine, cream cheese, Swiss cheese, and mustard in a cast-iron skillet.
Set it over low heat on your stovetop, grill, campfire, or camp stove and let it melt, stirring occasionally, until smooth, 10 to 15 minutes.PRO TIP: When you combine all of the ingredients, the skillet will be very full. To make it easier to stir, add half of the Swiss cheese at first, then add the remaining half once everything is melted.
Serve immediately, with bread cubes for dipping.
Notes
Scaling--This cast iron skillet cheese dip recipe was created for a small 6-inch skillet, which is perfect for feeding 4 to 5 people. To make a big batch, double the amounts and prepare it in a 10-inch skillet.
Keep it on low heat--Melt the cheese over low heat. I can't stress the importance of this enough. Don't try to rush it. Letting the mixture get too hot can cause the cheese to separate and become grainy.
Storage and reheating--Store leftover cheese in a sealed container in your fridge or cooler for up to 3 days. Reheat in a skillet over low heat, or in 15-second bursts in your microwave until warmed through.
Dietary--This recipe is suitable for gluten-free diets.
