Combine the artichoke hearts, mayo, garlic, Parmesan and Swiss cheese in a 2 ½ quart, oven-safe, baking dish.
Heat, uncovered for approximately 25 minutes in a 350 degree oven.
The dip should be bubbly and melted through.
Serve with tortilla chips.
Some variations you can make are:
You can add spinach (if you like that kind of thing).
You can add green chiles and swap out the parmesan for jack cheese.
You can add roasted red peppers to add even more flavor.
The addition of bacon wouldn't hurt anything.
Cream cheese would make this even more creamy and tangy which would be delish! It would also help to stretch the recipe if you are serving a lot of people. Grab 8 ounces and add it before you put this dish in the oven. Make sure to stir well.
