That is awesome, great side dish for sure. Putting that one on the list to do. May cut in half for the two of us.

Yes it does make a lot. Using the leftovers for kielbasa cabbage stew.
I used three huge sweet onions. The mandolin slicer made quick work on thinly slicing.
I subbed good smoked paprika instead of cayenne. ( hate the stuff, all heat no flavor )
I didn't have gouda, just mild cheddar and Colby jack.
I think pepper jack would be a good sub also.
 
This sounds like a winner! Just an observation.....one of the links in your post leads to the recipe in Southern Living. Under Tips for Making Tennessee Onions, they call for slicing the onions 1/2-inch thick (the ingredient list does call for 1/4-inch). It's probably a typo but a thicker cut could lead to a heartier mouthfeel, whereas the 1/4-inch cut would be more delicate and would probably blend in better with the cheese.
 
Hi Rita, nice to hear from you!
I did see that.
I used the thin insert on my Borner V slicer.
Checking the manual it does 3.5 mm which is roughly 1/8".
Next time I'll try the thick insert which is closer to 1/4" , 7 mm
