Caramelize for about 40 minutes, stir often and deglaze with 2 tbsp water as needed. Add the salt, nutmeg, thyme, and balsamic vinegar, then continue cooking for another 20 to 30 minutes until deeply golden.

Build the Onion Gravy: Push the onions to one side of the skillet. Add the butter to the empty side and let it melt. Sprinkle in the flour and stir into the butter for about 3 minutes. Gradually stir in 2 cups of beef broth, adding as much of the remaining broth as needed till you reach a thickened consistency. Remove from heat.

Prepare the Potatoes: Using a sharp knife, cut each potato in a hasselback style. See notes for optional help on how to do this. In a small bowl, mix the olive oil, garlic powder, onion powder, white pepper, and a pinch of salt. Brush the mixture generously over and between the slices of the potatoes.
