Preparation

Get these tasks done before you start cooking.

Prepping the Potatoes

1
Preheat the Oven
Preheat oven to 400°F (200°C).
2
Slice the potatoes
Slice the potatoes thinly, maintaining an intact base.
Tip: Use a mandoline for uniformly thin potato slices.
3
Season and Oil Potatoes
Brush potatoes with olive oil and season with salt and pepper.

Caramelizing the Shallots

1
Melt the Butter
In a skillet, melt butter over medium heat.
2
Cook Shallots
Add shallots and cook until translucent.
3
Caramelize
Stir in sugar and balsamic vinegar, cooking until caramelized.
Tip: Be careful not to burn the shallots, as they quickly go from caramelized to charred.
