Sweet Potato And Pancetta Gratin - cooking recipe

Ingredients

1 large sweet potato
1 -2 tablespoon butter
1 cup cream or 1 cup half-and-half
salt and pepper
1/4 cup pancetta, cubed
1 small onion, cut in half and then each half cut into rings
sharp cheddar cheese, grated

Preparation

Grease 8 x 8 pan and preheat oven to 350 degrees.
Slice sweet potato into thin rounds, about 1/8 inch thick. Not paper thin, but evenly sliced. I use a mandoline.
Heat cream and butter in a saucepan until simmering. Add sweet potatoes, salt and pepper. Cook until just tender or until most of the liquid evaporates, about 10 minutes.
Cook pancetta in small, nonstick pan, until crispy. Remove, place on paper towel and caramelize onions in pancetta fat on low heat, around 10 minutes.
Layer sweet potatoes on bottom of baking dish, add pancetta and onions on top (or carefully stir them all together). Sprinkle top liberally with cheddar cheese.
Bake for 15 - 20 minutes uncovered until cheese bubbles.
