Potato Crusted Tilapia

Potato Crusted Tilapia:
4 tilapia filets (any thin white fish will work)
1 tbs fresh rosemary, chopped fine
1 large baking potato
salt, pepper

olive oil

1/2 tablespoon butter

Sprinkle fish with salt and pepper.

Very thinly slice potato, best to use a mandolin.

Lay 1 layer of potatoes on fish, overlapping like shingles. Sprinkle with salt, pepper, and rosemary

Drizzle a oven safe pan with olive oil and add butter, on med-high heat.

Preheat oven to 400 degrees.

Once butter is melted and starts to foam, add fish potato side down. Cook until potatoes brown around the edges about 5-7 minutes.

Put pan into the oven for 15 minutes until fish in cooked through. Remove from oven.

Carefully removed fish and potatoes with a spatula, should come out easily. 
I like to finish with a light sprinkle of salt.
