Preheat oven to 375 degrees.

Spray an oven proof pan.

Wash or peel the potatoes.

Melt butter and mix with olive oil.

Dip each potato in the butter/oil mix. Ensure each potato is fully coated. Position potatoes in the pan in a single layer leaving some space between them. Reserve the remaining butter/oil mix.

Roast potatoes checking for doneness after 30-40 minutes. When potatoes are fork tender remove from the oven.

Rewarm the remaining butter/oil mix and pour over the potatoes. Sprinkle with sea salt and parsley just before serving.
