- Peel potatoes and measure all ingredients for marinade.  Preheat oven to 375 degrees F. 
- Cut each potato into eighths and try to keep the potato pieces as uniformly cut as possible so that they cook evenly. 
- In a bowl, use a whisk to combine, extra virgin olive oil, lemon juice, 2 teaspoons of Greek oregano, 4 large garlic cloves, finely minced, 1 tsp salt and 1/2 teaspoon freshly ground black pepper. 
- Spread the cut up potatoes out evenly in a baking dish and pour the marinade over the potatoes to coat them well. 
- Cover potatoes with aluminum foil and seal edges tightly.  Place in preheated oven for 50 minutes.     
- After, 50 minutes, remove the aluminum foil, baste the potatoes and cook for an additional 30 minutes. For the final 5-7 minutes, baste once more and turn the broiler on so that the potatoes get crispy on top. 
- Serve immediately.
