In an 8x8 inch pan, combine minced garlic and salt. Use the back of a spoon to smash the salt into the garlic, forming a paste. Add lemon juice, olive oil, black pepper, oregano, and water. Stir to combine.
Add potato wedges and toss to coat.
Bake 60 minutes, stirring every 20 minutes, or until water has evaporated and potatoes are tender.
