Another great recipe from "Cook's Illustrated" magazine. Be prepared for a STRONG lemon and garlic flavor!! These are the best potatoes that I have ever had!
Heat vegetable oil and butter in heavy-bottomed 12-inch nonstick skillet over medium-high heat until butter melts and foamind subsides, swirling pan occasionally. Add potatoes in a single layer (do not crowd pan); cook until golden brown (pan should sizzle but not smoke), about 6 minutes. Using tongs, turn potatoes over so second cut sides are down; cook until deep golden brown on second side, about 5 minutes longer. Reduce heat to medium-low, cover tightly, and cook until potatoes are tender when pierced with tip of paring knife, about 5 minutes.
While potatoes cook, combine garlic, olive oil, lemon juice and zest, and oregano in small bowl. When potatoes are tender, add garlic-lemon mixture, salt, and pepper; stir carefully (so as not to break potato wedges) to distribute. Cook, uncovered, until seasoning mixture is heated through and fragrant, 1 to 2 minutes. Sprinkle potatoes with parsley, stir gently to distribute; serve immediately.
