Lemon zest, fresh oregano, and red-pepper flakes infuse the block of feta in this baked dip with tons of flavor.
Preheat oven to 350 degrees. Place feta in middle of a 9-inch pie dish. Pour oil over cheese; sprinkle remaining ingredients on and around it. Cover with parchment-lined foil and bake until heated through, about 40 minutes. Let cool slightly before serving with crackers or crostini.
