This delightful recipe for warmed Collard Greens has been adapted from a Bon Appetit magazine recipe for Slow Cooked Collard Greens in Olive Oil. Enjoy!
Heat ½ cup oil in a large saucepan over medium heat. Cook garlic and red pepper flakes, stirring often, until garlic is golden, about 4 minutes.
Add collard greens to saucepan a handful at a time, stirring until each addition is wilted before adding the next.
Season with salt and add 1 cup water. Bring to a simmer, then reduce heat so mixture is at a very gentle simmer. Cover and cook, occasionally removing lid to stir, until greens are tender and very dark green, 1-1-½ hours.
Let cool slightly, then stir vinegar and sugar into the greens.
Transfer to a serving bowl and drizzle with more oil and a splash more of vinegar if desired.
