Ingredients
- 2 tablespoons olive oil
- 2 sweet onions, thinly sliced
- 1 smoked ham hock (see Cook’s Note)
- 4 quarts unsalted chicken broth
- 2 dried chiles de árbol or 1 1/2 teaspoons crushed red pepper flakes
- 1 tablespoon chicken bouillon paste
- 6 pounds collard greens, rinsed, leaves stripped from stems
- 2 tablespoons white vinegar
Directions
- In a large pot, heat the olive oil over medium heat. Add the onions and ham hock. Cook, stirring occasionally, until the ham hock has a little golden-brown color and the onions start to turn translucent, 4 to 6 minutes. Add the broth, chiles, and bouillon paste. Bring to a boil, adjust the heat, and simmer until the stock is reduced and the meat is tender, 1 1/2 to 2 hours.
- Roughly chop the collard leaves into smaller pieces. Add the greens to the pot, submerging them in the porky stock.  Add the vinegar and stir. Simmer over medium-high heat, uncovered, until the leaves are tender, 18 to 25 minutes. Serve the greens with the porky stock.
