Homemade Plateada Avocado Mayo Sandwich Recipe
Preparation: 30 minutes
Cooking: 60 minutes
Servings: 4
Ingredients
Braised plateada
- 1½ kg (3⅓ lb) of plateada (beef rib cap)
- 300 ml (1¼ cups) of red wine
- 60 ml (¼ cup) of olive oil
- 4 celery stalks, chopped
- 2 tomatoes, diced
- 1 medium onion
- 1 garlic clove, chopped
- ½ red bell pepper, chopped
- 1 tablespoon of ají de color (Chilean paprika)
- 1 teaspoon of oregano
- Fine salt
- Black pepper
To assemble
- 4 marraquetas (Chilean bread rolls)
- 2 large avocados
- ½ lemon
- Mayonnaise
Instructions
- Lightly trim the fat from the plateada and cut it into four equal pieces. Place them in the pressure cooker with the olive oil, heat over medium heat, and sear the meat evenly without browning it too much.

- Add the quartered onion, tomato, garlic, bell pepper, and celery, season with salt and pepper, and add the oregano and ají de color. Pour in the wine and top up with water until everything is covered. Stir gently, close the cooker, and cook over medium low heat for 50 minutes from when it starts to whistle. Turn off and let rest 10 minutes before releasing the pressure.

- Move the meat to a cutting board and slice it, ideally thin. Keep it warm in its juices. Peel the avocados and mash them with a fork without turning them into a paste, then add a few drops of lemon and a pinch of salt.

- Split the marraquetas and toast them until lightly crisp. Cover the base with the juicy plateada, add a generous layer of mashed avocado and mayonnaise to taste, and close with the top of the bread. Serve the plateada sandwich right away, with a glass of wine, a good coffee, or a beer.
Additional Tips
Do not over trim
Leave some fat on the meat, as it concentrates flavor during cooking. When searing, only seal in the juices without browning too much.
Serve the broth
Save the cooking broth and serve it hot in small cups alongside the sandwich.
Keep the meat juicy
Keep the sliced meat in its juices while you toast the bread and assemble the sandwiches so it stays warm and moist.
