Short rib tacos

Ingredients needed

I flavored the beef with onion, garlic, taco seasoning and fresh jalapeños but you could add a one or two chipotles with a few tablespoons of adobo sauce for extra smokiness if you preferred. Dried chillies/chiles like guajillo or ancho chiles will also work well.

  • Beef short ribs. 
  • Onion.
  • Fresh garlic cloves.
  • Taco seasoning. I make my own taco seasoning but you can use any store-bought spice mix containing cumin, smoked paprika, oregano, etc.
  • Salt and black pepper. 
  • Fresh jalapeño. 
  • Beef stock/beef broth.

For the salsa roja

The salsa Rosa adds incredible flavor to the tacos but you can use any salsa/sauce of your choice on these tacos.

  • Ripe tomatoes. 
  • Red onion.
  • Jalapeño pepper.
  • Garlic cloves. 
  • Cilantro/coriander. 
  • Lime juice. 
  • Olive oil.
  • Salt.

For the tacos

  • Tortillas. I used corn tortillas but flour tortillas work just as well.
  • Pickled red onions.
  • Avocado slices.

Braised short ribs for tacos

How to make short rib tacos (Summary)

  1. Slow braise the short ribs: Pat the short ribs dry with paper towels then season generously with salt and black pepper. Preheat a large, deep braised or Dutch Oven over medium-high heat then add the ribs in batches, searing for a few minutes until brown on both sides. Add the remaining aromatics and spices then pour in the stock. Close with a lid then place in the oven and allow to braise for 3 hours or until the short ribs are fall-apart tender. Remove from the oven and allow to cool for 30 minutes before shredding the meat. Discard any excess fat and bones. The beef can be cooked in a slow cooker or Instant Pot until it shreds easily, too.
  2. Make the pickled onions: While the meat is braising, make the pickled onions according to recipe instructions.
  3. Make the salsa roja: Place all the ingredients for the salsa in a baking dish then place in the oven and allow to roast for 30-45 minutes until the tomatoes are soft and the skin is blistered and slightly charred. Remove from the oven, discard the jalapeño stems then transfer all the tomatoes, onions, etc to a blender or food processor and blend until smooth. Taste and adjust seasoning by adding more lime or salt.
  4. Assemble the tacos: Heat tortillas over an open flame or in a hot pan. Add a generous amount of short rib meat to each tortilla then top with avocado, a generous spoon of salsa roja and some pickled onions. Serve immediately.

Can I make this in advance?

The short ribs can be braised up to 4 days in advance and kept in an airtight container in the fridge of frozen for up to 3 months. The salsa can be made 2 weeks ahead and the pickled onions will last in the fridge for up to one month.

Instructions

Braise the beef

  • Pat the short ribs dry with paper towels then season generously with salt and black pepper.
  • Preheat a large, deep braised or Dutch Oven over medium-high heat then add the ribs in batches, searing for a few minutes until brown on both sides. Allowing the beef to develop a deep brown crust will add incredible depth of flavor to the finished braised beef.
  • Add the remaining aromatics and spices then pour in the stock.
  • Close with a lid then place in the oven and allow to braise for 3 hours or until the short ribs are fall-apart tender. (The beef can be cooked in a slow cooker or Instant Pot until it shreds easily, too.)
  • Remove from the oven and allow to cool for 30 minutes before shredding the meat. Discard any excess fat and bones.

For the pickled onions

For the salsa roja

  • Place the tomatoes, onions, jalapeño and garlic in a baking dish and drizzle with the olive oil and season with salt. Place in the oven and allow to roast for 30-45 minutes until the tomatoes are soft and the skin is blistered and slightly charred.
  • Remove from the oven, discard the jalapeño stems then transfer all the tomatoes, onions, etc to a blender or food processor with the coriander/cilantro and lime juice then blend until smooth.
  • Taste and adjust seasoning by adding more lime or salt.

Assemble the tacos

  • Heat tortillas over an open flame or in a hot pan.
