About

Lomo Mechado is a Mexican recipe that consists of roasted pork sirloin stuffed with spices, nuts, prunes, and bacon. It is usually served for special occasions like weddings, birthdays, or for Christmas Eve dinner.

The recipe originated in Andalusia, Spain, and then spread to many Latin American countries, including Mexico, where to this day is one of the most traditional and popular dishes for Christmas and New Year’s Eve.

Mechado comes from the Spanish verb “mechar” which is a cooking technique that consists of introducing pieces of some food or seasoning into a piece of meat that is going to be cooked.

An incision is made with a knife in the meat and it is filled with various ingredients like olives, capers, spices, vegetables, dried fruits, and cold meats, among others.

There are many versions of Lomo de Cerdo Mechado in Mexico, the difference among those are in the ingredients for stuffing the pork meat and in the sauce to serve it.

The idea is that when the meat is sliced the layered elements can be seen, in addition to giving flavor.

This final dish looks beautiful yet it’s quite easy to make. It is perfect to impress your guests and family at a holiday dinner.

So keep reading because I’ll give you the step-by-step recipe with photos + the quick printable recipe at the end of the post.

Ingredients

  • Pork Sirloin (lomo): You will need a large piece of about 2.2 pounds / 1k which is enough to feed 4 people.
  • Bacon: For flavor, you’ll first cook it and then use it for stuffing.
  • Prunes: You will need pitted prunes for the stuffing and some more for the sauce.
  • Chilies: Chipotle peppers add a flavorful smoky touch, you can leave them out if you don’t want the sauce to be slightly spicy or add less than the recipe calls.
  • Walnuts: You can use walnuts or pecans, or any other type of nut you prefer.
  • Butter: Unsalted butter to make the sauce.
  • Oil: Use any type of oil you prefer to sear the meat.
  • Onions: Yellow, white, or red, finely chopped.
  • Orange: Use fresh orange juice.
  • Jugo Maggi: Look for this sauce at your local supermarket near as Maggi seasoning or Maggi sauce. Or substitute with 1:1 parts of Worcestershire sauce and soy sauce.
  • Spices: Cinnamon, whole cloves, salt, and pepper.

How to Make

Slightly fry the bacon on its own fat, it doesn’t need to be crispy just a bit browned. Set aside until it reaches room temperature.

Place pork loin on a cutting table. With a long and narrow knife, make various longwise incisions in the meat.

Now, stuff the incisions with prunes, bacon, and walnut bites. Use one of your fingers to push the ingredients, making sure they are layered one after the other.

Tie the roast

  • Tie your loin roast by first making a slip knot on one end of the roast.
  • Then pull a length of twine out away from your anchor and create a large, loose loop.
  • Slide the loop over the roast and pull it tight.
  • Repeat the loops to the length until all roast is looped.
  • Pull the twine to secure the roast trying to keep an even shape.
  • Flip the roast, run the twine lengthwise, and tie it to the first knot you made.

Make the prune sauce

  • In a medium saucepan heat the butter over medium heat.
  • Add diced onion and cook until softened and translucent (about 4 minutes).
  • Add the prunes and then pour 2 cups of water. Bring to a simmer.
  • Add piloncillo, ground cinnamon, whole cloves, salt, and pepper. Mix to combine and simmer for 6-8 minutes. Remove from heat and allow to cool down.
  • Place the prunes mixture in a blender along with chipotle peppers, orange juice, and Jugo Maggi.

Roast

Roast in the preheated oven at 360°F (180°C) for 40 minutes.

Uncover and keep roasting for 10-15 more minutes or until the intern meat temperature reaches about 170°F (70°C).

Recipe Notes

  • Allow Lomo Mechado to rest so the juices will redistribute themselves all throughout the meat and not in your cutting board.
  • Make sure you remove the roasted lomo from the pan so it won’t continue cooking in the hot pan.
  • Invest in a meat thermometer, there are some really cheap ones in the market like this Instant read thermometer, those last forever!

How To Serve

You can serve Lomo Mechado sliced and drizzled with the scrumptious prune sauce, then pair it with your favorite sides. Here are my favorite classic side dishes I’d serve on a Mexican holiday table:

How To Store & Reheat

You can store lomo mechado leftovers in the refrigerator for up to 3 days in an airtight container or up to 2 months in the freezer.

Label the container before freezing. Use a permanent marker to note the type of meat, date, and any other useful information.

To reheat, arrange the roast in a baking dish and thin the prune’s sauce with a dash of water. Brush the roast with a bit of sauce and cover it with foil.

Reheat at 325°F (160°C) until heated through (from 15 to 20 minutes).

    Hi Mari,

    This looks and sounds gorgeous. I have cooked a similar recipe from Poland, no chillies in that one though! I wasn’t a fan of fruit with meat until I tried it and it just so happened that the fruit was Prunes.
    This is definitely one for Christmas week.

    Because of you I bought a Meat Thermometer! Life-changing, now I don’t have to worry about it being uncooked. My Lomo Mechado cooked perfectly, I served it in a party and they all loved it!
