Special Siopao Asado Recipe

Why not make it a fun afternoon or a fun weekend than to make Siopao Asado (Filipino Steamed Buns With Pork Asado Filling)—a famous snack here in the Philippines? Nowadays, I find that making food that you usually eat outside something you can eat at home is really extra satisfying.

Continue to read this recipe article below to learn how to make the fluffiest and softest Siopao Asado. There are detailed explanations on how to make it better so be sure to read all of it!

What is Siopao Asado?

Siopao is a popular Filipino snack which is an adaptation of a Chinese steamed bun. This has become popular all over the Philippines through bakeries and vendors in Chinese restaurants and even in convenience stores.

There are a lot of varieties when it comes to the fillings of siopao, but for this recipe, we are going with the more popular one, the Siopao Asado. This consists of pork made with soy sauce, oyster sauce, sugar, and other common ingredients such as onion and garlic. 

How to Make the Siopao Asado Filling?

Making the filling is as easy as cooking a normal recipe. To start off with this, make sure that the pork is cut nicely into chunks, or another option would be to shred the meat. The recommended pork parts for the asado filling would be pork shoulder or pork butt, as this would render the most flavor for the asado. 

Boil the pork meat along with soy sauce and oyster sauce and cook until the pork is tender, which should take about 30 minutes. Once that’s done, stir in the diluted cornstarch along with sugar, and let it cook for 2 to 3 minutes while stirring continuously until the sauce thickens.

How to Assemble the Siopao Buns?

  • Place the dough on a flat surface and then form into a long log shape so you can cut it easier into equal sizes. Having a weighing scale at your disposal is better so you’re sure about the sizes. Especially if you plan on selling the siopao.
  • Once you form the dough into balls, this is optional but you can let it rise for another 30 minutes to 1 hour in order to have puffy siopao.
  • For arranging the buns with the asado filling, you need to flatten the dough balls using a rolling pin. One tip is to make the edges thinner, keeping the center thick so you have a nice base for the siopao.
  • With a tablespoon, scoop a portion of the asado filling and then place at the center of the flattened dough.
  • Wrap the edges onto the center, covering the filling and then ping the center and twist to secure the siopao.
  • Transfer the siopao pieces into a steamer. A good distance would be an inch apart from each other to allow space to cook evenly and nicely. Steam for about 15 to 20 minutes. Make sure that the steamer is set to low heat.
  • Do not immediately open the steamer lid after steaming, so that we are sure the siopao won’t deflate. Keep it there for 5 minutes or so.
