But first of all, let's answer the main question.

What is lechon sauce?

Lechon sauce is any dipping sauce paired with lechon pork or crispy pata. It uses common condiments like fish sauce, tomato ketchup, or the sweeter version-banana ketchup.

Sarsa is the traditional accompaniment to lechon or fried-food dishes. Made of a combination of mashed liver, vinegar, breadcrumbs, seasonings and other ingredients like garlic onions and sugar; it's then simmered until smooth paste form.

A Sarsa that has made waves since the late 1980s is Mang Tomas, a dip that Hernan Reyes created after he purchased a lechon shop in Quiapo Manila. The product was so popular that NutriAsia acquired it and rebranded it as “Mang Tomas All-around Sarsa” to demonstrate its versatility.

Another popular choice of a spicy condiment option for the dish would be the soy-based sauce, commonly called ‘sawsawan’.

Sawsawan means ‘dipping sauce' and is usually a simple vinegar dip with chillies (sukang may sili) or a soy sauce-based dipping sauce often called ‘Filipino Garlic vinegar sauce’ or ‘Soy and Vinegar dipping sauce’. Made with dark soy sauce, a dash or more of vinegar, sprinkle of brown sugar, aromatics like garlic and onion, adding some spice with ‘siling labuyo’ the spicier Filipino version of the bird’s eye chili, and the ‘siling mahaba’, the long green sweet chili.

Both are good at tempering the oiliness of fried or grilled food by adding salt, savory flavor, umami, or sweet and spicy notes.


The ingredients list

For the sarsa:

  • Chicken liver – the base of the sauce. You can also use pork liver.
  • Salt and black pepper – to elevate the flavors.
  • Cooking oil – for sauteing.
  • Onion and garlic – added for aroma and flavor.
  • White vinegar – removes unpleasant strong odors and tastes.
  • Water – to keep the sauce from being too thick.
  • Brown sugar – adds sweetness, lessens the acidity and saltiness.
  • Breadcrumbs – as a thickener, you can also use crushed or toasted then crushed bread.
  • Dark soy sauce – for color and umami flavor.

For the soy-based sauce:

  • Raw red onion and garlic – adds a sharp taste, cuts though the oiliness of the pork or choice of meat.
  • Red or green chili – creates a nice contrast of color and spice.
  • White vinegar or apple cider vinegar – for slight acidity and tang.
  • Dark soy sauce – Adds color, saltiness, and umami taste profiles.
  • Brown sugar – sweetness to temper the saltiness, spice, and acidity.


  • Use fresh ingredients for the best flavor.
  • This recipe can be made gluten-free by using gluten-free breadcrumbs or bread. Make sure to check if the soy sauce contains gluten, as many do. If not, you can use liquid aminos as an alternative. Check the ingredients list on store-bought sarsa.
  • Start with a base sauce recipe, and feel free to tweak it to your liking
  • It’s recommended to use the sauce once it’s cooled down, or the day after. Just to help all the flavors meld together.
  • To store the sauces, make sure too cool to room temperature before placing in an airtight container, in the fridge where they can last 2 months or more. However, if mold appears, discard the sauce.

Alternative dips

While you can make a sauce more suited to your taste at home, you can also find pre-made dipping sauces. Popular brands include:

  • Mang Tomas Sarsa is the lechon sauce and a very popular condiment. Made of ground liver, seasonings, and traditional aromatics.
  • Suka Pinakurat is an organic fermented coconut vinegar sauce, rich in chillies and aromatics. This spicy vinegar is great for grilling and frying seafood.
  • Sweet and Sour Chili Sauce – not the most popular choice but still beloved by many, especially fans of crispy pata. Although more commonly associated with fried lumpia, this sauce is suitable for those that prefer something sweet and with a little less salt.
  • While not as closely associated with lechon or crispy pata, chili garlic sauce has been making waves among people who enjoy spicy food. You can even mix it with sarsa or soy sauce dipping sauce.
