Filipino sour soup made with leftover lechon, tamarind broth, and vegetables. A tangy, hearty way to enjoy roast pork again. The comforting sourness of sinigang meets the smoky richness of lechon. A leftover makeover that turns yesterday’s feast into today’s soul food.
I guess you’ll see several lechon-related posts here in the coming weeks, we just hosted a party, and like any Filipino host, we ended up with more spit roast pork than we could finish in one sitting. As you’d expect, the first thing to disappear was the golden, crispy skin with that thin, juicy layer of meat underneath. What’s left behind? The appendages, the bones, the ribs, and the head, all still rich with flavour and meat clinging to the bone.
Now, as delicious as lechon is, no one wants to eat it plain day after day. That’s why most Filipino households transform the leftovers into something new, most often Lechon Paksiw, simmering chunks of roast pork in a sweet, tangy, and savoury sauce made with vinegar, sugar, and lechon sauce. Comforting, yes, but even that can feel heavy if repeated too often.
So, I decided to mix things up. I took those leftover ribs and backbones and turned them into Sinigang na Lechon, a bold twist on the classic Filipino sour soup. Imagine the depth of smoky, roasted lechon mingling with the tangy comfort of tamarind broth, rounded out by vegetables that soak up every bit of flavour. The richness of the pork meets the sharpness of sour soup, and the result is a perfectly balanced bowl of comfort. And if you don’t fancy this recipe today, we’ve already shared a roundup of delicious lechon ideas, from Lechon Fried Rice to Lechon Taquitos, that might just inspire your next leftover makeover.
The Story Behind Sinigang
Sinigang is one of the Philippines’ most beloved soups, defined by its sour tamarind-based broth and loaded with vegetables like kangkong, okra, and taro. It’s hearty yet refreshing, perfect on rainy days or when you simply crave something warming and satisfying. Traditionally, pork belly, beef short ribs, fish or shrimp take centre stage.
But Filipino cooking has always been about resourcefulness, transforming what you have into something delicious. Using leftover lechon in sinigang is a natural extension of that philosophy. It keeps the spirit of the dish alive while giving it new depth: the smoky, roasted notes of the lechon enrich the broth in ways raw pork never could. It’s proof that leftovers can sometimes create something even better than the original.
Tips for the Best Sinigang na Lechon
Choose the right cuts – Ribs, backbone, and other meaty bones are ideal. They’ll add body to the broth.
Balance the fat – Lechon is naturally rich, so the sour tamarind broth is essential to cut through the fattiness.
Don’t skip the taro – This root vegetable not only thickens the soup slightly but also soaks up that tangy flavour.
Fresh tamarind beats mix – If you can find fresh tamarind pulp, it adds a brighter, more natural sourness compared to powdered mixes.
This Sinigang na Lechon is proof that leftovers don’t have to feel repetitive. In fact, with a little creativity, yesterday’s feast can transform into something completely new, comforting, vibrant, and full of soul.
Since when taro is a vegetable :-)) They look floury and literally melt in mouth..those kind of taros are the best. Love lechon and I would never worry about the leftover…the more, the merrier!

Yeah the small Japanese taro are the best, very creamy.
I love the savory-sour combination, Raymund.
A great idea to use up leftovers, Raymund! I like to do that with a chicken carcass!
