This burger takes the core flavors of Filipino sisig — soy sauce, calamansi, chili, garlic, and crispy pork — and packs them into a ground pork patty topped with calamansi mayo and chicharrón. It comes together in 45 minutes and the patties hold up well through the week, which makes it worth the slightly unusual ingredient list. If you can find calamansi, use it; if not, lime gets you close enough.
Before you start
The two things that actually determine how this burger turns out are fat ratio and patty temperature. Ground pork at 70/30 lean-to-fat stays juicy through a full cook to the required 160°F (71°C) internal — leaner pork dries out fast and there’s no recovering it once it’s in the pan. The second thing: chill your formed patties for at least 20 minutes before cooking. Cold fat holds the patty together when it hits a hot surface. Skip that rest and the patty loosens up, spreads unevenly, and loses the crust you want. Skip the egg in the mix — it makes the patty mushy. The soy sauce and breadcrumbs are enough to bind everything; the egg just adds moisture the patty doesn’t need.
Common problems and fixes
- Patties shrink into thick pucks: Press a shallow dimple into the center of each raw patty before cooking. Ground pork contracts from the edges inward; the dimple compensates and you get a flat, even burger instead of a dome.
- Calamansi mayo turns watery and slides off: Squeeze calamansi juice into the mayo and let it sit for 5 minutes, then stir again before spreading. Fresh citrus juice thins mayo on contact; a short rest lets it re-emulsify slightly and cling better to the bun.
- Chicharrón goes soft before you eat: Add it at the very last second — after the patty is on the bun and the mayo is spread. Any steam from a hot patty will turn crispy pork rinds into chewy ones within two minutes.
- Patty sticks to the pan and tears: Don’t move it early. Let it cook undisturbed for 3–4 minutes on the first side until it releases on its own. Pork patties with this fat ratio will let go of a hot pan when they’re ready; forcing them off early pulls the crust apart.
- Leftover patties dry out when reheated: Reheat in a covered skillet over low heat with a tablespoon of water in the pan. The steam keeps the pork from tightening up. Microwaving works but the texture suffers noticeably.
Filipino Sisig Pork Burger
Ingredients
Pork Patty
- 1 lb ground pork Preferably with a 70/30 lean-to-fat ratio for juiciness
- 2 tbsp soy sauce Filipino soy sauce for authentic taste
- 1 tbsp calamansi juice Freshly squeezed for tanginess; substitute with lime if unavailable
- 1 tsp garlic Minced finely
- 1 tsp red onion Finely chopped
- 1 tsp red chili Minced, adjust spice level to preference
- ½ tsp black pepper Coarsely ground for a bit of heat
- 1 large egg For binding
- ¼ cup breadcrumbs To help hold the patty together
Calamansi Mayo
- ½ cup mayonnaise Preferably Japanese mayo for richness
- 1 tbsp calamansi juice For a zesty kick
- ½ tsp garlic powder For additional depth of flavor
Toppings & Assembly
- 4 large brioche buns Lightly toasted for texture
- ½ cup chicharrón Crushed for crunch
- ½ cup green onions Thinly sliced for freshness
Instructions
Make the Pork Patty
- In a mixing bowl, combine ground pork, soy sauce, calamansi juice, minced garlic, chopped red onion, minced chili, black pepper, egg, and breadcrumbs. Mix well until evenly combined.
- Form the mixture into four equal patties, about ¾ inch thick. Let them rest while preparing the sauce.
Prepare the Calamansi Mayo
- In a small bowl, whisk together mayonnaise, calamansi juice, and garlic powder. Set aside.
Cook the Patties
- Heat a nonstick pan or grill over medium-high heat. Cook the patties for 4-5 minutes per side, or until internal temperature reaches 160°F (71°C). Let rest for 5 minutes.
Assemble the Burger
- Toast the brioche buns lightly. Spread a generous amount of calamansi mayo on the bottom bun, place the cooked pork patty, sprinkle crushed chicharrón, and garnish with sliced green onions. Top with the other half of the bun.
Notes
- For extra flavor, grill the patties over charcoal to introduce a smoky element.
- If calamansi is unavailable, Meyer lemons or limes can be good substitutes.

Frequently asked questions
Can I mix and shape the patties the night before?
Yes — this is one of the better burgers for overnight prep. Shape the patties, layer them between parchment, cover tightly, and refrigerate for up to 24 hours. The soy sauce and calamansi actually penetrate the meat more evenly with a longer rest, so the flavor is slightly better the next day.
What’s the best substitute if I can’t find calamansi?
Fresh lime juice is the most practical swap — use the same quantity called for in the recipe. Meyer lemon works too and is a bit closer in sweetness, but regular lemon is sharper and can overpower the soy sauce, so use about 20% less if that’s all you have.
Can I freeze the cooked patties?
Yes, cooked pork patties freeze well for up to 2 months. Cool them completely, wrap individually in plastic wrap, then bag them. Reheat from frozen in a covered skillet over medium-low heat until the center hits 160°F again — about 8–10 minutes.
How do I know the patty is fully cooked without cutting into it?
Use an instant-read thermometer and check the center — ground pork must reach 160°F (71°C). Color alone is not reliable; pork can look done on the outside while the center is still underdone, especially with thicker patties.
