This Filipino tofu sisig is crispy fried tofu tossed in a tangy, savory sauce of calamansi, oyster sauce, and mayonnaise - a plant-based version of one of the most popular Filipino pulutan dishes.
The original sisig is made from pork, but the tofu version has become a staple in its own right, popularized by Max's Restaurant in the Philippines and now made in Filipino homes everywhere.
The technique that makes or breaks it: press the tofu properly before frying, season it immediately after it comes out of the oil, and add the mayonnaise off the heat so it stays creamy rather than breaking. Thirty minutes, one pan, sizzling plate optional but recommended.

What Is Sisig?
Sisig comes from the Kapampangan word meaning "to snack on something sour" — originally referring to eating unripe fruit with vinegar or calamansi. The dish was born in Pampanga, the culinary heartland of the Philippines, where the traditional version was made from pig's head parts — ears, snout, and cheeks — grilled over charcoal, finely chopped, and mixed with calamansi, chilies, and onion. Bold, punchy, and intensely flavored, it became the definitive Filipino pulutan — food eaten alongside drinks, the way Filipinos do bar food.
From there, sisig evolved. Pork belly, chicken, bangus, and tofu versions all emerged as it moved from bars to restaurants to home kitchens. Max's Restaurant popularized the sizzling tofu version, giving it mainstream recognition as a legitimate vegetarian dish — creamy, spicy, and arriving at the table on a cast iron plate still sputtering. This recipe is inspired by that version.
What Is Tokwa?
Tokwa is the Filipino word for tofu, derived from the Hokkien Chinese. In Filipino cooking, tokwa typically refers to firm or extra-firm tofu - the kind used for frying and stir-frying rather than the soft silken tofu used in desserts like taho. For tofu sisig, extra-firm tokwa is what you want: it holds its shape through pressing, frying, and tossing in the sauce.
Ingredients
- Extra-firm tofu - Extra-firm only. Firm tofu has too much moisture and won't get properly crispy even after pressing. The extra-firm variety has lower water content from the start and produces a significantly better result. Two blocks feeds 4-6 people generously as a main dish with rice.
- Butter: Used to sauté the aromatics. Butter adds richness that oil alone doesn't, which is part of what makes sisig taste distinctly indulgent even in the tofu version.
- Garlic: Minced garlic brings a fragrant depth to the stir-fry.
- Onion: Red onions add a slightly sweet and sharp flavor base.
- Red and Green Bell Peppers: Add a pop of color and a touch of sweetness.
- Calamansi juice (or lemon juice): The sour element that defines sisig. Calamansi is the traditional choice - a small Filipino citrus fruit with a flavor that's sweeter and less sharp than lemon. Find it fresh or bottled at Filipino and Asian grocery stores. Lemon juice is the practical substitute and works well.
- Oyster Sauce: Adds savory depth and a slight sweetness that rounds out the acidity
- Kewpie mayonnaise: The finishing element that makes tofu sisig creamy and distinctly Filipino in character. Kewpie is Japanese mayo made with egg yolks only and rice vinegar - richer and slightly tangier than American mayo, and what most Filipino recipes use. Add it last, off the heat or with the heat turned very low.
- Maggi Seasoning or soy sauce: Enhances the dish with a salty, savory flavor. Use soy sauce as a substitute.
- Thai Chili Pepper: For a spicy kick; adjust the amount to your spice tolerance.
- Cornstarch: For coating the tofu before frying. Cornstarch (not flour) produces a thinner, crispier crust that holds up better in the sauce than a flour coating.
- Cooking Oil: Use Canola oil or avocado oil for deep frying.
Substitutions and Additions
- Tofu: Swap for tempeh or mushrooms for another plant-based option.
- Calamansi: Use lime juice if you don’t have calamansi on hand.
- Oyster Sauce: Replace with vegan oyster sauce or hoisin for a plant-based version.
- Maggi Seasoning: Substitute with soy sauce or skip it.
- Mayonnaise: Greek yogurt or vegan mayo works as a healthier or dairy-free alternative.
- Thai Chili Pepper: Substitute with cayenne or chili flakes for a milder heat.
- Butter: Use olive oil or vegan butter for a plant-based version.
The Tofu Prep: What Actually Makes It Crispy
Crispy tofu is all about removing moisture. Tofu is mostly water, and water in the pan creates steam, which prevents browning.
- Press it — wrap in paper towels, weigh it down for 15–20 minutes. This is the step most people skip and it makes the biggest difference.
- Pat dry again right before coating.
- Use cornstarch, not flour — lighter, crispier shell that holds up better in the sauce.
- Freeze for a meatier texture (optional) — freezing and thawing creates a chewier, more porous tofu that absorbs sauce more deeply.
- Season straight out of the oil — salt adheres best when the tofu is still hot.
How to Make Tofu Sisig
- Press the tofu. Wrap each tofu block in paper towels, place on a wire rack or plate, and weigh down with something heavy. Press for 15-20 minutes. Unwrap, pat dry again, and cut into ¾-inch cubes.
- Coat and fry. Toss the tofu cubes in cornstarch until lightly coated on all sides. Heat about 2 cups of oil in a wok or deep pan over medium-high heat to around 350-370°F. Fry the tofu in batches - don't crowd the pan. Cook until golden brown and crispy on all sides, about 4-5 minutes per batch. Remove with a slotted spoon and drain on a paper towel-lined plate. Season with a pinch of salt while still hot.
- Sauté aromatics. Discard the frying oil or pour it off. In a clean wide skillet over medium heat, melt the butter. Add the garlic and cook until golden, about 1 minute. Add the onion (reserving a small amount of raw red onion for garnish) and bell peppers. Sauté for 2-3 minutes until slightly softened but still with texture.
- Add the sauce. Add the calamansi or lemon juice, oyster sauce, and Maggi seasoning or soy sauce. Stir to combine and cook for 1 minute.
- Add the tofu. Add the crispy tofu to the pan. Toss gently to coat in the sauce - you want every piece coated but you also don't want to break the crust. Cook together for 1-2 minutes.
- Add mayo off the heat. Turn off the heat (or reduce to the lowest setting). Add the Kewpie mayo and fold it in gently until the tofu is evenly coated and creamy. Adding mayo over high heat causes it to separate and turn oily - off-heat is the move.
- Add chili. Stir in the sliced Thai chili if using.
- Serve. Transfer to a serving dish or sizzling plate (see below). Garnish with the reserved raw red onion slices, sliced green onions, and calamansi halves on the side for squeezing. Add a fried or raw egg on top if serving on a sizzling plate.
Variation
- Mushroom Sisig: Replace tofu with sliced mushrooms for a meaty, plant-based version.
- Chicken Sisig: Use diced chicken breast for a leaner, protein-packed option.
- Seafood Sisig: Try shrimp or squid for a coastal-inspired twist.
- Spicy Sisig: Add extra Thai chilies or a dash of hot sauce for a fiery kick.
- Vegan Sisig: Use vegan mayo and oyster sauce to keep it entirely plant-based.
- Tofu & Pork Combo: Add crispy pork belly for a hybrid sisig experience.
- Cheesy Sisig: Sprinkle shredded cheese on top for a creamy, indulgent touch.
- Sisig Rice Bowl: Serve the tofu sisig over steamed rice for a complete meal.
What To Serve With This?
- Garlic Rice: Elevates the savory flavors of the sisig.
- Steamed Jasmine Rice: A classic pairing that complements the dish’s bold flavors.
- Fried Egg: Top your sisig with a sunny-side-up egg for added richness.
- Atchara: Sweet pickled papaya is a traditional Filipino pairing.
- Lumpiang Shanghai: Crispy spring rolls add a delicious textural contrast.
- Beer: The bold flavors of sisig pair wonderfully with an ice-cold brew.
Air Fryer Tofu Option
For a lower-oil version, air fry the pressed, cornstarch-coated tofu at 400°F for 12-15 minutes, shaking the basket halfway through, until golden and crispy. The result is slightly less crunchy than deep-frying but significantly less oil-heavy. Proceed with the same sauce steps after air frying.
Rose's Tips
- Press properly. Fifteen to twenty minutes with weight on top. Not a quick pat with a paper towel. This is the single most impactful step for crispiness.
- Cornstarch over flour. Thinner, crispier, holds up better in the sauce.
- Fry in batches. Crowding the pan drops the oil temperature and causes the tofu to steam rather than fry. Work in 2-3 batches for a full two blocks of tofu.
- Season hot. Salt the tofu immediately after it comes out of the oil while it's still hot - seasoning sticks better and penetrates more effectively.
- Mayo goes in last, off the heat. This is the step most recipes get wrong. Mayo added over high heat breaks and turns greasy. Turn off the heat, then fold in the mayo.
- Raw onion garnish. Reserve some of the red onion raw and scatter it on top at the end. The sharpness of raw onion against the creamy, cooked base is a traditional sisig contrast that adds texture.
- Doesn't reheat well. Like most mayonnaise-based dishes, tofu sisig is best eaten fresh. The mayo separates on reheating and the tofu loses its crispiness. Make what you'll eat. If you do have leftovers, reheat in a dry skillet over medium heat rather than the microwave - it won't be as creamy but the texture holds better.
Storage
Tofu sisig is best eaten immediately. The mayonnaise separates and the tofu softens significantly within a few hours. If you have leftovers, store in an airtight container in the fridge for up to 2 days. Reheat in a dry skillet over medium heat - do not microwave, which makes the tofu rubbery and the mayo oily.
