Indonesian tuna balado is made by searing tuna and coating it in a lively sambal of chilies, shallots, garlic, and tomato. This home-style version balances heat with lime and a little sugar, making a satisfying main dish to serve with rice and vegetables.
Balado is a broad Indonesian cooking style built around a spicy chili sauce, and recipes vary by region and household. Here, the tuna is cooked first so it stays in neat portions, then briefly simmered in the sauce to pick up its flavor without falling apart.
Ingredients
- 1 1/2 pounds (680 g) tuna steaks, about 1 inch (2.5 cm) thick, cut into 4 portions
- 1 teaspoon (5 ml) fine salt, divided, plus more to taste
- 1/2 teaspoon (1.5 g) ground turmeric
- 3 tablespoons (45 ml) neutral cooking oil, divided
- 6 medium shallots, about 3 ounces (85 g), peeled and finely chopped
- 4 garlic cloves, about 12 g, peeled and finely chopped
- 4 red Fresno or similar mild red chilies, about 2 ounces (55 g), stemmed and finely chopped
- 1 or 2 Thai bird’s-eye chilies, about 4 g total, finely chopped (optional, for extra heat)
- 1 medium ripe tomato, about 5 ounces (150 g), finely diced
- 1 teaspoon (4 g) granulated sugar
- 1/4 cup (60 ml) water
- 1 tablespoon (15 ml) fresh lime juice, plus lime wedges for serving
Fresno chilies give the sauce color and moderate heat; red jalapeños work too, though they can taste greener. Thai bird’s-eye chilies are optional, so leave them out for a milder sauce or add just one for a noticeable kick. Shallots are common in Indonesian cooking, but a small red onion is a practical substitute; it makes the sauce a little sharper and less sweet.
Instructions
- Prepare the tuna and aromatics. Pat the tuna dry with paper towels. Season both sides with about 3/4 teaspoon of the salt and all the turmeric. Chop the shallots, garlic, chilies, and tomato before heating the pan; keeping the sauce ingredients ready makes the short cooking process easier to manage.
- Sear the tuna, about 12 minutes. Heat 1 tablespoon (15 ml) of the oil in a large skillet over medium-high heat for about 2 minutes. Cook two tuna portions at a time, searing for about 3 minutes per side, then transfer them to a plate while you cook the remaining portions. Avoid crowding the pan, which can make the fish release moisture and steam rather than brown. Cooking time varies with thickness, so check the center of the thickest portion with a food thermometer. USDA FSIS guidance sets the safe minimum internal temperature for fish at 145°F (63°C).
- Make the sambal, about 5 minutes. Reduce the heat to medium and add the remaining 2 tablespoons (30 ml) oil to the skillet. Add the shallots, garlic, Fresno chilies, and bird’s-eye chilies, if using. Stir for about 2 minutes, until softened and fragrant but not browned. Add the tomato, sugar, remaining 1/4 teaspoon salt, and water. Cook for about 3 minutes, stirring and pressing the tomato with the spoon until it softens into a chunky sauce.
- Finish the dish, about 1 minute. Return the tuna and any juices on the plate to the skillet. Spoon sambal over the fish and turn the pieces gently once so they are coated. Simmer for about 1 minute, just to bring the fish and sauce together, then take the skillet off the heat and stir in the lime juice. Taste the sauce and adjust with a pinch of salt, sugar, or more lime as needed. Serve promptly, with extra sauce spooned over each portion.
The sauce should be moist and spoonable rather than watery. If the tomato has released little liquid, add a tablespoon or two of water while it cooks; if it looks too loose, simmer it briefly before returning the tuna. A few small flakes at the edges of the fish are normal, but avoid stirring vigorously because tuna steaks can break apart.
Tips
- Choose evenly thick portions. Tuna steaks of similar thickness finish at roughly the same time. If one portion is much thinner, check it early and remove it as soon as it reaches 145°F (63°C); return it to the sauce only for the final brief simmer.
- Keep the heat manageable. Chilies vary considerably in strength. Start without the bird’s-eye chilies, taste the sauce after the tomato softens, and add a little more heat only if you want it. Handle hot chilies carefully and wash your hands and cutting board after chopping them.
- Use a ripe tomato and taste at the end. A ripe tomato softens quickly and brings acidity that keeps the sambal from tasting heavy. Lime, salt, and sugar are there to balance the particular tomato and chilies you have, not to make the sauce taste sweet or sour on its own.
- Do not leave the fish unattended. Tuna can go from moist to dry quickly, especially if the steaks are thinner than an inch. Use the thermometer rather than relying only on color, and cook in batches if the skillet is crowded.
Serving Suggestions
Serve tuna balado hot with steamed jasmine or other long-grain rice, which soaks up the chili-tomato sauce. For a meal with more contrast, add sliced cucumber, blanched green beans, or lightly sautéed greens. A simple vegetable side is especially useful if the sambal is quite hot; its fresh, mild flavor gives the palate a break between bites.
Put lime wedges on the table so each person can brighten their serving, and offer extra sauce separately if someone prefers less chili. For a family-style meal, arrange the tuna on a shallow platter and spoon the sambal over the top rather than stirring it repeatedly in the pan. This keeps the portions intact and makes it easy to distribute the sauce evenly.
Variations
Make it gentler. Use only Fresno chilies and remove their seeds and inner ribs before chopping. You can also reduce the chilies to two or three; the sauce will be less fiery and somewhat milder in flavor, but the shallots, garlic, and tomato still make it savory.
Add kecap manis. For a sweeter, deeper variation, stir 1 tablespoon (15 ml) Indonesian sweet soy sauce into the tomato mixture. Kecap manis is thicker and sweeter than ordinary soy sauce. If it is unavailable, use 2 teaspoons (10 ml) regular soy sauce plus 1 teaspoon (5 ml) brown sugar; the result will be less syrupy and not quite as complex.
Use another fish. Firm, thick-cut salmon or mahi-mahi can stand up to the sauce, though the flavor will differ from tuna. Check the thickest part with a thermometer and cook fish to 145°F (63°C). Avoid very thin fillets, which can overcook while the sauce is being made.
Use canned tuna for a pantry version. Drain two 5-ounce (142 g) cans of tuna well, make the sambal as directed, and fold the tuna into the finished sauce just long enough to heat it through. The texture will be softer, and you will miss the browned edges of seared steaks, but it is a practical option when fresh tuna is unavailable.
Storage and Reheating
Transfer leftover tuna and sauce to a covered, shallow container and refrigerate within 2 hours of cooking. Keep it refrigerated for 3 to 4 days. The sauce can be made a day ahead and refrigerated separately; for the best texture, cook the tuna close to serving time rather than searing it far in advance.
Reheat leftovers gently in a covered skillet over low heat with a tablespoon of water, turning the fish carefully so the sauce warms evenly. Check that leftovers reach 165°F (74°C), the USDA FSIS safe reheating temperature. A microwave also works: cover the dish, heat in short intervals, and check the center with a food thermometer. Repeated heating can dry the tuna, so warm only the amount you plan to eat. Freeze leftovers in a sealed freezer-safe container for up to 2 months for best quality; thaw overnight in the refrigerator and reheat to 165°F (74°C).
Frequently Asked Questions
Can I make Indonesian tuna balado less spicy?
Yes. Leave out the bird’s-eye chilies, use fewer Fresno chilies, and remove the seeds and pale ribs before chopping. The sauce will still have a chili flavor, but the heat will be gentler. If you are serving people with different preferences, keep extra chopped chili or chili sauce on the side rather than making the whole pan hotter.
Can I use frozen tuna?
Yes. Thaw it in the refrigerator overnight, then pat it thoroughly dry before seasoning and searing. Surface moisture makes browning harder and can cause oil to spatter. Do not thaw fish on the counter. If the steaks are uneven after thawing, cook thinner pieces for less time and use the thermometer to check each one.
Can I prepare the sambal ahead?
Yes. Cook the sauce through the tomato step, cool it, and refrigerate it in a covered container for up to 3 days. When ready to eat, warm the sauce in a skillet, add the freshly seared tuna, and finish with lime. This separates the make-ahead work from the brief final cooking and helps the tuna keep a better texture.
Why did my tuna turn out dry?
It may have cooked too long, particularly if the steaks were thinner than the recipe’s approximate 1-inch portions. Tuna continues to cook slightly after leaving the pan, and a long simmer in the sauce can dry it further. Check the thickest part with a thermometer, take the pan off the heat once the fish reaches 145°F (63°C), and keep the final simmer brief.
What can I use instead of a skillet?
A wide sauté pan works well, as does a heavy frying pan large enough to hold the fish without crowding. If you only have a smaller pan, sear the tuna in batches and make the sambal after all the fish is cooked. Avoid using a pan so deep that the fish is submerged in oil; this recipe is designed for searing, not deep-frying.
