Tostones Cooking Method for Crisp, Golden Plantains

Tostones are twice-fried green plantain slices, a popular side dish and snack across the Caribbean and parts of Latin America. The first fry softens the plantain, then flattening and frying it again creates crisp edges and a tender center; serve them hot with salt and a dipping sauce.

Ingredients

2 large unripe green plantains, about 1½ lb (680 g) total
4 cups neutral frying oil, such as canola or peanut oil, about 950 ml, or enough for a depth of 1½ inches (4 cm) in a heavy pot
1 teaspoon fine salt, 5 g, plus more to taste
2 cups water, 475 ml, optional, for briefly dipping the flattened plantains
2 garlic cloves, finely grated or crushed, optional, for the dipping water

Instructions

Peel and cut the plantains. Trim off both ends. Score the peel lengthwise in two or three places, cutting through the skin without slicing deeply into the flesh. Pry off the peel with your fingers or the tip of a small knife. Cut each plantain crosswise into pieces about 1 inch (2.5 cm) thick. Keep the pieces fairly even so they cook at the same rate.
Heat the oil. Pour oil into a sturdy, deep pot, leaving plenty of space at the top to prevent splashes. Heat over medium to medium-high until it reaches 325–350°F (163–177°C) on a frying thermometer. If you do not have a thermometer, add one plantain piece: steady bubbles should form around it without the oil smoking. Adjust the heat as needed; smoking oil is too hot.
Fry the plantain pieces once. Carefully lower the pieces into the oil in batches, leaving room around each one. Fry for 3–4 minutes, turning once, until they are softened and pale golden but not deeply browned. Avoid crowding the pot, which can lower the oil temperature and make the plantains greasy. Lift them out with a slotted spoon and place them on a paper-towel-lined plate or rack. Turn off the burner briefly if needed while you flatten the pieces.
Flatten each piece. While the plantains are warm, set one piece between sheets of parchment or inside a cut-open food-safe plastic bag. Press with the bottom of a small plate, a flat measuring cup, or a tostonera until it is about ¼ inch (6 mm) thick. Press firmly enough to spread it, but not so hard that it breaks apart. Repeat with the remaining pieces.
Season or dip, if desired. For a simple garlic dip, stir the crushed garlic into the measured water. Briefly dip each flattened piece, about 1 second per side, then let excess water drip off and pat the surface dry. This step is optional: it adds garlic flavor, but water left on the plantains can make hot oil splatter. For the least splattering, skip the dip and season after frying.
Fry a second time. Bring the oil back to 325–350°F (163–177°C). Fry the flattened plantains in batches for 2–3 minutes, turning once, until crisp and golden at the edges. Transfer to a rack or paper towels and sprinkle with salt while hot. Serve promptly for the best crunch.

Tips

Choose green plantains. Firm, green-skinned fruit is starchy and holds its shape. Yellow or black plantains are sweeter and softer, so they will not produce the same savory, crisp tostones.
Peel more easily with shallow scoring. Green plantain skins can cling tightly. Cut only through the peel, then use your fingers to loosen it; avoid taking off thick layers of the flesh.
Keep the oil temperature steady. Fry in small batches and let the oil return to temperature between them. A thermometer helps, but if the oil smokes, take the pot off the heat and let it cool before continuing.
Flatten while warm, and handle hot oil carefully. Warm plantains are easier to press. Use a utensil to move pieces in and out of the oil, keep water away from the pot, and never leave hot oil unattended.

Serving Suggestions

Serve tostones immediately as a side for rice and beans, grilled fish, roast pork, or stewed chicken. They are also good as a snack with a garlicky mayonnaise, cilantro-lime sauce, or a simple dip made from mashed avocado, lime juice, and salt. For a classic savory finish, offer a small bowl of salt and a dish of garlic sauce at the table.

Because they crisp as they cool, arrange them in a single layer rather than stacking them in a covered bowl. If serving a larger meal, fry the first round shortly before guests arrive, then flatten and complete the second fry just before eating.

Variations

Garlic-lime tostones: Add the crushed garlic to the optional dipping water, then finish the fried plantains with a squeeze of lime. Pat them very dry after dipping to reduce splattering.

Herb and spice finish: Toss the hot tostones lightly with salt and a pinch of ground cumin, smoked paprika, or finely chopped cilantro. Start with a small amount so the seasoning does not hide the plantain’s mild flavor.

Loaded tostones: Use the flattened pieces as crisp bases for black beans, avocado, shredded cabbage, or cooked shredded meat. Add toppings just before serving to keep the plantains from becoming soggy.

Oven-finished option: Tostones are traditionally fried twice, and baking will not make an exact substitute. For a less oily variation, brush both sides of the flattened pieces with oil and bake on a parchment-lined sheet at 425°F (220°C), turning once, until browned and firm, about 15–20 minutes. The result is usually less crisp than the classic fried version.

Storage and Reheating

Tostones are best eaten right after frying. Refrigerate leftovers within 2 hours in a covered container and use within 3–4 days. They soften in storage, so avoid stacking them while warm; let them cool first and separate layers with parchment. For longer storage, freeze them in a single layer until firm, then transfer to a freezer-safe bag for up to 2 months.

Reheat refrigerated or frozen tostones in a 400°F (200°C) oven or air fryer until hot and crisp, turning once; allow a little extra time if reheating from frozen. A microwave warms them but leaves them soft. Discard plantains left at room temperature for more than 2 hours, or more than 1 hour when the temperature is above 90°F (32°C).

Frequently Asked Questions

Can I make tostones without a thermometer?
Yes. Heat the oil over medium to medium-high and test it with one piece: bubbles should appear steadily, but the oil should not smoke. Fry a small batch first and adjust the heat if the pieces brown too quickly or absorb oil.

Why are my tostones soggy?
The oil may have been too cool, the pot may have been crowded, or the pieces may have been covered while hot. Keep batches small, maintain the frying temperature, drain on a rack or paper towels, and serve soon after the second fry.

Can I prepare them ahead?
You can complete the first fry and flatten the plantains a few hours ahead. Cool them promptly, cover, and refrigerate; then fry them a second time just before serving. Do not leave partially cooked plantains at room temperature for more than 2 hours.

What can I use to flatten plantains?
A tostonera is designed for the job, but the bottom of a small plate, a flat cup, or a meat mallet also works. Place parchment or a cut-open food-safe bag between the plantain and the pressing surface to reduce sticking.

Can I use ripe plantains instead?
Ripe yellow or black plantains are sweeter and softer, and they are more likely to break when pressed. They are better suited to other preparations; for tostones, choose firm green plantains.

What oil works best for frying?
Use a neutral oil with a high smoke point, such as canola, peanut, or vegetable oil. Olive oil can add a strong flavor and is not the best choice for maintaining the fairly high frying temperature needed here.
