Tostones are a Latin food staple and a popular side dish in many Caribbean and South American countries. They are made with green (unripe) plantains, which are a variety of banana that must be cooked due to their high starch content. Traditionally, tostones are deep-fried twice in oil, but cooking them in an air fryer is a healthier alternative that uses less oil and yields a similar texture. So, how long do you cook tostones in an air fryer?

What You'll Learn

Selecting the right plantains
Tostones are traditionally made with green plantains, which are unripe and incredibly starchy. They are also very firm to the touch. As plantains ripen, they turn yellow, then brown, and finally black, and become progressively sweeter. Riper plantains are not suitable for tostones, as this dish is savoury. Therefore, when selecting plantains for tostones, it is best to choose ones that are green and firm.
It is also important to avoid plantains with a lot of yellow on the peel, as these will be sweeter and less firm, which is not ideal for tostones. If you are unable to find green plantains, you could try using slightly riper ones, but be aware that they may not produce the desired result.
When preparing plantains for tostones, you will need to cut off both ends and make a slit along the length of the skin. It is important to only cut through the skin and not into the plantain flesh. You can then cut the plantain into 1-inch chunks and peel the skin off each piece.
Some recipes recommend peeling the plantain before cutting it into chunks. To do this, cut off both ends of the plantain and score the peel down the "back". You can then use your thumbs to remove the peel.
Once the plantains are prepared, you can cook them in your air fryer. Place the plantain chunks in the air fryer basket and spray them with olive oil. Air fry for 5 minutes, then remove from the air fryer and smash them to about 1/2-inch thickness using a tostonera or the bottom of a cup or jar.

Preparing the plantains
Once you have selected the right plantains, you will need to peel and cut them. Start by cutting off both ends of the plantain. Then, make a shallow cut along the length of the plantain, deep enough to penetrate the skin without cutting into the flesh. You can then use the fleshy part of your thumbs to remove the peel, or use a paring knife to help with peeling, especially if the plantain is not very fresh.
Next, cut the peeled plantain into slices. The thickness of the slices can vary depending on your preference, but they should be around 1 inch (2.5 cm) thick. If you are making smashed tostones, you will want the plantain slices to be thinner, around 1/2 inch thick.
Once your plantains are cut, you will need to coat them with oil. Place the plantain slices in a bowl and toss them with a tablespoon of cooking oil, making sure each slice is coated. You can also spritz the plantains with oil if you have an oil spray bottle.
Now your plantains are ready to be cooked in the air fryer! Place them in a single layer in the air fryer basket, leaving some space around each slice to allow for proper air circulation.

Cooking the plantains
Tostones are made from green, unripe plantains, which are a staple food in many Latin American countries. They are often twice-fried, but using an air fryer is a healthier alternative that still yields crispy tostones.
To cook plantains in an air fryer, start with a firm, green plantain. Cut off both ends of the plantain, then make a slit along the length of the skin deep enough to penetrate the skin without cutting the plantain itself. Cut the plantain into 1-inch chunks, then peel each piece. You can use a sharp knife to aid in removing the skin, or try peeling the plantain under warm water.
Place the plantain chunks in a bowl and toss with a tablespoon of cooking oil, coating each piece. Transfer the plantains to the air fryer basket, ensuring they are not piled on top of each other, and leaving space for air to circulate. Fry until the plantain offers no resistance when pierced with a knife, which can take 3-6 minutes per side.
Remove the plantain slices from the basket and smash each one to a thickness of about 0.25-0.5 inches. A tostonera is typically used for this, but you can also use the bottom of a cup, mug, or jar. Soak the smashed tostones in a bowl of salted water for a few seconds, then pat dry with a paper towel.
Return the tostones to the air fryer basket in batches, ensuring a single layer with space for air circulation. Spray the tops with cooking oil and season with salt. Air fry for 4-5 minutes, then flip the tostones and spray the other side with oil and season with salt. Air fry for another 4-5 minutes, until golden brown and crisp.
Tostones are typically salted and served as a side dish, similar to chips. They can be paired with a variety of dipping sauces, such as mayonnaise-ketchup, guacamole, salsa, or ceviche.

Flattening the plantains
Tostones are made from green ?(unripe)? plantains and are a popular side dish in many Caribbean and South American countries. They are sometimes called patacones, and are twice-fried, crispy plantains.
To flatten the plantains, you will need to first trim the ends off the plantain and then cut a slit along the length of the skin. The slit should be deep enough to penetrate the skin without cutting the plantain itself. You can then peel the plantain, and cut it into 1-inch chunks.
The next step is to par-fry the plantain chunks. To do this, place the plantain chunks in your air fryer basket and spritz them with oil. Air fry for 5-6 minutes. Remove the plantain pieces from the air fryer and smash them to about 1/4-1/2 inch thickness using a tostonera (plantain smasher). If you don't have a tostonera, you can use the bottom of a cup, mug, or jar to flatten the plantains.
After smashing the plantains, you can soak them in a bowl of salted water for a few seconds before returning them to the air fryer for the final crisping fry.

Seasoning the plantains
Tostones are made with green (unripe) plantains, which are a very popular side dish in many Caribbean and South American countries. They are a variety of banana that must be cooked because of the amount of starch they contain. They are often twice-fried and served with salt.
When selecting your plantains, they should be a verdant green colour and very firm. Avoid plantains with a lot of yellow in the peel as they have already started to ripen and will taste sweeter.
To peel a green plantain, cut off both ends of the plantain and score the peel by cutting down the “back” of the plantain. Use the fleshy parts of your thumbs to remove the plantain’s fibrous peel. Make a vertical cut in the skin from end to end, ensuring you only cut through the thick skin and not into the plantain flesh.
Once peeled, you can cut the plantain into 1-inch chunks or slices. If you are finding it difficult to cut the plantain, you can use a case knife to aid in removing the skin, or try to peel them while under warm water.
Now it's time to season! There are a few different ways to season your plantains for tostones. One popular method is to use a salt water brine. You can prepare this by adding salt and garlic powder to a bowl of water. You can also add minced garlic and fresh lime juice to the brine to create a garlic-lime water soak, which will infuse your tostones with extra flavour and create a fluffier interior. It will also help to prevent the tostones from oxidising and turning brown.
Another option is to simply season your plantains with salt after frying, sprinkling it on top, or serving them with a dip such as guacamole, ceviche, zesty avocado dressing, or mayo-ketchup.
