So, you’ve got these giant, green banana-looking things sitting on your counter. You bought them because they looked exotic or maybe you saw a recipe for tostones and thought, "Yeah, I can do that." But now you're staring at them. They’re hard. They aren't peeling like a Cavendish. Honestly, the first thing you need to know about how do you make plantains is that they are basically potatoes that grow on trees. If you try to eat them raw, you’re going to have a bad time. It’s a starchy, chalky experience that nobody deserves.
I've seen people throw them away because they turned black. That is a tragedy. A black plantain is a gift from the culinary gods. It’s like throwing away a perfectly aged steak because it didn't look like the bright red ones in the grocery store case.
The Three Stages of a Plantain's Life
You have to time your cooking to the color of the skin. It's not just an aesthetic thing; the chemistry inside that fruit changes every single day it sits in your fruit bowl.
Green is for Crunch
When the plantain is green, the starch hasn't even thought about turning into sugar yet. It’s dense. It’s savory. This is what you use for tostones (twice-fried slices). You have to use a knife to peel these because the skin is basically armor. If you try to peel a green plantain like a banana, you'll just end up with bruised fingernails and a lot of frustration. Score the skin lengthwise and pry it off in chunks.
Yellow is the Middle Ground
Yellow plantains with some black spots are getting sweet, but they still hold their shape. They're okay for boiling or throwing into a stew. Some people like them fried at this stage, but they lack the structural integrity of the green ones and the gooey caramelization of the black ones. It's the awkward teenage phase.
Black is Gold
Wait. Just wait. When that plantain looks like it should have been in the compost bin three days ago, that's when you make maduros. The skin will be thin, almost papery, and the fruit inside will be soft. This is when the natural sugars are peaking. This is the peak of human achievement in the world of side dishes.
How Do You Make Plantains into Tostones?
This is the classic Latin American preparation. You need green plantains, a heavy pan, and enough oil to make your doctor slightly nervous.
First, cut the plantain into rounds, maybe an inch thick. You fry them once in medium-hot oil—not screaming hot, just enough to soften them. They shouldn't brown much. Pull them out. Now comes the weird part: you have to smash them.

In Puerto Rico or the Dominican Republic, they use a tostonera, which is just two pieces of wood on a hinge. If you don't have one, the bottom of a heavy mug or a small frying pan works perfectly. Smash those rounds until they're flat discs. Then, you fry them again. This second fry is where the magic happens. The edges get crispy and lacy, while the middle stays slightly chewy.
A lot of people forget the salt. Salt them immediately when they come out of the oil. Better yet, dunk them in a little bowl of garlic water (water, crushed garlic, salt) for three seconds before that second fry. It sounds dangerous—water in oil—and it is, so be careful. It creates a steam effect that makes the inside fluffier.
The Art of the Sweet Maduro
If you're wondering how do you make plantains that taste like candy without adding any sugar, you go for the maduros. You need those black-skinned beauties we talked about earlier.
Slice them on a long bias. You want surface area. More surface area means more caramelization. Drop them into a pan with just enough oil to coat the bottom. You don't need to deep fry these. In fact, if you deep fry maduros, they often soak up too much oil and get greasy.
Medium-low heat is your friend here. Because of all that sugar, they will burn in a heartbeat if the flame is too high. You’re looking for a deep, mahogany brown. They should be soft enough to cut with a spoon. Some people serve these with a dollop of sour cream or crema, and the contrast between the hot, sweet fruit and the cold, tangy cream is honestly one of the best flavor profiles on the planet.

What Most Recipes Don't Tell You
There is a massive debate about soaking. Some Caribbean cooks swear by soaking green plantain slices in salted water for 15 minutes before the first fry. They claim it removes excess starch and keeps them from oxidizing (turning brown). Does it work? A little bit. Is it necessary? Not really, unless you're prepping a massive batch for a party.
Also, let's talk about air fryers. Can you make plantains in an air fryer?
Yes, but with a caveat. For maduros, it works surprisingly well because the hot air mimics the caramelization process. Just toss them in a tiny bit of oil first. For tostones, it’s harder. The "smash" phase requires the plantain to be softened by oil to get that specific texture. If you air fry them for the first "cook," they tend to get dry and crumbly when you try to flatten them. If you're health-conscious, go for it, but just know they won't have that iconic "shatter" when you bite into them.
Boiling: The Healthy Alternative
In many West African and Caribbean households, boiling is just as common as frying. You can boil green plantains in their skin (just cut the ends off) in salted water for about 20-30 minutes. Once they're soft, peel them and mash them with a little butter or olive oil. In the Dominican Republic, this is the base for Mangú. It’s often topped with pickled red onions, and it’s the kind of breakfast that stays with you until dinner. It's heavy, it's hearty, and it's incredibly cheap to make.
Common Mistakes to Avoid
- Using the wrong ripeness: Trying to make sweet plantains with green fruit. It won't happen. You can't force it.
- Crowding the pan: If you put too many slices in at once, the oil temperature drops. Instead of frying, the plantains just start braising in lukewarm grease. They'll come out soggy.
- Fear of the black peel: I'll say it again. If it's black, it's not rotten. Unless it smells fermented or there’s mold, a black plantain is exactly what you want for dessert or a sweet side.
- Skipping the salt: Plantains are incredibly bland on their own. They need salt to bridge the gap between the starch and the flavor. Even the sweet ones benefit from a tiny pinch of flaky sea salt.
Why Nutrient Density Matters
Plantains aren't just empty carbs. They are loaded with potassium—even more than a standard banana—and they’re a great source of fiber and Vitamin A. According to the USDA, a single cup of cooked plantains provides a significant chunk of your daily Vitamin C and magnesium requirements. Because they are a complex carbohydrate, they digest slower than white bread or pasta, providing a steadier release of energy. This is why they’ve been a staple crop for centuries across the tropical belt of the world.
Sourcing and Storage
Most grocery stores carry them now. Look for them near the bananas or in the "ethnic" produce section. If you only see green ones and you want sweet ones, buy them anyway. Put them in a paper bag with an apple or just leave them on top of your fridge where it's warm. In five to seven days, they'll be ready. If they get ripe before you're ready to cook them, throw them in the fridge. The skin will turn black even faster, but the fruit inside will stop ripening, buying you another two or three days.

- Go to the store today and buy three green plantains and three that are already starting to yellow.
- For the green ones: Peel them, slice them into rounds, and try the double-fry method for tostones tonight. Serve them with a simple dipping sauce of mayo, ketchup, and a squeeze of lime.
- For the yellow/black ones: Leave them on the counter. Forget about them for four days. When they look ugly, slice them thin and pan-sear them in a little butter or coconut oil until they are dark brown.
- Experiment with heat: If you like spicy food, sprinkle some cayenne or chipotle powder on your fried plantains. The sweetness of the fruit plays incredibly well with smoky heat.
- Try a mash: If you have leftovers, mash them up with some sautéed onions. It’s a great base for a bowl with black beans and avocado.
The beauty of the plantain is its versatility. It can be a chip, a fry, a mash, or a dessert. Once you figure out the timing of the ripeness, you'll wonder why you ever settled for just potatoes.
