How long should you boil pineapple skin?

Pineapples are a delicious and nutritious tropical fruit that are loved by many. However, preparing fresh pineapple requires removing the tough, spiky skin before eating. Some people choose to boil the pineapple skin first to make it easier to peel. But how long should you actually boil pineapple skin for best results?

Why Boil Pineapple Skin?

Boiling pineapple skin serves two main purposes:

  1. It softens the skin, making it easier to remove.
  2. It helps remove any dirt or chemicals on the surface.

Pineapple skin contains a mixture of enzymes that give it its rigidity. By boiling, these enzymes get partially broken down, causing the skin to become softer and less firmly attached to the fruit. Boiling also cleans the skin by removing any residues from processing, storage, transport or handling.

How Long to Boil For

Most sources recommend boiling pineapple skin for 5-10 minutes to get it soft enough to peel, without overcooking the fruit inside. The exact time needed depends on:

  • Ripeness – Riper pineapples will need less time to soften than unripe ones.
  • Size – Larger pineapples require longer boiling.
  • Thickness – Thicker, tougher skin needs more time to soften.
  • Altitude – Water boils at lower temperatures at higher elevations, so skin will take longer to soften.

For a standard sized ripe pineapple at sea level, boiling the skin for 7-8 minutes is usually sufficient.

Step-by-Step Boiling Instructions

Follow these simple steps for boiling pineapple skin:

  1. Wash the pineapple thoroughly under running water to remove any dirt or debris.
  2. Using a sharp knife, slice off the top and bottom of the pineapple.
  3. Stand the pineapple upright and slice off the skin from top to bottom, cutting deep enough to remove the eyes and skin, but not too deep into the flesh.
  4. Cut the peeled pineapple into rounds or chunks as desired.
  5. Place the pineapple pieces into a pot and add enough water to just cover them. Bring to a boil over high heat.
  6. Once boiling, reduce heat and simmer for 7-8 minutes, until the skin seems softened and easily pierced with a fork.
  7. Remove pot from heat and drain off the water. Rinse pineapple under cool water to stop further cooking.
  8. At this point, the skin should peel off easily. If not, return pineapple to pot, cover again with water and simmer for 2-3 more minutes until soft enough.
  9. Peel skin with hands or a paring knife. Slice, dice or chop the pineapple and enjoy!

Boiling Whole Pineapples

You can also boil a whole pineapple without cutting it first. This takes longer but simplifies the process. To boil a whole pineapple:

  1. Clean and trim the top and bottom as above.
  2. Place the pineapple in a large pot and add enough water to cover it completely.
  3. Bring to a boil over high heat, then reduce to a simmer.
  4. Simmer for 15-20 minutes for a medium size pineapple until fork tender.
  5. Drain and let cool until safe to handle. The skin should peel away easily.

The advantage of boiling whole is that the fruit inside cooks slightly and retains more flavor and juice. However, it takes longer and uses more water.

Tips for Boiling Pineapple Skin

Follow these tips for best results when boiling pineapple skin:

  • Use very ripe, fragrant pineapples – underripe ones won’t soften as well.
  • Trim ends neatly to allow water to penetrate the skin.
  • Use a large pot so pineapple is covered with water.
  • Bring water to a rapid boil before adding pineapple.
  • Reduce to a gentle simmer to prevent overcooking.
  • Test doneness frequently until you learn timing.
  • Remove from heat as soon as soft – do not over boil.
  • Drain and rinse with cool water to stop cooking.

What About Microwaving?

Some people advocate microwaving pineapple skin instead of boiling to soften it. This does work, but boiling is preferable for several reasons:

  • Microwaving cooks the fruit unevenly, creating hot spots.
  • It’s harder to control and time accurately.
  • The skin may become very hot and risky to handle safely.
  • Moisture from boiling helps loosen skin making it easier to peel.
  • Boiling cleans and removes residues from the skin surface.

If you do microwave, place pineapple pieces skin-side down in a microwave-safe dish. Microwave on high for 30-60 seconds per slice. Check frequently and stop when skin feels softened. Use potholders to handle safely.

Can You Eat Boiled Pineapple Skin?

While boiling softens pineapple skin enough to peel it, the skin is still not considered edible. Pineapple skin contains high amounts of fiber and enzymes that are tough to digest. Boiling does not break these down enough to make the skin palatable. So it’s still best to peel and discard the skin after boiling.

However, the boiled pineapple flesh is perfectly safe to eat and requires no special preparation before enjoying!

Uses for Pineapple Skin

While not edible, boiled pineapple skin still has uses, including:

  • Compost – High in fiber, pineapple skin breaks down well into nutritious compost for gardens.
  • Broth – Add to vegetable or chicken broth for a tropical flavor.
  • Marinade – Blend with oil, vinegar and spices to marinate meats.
  • Pineapple vinegar – Ferment skins to infuse vinegar with pineapple flavor.
  • Tea – Pineapple skins can be dehydrated and infused into tea.
  • Fruit enzyme drink – Blend boiled skins into a healthful enzyme tonic.

So don’t discard that boiled pineapple skin – take advantage of this nutritious tropical treat!

Nutrition of Pineapple Flesh vs. Skin

Here is a comparison of the nutrition in pineapple flesh (per 100g) versus pineapple skin:

Nutrient Pineapple Flesh Pineapple Skin
Calories 50 21
Protein 0.5g 0.5g
Carbs 13.1g 5.4g
Fiber 1.4g 4.1g
Sugar 10.1g 2.4g
Fat 0.1g 0.2g
Vitamin C 47.8mg 8.7mg
Manganese 0.9mg 0.5mg

As shown, pineapple flesh is higher in calories, sugar, and vitamin C compared to the skin. But pineapple skin contains a lot more fiber. The skin also provides some nutritional benefits, though not as much as the flesh.

Downsides of Eating Pineapple Skin

Although boiling softens pineapple skin, it is still not recommended to eat it. Here are some downsides of consuming boiled pineapple peel:

  • Digestive issues – The tough fiber and enzymes can be hard to break down and cause gas or bloating.
  • Mouth irritation – The skin fibers can scrape or scratch delicate mouth tissues.
  • Blocked intestines – Indigestible skin pieces could potentially cause an intestinal obstruction.
  • Pesticides – Any chemicals on the skin could be harmful, even after boiling.
  • Bromelain allergy – Those allergic to pineapple enzymes may react to the skin.

So while the skin does contain some beneficial nutrients, the potential risks of eating it after boiling outweigh any small benefits.


Boiling pineapple skin for 5-10 minutes is an easy way to soften it for peeling. Allowing more time for larger or underripe fruits. Though edible pineapple flesh results, the skin itself remains too fibrous and indigestible to eat after boiling. But the softened peel can still be used creatively in recipes or composting. Boil pineapple skin just long enough to peel it, then discard and enjoy the nutritious, tropical fruit inside.
