Acorn Squash: Storage, Shelf Life, and Cooking Methods

How Long Does Acorn Squash Last?

Acorn squash boasts an impressive shelf life compared to many other fresh produce items. However, its longevity depends on whether it’s cooked or not.

Whole and Raw

A perfectly ripe acorn squash, characterized by its heavy weight, firm texture, and lack of blemishes, can last for 1 to 2 months in a cool, dry place away from direct sunlight.

Tip: According to Oregon State University Extension, storing a whole squash at around 50 degrees Fahrenheit is ideal. While refrigeration may seem like a good option, temperatures below 50 degrees can actually accelerate spoilage in uncooked acorn squash.

Cooked and Peeled

If you have an acorn squash that’s been sitting in your pantry for a while, cooking it can extend its life by a few extra days.

Here’s how to cook it:

  1. Pierce the rind all over with a sharp knife.
  2. Bake the whole squash at 400 degrees Fahrenheit for about 45 minutes or microwave it for around 12 minutes.
  3. Once cool, slice it in half, remove the seeds, and scoop out the flesh.

Cooked acorn squash can be stored in an airtight container in the refrigerator for up to 3 days.

Mashed and Frozen

For long-term storage, consider freezing your acorn squash. Properly prepared, it can last in the freezer for up to a year without compromising its quality.

Preparation steps:

  1. Cook the squash.
  2. Allow it to cool completely.
  3. Mash or puree the flesh.
  4. Freeze it in an airtight, dated container.

To use, thaw the frozen squash in the refrigerator overnight.

How to Tell if Acorn Squash Has Gone Bad

Like all fresh vegetables, damaged acorn squash decays quickly. Here are some signs to watch out for:

  • Cracks or dents: Avoid squash with any physical damage.
  • Soft or glossy rind: A soft rind indicates watery, flavorless flesh, while a glossy rind suggests immature, bitter flesh.
  • Peak ripeness: Choose squash with a dull, deep green rind with splashes of bright orange. As the squash ages, the orange patches become larger, so avoid buying a mostly orange squash if you don’t plan to use it right away.

How to Cook Acorn Squash

Acorn squash is a versatile vegetable that can be cooked in various ways, including:

  • Roasting: This is the most common method, resulting in tender, flavorful flesh. Simply cut the squash in half, remove the seeds, and roast it in a preheated oven at 400 degrees Fahrenheit for 50 to 60 minutes.
  • Microwaving: For a quicker option, microwave the squash cut-side down in a microwave-safe dish with a little water for about 10 minutes.
  • Grilling: Wrap the squash halves in foil and grill over low heat until tender.

Tip: Acorn squash seeds are edible and can be roasted for a delicious and nutritious snack.

Additional Tips

  • When selecting an acorn squash, choose one that is heavy for its size and free of blemishes.
  • Store whole, uncooked acorn squash in a cool, dry place away from direct sunlight.
  • Cooked acorn squash can be stored in an airtight container in the refrigerator for up to 3 days.
  • For long-term storage, freeze mashed or pureed acorn squash in an airtight container for up to a year.
  • Acorn squash can be roasted, microwaved, or grilled.
  • The seeds are edible and can be roasted for a healthy snack.

By following these tips, you can enjoy fresh, delicious acorn squash for months to come.

Acorn Squash Selection

You must weigh and feel the texture of the acorn squash’s skin in order to evaluate the vegetable because it is difficult to determine its appearance. Its skin should be dull and smooth, with no soft spots at all, and it should feel heavy for its size. Acorn squash typically weighs one to three pounds when harvested when fully ripe; if it weighs more, you run the risk of receiving a dry, stringy squash. When comparing, keep in mind that a lighter weight acorn squash will be drier because it has lost moisture through the skin.

To indicate maturity, look for some partial orange on the skin. However, excessive orange coloring on the skin denotes an overripe squash that will be stringy and dry. A good balance between green and orange coloring is optimum. Shiny skin, unless the producer has applied wax, indicates that it was picked before it was fully mature.

Acorn Squash Storage

Store winter squash in a dark, cool place (between 50 and 55 degrees Fahrenheit) for up to a month; refrigerated, it will spoil after about two weeks. Acorn squash should ideally only be refrigerated when cut or cooked, as they will become damaged by low temperatures (below 50 F). A shorter shelf life will result from moisture loss caused by dry, hot air. Retaining some of the stem on squash will help reduce moisture loss.

Acorn squash should be used within two weeks of purchase because you can never be sure how long or under what circumstances it has been stored. Growing your own gives you greater control and allows for a longer storage period (two to three months). After cutting, place the raw parts in plastic wrap, chill, and use within four days. Refrigerating cooked acorn squash for up to four days can be done by sealing it.

Before freezing, acorn squash must be cooked. Cook squash and remove the pulp from the skin. You can leave it in chunks or mash it. Store in airtight jars and freeze for a maximum of six to twelve months.

The Best Way to Cook Acorn Squash (Seriously Good)

How long do acorn squash last?

A whole squash without any preparation can achieve a storage life of up to 2-3 months at temperatures of 50-60°F or 10-15°C. In hotter areas (room temperature 68°F or 20°C), the maximum storage time is 2 months from harvest. However, warm temperatures with high humidity only allow acorn squashes to stay fresh for a few weeks.

Are acorn squash seeds edible?

Acorn squash seeds are edible and are very easy to prepare. They are basically the same as pumpkin seeds and the best way to prepare them is to sprinkle a little salt on them and roast them in the oven. They don’t need to cook too long, but the oven roasting will make them easier to digest and they will also taste a lot better. If you need to avoid sodium you can skip adding salt and they will still taste good.

Can acorn squash be refrigerated?

Once it’s cool enough to handle, slice the squash in half, remove its seeds and scoop out the tender flesh. Whether you leave it in shapeless chunks or cut it into cubes, cooked acorn squash can be refrigerated for up to 3 days in an air-tight container.

Does acorn squash need to be cured?

Unlike other winter squash, acorn squash does not need to be cured ( 3 ). Curing is a process that involves exposing winter squash to warm temperatures (80-85°F) for 1-2 weeks. This allows excess moisture to evaporate and helps harden the squash’s skin to increase its shelf life ( 4 ).
