Yes, the skin of acorn squash is edible, and many people eat it cooked. However, whether you should eat it depends on texture and personal preference. Key points

• Edibility: Acorn squash skin is technically edible and contains fiber and nutrients. Most guidelines agree the skin can be consumed when the squash is cooked until tender.

• Texture and palatability: Some skins become tender and pleasant to eat after roasting or baking, while others with tougher skins may remain chewy. If you don’t enjoy the texture, you can remove the skin after cooking.

• Preparation tips: Scrub the squash well before cooking. Cooking methods like roasting, steaming, or baking help soften the skin. If you choose to eat it, ensure the squash is properly cooked to a tender consistency.

• Varietal differences: Acorn squash varieties tend to have relatively tender skins when fully cooked, compared with varieties known for very tough skins. If in doubt, start with cooking until flesh is tender and test texture.

Practical guidance

• If you’re roasting: scrub, halve or slice the squash, scoop seeds, rub with a little oil, and roast until the flesh and skin are tender.
• If you’re steaming or baking: proceed similarly; check for doneness by piercing the flesh and skin with a fork.
• If you’re unsure about texture: you can peel after cooking, though many find the skin edible and convenient to eat as part of the dish.

Bottom line: You can eat acorn squash skin, but whether you want to depends on how tender the skin becomes during cooking and your personal texture preference.
