How to Purchase and Store Acorn Squash

When buying acorn squash, choose one that feels heavy for its size. The skin should be firm and dull, not shiny, with no dents, soft spots, or deep cuts. A dry stem is a good sign it was picked mature.

Store acorn squash in a cool, dark place with good air flow. Do not wash it before storing. Extra moisture can cause it to spoil faster. When kept properly, acorn squash can last 2 to 3 months.

Substitutions for Pumpkin Pie Spice

If you don't have pumpkin pie spice, you can make a simple swap with spices you already have.

Cinnamon and nutmeg: Use 2 parts cinnamon to 1 part nutmeg. This gives you that classic warm flavor.
Cinnamon and ginger: Mix equal parts for a slightly brighter, spiced finish.
Apple pie spice: A ready-made blend that works the same way in this recipe.
Chai spice blend: Usually includes cinnamon, cardamom, and cloves. Adds a deeper, more layered flavor.
Garam masala: Contains cinnamon, nutmeg, and cardamom. Use lightly since it's more savory.
Ground cardamom: Just a pinch adds a floral note. A little goes a long way.

Garnishes for Squash Dishes

Acorn squash has plenty of flavor on its own. A simple finish is often all it needs. If you're serving it at the table and want to dress it up, try one of these:

Fresh herbs such as chopped parsley, thyme, or sage
A spoonful of sautéed garlic and ginger cooked in butter
A light drizzle of honey
Roasted pumpkin seeds, chopped walnuts, or pecans
Pomegranate arils with a little fresh orange zest

Storage and Reheating

Allow the roasted acorn squash to cool completely before storing. Place it in an airtight container and refrigerate for up to 2 to 3 days.

Freezing

Roasted acorn squash can be frozen. Let it cool completely, then wrap tightly or place in a freezer-safe container. Freeze for up to 3 months.

For best results, thaw overnight in the refrigerator and reheat in the oven. The texture may be slightly softer after freezing, but the flavor holds up well.
