How to Store or Freeze This Dish
Allow the grilled butternut squash to cool completely before storing. This prevents condensation, which can make the squash soggy.
Place the cooled squash slices in an airtight container. If you have multiple layers, separate them with parchment paper to avoid sticking.
Store the container in the refrigerator. The grilled butternut squash will stay fresh for up to 3-4 days.
For longer storage, consider freezing. Lay the squash slices in a single layer on a baking sheet lined with parchment paper. Freeze until solid, about 1-2 hours.
Once frozen, transfer the squash slices to a freezer-safe bag or container. Label with the date to keep track of freshness.
When ready to use, thaw the grilled butternut squash in the refrigerator overnight. Reheat in the oven at 350°F (175°C) for about 10-15 minutes, or until warmed through.
Alternatively, you can reheat the squash directly from frozen. Place the slices on a baking sheet and bake at 350°F (175°C) for 20-25 minutes, or until heated thoroughly.
To maintain the best texture and flavor, avoid microwaving the squash, as it can become mushy.
Enjoy your grilled butternut squash as a side dish, in salads, or as a topping for soups and stews.
How to Reheat Leftovers
