Recipe Notes

  • Feel free to substitute with all yellow squash or all zucchini.
  • Use oil or vegan butter in place of regular butter if dairy-free or vegan.

Meal Prep and Storage

  • To Prep-Ahead: Finely chop the onion and store it separately from the cut squash. Keep uncooked vegetables in an airtight container in the refrigerator for up to 3-4 days.

  • To Store: Keep leftover sautéed squash in an airtight container in the refrigerator for up to 3-4 days.

  • To Freeze: Allow to cool, then transfer to an airtight freezer-safe container, freeze up to 3 months.  

  • To Reheat: While you can always pop it back in the microwave, the best way to reheat this yellow squash and zucchini is to add it to a skillet with a touch of oil or butter. Cook over medium-low heat until heated through.
