Tip for scraping out zucchini flesh. Use a sharp knife to lightly score the zucchini to outline the area you want to scoop out being very careful not to cut through. You just want an outline. Use the tip of a spoon to scrape the flesh out and on to a cutting board.
Storage and Reheating
Refrigerate: Transfer leftover zucchini boats to an airtight container and refrigerate for up to 4 days.
Reheat: Reheat individual servings in the microwave until warmed through, or cover and reheat in a 350°F oven until hot.
Freeze: You can freeze the cooked zucchini boats, but keep in mind that the zucchini will have a softer texture after thawing. Transfer to a freezer-safe container and freeze for up to 2 to 3 months. Thaw overnight in the refrigerator before reheating.
