Ingredients for Balsamic Grilled Zucchini
Zucchini: Fresh, medium-sized zucchini, sliced lengthwise for even grilling.
Balsamic vinegar: Provides a tangy, slightly sweet flavor that complements the zucchini.
Olive oil: Helps to coat the zucchini and adds a rich, smooth texture.
Garlic powder: Adds a subtle garlic flavor without overpowering the dish.
Dried oregano: Brings an earthy, herbal note to the marinade.
Salt: Enhances the overall flavor of the zucchini.
Pepper: Adds a touch of heat and balances the flavors.
Technique Tip for This Recipe
To enhance the flavor of your zucchini, try marinating the slices in the balsamic vinegar mixture for at least 15-20 minutes before grilling. This allows the zucchini to absorb more of the balsamic and herb flavors, resulting in a more robust taste. Additionally, make sure your grill is properly preheated to medium-high heat to achieve those perfect grill marks and a tender texture.

How To Store or Freeze This Dish
Allow the zucchini to cool completely before storing. This helps prevent condensation, which can make the zucchini soggy.
Place the cooled zucchini slices in an airtight container. If stacking the slices, separate each layer with parchment paper to avoid sticking.
Store the container in the refrigerator. The balsamic grilled zucchini will stay fresh for up to 3-4 days.
For freezing, arrange the cooled zucchini slices in a single layer on a baking sheet lined with parchment paper. This prevents them from sticking together.
Place the baking sheet in the freezer for about 1-2 hours, or until the zucchini slices are frozen solid.
Transfer the frozen zucchini slices to a freezer-safe bag or container. Label with the date to keep track of freshness.
When ready to use, thaw the zucchini in the refrigerator overnight. Reheat in a skillet over medium heat or in the oven at 350°F (175°C) until warmed through.
Avoid microwaving the zucchini as it can make them mushy.
