Herbs: Dried basil, parsley, and Italian seasoning create a fragrant blend that complements the zucchini beautifully.

How to Make Air Fryer Zucchini Foil Packets

Step 1: Slice the Zucchini

Wash and dry the zucchini, then trim off both ends. Cut each zucchini into uniform ¼-inch rounds so the slices cook evenly and become tender without turning mushy.

Step 2: Season the Zucchini

Add the sliced zucchini to a large mixing bowl. Drizzle with olive oil and melted butter, then add the minced garlic, lemon juice, lemon zest, dried basil, parsley, Italian seasoning, salt, and black pepper.

Toss everything together until the zucchini is evenly coated. Stir in most of the grated Parmesan, reserving a little to sprinkle over the packets before cooking.

Step 3: Prepare the Foil Packets

Cut four 12-inch sheets of heavy-duty aluminum foil. Divide the seasoned zucchini evenly among the sheets, arranging the slices in the center of each piece. Sprinkle the reserved Parmesan over the zucchini for an extra cheesy finish.

Step 4: Seal the Packets

Bring the long edges of each foil sheet together over the zucchini and fold them down twice to create a secure seal. Fold and crimp the shorter ends to close the packets, leaving a little space inside for steam to circulate.

Step 5: Air Fry Until Tender

Preheat your air fryer to 350°F for 3–5 minutes, following your appliance’s instructions. Arrange the foil packets in a single layer in the basket, seam side up, making sure they fit securely.

Air-fry for approximately 15–25 minutes, checking the zucchini after 15 minutes. Cooking time will vary depending on the thickness of the slices, the size of the packets, and your air fryer. The zucchini should be tender but still retain a little bite.

Step 6: Open and Serve

Carefully remove the packets from the air fryer and let them rest for about a minute. Open the foil away from your face and hands because the escaping steam will be very hot.

Finish with an extra sprinkle of Parmesan cheese and fresh parsley, if desired. Serve the zucchini directly from the opened foil packets or transfer it to a serving plate while warm.

Tips for the Best Zucchini Foil Packets

Cut Uniform Slices: Aim for ¼-inch rounds so the zucchini cooks evenly. Thinner slices will cook faster and may become soft more quickly.
Choose Heavy-Duty Foil: Sturdy foil is less likely to tear when folding or lifting the packets, helping keep the buttery juices and melted cheese inside.
Avoid Overfilling: Divide the zucchini evenly among the packets rather than creating a tall pile. This helps the slices cook more consistently.
Keep the Seams Facing Up: Position the packets seam side up to help contain the buttery juices and cheese as the zucchini cooks.
Check for Doneness Early: Air fryers can vary in temperature and performance, so check a slice with a fork after 15 minutes and continue cooking as needed.
Use Foil Safely: Follow your air fryer manufacturer’s instructions for aluminum foil. Keep the packets secured by the food, arrange them away from the heating element, and never allow loose foil to blow toward it.

Variations

Add More Vegetables: Mix in thinly sliced yellow squash, bell peppers, red onion, or cherry tomatoes for extra color and flavor. Cut the vegetables into similar-sized pieces for more even cooking.
Make It Spicy: Sprinkle in a pinch of red pepper flakes before sealing the packets for a little heat.
Try Pesto: Replace some of the dried herbs with basil pesto for a fresh, savory twist.
Make It Extra Cheesy: Add shredded mozzarella along with the Parmesan for a richer, gooier finish.
Use Ranch Seasoning: Replace the Italian herbs with dry ranch seasoning for a tangy, savory variation.

Zucchini Foil Packets in the Oven or on the Grill

Don’t have an air fryer? You can prepare these Parmesan zucchini foil packets using an oven or an outdoor grill. The following cooking times are starting points, so check the zucchini for tenderness before serving.

Oven: Arrange the sealed packets on a baking sheet and bake at 400°F for approximately 20–25 minutes, or until the zucchini reaches your preferred tenderness.
Grill or Blackstone: Cook the packets over medium-high heat for approximately 10–15 minutes, checking for doneness. Keep the packets seam side up and use heat-resistant utensils to handle them safely.

Serving Suggestions

Grilled Chicken: Pair the zucchini with grilled or roasted chicken for a simple, balanced weeknight dinner.
Steak or Pork Chops: Serve alongside grilled steak, baked pork chops, or pan-seared meat for a hearty meal.
Salmon or White Fish: Complement baked salmon, cod, or tilapia with this flavorful vegetable side.
Pasta Dishes: Enjoy the zucchini with spaghetti, fettuccine Alfredo, or your favorite tomato-based pasta.
Rice or Quinoa Bowls: Spoon the cooked zucchini over rice or quinoa and add your favorite protein for a satisfying grain bowl.
Summer Cookouts: Include these foil packets alongside burgers, grilled meats, and other cookout favorites.
Vegetarian Meals: Serve with roasted potatoes, crusty bread, or a hearty grain salad for a delicious meat-free dinner.

Make-Ahead, Storing, and Reheating

Make Ahead: Prepare and seal the foil packets up to 24 hours in advance. Store them in the refrigerator until you’re ready to cook. If cooking directly from cold, allow extra time and check the zucchini for doneness.

Refrigerator: Transfer leftover cooked zucchini to an airtight container and refrigerate within two hours of cooking. Enjoy within 3–4 days for the best quality.

Reheating: Place the leftovers in a fresh, securely arranged foil packet and air-fry at 350°F for approximately 3–5 minutes, checking frequently until heated through. Alternatively, microwave the zucchini in a microwave-safe dish until warm.

Freezing: Freezing is not recommended because zucchini contains a high amount of moisture. After thawing, the slices can become watery and soft, losing much of their original texture.
