Nut Information
This recipe is naturally nut-free when prepared with the ingredients listed.
Sesame seeds are NOT tree nuts, but sesame is a separate allergen and can cause serious allergic reactions.
Sesame oil and sesame seeds can be omitted if you need a sesame-free recipe.
Soy sauce contains soy, which is also a common allergen.
For a nut-free and sesame-free version, use olive oil instead of sesame oil and omit sesame seeds.
Always check packaged sauces for allergy statements and possible cross-contact if cooking for someone with allergies.
Instructions
1. Prepare the Teriyaki Sauce
In a small saucepan, combine soy sauce, honey, rice vinegar, sesame oil, ginger, garlic, and red pepper flakes.
Whisk together cornstarch and water in a small bowl until smooth. Add this slurry to the saucepan.
Cook over medium heat for 2–4 minutes, stirring frequently, until the sauce thickens slightly.
Remove from heat and let it cool for a few minutes.
2. Prepare the Chicken
Place the chicken pieces in a large bowl.
Add about ⅓ of the teriyaki sauce and toss well to coat.
For extra flavor, let the chicken marinate for 15–30 minutes in the refrigerator.
3. Prepare the Foil
Preheat the oven to 425°F (220°C).
Cut 4 large sheets of heavy-duty aluminum foil.
For easier handling, you can place a second sheet underneath each packet.
4. Assemble the Packets
Divide the chicken evenly between the foil sheets.
Add pineapple, bell peppers, zucchini, and red onion.
Drizzle each packet with a little olive oil and season with salt, pepper, and garlic powder.
Spoon some of the remaining teriyaki sauce over each portion.
5. Seal the Packets
Bring the long sides of the foil together over the food and fold them tightly.
Fold the short ends inward to create completely sealed packets.
Leave a little room inside each packet for steam to circulate.
6. Bake
Place packets on a large baking sheet.
Bake for 20–25 minutes, depending on the size of the chicken pieces.
Chicken should reach an internal temperature of 165°F (74°C).
7. Open Carefully
Let packets rest for about 3–5 minutes.
Carefully open them because the steam inside will be very hot.
Garnish with green onions, sesame seeds, and cilantro.
Serve immediately!
Grilling Method
Preheat grill to medium-high heat, around 400–425°F (200–220°C).
Place sealed foil packets directly on the grill.
Cook for approximately 18–25 minutes, turning once halfway through.
Check that the chicken reaches 165°F (74°C).
Carefully open and garnish.
Air Fryer Method
For smaller individual packets:
Preheat air fryer to 375°F (190°C).
Prepare smaller foil packets.
Place them carefully in the basket without overcrowding.
Cook for 15–20 minutes.
Check the chicken reaches 165°F (74°C) before serving.
Helpful Tips
Cut the chicken into similar-sized pieces so everything cooks evenly.
Fresh pineapple gives the best flavor, but canned pineapple can also be used. Drain it very well.
Don’t overfill the foil packets.
Heavy-duty foil is best because it is less likely to tear.
Add extra red pepper flakes if you like a spicy-sweet teriyaki flavor.
For a lower-sugar version, replace honey with a suitable sugar-free sweetener and use a low-sugar teriyaki-style sauce.
If using chicken thighs, cooking time may vary slightly.
Vegetable Variations
You can also add:
Broccoli florets
Mushrooms
Snow peas
Carrots
Green beans
Asparagus
What to Serve With It
These packets are delicious with:
Steamed jasmine rice
Brown rice
Cauliflower rice
Quinoa
Asian cucumber salad
Steamed broccoli
For a low-carb meal, cauliflower rice + extra vegetables works especially well.
Storage
Transfer leftovers to an airtight container and refrigerate within 2 hours.
Refrigerator: Up to 3–4 days
Freezer: Up to 2 months
Reheat until the chicken reaches a safe serving temperature.
Q&A
Q: Can I use chicken thighs instead of chicken breast?
Yes. Boneless, skinless chicken thighs are especially juicy and work very well in foil packets.
Q: Can I use canned pineapple?
Yes. Choose pineapple packed in juice rather than heavy syrup and drain it thoroughly.
Q: Can I make this recipe ahead of time?
You can prepare the vegetables, chicken, and sauce ahead of time. Assemble the packets shortly before cooking for the best texture.
Q: Can I make these packets without soy sauce?
Yes. Use coconut aminos as an alternative, keeping in mind that the flavor will be somewhat sweeter.
Q: Are these packets gluten-free?
They can be. Use certified gluten-free tamari or gluten-free soy sauce and verify all packaged ingredients.
Q: Are these packets dairy-free?
Yes, the recipe as written is dairy-free.
Q: Are they nut-free?
Yes, the basic recipe contains no tree nuts or peanuts. However, sesame is included as an optional ingredient and should be avoided if sesame is an allergy concern.
Q: Can I make them spicy?
Absolutely. Add red pepper flakes, sriracha, or a little chili-garlic sauce to the teriyaki mixture.
Q: Why did my vegetables become too soft?
Cut vegetables into slightly larger pieces and avoid overcooking the packets. Zucchini and pineapple release moisture during cooking, so keeping the packet sealed but not overfilled helps.
Q: Can I serve these with rice inside the foil packet?
It’s better to serve them over separately cooked rice. Raw rice requires substantially more liquid and cooking time than the chicken and vegetables.
