Ingredients

For the Foil Packets

1½ lbs (680 g) boneless, skinless chicken breasts or thighs
2 cups fresh pineapple chunks
1 red bell pepper, cut into bite-sized pieces
1 yellow bell pepper, cut into bite-sized pieces
1 small zucchini, sliced
½ small red onion, sliced
2 tablespoons olive oil
½ teaspoon salt
¼ teaspoon black pepper
½ teaspoon garlic powder
½ teaspoon ground ginger

For the Teriyaki Sauce

½ cup low-sodium soy sauce
¼ cup pineapple juice
2 tablespoons honey or brown sugar
1 tablespoon rice vinegar
2 cloves garlic, minced
1 teaspoon freshly grated ginger
1 tablespoon cornstarch
2 tablespoons cold water

For Garnishing

2 green onions, thinly sliced
1 tablespoon sesame seeds
Fresh cilantro, optional
Lime wedges, optional

Directions

1. Prepare the Chicken

Cut the chicken into bite-sized pieces, approximately 1–1½ inches each.

Pat the chicken dry with paper towels.

Place it in a large bowl and season with salt, black pepper, garlic powder, and ground ginger.

Toss well to coat.

2. Make the Teriyaki Sauce

In a small saucepan, combine the soy sauce, pineapple juice, honey or brown sugar, rice vinegar, minced garlic, and fresh ginger.

Bring the mixture to a gentle simmer over medium heat.

In a small bowl, mix the cornstarch with cold water until completely smooth.

Slowly whisk the cornstarch mixture into the simmering sauce.

Cook for approximately 1–2 minutes, stirring constantly, until the sauce thickens slightly.

Remove from the heat and allow it to cool for a few minutes.

3. Prepare the Vegetables

Place the pineapple chunks, bell peppers, zucchini, and red onion in a large bowl.

Add the olive oil and toss gently.

Keep the vegetables and chicken in separate bowls until you’re ready to assemble the packets.

4. Prepare the Foil

Preheat the oven to 425°F (220°C).

Cut four large sheets of heavy-duty aluminum foil, approximately 12 × 18 inches each.

For easier cleanup and extra protection, you can double-layer the foil.

Place the foil sheets on a work surface.

5. Assemble the Packets

Divide the chicken evenly among the four foil sheets.

Add the pineapple and vegetables around and over the chicken.

Drizzle approximately 2–3 tablespoons of teriyaki sauce over each portion.

Don’t add all the sauce at once; reserve some for serving.

6. Seal the Packets

Bring the long sides of the foil together over the chicken and vegetables.

Fold them together several times to create a secure seal.

Fold the short ends inward to completely close the packet.

Leave a little room inside each packet so the steam can circulate.

7. Bake

Place the foil packets on a baking sheet.

Bake for approximately 20–25 minutes, depending on the size of the chicken pieces.

The chicken should reach an internal temperature of 165°F (74°C).

8. Carefully Open the Packets

Remove the packets from the oven and let them rest for 2–3 minutes.

Carefully open them away from your face because hot steam will escape.

Drizzle with additional teriyaki sauce.

9. Garnish and Serve

Sprinkle the chicken and pineapple with sliced green onions and sesame seeds.

Add fresh cilantro or a squeeze of lime if desired.

Serve immediately.

Grilling Instructions

These foil packets are also excellent on the grill.

Preheat your grill to approximately 400–425°F (200–220°C).

Place the sealed packets directly on the grill grates.

Cook for approximately 20–25 minutes, turning the packets carefully halfway through.

Check that the chicken reaches 165°F (74°C) before serving.

For extra browning, carefully open the packets during the final few minutes and place them back on the grill, watching closely.

Air Fryer Method

For smaller individual packets, preheat the air fryer to 375°F (190°C).

Place the foil packets in the basket without overcrowding.

Cook for approximately 15–20 minutes, depending on the size of the chicken pieces.

Check the thickest chicken pieces with a food thermometer to make sure they reach 165°F (74°C).

Tips for the Best Foil Packets

Cut everything evenly: Similar-sized chicken pieces and vegetables cook more consistently.

Use chicken thighs for extra juiciness: Boneless chicken thighs are more forgiving and stay moist during cooking.

Don’t overfill the packets: Crowding can prevent the ingredients from cooking evenly.

Seal the packets well: A tight seal keeps the steam and teriyaki flavors inside.

Be careful when opening: The packets contain extremely hot steam.

Don’t overcook the chicken: Start checking around the 20-minute mark, especially if your chicken pieces are small.

Serving Suggestions

Serve these Teriyaki Chicken and Pineapple Foil Packets with:

Steamed white rice
Jasmine rice
Coconut rice
Fried rice
Quinoa
Noodles
Asian-style cucumber salad
Steamed broccoli

For a complete meal, spoon the flavorful juices from the packet over the rice.

Variations

Spicy Teriyaki Chicken

Add ½ teaspoon crushed red pepper flakes or a drizzle of chili sauce to the teriyaki sauce.

Teriyaki Shrimp & Pineapple

Replace the chicken with peeled and deveined shrimp. Because shrimp cooks quickly, reduce the cooking time and check frequently.

Teriyaki Beef Packets

Use thinly sliced beef instead of chicken. Sirloin or another tender cut works particularly well.

Vegetarian Foil Packets

Replace the chicken with tofu and add extra vegetables such as mushrooms, broccoli, snap peas, and carrots.

Make-Ahead Instructions

You can prepare the chicken, vegetables, and sauce several hours ahead of time.

Store everything separately in the refrigerator until ready to assemble.

For food safety, keep the raw chicken refrigerated and assemble the packets shortly before cooking.

Storage and Reheating

Store leftover cooked chicken and vegetables in an airtight container in the refrigerator for up to 3–4 days.

Reheat gently in the oven, microwave, or air fryer until thoroughly hot.

Keep leftover sauce refrigerated separately if possible.

Frequently Asked Questions

Can I use canned pineapple?

Yes. Drain it thoroughly before using. You can reserve some of the juice for the teriyaki sauce.

Can I use chicken thighs?

Absolutely. Boneless, skinless chicken thighs are an excellent choice and tend to remain especially juicy.

Can I prepare the packets the night before?

It’s better to prepare the components separately and assemble them shortly before cooking, especially because raw chicken and vegetables can release moisture while sitting.

Can I use bottled teriyaki sauce?

Yes. A good-quality prepared teriyaki sauce can save time. Use approximately ¾–1 cup, depending on how saucy you like the packets.
