Ingredients

For the chicken and vegetables

1½ lb (680 g) boneless, skinless chicken breasts or thighs
2 cups fresh pineapple chunks
1 red bell pepper, cut into bite-sized pieces

1 small red onion, cut into chunks
2 tbsp olive oil
½ tsp salt
½ tsp black pepper
½ tsp garlic powder
½ tsp ground ginger
2 green onions, sliced
1 tbsp sesame seeds, for garnish

For the homemade teriyaki sauce

½ cup (120 ml) low-sodium soy sauce
¼ cup (60 ml) pineapple juice
2 tbsp honey
2 tbsp brown sugar
1 tbsp rice vinegar
1 tbsp sesame oil
2 cloves garlic, finely minced
1 tsp freshly grated ginger
1 tbsp cornstarch
2 tbsp cold water

Cooked white or brown rice
Extra pineapple chunks
Sliced green onions
Sesame seeds
Lime wedges, optional
Sriracha or chili sauce, optional

Instructions

1. Prepare the chicken

Pat the chicken dry with paper towels.

Cut the chicken into fairly even pieces, approximately 1½-inch chunks.

Keeping the pieces similar in size is important because it allows them to cook at roughly the same rate.

Chicken thighs are particularly good for foil packets because they remain juicy and flavorful even if they cook slightly longer than expected. Chicken breast works beautifully as well but should not be overcooked.

Place the chicken in a large bowl.

Add the olive oil, salt, black pepper, garlic powder, and ground ginger.

Toss until evenly coated.

Set aside while you prepare the sauce and vegetables.

2. Make the teriyaki sauce

In a small saucepan, combine:

Soy sauce
Pineapple juice
Honey
Brown sugar
Rice vinegar
Sesame oil
Garlic
Fresh ginger

Whisk everything together.

Place the saucepan over medium heat and bring the mixture to a gentle simmer.

In a small bowl, mix the cornstarch with the 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 and becomes glossy.

Remove from the heat.

The sauce should be thick enough to coat the back of a spoon but still pourable.

Allow it to cool for a few minutes.

3. Prepare the vegetables

Cut the bell peppers, zucchini, and red onion into pieces roughly similar in size to the chicken.

Place them in a large bowl.

Add the pineapple chunks.

Fresh pineapple gives the best flavor, but canned pineapple can absolutely be used. If using canned pineapple, drain it thoroughly and reserve some of the juice for the sauce.

4. Preheat the oven

Preheat your oven to 425°F (220°C).

You’ll need four large sheets of heavy-duty aluminum foil.

For easier handling, you can place each sheet of foil on top of a sheet of parchment paper.

The parchment is optional but helps prevent the sauce from sticking directly to the foil.

5. Assemble the packets

Lay four large sheets of foil on your work surface.

Divide the chicken evenly between the four pieces of foil.

Arrange the pineapple and vegetables around the chicken.

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

Toss the ingredients gently with your hands or a spoon to coat them.

Don’t add every bit of sauce at this point. Save some for serving.

6. Seal the packets

Bring the two long sides of the foil together over the food.

Fold them down several times to create a tight seal.

Then fold the short ends inward.

You want each packet securely sealed so that steam stays inside.

However, don’t wrap the packets so tightly that the ingredients are completely compressed. Leave a little room inside for steam to circulate.

7. Bake

Place the foil packets on a large baking sheet.

Transfer them to the preheated oven.

Bake for approximately 25–30 minutes.

The exact cooking time depends on the size of your chicken pieces.

The chicken is safely cooked when the thickest piece reaches 165°F (74°C).

If you’re using larger chunks of chicken, they may require a few additional minutes.

8. Carefully open the packets

Remove the packets from the oven.

Allow them to sit for about 5 minutes.

Be very careful when opening them.

The packets will contain extremely hot steam, which can cause burns.

Open the packets away from your face and hands.

9. Add the finishing sauce

Drizzle the remaining teriyaki sauce over the chicken and vegetables.

Sprinkle with sliced green onions and sesame seeds.

For a little heat, add a small drizzle of sriracha or your favorite chili sauce.

A squeeze of fresh lime juice is also excellent and helps balance the sweetness of the teriyaki and pineapple.

How to Serve

These packets are excellent served directly over rice.

Spoon the chicken, pineapple, and vegetables over:

Steamed white rice
Jasmine rice
Brown rice
Coconut rice
Cauliflower rice
Quinoa

For a complete tropical-inspired dinner, serve with a simple cucumber salad or steamed edamame.

Tips for Perfect Foil Packets

Cut the chicken evenly

The most important thing is consistency.

If some chicken pieces are tiny and others are very large, the small pieces can become overcooked while you’re waiting for the larger pieces to finish.

Aim for pieces around 1½ inches.

Don’t use too much sauce before baking

It can be tempting to pour all of the teriyaki sauce over the packets.

Don’t.

The pineapple and vegetables will release some moisture as they cook, so adding too much sauce can make the packets watery.

Using some sauce during cooking and saving the rest for finishing gives you a much better consistency.

Use heavy-duty foil

Regular foil can tear more easily when you’re assembling and moving the packets.

If you only have regular foil, use two layers.

Don’t skip the baking sheet

Even if the packets are tightly sealed, placing them on a baking sheet makes them much easier to transfer into and out of the oven.

It also catches any sauce that happens to leak.

Grilled Version

These foil packets are fantastic 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 once halfway through if desired.

Check the chicken with an instant-read thermometer to ensure it reaches 165°F (74°C).

For a little extra caramelization, carefully open the packets during the final few minutes and let the ingredients cook uncovered.

Be extremely careful when opening them because hot steam will escape.

Vegetable Variations

You can easily customize the packets depending on what you have available.

Good additions include:

Broccoli florets
Sugar snap peas
Mushrooms
Carrots
Snow peas
Baby corn
Asparagus
Green bell peppers

If using dense vegetables such as carrots, cut them fairly thin so they have enough time to cook.

Spicy Teriyaki Version

For a sweet-and-spicy version, add one or more of the following to the sauce:

1 tsp sriracha
½ tsp crushed red pepper flakes
1 tsp chili garlic sauce
½ tsp cayenne pepper

You can also add thinly sliced jalapeño to the packets.

Coconut Teriyaki Version

Replace ¼ cup of the pineapple juice with ¼ cup coconut milk.

Add a little extra ginger and serve the finished chicken over coconut rice.

The creamy coconut flavor works especially well with pineapple.

Make-Ahead Instructions

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

Keep everything refrigerated separately.

For food-safety reasons, don’t leave assembled raw chicken packets sitting at room temperature.

When you’re ready to cook, assemble the packets and transfer them directly to the oven.

Storage and Reheating

Remove the chicken and vegetables from the foil and transfer leftovers to an airtight container.

Refrigerate within 2 hours of cooking.

Leftovers are best consumed within 3–4 days.

Reheat gently in the microwave or in a skillet over medium-low heat.

Add a small splash of water or extra teriyaki sauce if the chicken seems dry.

Easy Dinner Combination

For a particularly satisfying plate, serve each packet with:

Teriyaki chicken + caramelized pineapple + peppers and zucchini + jasmine rice + sesame seeds + green onions + lime.

The sweet pineapple, savory soy sauce, tender chicken, and slightly smoky vegetables make this a flavorful dinner with very little cleanup.
