- 2 white fish fillets
- 12 large shrimp, peeled

The blended sauce is flexible—add a pinch of chili flakes for mild heat or a garlic clove for extra depth without changing the overall method.

Step-by-step instructions
Follow these clear steps to build and bake the perfect seafood foil packet.
Step 1: Sauté the vegetables
Heat olive oil in a skillet over medium heat. Add sliced onion, tomatoes, carrot pieces, and any mushrooms, cooking until softened and fragrant.
Step 2: Blend the sauce base
Transfer the sautéed vegetables to a blender. Puree until smooth and slightly thick, creating a vibrant orange-red sauce for coating.
Step 3: Prepare the foil base
Lay a large sheet of foil on a baking tray. Spread shredded cabbage and onion in the center as a bed for the fish.
Step 4: Add and coat the fish
Place the white fish fillet on the vegetable bed. Brush generously with the blended vegetable sauce so it is fully coated.
Step 5: Top with shrimp and carrots
Arrange peeled shrimp and julienned carrot sticks over the sauced fish. Brush more sauce across the shrimp for even flavor.
Step 6: Finish with greens and lemon
Scatter broccoli florets around the seafood. Squeeze fresh lemon juice over everything and sprinkle cilantro leaves on top.
Step 7: Seal the foil packet
Fold the foil edges tightly to form a sealed packet, leaving a little space inside for steam. Place the packet on a baking sheet.
Step 8: Bake until perfectly cooked
Bake at 400°F for 18–22 minutes until the fish flakes easily and shrimp turn pink and opaque. Open carefully to release steam.
Tips & common mistakes
A few simple habits guarantee moist seafood and bright flavor every time.
- Pat shrimp and fish completely dry before saucing
- Do not overfill the packet or steam cannot circulate
- Seal edges tightly so juices stay locked inside
- Check doneness early to avoid overcooking shrimp

Frequently asked questions
These answers help you get the best results with this easy foil packet.
Can I make the packets ahead of time?
Yes, assemble them up to four hours ahead and refrigerate. Bake straight from the fridge, adding two extra minutes if needed for even cooking.
What fish works best in this recipe?
Mild white fish such as cod, tilapia, or halibut holds up well. Thicker fillets stay moist while thinner ones cook a bit faster inside the packet.
How do I know when the seafood is done?
The fish should flake easily with a fork and shrimp turn fully pink and opaque. Avoid overbaking so the texture stays tender and juicy.
Can I freeze leftover packets?
Cooked leftovers keep two days in the fridge. Freezing is not ideal because the vegetables can become watery after thawing and reheating.
