These Mediterranean Baked Fish Boats are filled with flaky white fish, zucchini, tomatoes, red onion, bell pepper, lemon, and herbs. Everything cooks together in parchment paper, which keeps the fish moist and catches all the tomato and lemon juices underneath.

I make fish often because it cooks quickly and doesn’t need a complicated sauce to taste good. My pan-seared halibut is perfect when I want something simple, my fish tacos are always a fun family dinner, and this butter lemon tilapia is one of my favorite weeknight recipes.

These parchment fish boats are just as easy, but the fish and vegetables cook together in individual portions. I love serving them directly in the parchment because every boat holds onto the lemony cooking juices, and there is very little cleanup afterward.
This is the kind of healthy 30-minute dinner I love making when I want something filling without feeling heavy. Each parchment boat is already a complete meal, and serving the fish right in the paper makes even a simple weeknight dinner feel a little more special.
Why You’ll Love These Mediterranean Fish Boats
The fish stays incredibly juicy – Baking it over the vegetables in parchment helps hold in moisture, so the fillets come out tender instead of dry.
A complete dinner in every boat – Each portion includes fish and plenty of colorful vegetables, so you don’t need to prepare several separate dishes.
Ready in about 30 minutes: The vegetables and fish cook together, so there are no complicated extra steps.
Naturally low carb and gluten-free: There is no breading or flour, just fish, vegetables, seasonings, lemon, and olive oil.
Less cleanup: The parchment holds the vegetables and juices, leaving the sheet pan much easier to clean.
Ingredients You’ll Need
White Fish Fillets – Cod, haddock, halibut, sea bass, or tilapia all work well. I prefer firm fillets that are similar in size so they finish baking at the same time.
Zucchini – Slice it very thinly or use a vegetable peeler to make ribbons. It creates a soft bed for the fish and absorbs all the lemony juices as it cooks.
Red Onion – Thin slices add a little sweetness and a sharper flavor that works especially well with the tomatoes and lemon.
Cherry Tomatoes – Once baked, they become soft and juicy, creating a light sauce at the bottom of each parchment boat.
Red Bell Pepper – Bell pepper adds natural sweetness, color, and a little texture. Cut it into thin strips so it cooks quickly.
Lemon – You’ll use both slices and fresh juice for plenty of bright citrus flavor.
Olive Oil – A drizzle over the vegetables and fish keeps everything moist and brings the Mediterranean flavors together.
Oregano and Paprika – Oregano gives the fish that familiar Mediterranean flavor, while paprika adds warmth and a little color.
Garlic Powder – Garlic powder adds plenty of savory flavor and coats the fish more evenly than fresh garlic.
Fresh Parsley or Dill – Both work beautifully here. Parsley is mild and fresh, while dill gives the fish a slightly brighter, more distinctive flavor.

How to Make Mediterranean Baked Fish in Parchment
These parchment fish boats are simple to assemble, and each one becomes an individual serving filled with tender fish, colorful vegetables, and plenty of bright Mediterranean flavor.
Shape the Parchment Boats
Preheat the oven to 400°F or 200°C.
Cut three large sheets of parchment paper. Fold each sheet into an accordion pattern, then tie both ends with kitchen twine. If you don’t have kitchen twine, simply twist the ends tightly instead.

Gently open the centers to form boat shapes, then place the parchment boats on a large sheet pan.

Add the Vegetables
Divide the zucchini, red onion, cherry tomatoes, and sliced bell pepper evenly among the three parchment boats.

Drizzle the vegetables with 1 tablespoon of olive oil and season lightly with salt and black pepper.
Add and Season the Fish
Place one white fish fillet over the vegetables in each boat.

Season the fish evenly with the oregano, paprika, garlic powder, salt, and black pepper. Drizzle with the remaining tablespoon of olive oil.
Add the Lemon and Herbs
Cut half of the lemon into thin slices and place one or two slices over each fillet. Squeeze the juice from the remaining half over the fish.

Bake the Fish Boats
Bake for 15 to 20 minutes, depending on the thickness of the fillets. The fish is ready when it flakes easily with a fork and reaches an internal temperature of 145°F or 63°C.

Finish and Serve
Top the baked fish with fresh herbs, if desired.

Serve immediately in the parchment boats with all the tender vegetables and lemony juices spooned over the fish.
Tips for Moist and Flaky Baked Fish
Choose fillets with a similar thickness. This helps all portions cook evenly and prevents one piece from drying out while another is still undercooked.
Pat the fish dry first. Removing excess moisture helps the olive oil and seasonings stick to the fillets.
Don’t overcrowd the parchment boats. Leave enough room around the fish so the hot air can circulate and the vegetables cook evenly.
Use wide sheets of parchment. The sides need to be high enough to hold the vegetables and juices without spilling onto the baking sheet.
Check thinner fillets early. Delicate fillets may be ready after 12 to 15 minutes, so begin checking before the full cooking time has passed.

Mediterranean Fish Boat Variations
You can easily change these Mediterranean fish boats depending on what you have in the refrigerator. Try adding sliced olives, baby spinach, artichoke hearts, asparagus, or thinly sliced yellow squash.
For a little heat, sprinkle the fish with red pepper flakes before baking. A small pat of butter placed over each fillet also adds richness, while olives give the boats a saltier, brinier flavor.
What to Serve with Mediterranean Baked Fish
Each parchment boat already includes fish and vegetables, so it can easily be served as a complete light meal.
For something more filling, pair the fish with cauliflower rice, roasted potatoes, quinoa, rice, or a simple lemony salad. Crusty bread is also delicious for soaking up the garlicky tomato and lemon juices collected at the bottom of the parchment.

How to Store and Reheat Baked Fish
Fridge: Transfer the fish and vegetables from the parchment into an airtight container. Refrigerate for up to 2 days.
Reheating: Reheat leftovers gently until the center reaches 165°F (74°C). Avoid heating them longer than necessary because white fish dries out quickly.
You can also reheat individual portions in the microwave using short intervals. Avoid overheating, as white fish can become dry quickly.
Freezer: I don’t recommend freezing the assembled dish because the cooked zucchini and tomatoes may become watery after thawing.

Frequently Asked Questions
What is the best fish for this recipe?
Cod, haddock, halibut, sea bass, and tilapia are all good choices. Use a mild white fish that is firm enough to sit over the vegetables without falling apart.
Can I use frozen fish?
Yes, but thaw the fillets completely and pat them dry before seasoning. Excess water from partially frozen fish can make the vegetables and parchment boats too watery.
Do I need to close the parchment completely?
No. These are open parchment boats rather than fully sealed parchment packets. Folding the sides upward helps hold in the vegetables and juices while allowing the top of the fish to roast lightly.
Can I prepare the boats ahead of time?
You can slice the vegetables and mix the seasonings earlier in the day. For the best texture, assemble the parchment boats shortly before baking so the fish and vegetables don’t sit in the salt and lemon juice for too long.

Notes
- Cod, haddock, halibut, sea bass, tilapia, or another firm white fish works well.
- Slice the zucchini very thinly so it cooks at the same rate as the fish.
- Do not overfill the boats. Too many vegetables can release excess water and prevent the vegetables at the bottom from cooking properly.
- For extra flavor, add sliced olives, baby spinach, artichoke hearts, red pepper flakes, or a small pat of butter.
- Cooking time may vary depending on the type and thickness of the fish.
- Store leftovers in an airtight container in the refrigerator for up to 2 days.
