Coastal Garden Haddock Pouches on the Grill
When summer rolls around, I find myself looking for easy dinners that don’t heat up the kitchen. That’s exactly why I love these Coastal Garden Haddock Pouches. Everything cooks together in one foil packet right on the grill. As a bonus, cleanup is practically nonexistent.
This recipe came together one evening when I had fresh zucchini, cherry tomatoes, onions, and baby potatoes that needed to be used. Since haddock is always a favorite around our house, I decided to combine everything into a foil pouch and season it with plenty of Old Bay, lemon, and garlic. The result was a light yet satisfying meal packed with fresh summer flavor.
What I love most about these Coastal Garden Haddock Pouches is how the vegetables create their own sauce as they cook. The cherry tomatoes burst, the onions soften, and the lemon butter mingles with the Old Bay seasoning. Meanwhile, the haddock stays tender and flaky. Furthermore, the green olives add just the right amount of salty, coastal flavor that makes this recipe feel a little special.

Ingredients for Coastal Garden Haddock Pouches
For the Haddock Pouches
- 4 haddock fillets (about 5–6 ounces each)
- 1 pound red baby potatoes, halved
- 1 medium zucchini, sliced into half moons
- 1 cup cherry tomatoes
- 1 medium sweet onion, sliced
- 1/2 cup sliced green olives
- 4 tablespoons butter
- 2 cloves garlic, minced
- 1 lemon, sliced
- 2 tablespoons olive oil
- 2 teaspoons Old Bay seasoning
- 1 teaspoon kosher salt
- 1/2 teaspoon black pepper
- 2 tablespoons fresh parsley, chopped
- Feta Cheese (optional)

How to Make Coastal Garden Haddock Pouches
Step 1: Prepare the Potatoes
Bring a pot of water to a boil. Cook the baby potatoes for about 5 to 7 minutes. Drain well and allow them to cool slightly.
Step 2: Assemble the Pouches
Lay out four large sheets of heavy-duty foil.
Divide the potatoes, zucchini, cherry tomatoes, onions, and green olives evenly among the foil sheets.
Drizzle the vegetables with olive oil and season lightly with salt and pepper.
Place one haddock fillet on top of each vegetable pile.
Step 3: Add the Seasonings
Top each fillet with minced garlic, Old Bay seasoning, a tablespoon of butter, and a few lemon slices.
Step 4: Seal the Pouches
Fold and seal the foil packets tightly. Leave a little room inside each pouch for steam to circulate.
Step 5: Grill
Place the pouches on a preheated grill set to medium heat, approximately 375°F.
Cook for 15 to 18 minutes, or until the haddock flakes easily with a fork and the vegetables are tender.
Step 6: Finish and Serve
Carefully open the pouches.
Sprinkle with fresh parsley and feta cheese, serve immediately with extra lemon wedges if desired.

Nettie’s Kitchen Tip
I like using two sheets of foil for each pouch. First, I place one sheet lengthwise and then another crosswise. After filling the pouch, I fold and seal the first layer before rotating and sealing the second layer. This double-wrap method helps keep all those flavorful juices inside the packet and prevents leaks on the grill.
What to Serve with Coastal Garden Haddock Pouches
Since the potatoes and vegetables cook right in the packet, this recipe can easily stand on its own. However, if you’re feeding a crowd, try serving it with:
Frequently Asked Questions
Can I use frozen haddock?
Yes. Just thaw the haddock completely and pat it dry before assembling the foil packets.
Can I make these pouches in the oven?
Absolutely. Bake the sealed pouches at 400°F for about 18 to 22 minutes.
Can I prepare the pouches ahead of time?
Yes. Assemble the packets up to 8 hours in advance and store them in the refrigerator until ready to grill.

Final Thoughts
These Coastal Garden Haddock Pouches are one of my favorite summer dinners because they combine fresh vegetables, flaky fish, and easy cleanup in one simple package. Plus, the combination of Old Bay, lemon, garlic, and green olives gives this recipe a coastal-inspired flavor that feels a little different from traditional foil packet meals.
