Step-by-Step Instructions

This is where the magic happens, and it’s so simple you’ll wonder why you didn’t try it sooner.

Step 1: Prep Your Vegetables

Preheat your oven to 400°F. While it heats, halve your cherry tomatoes and slice your zucchini into half-moons (about a quarter-inch thick).

Step 2: Arrange on Sheet Pan

Spread the tomatoes and zucchini across your sheet pan. Drizzle with 2 tablespoons olive oil, sprinkle with salt, pepper, half the oregano, and half the thyme.

Toss everything together so the veggies are evenly coated.

Step 3: Create Space for Cod

Push the vegetables to the sides of the pan, creating a cleared center area. Pat your cod fillets dry with paper towels, this helps them cook evenly and get slightly crispy on top.

Step 4: Season and Place Cod

Brush the cod fillets with the remaining tablespoon of olive oil. Sprinkle with salt, pepper, minced garlic, and the remaining herbs.

Nestle the cod into the center of your sheet pan, nestled among the vegetables.

Step 5: Roast

Slide the pan into your 400°F oven for 12 to 15 minutes. The cod is done when it flakes easily with a fork and reaches an internal temperature of 145°F.

Step 6: Finish and Serve

Pull the pan from the oven. Squeeze fresh lemon juice over everything and scatter fresh parsley on top if you like.

Serve straight from the pan, family-style, or plate individually. Either way, everyone eats together, and cleanup is a breeze.

Pro Tips for Sheet Pan Success

Sheet pan cooking sounds simple because it is, but a few little tricks make the difference between good and incredible.

Patting your cod dry is the single most important step. Moisture is the enemy of crispy exteriors, so don’t skip it.

Use medium zucchini, not the giant ones. Smaller zucchini cook faster and have better flavor.

Fast Fact: Zucchini is over 95% water, so cooking it on high heat helps release that moisture and concentrate its flavor.

If your fillets are thick (over an inch), give them a 2-minute head start before adding the cod to the pan. This ensures everything finishes at the same time.

Storage and Reheating Tips

Leftovers keep in an airtight container in the fridge for up to 3 days. Reheat gently in a 350°F oven for about 8 minutes, the microwave works in a pinch, but the oven keeps the fish tender.

This dish is also great cold the next day as a salad topper or wrapped in a grain bowl. Add it to your lunch plans if you have leftovers.

Recipe Variations

Cod is a blank canvas, which means you can swap in whatever you love.

Try halibut or haddock if your store doesn’t have fresh cod. Asparagus, bell peppers, and Brussels sprouts all work beautifully in place of zucchini. For herbs, oregano and thyme are classic, but basil or dill are equally delicious.

Want it heartier? Nestle potatoes or pearl onions alongside the veggies. They’ll need the full 15 minutes, so add them first.
