Ingredients

For the fish

1.5 to 2 pounds cod fillets (about 4 fillets), patted dry
1 teaspoon salt (use less if your Old Bay is salty)
1/2 teaspoon black pepper

For the garlic butter

4 tablespoons unsalted butter, melted (or softened and melted)
3 garlic cloves, minced (about 1 tablespoon)
1 tablespoon lemon juice (fresh)
1 teaspoon lemon zest
1 to 1 1/2 teaspoons Old Bay seasoning (adjust to taste)
1 tablespoon olive oil (to brush fish briefly)

To finish

2 tablespoons chopped fresh parsley (optional)
Lemon wedges for serving

Notes: Use unsalted butter so you can control salt. Fresh lemon brightens the dish; bottled juice will work in a pinch.

How to Make Baked Old Bay Garlic Butter Cod

Preheat your oven to 400°F (200°C). Lightly oil a baking dish or line with foil for easier cleanup.

Tip: Preheating gives even cooking so the fish cooks through without drying.

Pat the cod fillets dry with paper towels and place them in the prepared dish. Brush each fillet lightly with olive oil and season with salt and pepper.

Why this matters: Drying the fish helps the garlic butter stick and improves browning at the edges.

In a small bowl, mix melted butter, minced garlic, lemon juice, lemon zest, and Old Bay until blended.

Mini-tip: Let the garlic sit in the warm butter for a minute to bloom its flavor.

Spoon the garlic butter evenly over each fillet, making sure some butter gets under the edges.

Why this step matters: Butter under the fish keeps it moist and delivers flavor through the fillet.

Bake uncovered in the preheated oven for 10–14 minutes, depending on thickness, until the fish flakes easily with a fork and looks opaque. A thicker fillet may take a little longer.

Tip: Check at 10 minutes; overcooking makes cod dry. The center should feel tender and warm.

If you like a light golden top, broil on high for 1–2 minutes—watch closely so it doesn’t burn. Remove from oven and let rest for 2 minutes. Sprinkle with chopped parsley and serve with lemon wedges.

Mini-tip: Resting lets juices settle so the fillet stays moist.

How to Serve Baked Old Bay Garlic Butter Cod

Serve over steamed rice or buttery mashed potatoes to catch the garlic butter sauce.
Add roasted vegetables or a simple green salad for freshness and color.
Garnish with lemon wedges and extra parsley; a slice of crusty bread soaks up the buttery juices.

How to Store Baked Old Bay Garlic Butter Cod

Fridge: Cool to room temperature, then store in an airtight container for up to 3 days.
Freezer: Wrap individual fillets tightly in foil and place in a freezer bag for up to 2 months. Thaw overnight in the fridge before reheating.
Reheat: Warm gently in a 275°F (135°C) oven covered with foil for 10–15 minutes until heated through. Avoid microwave reheating when possible to keep texture flaky and not rubbery.

Tips to Make Baked Old Bay Garlic Butter Cod

Use fresh lemon and garlic for the brightest flavor.
Don’t overbake — check at the shorter time and judge by flakiness.
If your Old Bay is salty, reduce added salt.
Let butter sit with garlic a minute to mellow the raw edge.

Variation

Swap the cod for haddock or pollock for a similar mild flavor.
Make it gluten-free by serving with a gluten-free grain or potatoes (no change needed in the recipe).
For a vegetarian twist, roast cauliflower steaks with the same garlic butter and Old Bay for a similar savory hit.

FAQs

Can I use frozen cod?

Yes. Thaw it fully in the fridge overnight and pat dry before using. Patting dry prevents extra moisture so the butter and seasonings stick and the fish bakes properly.

What can I substitute for Old Bay?

Use a mix of 1/2 teaspoon paprika, 1/4 teaspoon celery salt, and a pinch of cayenne for a similar warm, herby flavor. Adjust to taste.

How do I tell when the cod is done?

The fish is done when it turns opaque, flakes easily with a fork, and feels tender. If you use a thermometer, aim for 145°F (63°C) in the thickest part.

Can I make this ahead of time?

You can mix the garlic butter ahead and keep it refrigerated. Spoon it on just before baking to keep flavors bright.
