Ingredients for Lemon Herb Baked Cod with Garlic Potatoes

For the Potatoes

1 1/2 pounds russet potatoes (680 g), unpeeled and sliced into 1/4-inch (6 mm) rounds
3 garlic cloves, minced
2 tablespoons extra-virgin olive oil (30 ml)
Salt and freshly ground black pepper, to taste

For the Fish

Four (6 to 8 ounce) fresh skinless white fish fillets (cod, haddock, or halibut), 1 to 1 1/2 inches (25 to 38 mm) thick
3 tablespoons unsalted butter (45 g), cut into 1/4-inch (6 mm) pieces
4 sprigs fresh thyme
1 lemon, thinly sliced

Ingredient Notes

If you don’t have cod, you can use any firm white fish such as haddock or halibut. Yukon gold potatoes also work beautifully for a buttery texture. For extra depth, a light drizzle of olive oil after baking adds richness without heaviness.

How to Make Lemon Herb Baked Cod with Garlic Potatoes

Step 1 – Prepare the Oven and Baking Sheet

Preheat the oven to 425°F (220°C) and move the rack to the lower-middle position. Line a rimmed baking sheet with parchment paper for easy cleanup and even roasting.

Step 2 – Par-Cook the Potatoes

In a microwave-safe bowl, combine sliced potatoes, minced garlic, and olive oil. Season generously with salt and pepper. Microwave uncovered for 5 to 10 minutes, stirring once or twice, until the potatoes are just tender.

Step 3 – Assemble and Roast

Arrange the potatoes into four small rectangular stacks (about 4 by 6 inches each). Pat the fish fillets dry with paper towels, season both sides, and place one fillet on each potato stack. Top with small butter pieces, thyme sprigs, and lemon slices. Roast for 15 to 18 minutes until the fish flakes easily with a fork.

The aroma of roasted garlic and thyme will fill your kitchen, creating that irresistible anticipation for dinner.

Pro Tips for Success

• Slice the potatoes evenly to ensure they cook perfectly.
• Don’t skip drying the fish; moisture prevents good roasting.
• Use fresh thyme for that gentle herbal note.
• Check for doneness at 15 minutes — the fish should flake easily.
• Let it rest for 2 minutes before serving for best texture.

Flavor Variations

• Herb Mix-Up: Try rosemary or parsley instead of thyme.
• Citrus Twist: Swap lemon slices for orange or lime for a different brightness.
• Spice Boost: Add a pinch of paprika or chili flakes to the potatoes.
• Creamy Touch: Serve with a drizzle of garlic-infused yogurt sauce.
• Veggie Layer: Add a few zucchini or bell pepper slices under the fish.

Serving Suggestions

Serve this dish straight from the oven while everything is hot and crisp. It pairs beautifully with a light salad or steamed greens. For a comforting side idea, check out this Rustic Potato and Leek Soup – it complements the flavors perfectly on cooler evenings.

Storage and Freezing Instructions

Leftovers can be stored in an airtight container for up to 2 days in the refrigerator. To reheat, place in a 350°F (175°C) oven for about 10 minutes until warmed through. Avoid microwaving the fish for too long, as it can dry out.

You can also prepare the potato stacks in advance and refrigerate them separately from the fish. Just assemble before baking.

FAQ About Lemon Herb Baked Cod with Garlic Potatoes

How do I know when my baked cod is done?

The fish is ready when it flakes easily with a fork and appears opaque throughout. Overcooking can make the fish dry, so start checking around the 15-minute mark.

Can I use frozen fish for this recipe?

Fresh fish gives the best results. However, if you use frozen fillets, make sure to thaw them completely and pat dry before seasoning and baking.

What can I serve with this dish?

Steamed green beans, a crisp salad, or a bowl of Classic Tomato Basil Soup pair wonderfully with this meal. They balance the richness of the potatoes and fish.

Can I make this recipe dairy-free?

Yes, replace butter with olive oil or plant-based butter. It keeps the flavor fresh and satisfying while maintaining the beautiful lemon-herb aroma.

How do I keep the potatoes crispy?

Ensure the potatoes are slightly dry before baking and avoid overcrowding on the pan. This allows air circulation, helping them roast to golden perfection.
