Cod is a wonderfully versatile white fish that absorbs the bright acidity of lemon and the aromatic punch of garlic beautifully. By roasting the asparagus and cherry tomatoes on the same tray, the vegetable juices meld with the herb marinade to create a light, natural sauce.

Instructions

Step 1

Step 2
In a small bowl, combine 2 tablespoons olive oil, lemon zest and juice, minced garlic, parsley, thyme, salt, and pepper.
Step 3
Pat the cod fillets dry with paper towels. Place them on one side of the baking sheet. Brush the lemon herb mixture evenly over the fillets.
Step 4
Place the asparagus and cherry tomatoes on the other side of the baking sheet. Drizzle with 1 tablespoon olive oil, sprinkle with salt and pepper, and toss to coat.

Step 6
Divide the cod and vegetables among plates. Garnish with lemon wedges and extra herbs if desired. Serve immediately.

Zusatztipps für die Zubereitung

For the best texture, ensure you pat the cod fillets completely dry with paper towels before applying the herb mixture. This helps the seasoning stick and ensures the fish bakes properly rather than steaming on the pan.

Varianten und Anpassungen

You can easily substitute cod with other white fish like haddock or halibut. If you want an extra layer of flavor, try adding a sprinkle of Parmesan cheese over the asparagus during the last five minutes of roasting.

Serviervorschläge

This sheet pan meal is a complete gluten-free dinner on its own, but you can serve it with quinoa, rice, or crusty bread for a more substantial feast. It pairs beautifully with a crisp white wine such as Sauvignon Blanc or Pinot Grigio.

Recipe FAQs

Can I use frozen cod fillets?

Yes, thaw frozen cod completely before cooking. Pat the fillets dry with paper towels to remove excess moisture, which ensures proper seasoning absorption and prevents sogginess during baking.

What other white fish work well?

Haddock, halibut, sea bass, or tiliga are excellent substitutes. Adjust cooking time slightly depending on thickness—thinner fillets may need 2-3 minutes less, while thicker cuts might require an extra minute or two.

How do I know when the cod is done?

The cod is ready when it flakes easily with a fork and appears opaque throughout. The internal temperature should reach 63°C (145°F). Avoid overcooking, as the fish will become dry and lose its delicate texture.

Can I prepare this ahead?

Mix the lemon herb marinade up to 24 hours in advance and store refrigerated. The vegetables can be trimmed and halved earlier in the day. However, assemble and bake just before serving for the best texture and flavor.

What sides complement this dish?

Quinoa, couscous, or crusty bread soak up the flavorful juices. A crisp white wine like Sauvignon Blanc or Pinot Grigio pairs beautifully. For a lighter option, serve over mixed greens with a light vinaigrette.

How can I add more flavor?

Add capers or olives to the vegetable mix, sprinkle Parmesan over asparagus during the last 5 minutes, or finish with red pepper flakes. A drizzle of high-quality olive oil before serving enhances richness.
