Ingredients

1. 4 cod fillets (about 6 ounces each)
2. 1 pound fresh green beans, trimmed
3. 2 lemons (zested and juiced)
4. 3 tablespoons olive oil
5. 2 cloves garlic, minced
6. Salt and freshly ground black pepper, to taste
7. 1 teaspoon dried oregano (or 1 tablespoon fresh)
8. Fresh parsley, chopped (for garnish)

Substitution Options

• Swap cod for tilapia, haddock, or even salmon if you prefer.
• Use frozen green beans if fresh ones aren’t available—just thaw them first.
• If you’re out of lemons, try lime juice or a splash of white wine vinegar for acidity.
• Olive oil can be replaced with avocado oil or melted butter for a richer flavor.

Preparation Section

Step 1: Preheat Your Oven

Start by preheating your oven to 400°F (200°C). This is the ideal temperature for baking cod. Many people ask, What temperature does cod cook at? Well, 400°F is just right—it ensures the fish cooks evenly without drying out. While the oven heats up, line a large baking sheet with parchment paper. This makes cleanup a breeze!

Step 2: Prep the Green Beans

Toss the trimmed green beans with a tablespoon of olive oil, half the minced garlic, salt, and pepper. Spread them out on one side of the baking sheet. Pro tip: don’t overcrowd the pan. Giving the beans space helps them roast instead of steam, resulting in a deliciously crispy texture.

Step 3: Season the Cod

Pat the cod fillets dry with paper towels—this step is crucial for getting a nice sear. Place the fillets on the other side of the baking sheet. Drizzle them with the remaining olive oil and sprinkle with salt, pepper, oregano, and the rest of the garlic. Squeeze fresh lemon juice over the top and add some zest for extra brightness. Chef’s tip: rub the seasoning gently into the fish to ensure every bite is flavorful.

Step 4: Bake Everything Together

Pop the baking sheet into the oven and bake for 12–15 minutes. How long does cod take in the oven at 400 degrees? About 12 minutes for perfectly flaky fish. You’ll know it’s done when the cod flakes easily with a fork. The green beans should be tender-crisp and slightly caramelized around the edges. Garnish with fresh parsley before serving.

Timing

Here’s a quick breakdown of the timing: Prep time takes about 10 minutes, cooking time is 15 minutes, and there’s no resting time needed. In total, you’ll have dinner on the table in under 30 minutes. Who says fast food has to come from a drive-thru?

Chef’s Secret

For an extra layer of flavor, sprinkle a pinch of red pepper flakes over the cod before baking. It adds a subtle heat that complements the lemon beautifully. Trust me, it’s a game-changer!

Extra Info

Storage

Leftovers of Baked Cod & Green Beans with Lemon can be stored in an airtight container in the fridge for up to 2 days. Reheat gently in the oven or microwave to preserve the texture of the fish. Avoid freezing this dish, as the cod may become mushy when thawed. If you plan to store the components separately, keep the green beans in one container and the cod in another. This prevents the fish from making the veggies soggy. Pro tip: save any leftover lemon wedges to brighten up future meals. A squeeze of lemon can transform leftovers into something exciting again!

Tips and Advice

• Always pat the cod dry before seasoning—it helps achieve better browning.
• Don’t skip the lemon zest; it adds a burst of citrus flavor that juice alone can’t provide.
• If you’re unsure whether the cod is cooked, check its internal temperature. It should read 145°F (63°C).

Presentation Tips

• Serve the dish on a platter with the green beans arranged neatly around the cod fillets.
• Garnish with additional lemon slices and a sprinkle of fresh herbs for color.
• Drizzle a little extra olive oil over the top for a glossy finish.

1. Grilled Cod & Asparagus: Swap green beans for asparagus and grill everything for a smoky twist.
2. Lemon Herb Salmon: Use salmon instead of cod and add thyme or rosemary for depth.
3. Sheet Pan Shrimp & Broccoli: Replace cod with shrimp and use broccoli for a low-carb option.
4. Mediterranean Cod: Top the cod with diced tomatoes, olives, and feta before baking.
5. Spicy Baked Cod: Add chili powder and cayenne for a fiery kick.
6. Vegan Green Bean Medley: Omit the fish and toss green beans with chickpeas and spices for a plant-based dish.

Common Mistakes to Avoid

Mistake 1: Overcooking the Cod

Overcooked cod becomes dry and loses its delicate texture. To avoid this, set a timer and check the fish after 10 minutes. Remember, it continues to cook slightly even after you remove it from the oven.

Mistake 2: Skipping the Lemon Zest

Some folks only use lemon juice and miss out on the zest’s intense flavor. Always zest the lemon before juicing it—it’s a small step that makes a big difference.

Mistake 3: Covering the Cod While Baking

Do I cover cod when baking? Nope! Covering traps moisture and prevents the fish from developing a nice golden crust. Leave it uncovered for best results.
