Ingredients
- 4 haddock fillets
- 2 tablespoons olive oil
- Juice of 1 lemon
- 1 tablespoon capers, rinsed and drained
- 2 cloves garlic, minced
- Salt and pepper to taste
- 1 teaspoon fresh parsley, chopped (for garnish)
- 2 cups mixed greens (such as broccoli, green beans, and zucchini)
- 1 tablespoon butter
Instructions
- Preheat the Oven: Preheat your oven to 400°F (200°C).
- Prepare the Haddock: Place the haddock fillets in a baking dish. Drizzle with olive oil, lemon juice, and sprinkle with capers and minced garlic. Season with salt and pepper.
- Bake the Fish: Bake in the preheated oven for 15-20 minutes, or until the fish is opaque and flakes easily with a fork.
- Steam the Greens: While the fish is baking, steam the mixed greens until just tender, about 5-7 minutes. Toss with butter and season with salt and pepper.
- Serve: Plate the baked haddock alongside the steamed greens, garnishing with fresh parsley and an extra squeeze of lemon if desired.
Cook’s tips
- Pat the haddock fillets dry with paper towels before seasoning to help them brown and prevent excess moisture.
- Use freshly squeezed lemon juice for the best flavor; bottled juice can taste flat and overly acidic.
- For a golden crust, switch the oven to broil for the last 2 minutes of baking, watching carefully to avoid burning.
- Check the fish early—it's done when it flakes easily with a fork and reaches an internal temperature of 145°F (63°C).
- Steam the greens just until crisp-tender; overcooking will make them mushy and lose their vibrant color.
Substitutions
- Use cod, tilapia, or halibut instead of haddock for a similar flaky white fish.
- Substitute lime juice for lemon juice to give the dish a different citrus twist.
- If you don't have capers, chopped green olives or pickled jalapeños can provide a similar briny kick.
- Replace the butter with olive oil or ghee for a dairy-free option when tossing the greens.
- Add a pinch of red pepper flakes or a dash of smoked paprika to the fish for extra depth of flavor.
Storage & reheating
Store leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm in the oven at 300°F (150°C) or microwave in short bursts, adding a splash of lemon juice or water to keep the fish moist.
Frequently asked questions
Can I use frozen haddock fillets?
Yes, thaw the fillets completely in the refrigerator overnight, then pat them dry before seasoning. Adjust baking time if needed, as frozen fish may release more moisture.
How do I know when the haddock is fully cooked?
The fish should be opaque and flake easily with a fork. For accuracy, you can check the internal temperature—it should reach 145°F (63°C).
Can I prepare this dish ahead of time?
You can season the fish and keep it covered in the refrigerator for up to 4 hours before baking. The greens are best steamed fresh, but you can prep them by washing and chopping ahead.
What if I don't have mixed greens?
Feel free to use any quick-cooking vegetables like asparagus, broccoli florets, green beans, or spinach. Adjust the steaming time based on the vegetable's thickness.
