Ingredients for Baked Swordfish with Garlic Herb Butter
Main Ingredients:
- Swordfish fillets (2) – Fresh, thick-cut fillets work best for a juicy texture.
- Unsalted butter (4 tbsp) – Adds richness and helps keep the fish tender.
- Garlic (3 cloves, minced) – Infuses the butter with a deep, savory aroma.
Seasonings & Herbs:
- Fresh parsley (2 tbsp, chopped) – Brings a fresh, vibrant flavor.
- Thyme or rosemary (1 tsp, chopped) – Adds a subtle, earthy taste.
- Sea salt & black pepper (to taste) – Enhances the fish’s natural flavor.
Additional Flavor Boosters:
- Olive oil (1 tbsp) – Helps prevent the fillets from drying out.
- Lemon juice (2 tbsp) – Brightens the dish with a fresh, tangy contrast.
- Red pepper flakes (optional, ½ tsp) – Adds a slight kick for spice lovers.
Step-by-Step Guide to Baking Swordfish Perfectly
1. Preheat the Oven
Begin by preheating your oven to 400°F (200°C). This high temperature helps the swordfish cook quickly while keeping it tender. Lightly grease a baking dish or line it with parchment paper to prevent sticking.
2. Prepare the Garlic Herb Butter
In a small bowl, combine melted butter, minced garlic, chopped parsley, thyme, salt, pepper, and lemon juice. Stir well to create a rich, flavorful butter sauce.
3. Season the Swordfish
Pat the swordfish fillets dry with a paper towel. Then, brush both sides with olive oil and season generously with salt, pepper, and red pepper flakes (if using).
4. Bake the Swordfish
Place the fillets in the prepared baking dish. Spoon the garlic herb butter over the top, ensuring even coverage. Bake for 12-15 minutes, depending on thickness, until the fish flakes easily with a fork.
5. Serve and Enjoy
Once done, remove the swordfish from the oven and let it rest for 2 minutes. Garnish with fresh parsley and lemon slices, then serve with your favorite sides.

Best Side Dishes to Serve with Baked Swordfish
Pairing the right side dishes with Baked Swordfish with Garlic Herb Butter enhances its flavors and creates a well-balanced meal. Here are some of the best options:
1. Roasted Vegetables
Oven-roasted asparagus, Brussels sprouts, or zucchini complement the rich, buttery swordfish while adding texture and nutrients. Simply toss them with olive oil, salt, and pepper, then roast at 400°F (200°C) for 15-20 minutes.
2. Garlic Butter Rice
A side of fluffy rice infused with garlic and butter pairs beautifully with the flavors of the swordfish. The rice absorbs the delicious juices, making every bite more flavorful. For a healthier option, try quinoa or cauliflower rice.
3. Fresh Green Salad
A light, crisp salad with mixed greens, cherry tomatoes, cucumber, and feta cheese balances the richness of the swordfish. For extra freshness, dress it with a lemon vinaigrette.
4. Garlic Mashed Potatoes
Creamy mashed potatoes with roasted garlic provide a hearty and comforting side. The smooth texture and buttery taste complement the firm, flaky swordfish.
5. Grilled or Steamed Asparagus
Lightly grilled or steamed asparagus spears add a fresh, slightly crisp contrast to the dish. A drizzle of olive oil and lemon juice enhances their flavor.
Expert Tips & Common Mistakes to Avoid
Follow these expert tips to make sure your Baked Swordfish with Garlic Herb Butter turns out perfect every time.
Expert Tips
- Choose fresh swordfish – Look for fillets that are firm, moist, and have a clean, ocean-like smell. Freshness plays a key role in the final taste.
- Bake at the right temperature – Cooking at 400°F (200°C) ensures the fish remains juicy and tender while developing a delicious golden-brown crust.
- Use garlic herb butter generously – The butter mixture not only enhances flavor but also helps keep the fish moist. Spoon some over the fillets before and after baking for extra richness.
- Let the swordfish rest – Allowing the fish to sit for two minutes after baking helps retain its natural juices, keeping every bite flavorful.
Common Mistakes to Avoid
- Overcooking the fish – Swordfish can dry out quickly. To prevent this, remove it from the oven when the internal temperature reaches 135°F (57°C) and let it rest to finish cooking.
- Skipping the seasoning – While swordfish has a mild, naturally delicious taste, seasoning with salt, pepper, and lemon juice enhances its flavor. Don’t be afraid to add herbs and spices.
- Using too much oil – A light brush of olive oil is enough to prevent dryness. Overusing oil can make the fish greasy and overpower its delicate flavor.
