Cooking fish at home used to make me nervous. I worried about getting the timing right and whether it would turn out too dry. But ever since I discovered oven-baked swordfish, I’ve become much more confident in my fish-cooking game. There’s something so satisfying about pulling a perfectly cooked piece of swordfish from the oven.
What I really love about this method is how straightforward it is. No fancy techniques or special equipment needed – just a sheet pan and your oven. I often prep everything while my kids are finishing their homework, and dinner’s ready by the time my husband walks through the door. The best part? Clean-up is minimal, which means more time to actually sit down and enjoy dinner with the family.
If you’ve been hesitant about cooking fish at home, this recipe might just change your mind. It’s simple enough for busy weeknights but nice enough for when you want to impress dinner guests.

What Kind of Swordfish Should I Use?
When shopping for swordfish, look for steaks that are firm and have a pinkish-beige color with no brown spots or discoloration. Fresh swordfish steaks should be about 1 to 1½ inches thick – any thinner and they might dry out during cooking. While fresh is great if you can find it, frozen swordfish steaks are totally fine too and are often more readily available at regular grocery stores. Just make sure to thaw them completely in the refrigerator before cooking and pat them dry with paper towels to remove any excess moisture. If you’re worried about sustainability, look for swordfish labeled as “harpoon-caught” or “line-caught,” as these are typically more environmentally friendly fishing methods.
Options for Substitutions
Need to make some swaps? Here are some helpful substitutions for this recipe:
- Swordfish steaks: If you can’t find swordfish, you can use other firm, meaty fish like mahi-mahi, tuna steaks, or halibut. Just keep in mind that cooking times might need to be adjusted – thinner fish will cook faster than thick swordfish steaks.
- Paprika: Regular paprika can be swapped with smoked paprika for a deeper flavor, or you can use a mix of sweet red pepper powder and a tiny pinch of cayenne.
- Dried parsley: Fresh parsley works great too – just use 1 tablespoon of fresh instead of 1 teaspoon dried. You could also use dried basil or oregano for a different flavor profile.
- Olive oil: Any neutral cooking oil like avocado oil or grapeseed oil will work just fine. Even melted butter is a tasty option.
- Garlic powder: Fresh minced garlic is a great substitute – use 2 small cloves. You can also use granulated garlic, just use the same amount as the powder.
Watch Out for These Mistakes While Cooking
The biggest mistake when cooking swordfish is overcooking it, which can turn this meaty fish dry and tough – aim for an internal temperature of 145°F and remember that the fish will continue cooking for a few minutes after you take it out of the oven. Another common error is not patting the fish dry before seasoning, which prevents the spices from sticking properly and can create steam instead of a nice crust – take an extra minute to thoroughly dry the steaks with paper towels. To get the most flavor, avoid cooking the swordfish straight from the fridge; instead, let it rest at room temperature for 15-20 minutes before cooking, which helps it cook more evenly and develop a better sear. For the best texture, try marinating the fish for no longer than 30 minutes, as the acids in marinades can start breaking down the flesh and make it mushy if left too long.
What to Serve With Swordfish?
Since swordfish has such a meaty, rich texture, it pairs really well with light and fresh side dishes. A simple lemon rice pilaf or roasted garlic potatoes make great starchy sides that won’t overpower the fish. For vegetables, try grilled asparagus or a Mediterranean-style salad with cucumbers, tomatoes, and red onions dressed in olive oil and lemon juice. I also love serving swordfish with a quick herb sauce like chimichurri or gremolata on the side – the bright, fresh flavors really complement the smoky paprika seasoning on the fish.
Storage Instructions
Keep Fresh: Once your swordfish has cooled down, place it in an airtight container and pop it in the fridge. It’ll stay good for up to 2 days. The sooner you eat it though, the better it’ll taste – fish is always best when it’s fresh!
Make Ahead: You can prep the seasoning mix ahead of time and store it in a small jar or container. When you’re ready to cook, just pat the fish dry and add your pre-mixed seasonings. This makes weeknight cooking so much easier!
Warm Up: To enjoy leftover swordfish, gently warm it in the microwave at 50% power in 30-second intervals until just heated through. Be careful not to overheat, as this can make the fish tough and dry. You can also enjoy it cold on top of a salad!

Ingredients
- 4 swordfish steaks
- 1 teaspoon paprika
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1/8 teaspoon crushed red pepper
- 1 teaspoon dried parsley
- 1/2 teaspoon garlic powder
- 2 teaspoons olive oil
Step 1: Preheat the Oven
Begin by preheating your oven to 400°F (200°C).
This will ensure that your oven is at the right temperature when the swordfish is ready to be baked.
Step 2: Prepare the Swordfish
Coat the swordfish fillets with olive oil, making sure they are well covered.
Season the fillets thoroughly on all sides with your choice of seasonings, such as salt, pepper, and any additional herbs or spices you prefer.
Step 3: Sear the Swordfish
Warm a grill pan or cast iron pan over medium heat.
Once hot, add the seasoned swordfish fillets to the pan.
Cook each side for about 2 minutes, or until the surface becomes lightly golden or brown.
This quick sear helps to lock in flavors.
Step 4: Bake the Swordfish
After searing, place the pan directly in the preheated oven if it is oven-safe.
If not, transfer the swordfish to an oven-safe baking dish.
Bake the swordfish for roughly 10 minutes, or until the fillets are cooked through and appear white throughout.
Step 5: Serve the Swordfish
Carefully remove the swordfish from the oven once fully cooked.
Serve the fillets warm, perhaps with a side of vegetables or a fresh salad for a complete meal.
