Ingredients You’ll Need
Preparing this baked swordfish is a breeze because the ingredients are both simple and thoughtfully chosen, each adding flavor, moisture, or texture that complements the natural richness of the fish.
- 2 swordfish steaks (6 ounces each): Choose fresh, firm steaks for the best flavor and texture.
- 1/2 teaspoon sea salt: Enhances the natural flavors without overpowering the delicate fish.
- 3 tablespoons olive oil: Adds richness and helps keep the fish moist during baking.
- 2 tablespoons lemon juice: Offers a bright citrus kick that lifts the entire dish.
- 1 teaspoon lemon zest: Provides an intense lemon aroma and a touch of bitterness to balance the dish.
- 3 cloves garlic (thinly sliced): Adds a fragrant, savory depth when baked alongside the fish.
- 2 shallots (thinly sliced): Deliver a mild, sweet onion flavor that caramelizes slightly as they bake.
How to Make Baked Swordfish with Lemon, Garlic, and Shallots Recipe
Step 1: Preheat Your Oven
Start by heating your oven to 400 degrees Fahrenheit. This temperature ensures the swordfish will cook evenly, gaining a lovely tender texture without drying out.
Step 2: Prepare the Flavorful Olive Oil Mixture
In a small bowl, combine the olive oil, lemon juice, lemon zest, sliced garlic, and shallots. Stir gently until all the ingredients blend beautifully, creating a vibrant marinade that will infuse the swordfish with tons of flavor.
Step 3: Arrange the Swordfish
Lay the swordfish steaks on a parchment-lined, rimmed baking sheet or baking dish. The parchment makes cleanup easier and prevents the fish from sticking while baking.
Step 4: Apply the Marinade and Toppings
Brush the olive oil and lemon mixture generously onto both sides of each swordfish steak. Then, spoon the remaining garlic and shallots on top. This layering allows every bite to be bursting with those irresistible aromatic hints.
Step 5: Bake Until Perfectly Cooked
Place your baking dish in the preheated oven and bake for about 10 to 15 minutes. The swordfish is done when it reaches an internal temperature of 145 degrees Fahrenheit, firm yet moist, with the edges slightly golden.
Step 6: Serve Immediately
Once out of the oven, serve the fish right away to enjoy the flavors at their freshest and the texture at its peak.
How to Serve Baked Swordfish with Lemon, Garlic, and Shallots Recipe

Garnishes
A sprinkle of fresh parsley or chopped chives adds a pop of green and freshness, while a few thin lemon slices on the side can brighten up each bite. For an extra touch of elegance, drizzle a little more olive oil or a light drizzle of balsamic glaze.
Side Dishes
This dish pairs exceptionally well with simple sides like steamed asparagus, roasted baby potatoes, or a crisp mixed green salad. The subtle, fresh flavors of these sides won’t compete but instead complement the brightness and garlic undertones of the swordfish.
Creative Ways to Present
For a fun twist, serve the baked swordfish over a bed of herbed quinoa or couscous studded with slivered almonds and dried cranberries. Alternately, plating alongside a vibrant ratatouille or a dollop of garlic mashed cauliflower adds both color and character to your dinner table.
Make Ahead and Storage
Storing Leftovers
If you happen to have leftovers—which might be unlikely given how delicious this dish is—store them in an airtight container in the refrigerator. Consume within 1 to 2 days for the best taste and texture.
Freezing
While fresh swordfish shines brightest, you can freeze cooked portions if needed. Wrap the fish tightly in plastic wrap and foil, then place in a freezer-safe bag or container. Use within 1 month for best results.
Reheating
To reheat, gently warm your swordfish in a low-temperature oven (around 275 degrees Fahrenheit) or use a microwave on a low setting to avoid drying out the fish. Adding a small splash of water or lemon juice before reheating helps maintain moisture.
FAQs
Can I use frozen swordfish for this recipe?
Absolutely! Just make sure to thaw the swordfish completely in the fridge before preparing to ensure even cooking and a tender texture.
Is there a substitute for shallots?
If shallots aren’t available, finely diced mild onions or leeks can work as substitutes, though shallots add a unique sweetness and subtle complexity that is ideal.
How can I tell when the swordfish is fully cooked?
The safest and most precise method is to use an instant-read thermometer. The swordfish should reach 145 degrees Fahrenheit internally. The flesh will be opaque and flake easily when gently pressed.
Can I marinate the swordfish ahead of time?
You can marinate the swordfish for up to 30 minutes before baking. However, avoid marinating too long as the lemon juice can start to “cook” the fish, altering its texture.
What if I don’t have parchment paper?
No worries! You can lightly grease the baking dish or use aluminum foil to prevent sticking, though parchment paper usually gives the best non-stick results.
