• 3 tbsp olive oil
• Juice of 1 large lemon + 1 tsp zest
• 3 garlic cloves, minced
• 2 tbsp fresh parsley, chopped
• 1 tbsp fresh thyme leaves
• 1 tsp dried oregano
• ½ tsp red pepper flakes (optional)

How to Make Lemon Herb Grilled Swordfish Steaks Step by Step

No drama. Follow these steps and dinner is done.

Step 1 — Make the Marinade

Whisk together olive oil, lemon juice, lemon zest, minced garlic, parsley, thyme, oregano, red pepper flakes, salt, and pepper in a small bowl.

Takes 3 minutes. Do the work.

Step 2 — Marinate the Fish

Place swordfish steaks in a shallow dish or zip-lock bag. Pour marinade over the top.

• Minimum marinade time: 15 minutes
• Maximum: 45 minutes

⚠️ Don't over-marinate. The lemon acid will start breaking down the fish if left too long. Keep it moving — 30 minutes is the sweet spot.

Step 3 — Prep the Grill

Heat grill to medium-high (400–450°F). Clean the grates and oil them lightly with a paper towel dipped in oil.

A hot, clean grill = those beautiful grill marks. Consistent beats perfect, but a preheated grill gets you both.

Step 4 — Grill the Swordfish

Remove steaks from marinade. Pat lightly dry with paper towels — this helps with searing.

Place on grill:

• First side: 5–6 minutes, don't touch it
• Flip once: 4–5 minutes on the second side
• Internal temp target: 145°F

💡 Pro tip: Grill lemon halves cut-side down for 3 minutes alongside the fish. The caramelized lemon squeezed on top at the end is chef's kiss.

Step 5 — Rest and Serve

Pull the steaks off the grill. Let them rest 2–3 minutes before serving.

Top with fresh parsley and a squeeze of that grilled lemon. Done.

Serving Ideas 🍋

Keep it simple. These grilled swordfish steaks pair well with:

• Roasted asparagus or broccolini
• Garlic butter rice or quinoa
• Simple arugula salad with lemon vinaigrette
• Grilled corn on the cob
• Crusty bread to soak up the juices
