Ingredients
- 2 tuna steaks (about 6 oz each)
- 3 tablespoons olive oil (for marinade)
- 2 cloves garlic, minced
- 3 tablespoons lemon juice
- 1 teaspoon lemon zest
- 1/2 teaspoon salt
- 1/4 teaspoon freshly ground black pepper
- 1 bunch asparagus (about 1 lb), trimmed
- 1 tablespoon olive oil (for asparagus)
- Salt and pepper, to taste (for asparagus)
- Fresh parsley, chopped (for garnish)
- Lemon wedges (for serving)
Instructions
- Prepare the Marinade: In a bowl, combine olive oil, minced garlic, lemon juice, lemon zest, salt, and black pepper.
- Marinate the Tuna: Place the tuna steaks in a shallow dish and pour the marinade over them. Let them marinate for at least 30 minutes in the refrigerator.
- Preheat the Grill: Preheat your grill to medium-high heat.
- Grill the Tuna: Remove the tuna from the marinade and place it on the grill. Cook for about 4-5 minutes on each side for medium-rare, or until your desired doneness.
- Grill the Asparagus: While the tuna is cooking, toss the asparagus with a little olive oil, salt, and pepper. Grill the asparagus for about 3-4 minutes, turning occasionally, until tender and slightly charred.
- Serve: Plate the grilled tuna steaks with asparagus on the side. Garnish with fresh parsley and additional lemon wedges if desired.
Cook’s tips
- For the best flavor, let the tuna marinate for at least 30 minutes, but no more than 1 hour—over-marinating can break down the fish's texture.
- Pat the tuna steaks dry before grilling to get a nice sear and prevent sticking.
- Preheat the grill properly and oil the grates lightly to avoid the fish sticking.
- Cook tuna to medium-rare (about 4-5 minutes per side) for the juiciest results; it will continue cooking slightly off the heat.
- When grilling asparagus, keep them whole or cut into large spears so they don't fall through the grates.
Substitutions
- Use swordfish or mahi-mahi instead of tuna for a different but equally delicious fish.
- Substitute lime juice and zest for lemon to give the dish a more tropical twist.
- Swap fresh parsley with cilantro or basil for a different herbaceous note.
- If you don't have fresh garlic, use 1/2 teaspoon garlic powder in the marinade.
- Try broccolini or green beans instead of asparagus for a variation in veggies.
Storage & reheating
Store any leftovers in an airtight container in the refrigerator for up to 2 days. To reheat, gently warm the tuna and asparagus in a skillet over medium heat for 1-2 minutes per side, or enjoy them cold in a salad.
Frequently asked questions
Can I use frozen tuna steaks?
Yes, but make sure to thaw them completely in the refrigerator before marinating. Pat them dry thoroughly to remove excess moisture for better grilling.
How do I know when the tuna is cooked to my liking?
For medium-rare, the tuna should be opaque on the outside but still pink and moist in the center. Use a meat thermometer to check: 125°F (52°C) for rare, 130°F (54°C) for medium-rare, and 140°F (60°C) for medium. Remember it will continue cooking a bit after removal from the grill.
Can I cook this on a stovetop grill pan instead of an outdoor grill?
Absolutely! Use a grill pan over medium-high heat. You'll get similar char marks and flavor. Just make sure the pan is well-heated and lightly oiled.
What can I serve with this dish besides asparagus?
This tuna pairs well with a side of quinoa, couscous, or a simple green salad. You could also serve it with roasted potatoes or a crusty bread to soak up any leftover marinade.
