How to Make this

Print Recipe (No Advertisments)

1. In a bowl whisk together 1/4 cup low sodium soy sauce, 2 tablespoons extra virgin olive oil, 2 tablespoons fresh lemon juice, 1 tablespoon honey, 2 cloves minced garlic, 1 teaspoon grated fresh ginger, 1 teaspoon toasted sesame oil and 1/4 teaspoon freshly ground black pepper until honey is dissolved and the mixture is uniform.

2. Taste and adjust seasoning if needed, adding a little more lemon or honey to balance salty and sweet.

3. Place tuna steaks in a shallow dish or resealable plastic bag and pour the marinade over them, turning to coat both sides.

4. Cover and refrigerate for 15 minutes for a light flavor or up to 1 hour for more intensity; do not exceed 2 hours to avoid curing the fish.

5. Remove tuna from the refrigerator 10 minutes before cooking to come closer to room temperature, and remove steaks from the marinade; reserve the marinade if you plan to cook it down as a sauce.

6. Pat the tuna steaks dry with paper towels to ensure a good sear; discard any marinade that contacted raw fish unless you boil it for at least 2 minutes.

7. Heat a heavy skillet or grill over high heat and add a small amount of oil or brush the surface lightly. Sear tuna 1 to 2 minutes per side for rare, 2 to 3 minutes per side for medium, adjusting time for thickness.

8. If desired, bring the reserved marinade to a boil in a small saucepan for 2 to 3 minutes, then reduce heat and simmer 1 to 2 minutes to use as a glaze or sauce.

9. Let the cooked tuna rest 2 minutes, slice against the grain, and serve with the boiled glaze or a squeeze of fresh lemon.

FAQ

Q: How long should I marinate tuna steak? A: 20 to 30 minutes is ideal for flavor without changing the texture; do not exceed 1 hour.

Q: Can I use this marinade for other fish or proteins? A: Yes, it works well for salmon, swordfish, chicken breast, or firm tofu with similar marinating times.

Q: Is it safe to reuse the marinade as a sauce? A: Only if you bring it to a rolling boil for at least 1 minute to kill any bacteria from the raw fish.

Q: What is the best cooking method for seared tuna? A: A very hot skillet or grill for short times yields a nicely seared exterior with a rare center, typically 1 to 2 minutes per side for 1-inch steaks.

Q: Can I make this marinade ahead of time? A: Yes, prepare and refrigerate up to 3 days; stir or whisk before using as oils may separate.

Q: How can I reduce sodium further? A: Use low sodium soy sauce as listed and consider rinsing the tuna briefly before marinating if needed.

Q: Any substitutions for honey? A: Use maple syrup or agave nectar in a 1 to 1 ratio for a similar sweetness and consistency.

Simply Delicious Marinade For Tuna Steak Recipe Substitutions and Variations

Low sodium soy sauce: tamari for gluten free, coconut aminos for lower sodium and a slightly sweet note, or Worcestershire sauce for deeper umami.
Extra virgin olive oil: avocado oil for higher smoke point, grapeseed oil for neutral flavor, or melted light butter for richness.
Fresh lemon juice: lime juice for brighter citrus, rice vinegar for milder acidity, or white wine vinegar diluted 1:1 with water for less sharpness.
Honey: maple syrup for a vegan option and subtle caramel notes, agave nectar for a neutral sweetener, or brown sugar dissolved in a little warm water for molasses depth.

Pro Tips

1. Marinate smartly: keep the time short if you want pristine tuna texture. Acid and salt start to cure the fish, so 15 to 60 minutes is plenty. If you need to prep ahead, remove the steaks from marinade and refrigerate separately after 1 hour.

2. Use the right oil for searing: extra virgin olive oil adds flavor to the marinade but can smoke at high heat. For the pan, choose a neutral high smoke point oil or lightly oil the pan and wipe excess marinade off the fish so you get a clean, dark sear.

3. Handle the reserved marinade safely and usefully: if you want a sauce, bring the reserved liquid to a full rolling boil for at least 2 minutes to kill bacteria, then simmer briefly to concentrate flavors. Or reduce it further into a glaze and finish with a knob of cold butter for shine.

4. Finishing touches matter: let the tuna sit 8 to 10 minutes out of the fridge before cooking for even doneness, and always slice against the grain into thin pieces. A quick squeeze of lemon and a sprinkle of toasted sesame seeds or scallions lifts the flavors at the table.
