Lemon Garlic Tuna Steaks

May 6, 2020 | Main Meals

Lean, excellent source of protein and satisfying! I love tuna steaks, they are such a favorite in my household. It’s early May and we were blessed with a warm Friday evening, so Grilled tuna steaks just felt like the perfect meal for this warm Friday night. Vinny and I enjoyed it with a chilled glass of white Sancerre.

Be sure to reserve 30 minutes to marinate the steaks, it makes all the difference. Don’t go beyond 30 minutes on fish, otherwise the flesh will start to “cook” from the acid of the lemon. You want just enough to add moisture and flavor. I hope you enjoy it as much as we did!
