Notes
Tips and Tricks
Rest the Tuna – Let the steaks rest for 3 minutes after grilling to keep them juicy. Grill Lemon Slices – A quick char on the lemon slices adds a subtle smoky flavor. Sauce Consistency – Whisk the lemon butter sauce constantly over low heat so it thickens without separating.Storing and Reheating
Store – Refrigerate cooked tuna steaks and sauce separately in airtight containers for up to 2 days. Reheat on Stovetop – Warm the tuna in a skillet over low heat, adding a splash of olive oil. Warm the sauce gently in a small saucepan until smooth.Nutrition
