Can I use frozen tuna steaks for this recipe?

Technically yes, but trust me on this—fresh is best! If you must use frozen, thaw them overnight in the fridge (no shortcuts!). Pat them obsessively dry with paper towels before seasoning. Frozen tuna tends to release more moisture, and we’re fighting for that perfect sear here. My rule? Reserve frozen tuna for poke bowls and go fresh for these beautiful pan-seared tuna steaks.

How do I store leftover cast iron tuna steaks?

First off—leftovers? Really? (Just teasing!) If you somehow resist eating both steaks, wrap them tightly in plastic and refrigerate for up to 3 days. Reheat gently —30 seconds in the microwave or a quick warm-through in the skillet. But honestly? I love cold leftovers sliced over salads the next day. That protein-packed goodness makes meal planning a breeze!

What’s the ideal thickness for perfect tuna steaks?

1 to 1.5 inches is your goldilocks zone—anything thinner risks drying out, thicker may leave you with an underdone center. My fishmonger knows to cut mine at 1.25″—thick enough for that gorgeous rare interior but still quick-cooking. Pro tip: Ask for "sushi-grade center-cut" steaks—they’ll have the most even thickness for restaurant-style results.

Why did my tuna stick to the skillet?

Three likely culprits: 1) Didn’t preheat long enough (that 5-minute rule isn’t optional!), 2) moved the steaks too soon (let that crust form!), or 3) used a sad, unseasoned skillet. My vintage cast iron gives me flawless releases every time. Also—enough oil! That tablespoon should make the fish practically float when it hits the pan.
