Common Mistakes to Avoid
Cooking tuna steaks can be tricky if you’re not aware of some common pitfalls. Here are a few mistakes to watch out for:
- Not Preheating the Skillet: Failing to preheat your skillet can lead to uneven cooking. Always heat the skillet before adding the tuna for a nice sear.
- Overcooking the Tuna: Tuna is best enjoyed medium-rare. Cooking it too long makes it dry. Aim for 2–3 minutes per side for perfect doneness.
- Ignoring Seasoning: Skip the salt and pepper, and your steaks won’t shine. Generously season both sides of the tuna before cooking.
- Neglecting Veggie Prep: If you don’t cut root vegetables uniformly, they’ll cook unevenly. Chop them into similar sizes for consistent roasting.
- Skipping the Resting Time: Cutting into your tuna right after cooking can make it lose juices. Let it rest for a few minutes before slicing.
