How to Make Sheet Pan Lemon Herb Tuna
Full directions for the tuna recipe, are in the printable recipe card below. This is a quick walk-through on how to make!
Mix up your tuna fish marinade in a bag, and then place your tuna inside and marinate in the fridge as directed.
Next wash, prep and season the potatoes. Then store them in a bag in the fridge until ready to cook as well.
Place the tuna and potatoes on your prepared sheet pan and bake in the oven as directed.
Flip half way through. This is important to ensure the tuna cooked evenly, plus you will find it is great for the potatoes as well.
Once done, remove and serve up your easy and quick tuna recipe.
How to Know When Tuna Is Done?
Grab a meat thermometer and make sure the internal temperature reads 140-145 degrees for well done. Or if you want a medium rare, go for 125 degrees.
You will find that many prefer to eat tuna at different internal temperatures. The biggest thing is to make sure you cook your tuna to a safe degree.
If you don’t eat all your tuna you can store leftovers in the fridge for 1-2 days. You will find that fish can spoil faster, so always use your best judgement in terms of quality. If stored improperly you will find it can go bad. So ensure it is a sealed container and at proper temperature.
Depending on how you buy your tuna you will find most tuna steaks do not have bone. Now if they are sold cut differently then they could have a bone in them. Tuna is a very large fish, so it is easy for them to make it into boneless fish steaks.
We love potatoes, salad, or even your favorite vegetable side dish. Tuna is very versatile in terms of what you can pair with it.
