Description

Ingredients
- 2 6 ounce Tuna Steaks approximately 1″ thick
- 1 fresh lemon
- 6 tablespoons extra virgin olive oil divided
- 1 teaspoon salt divided
- 1/2 teaspoon black pepper divided
- 1 teaspoon dried dill weed
- 12 large stalks fresh Asparagus
- 1 teaspoon garlic powder
- 1/3 cup grated parmesan cheese
- 1/2 medium sized onion cut into strips
Instructions
- Set the oven at 400°F. Put the steaks in a bowl that is big enough to handle a little tossing and turning. Now zest and squeeze a lemon into the bowl. Then add the salt, pepper, dill weed and olive oil.
- Gently turn the steaks over a few times to mix up all the ingredients and evenly coat the steaks. When that’s done to your satisfaction line a baking pan, that is just big enough to handle your steaks, with aluminum foil. Use enough foil to stick up higher than the sides of the pan to save yourself some cleanup. Put the steaks and all of the other ingredients in the pan. Use a tablespoon to get the top of the steaks covered with all that good stuff.
- Put that pan aside while you get the asparagus ready. Line a pan, that is just big enough to let all the of the stalks lay on the bottom, with aluminum foil. Again, use enough foil so that it sticks up past the sides of the pan. Cut the ugly end of the stalks off and lay them out in the pan. Cut the onion into strips and add it to the asparagus. Add the olive oil, salt, pepper, garlic powder and the grated parmesan and roll the stalks around getting them covered with all that good stuff.
- Put the pans in the oven and after ten minutes check ’em. The narrower the asparagus stalks are the quicker they will cook. The steaks will get cooked medium well in 10-12 minutes. Poke the asparagus with a fork and the steaks with your finger. The softer the asparagus the more done it is. The firmer the tuna the more done it is. If you are unsure about the tuna just split a steak with the fork to see if it is how YOU like it. Some folks like it raw in the middle and some like it with no pink whatsoever.
- Enjoy your Oven Baked Tuna Steak Dinner.

Tips to Nail Texture and Doneness
How to Know When Your Tuna Is Perfectly Baked
One of the trickiest parts of any baked tuna steak recipe is getting the doneness just right. Tuna cooks fast go a few minutes too long, and it can turn dry and tough. But when it’s done right? It’s tender, juicy, and packed with flavor.
Here’s how to check: press the center of the steak with your finger or a fork. If it feels firm but still has a slight bounce, it’s likely medium-well perfect for most people. Prefer it a little pink in the center? Take it out closer to the 8–10 minute mark. Want it fully cooked? Aim for 12–13 minutes at 400°F.
If you’re unsure, use a fork to gently pull apart the center of one steak. It should flake slightly without looking dry. Remember, tuna continues to cook for a minute or two even after you remove it from the oven.
Adjusting for Thickness
Thicker steaks (around 1 inch) are more forgiving they give you a little wiggle room to get the doneness right. If you’re working with thinner steaks, reduce cook time by a few minutes to avoid overbaking.
This baked tuna steak recipe is meant to be flexible, so trust your instincts and adjust based on your preferences. After a time or two, you’ll know exactly how you like it.

Underseasoning and Skipping the Marinade
Tuna can taste a bit plain without help. That’s why the lemon-herb marinade in this baked tuna steak recipe isn’t just a suggestion it’s essential. Skipping the marinade or under-seasoning your steaks can leave the dish bland and flat. The solution? Don’t hold back. Tuna loves bold flavors like lemon, garlic, dill, and a good drizzle of olive oil.
Using the Wrong Sides
Another common misstep? Pairing tuna with sides that require different cooking times. The beauty of this baked tuna steak recipe is that it works with quick-cooking vegetables like asparagus. If you try pairing it with something like raw potatoes, your timing will be off unless they’re parboiled first.
