Pan-Seared Tuna Steak: The Perfect Marinade

Tuna steaks are a versatile and tasty meal that can be grilled, seared, baked, or broiled. Marinating tuna steaks can add flavour and tenderise the fish, resulting in a juicy and delicious meal. A marinade is an emulsion of oil, acids such as citrus juice or vinegar, and spices. When preparing a marinade for tuna steaks, it is important to consider the marinating time, as well as the types of spices and ingredients used. In this article, we will explore the steps to create a mouth-watering marinade for tuna steaks and provide tips for achieving the perfect sear when cooking with a pan.

Marinade ingredients: honey, garlic, cumin, lemon juice, salt, pepper, paprika, and cilantro

To make a marinade for tuna steaks, you can combine honey, garlic, cumin, lemon juice, salt, pepper, paprika, and cilantro. This marinade is perfect for grilling, pan-searing, or broiling.

Ingredients:

• Honey
• Minced garlic
• Freshly chopped cilantro
• Freshly chopped parsley
• Salt
• Coarsely cracked black pepper
• Cumin
• Smoked paprika (or regular paprika)
• Lemon juice (freshly squeezed)

Method:

• Combine all the ingredients in a small bowl and whisk vigorously until well combined.
• Place the tuna steaks in a shallow dish and pour the marinade over them. Alternatively, put the tuna steaks in a large Ziploc bag, add the marinade, and toss to coat the steaks.
• Turn the steaks to coat them evenly in the marinade.
• Cover the dish with plastic wrap or seal the bag, pressing out any excess air.
• Transfer to the fridge and chill for at least 30 minutes, turning the steaks occasionally to ensure they absorb all the flavours.
• Preheat your grill, grill pan, or non-stick pan to medium-high heat.
• Remove the tuna steaks from the marinade and shake off any excess.
• Place the steaks on the preheated grill or pan and cook for 6-8 minutes on each side, until easily flaked with a fork and the centre is just barely pink. The internal temperature should be 90-95°F.
• For a perfect sear, ensure your pan is "hot, hot, hot" before adding the tuna steaks.
• Serve immediately with your favourite sides, such as roasted vegetables, rice, or a fresh side salad.

Marinating time: 30 minutes to 2 hours, not longer

When marinating tuna steaks, it's important to follow a few guidelines to ensure food safety and optimal flavour. Firstly, the acid in the marinade can "cook" the tuna, altering its texture and flavour, so it's best to limit the marinating time for tuna steaks to 30 minutes to 2 hours.

For a simple marinade, a mixture of oil, honey, garlic, cumin, parsley, salt, pepper, and lemon juice can be prepared. This combination of ingredients provides a balance of sweet, savoury, and acidic flavours that complement the tuna.

After whisking the ingredients together, place the tuna steaks in the marinade and turn them over to ensure they are fully coated. Cover the dish with plastic wrap and marinate in the refrigerator for at least 30 minutes but no longer than 2 hours.

If you're looking for a shorter marination time, some recipes suggest a minimum of 10 minutes or even as little as 6 minutes of marination for a quick and easy meal. However, allowing the tuna to absorb the flavours for a longer period within the recommended time frame will enhance the taste.

Once the tuna has finished marinating, gently pat it with paper towels to remove the excess marinade, and it will be ready for cooking.

Pan temperature: hot pan, medium heat

When cooking marinated tuna steaks, it's important to get the pan to the right temperature to ensure a good sear and avoid the marinade burning. Here's a step-by-step guide to achieving a "hot pan, medium heat":

Firstly, use a medium skillet, preferably non-stick or a well-seasoned cast-iron skillet. Heat the pan on medium-high to high heat until very hot—this should take around 3-5 minutes for cast iron and 1 minute for non-stick. You want the pan to be hot enough to create a perfect sear, but not so hot that your marinade burns.

Once your pan is hot, add your oil of choice—typically, 1-2 tablespoons of oil is sufficient. You can use avocado oil, olive oil, or sesame oil, depending on your preference.

Now it's time to sear your tuna steaks. Place the steaks carefully into the hot pan and sear for 1-1.5 minutes per side, using a flat steel spatula to flip them carefully. The exact cooking time will depend on the thickness of your steaks; for steaks less than 1.5 inches thick, sear for just 1 minute on each side.

Finally, transfer your seared tuna steaks to a large cutting board and let them rest for about 5 minutes before slicing and serving.

By following these steps, you'll achieve a nice sear on your marinated tuna steaks while avoiding burning the marinade, resulting in a delicious and visually appealing dish.

Cooking time: 1.5 minutes per side, 1 minute if <1.5 inches thick

When cooking tuna steaks, it's important to remember that the thickness of the tuna steak will impact the cooking time. If your tuna steak is less than 1.5 inches thick, sear for only 1 minute on each side. For thicker cuts of tuna, searing for 1.5 minutes per side will ensure a nice crust forms while keeping the inside of the tuna steak rare.

Tuna steaks are best served rare to medium-rare. If you prefer your tuna steak well done, you will need only a minute or two more on each side, depending on thickness. Be sure not to overcook it, as this will dry out the tuna and negatively impact its flavour and texture.

Tuna steaks are a versatile dish that can be served warm or cold. They pair well with a variety of side dishes, including salads, rice, noodles, and grilled vegetables. For a more substantial meal, try serving your tuna steak with roasted or grilled vegetables and rice, drizzled with a sauce such as sesame-tamari or spicy mayonnaise.

To add even more flavour to your dish, consider topping your tuna steak with sautéed mushrooms or crispy garlic broccoli.

Serving suggestions: side salad, rice, noodles, roasted veggies, or sauce for dipping

Serving suggestions

Side salad

A tuna steak pairs well with a refreshing salad. A salad with greens, cucumber, avocado, and scallions can be topped with grilled tuna steak. You can also add a punchy wasabi vinaigrette to the salad.

Rice

Day-old rice is ideal for pan-fried crispy rice. You can prepare it in the same skillet as the tuna. Heat some butter in a pan, add chopped garlic and brown, then add the rice and break up any clumps. Coat the rice with the garlic butter, then add salt and pepper to taste.

Noodles

Tuna steaks go well with noodles. Boil the noodles for 3 minutes, drain the water, and stir-fry with sesame oil and ginger. Add spring greens and stir fry for 2 minutes before tossing in the noodles. Add soy sauce and stir well.

Roasted veggies

Roasted veggies are a great side dish for tuna steaks. Carrots, potatoes, and broccoli are some vegetables that can be roasted in the oven.

Sauce for dipping

A dipping sauce can be made by mixing mayonnaise, sugar, vinegar, soy sauce, garlic, ginger, sesame oil, pepper, and cayenne.
