What are the main ingredients for tuna steak?
Hereβs the list of ingredients used in this seared tuna steak recipe:
- Tuna Steak: This is the star ingredient of the dish. Fresh Ahi-tuna or Yellowfin tuna is a lean and protein-rich fish that is firm and meaty in texture, making it a great base for searing.
- Soy sauce: Soy sauce is an excellent addition to this dish as it provides a savory and umami flavor that pairs well with the tuna.
- Sesame Seeds: These small seeds are commonly used in Asian cuisine and provide a nutty and aromatic flavor. They also add a pleasing crunch to the tuna crust.
- Granulated Garlic: This is garlic that has been dried and ground into a fine powder. It has a pungent and savory flavor that adds depth to the crust.
- Sugar: Sugar adds a touch of sweetness to the crust and helps to caramelize the exterior of the tuna steak during the searing process.
- Oregano: This herb has a slightly earthy and herbaceous flavor that complements the other ingredients in the crust. It also adds a touch of freshness to the dish.
- Salt and Black Pepper: These common seasonings are used to season the tuna steak before searing, enhancing its natural flavor.
- Oil: Vegetable or sesame oil may be used to coat the skillet or grill before cooking the tuna steak. This helps to prevent sticking.

- High in protein: Tuna steak is a good source of high-quality protein (19g per 100g), which is essential for building and repairing muscles and tissues.

Should I wash tuna steak before cooking?
It is generally not recommended to wash tuna steak before cooking it. Washing the tuna steak can actually increase the risk of cross-contamination and spread harmful bacteria, as water can splash and spread germs onto other surfaces in the kitchen. Tuna steak is typically sold fresh and has already been cleaned and prepared by the fishmonger or vendor. Before cooking the tuna, itβs a good idea to pat it dry with a paper towel to remove any excess moisture. This will help the tuna sear properly and prevent it from sticking to the skillet or grill.

How to make Seared Tuna Steak?
In a small bowl, mix together the soy sauce and oil. Brush the mixture onto both sides of the tuna steaks and let them marinate for 10 minutes.
In another bowl, mix together the sesame seeds, granulated garlic, sugar, oregano and black pepper.
Coat the tuna steaks with the sesame seed mixture, ensuring it is evenly covered. Heat a skillet or grill over medium-high heat. Add a bit of oil to the skillet or grill to prevent sticking. Once the skillet or grill is hot, add the tuna steaks and sear for 1,5β2 minutes on each side, or until the sesame seed crust is golden brown and the tuna is cooked to your desired level of doneness.
Remove the tuna steaks from the skillet or grill and let them rest for a few minutes before slicing and serving.
This dish is delicious when served with a side of stir-fried vegetables or a simple salad. Drizzle a bit of soy sauce over the top of the tuna steaks or serve it as a dipping sauce on the side. Enjoy!

How long does it take to sear tuna?
The cooking time for seared tuna will vary depending on the thickness of the tuna steak and the desired level of doneness. As a general rule of thumb, seared tuna should be cooked for about 1β2 minutes per side for rare, 2β3 minutes per side for medium-rare, and 3β4 minutes per side for medium.
However, itβs important to keep a close eye on the tuna while itβs cooking, as overcooking can result in dry and tough tuna.
When searing tuna, itβs also important to ensure that the skillet or grill is hot enough before adding the tuna. The skillet or grill should be preheated over medium-high heat for several minutes before adding the tuna to ensure that it sears properly.

Frequently Asked Questions
What type of tuna is best for searing?
Sushi-grade ahi (yellowfin) tuna is the gold standard for seared tuna steaks. Look for deep red, firm steaks with no brown discoloration or fishy smell. Since the center stays rare, purchasing from a reputable fishmonger who sells sushi-grade fish is essential for both safety and flavor.
How do I keep the center of the tuna rare while getting a good sear?
The key is an extremely hot skillet and a very short cooking time β just 1.5 to 2 minutes per side. Make sure the tuna is patted dry and the pan is screaming hot before adding the fish. Do not move the steak while it sears, as this interrupts the crust formation.
Can I eat seared tuna steak the next day?
Yes, leftover seared tuna can be refrigerated in an airtight container for up to 2 days. It is best enjoyed cold or at room temperature β sliced thin over a salad or in a rice bowl. Reheating is not recommended as it will cook through the rare center and change the texture entirely.
What can I use instead of sesame seeds for the crust?
Black sesame seeds add a dramatic visual contrast while keeping a similar flavor. You can also try a mix of crushed peppercorns and coriander seeds, or finely chopped macadamia nuts for a richer, nuttier crust. For a nut-free and seed-free option, panko breadcrumbs seasoned with the same spices work well.
