How To Cook Costco Tuna: The Quick Version
To cook Costco tuna steaks, particularly yellowfin or ahi tuna, you can follow these simple methods that highlight the fish’s natural flavor while ensuring a delicious result.
Basic Preparation Steps
- Thaw the Tuna Steaks: If frozen, thaw the tuna steaks in the refrigerator for several hours or overnight.
- Marinate (Optional): For added flavor, consider marinating the tuna. A simple marinade could include:
- 2 tablespoons soy sauce
- 1 tablespoon toasted sesame oil
- 1 tablespoon honey
- 1/2 teaspoon kosher salt
- 1/4 teaspoon black pepper
- 1/4 teaspoon cayenne pepper (optional)
Marinate for about 30 minutes before cooking to allow the flavors to penetrate the fish.
Cooking Methods
Pan-Seared Tuna
- Prepare the Pan: Heat a cast iron skillet or non-stick pan over high heat. Add a neutral oil (like canola or vegetable oil) with a high smoke point.
- Sear the Tuna: Once the oil is shimmering, add the tuna steaks. Sear for about 1-2 minutes on each side, depending on the thickness of the steaks. The goal is to achieve a nice crust while keeping the inside rare to medium-rare.
- Serve: Once cooked, remove from the pan and let rest for a minute. Slice and serve with a sprinkle of sesame seeds or alongside a salad or rice.
Alternative Cooking Ideas
- Sesame-Crusted Tuna: Before searing, coat the tuna in a mixture of black and white sesame seeds for added texture and flavor. Sear as described above.
- Grilled Tuna: If you prefer grilling, preheat your grill and lightly oil the grates. Grill the tuna steaks for about 2-3 minutes per side, ensuring to watch for flare-ups due to the oil.
- Air Fryer Tuna: For an air fryer method, preheat the air fryer to 400°F (200°C). Lightly oil the tuna and season as desired. Cook for about 6-8 minutes, flipping halfway through, for a deliciously cooked steak.
Serving Suggestions
Tuna pairs well with various sides. Consider serving it with:
- A cucumber salad
- Sticky rice
- A drizzle of basil pesto for a unique twist.
These methods will help you enjoy Costco tuna steaks simply and deliciously, highlighting their fresh flavor.
