Black and Blue Ahi Tuna: A Culinary Adventure

The first time I tasted seared ahi tuna, I was dining at a tiny bistro overlooking the Pacific. The salty air, the crash of the waves, and the perfectly seared tuna with its vibrant spices—it was an experience that sparked my love affair with this versatile fish. The contrast between the peppery crust and the melt-in-your-mouth interior was simply divine. I was inspired to try and recreate the dish, and after many trials and adjustments, I found a way to bring those bold flavors into my own kitchen. This Black and Blue Ahi Tuna recipe isn’t just a meal; it’s a journey for your taste buds.

• Dietary Type: Pescatarian

Ingredients

For the Tuna:

• 4 tuna steaks
• ½ tablespoon cumin
• 1 tablespoon oregano
• 1 tablespoon thyme
• 1 tablespoon dry mustard
• 1 tablespoon cayenne
• 1 tablespoon black pepper
• 1 tablespoon paprika
• Olive oil (for searing)

For the Mustard Sauce:

• 6 ounces Grey Poupon Dijon Mustard
• ¾ cup soy sauce
• ¼ tablespoon dry mustard

For the Vegetables:

• 1 green bell pepper, julienned
• 1 red bell pepper, julienned
• 1 small onion, sliced thin
• 1 teaspoon oregano
• ½ teaspoon pepper
• ½ teaspoon salt
• 3 tablespoons olive oil

Equipment Needed

• Small bowl
• Saucepan
• Skillet
• Whisk

Instructions

1. Begin by preparing the vegetables. Heat 3 tablespoons of olive oil in a saucepan over medium heat. Add the julienned green and red bell peppers and thinly sliced onion. Season with 1 teaspoon of oregano, ½ teaspoon of pepper, and ½ teaspoon of salt. Sauté the vegetables until they are tender-crisp, approximately 7 minutes. Keep warm.
2. Next, prepare the tuna spice rub. In a small bowl, combine ½ tablespoon of cumin, 1 tablespoon of oregano, 1 tablespoon of thyme, 1 tablespoon of dry mustard, 1 tablespoon of cayenne, 1 tablespoon of black pepper, and 1 tablespoon of paprika.
3. Generously season all sides of the tuna steaks with the prepared spice rub. Ensure an even coating for maximum flavor.
4. Prepare the mustard sauce. In a bowl, whisk together 6 ounces of Grey Poupon Dijon Mustard, ¾ cup of soy sauce, and ¼ tablespoon of dry mustard until well combined. Set aside.
5. Heat a skillet over high heat. Add a drizzle of olive oil. Once the skillet is smoking hot, carefully place the seasoned tuna steaks in the skillet.
6. Sear the tuna steaks for approximately 2 minutes per side for rare, or longer depending on your desired level of doneness. For a true “black and blue” effect, aim for a dark crust on the outside while keeping the center rare.
7. Remove the seared tuna steaks from the skillet and let them rest for a minute or two before slicing.
8. To serve, slice the tuna steaks thinly, about ¼ inch thick. Arrange the slices on a plate and top with the sautéed vegetables and a generous drizzle of the mustard sauce. Serve immediately.

Expert Tips & Tricks

• For an extra layer of flavor, consider adding a pinch of smoked paprika to the spice rub.
• Don’t overcrowd the pan when searing the tuna; sear in batches if necessary to maintain high heat.
• To check the doneness of the tuna, gently press the center with your finger. Rare tuna will feel soft, while medium will be slightly firmer.
• If you prefer a milder flavor, reduce the amount of cayenne pepper in the spice rub.
• The mustard sauce can be made ahead of time and stored in the refrigerator for up to 3 days.

Serving & Storage Suggestions

Serve the Black and Blue Ahi Tuna immediately for the best flavor and texture. Garnish with a sprinkle of fresh parsley or a wedge of lemon for added visual appeal.

Leftover sliced tuna can be stored in an airtight container in the refrigerator for up to 24 hours. While the seared crust will soften, it can still be enjoyed cold in salads or sandwiches. Due to the nature of the dish, freezing is not recommended.
