Sesame and Wasabi Crusted Tuna With Roasted Asparagus

There’s something incredibly satisfying about the vibrant colors and bold flavors of Asian-inspired cuisine. I remember one summer evening in San Diego, dining al fresco with the salty ocean breeze, when I first tasted a dish similar to this one. The perfectly seared tuna, the gentle heat of wasabi, and the crisp-tender asparagus created a symphony of textures and tastes that danced on my palate. Ever since, I’ve been experimenting with recreating that experience, and this recipe comes pretty darn close.

Recipe Overview

• Prep Time: 10 minutes
• Cook Time: 15 minutes
• Total Time: 25 minutes
• Servings: 4
• Dietary Type: Pescatarian

Ingredients

• 1 lb fresh ahi tuna
• 1 lb asparagus
• ½ cup sesame seeds
• ½ cup wasabi peas
• 1 tablespoon coconut oil
• 1 cup soy sauce
• 2 tablespoons brown sugar

Equipment Needed

• Baking pan
• Saucepan
• Frying pan
• Plate (for coating)

Instructions

1. Preheat your oven to 400 degrees Fahrenheit.
2. Arrange the asparagus in a single layer on a greased baking pan. Roast for approximately 20 minutes, or until tender-crisp. A quick spray with cooking spray (like Pam) before roasting helps prevent sticking.
3. While the asparagus roasts, prepare the soy reduction. In a saucepan, combine the soy sauce and brown sugar. Cook over low heat, stirring frequently, until the sauce reduces and thickens to a glaze-like consistency. This usually takes about 5-7 minutes. Set aside. The sauce should coat the back of a spoon.
4. Heat the coconut oil in a frying pan over medium-medium high heat. Ensure the pan is hot before adding the tuna for a good sear.
5. Crush the wasabi peas. You can do this easily by placing them in a ziplock bag and crushing them with a rolling pin or the bottom of a pan.
6. On a plate, mix the crushed wasabi peas with the sesame seeds.
7. Thoroughly coat the ahi tuna in the wasabi-sesame seed mixture, pressing gently to ensure the crust adheres.
8. Carefully place the crusted tuna in the hot oil and sear for approximately 2 minutes on each side for rare to medium-rare. Adjust the cooking time to your preference; for medium, cook for about 3 minutes per side. The internal temperature should reach 125-130°F for rare to medium-rare. Avoid overcooking the tuna, as it will become dry and tough.
9. Remove the tuna from the pan and let it rest for a couple of minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful piece of fish.
10. Slice the tuna into medallions.
11. Arrange the sliced tuna on a plate with the roasted asparagus.
12. Drizzle the soy reduction generously over the tuna and asparagus. Serve immediately.

Expert Tips & Tricks

• High-Quality Tuna is Key: Use the freshest, highest-quality ahi tuna you can find. Look for tuna that is vibrant in color and has a firm texture.
• Don’t Overcook the Tuna: Ahi tuna is best served rare to medium-rare. Overcooking will make it dry and less flavorful. Use a meat thermometer to ensure you reach your desired level of doneness.
• Spice it Up: If you want a bit more heat, add a pinch of red pepper flakes to the wasabi-sesame seed mixture.
• Soy Reduction Thickness: The soy reduction should be thick enough to coat the tuna and asparagus nicely. If it’s too thin, continue to simmer it until it reaches the desired consistency.
• Asparagus Prep: Snap off the tough ends of the asparagus before roasting.

Serving & Storage Suggestions

Serve the Sesame and Wasabi Crusted Tuna with Roasted Asparagus immediately for the best flavor and texture. Garnish with a sprinkle of sesame seeds and a few sprigs of fresh cilantro for added visual appeal. This dish pairs well with coconut cilantro rice.

Leftovers can be stored in an airtight container in the refrigerator for up to 24 hours. However, the tuna is best consumed fresh. The asparagus may become slightly softer upon reheating. Reheat gently in a pan over low heat or in the microwave. The tuna is generally not recommended for freezing due to texture changes.

• Sweetener: Honey can be used in place of brown sugar for a different flavor profile in the soy reduction.

FAQs (Frequently Asked Questions)
