Japanese Crispy Tuna Steaks with Stir-Fried Green Beans

Sauce

• ½ cup aquafaba mayonnaise (I like Sir Kensington’s) or regular mayonnaise
• 2 tbsp. Dijon mustard
• 1 tbsp. soy sauce, shoyu, or tamari
• 1 tbsp. sriracha
• 1 tsp. fresh lime juice
• 1 tsp. ground ginger
• 1 clove garlic, grated or pasted

Green Beans & Crispy Tuna

• Salt
• 1 lb. trimmed green beans or haricots verts (small green beans)
• 1 cup plain breadcrumbs
• ½ cup panko breadcrumbs
• 3 tbsp. white or black sesame seeds
• 1 tsp. chili powder or crushed red pepper
• 1 tsp. granulated garlic
• 1 tsp. granulated onion
• 1 tsp. ground ginger
• 4 sushi-grade tuna steaks (each 6 to 8 oz. and about 1 1/4 inches thick)
• About 1/4 cup plus 3 tbsp. safflower, peanut, or canola oil
• 6 scallions, cut on an angle into 2-inch pieces
• 3 tbsp. soy sauce, shoyu, or tamari
• 2 tbsp. mirin or rice wine vinegar
• 2 tsp. toasted sesame oil
• Pepper
• Finely chopped chives, for garnish

Step 1

In a small bowl, whisk all the ingredients for the sauce.

Step 2

For the green beans, in a large deep skillet, bring a few inches of water to a boil. Prepare a large bowl of ice water. Salt the boiling water and add the green beans. Cook until crisp-tender, about 3 minutes. Drain the green beans and add to the ice water. Let cool, then drain well.

Step 3

Heat a large cast-iron skillet over medium to medium-high.

Step 4

In a shallow dish, mix the plain breadcrumbs, panko, sesame seeds, chili powder, granulated garlic, granulated onion, and ground ginger.

Step 5

Season both sides of the tuna with salt. Coat the tuna with the breadcrumbs, pressing firmly so the crumbs adhere.

Step 6

Add enough safflower oil to the skillet to coat the bottom (about 1/4 cup). When the oil begins to ripple, add the tuna. Cook until deep golden, about 3 minutes per side. Transfer to a wire rack.

Step 7

Meanwhile, in a large nonstick skillet, heat the remaining 3 tbsp. safflower oil, three turns of the pan, over high. When the oil begins to smoke, add the green beans and scallions. Stir-fry until the green beans blister, about 3 minutes. Add the soy sauce, mirin, and sesame oil; season with salt and pepper.

Step 8

Serve the crispy tuna on top of the sauce. Or top the tuna with the sauce. Garnish with chives. Serve with the green beans.
