Ingredients
2 tuna steaks
1 head cauliflower, cut into florets
1 cup cooked quinoa (prepared according to package directions)
1 teaspoon olive oil
1/4 cup shredded Parmesan cheese
1 teaspoon salt, divided
1 tablespoon salted butter
Directions
Prepare the quinoa according to package instructions and set aside to cool slightly.
Bring a large pot of water to a boil. Add the cauliflower florets and simmer for 8 minutes until very tender.
Drain the cooked cauliflower thoroughly. Transfer to a food processor and add the butter, Parmesan cheese, and 1/2 teaspoon of salt. Blend until smooth and creamy. Adjust seasoning if needed.
Season both sides of each tuna steak evenly with the remaining 1/2 teaspoon of salt.
Place the cooled cooked quinoa on a shallow plate. Press each side of the tuna steaks firmly into the quinoa, coating generously so the grains adhere to the fish.
Heat the olive oil in a large skillet over medium heat until shimmering. Carefully place the quinoa-coated tuna steaks into the skillet, quinoa-side down, and sear for 1 minute without moving.
Flip the tuna steaks carefully and sear the other quinoa-coated side for 1 minute. The tuna should reach an internal temperature of 145°F. Some quinoa grains may fall off during searing, which is normal.
Spoon the cauliflower puree onto serving plates. Top each with a seared tuna steak and serve immediately.
Comments
Quinoa and fresh tuna are both reliably stocked at Harris Teeter, Food Lion, and Walmart around Charlotte, and cauliflower is a year-round staple; this recipe clears ingredient availability with no special stops. The cost per serving lands around $8–$10 depending on tuna quality, which is reasonable for a seafood dish but not budget-friendly for weeknight rotation. The stated 25 minutes is optimistic—cauliflower puree requires simmering and blending, and searing tuna to the right doneness takes precision, so budget 35–40 minutes with focused attention. This works well for two people or as a dinner-for-two showpiece, but the tuna's short window between undercooked and overdone means it's not forgiving for a distracted cook or a table that eats at staggered times.
