This is one of my favorite weeknight dinners because it comes together in just 27 minutes from start to table. Fresh ahi tuna is a fantastic source of omega 3 fatty acids, which are wonderful for heart health, and it pairs beautifully with garlicky sautéed spinach. The best part? You probably have most of these ingredients already in your kitchen. The tuna develops a perfect crust on the grill while staying tender inside, and the bright lemon and capers cut through the richness perfectly. It's elegant enough for company but simple enough for a regular Tuesday night.

Instructions
- 1
Pat tuna steaks dry with paper towels and season both sides generously with salt, pepper, and red pepper flakes. Let sit at room temperature for 10 minutes before cooking.
Tip: Drying the tuna ensures better browning and a nice crust.
- 2
Heat 1 tablespoon of olive oil in a large cast iron skillet over high heat until shimmering and nearly smoking.
Tip: A very hot pan is crucial for getting a seared crust while keeping the inside rare to medium-rare.
- 3
Sear the tuna steaks for 2-3 minutes per side, depending on thickness and desired doneness. Transfer to a warm plate and tent loosely with foil.
Tip: For medium-rare centers, aim for 3 minutes per side. Ahi tuna is best served rare to medium-rare.
- 4
In the same skillet, add 2 tablespoons of olive oil and sauté minced garlic for 30 seconds until fragrant.
Tip: Don't let the garlic burn; it will become bitter.
- 5
Add the fresh spinach in batches, stirring constantly for 2-3 minutes until completely wilted and any excess moisture has evaporated.
Tip: Working in batches prevents the spinach from steaming instead of wilting.
- 6
Stir in lemon juice, capers, and the remaining 1 tablespoon of olive oil. Season with salt and pepper to taste. Remove from heat and drizzle with sesame oil.
Tip: The capers add a briny, acidic element that complements the rich tuna beautifully.
- 7
Divide the spinach mixture among four plates and top each with a tuna steak. Sprinkle with fresh lemon zest before serving.
Tip: Serve immediately while the tuna is still warm and the spinach is at its best.
