Seared Ahi Tuna is seriously one of my fav dishes and one of those meals that tastes like restaurant quality with minimal effort. After all, the whole recipe is done in under 10 minutes! It’s a great dish to serve in the summer and winter, because it’s fresh and light, but super meaty and filling at the same time. It’s also so versatile when it comes to pairings – I like mine on a hot bed of rice with veggies in the colder months, and on a fresh salad in the spring/summer. Tuna is super healthy as it’s a lean meat and a great source of omega 3 fatty acids.

For this recipe, I used 2 tuna steaks which was good for 3 people. Pro tip: slicing your steak goes a long way!

I hope you like this recipe as much as I do!
