Seared Ahi Tuna Bowl

A nutritious, high-protein bowl that is full of flavors!

Calling all sushi and poke lovers, this is the ultimate dish for you! Seared ahi tuna with fresh vegetables and fruits over rice is a protein-packed, gluten-free meal* that will satisfy your cravings. A homemade ponzu (Japanese citrus sauce) is drizzled on top to bring all the flavors together.

I have always loved sashimi growing up, however, sushi, poke, or any raw fish meal is quite expensive outside home. Purchasing a good quality fish is also expensive, but you get more bang for your buck when you make such dishes from scratch. I recently purchased a wholesale pack of ahi tuna steaks and have been enjoying a variety of tuna dishes, meaning you can expect a few more tuna recipes after this initial one! For this recipe, I kept it very simple and enjoyed a seared rare tuna steak. Tuna is mostly eaten raw or semi-raw because thoroughly cooked tuna is quite dry, due to its low fat content. A well-done tuna steak would be similar to canned tuna, and that’s just not what we are achieving here.

How to purchase safe tuna?

Consuming raw fish will always come with risks. High-risk individuals should not consume it. Be cautious of your tuna’s source and make sure you are purchasing sashimi-grade fish. Sashimi-grade is an unofficial term which means the seller states that the fish is safe for raw consumption, based on FDA guidelines. The fish should be frozen for a certain amount of time right after it is caught to kill any parasites. Wild fish is more likely to have parasites than farmed fish. The best tips to purchasing a fish that is to be eaten raw is to buy from a reliable source and read reviews. I did plenty of research on my supplier before purchasing the tuna from them.

How to prepare ahi tuna at home: If the tuna steak arrives frozen, thaw it in the fridge and eat within 24 hours of thawing. Sanitize cutting boards and knives with boiled waiter.

Ingredients and nutrition benefits:

Tuna is a lower calorie, high protein fish that is rich in B vitamins and potassium. I accompanied the tuna rice with carrots, edamame, pineapples, cucumber, and avocado for color and nutrient variety. Adding more colors=adding a wider variety or vitamins and minerals. These ingredients are all low fat (with the exception of avocado, which contains healthy fats), but very satiating!
