This fast, healthy, and delicious seared tuna dish comes together in one pan and is ready in less than 30 minutes. Serve with a mixture of seasoned cucumbers, tomatoes, and red onion for a light and refreshing meal.
When buying tuna steaks, look for firm, dense red or dark red flesh. Tuna has a meaty firm flesh and a rich, strong flavour due to its high oil content. It can spoil very quickly, so when buying, use it as soon as possible after purchase for the very best results in your cooking.
Tuna steaks are easy to prepare and fast to cook. They are usually sold skinned, boned and cut into portions, so there is minimal prep work to do.
Tuna can dry out quickly when cooking, so be very mindful of that. In this pan-seared tuna steaks recipe, they are cooked for just a couple of minutes each side. Tuna can be served pink in the middle, which in my opinion the best way to enjoy it!

Tuna
Tuna is a saltwater fish, found in warm seas and depending on the species can grow to over 6 feet. It is one of the fastest fish in the ocean – the yellowfin tuna can reach speeds of nearly 50 mph!
Tuna it is extensively fished commercially, and is popular as a game fish. As a result of overfishing, some tuna species, such as the southern bluefin tuna, are threatened with extinction.

Recipes on The Purple Pumpkin Blog use both cup measurements and/or weighted measurements. American cups and kitchen food scales are handy pieces of equipment to have in your kitchen as it means you’ll be able to make all of the different recipes on my blog. I try to give American, imperial, and metric measurements in my recipes. You can mix cup measurements with weighted measurements, but never mix imperial (pounds, ounces, pints, etc.,) with metric (kilograms, grams, litres, etc.,).
