Orange Marinated Ahi Tuna Tacos with Avocado Sauce

It’s almost summer, and I will be celebrating the season here on Bluberry Pancakes Forever!! I’m getting started early with these fresh summer-like Ahi Tuna Tacos. Living in Austin for 10 years influenced my cooking style in a huge way, and I’m bringing that (healthy) southern style to my home here in the midwest. My fave tacos to order at any Austin restaurant are fish tacos, and believe me there is an endless supply of delicious tacos to choose from in that city.

I want to share some of that special “Austin” flare with all of you with these Ahi Tuna tacos!

I have been experimenting with making my own corn tortillas, and it’s been going surprisingly well! I don’t have a tortilla press, so my tortillas have been coming out in all kinds of weird shapes. My solution has been to use a 5in or 6in bowl to cut them into perfect circles. Now, of course if you don’t have the time you can skip this step and purchase your favorite corn tortillas.

Corn Tortillas

I love fruit and fish combos! Personally I always feel like I’m being swept away to the beach when I bite into a fish taco topped with mango salsa. For this recipe I experimented with an orange and brown sugar marinade – it turned out wonderfully, and the avocado sauce balances out the sweetness of the marinade.

Tuna Tacos & Tortillas

A few tips/notes:

I like my tuna cooked medium-well, but you can cook it to your liking!

I have found that rolling the tortillas a little thicker will hold the fish and other toppings without cracking the tortilla.

I let the fish marinade in the fridge for about 1.5hrs before broiling, and with about 1-2 mins left of broiling time I sprinkle with just a little more brown sugar. So good!!

Hope you enjoy these tasty tacos – Happy Summer!
