Tuna steaks are one of my favorite foods ever. So good. However, I went years without buying them because they are expensive. They would always be the first thing I looked for on restaurant menus because it was something I never made at home. My grocery budget just couldn't accommodate it. But a few months ago while walking around Sam's Club, I noticed some Ahi tuna steaks in the freezer section. I looked at the price, then I looked at how many pounds were in the bag, and I got excited. Still definitely not the cheapest thing to buy, but definitely doable. So we now have tuna steaks every two or three weeks.
There are lots of fun things to do with tuna steaks, but this marinade is the simplest and best. The orange, soy, ginger, and garlic flavors are perfect on tuna. This marinade allows you to cook the tuna any way you like: grill, pan-sear, bake, or any other way you can think of, with perfect results every time. It's adapted from one I saw on Allrecipes.
Orange Soy Tuna Steak Marinade
¼ cup orange juice
¼ cup reduced-sodium soy sauce
2 tbsp olive oil
1 tbsp white wine vinegar
1 tsp powdered ginger
½ tsp garlic powder
4 tuna steaks
Pour all ingredients in a gallon-sized Ziploc bag. Smoosh to mix. Add tuna steaks and seal. Marinate for 1-2 hours. Remove tuna from bag and discard remaining marinade. Cook tuna as desired.
So simple, but so good. My favorite way to cook the tuna is grilling, as you can see above, but when it gets too cold to grill I will switch to pan searing.
I have served this tuna with rice, peanut noodles, and most recently with a Thai Veggie Couscous (in the pic above). It's very versatile.
