Making this seared tuna steak recipe
This seared tuna steak recipe is one of those ideal weeknight dinners. I know I’ve probably said it a thousand times before, but I am a huge fan of single pan meals. This recipe uses only one pan to make everything which is a win in my opinion. Plus, it’s keto friendly, gluten-free, and only takes 30 minutes to make!

Before you get to frying, though, you’ll want to rinse the steaks in cold water and pat dry. Then heat your pan with two tablespoons of olive oil on medium-high heat. Make sure your oil is hot before you place the steaks inside the pan (this is especially important if you’re looking to do a nice outside sear with the inside more on the rare side).
How long should you cook your tuna steaks?
When it comes to cooking the tuna steaks, it’s really a personal preference. In my household, we love the seared outside and rare inside. This takes about four minutes total. However, if you’re uncomfortable with raw fish add another minute on each side to get a more medium-well cook. Another option is to check the internal temperature to make sure it’s cooked the way you want it (140-145 degrees for more well done and 125 degrees for a rare inside).
Making the lemon-caper sauce
Once the steaks are done, remove them from the pan but keep them warm. Add the rest of the olive oil and the chopped shallots into the pan and cook them till they are soft and are beginning to brown. Add the rest of the ingredients (except the capers) and cook until the liquid has been reduced to half the amount.

Finally, add your capers and let them cook for a minute before removing the sauce off the heat. Plate the tuna steaks and top with a slice of lemon and the caper sauce!
