How To Make Yuzu Ahi Tuna Appetizer with Potato

Step 1. 

Make the sweet potato crisps. Peel and thinly slice the Japanese sweet potato, about ¼ inch thick. In a stainless steel or cast iron pan, heat the ghee or avocado oil over medium-high heat until it starts to smoke or ripples. Place the Japanese sweet potato slices in a single layer, taking care not to overcrowd the pan. Cook for 1-2 minutes on each side being careful not to burn. Remove and set aside. 

Step 2. 

Season and sear the ahi tuna. Season the tuna with salt and pepper. Coat tuna in yuzu furikake, coating evenly. In a non-stick pan, heat the ghee or avocado oil over medium-high heat until it starts to smoke or ripples. Place the tuna in the pan and cook for about a minute. The white sesame seeds start to turn golden brown. Carefully turn the tuna over and cook for about another minute, checking after 45 seconds. Transfer the tuna to a cutting board and cut into 1/4 inch thick slices.

Step 3. 

Make the yuzu mayo. Mix in a bowl to combine. Transfer to a squeeze bottle until ready to serve.

Step 4.

Assemble the tuna & potato crisps. Arrange potato crisps in a single layer and place a piece of tuna on each potato crisps. Using a squeeze bottle, drizzle yuzu mayo over each tuna topped potato crisp. Transfer to a serving platter and garnish with fresh parsley, cilantro, or micro green. Serve immediately. 

Recipe Tips

Make sure you are using ghee or avocado oil in this recipe as it has a high smoke point and will sear the tuna and potato in the correct way. 

This appetizer must be served immediately, but the yuzu mayo can be made ahead of time. 

You can purchase Whole30 Compliant Mayo, or you can make your own at home. 

Add your mayo to a Squeeze Bottle for garnishing the tuna with mayo.
