Ingredients You’ll Need

Sweet Potato Crisps

  • Japanese Sweet Potato – This perfectly slightly sweet and starchy potato makes a great base for the tuna. 
  • Ghee – The potato gets pan fried in ghee to make a crust that keeps it tender on the inside. You can also use avocado oil. 
  • Salt – Helps to enhance the flavor of the sweet potato. 

Yuzu Ahi Tuna

  • Ahi Tuna – The perfect high protein tuna that soaks up flavor well. 
  • Yuzu Furikake – This furikake flavoring has added yuzu fruit flavor for a pop of citrus taste.
  • Salt & Pepper – Helps to balance and enhance the flavor of the tuna. 
  • Garnish – Top the appetizer with fresh parsley, cilantro, or micro greens.

Yuzu Mayo

  • Whole30 Compliant Mayo – Makes up the creamy base of this condiment. 
  • Yuzu Juice & Kosho Paste – Adds bright, citrusy yuzu flavor to the mayo. 

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.
