Step 1
Blanch aji amarillo chiles in boiling water for 2 minutes until soft. Drain and cool slightly.
Step 2
Blend softened aji with lime juice, 1 tbsp olive oil, soy sauce, and 1 minced garlic clove until smooth.
Step 3
Strain sauce through a fine sieve if you prefer silky texture; press solids gently. Chill.
Step 4
Heat 2 tbsp olive oil in a 10-inch skillet over high heat until it shimmers, ~90 seconds.
Step 5
Thinly slice remaining garlic. When oil is hot, cook garlic until golden and crispy, ~2 minutes. Transfer to paper towel.
Step 6
Pat tuna completely dry. Season generously with salt and black pepper on all sides.
Step 7
Sear tuna 60 seconds per side without moving. Edges should look opaque; center stays rare.
Step 8
Transfer tuna to cutting board. Let rest 2 minutes, then slice into 1/4-inch-thick pieces.
Step 9
Arrange tuna slices on a chilled plate. Drizzle aji sauce around and over the top.
Step 10
Scatter crispy garlic chips and a squeeze of lime juice over tuna. Serve immediately.
