Golden Peruvian Causa with Avocado & Tuna – A Stunning Summer Dinner

Let me introduce you to a show-stopping dish from Peru that brings sunshine to your table: Peruvian Causa Dinner Potatoes and Tuna. Causa, a beloved classic in Peruvian cuisine, is often served as an appetizer, but this elegant layered creation also makes a substantial, refreshing summer dinner. Served cold, it is ideal for warm days when you crave something hearty yet light.
Causa is traditionally made with Peruvian yellow potatoes, which have a buttery texture and sunny color. They’re mashed and seasoned with olive oil and aji amarillo paste, giving them a mild heat and golden hue. The potato layers are stacked with creamy avocado slices and a zesty tuna salad. In this recipe, I use Wild Planet Albacore Solid White Tuna in Extra Virgin Olive Oil, combined with capers, purple onion, chopped boiled eggs, sweet pepper, pickles, and a touch of mayonnaise for richness.
What sets this dish apart is not only its balance of textures and flavors but also its stunning visual presentation. Each portion is artfully molded and garnished with vibrant elements: cucumber slices, tomato wedges, hard-boiled egg rings, olives, roasted red pepper strips, and fresh herbs like mint and cilantro. It becomes a canvas for your creativity.
I recommend preparing and assembling it a day ahead to allow the flavors to meld and to simplify your serving routine. While many causa recipes yield small portions, I’ve scaled this one to fit a 4¾-inch glass dish, making two generous servings. Whether you serve it at a garden dinner, brunch, or picnic, this dish never fails to impress.
