A Chicago Classic Brought Home
My first encounter with the Buona Beef Tuna Genovese copycat recipe goes back to a chilly Chicago night. While everyone at the table leaned toward the Italian beef, I decided to try the Tuna Genovese. That sandwich became unforgettable—the warm onions, tender tuna, and rich Genovese-style sauce all came together in a way that felt both comforting and bold. That memory is why I started experimenting at home, determined to master a Buona Beef Tuna Genovese copycat recipe that could bring the same joy to my kitchen.
Why This Copycat Recipe Works
What makes this Buona Beef Tuna Genovese copycat recipe shine is the slow-cooked onion sauce inspired by Neapolitan cooking. Pairing tuna with deeply caramelized onions creates a rustic yet refined flavor profile that’s just as satisfying as the original. With pantry staples, a little patience, and some kitchen love, you can recreate this Chicago favorite anytime. If you enjoy Italian-inspired meals like this, you’ll also appreciate my take on San Giorgio Lasagna or a quick pasta night with Blackstone Tortellini, both of which share that same heartwarming Italian comfort.
Ingredients and Preparation

Serving Ideas and Tips
How to Serve It Best

The Buona Beef Tuna Genovese copycat recipe tastes incredible straight from the pan onto a toasted Italian roll. For that authentic Buona-style feel, serve it warm with the bread slightly crisp on the outside but soft inside. Add a side of pickled vegetables or a light green salad to balance the richness of the onion sauce. Many fans love pairing this sandwich with a simple pasta dish—something like a plate of penne pomodoro works perfectly and keeps the Italian comfort theme alive.
Tips for Leftovers and Storage
If you happen to have leftovers, store the tuna and onion mixture separately from the bread. Keep the filling in an airtight container in the fridge for up to three days. When reheating, warm it slowly on the stove so the onions retain their sweetness without burning. For a fun twist, you can also use the filling as a topping over rice or pasta, much like how I repurpose ingredients in recipes such as marry me chickpeas. It’s a creative way to stretch flavors while keeping meals exciting.
