What is Buona Beef Tuna Genovese? Understanding the Fusion
A Bold Italian-American Mash-Up
The Buona Beef Tuna Genovese stands as a testament to Italian-American culinary inventiveness. This remarkable dish reimagines the traditional southern Italian Genovese onion sauce from Naples, blending it with the hearty spirit of Chicago deli sandwiches. Buona Beef, already renowned for their Italian beef, created something entirely unique by combining tender roast beef with a rich, creamy tuna sauce that draws inspiration from both Ligurian and Neapolitan culinary traditions.
The Unexpected Pairing of Beef and Tuna
While the combination might sound unusual, it has deep roots in Italian cuisine. The pairing draws inspiration from the classic Vitello Tonnato – a traditional dish of chilled roast veal served with a creamy tuna sauce. Buona’s genius twist transforms this elegant, cool appetizer into a warm, hearty, handheld sandwich that satisfies on an entirely different level. The surf-and-turf concept becomes approachable comfort food that celebrates both land and sea flavors in perfect harmony.
The Culinary Journey: From Italy to Your Plate
Genovese Tuna: Ligurian Roots vs. Neapolitan Influence
Understanding this dish requires appreciating the complexity of Italian regional cuisine. “Genovese” can refer to two distinct preparations: the slow-cooked onion sauce from Naples that typically accompanies pasta, or the lighter, fish-based preparations from Liguria featuring tuna, anchovies, capers, and lemon. This copycat recipe masterfully draws from the Ligurian concept with its emphasis on quality tuna and briny Mediterranean flavors, while incorporating the rich, slow-cooked depth reminiscent of Neapolitan Genovese through caramelized onions and complex layering.

Buona Beef’s Iconic Contribution in Chicago
Buona Beef transformed this Italian inspiration into a Chicago institution, creating what many consider a hidden gem in their extensive menu. This Italian beef specialist took their expertise in crafting satisfying sandwiches and applied it to an entirely new flavor profile, establishing a culinary legacy that bridges traditional Italian techniques with American sandwich culture.
Inspiration Behind the Copycat
The beauty of recreating this dish at home lies in personalizing the flavor balance to your preferences. Drawing inspiration from culinary traditions while adapting techniques for the home kitchen, this recipe celebrates both heritage and innovation. The combination of premium ingredients and careful preparation transforms simple components into something extraordinary that honors both Italian culinary roots and American creativity.
Ingredients That Make the Flavor Shine
The Essential Tuna: Oil-Packed Italian Varieties
The foundation of exceptional Tuna Genovese begins with premium oil-packed tuna. Unlike water-packed varieties, oil-packed tuna provides the richness, texture, and authentic flavor essential for creating a truly satisfying sauce. The oil serves as both a flavor carrier and a crucial component in achieving the proper creamy consistency.
Top Italian Tuna Brands
Rio Mare offers consistent quality with a tender texture that flakes beautifully while maintaining structure. Callipo provides a more robust, meaty texture with exceptional flavor depth. Ortiz brings Spanish influence with their premium processing techniques, while As do Mar delivers authentic Mediterranean character with their traditional preparation methods. Each brand offers unique qualities that can subtly influence your final dish.
Crafting the Creamy Tuna Genovese Sauce
The sauce represents the heart of this dish, requiring careful balance of several key components. Anchovy fillets provide deep savory notes and umami complexity without overwhelming fishiness. Fresh garlic adds aromatic intensity, while capers contribute essential salty tang and textural interest. Fresh lemon juice brings crucial acidity that brightens the entire mixture, and quality extra virgin olive oil carries flavors while adding richness. Mayonnaise creates the creamy base that binds everything together into a luscious, spreadable consistency.
The Tender Roast Beef Component
Thin slices of quality roast beef provide the sandwich’s structure and heartiness. Whether using premium deli roast beef or preparing your own, the key lies in achieving tender slices that complement rather than compete with the delicate tuna sauce. The beef should be warmed gently to enhance its flavor without overcooking.
Choosing the Perfect Bread Base
The bread must be sturdy enough to support the generous sauce and fillings without becoming soggy. Ciabatta rolls offer an ideal combination of crusty exterior and airy interior, while Italian hoagie rolls provide traditional submarine sandwich structure. A crusty baguette, sliced lengthwise, creates an elegant presentation perfect for sharing.
Flavor Boosters & Optional Additions
Peppery arugula adds fresh contrast and slight bitterness that balances the rich sauce. Pickled red onions provide acidic crunch and vibrant color. Shaved parmesan contributes nutty complexity, while fresh parsley adds herbaceous brightness. Freshly cracked black pepper enhances all flavors, and a touch of hot sauce can add welcome heat for those who enjoy spicier preparations.
Step-by-Step Buona Beef Tuna Genovese Copycat Recipe
Prep Time: 15 minutes
Cook Time: 5 minutes
Total Time: 20 minutes
Yield: 4 generous sandwiches
Ingredients
For the Creamy Tuna Genovese Sauce:
- 2 cans (5 oz each) premium oil-packed Italian tuna, drained
- 4 anchovy fillets, finely minced
- 3 garlic cloves, minced
- 2 tablespoons capers, drained and chopped
- 3 tablespoons fresh lemon juice
- 1/4 cup extra virgin olive oil
- 1/3 cup high-quality mayonnaise
- 2 tablespoons fresh parsley, finely chopped
- Salt and freshly ground black pepper to taste
For the Sandwich:
- 1 pound thinly sliced roast beef
- 4 ciabatta rolls or Italian hoagie rolls
- 2 cups fresh arugula
- 1/2 red onion, thinly sliced and pickled (optional)
- 1/2 cup shaved Parmesan cheese
- Extra virgin olive oil for drizzling
Instructions
Creating the Creamy Tuna Genovese Sauce
In a medium bowl, use a fork to gently flake the tuna into smaller pieces while maintaining some texture. Add the minced anchovies and garlic, mixing gently to distribute evenly. Incorporate the chopped capers, then slowly drizzle in the lemon juice while stirring. Add the olive oil gradually, followed by the mayonnaise, stirring until you achieve a creamy, cohesive consistency. Fold in the fresh parsley and season generously with salt and pepper. Taste and adjust seasoning as needed. For enhanced flavor, refrigerate for 30 minutes to allow flavors to meld, or gently warm in a small saucepan over low heat for a more traditional warm sandwich experience.
Optional: Adding a Slow-Cooked Onion Base
For deeper flavor complexity, thinly slice 2 large yellow onions and cook them slowly in 3 tablespoons of olive oil over medium-low heat for 30-40 minutes, stirring occasionally until golden and jammy. Season with salt and pepper. This caramelized onion mixture can be layered with the tuna sauce for additional richness and authentic Genovese flavor depth.
Warming the Roast Beef
Heat the roast beef slices gently in a large skillet over medium-low heat for 2-3 minutes, or warm briefly in the microwave. The goal is to take the chill off without cooking the meat further.
Preparing the Bread
Slice the rolls horizontally and lightly toast the cut sides under the broiler for 1-2 minutes until golden. This creates texture contrast and helps prevent the bread from becoming soggy.
Assembling the Sandwich
Spread a generous layer of the tuna Genovese sauce on the bottom half of each roll. If using the caramelized onions, add a layer over the sauce. Arrange the warmed roast beef over the sauce, then top with fresh arugula, pickled red onions if desired, and shaved Parmesan. Drizzle lightly with extra virgin olive oil and finish with freshly cracked black pepper. Cap with the top half of the roll and let sit for 2-3 minutes to allow flavors to meld before serving.
Serving Tips, Storage & Creative Twists
Ways to Serve It Up
The Classic Sandwich
Enjoy this as a substantial lunch or perfect picnic fare. The sandwich travels well and actually improves as the flavors continue to meld during transport.
Beyond Bread: Plated Dinner Options
Transform this into an elegant dinner by serving the tuna mixture over warm pasta, creamy polenta, roasted fingerling potatoes, or a bed of mixed greens. For pasta lovers, consider serving over one pot creamy garlic pasta or healthy broccoli pasta. Garnish with fresh lemon zest, additional parsley, and a drizzle of premium olive oil for restaurant-quality presentation.
Appetizer Ideas
Create sophisticated crostini by spooning the tuna mixture onto toasted baguette slices, finishing with a light balsamic drizzle and microgreens for an impressive starter.
Storage & Leftovers
Store the tuna sauce and any caramelized onions separately in airtight containers in the refrigerator for up to 3 days. The flavors actually improve overnight, making this an excellent make-ahead option. Always assemble sandwiches fresh to prevent soggy bread, but the prepared components can be quickly assembled for weekday lunches.
Recipe Variations & Dietary Adaptations
Gluten-Free
Serve over toasted gluten-free bread, grilled polenta rounds, roasted sweet potato slices, or atop a bed of fresh greens for a satisfying salad that maintains all the dish’s essential flavors. Consider pairing with salmon sweet potato combinations for inspiration.
Dairy-Free
Replace mayonnaise with high-quality aquafaba mayo, cashew cream, or create a traditional olive oil and egg yolk emulsion for authentic richness without dairy.
Plant-Based
Substitute the tuna with seasoned mashed chickpeas or marinated artichoke hearts combined with seaweed flakes for oceanic flavor. For inspiration on plant-based protein options, try our chickpea tuna salad recipe. Replace the beef with thick slices of grilled eggplant or smoky marinated tofu for satisfying protein and texture.
Best Pairings
Sides
Complement this rich sandwich with bright, acidic sides like additional pickled vegetables, peppery arugula salad, roasted vegetables, or crispy potatoes. For lighter options, try pairing with a refreshing creamy cucumber salad or crispy baked parmesan zucchini. The goal is balance against the sandwich’s richness.
Wine Pairings
Italian whites such as Vermentino, Soave Classico, or Gavi provide crisp acidity that cuts through the richness while honoring the dish’s Italian heritage. For red wine lovers, a bold Spanish Rioja offers enough structure and complexity to stand up to the robust flavors.
