What Is Buona Beef Tuna Genovese?

The Buona Beef Tuna Genovese is a Chicago-style twist on a classic Italian sauce called Genovese, made with slow-cooked onions and tender meat. Traditionally, Genovese sauce is rich, sweet, and savory—built on caramelized onions and olive oil.
In this copycat version, we pair oil-packed Italian tuna with seasoned onions and a touch of beef broth for that authentic Buona flavor—without the hours of simmering.

Ingredients You’ll Need

Here’s everything you need for this flavorful Italian-style sandwich:

Step-by-Step: How to Make Buona Beef Tuna Genovese

1. Caramelize the Onions for Deep Italian Flavor

In a large skillet, warm olive oil over low heat. Add the sliced onions and cook slowly, stirring occasionally, for 25–30 minutes until golden brown and soft. Patience here makes all the difference—the deeper the color, the richer the flavor.

2. Add Aromatics and Build the Base

Stir in minced garlic, tomato paste, and anchovy paste if using. Cook for 2–3 minutes, letting everything become fragrant and slightly darkened. This forms the bold, savory base of your sauce.

3. Season and Simmer

Sprinkle in oregano and crushed red pepper flakes, then pour in the beef broth. Stir well and let it simmer for 5 minutes until it thickens slightly into a rich onion sauce.

4. Add the Tuna

Fold in the Italian tuna—use the oil from the can for extra flavor. Mix gently to keep the tuna in chunks instead of shredding it completely. Heat through for about 2–3 minutes until warmed.

5. Assemble & Toast the Sandwich

Spoon the hot mixture onto toasted ciabatta rolls or hoagie buns. Add provolone cheese if desired, then toast or press until the sandwich is warm and slightly melty.

6. Serve and Enjoy

Cut each sandwich in half, grab napkins, and dig in! It’s juicy, messy, and absolutely delicious—just like the original Buona Beef version.

Pro Tips for the Perfect Copycat Flavor

• Slow-Cook Your Onions: Don’t rush this step—it’s where most of the flavor develops.
• Use Quality Tuna: Oil-packed Italian tuna gives a smooth, rich texture and deep flavor.
• Adjust the Heat: Add more or less crushed red pepper flakes to suit your spice level.
• Cheese Upgrade: Provolone melts beautifully and pairs perfectly with the caramelized onion base.

Serving & Presentation Ideas

• Classic Lunch: Serve with a side of fries or a light salad.
• Party Option: Slice into smaller pieces and serve as sliders for gatherings.
• Meal Prep Idea: Make the onion-tuna mix ahead and assemble fresh sandwiches when ready to serve.

Storage & Reheating Guide

• Refrigerate: Store leftover tuna mixture in an airtight container for up to 3 days.
• Freeze: You can freeze it for up to a month—just thaw overnight before reheating.
• Reheat: Warm gently in a skillet over low heat, adding a splash of broth or olive oil if needed.

Recipe Variations & Substitutions

• Protein Swap: Try canned chicken or shredded turkey for a lighter version.
• Spicy Kick: Add extra crushed red pepper or a pinch of paprika.
• Gluten-Free Option: Serve on gluten-free buns or over rice for a low-carb twist.
• Dairy-Free Version: Skip the provolone or use your favorite vegan cheese alternative.
