Ingredients for steak submarine
Crispy breaded steak meets creamy cheese swirls in this restaurant-style masterpiece.
| Ingredient | Amount | Notes |
|---|---|---|
| Top Sirloin Steak 🥩 | 1 ½ lb | Thinly sliced against grain |
| All-Purpose Flour 🌾 | 1 ½ cups | For breading, sifted |
| Large Eggs 🥚 | 2 whole | Beaten for dredge |
| Panko Breadcrumbs 🍞 | 1 cup | Light and crispy |
| Provolone Cheese 🧀 | 8 oz | Sliced thinly for swirls |
| Hoagie Rolls 🥖 | 4 whole | Soft, slightly toasted |
| Yellow Mustard 🟡 | ¼ cup | For tangy base |
| Mayonnaise 🥛 | ¼ cup | Creamy texture |
| Fresh Lettuce 🥬 | 2 cups | Butter lettuce preferred |
| Tomato Slices 🍅 | 4 whole | Thinly sliced |
| Red Onion 🧅 | ½ whole | Thinly sliced |
| Olive Oil 🫒 | ½ cup | For frying steak |
| Salt 🧂 | 1 ½ tsp | Kosher preferred |
| Black Pepper 🌶️ | 1 tsp | Freshly ground |
| Garlic Powder 🧄 | 1 tsp | For seasoning |
The sirloin steak is your secret weapon—thinly sliced against the grain for maximum tenderness. Ask the butcher to slice it if your store doesn’t do it pre-cut. For the breading, I swear by Panko mixed with a little flour—it gives that perfect crunch without weighing down the steak. Grab hoagie rolls from the bakery section (not the pre-packaged ones), and toast them lightly before assembling. The provolone? Mild and melty is key—avoid the super-sharp kind unless you love bite with every bite.
No Panko? Regular breadcrumbs toasted in a dry pan for 2 minutes work in a pinch. Short on time? Pre-shredded provolone is fine, but grate your own for that perfect melt. The mustard-mayo mix can be prepped ahead—just keep it covered in the fridge. For the veggies, butter lettuce stays crisp longer than iceberg, and tomatoes with seeds removed prevent soggy bites. Want extra crunch? Add a handful of pickle chips or crispy fried onions on top.
This sandwich is best eaten fresh, but the breaded steak keeps 2 days in the fridge (reheat in a skillet for 1 minute). The cheese swirls? Make them just before serving—they lose their magic if prepped too early. For a crowd, double the steak and cheese, but keep the rolls separate until serving. Pro tip: Warm the rolls in the oven for 3 minutes before assembling—game changer for texture.

Step-by-step instructions for steak submarine with crispy breaded steak
Here's how to create a steak submarine that delivers crispy breaded steak and creamy cheese swirls in every bite.
👨🍳 Step 1: Prepare the Steak for Breading
Start by slicing the 1.5 lb top sirloin steak thinly against the grain into ¼-inch thick strips. This ensures tender bites that won't be chewy. Place the sliced steak in a shallow dish and season both sides generously with 1.5 tsp salt, 1 tsp black pepper, and 1 tsp garlic powder. Make sure each piece is well coated—this seasoning will carry through the breading process.
Let the seasoned steak sit for 10 minutes at room temperature. This brief resting period helps the seasoning adhere better and ensures even cooking. While it rests, create your breading station: place 1.5 cups all-purpose flour in one shallow dish, beat the 2 whole large eggs with a fork in another, and transfer the 1 cup panko breadcrumbs to a third dish. You'll work quickly through these three stations to get the perfect crispy coating.
🍳 Step 2: Bread the Steak for Maximum Crispiness
Heat 0.5 cup olive oil in a large skillet over medium-high heat until it shimmers but doesn't smoke. While the oil heats, dredge each steak strip first in the all-purpose flour, shaking off any excess. Then dip into the beaten eggs, letting any excess drip off, and finally coat thoroughly in the panko breadcrumbs, pressing gently to help the crumbs adhere. Work in batches to avoid overcrowding the skillet.
Once the oil is hot, carefully add the breaded steak strips in a single layer. Cook for 2-3 minutes per side until they're golden brown and crispy. The panko should puff up slightly and become deep golden, not pale. If you notice the breading browning too quickly, reduce the heat slightly to medium to prevent burning. Transfer the cooked steak to a paper towel-lined plate to drain excess oil while you prepare the rest.
🥘 Step 3: Assemble the Creamy Cheese Spread
In a small bowl, combine the 0.25 cup yellow mustard and 0.25 cup mayonnaise until smooth. Then add the 8 oz thinly sliced provolone cheese, mixing gently until just combined. The cheese should begin to soften and create a creamy swirl effect when spread. If the mixture seems too thick, add 1 teaspoon of warm water to help it spread more easily through the rolls.
Slice the 4 whole hoagie rolls in half horizontally and lightly toast them in a toaster or skillet until they're just warm and slightly crisp. This helps them hold up better to the filling. Spread the creamy cheese mixture evenly over the bottom half of each roll, leaving a ¼-inch border at the edges to prevent overflow when you add the other ingredients.
🍽️ Step 4: Build the Submarine Layers
Layer the steak submarine starting with the bottom half of each roll. Add ½ cup fresh lettuce (about ½ cup total per sandwich), followed by 1 whole tomato slice and ¼ of the sliced red onion (about ⅛ whole onion per sandwich). Then, arrange ¼ of the crispy breaded steak strips evenly over the vegetables. The steak should be spread out so each bite contains both steak and veggies.
Top each sandwich with the remaining roll halves, pressing down gently to help everything hold together. For an extra touch, you can lightly toast the tops in a skillet for 30 seconds per side until golden brown. This gives the submarine a restaurant-quality finish. Serve immediately while the bread is still warm and the cheese is creamy.
Pro Tips For Making Steak Submarine
- Pound Steak Thin: I learned this the hard way—top sirloin stays tough when it’s thick. Aim for ¼-inch thickness after pounding, or you’ll end up with chewy bites instead of that perfect melt-in-your-mouth texture. Use a meat mallet (or a heavy pan) and hit it evenly—no need to go crazy, just firm enough to flatten.
- Dry the Steak First: Skip the pat dry step, and your breading will clump like sad, soggy glue. Pat the steak thoroughly with paper towels before dredging—even if it feels like overkill. Wet spots mean uneven browning, and nobody wants a half-cooked crust.
- Rest Before Breading: Let the steak sit uncovered on a wire rack for 15–20 minutes after pounding. This evens out the surface tension so the flour sticks like it’s supposed to. I used to rush this, and my breading would slide off in chunks—now it stays put every time.
- Use Cold Provolone: Take the cheese straight from the fridge and slice it thin—about ⅛-inch thick. Cold cheese melts slower and doesn’t turn greasy when it hits the hot steak. If you’re lazy and use room-temp slices, they’ll pool like sad, stringy rivers instead of a smooth blanket. (Yes, I’ve done it.)
Serving suggestions for this steak submarine
Plating Presentation
For a restaurant-worthy look, arrange your steak submarine on a wooden cutting board or slate tray—this adds rustic charm while keeping everything contained. Use a sharp serrated knife to slice the hoagie roll diagonally at a 45-degree angle before serving.
This creates an elegant, open-mouthed presentation that reveals the crispy steak and creamy cheese swirls. 💫
Sauce Swirl Technique
The cheese swirls are your secret weapon for visual appeal. Use a small offset spatula or butter knife to spread the provolone-mayo mixture in a spiral pattern across the roll before adding toppings.
When you press the top half on, the cheese will create beautiful, golden swirls that peek out between the bread layers. For extra flair, drizzle garlic aioli or spicy mayo in a zigzag pattern on top.
Side Pairings
Serve with crispy shoestring fries tossed in smoked paprika and a squeeze of lemon for a classic diner vibe. For a lighter option, pair with a mixed greens salad featuring arugula, cherry tomatoes, and shaved parmesan—the peppery greens cut through the richness beautifully.
I also love adding pickle spears on the side to balance the meal with tangy acidity.
Garnish Like a Pro
Finish with freshly cracked black pepper and a sprinkle of smoked paprika for color and aroma. Add thinly sliced jalapeños for heat lovers, or microgreens for a delicate, fresh touch. A few crispy fried shallots on top add a luxurious crunch that elevates the dish instantly.
The key is to keep garnishes minimal—let the steak and cheese shine as the stars of the show.
Serving Style Options
For a casual lunch, serve the submarine wrapped in parchment paper with a toothpick flag for easy handling. For a dinner party, present it on a slate board with a small side of truffle aioli and warm dinner rolls.
If feeding a crowd, assemble the sandwiches in individual foil trays and keep them warm in a 200°F oven until serving to maintain crispiness.
Cheese Melting Hack
To ensure perfect cheese swirls, microwave the provolone slices for 10 seconds before mixing with mayo. This softens them slightly, making them easier to spread and creating those signature gooey pulls.
For an extra-melty effect, wrap the assembled sandwich in aluminum foil and warm in a 350°F oven for 2 minutes before serving. The residual heat will make the cheese even more decadent. 🔥

Frequently asked questions
Can I use a different cut of steak for this recipe?
While top sirloin works perfectly, flank steak or ribeye also deliver great results. Thinly slice against the grain for tenderness—flank steak is especially lean, so it crisps beautifully. Avoid tougher cuts like chuck or round, as they won't stay tender after breading. For extra juiciness, marinate the steak for 30 minutes in olive oil, garlic, and Worcestershire sauce before breading.
How do I keep the breaded steak from getting soggy?
Soggy breading is the enemy! Cook the steak in batches and keep it warm in a 200°F oven on a wire rack while assembling sandwiches. Avoid adding wet toppings (like raw tomatoes) until the very end—pat lettuce dry and use a paper towel to absorb excess moisture. For extra insurance, toast the rolls for 1-2 minutes before adding fillings to create a moisture barrier.
What's the best way to make the cheese swirls look professional?
Use a small offset spatula to spread the cheese-mayo mix in a tight spiral starting from the center of the roll. Press the top half on immediately after spreading—this traps the cheese between layers, creating those signature swirls when you slice. For extra drama, microwave the provolone slices for 10 seconds first to soften them slightly before mixing with mayo.
Can I make this recipe ahead of time?
Yes, but with strategy! Bread the steak and store it in an airtight container for up to 2 days, reheating in a skillet for 1 minute before using. Keep the cheese spread separate until serving—it's best fresh. Assemble the sandwiches just before eating, or warm them wrapped in foil at 350°F for 2 minutes to maintain crispiness. The rolls should always be toasted fresh for maximum texture.
What if I don't have hoagie rolls?
No problem! Use a brioche bun for extra richness or a ciabatta roll for more texture. For a lighter option, split a French baguette and lightly toast the halves. Avoid soft white bread—it won't hold up to the juicy filling. If using a baguette, slice it diagonally for that classic submarine look. Toast all breads until just warm to prevent sogginess.
