Ingredients You’ll Need
Here’s where the magic begins: each ingredient in this Steak Sandwich Recipe plays a crucial role in building layers of flavor, color, and texture. They’re all easy to find, but together, they’re simply unbeatable.
- Unsalted Butter (1/2 cup): The base for our herb butter, giving richness and creaminess to the sandwich.
- Fresh Dill (1 tbsp, diced): Adds a subtle herbal brightness that lifts the overall flavor.
- Garlic Cloves (3, crushed): Garlic’s pungent aroma and taste perfectly complement the butter and steak.
- Oil (1 tbsp): For searing the steak and sautéing the onions to golden perfection.
- Steak (1 lb): Thinly sliced and seasoned, it’s the hearty, protein-packed star of this dish.

How to Make Steak Sandwich Recipe
Step 1: Prepare the Herb Butter
Start with mixing the softened unsalted butter, crushed garlic cloves, and diced fresh dill in a bowl until well combined. The herb butter spreads a vibrant garlicky, herby richness across your bread and makes every bite decadently flavorful. Set this aside—you’ll use it shortly.
Step 2: Slice the Steak
Slice your steak into thin strips for quick, even cooking. A neat little trick to make slicing easier is to freeze the steak for about 15-20 minutes beforehand. This firms up the meat so you get precise, clean cuts that cook thoroughly and quickly without losing juiciness.
Step 3: Cook the Steak
Heat the oil in a skillet over high heat. Add the sliced beef, season generously with salt, and cook just until golden on the outside but still tender inside. Overcooking will dry it out, so keep a close eye. Once done, remove the steak from the skillet and set aside for the next step.
Step 4: Sauté the Onions
Using the same skillet to keep those wonderful beef flavors, throw in the sliced onions. Sauté them until they turn golden brown and soft—it’s this caramelized sweetness that adds depth and a slight crunch to your sandwich. Remove from the heat once they’re perfectly browned.
Step 5: Assemble and Broil
Slice your baguette lengthwise and spread the prepared herb butter evenly on both sides. Layer the steak strips first, then top with the sautéed onions, and finally add slices of Havarti cheese. Keep the sandwich open-faced and pop it under the broiler for about 2 minutes or until the cheese melts and bubbles beautifully. Keep an eye on it to avoid burning!
How to Serve Steak Sandwich Recipe

Garnishes
Fresh herbs like a few sprigs of dill or parsley sprinkled on top add a fresh pop of color and brightness. You can also add thin slices of pickles or a drizzle of a tangy mustard sauce if you want a little zing. These simple extras elevate the sandwich’s flavors and make it look irresistible.
Side Dishes
This steak sandwich pairs wonderfully with crispy french fries, a simple green salad, or even a bowl of hearty tomato soup. The contrast of textures and complementary flavors make for a balanced meal that’s bound to satisfy beyond all expectations.
Creative Ways to Present
Try cutting the sandwich into smaller portions to create sliders for a party or family gathering. You could also serve it open-faced on rustic wooden boards, garnished with microgreens for restaurant-quality presentation at home. The versatility of this Steak Sandwich Recipe means you can adapt it to any occasion with a touch of creativity.
Make Ahead and Storage
Storing Leftovers
Wrap any leftover sandwich tightly in plastic wrap or aluminum foil to keep it fresh. Store it in the refrigerator and enjoy within 2 days for the best taste and texture. Keep components like the herb butter separate if you want the bread to remain crisp.
Freezing
You can freeze the cooked steak strips separately in an airtight container for up to 3 months. The baguette and cheese don’t freeze well, so assemble fresh after thawing. This way, you can quickly recreate your Steak Sandwich Recipe anytime with minimal effort.
Reheating
Reheat leftover steak strips gently in a skillet over medium heat to avoid drying them out. If the sandwich is assembled, warm it in an oven at 350°F (175°C) wrapped loosely in foil for about 10 minutes or until heated through and the cheese melts again.
FAQs
What cut of steak is best for this sandwich?
Flank steak or skirt steak works wonderfully due to their rich flavor and ability to be sliced thinly. They cook quickly and stay tender, making them perfect for this Steak Sandwich Recipe.
Can I use a different cheese?
Absolutely! While Havarti melts beautifully and adds creaminess, you can substitute provolone, Swiss, or even mozzarella based on your preference for a slightly different but equally delicious taste.
Is it possible to make this vegetarian?
While this Steak Sandwich Recipe focuses on meat, you can swap the steak with grilled portobello mushrooms or marinated tempeh slices for a satisfying vegetarian alternative.
How spicy is this sandwich?
It’s not spicy by default but full of bold flavor from the garlic and herbs. If you like a little kick, add a dash of hot sauce or a sprinkle of crushed red pepper flakes when assembling.
Can I prepare this sandwich ahead of time?
You can prepare the herb butter and slice the steak ahead to save time on the day you want to serve it. However, it’s best to assemble and broil the sandwich just before eating to enjoy the cheese melted perfectly and the bread crisp.
