    There is nothing like a good sandwich recipe.  They are incredibly simple to make and have the ability to mix and match different toppings and cheeses to adapt to your taste buds.  A good steak sandwich obviously starts with 8-10-ounce ribeyes.

    The beef is seasoned and seared to a perfect medium-rare, but of course, you can cook it longer should you desire a more cooked through internal temperature. It’s then placed in a toasted bun with peppers, onions, mushrooms, cheese, and sauce.  This my friends is one tasty sandwich.

    Whether you are making a  The Ultimate Chicken Club Sandwich and Chicken Melt Recipe, a Kentucky Hot Brown Sandwich Recipe, or a croque monsieur, there is an art to making the perfect sammie.

    Steak Sandwich Toppings

    There is an assortment of toppings that you can add to a ribeye steak sandwich, but I prefer roasted bell peppers, and that can be red, green, yellow, or orange.  In addition, caramelized yellow onions and some wonderful flavors along with some roasted mushrooms.  You can use mushrooms such as buttons, cremini, or portabella mushrooms.  The trick to these toppings being delicious is to ensure they are properly roasted and caramelized.

    Best Steak To Use

    • Ribeye – full-flavored, tender, but can be fatty
    • New York Strip  – lean, flavorful, can be tough depending on the grade of beef
    • Flank– Lean, tough, needs to be cooked to at most medium rare
    • Skirt – lean, tough, can be fatty, and needs to be cooked to at most medium-rare.

    How to Make It

    I had a few leftover ribeyes which is really the reason for this recipe.  The ribeye steaks I had were pretty thick, so I placed them in the freezer for 30 minutes until they were just a tad bit firm.  Next, I thinly sliced them, into 3 individual slices.

    When you freeze them they are easier to cut, plus a thinner cut of ribeye makes for an easier-to-eat sandwich.  See what I did there!  Once they are sliced, season them well and set them aside.

    How to Cook It

    I prefer to use a preheated grill pan to cook the steaks or over an open-flame grill.  Not only do you get those coveted grill marks but the flavor seems to be intensified when doing it this way.  Since ribeyes can be on the fatty side, grilling them will render some of the fat as it drips down through the grill grates making it slightly leaner.

    I grilled the steaks for 3 to 4 minutes per side over medium-high heat to achieve a medium-rare internal temperature.  If you liked a more medium-done steak, then cook it for an extra 90 seconds per side to achieve a medium to medium-well internal temperature.  It is also incredibly important to rest your steaks on your cutting board for 2 to 3 minutes before serving it into the sandwich.

    Ribeye Steak Sandwich Cooking Methods

    • Pan-Roasted – oil heated in a pan until lightly smoking and cook over medium-high heat on both sides.
    • Broiled – setting the oven to broil on high heat and cook it for 5 to 6 minutes per side.
    • Grilling – cooked in a grill pan or over the open flame over medium-high to high heat on both sides.

    How to Make a Garlic Aioli

    Garlic aiolis are super easy to make. Simply whisk together some finely minced garlic, mayonnaise, a bit of lemon juice, and salt and pepper.  Yup, it’s that easy but boy oh boy does it pack a punch in the flavor department.

    To take this garlic aioli one step further, I diced to mix in some whole grain mustard and some horseradish.  The combo of flavors in this garlic aioli sauce compliments the ribeye steak sandwich so well!

    3. Season the steak on both sides and grill on an open flame or in a grill pan on medium-high heat with olive oil until grill marks are formed and the desired internal temperature has been achieved.
    4. Add the steak to the hoagie bun and layer on cheeses, peppers, onions, and mushrooms.
