There is nothing like a good sandwich recipe. They are incredibly simple to make and can mix and match different toppings and cheeses to adapt to your taste buds. If you’re a hot sandwich fan, try my Kentucky Hot Brown Sandwich Recipe or a croque monsieur.
Steak sandwich consists of hot or chilled cooked beef that is served inside a bun or hoagie with assorted toppings and a sauce. It can also feature greens such as lettuce or microgreens. A steak sandwich can be customized in any way to meet your taste buds’ desires. It is up to you, from the type of beef to the bread, toppings, or sauce. There are no boundaries.
The steak sandwich was invented at the Louis’ Lunch restaurant in Connecticut, where they served up a “hamburger sandwich.” It looks and eats like a patty melt with a burger served with cheese and toppings on plain white bread.
Ingredients and Substitutions
- Beef – You will need fresh or thawed frozen ribeye steak for my recipe.
- Fat – Olive oil or butter work great for cooking the beef.
- Vegetables – I use red and green bell peppers, but orange and yellow can also be used. In addition, you’ll need a white, sweet, or yellow onion.
- Mushrooms – Regular button mushrooms work well for this. Cremini mushrooms are also an option for this steak sandwich.
- Sauce – I use my famous garlic aioli sauce on the sandwich.
- Cheese – Mozzarella or provolone cheese work very well. I like to use a combination of to make this extra cheese.
- Bread – A good hoagie roll is what you’ll need.
How to Make a Steak Sandwich
- Roast the onions in a pan over medium-low heat in some butter until golden brown, which takes about 20 minutes. Set them aside.
- In the same pan, roast the peppers and mushrooms over medium-low heat in some butter until browned, which takes about 10 minutes.
- Season the steak on both sides with salt and pepper and grill at 450° to 550° 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.
- Add the steak to the hoagie bun and layer on cheese, peppers, onions, and mushrooms.
- Bake the sandwiches at 400° for 5 minutes or until the cheese is melted and the bun is lightly toasted.
- Serve with aioli.
What’s the 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, must be cooked to medium rare.
- Skirt – lean, tough, can be fatty, and must be cooked to medium-rare.
Steak Sandwich Cooking Methods
Pan-Roasted – oil heated in a pan until lightly smoking and cooked 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.
Make-Ahead and Storage
Make-Ahead: This steak sandwich is meant to be eaten as soon as it’s done cooking. If you keep the sauce, veggies, mushrooms, and beef separate, you can make this up to 2 days ahead of time.
How to Store: It is best to cover the sauce, cooked beef, bread,veggies, and mushrooms separate. If it is already assembled, cover the sandwich with plastic and keep it in the refrigerator for 3 days. This recipe will not freeze well.
How to Reheat: Place the desired number of sandwiches on a sheet tray lined with parchment paper and bake them in the oven at 350° for 8 to 10 minutes or until warm. If you kept the main components of the dish separate, follow the procedures of the recipe for reheating.
chef notes + tips
- The beef in my recipe 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.
