When it comes down to delivering the Best Steak Sandwich recipe, everyone has a strong opinion about theirs. Guess what? We are no different! This is our approach to a beautiful Steak Sandwich recipe which has been perfected over years and years of trial and error

Now for the fun part. We actually don’t agree on what the best Steak Sandwich recipe actually it! That’s right, we’ve got completely different recipes here for you to choose from. I prefer the classic combination of Steak and Eggs in my Sandwich. On the flip side, she prefers Steak and Brie. Honestly, both are extremely tasty, so we’ve decided that in this recipe we’ll share both. The good news is, you can make both and try for yourself. Let us know which one you prefer in the comments, or hit us up on our Instagram!

The baseline ingredients for The Best Steak Sandwich Recipe remain the same, and this is the key to perfecting the Sandwich. Good quality steak, Caramelized Onions, and good quality bread. Both Sandwich recipes have these at the core. So provided you follow our approach for Steak, Onions and Bread, you can have fun with whatever other toppings you choose!

What Steak to use in the Best Steak Sandwich Recipe?

Any steak will do great in a Steak Sandwich and this choice does come down somewhat to personal preference. If you have leftover steak from dinner the night before then a Steak Sandwich is a perfect meal choice for Lunch the next day. So Roast Beef, Ribeye, Skirt, Flank, are all great choices. For this recipe however, and when making the sandwich from scratch we recommend using Sirloin. Sirloin is a hearty piece of meat with loads of flavor. It is quite cheap to buy when compared to other dishes and soaks up all the flavors in this recipe very well. So why not give Sirloin a try!

Caramelized Onions are key!

In our opinion good quality Caramelized Onions are non-negotiable when it comes to a Steak Sandwich. Steak and Onions are such a naturally great pairing, and this is true in the Sandwich. The natural sweetness of slow cooked, Caramelized Onions add so much depth of flavor to the dish. They also pair very well with sauces that deliver more acidity and sharpness, such as mustard. Red Onions are our preferred Onions of choice for Caramelization. They are naturally quite sweet and taste phenomenal

What Bread to use?

The best bread to use for The Best Steak Sandwich recipe is, in our opinion, Sourdough. Unlike some other popular bread choices such as Brioche, or Potato rolls, Sourdough is much more durable and supports the Steak much better. A Steak Sandwich naturally is a lot tougher than a standard Burger using ground beef, or even a Chicken Sandwich. The Steak is sturdy, so needs an equally sturdy bread to keep the structure in place. Slightly toast the Sourdough to get that beautiful crusty outside for the perfect bite every time

Steak and Egg Sandwich

My personal favorite is the classic Steak and Egg Sandwich. Perfectly fried Eggs cooked sunny side up laid on top of those delicious cuts of perfectly cooked beef. Press down on the sandwich and all of that beautiful, gooey Egg Yolk drizzles all over the sandwich. Who can resist a sandwich like that?!

For this sandwich, the only additions to the baseline of Caramelized Onions are American Cheese and Romaine Lettuce. The sauce is just a simple mixture of Japanese Kewpie Mayonnaise and Dijon Mustard. A perfect sandwich if we ever saw one!

Steak and Brie Sandwich

The addition of Brie to a Steak Sandwich completely changes the meal, in a good way. Brie Cheese is quite a powerful flavor, and when we’re talking about Steak Sandwiches there is no need to be subtle. Heavy layers of Brie Cheese compliment the delicious Steak and counteract exceptionally well with those sweet Caramelized Onions

Final additions to this beautiful sandwich are Romaine Lettuce, thick slices of fresh Tomato, and the same Mayonnaise and Dijon Mustard sauce as the Steak and Egg Sandwich
