This mushroom swiss steak sandwich has quickly become one of my new favorite sandwiches to make. It has steak and a rich creamy mushroom sauce on top leaving your tastebuds nothing but satisfied!

A ribeye steak is by far one of my favorite things to cook over open fire. The ribeye is a really well marbled cut of beef and it has a ton of flavor in it. You can use whichever cut of steak you prefer for this cook – the trick is making sure that you slice it thin enough for a nice tender bite.

Ingredients you will need

Protein: Ribeye steak – you can use any cut you want, but I used a BetterFed Beef ribeye because it’s super tender and has a lot of flavor.

Sauce: Mushrooms, onions, Worcestershire sauce, red wine and heavy whipping cream, flour

Seasonings: SPG Blend, fresh thyme

Sandwich: Ciabatta Bun, swiss cheese

How to make a Mushroom Swiss Steak Sandwich

Start, by seasoning your ribeye with your favorite steak rub – I used SPG (salt, pepper, garlic powder blend). Let the ribeye sit at room temp for 30-60 minutes. This is not required, but it helps the steak cook quicker and it tends to result in a more tender bite into the steak.

Insert a Meatermade MEATER Plus probe to help you monitor your internal temperature while you grill the steak. You can cook the steak to your desired doneness, but for this cook I am targeting a tender, juicy medium rare which means I am going to remove it from the heat once the steak reaches an internal temp of 124°F. With a 10 minute rest, the internal temp will reach between 133° – 135°F.

Grill the steak over direct heat flipping it every 3-4 minutes. Once it reaches an internal temp of 124°F, remove it from the Nomad Grills and let it rest for 10 minutes.

While the steak is resting, add butter to a skillet with the mushrooms and onions and let it cook for 5 minutes over high heat. Once they begin to soften, add the fresh thyme, flour, salt and pepper and stir. Let it cook for 2 minutes, then add the Worcestershire, red wine and heavy whipping cream then let it cook until thickened.

Assemble the sandwich on a toasted ciabatta bun. Add a thin layer of mushroom cream sauce to the bottom bun, add a layer of thinly sliced steak, a slice of swiss cheese and top it with more mushroom cream sauce.
