Why You’ll Love This Recipe

This is a pretty easy recipe to make, and is furthermore a great way to help picky steak lovers branch out! With only 15 minutes of prep and 25 minutes of cook time, you’ll be ready to serve 4. 

The steak can be of your choice between ribeyes, filets or sirloins, but I chose ribeye steak. 

Slicing the ribeyes for the mushroom Swiss steak sandwich.

The key is keeping a medium heat fire to the skillet while making the mushrooms. Cook the fresh mushrooms first to let them “sweat” out the water. Also make sure to add the cream at the end of the sauce making process so it doesn’t separate.

Steak and cheese sandwiches are best served with a side dish like mashed potatoes or grilled asparagus! The delicious sauce can also act as a wonderful mushroom gravy to bring your mashed potatoes to the next level. Who knows– this steak sandwich might become one of your favorite recipes to bring out when company comes over. Fire up your grill and let’s go!

Ingredients

To make these hearty sandwiches, you’ll start out by coating 2-3 ribeyes in kosher salt, black pepper, garlic powder, and canola oil as needed.

The bone marrow after being flipped on the grill.

For the bone marrow, you’ll need bone marrow canoes, a little bit of kosher salt, and a gallon of water. 

Then, you’ll create the mushroom cream sauce out of the cooked bone marrow, sliced mushrooms, beef broth, heavy cream, minced garlic, black pepper, and kosher salt.

Finish off the sandwich with a brioche bun and Swiss cheese.

How to Make Mushroom Swiss Steak Sandwiches

I Got a Bone to Pick with You

At least 24-48 hours before cooking, add 1 gallon of water and ¼ cup of salt to a bowl. Mix that together until the salt dissolves. Add your bone marrow to the mixture, cover and place in the fridge. 

Let sit in the fridge for at least 12 hours, but ideally 24-48 hours. Make sure to change out the water and remix the salt every 12 hours. Once done, pull out your bones and lay out on a tray. Season with salt and place in the fridge until ready to use.

I know this is some extra work, but I highly recommend going through the process! This bone marrow is the secret ingredient that really takes the mushroom cream sauce to the next level!
