You’ll need:

  • 1 teaspoon of kosher salt (divided in half)
  • 1 teaspoon of fresh cracked black pepper (divided in half)
  • 2 ounces of patio or flank steak
  • 1½ tablespoons of extra virgin olive oil
  • 1 tablespoon of salted sweet cream butter
  • 1¼ cup of thinly sliced sweet yellow onion
  • 2 tablespoons of salted sweet cream butter, softened
  • 8 slices of bread (your favorite type – I used Italian bread)
  • 2¾ cups of freshly grated mozzarella cheese

Substitutions And Additions

STEAK: This sandwich can be made using leftover steak. Thinly slice the cold steak. Cook the onions as you would for the recipe, and add steak in to warm it up.

TOPPINGS: You can add thinly sliced fresh mushrooms or green peppers while you are cooking the onions for an added twist.

SAUCE: You can spread a thin layer of horseradish sauce or stone ground mustard to the unbuttered side of the bread for a spicy kick.

BREAD: The sky’s the limit for which bread to choose. Italian bread, white bread, or whole wheat bread all work. Or pick something gourmet such as focaccia bread. Try to pick a sturdy bread so that none of the cheesy goodness leaks out.

CHEESE: Try Monterey Jack, Pepper Jack cheese, American cheese, or provolone cheese – any cheese you like on your grilled sandwiches would be a great substitute.

SPICE: If you don’t want to just stick to salt and pepper to season your steak, try sprinkling Montreal steak spice or another similar seasoning.

How To Make This Steak Grilled Cheese Recipe

OUR RECIPE DEVELOPER SAYS

The best way to get your cheese to melt is if you let it sit out at room temperature for 15 to 20 minutes before you start making these.

STEP ONE: Evenly sprinkle ½ teaspoon kosher salt and ½ teaspoon fresh cracked black pepper on both sides of the steak. Set it aside.

STEP TWO: Using a 10 to 12-inch non-stick skillet over medium-high heat, heat oil and the tablespoon of butter. 

PRO TIP:

This would also be fantastic grilled in a panini press instead of on the stovetop.

STEP THREE: Add the thinly sliced onion to the melted butter. 

STEP FOUR: Sprinkle the onions with the remaining ½ teaspoon of kosher salt and cracked black pepper.

Cook for 5 to 7 minutes, stirring frequently, or until golden. Remove the onions from the skillet, and set them aside.

STEP FIVE: Keep the skillet over medium-high heat, and add the seasoned steak. Cook for 3 to 4 minutes per side.

Remove the steak from the skillet and allow it to rest for 5 minutes. Remove the skillet from the heat and wipe out the skillet.

STEP SIX: Once the steak has rested, thinly slice it. Evenly divide the sliced steak into 4.

STEP ELEVEN: Once all 4 sandwiches are assembled, heat the skillet to medium-high heat. 

PRO TIP:

Keep a close eye on the temperature, and adjust up or down to avoid burning the sandwich.

STEP TWELVE: Once the bottom of the sandwich is golden brown, carefully flip the sandwich over.

Remove the sandwich from the skillet, slice it with a sharp knife, and serve immediately.

How To Serve

The best way to serve grilled cheese is with a bowl of tomato soup on the side and a glass of cold milk to wash it down. This sandwich would be a great option for a quick lunch or light dinner.

Storage

IN THE FRIDGE: Store any leftovers in an airtight container up to overnight. Reheat in the skillet.

IN THE FREEZER: We don’t recommend freezing this sandwich. It is best made fresh.

Grilled cheese is a classic sandwich, but it doesn’t mean you have to stick to just slices of cheese and bread. The best part about these sandwiches is that you can make them your own with plenty of toppings. Our steak and onion grilled cheese sandwich does just that, and you will love the endless possibilities.

Frequently Asked Questions

Can I keep the leftovers of this sandwich until the next day?

You can keep leftover sandwiches in the fridge until the next day. Reheat in a skillet to melt the cheese again.

What other toppings could I add to my sandwich?

In addition to onions, add thinly sliced mushrooms or bell peppers to your sandwich.

What is the best bread to use for this steak sandwich?

Any bread will work for this cheesesteak grilled cheese sandwich. Try French bread, Italian bread, ciabatta, rye bread, or even sandwich bread.
