Ingredients You’ll Need

Each ingredient in this Steak and Mushroom Grilled Cheese Sandwich Recipe plays an essential role in bringing texture and flavor to the sandwich. The choice of steak, mushroom, and cheese, paired with quality bread and butter, transforms it into a gourmet treat that’s simple yet unforgettable.

• 8 ounces flank steak, ribeye, or New York strip steak: Pick a cut that’s tender and flavorful to ensure a juicy, satisfying bite.
• Salt, to taste: Enhances all the natural flavors, especially the steak and mushrooms.
• Black pepper, to taste: Adds a subtle kick and depth to the seasoning.
• Olive oil, as needed: For cooking the steak and sautéing mushrooms, contributing a mild fruity note and helping with browning.
• 3 ½ ounces shiitake mushrooms, sliced very thinly: Their meaty texture and rich umami flavor complement the steak perfectly.
• 1 clove garlic, pressed through a garlic press: Adds a fragrant aroma and enhances the savory mushrooms.
• 4 slices good quality sourdough bread: The sturdy crust and tangy crumb offer the perfect base for grilling to golden perfection.
• 3 tablespoons unsalted butter, softened, for bread: Creates a crispy, buttery exterior with a lovely richness.
• 1 cup shredded Gruyere cheese (or other favorite cheese): Melts beautifully to bind everything with its nutty, creamy goodness.

How to Make Steak and Mushroom Grilled Cheese Sandwich Recipe

Step 1: Prep Ingredients

Start by gathering all your ingredients in one spot. Slice those shiitake mushrooms as thinly as possible; this helps them cook evenly and develop a beautiful caramelized flavor. Make sure the steak is ready for seasoning, and have your bread, butter, and cheese at hand to assemble without delay.

Step 2: Season and Cook Steak

Generously season your steak with salt and black pepper to bring out its natural flavors. Heat a grill pan or skillet over high heat until it’s very hot, then drizzle in olive oil to prevent sticking. Cook the steak for about 4 minutes on each side for a perfect medium-rare, or adjust the time to your preference. This step is where the steak gets that delicious crust and juicy interior that will make your sandwich unforgettable.

Step 3: Rest and Slice Steak

Once cooked, transfer the steak to a cutting board and let it rest for 10 minutes. Resting is crucial to keep the juices locked inside. Afterward, slice the steak thinly against the grain for maximum tenderness. Thin slices will spread beautifully throughout your sandwich and make each bite deliciously smooth.

Step 4: Sauté Mushrooms

While the steak rests, heat a large non-stick skillet over medium-high heat and drizzle with olive oil. Toss in your thinly sliced shiitake mushrooms and cook until they turn golden brown and develop a rich, savory flavor. Season with salt and pepper for balance, then add the pressed garlic, stirring until it’s fragrant, which should only take seconds. Setting these mushrooms aside afterward ensures they’re ready to add that fantastic umami punch to your sandwich.

Step 5: Assemble Sandwiches

Butter one side of each bread slice generously to ensure a crispy, golden crust later. On the unbuttered side, start layering: sprinkle about ¼ cup of shredded Gruyere cheese first, then add some of the thinly sliced steak, a hearty spoonful of the sautéed mushrooms, and finish with another ¼ cup of cheese. Top each sandwich with another bread slice, making sure the buttered side is facing out. This careful layering is the secret to a gooey, melty inside with a perfect crunch outside.

Step 6: Warm Oven

Preheat your oven to its warm setting, around 200 degrees Fahrenheit. This will come in handy if you’re making sandwiches in batches and want to keep them warm without drying them out before serving.

Step 7: Grill Sandwiches

Heat a clean skillet over medium-high heat and carefully place your sandwich buttered side down. Press gently with a spatula and cook for about 4 minutes, or until that side turns a beautiful golden-brown crisp. Flip the sandwich and repeat to achieve the same perfect color and crispy texture on the other side. The cheese will melt gorgeously during this step, creating that irresistible gooey center.

Step 8: Hold in Oven (Optional)

If your sandwiches are ready but you want to keep them warm for a bit, transfer them to the preheated oven. This step helps maintain the melty texture and prevents the bread from getting soggy while you finish grilling other batches.

Step 9: Serve

Slice the sandwiches however you like—halves or quarters work well for sharing. Serve immediately to enjoy the satisfying contrast between the crunchy bread, savory steak, tender mushrooms, and gooey cheese inside. This sandwich is best enjoyed fresh off the pan!

Garnishes

Adding simple garnishes can elevate the presentation and flavor of your Steak and Mushroom Grilled Cheese Sandwich Recipe. Fresh herbs like a sprinkle of chopped parsley or thyme brighten the sandwich’s richness with a pop of green and freshness. A few thinly sliced pickles on the side provide a tangy crunch that contrasts beautifully with the creamy cheese and savory steak.

Side Dishes

This sandwich pairs wonderfully with classic sides that complement its hearty, rich profile. Think crispy potato chips for a salty crunch or a light mixed green salad dressed in a zesty vinaigrette to cut through the butteriness. For something more indulgent, creamy tomato soup serves as a delicious dip, making every bite even more comforting.

Creative Ways to Present

For a fun twist on serving your Steak and Mushroom Grilled Cheese Sandwich Recipe, consider cutting the sandwich into bite-sized sliders for a party platter. You can also serve it open-faced with a sprinkle of microgreens on top for a gourmet touch. Styling the plate with a drizzle of balsamic glaze or a smear of horseradish mayo elevates the look and adds extra flavor dimensions.

Make Ahead and Storage

Storing Leftovers

If you have leftovers (which might not happen with this recipe!), wrap them tightly in parchment paper or plastic wrap and store them in an airtight container in the refrigerator. This keeps the sandwich from getting soggy and the flavors fresh for up to 24 hours.

Freezing

While grilled cheese sandwiches are best enjoyed fresh, you can freeze them if necessary. Wrap each sandwich tightly in foil or plastic wrap and place in a freezer-safe bag. They’ll keep well for up to 1 month. Just be aware that the texture of the bread may change slightly upon thawing.

Reheating

To bring back that crispy exterior and gooey center, reheat your sandwich in a skillet over medium heat rather than using the microwave. This method ensures the bread gets crispy again and the cheese melts evenly. For convenience, you can also warm it in the oven at 350 degrees Fahrenheit for about 10 minutes.

FAQs

Can I use a different type of cheese for this Steak and Mushroom Grilled Cheese Sandwich Recipe?

Absolutely! While Gruyere is recommended for its meltability and nutty flavor, you can substitute with sharp cheddar, fontina, or even mozzarella depending on your taste preference.

What is the best steak cut for this sandwich?

Flank steak, ribeye, or New York strip are all excellent choices because they balance tenderness and flavor perfectly, making the sandwich extra satisfying.
