What Kind of Steak Should I Use?
For maximum flavor and tenderness, ribeye or sirloin are great choices. Ribeye offers more marbling (fat = flavor), while sirloin is leaner but still juicy. Make sure the steak is cooked to medium-rare or medium so it stays tender even after hitting the skillet a second time.
Ingredients for the Steak Grilled Cheese

Steak: Tender cuts like ribeye or sirloin work best for juiciness and flavor.
Cheese: Use a good melting cheese—provolone, mozzarella, or Swiss. A combo of provolone and mozzarella melts like a dream.
Caramelized Onions: These bring a soft sweetness that balances the savory steak and cheese.
Butter: Essential for that crispy golden crust on the bread.
Bread: Thick-cut sourdough or Texas toast holds up beautifully to the fillings without getting soggy.
Salt & Pepper: Season both your steak and onions to enhance natural flavors.
Garlic (Optional): A subtle rub of garlic adds depth to the steak or even to the buttered bread.
How To Make the Steak Grilled Cheese
Step 1: Sear the Steak
Heat a cast iron skillet over medium-high heat. Season the steak generously with salt and pepper. Sear for about 3-4 minutes per side until medium-rare. Rest for 5 minutes, then slice thinly across the grain.
Step 2: Caramelize the Onions
In the same pan, reduce heat to medium. Add a tablespoon of butter and sliced onions. Cook low and slow for 15-20 minutes, stirring occasionally, until golden and soft. Season lightly.
Step 3: Assemble the Sandwich
Butter one side of each bread slice. On the unbuttered side, layer cheese, sliced steak, caramelized onions, and more cheese. Top with the second slice of bread, buttered side facing out.
Step 4: Grill to Perfection
Wipe the skillet clean and place it over medium heat. Grill each sandwich for 3-4 minutes per side until the bread is golden brown and the cheese is fully melted.
Step 5: Slice and Serve
Let rest for a minute to avoid cheese loss. Slice diagonally for classic diner vibes and serve hot.
How Many Does This Feed?
This recipe yields 2 large sandwiches, generously stuffed—enough to serve 2 very hungry people or 4 when paired with a side. Great for lunch, dinner, or even a weekend brunch twist.
Best Way To Store Steak Grilled Cheese
If you have leftovers (lucky you!), let the sandwiches cool completely. Wrap tightly in foil and refrigerate for up to 2 days. To reheat, use a skillet or oven at 350°F for 8-10 minutes—this keeps the crust crispy and the cheese melty. Avoid microwaving, which softens the bread.
Frequently Asked Questions
Can I use leftover steak?
Absolutely! Leftover grilled or pan-seared steak slices are perfect. Just make sure they’re not overcooked when reheated.
What’s the best cheese for steak grilled cheese?
Provolone, Swiss, mozzarella, or a mix. Cheddar works too but go for a mild or medium so it melts smoothly.
Can I add extras like mushrooms or peppers?
Yes! Sautéed mushrooms, bell peppers, or even jalapeños add extra flavor and texture.
Is this freezer-friendly?
It’s best fresh, but you can freeze assembled, uncooked sandwiches wrapped in foil. Reheat directly from frozen in a skillet over low heat with a lid.
Can I make it dairy-free?
Use vegan butter and dairy-free cheese. The flavor won’t be exactly the same, but it’ll still be satisfying.

Ingredients
170 g ribeye or sirloin steak
2 slices provolone cheese

0.25 teaspoon salt
0.25 teaspoon black pepper
1 small garlic clove optional
Instructions
1. Season the steak with salt and pepper on both sides.
2. Heat a skillet over medium-high heat and sear the steak for 3-4 minutes per side until medium-rare. Let it rest for 5 minutes, then slice thinly against the grain.
3. Reduce skillet heat to medium. Add 1 tablespoon butter and the sliced onion. Cook for 15-20 minutes, stirring occasionally, until onions are caramelized and golden.
4. Butter one side of each bread slice. On the unbuttered side, layer 1 slice provolone, sliced steak, caramelized onions, 1 slice mozzarella, and top with a second bread slice (buttered side out).

Don’t rush the onions—caramelizing takes time for full flavor.
Let the sandwich rest before slicing to avoid losing melty cheese.
