Ingredients:
1 baguette, sliced into ½-inch thick slices
2 tablespoons olive oil
1 lb steak (ribeye or sirloin), cooked to your preference and thinly sliced
2 large onions, thinly sliced
2 tablespoons unsalted butter
1 teaspoon sugar
1 cup shredded Gruyère or mozzarella cheese
Salt and black pepper to taste

3. Assemble the Crostini: Top each toasted baguette slice with a piece of steak, a generous amount of caramelized onions, and shredded cheese.
4. Melt the Cheese: Return the assembled crostini to the oven and bake for 5-7 minutes, or until the cheese is melted and bubbly.

Step-by-Step Guide
Follow these detailed steps for perfect crostini every time. First, ensure your steak is at room temperature before cooking; this promotes even cooking. Season it generously with salt and pepper, then sear in a hot pan or grill to your desired doneness. Let it rest for 10 minutes before thinly slicing against the grain. For the onions, patience is key. Cook them over medium-low heat, stirring only occasionally to allow browning. The sugar helps the process but cannot rush it—truly caramelized onions take a full 20-25 minutes. When assembling, layer ingredients in this order: crispy baguette, a slice of steak (to act as a barrier against sogginess), then the onions, and finally the cheese on top to melt over everything.
Serving Suggestions
These crostini are versatile. Serve them as the centerpiece of a game-day spread alongside wings and dips. For a more elegant cocktail party, pair with a bold red wine like Cabernet Sauvignon or a crisp sparkling wine to cut through the richness. A simple side salad with a vinaigrette dressing provides a refreshing contrast. For a complete meal, serve 4-5 crostini per person alongside a hearty soup like tomato bisque.
How-to Summary
Slice and toast baguette. Sear steak, rest, and slice thinly. Slowly caramelize onions with butter and sugar. Assemble crostini: bread, steak, onions, cheese. Bake until cheese melts. Garnish with parsley and serve warm.
Frequently Asked Questions
Can I prepare any components ahead of time? Absolutely. The caramelized onions can be made up to 3 days in advance and reheated. The steak can be cooked and sliced a day ahead. Assemble and bake just before serving.
What are good substitutes for Gruyère cheese? Mozzarella is a great mild option. For more flavor, try provolone, fontina, or even a blue cheese crumble for a bold twist.
How do I prevent the bread from getting soggy? Ensure your baguette slices are thoroughly toasted until crisp. Also, avoid overloading the toast with wet ingredients and assemble just before the final bake.
Can I use a different cut of beef? Yes. While ribeye and sirloin are ideal for tenderness, you can use thinly sliced flank steak or even high-quality deli roast beef in a pinch.
How should I store leftovers? Store components separately if possible. Assembled leftovers can be refrigerated and reheated in a toaster oven or air fryer to restore some crispness.
Common Mistakes to Avoid
Avoid slicing the bread too thickly, which makes it difficult to eat neatly. Do not rush the onion caramelization; high heat will burn them before they sweeten. Slicing the steak before it has rested will cause all the flavorful juices to run out. Finally, do not skip the final bake—it’s crucial for melting the cheese and marrying all the flavors together.
