Ingredients
- 1 French baguette or Italian bread loaf
- 1 pound sirloin steak or ribeye steak
- 1 tablespoon olive oil
- 2 tablespoons butter
- 3 cloves garlic, minced
- 1 teaspoon garlic powder
- 1 teaspoon onion powder
- 1/2 teaspoon smoked paprika
- 1/2 teaspoon salt
- 1/2 teaspoon black pepper
- 1 tablespoon Worcestershire sauce
- 8 slices provolone cheese
- 1/4 cup grated Parmesan cheese, optional
- 1 tablespoon chopped parsley, optional
How to Make Cheesy Steak Crostini
Preheat your oven to 400°F. Line a baking sheet with parchment paper.
Slice the baguette into thick rounds, about three-quarters of an inch thick. Arrange the slices in a single layer on the baking sheet.
Brush the bread lightly with olive oil. Bake for five to seven minutes, turning once, until the bread is lightly crisp and golden.
While the bread toasts, season the steak with garlic powder, onion powder, smoked paprika, salt, and black pepper.
Heat olive oil in a skillet over medium-high heat. Add the steak and cook for about two to three minutes per side, depending on thickness and preferred doneness.
Transfer the steak to a cutting board and let it rest for five minutes. Slice it thinly against the grain.
Reduce the skillet heat to medium. Add butter, minced garlic, and Worcestershire sauce. Stir for about 30 seconds until the garlic is fragrant.
Return the steak slices briefly to the skillet and toss them gently in the garlic butter.
Place a small amount of steak on each toasted bread slice. Top with a piece of provolone cheese.
Return the crostini to the oven and bake for three to five minutes, until the cheese is melted. Broil for one minute if you want small golden spots on top.
Sprinkle with Parmesan and parsley if desired. Serve warm.
Tips for the Best Steak Crostini
Choose a tender steak cut such as sirloin, ribeye, strip steak, or leftover roast beef. Slice it thinly so it is easy to bite through on the toast.
Let the steak rest before slicing. This helps the juices remain in the meat instead of running onto the bread.
Toast the bread before adding the steak. A crisp base holds the toppings better and prevents sogginess.
Do not overcook the steak. It will warm again under the broiler, so keep it slightly less done than your final preferred level.
Easy Variations
For Philly cheesesteak crostini, add sautéed onions, bell peppers, and mushrooms. Use provolone cheese for the classic flavor.
For garlic mushroom steak crostini, sauté sliced mushrooms in butter and place them over the steak before adding the cheese.
For spicy steak crostini, add sliced jalapeños, crushed red pepper flakes, hot sauce, or pepper jack cheese.
For a blue cheese version, use crumbled blue cheese instead of provolone and add caramelized onions.
For barbecue steak crostini, toss the steak in barbecue sauce and use cheddar cheese.
What to Serve With Steak Crostini
Serve these steak crostini with a green salad, Caesar salad, roasted vegetables, fries, or potato wedges.
For a party platter, add other finger foods such as stuffed mushrooms, cheese cubes, vegetable sticks, dips, and mini sliders.
They also work beautifully with a bowl of tomato soup, creamy mushroom soup, or a fresh cucumber salad.
Make-Ahead Instructions
The bread can be sliced and toasted a few hours ahead. Keep it in an airtight container at room temperature.
The steak can be cooked and sliced one day ahead, then stored in the refrigerator. Reheat it gently with butter before assembling the crostini.
For the best texture, melt the cheese and serve the crostini just before eating.
Storing Leftovers
Store leftover steak and toasted bread separately when possible. Keep the steak in an airtight container in the refrigerator for up to three days.
Reheat the steak gently in a skillet. Toast the bread again in the oven, assemble with cheese, and bake until melted.
Assembled crostini can be refrigerated for up to one day, but the bread will be softer after reheating.
Common Mistakes to Avoid
Do not use very thin sandwich bread. Choose a crusty baguette or Italian loaf that can hold the steak and cheese.
Avoid placing very hot steak directly on untoasted bread. Toasting first helps the crostini stay crisp.
Do not overfill each slice. A moderate amount of steak and cheese makes the crostini easier to serve and eat.
Watch carefully when broiling. Provolone cheese can brown quickly under high heat.
Frequently Asked Questions
Can I use leftover steak?
Yes. Leftover grilled steak, roast beef, or steak bites are perfect for this recipe.
What cheese works best?
Provolone is a great choice because it melts smoothly and pairs beautifully with steak. Mozzarella, Swiss, cheddar, Monterey Jack, and pepper jack also work well.
Can I make these with chicken?
Absolutely. Use cooked sliced chicken and prepare the same way with garlic butter and melted cheese.
Can I make them in an air fryer?
Yes. Toast the bread first, add steak and cheese, then air fry at 375°F for two to three minutes until the cheese melts.
How do I keep the crostini crispy?
Toast the bread before adding toppings, avoid watery sauces, and serve soon after baking.
