Why I Love This Appetizer So Much

Honestly, steak crostini makes me feel like I’m serving restaurant-style appetizers at home without the stress. The best part? You don’t need to overthink anything. Once the steaks cooked and your bread’s toasted, all the fun is in layering the flavors.

You’ve got the buttery richness from the steak, the crispiness from the crostini, and then that pop of flavor from the toppings—whether it’s balsamic glaze, a swipe of horseradish cream, or even a dollop of fig jam. It’s super flexible, and always impressive.

Ingredients You’ll Need

Here’s exactly what I use when I make steak crostini for about 20–24 pieces. You can scale it up or down depending on how many people you’re feeding.

For the crostini base:

• 1 French baguette, sliced into ½-inch rounds (about 20–24 slices)
  
• 1–2 tablespoons olive oil (for brushing the bread)
  

For the steak:

• 1 lb flank, skirt, or sirloin steak
  
• Salt and freshly ground black pepper (for seasoning the steak)
  
• 1 tablespoon olive oil or butter (for cooking)
  

For the creamy layer:

• 1/2 cup whipped goat cheese (or use cream cheese, horseradish sauce, or a mix of mayo + Dijon for a punchy spread)
  

For topping and flavor:

• 2–3 tablespoons fig jam, balsamic glaze, or red onion jam
  
• Fresh herbs – like chopped chives, thyme, or parsley for garnish

Let’s Talk About Steak Cut

For crostini, you want a steak that’s tender and easy to slice thinly. Flank, skirt, sirloin, or filet all work great. Just make sure it’s not overcooked—medium-rare to medium keeps it juicy and flavorful.

How to Make Steak Crostini Step-by-Step

Step 1: Preheat the Oven & Prepare the Bread

1. Preheat your oven to 400°F (200°C). This ensures your crostini get evenly toasted.
   
2. Slice the baguette into ½-inch thick rounds and arrange them on a baking sheet in a single layer.
   
3. Brush both sides lightly with olive oil to help them crisp up.
   
4. Place the baking sheet in the oven and bake for 6–8 minutes, flipping the slices halfway through, until golden and crispy.
   
5. Remove from the oven and let them cool.
   

Step 2: Season & Cook the Steak

1. Generously season both sides of the steak with salt and black pepper. This enhances the flavor and forms a delicious crust.
   
2. Heat a cast-iron skillet or grill over medium-high heat until very hot. You want a good sear!
   
3. Place the steak in the hot pan and cook for about 4–5 minutes per side, depending on thickness and your preferred doneness:
   
   • Medium-rare: 130–135°F (54–57°C)
     
   • Medium: 140–145°F (60–63°C)
     
4. Once cooked, transfer the steak to a cutting board and let it rest for at least 10 minutes. (This step is crucial—it keeps the juices inside!)
   

Step 3: Slice the Steak Properly

1. Find the grain of the steak—these are the muscle fibers running through the meat.
   
2. Slice thinly against the grain (perpendicular to the fibers) to keep the meat tender and easy to bite.
   

Step 4: Assemble the Crostini

1. Spread a small amount of your creamy base (goat cheese, horseradish cream, or cream cheese) onto each toasted baguette slice.
   
2. Top with a slice of steak, making sure it’s evenly placed so every bite is balanced.
   
3. Drizzle with balsamic glaze or fig jam for a sweet and tangy contrast. (You can skip this step if you prefer a more savory flavor.)
   
4. Finish with fresh chopped herbs (thyme, chives, or parsley) for a pop of color and extra flavor.
   
5. Add a crack of black pepper for a final touch.
   

Don’t Worry, Swaps Are Totally Fine

Out of goat cheese? Cream cheese or even hummus works. Don’t like fig jam? Try onion jam, balsamic glaze, or a dollop of pesto. You can also use arugula for a peppery crunch or a sliver of roasted red pepper for sweetness.

This recipe is flexible, so use what you’ve got and make it yours.

Tips to Make It Even Better

• Let the steak rest before slicing—it makes all the difference.
• Don’t overload the crostini. It’s all about balance in one bite.
• Toast the bread until it’s crispy but not rock hard—you want it to hold up without crumbling.
• If you’re making these ahead, wait to assemble until just before serving so the bread stays crisp.

How to Serve Steak Crostini

These are perfect as appetizers, but I’ve honestly made a whole dinner out of them before. They look great on a serving board, especially when you mix up the toppings for variety. Pair with a glass of red wine or even something bubbly, and you’re set.

You can serve them warm or at room temp—either way, they disappear fast.

What to Do with Leftovers

If you’ve got extra steak, save it for wraps, salads, or even breakfast (steak and eggs, anyone?). Toasted bread can be stored in an airtight container and re-crisped in the oven if needed. Assemble crostini fresh for best texture.

FAQs

Can I make the steak ahead of time?
Yes! You can cook the steak a few hours ahead, then slice and reheat gently before assembling. Just don’t microwave it too long or it’ll dry out — a quick warm-up in a skillet with a splash of broth or butter works best.

What’s the best cut of steak to use?
Flank and skirt are my top picks — they’re flavorful and affordable. Sirloin or filet also work well for a more tender bite. Just be sure to slice thinly against the grain.

What kind of bread should I use?
A French baguette is perfect. You want something sturdy that can hold the toppings but still be easy to bite into.

Can I make it without cheese?
Totally! Just skip the cheese and go heavier on the jam or glaze for flavor. Or use hummus or avocado spread as a dairy-free creamy base.

What can I use instead of fig jam or balsamic glaze?
Try caramelized onions, roasted red peppers, tomato jam, or even a little sriracha-honey combo for something spicy-sweet.

How do I keep the crostini crispy?
Only assemble right before serving. If you need to prep earlier, keep the toasted bread and toppings separate, and store the crostini in an airtight container once cooled.

Final Thoughts

This steak crostini recipe is everything I love in an appetizer: simple ingredients, big flavors, and a little room to play. It’s sweet, savory, tangy, and crunchy all at once—and it makes you look like you spent way more time in the kitchen than you actually did.

Whether you’re throwing a party or just craving something special, this one’s a total win.
