Ingredients You’ll Need
- 1 French baguette: This is your base; a crusty baguette gives the perfect crunch. Choose a freshly baked one for the best flavor.
- 12 slices London broil: Thinly sliced for the best tenderness. If you can’t find London broil, flank steak or sirloin also works. Just make sure to marinate it for juiciness!
- 1 wedge brie cheese: The creamy texture of brie beautifully balances the savory beef. Look for a high-quality wedge for the richest flavor.
- 20 small fresh thyme sprigs: Fresh thyme adds an aromatic touch. If you’re in a pinch, dried thyme can work too—just use half the amount!
How to Make London Broil Beef Crostini
Preheat Oven: Start your culinary journey by preheating your oven to 350°F. This ensures the baguette gets perfectly crispy.
Slice Baguette: Take your French baguette and slice it into 20 even pieces, about half an inch thick. Lay these slices on a parchment-paper-covered cookie sheet or a cookie sheet with a wire rack. This helps them toast evenly!
Brush with Olive Oil: For extra flavor and crispiness, brush each piece of baguette with a small amount of olive oil or melted butter. This is your secret to achieving that golden-brown perfection.
Bake Crostini: Pop the cookie sheet into the oven and bake for 15-20 minutes, or until the edges turn a light brown. You’ll know they’re ready when your kitchen is filled with a fragrant toasty aroma.
Cool Crostini: Remove the crostini from the oven and allow them to cool for about 3 minutes. You want them crunchy but not too hot to handle!
Assemble Crostini: Top each crispy crostini with a slice of London broil and a small piece of brie cheese. This combination brings layers of flavor that are just out of this world.
Garnish with Thyme: Finally, place a small sprig of fresh thyme on each crostini. This tiny touch not only elevates the dish visually, but it also adds a delightful herbal note.

Storing & Reheating
To keep your London Broil Beef Crostini fresh, store any leftovers at room temperature for up to 2 hours or refrigerate for up to 3 days in an airtight container. For freezing, wrap them tightly in plastic wrap and place them in a freezer bag for up to 3 months. When it’s time to enjoy them again, simply reheat in the oven at 350°F for about 10 minutes, adding a little olive oil to refresh their crunch. The texture may soften slightly, but the flavors will still shine through brightly!
Chef’s Helpful Tips
- Avoid soggy crostini by ensuring the baguette is adequately toasted before adding toppings.
- Make sure your ingredients are at room temperature, especially the brie, for easy spreading onto the crostinis.
- Don’t rush the cooking time; keep an eye on the crostinis to avoid burning them.
- Consider marinating the London broil overnight for enhanced flavor—this is where the magic happens!
- For extra flair, you might drizzle a bit of honey over the brie before adding the thyme for a sweet contrast to the savory flavors.
London Broil Beef Crostini is not just a dish; it’s an experience that brings people together. With every bite, you’ll taste the harmony of crispy bread, juicy beef, and creamy cheese mingling with that fresh herbal touch. Don’t be afraid to play around with the ingredients; maybe try adding some caramelized onions or a splash of balsamic glaze for a twist! Your taste buds are the limit.
