Step‑by‑Step Instructions for Tasty Filet Mignon Crostini
Step 1: Prep the Beef
Begin by taking your beef tenderloin (filet mignon) out of the refrigerator, allowing it to rest at room temperature for 30-60 minutes. This step ensures even cooking throughout the meat. While the beef warms up, gather your ingredients and equipment, including a cutting board and a sharp knife, to prepare for the next steps in crafting your Tasty Filet Mignon Crostini.
Step 2: Make Horseradish Sauce
In a mixing bowl, whisk together freshly grated horseradish, sour cream, Dijon mustard, and a pinch of salt until smooth. The combination should be creamy with a spicy kick that will complement the filet mignon beautifully. Once combined, set the horseradish sauce aside, letting the flavors meld while you proceed with the seasoning and cooking of the beef.
Step 3: Season the Beef
Next, prepare a seasoning mix using kosher salt, freshly ground black pepper, granulated garlic, and dried oregano. Coat the filet mignon evenly in canola oil before thoroughly rubbing the seasoning on all sides. This flavorful crust will develop during cooking, enhancing the overall taste of your Tasty Filet Mignon Crostini.
Step 4: Sear the Beef
Heat a cast iron skillet over high heat until it begins to smoke lightly. Carefully place the seasoned filet in the skillet, searing each side and the ends for about 1.5 minutes each. Rotate the beef until the internal temperature reaches approximately 130°F for medium-rare, which should take around 8-12 minutes in total. The filet should have a nice golden crust when done.
Step 5: Rest the Beef
Once seared to perfection, transfer the beef to a plate and tent with aluminum foil. Let it rest for 10 minutes, allowing the juices to redistribute throughout the meat. After resting, slice the filet mignon into 1/4-inch thick pieces. This process ensures that each bite is tender and flavorful in your Tasty Filet Mignon Crostini.
Step 6: Prepare the Baguette
While the beef rests, preheat your broiler. Arrange baguette slices on a baking sheet, then drizzle them with olive oil and sprinkle with kosher salt and granulated garlic. Broil the bread for 1.5-2 minutes until golden brown, flipping halfway through for even toasting. The baguette will provide a crispy base for your luscious crostini.
Step 7: Assemble Crostini
To assemble your Tasty Filet Mignon Crostini, spread a generous layer of the horseradish sauce on each toasted baguette slice. Top with the sliced filet mignon, sprinkle with blue cheese crumbles, and finish with a garnish of chopped fresh parsley. Serve the crostini warm or at room temperature for a delightful appetizer that enchants your guests.

How to Store and Freeze Tasty Filet Mignon Crostini
Fridge: Store leftover crostini components separately in airtight containers for up to 2 days. This helps maintain the baguette’s crispiness and the beef’s tenderness.
Freezer: You can freeze the cooked filet mignon slices for up to 3 months. Wrap them tightly in plastic wrap and aluminum foil to prevent freezer burn.
Reheating: Thaw frozen filet mignon in the fridge overnight. Reheat gently in a skillet over medium heat until warmed through, avoiding overcooking. Reassemble crostini with fresh baguette slices for the best texture.
Assembly Tips: For assembled crostini, it’s best to enjoy them fresh. If stored, reassemble right before serving to ensure that your Tasty Filet Mignon Crostini retains its delightful crunch and flavor.
Make Ahead Options
These Tasty Filet Mignon Crostini are perfect for meal prep enthusiasts! You can prepare the beef and horseradish sauce up to 48 hours in advance. To do this, season the filet mignon and refrigerate it wrapped tightly to prevent drying out, and store the horseradish sauce in an airtight container in the fridge. On the day of serving, sear the beef and let it rest before slicing. Toast the baguette slices just before assembling, so they remain crispy. This approach ensures you can delight your guests with this elegant appetizer while saving precious time on busy evenings!
Expert Tips for Tasty Filet Mignon Crostini
- Use a Meat Thermometer: Avoid overcooking the filet by pulling it at 120°F for medium-rare; remember it continues cooking while resting.
- Hot Skillet Required: Ensure the skillet is hot before adding the beef; this achieves a superb sear without moving it around too much.
- Prepare Sauce in Advance: Allow the horseradish cream to chill overnight; this enhances flavor and creates a harmonious balance with the filet.
- Toast Baguette Carefully: Watch the baguette closely under the broiler; it can go from golden to burnt in mere seconds, so flip halfway through.
- Arrange Artfully: When assembling, layer the ingredients thoughtfully for an elegant presentation; a well-assembled crostini will wow your guests.

Tasty Filet Mignon Crostini Recipe FAQs
What type of filet mignon is best for crostini?
Absolutely! Look for a 7–8 oz piece of beef tenderloin that has a uniform thickness. This ensures even cooking and provides the rich, buttery flavor that filet mignon is known for. Fresh is always best, so try to select cuts that are bright red and nicely marbled for maximum tenderness.
How should I store leftover crostini?
You can store leftover components separately in airtight containers in the fridge for up to 2 days. Keeping the ingredients apart is crucial for maintaining the baguette’s crisp texture and the beef’s tenderness. Bone up on your storage skills by avoiding layering sauces on bread until just before serving!
Can I freeze cooked filet mignon for later use?
Very much so! You can freeze the cooked filet mignon slices for up to 3 months. Begin by wrapping the slices tightly in plastic wrap, followed by aluminum foil to protect against freezer burn. To reheat, thaw the filet in the fridge overnight and then warm gently in a skillet over medium heat until just heated through.
What should I do if my crostini is soggy?
No worries! If your crostini turns out soggy, it could be from too much sauce applied prior to serving. To fix this, re-toast the baguette slices in the oven at a low temperature until they crisp up again. For the future, assemble your crostini just before serving, ensuring each slice retains its intended crunchiness.
Is there a vegetarian option for this recipe?
Absolutely! Although the traditional recipe highlights delicious filet mignon, you can swap it out for grilled portobello mushrooms or marinated grilled eggplant for a vegetarian twist. Simply season and roast or grill these alternatives to achieve a satisfying texture while maintaining the crostini concept.
Can I use different sauces or cheeses in this recipe?
Very! Feel free to get creative. Instead of horseradish sauce, you could make a garlic aioli for a milder flavor profile. Additionally, try swapping blue cheese for goat cheese or even brie if you prefer a creamier option. The versatility of this Tasty Filet Mignon Crostini allows you to personalize it to your taste!
