- Kosher salt (1 teaspoon): Helps season the beef and brings out its natural flavors.

How to Make Irresistibly Juicy Grilled Beef Tenderloin Crostini with Béarnaise Recipe
Step 1: Prepare Your Beef and Baguette
Start by removing the beef tenderloin filets from the fridge around 30 minutes before grilling. This step lets the meat come to room temperature, ensuring an even cook. Meanwhile, slice your baguette diagonally into half-inch thick rounds and brush each slice lightly with olive oil. These details make all the difference in both texture and flavor.
Step 2: Toast the Baguette Slices
Fire up your grill to a medium-high heat between 350 and 375 degrees Fahrenheit. Place the oiled bread slices on the grill and toast for 1-2 minutes per side until they achieve a subtle golden-brown color and a satisfying crunch. This step is crucial to building a sturdy crostini base that won’t get soggy under all the beef and sauce.
Step 3: Sear the Beef to Juicy Perfection
Turn your grill’s heat up to high, aiming for 450 to 475 degrees. Season the beef tenderloin generously with kosher salt and fresh ground pepper. Grill the filets for about 3 to 5 minutes per side, aiming for an internal temperature of approximately 125 degrees Fahrenheit for that tender, juicy medium-rare finish. Rest the meat for 10 minutes off the heat; this lets the juices redistribute and locks in all that incredible flavor.
Step 4: Prepare the Béarnaise Sauce
While your beef rests, prepare the béarnaise sauce according to the package directions or your own recipe. This classic French sauce is buttery with a hint of tarragon and shallots, elevating the tender beef with its rich, tangy, and slightly herbal notes.
Step 5: Assemble the Crostini
Slice the rested beef thinly against the grain and carefully layer the pieces onto each toasted baguette round. Drizzle generously with the béarnaise sauce and finish with a sprinkle of fresh chives or parsley for a pop of color and brightness. Voilà! You’ve created an enticing appetizer that’s bound to impress.

Garnishes
Fresh herbs are your best friend here. Chives and parsley add not only a lovely splash of green but also a mild onion and grassy flavor that lighten and complement the rich béarnaise and beef. For a little extra flair, consider a light dusting of smoked paprika or a few pink peppercorns for visual interest and subtle spice.
Side Dishes
These crostini shine on their own as a stunning appetizer, but pairing them with crisp green salads, roasted vegetables, or even a glass of full-bodied red wine will create a memorable dining experience. Light sides with a hint of acidity balance the richness across the plate effortlessly.
Creative Ways to Present
For entertaining, pile the crostini on rustic wooden boards alongside small bowls of extra béarnaise sauce for dipping. Add edible flowers or microgreens for feminine flair or arrange them on a tiered platter to make the display as eye-catching as it is delicious. Don’t forget to provide cocktail picks to make handling easier and mess-free.
Make Ahead and Storage
Storing Leftovers
Store leftover crostini components separately in airtight containers to keep textures intact—the toasted bread can become soggy if stored with the beef or sauce. The beef slices and béarnaise sauce refrigerate well for up to two days.
Freezing
The beef tenderloin itself can be frozen before grilling if prepared in advance, but freezing assembled crostini or béarnaise sauce is not recommended as it will compromise texture and flavor upon reheating.
Reheating
When ready to enjoy leftovers, reheat beef gently in a warm oven or on a skillet, and warm the béarnaise sauce over low heat while stirring constantly. Toast fresh baguette slices before assembling again for best results.
FAQs
Can I use a different cut of beef?
While tenderloin is ideal for its tenderness and flavor, you can substitute with filet mignon or even sirloin if you prefer. Just be sure to adjust cooking times to avoid overcooking tougher cuts.
Is there a vegan alternative to béarnaise sauce?
Absolutely! You can make a plant-based béarnaise using vegan butter and aquafaba or vegan mayonnaise with fresh tarragon and shallots to maintain the signature flavor while accommodating dietary needs.
Can I prepare this crostini indoors if I don’t have a grill?
Yes! Use a grill pan or your oven’s broiler to toast the bread and sear the beef. A cast-iron skillet can achieve similar delicious caramelization for the tenderloin slices.
How long can I let the beef rest after grilling?
Resting the beef for about 10 minutes is perfect to allow juices to redistribute, but you can let it rest up to 15 minutes if needed. Just cover loosely with foil to keep it warm.
What wine pairs well with this crostini?
Look for a medium-bodied red like Pinot Noir or Merlot. Their fruit-forward profile and moderate tannins complement the richness of the beef and béarnaise beautifully.
