Grilled Beef Tenderloin Crostini Ingredients
For the Baguette
• Baguette – A classic French baguette provides the perfect crunch and base for your Crostini, or opt for a gluten-free version to satisfy all dietary needs.
For the Beef
• Beef Tenderloin Filets – Choose filets that are about 2-inch thick for the juiciest, tender results, delivering a rich flavor that shines through every bite.
• Kosher Salt – Use this to season your beef generously, enhancing its natural flavors beautifully.
• Fresh Ground Pepper – A light touch of freshly ground pepper provides mild heat and complements the richness of the beef.
For the Grilling
• Olive Oil – Brush this on your baguette slices before grilling; it enhances flavor and helps achieve that golden-brown crust we all crave.
For the Sauce
• Béarnaise Sauce Mix – This mix makes preparation easy, lending your crostini a creamy, herb-infused flavor that feels gourmet, or you can whip up your own version for an extra special occasion.
For Garnishing

Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini
Step 1: Prep Beef
Take the beef tenderloin filets out of the refrigerator and allow them to rest at room temperature for about 30 minutes before grilling. This key step ensures even cooking and a juicy result. While the beef warms up, you can prepare your other ingredients, so you’re ready for the next steps.
Step 2: Prep Grill
Preheat your grill to medium-high, ideally between 350°F and 375°F, ensuring it’s hot enough for a perfect sear. You can test the heat by holding your hand above the grill; if you can only hold it there for 3-4 seconds, it’s ready. This will give your Grilled Beef Tenderloin Crostini a beautiful charred flavor.
Step 3: Prepare Baguette
Slice the baguette at a 45-degree angle into ½-inch thick pieces. Lay the slices out on a cutting board, then brush both sides generously with olive oil. This will not only add flavor but will also help achieve a perfect golden-brown toast.
Step 4: Toast Baguette
With the grill preheated, place the baguette slices on the grill for about 1-2 minutes per side, until they’re golden and crisp. Keep an eye on them to avoid burning, as you want a delightful crunch on your Grilled Beef Tenderloin Crostini. Once toasted, sprinkle with kosher salt while they are warm for added taste.
Step 5: Increase Heat
After toasting the baguette, turn your grill heat up to high, approximately 450°F to 475°F. This high heat is crucial for perfectly grilling your beef tenderloin, giving it that desired sear while keeping the inside tender and juicy.
Step 6: Season & Grill Beef
Generously season your beef tenderloin filets with kosher salt and fresh ground pepper. Once the grill is hot, place the filets on it and grill for about 3-5 minutes per side. You’re aiming for a medium-rare doneness, which reaches an internal temperature of 125°F.
Step 7: Rest Meat
Once grilled to perfection, remove the beef tenderloin from the grill and let it rest for 10 minutes. This resting period allows the juices to redistribute within the meat, ensuring each bite of your Grilled Beef Tenderloin Crostini is moist and flavorful.
Step 8: Prepare Sauce
While the beef is resting, prepare the Béarnaise sauce according to the package instructions. If you’re feeling adventurous, you can opt for a homemade version for added richness. This velvety sauce is what truly elevates the flavors of your crostini.
Step 9: Assemble Crostini
To assemble, slice the rested beef tenderloin into thin pieces and layer them on top of the toasted baguette slices. Drizzle the prepared Béarnaise sauce generously over the beef, and sprinkle with fresh chives or parsley for a burst of freshness. Serve your Grilled Beef Tenderloin Crostini immediately, delighting your guests with each beautiful bite.

How to Store and Freeze Grilled Beef Tenderloin Crostini
Fridge: Store any leftover assembled crostini in an airtight container for up to 1 day. The baguette may lose its crispness, so it’s best to enjoy them fresh.
Freezer: To freeze, separate the components—beef, baguette, and sauce. The cooked beef can be frozen for up to 3 months, wrapped tightly. The baguette should be toasted before freezing to maintain texture.
Reheating: Reheat the beef in a skillet over medium heat or microwave gently for a few seconds until warmed through. Toast the baguette slices briefly in the oven for that crispy surface before assembling your Grilled Beef Tenderloin Crostini again.
Make-Ahead Tips: The Béarnaise sauce can be prepared in advance, keeping it in the fridge for up to 3 days. Gently reheat before serving to maintain its velvety consistency.
Expert Tips for Grilled Beef Tenderloin Crostini
- Crisp Baguette: Ensure baguette slices are grilled until perfectly crisp; soggy bread can ruin the texture of your crostini.
- Precise Cooking: Use a meat thermometer to check for doneness; aim for 125°F for medium-rare beef tenderloin for optimal juiciness.
- Prep Ingredients Early: Cut down on stress by preparing all elements ahead of time, including toasting the baguette and making the sauce.
- Perfectly Seasoned: Don’t skimp on salt and pepper when seasoning the beef; proper seasoning enhances the natural flavor and elevates your crostini.
- Garnish with Care: A sprinkle of fresh chives or parsley not only adds color but also freshness, brightening up the rich flavors of your Grilled Beef Tenderloin Crostini.
Make Ahead Options
