Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Béarnaise
Step 1: Prepare the Beef
Remove the beef tenderloin filets from the refrigerator and let them rest for about 30 minutes to reach room temperature. This step is crucial for even cooking. While the beef warms up, you can preheat your grill to medium-high heat, aiming for a temperature between 350-375°F, setting the stage for that perfect sear!
Step 2: Slice and Oil the Baguette
Take a fresh baguette and slice it at a 45-degree angle into ½ inch thick pieces. This angle enhances the surface area for toasting. Brush each side generously with olive oil, which will help create a beautifully toasted, crispy exterior as you grill. Get ready for that delightful crunch that pairs perfectly with the tender beef in your crostini!
Step 3: Grill the Baguette
Place the baguette slices on the preheated grill, cooking for 1-2 minutes on each side. Watch for a golden color and a crispy texture. Once they are lightly charred and toasted, remove them from the grill and sprinkle with a pinch of kosher salt. Set them aside to cool slightly as you prepare for the star of the dish—the beef!
Step 4: Increase Grill Heat for Beef
Adjust your grill to high heat, reaching 450-475°F, to sear the beef tenderloin filets. Season the filets generously with kosher salt and freshly ground pepper to enhance their flavor. Place the beef on the hot grill and cook for about 3-5 minutes per side, monitoring for an internal temperature of 125°F for that perfect medium-rare doneness.
Step 5: Rest the Beef
Once the beef tenderloin is grilled to your desired doneness, carefully remove it from the grill and let it rest on a cutting board for 10 minutes. This resting period allows the juices to redistribute throughout the meat, resulting in an incredibly juicy bite. Meanwhile, you can start preparing your béarnaise sauce.
Step 6: Prepare Béarnaise Sauce
As the grilled beef rests, prepare the béarnaise sauce according to the package instructions, ensuring a smooth and creamy blend. You can also opt for homemade béarnaise sauce if you’re feeling adventurous! This sauce will wonderfully complement the richness of the beef in your irresistible Grilled Beef Tenderloin Crostini.
Step 7: Slice the Beef
After resting, slice the tenderloin into thin, even pieces, about ¼ inch thick. Each slice should display those beautiful grill marks, showcasing the wonderful searing you achieved. These tender pieces will be layered atop the toasted baguette for a luxurious presentation as you assemble your crostini.
Step 8: Assemble the Crostini
With your toasted baguette slices ready and beef sliced, it’s time to assemble. Place a tender piece of grilled beef on each baguette slice, spoon a generous amount of béarnaise sauce on top, and finish with a sprinkle of fresh chives or parsley for color and flavor. Serve immediately to your eager guests for an unforgettable experience!

Make Ahead Options
These Grilled Beef Tenderloin Crostini with Béarnaise Sauce are perfect for meal prep enthusiasts looking to save time on busy weeknights! You can toast the baguette slices up to 12 hours in advance and store them in an airtight container to maintain their crispness. Additionally, the beef tenderloin can be seasoned and grilled up to 3 days ahead; simply reheat gently on the grill or stovetop before slicing. To prepare the Béarnaise sauce, mix it in advance and keep it refrigerated for up to 24 hours; just rewarm it slightly before serving. This way, you’ll enjoy a gourmet appetizer with minimal effort, leaving you more time to savor the evening!

Grilled Beef Tenderloin Crostini with Béarnaise Recipe FAQs
What type of baguette should I use?
I recommend using a fresh baguette for optimal flavor and texture. If you have dietary restrictions, a gluten-free baguette works wonderfully as a substitute. Look for ones with a nice crust for that perfect crunch!
How can I store leftover crostini?
Leftover crostini should be stored in an airtight container in the refrigerator for up to 1 day. The baguette may become less crispy, so I suggest reheating them in the oven to regain some crunch before serving.
Can I freeze the crostini components?
Absolutely! You can freeze the beef tenderloin slices and baguette slices separately for up to 2 months. Use airtight bags for freezing. When you’re ready to enjoy them again, gently reheat the beef in a skillet over low heat and toast the baguette pieces in the oven for that freshly made taste.
What should I do if I overcook the beef?
If you find you’ve overcooked the beef and it’s tough, don’t worry! Slice it thinly against the grain and try serving it with an extra drizzle of béarnaise sauce, which will add moisture and flavor. Pairing with a topping like sautéed mushrooms can also help mask any toughness.
Are there any dietary considerations for the béarnaise sauce?
Yes! If you’re preparing this dish for someone with allergies, check the béarnaise sauce mix ingredients for common allergens such as dairy or preservatives. You might consider making your own sauce using egg yolks, butter, and fresh herbs to ensure it meets dietary needs while being delicious!
What’s the best way to ensure the beef is cooked perfectly?
For perfectly cooked beef tenderloin, I strongly recommend using a meat thermometer. Aim for 125°F for medium-rare. Once off the grill, let the beef rest for 10 minutes before slicing to allow the juices to redistribute. This guarantees tender and flavorful slices every time!
