Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Béarnaise
Step 1: Prep Beef
Begin by taking your beef tenderloin filets out of the refrigerator and allowing them to sit at room temperature for about 30 minutes. This step ensures even cooking and helps the meat reach the perfect tenderness. While your beef rests, you can prepare the rest of your ingredients for the Grilled Beef Tenderloin Crostini with Béarnaise.
Step 2: Heat Grill
Preheat your grill to medium-high heat, aiming for a temperature between 350°F to 375°F. Ensure your grill grates are clean and lightly oiled to prevent sticking. This grilling temperature will create a beautiful sear on the beef, locking in the juices and flavor.
Step 3: Prepare Baguette
While the grill is heating, slice the baguette diagonally into 1/2-inch slices. Brush each slice generously with olive oil, making sure to coat them evenly for a delicious crispness. Arrange the bread slices on a baking sheet as you prepare to toast them to perfection, which will serve as a delightful base for your crostini.
Step 4: Toast Baguette
Once the grill is ready, place the baguette slices on the grill for 1-2 minutes on each side. Watch for a golden-brown color and light grill marks to form, indicating they are perfectly toasted. While they’re still warm, sprinkle a pinch of kosher salt over each slice to enhance their flavor before moving on.
Step 5: Sear Beef
Now that the baguette is toasted, it’s time to focus on the beef. Increase the grill heat to high (450°F to 475°F). Season the beef tenderloin filets with kosher salt and freshly ground pepper, then place them on the grill. Sear each side for about 3-5 minutes until the internal temperature reaches 125°F for a lovely medium-rare finish.
Step 6: Rest Meat
Once the beef is grilled to your liking, remove the filets from the grill and let them rest for about 10 minutes. This resting period allows the juices to redistribute, ensuring that your meat remains tender and juicy for the Grilled Beef Tenderloin Crostini.
Step 7: Prepare Sauce
While the beef is resting, follow the package instructions to prepare your Béarnaise sauce. This creamy sauce, with its rich herbal flavor, will complement the beef beautifully. Stay near the stove, stirring gently until the sauce reaches a velvety consistency that coats the back of a spoon.
Step 8: Assemble Crostini
With all your components ready, it’s time to assemble the crostini! Slice the rested beef into thin pieces and layer them on the toasted baguette slices. Drizzle the warm Béarnaise sauce generously over the beef, and finish off each creation with a sprinkle of chopped fresh chives or parsley for a vibrant touch. Serve immediately and enjoy the delightful taste of your Grilled Beef Tenderloin Crostini!

Make Ahead Options
These Grilled Beef Tenderloin Crostini with Béarnaise Sauce are perfect for meal prep, allowing you to enjoy gourmet flavors with ease during busy weeknights. You can prepare the baguette slices and Béarnaise sauce up to 24 hours in advance—just store them separately in airtight containers. Alternatively, the beef can be grilled and stored in the refrigerator for up to 3 days; when ready to serve, thinly slice the beef and reheat gently to avoid overcooking. To maintain quality, assemble the crostini just before your event, as this prevents the baguette from getting soggy. This way, you can savor each bite of your delicious Grilled Beef Tenderloin Crostini effortlessly!
How to Store and Freeze Grilled Beef Tenderloin Crostini
Room Temperature: Assembled crostini can be kept at room temperature for up to 2 hours, but it’s best to enjoy them fresh for optimal flavor and texture.
Fridge: If you need to store leftover components, refrigerate separated items for up to 3 days. Keep the beef, baguette, and Béarnaise sauce in airtight containers.
Freezer: For longer storage, freeze the components (grilled beef and baguette) for up to 2 months. Thaw overnight in the fridge and reheat the beef gently before assembling your crostini again.
Reheating: To reheat the beef, warm it up in a skillet over low heat to maintain moisture. The baguette can be briefly toasted again for that fresh crunch in your Grilled Beef Tenderloin Crostini.

Grilled Beef Tenderloin Crostini with Béarnaise Sauce Recipe FAQs
How do I choose ripe beef tenderloin filets?
Absolutely! When selecting beef tenderloin filets, look for good color—fresh meat should have a bright red hue. It’s best to avoid any cuts with dark spots or an off-smell, as these can indicate spoilage. Select filets that are about 2 inches thick, which helps ensure a juicy and tender result when grilled.
What’s the best way to store leftover crostini?
For sure! If you have leftover components, tightly wrap or store them in separate airtight containers in the fridge. The grilled beef and Béarnaise sauce can be kept for up to 3 days. You can store the baguette slices in a resealable bag to help them maintain some of their crunch.
Can I freeze the components of this crostini?
Very much so! You can freeze the grilled beef and any leftover baguette slices for up to 2 months. Just make sure they’re in airtight containers or freezer bags. To use them later, thaw the beef overnight in the fridge and gently reheat it in a skillet over low heat to keep it moist. The baguette can be briefly toasted again to restore its crunch.
What can I do if my Béarnaise sauce is too thick or too thin?
Don’t worry! If your Béarnaise sauce turns out too thick, add a splash of warm water or milk, and stir well to reach the desired consistency. Conversely, if it’s too thin, you can thicken it by cooking it on low heat for a few more minutes while continuously stirring until it reaches a creamier texture. Always taste and adjust seasoning if needed for the best flavor.
Can I make this recipe gluten-free?
Absolutely! To make your Grilled Beef Tenderloin Crostini gluten-free, simply swap the regular baguette with a gluten-free version. Many bakeries offer gluten-free baguettes that crisp up beautifully when grilled. This way, everyone can enjoy your delicious appetizer without worry!
Is the beef tenderloin safe for pets?
Yes, but remember! While cooked, plain beef tenderloin is generally safe for dogs and cats in moderation, avoid giving them any Béarnaise sauce or seasoned beef, as garlic and certain spices can be harmful to pets. Always ask your vet for guidance on introducing new foods to your pet’s diet.
