Step‑by‑Step Instructions for Grilled Beef Tenderloin Crostini with Béarnaise

Step 1: Prep Beef
Begin by removing the beef tenderloin filets from the fridge and letting them sit at room temperature for about 30 minutes. This ensures even cooking when grilled. While you wait, set out your grilling equipment and preheat your grill to prepare for the delicious Grilled Beef Tenderloin Crostini.

Step 2: Preheat Grill
Preheat your grill to medium-high heat, aiming for a temperature between 350-375°F. This will be perfect for toasting the baguette slices. Make sure the grill is clean and ready to give that beautiful sear to both the beef and the crostini.

Step 3: Prepare Baguette
While the grill is heating up, take your baguette and slice it at a 45-degree angle into about 1/2-inch thick pieces. Lightly brush each side with olive oil to enhance flavor and help achieve that perfect golden-brown crust when grilled.

Step 4: Toast Baguette
Once the grill is preheated, place the baguette slices on the grill. Toast each side for 1-2 minutes until they are golden and crisp, monitoring closely to prevent burning. Once toasted, sprinkle a pinch of kosher salt on top as you remove them from the grill to enhance flavor.

Step 5: Increase Heat
After toasting the baguette, turn the grill heat to high, about 450-475°F, to prepare for searing the beef tenderloin. This temperature will lock in the juices and flavor of the meat, setting the stage for a perfect Grilled Beef Tenderloin Crostini.

Step 6: Season and Grill Beef
Season the beef tenderloin filets generously with kosher salt and freshly ground pepper. Place the seasoned filets on the grill and cook for 3-5 minutes on each side, reaching an internal temperature of 125°F for medium-rare. Keep an eye on the meat, looking for a nice sear and grilling marks.

Step 7: Rest Meat
Once cooked to your desired doneness, remove the beef from the grill and transfer it to a cutting board. Let the filets rest for about 10 minutes to allow the juices to redistribute, ensuring they remain tender and flavorful on your Grilled Beef Tenderloin Crostini.

Step 8: Prepare Sauce
While the beef is resting, prepare the Béarnaise sauce according to the package instructions or your homemade recipe if you’re using one. This creamy, herb-infused sauce is the perfect accompaniment to your crostini and should be ready just in time for assembly.

Step 9: Assemble Crostini
To assemble your Grilled Beef Tenderloin Crostini, slice the resting beef into thin pieces. Arrange each slice on the toasted baguette pieces generously. Drizzle with the rich Béarnaise sauce and garnish with freshly chopped chives or parsley, making each bite fresh and vibrant.

How to Store and Freeze Grilled Beef Tenderloin Crostini

Fridge: Store leftover assembled crostini in an airtight container for up to 2 days. The freshness of the baguette may diminish, so it’s best to consume them soon after preparation.

Freezer: For freezing components, individually wrap grilled beef and toasted baguette pieces in plastic wrap, then seal in a freezer bag. They’ll keep for up to 3 months, but once thawed, reassemble and enjoy immediately.

Béarnaise Sauce: If you’ve made homemade Béarnaise sauce, store it in an airtight container in the fridge for up to 3 days. Reheat gently on low heat, stirring until warmed through before serving.

Reheating: To reheat crostini components, simply place the frozen beef in the fridge overnight to thaw, then warm in a skillet or microwave just before assembling.

Expert Tips for Grilled Beef Tenderloin Crostini

Doneness Check: Use a meat thermometer to ensure your beef reaches 125°F for medium-rare; it prevents overcooking and ensures juiciness in your Grilled Beef Tenderloin Crostini.
Perfect Toasting: Grill baguette slices until golden brown to prevent sogginess once toppings are added; lightly brush with olive oil for optimal results.
Assembly Timing: Assemble the crostini just before serving to keep the baguette crisp; this ensures every bite is fresh and delightful.
Herb Variations: Experiment with different fresh herbs like dill or cilantro in place of chives or parsley for a unique flavor twist on your Béarnaise sauce.
Marinating Tips: Consider marinating the beef for 30 minutes with olive oil and herbs before grilling; this can enhance flavor and tenderness in your dish.

What to Serve with Grilled Beef Tenderloin Crostini with Béarnaise?

Create a memorable dining experience by complementing your elegant appetizer with delightful sides and beverages.

Crisp Garden Salad: A refreshing salad with mixed greens, cherry tomatoes, and a light vinaigrette adds brightness and balances the richness of the crostini.
Roasted Baby Potatoes: Seasoned with herbs and garlic, these tender bites offer a comforting warmth that pairs beautifully with grilled beef.
Grilled Asparagus: Lightly charred asparagus drizzled with lemon juice brings a vibrant crunch that complements the smooth Béarnaise sauce.
Garlic Bread: Golden, crusty bread infused with garlic butter makes an indulgent addition, perfect for soaking up any leftover Béarnaise sauce.
Pinot Noir: A glass of this red wine enhances the beef’s rich flavors while being light enough to keep the meal from feeling heavy.
Chocolate Mousse: End on a sweet note with a silky chocolate mousse, its deep richness providing a delightful contrast to the savory crostini experience.

Make Ahead Options

These Grilled Beef Tenderloin Crostini with Béarnaise Sauce are perfect for meal prep, helping you save time during busy gatherings! You can prepare the baguette slices up to 12 hours in advance; simply slice and brush them with olive oil, then store them in an airtight container to keep them fresh. Additionally, Béarnaise sauce can be made up to 3 days ahead – just refrigerate it in a sealed container. When you’re ready to serve, toast the prepped baguette slices on the grill for a quick crisp up, grill the beef for 3-5 minutes per side, and assemble your crostini with the previously made Béarnaise for restaurant-quality results with minimal effort!

Variations of Grilled Beef Tenderloin Crostini

Feel free to let your creativity soar and customize these crostini to suit your taste buds!

Chicken Swap: Replace beef with grilled chicken for a lighter take that still packs a punch in flavor. Juicy grilled chicken can be just as satisfying and works wonderfully with Béarnaise.
Vegetarian Delight: Use grilled portobello mushrooms instead of meat, creating a hearty, umami-filled option. Their rich texture complements the creamy sauce beautifully.
Spicy Kick: Mix sriracha into the Béarnaise sauce for a bold, spicy twist. This unexpected heat will elevate your crostini to a new level of deliciousness.
Pesto Drizzle: Add a drizzle of pesto over the assembled crostini for an herby burst of freshness. It gives a vibrant color and flavor that harmonizes splendidly with grilled beef.
Smoky Flavor: Incorporate smoked paprika when seasoning the beef, infusing a delightful depth of flavor into each bite. This unique twist will surprise your guests and leave them craving more.
Different Cheeses: Try topping with crumbled blue cheese or goat cheese instead of Béarnaise for a creamy, tangy kick. The richness of these cheeses pairs beautifully with the grilled elements.
Extra Crunch: Toss some crispy fried onions on top for an added crunch factor. They add texture and a delightful, savory flavor that makes each bite unforgettable.
Zesty Citrus: Squeeze fresh lemon or lime juice over the assembled crostini for a bright, zesty finish. The acidity will balance the richness of the beef and sauce perfectly.

Grilled Beef Tenderloin Crostini with Béarnaise Sauce Recipe FAQs

How do I select the best beef tenderloin?
Absolutely! When choosing beef tenderloin, look for a darker red color with firm texture and little to no dark spots. Freshness is key, so ensure the meat has a pleasant smell and is from a reputable source. If you can, choose grass-fed or organic options for an even richer flavor!

What’s the best way to store leftover crostini?
Very good question! Store leftover assembled crostini in an airtight container in the refrigerator for up to 2 days. However, keep in mind that the baguette may lose its crispiness. For optimal freshness, it’s better to store components separately and assemble just before serving.

Can I freeze the components of the crostini?
Yes, you can! Wrap each component individually: for the beef, use plastic wrap and then place it in a freezer bag. The toasted baguette slices should be stored in the same way. Both will last up to 3 months in the freezer. When ready to enjoy, thaw the beef in the fridge overnight and reheat it gently while toasting the bread again for that perfect crunch.

What if my Béarnaise sauce thickens too much while reheating?
Don’t worry! If your Béarnaise sauce becomes too thick, simply whisk in a bit of warm water or low-sodium chicken stock to loosen it up. This should help restore its velvety consistency. Remember to heat it on low and stir frequently to avoid breaking the sauce.

Are there any dietary considerations I need to worry about?
Absolutely! For those with gluten sensitivities, opt for a gluten-free baguette. If you’re concerned about allergies, always check the ingredients in store-bought Béarnaise sauce mixes, as they may contain dairy or eggs. If serving to pets, avoid offering any crostini or Béarnaise sauce, as ingredients like garlic can be harmful to them.

How can I customize the toppings for the crostini?
The more the merrier! Feel free to swap out beef for grilled chicken or portobello mushrooms to cater to different dietary preferences. Want to spice things up? Add a drizzle of sriracha to the Béarnaise sauce or a topping of pesto for a fresh herbal kick. Enjoy experimenting!
