Ingredients List

Here's what you'll need to bring this culinary masterpiece to life. Don’t be intimidated; most of these are kitchen staples or easily accessible:

Beef Tenderloin (1 lb): Look for a center-cut piece, about 1-2 inches thick. Substitution: Sirloin steak can be used, but tenderloin is preferred for its tenderness. For a vegetarian option, consider grilled portobello mushrooms marinated in balsamic vinegar and herbs.
Baguette (1 loaf): Sliced into ½-inch thick rounds. Substitution: Ciabatta bread also works well.
Olive Oil (3 tbsp): Extra virgin olive oil is best for flavor.
Salt and Freshly Ground Black Pepper: To taste.
Bearnaise Sauce (1 cup): Either homemade or store-bought. Recommendation: Homemade Bearnaise is significantly better in taste and quality. If using store-bought, opt for a high-quality brand.
Fresh Tarragon (2 tbsp): Chopped, for garnish. Substitution: Chives or parsley can be used, but tarragon adds the classic flavor.
Garlic (2 cloves): Minced.
Butter (2 tbsp): Unsalted.

Step-by-Step Instructions

Follow these steps carefully to create the perfect Grilled Beef Tenderloin Crostini with Bearnaise Sauce.

Step 1: Prepare the Beef Tenderloin

In a bowl, combine 2 tablespoons of olive oil, minced garlic, salt, and pepper. Rub the mixture all over the beef tenderloin. Let it marinate for at least 15 minutes at room temperature. Pro Tip: Longer marinating (up to 2 hours in the refrigerator) will enhance the flavor even more. Did you know that marinating meat for as little as 30 minutes can increase tenderness by up to 15%?

Step 2: Prepare the Crostini

Brush the baguette slices with the remaining olive oil and sprinkle lightly with salt and pepper. Actionable Tip: You can toast the crostini either in a preheated oven at 375°F (190°C) for 5-7 minutes, or on a grill pan for a smoky flavor. For an extra layer of flavor, gently rub a halved garlic clove over the toasted crostini.

Step 3: Grill the Beef Tenderloin

Preheat your grill (or grill pan) to medium-high heat. Grill the beef tenderloin for 3-5 minutes per side for medium-rare, adjusting the time depending on your desired doneness. Use a meat thermometer to ensure accuracy: 130-135°F (54-57°C) for medium-rare. Personalized Touch: For a more intense sear, use a cast-iron grill pan. Data shows that cast-iron pans retain heat more effectively, leading to better browning and crust on the meat.

Step 4: Let the Beef Rest

Remove the beef from the grill and let it rest for 5 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful result. Insider Tip: Tent the beef loosely with foil while it rests to keep it warm. Research shows that resting meat can improve moisture retention by up to 20%.

Step 5: Assemble the Crostini

Slice the beef tenderloin thinly against the grain. Then, spread a generous spoonful of Bearnaise sauce on each toasted crostini. Top with a slice of grilled beef tenderloin and garnish with fresh chopped tarragon. Dynamic Suggestion: Arrange the crostini artfully on a platter for an elegant presentation.

Healthier Alternatives for the Recipe

Common Mistakes to Avoid

Overcooking the Beef: Use a meat thermometer to prevent overcooking. Overcooked tenderloin becomes tough and dry. Data Insight: Surveys show that overcooked beef is the #1 reason people are dissatisfied with beef dishes.
Not Resting the Beef: Resting allows the juices to redistribute, resulting in a more tender and flavorful result.
Using Low-Quality Bearnaise: The Bearnaise sauce is a key component of this dish. If using store-bought, choose a reputable brand.
Soggy Crostini: Toast the crostini just before serving to prevent them from becoming soggy.

Storing Tips for the Recipe

Beef Tenderloin: Cooked beef tenderloin can be stored in an airtight container in the refrigerator for up to 3 days.
Crostini: Store toasted crostini in an airtight container at room temperature to maintain their crispness for 1-2 days.
Bearnaise Sauce: Homemade Bearnaise sauce is best served fresh. Store-bought Bearnaise can be stored in the refrigerator for up to 5 days.
Prepping Ahead: You can marinate the beef tenderloin up to 24 hours in advance. You can also slice the baguette and prepare the Bearnaise sauce ahead of time. This is a great recipe to easily prep to make sure a dinner party is a success!
