Beef Tenderloin With Boursin Aujus: A Culinary Symphony

I’ll never forget the first time I tasted beef tenderloin with a creamy Boursin sauce. It was at a small bistro tucked away on a cobblestone street during my culinary apprenticeship in Lyon, France. The chef, a gruff but incredibly talented man named Jean-Pierre, insisted I try his signature dish. The tender, perfectly seared beef, combined with the rich, herby Boursin au jus, was a revelation. It was an explosion of flavor and texture that elevated the humble beef tenderloin to something truly extraordinary. That meal sparked my lifelong passion for creating unforgettable culinary experiences, and this recipe is my homage to that first bite of perfection.

Recipe Overview

• Prep Time: 5 minutes
• Cook Time: 30 minutes
• Total Time: 35 minutes
• Servings: 6
• Dietary Type: Not Gluten Free

Ingredients

• 36 ounces beef tenderloin
• 2 tablespoons beef base
• 2 cups water
• 8 ounces Boursin cheese
• 1 tablespoon pepper
• 6 parsley sprigs

Equipment Needed

• Small pot
• Grill or grill pan
• Tongs

Instructions

1. Begin by preparing the Boursin au jus. In a small pot, bring 2 cups of water to a boil.
2. Add 2 tablespoons of beef base to the boiling water and stir until dissolved.
3. Reduce the heat to low and add 8 ounces of Boursin cheese.
4. Stir continuously until the Boursin cheese is fully melted and the mixture reaches a consistency similar to a thin gravy. Keep warm over low heat. Be careful not to scorch the sauce.
5. While the sauce simmers, prepare the beef tenderloin medallions. Cut the 36 ounces of beef tenderloin into six equal portions, approximately 6 ounces each.
6. Liberally crust both sides of each medallion with 1 tablespoon of pepper. Gently press the pepper into the surface of the meat to ensure it adheres well.
7. Preheat your grill or grill pan to medium-high heat.
8. Place the pepper-crusted beef tenderloin medallions onto the hot grill.
9. Grill each 6 oz medallion to your desired level of doneness. For medium-rare (approximately 130-135°F), grill for about 4-5 minutes per side. For medium (approximately 140-145°F), grill for about 5-6 minutes per side. Use a meat thermometer to accurately gauge the internal temperature.
10. Once the medallions have reached your desired doneness, remove them from the heat.
11. Allow the beef tenderloin medallions to rest for 5 minutes before serving. This allows the juices to redistribute, resulting in a more tender and flavorful final product.
12. To serve, place each rested beef tenderloin medallion on a plate.
13. Generously top each medallion with the warm Boursin au jus.
14. Garnish with a sprig of fresh parsley for visual appeal.
15. Serve immediately and enjoy!

Expert Tips & Tricks

• Room Temperature Beef: Let the beef tenderloin sit at room temperature for about 30 minutes before grilling. This helps it cook more evenly.
• Don’t Overcook: Beef tenderloin is best served medium-rare or medium. Overcooking will make it tough.
• Sear First: For an extra flavorful crust, sear the medallions in a hot cast iron skillet before transferring them to the grill.
• Adjust Seasoning: Taste the Boursin au jus and adjust the seasoning as needed. You may want to add a pinch of salt, but be mindful of the salt content in the beef base and Boursin cheese.
• Infuse the Au Jus: For an even more complex flavor, add a splash of dry red wine to the Boursin au jus while it simmers.

Serving & Storage Suggestions

This Beef Tenderloin with Boursin Aujus is best served immediately while the beef is still warm and tender and the sauce is creamy. It pairs well with roasted vegetables like asparagus, Brussels sprouts, or potatoes. A side of creamy mashed potatoes or a simple green salad would also be excellent accompaniments.

Leftovers can be stored in the refrigerator in an airtight container for up to 3 days. To reheat, gently warm the beef medallions in a skillet over low heat or in the microwave. Reheat the Boursin au jus separately in a small pot over low heat, stirring occasionally. Avoid overheating the beef, as it can become dry.

It’s generally not recommended to freeze cooked beef tenderloin, as the texture can suffer upon thawing. However, the Boursin au jus can be frozen for up to 2 months. Thaw it overnight in the refrigerator before reheating.
