Follow these step-by-step instructions to prepare a perfect Lingonberry Glazed Beef Tenderloin:

Preparing the Beef Tenderloin

1. Preheat the Oven: Set your oven to 400°F (200°C) to ensure it’s hot and ready for roasting.
2. Season the Tenderloin: Rub the beef tenderloin with olive oil, ensuring an even coating. Sprinkle salt, black pepper, minced garlic, and chopped rosemary all over the beef.
3. Sear the Tenderloin: In a large ovenproof skillet, heat some olive oil over medium-high heat. Add the beef tenderloin and sear each side for about 2-3 minutes until it’s browned all over.
4. Transfer to the Oven: Once seared, place the skillet with the beef tenderloin into the preheated oven. Roast for approximately 20-25 minutes, or until the internal temperature reaches your desired level of doneness (135°F for medium-rare).

Preparing the Lingonberry Glaze

5. Combine Glaze Ingredients: In a saucepan over medium heat, combine the lingonberry jam, balsamic vinegar, red wine, Dijon mustard, brown sugar, and cinnamon. Stir until well combined.
6. Simmer the Glaze: Bring the mixture to a simmer, stirring occasionally. Let it cook for about 10 minutes, or until it thickens to a syrupy consistency.
7. Brush the Glaze: Remove the beef tenderloin from the oven and brush it generously with the lingonberry glaze.
8. Rest the Beef: Let the glazed beef tenderloin rest for about 10 minutes before slicing. This allows the juices to redistribute, ensuring a tender and juicy result.
