Ingredients
(Tip: You’ll find the full list of ingredients and measurements in the recipe card below.)
beef tenderloin salt black pepper ground cocoa powder (unsweetened) fennel seeds (crushed) garlic olive oil butter
For the red wine sauce:
red wine beef stock shallots butter flour (optional, for thickening) fresh thyme salt black pepper
Directions
Start by preparing the beef tenderloin. Pat it dry and season generously with salt and black pepper. In a small bowl, mix cocoa powder, crushed fennel seeds, and minced garlic, then rub this mixture evenly over the surface of the meat.
Heat olive oil in a large skillet over medium-high heat. Sear the beef on all sides until a rich brown crust forms. Transfer the tenderloin to a preheated oven and roast until it reaches your desired level of doneness.
While the beef is roasting, prepare the red wine sauce. In the same pan, sauté finely chopped shallots until softened. Pour in the red wine, scraping up any browned bits, and let it reduce by about half. Add the beef stock and thyme, then simmer until slightly thickened. If needed, whisk in a small amount of butter or flour to reach the desired consistency. Season with salt and pepper.
Once the beef is cooked, remove it from the oven and let it rest for several minutes before slicing. This helps retain the juices.
Slice the tenderloin and serve with the red wine sauce drizzled over the top.

Variations
You can add a touch of brown sugar to the cocoa fennel crust for a slightly sweeter profile. Substitute rosemary for thyme in the sauce for a different herbal note. For added depth, include a splash of balsamic vinegar in the sauce. If you prefer a spicier crust, incorporate a pinch of chili flakes.
Storage/Reheating
Store leftover beef in an airtight container in the refrigerator for up to 3 days. Keep the sauce separate for best results.
To reheat, gently warm the beef in a low oven or skillet to avoid overcooking. Reheat the sauce on the stovetop, adding a bit of stock if it becomes too thick.
