Ingredients

Scale
  • 1 whole beef tenderloin (4 to 5 pounds), trimmed
  • 2 tablespoons olive oil
  • 1 tablespoon kosher salt
  • 2 teaspoons freshly cracked black pepper
  • 3 cloves garlic, minced
  • 1 tablespoon fresh rosemary, finely chopped
  • 2 tablespoons butter
  • 1 shallot, finely diced
  • 8 ounces cremini mushrooms, finely chopped
  • 2 cups fresh spinach
  • 2 cloves garlic, minced
  • 1/2 cup breadcrumbs (use panko for a lighter texture)
  • 1/4 cup grated Parmesan cheese
  • 1 teaspoon fresh thyme leaves
  • Salt and pepper to taste

Instructions

  1. Prepare the Tenderloin. Pat the beef tenderloin completely dry with paper towels. Using a long, sharp knife, butterfly the tenderloin. Place it on a cutting board and make a lengthwise cut down the center, about three-quarters of the way through, so you can open it up like a book. Do not cut all the way through. Press it open gently.
  2. Make the Stuffing. In a large skillet over medium heat, melt the butter. Add the shallot and mushrooms and cook until softened and the liquid has evaporated, about 8 minutes. Add the spinach and garlic and cook just until the spinach wilts, about 2 minutes. Transfer the mixture to a bowl and stir in the breadcrumbs, Parmesan, thyme, salt, and pepper. Let it cool slightly.
  3. Stuff and Tie the Roast. Spread the cooled stuffing mixture evenly over the inside of the butterflied tenderloin. Carefully fold the other half of the meat back over the stuffing. Using kitchen twine, tie the roast at 1-inch intervals to secure the stuffing and create a uniform shape. This step is crucial for even cooking.
  4. Season and Sear. Rub the entire outside of the tied roast with olive oil. Mix the salt, pepper, minced garlic, and rosemary together and rub this mixture all over the beef. For a beautiful crust, sear the roast in a hot, oven-safe skillet for 2-3 minutes per side until browned all over.
  5. Roast to Perfection. Transfer the skillet to a preheated 425°F oven. Roast until the internal temperature reaches 130-135°F for medium-rare, which will take about 25-35 minutes depending on the size of your roast. Using a meat thermometer is the only way to guarantee perfect doneness for your dinner main course.
  6. Rest Before Slicing. This is the most important step. Remove the roast from the oven, transfer it to a cutting board, and tent it loosely with foil. Let it rest for a full 15 minutes. This allows the juices to redistribute, ensuring every slice is moist and tender.

Notes

Smart Swaps: For a gluten-free version, use gluten-free breadcrumbs or crushed pork rinds. To make it dairy-free, omit the Parmesan cheese or use a nutritional yeast alternative. If you are not a mushroom fan, try a stuffing of sun-dried tomatoes, basil, and provolone for a different festive twist. The most common error is skipping the resting period. Slicing the roast immediately will cause all the precious juices to run out, leaving you with dry meat. Always rest for at least 15 minutes. Any leftover quick Christmas stuffed beef tenderloin is a gift. Let the meat cool completely, then store it in an airtight container in the refrigerator for up to 3 days.
