Lobster Tenderloin

I’ve always believed that special occasions call for a dish that truly impresses, and this lobster-stuffed beef tenderloin never fails to steal the spotlight. It brings together the tenderness of filet mignon with the sweet, delicate bite of lobster, all wrapped in smoky bacon. The rich pan sauce ties everything together, making it a memorable centerpiece for any dinner table. And since it’s entirely low-carb, you can savor every bite guilt-free.

Lobster Tenderloin

Ingredients

  • (3 pound) whole beef tenderloin
  • lobster tails
  • tablespoon butter, melted
  • slices bacon
  • cup sliced green onions
  • cup butter
  • cup dry white wine
  • /8 teaspoon garlic salt
  • tablespoon lemon juice

Instructions

  1. Step 1

    I start by preheating the oven to 350°F. I cook the bacon in a skillet over medium-high heat just until pliable, then set it aside. Meanwhile, I boil the lobster tails for 5-6 minutes until bright red, then remove the meat once cooled. I cut a deep pocket into the tenderloin, stuff in the lobster, and drizzle with melted butter and lemon juice. After tying the roast with kitchen twine, I place it in a roasting pan and bake for 35 minutes. Then I lay the bacon on top and continue baking until crisp and the internal temperature reads 135°F. Let it rest 10 minutes. For the sauce, I melt the rest of the butter, add green onions, wine, and garlic salt, simmering until the onions are tender. I slice the roast, pour the sauce over, and serve.

Chef's Tip

I swear by tying the roast snugly with butcher’s twine at even intervals—it helps the tenderloin hold its shape and ensures the lobster stays tucked inside. Never skip the 10-minute rest after roasting; it makes all the difference in juiciness.

Storage Tips

Store leftover sliced tenderloin in an airtight container in the fridge for up to 3 days. The sauce should be kept separate and reheated gently. To reheat the meat, warm it in a 300°F oven or in a skillet with a little broth—this prevents it from drying out.

Variation Tips

For a different twist, try swapping the lobster for jumbo shrimp or sea scallops—they’re just as luxurious and cook in a flash. To balance the decadence, serve this roast with a bright arugula salad dressed in lemon vinaigrette, or keep it indulgent with creamy cauliflower mash. For a surf-and-turf variation, drape each slice with a spoonful of hollandaise.
