Recipe Overview

• Prep Time: 20 minutes
• Cook Time: 60 minutes
• Total Time: 1 hour 20 minutes
• Servings: 6-8
• Yield: 1 tenderloin
• Dietary Type: Not specified

Ingredients

• 3 lbs beef tenderloin
• 1/4 cup butter
• 1 medium onion, finely diced
• 1/2 cup celery, finely chopped
• 1 (4 ounce) can mushrooms, drained
• 1 clove garlic, minced
• 2 cups soft breadcrumbs
• 1 teaspoon salt
• 1/8 teaspoon pepper
• 1/2 teaspoon dried basil
• 1/8 teaspoon dried parsley flakes
• 2 tablespoons Kikkoman teriyaki sauce
• 4 slices thick sliced bacon

Equipment Needed

• Large skillet
• Mixing bowl
• Sharp knife
• Toothpicks
• Roasting pan

Instructions

1. Remove the beef tenderloin from the refrigerator an hour before cooking. This allows the meat to come closer to room temperature, ensuring more even cooking.

2. In a large skillet, melt the butter over low heat. Add the finely diced onion, chopped celery, drained mushrooms, and minced garlic. Sauté these vegetables until the onions and celery are clear and soft, about 8-10 minutes. Stir frequently to prevent burning. The low heat is crucial for drawing out the natural sweetness of the vegetables without browning them too quickly.

3. While the vegetables are sautéing, prepare the breadcrumb mixture. In a mixing bowl, place the soft breadcrumbs. Add the salt, pepper, dried basil, dried parsley flakes, and teriyaki sauce.

4. Add the sautéed onion-celery-mushroom mixture to the breadcrumb mixture in the bowl. Lightly toss until well blended. The mixture should be moist but not soggy. Adjust seasoning to taste if needed.

5. Using a sharp knife, carefully make a lengthwise cut all the way down the tenderloin. The cut should go about 3/4 of the way through the tenderloin, creating a pocket for the stuffing. Be careful not to cut all the way through the bottom.

6. Lightly spoon the stuffing into the pocket you’ve created in the tenderloin. Do not overstuff; you want to be able to close the pocket securely.

7. Once the tenderloin is stuffed, close the pocket securely with toothpicks. Insert the toothpicks perpendicular to the cut, spacing them about an inch apart. This will prevent the stuffing from spilling out during cooking.

8. Lay the bacon slices on top of the stuffed tenderloin. The bacon will add flavor and moisture to the tenderloin as it cooks.

9. Place the stuffed tenderloin in a roasting pan. Bake uncovered at 350 degrees Fahrenheit for 1 hour, or until the internal temperature reaches 130-135 degrees Fahrenheit for medium-rare. Use a meat thermometer to ensure accurate doneness. If you prefer medium, cook until the internal temperature reaches 140-145 degrees Fahrenheit. If the bacon starts to get too dark, you can loosely tent the tenderloin with foil during the last 15 minutes of cooking.

10. Once cooked to your desired doneness, remove the tenderloin from the oven and let it rest for at least 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful roast. Remember to remove the toothpicks before slicing and serving.

Expert Tips & Tricks

• For a richer flavor, consider browning the beef tenderloin on all sides in a hot skillet before stuffing it. This adds a beautiful crust and enhances the overall taste.
• If you don’t have Kikkoman teriyaki sauce, you can substitute it with soy sauce and a touch of brown sugar.
• To prevent the breadcrumbs from becoming soggy, use slightly stale bread and avoid adding too much liquid.
• If you like, you can wrap the entire tenderloin in puff pastry for an impressive presentation. Be sure to adjust the cooking time accordingly.
• Experiment with adding different herbs and spices to the stuffing, such as thyme, rosemary, or sage.
• Don’t skip the resting period. This is crucial for achieving a juicy and tender roast.

Serving & Storage Suggestions

Serve the Stuffed Beef Tenderloin sliced into 1/2-inch thick portions. It pairs well with roasted vegetables such as asparagus, Brussels sprouts, or potatoes. A simple pan sauce made with red wine or beef broth can also complement the dish beautifully.

Leftover Stuffed Beef Tenderloin should be stored in an airtight container in the refrigerator for up to 3 days. It can also be frozen for up to 2 months. To reheat, gently warm in a 300°F oven or microwave until heated through. Be careful not to overcook, or the meat will become dry.
