How To Cook Bacon Wrapped Beef Tenderloin In Oven
This method focuses on a whole beef tenderloin, also known as a filet mignon roast. Wrapping it in bacon adds fat and flavor, ensuring a juicy and delicious result. The key is proper preparation and careful cooking.
What You’ll Need: Ingredients and Tools
Gathering everything before you start makes the process smooth. Here is your shopping and equipment list.
Ingredients:
- 1 whole beef tenderloin (4 to 5 pounds), trimmed
- 1 pound thin-cut bacon (about 12-16 slices)
- 2 tablespoons olive oil or avocado oil
- 4 cloves garlic, minced
- 2 tablespoons fresh rosemary, chopped
- 1 tablespoon fresh thyme leaves
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- Kitchen twine
Essential Tools:
- Rimmed baking sheet or roasting pan
- Wire rack (that fits inside your baking sheet)
- Sharp knife
- Paper towels
- Instant-read meat thermometer
Step 1: Preparing the Beef Tenderloin
Start by patting the tenderloin completely dry with paper towels. Moisture is the enemy of good browning, so get it very dry. If your butcher hasn’t already trimmed it, remove any thick pieces of silver skin and excess fat.
Next, tuck the thinner “tail” end of the tenderloin underneath itself. This creates a more uniform cylinder shape. Tie it in place with a few pieces of kitchen twine. A even shape cooks evenly, which is crucial.
Step 2: Seasoning and Adding Flavor
In a small bowl, combine the olive oil, minced garlic, rosemary, thyme, salt, and pepper. Mix it into a loose paste. Rub this seasoning paste all over the entire surface of the beef tenderloin.
Make sure you coat every side generously. Let the seasoned beef sit at room temperature for about 30 to 45 minutes. This takes the chill off the meat and promotes more even cooking in the oven.
Step 3: Wrapping with Bacon
Lay your bacon slices side by side on a clean surface, slightly overlapping them. The bacon “weave” should be just a bit wider than the length of your tenderloin.
Place the seasoned tenderloin at one end of the bacon weave. Carefully roll the beef forward, wrapping it snugly in the bacon layer. The bacon should cover the top and sides of the beef.
Place the wrapped roast seam-side down on the wire rack set in your baking sheet. Use a few more pieces of twine to secure the bacon wrap around the beef, tying it at 2-inch intervals.
Step 4: The Cooking Process
Preheat your oven to 425°F (220°C). While it heats, you can let the roast continue to come to room temp. Place the roasting pan in the preheated oven.
Cook for 15 minutes at this high heat. This initial blast helps crisp the bacon and sear the beef. Then, without opening the door, reduce the oven temperature to 375°F (190°C).
Continue roasting until the internal temperature reaches your desired doneness. This is where your meat thermometer is essential. Insert it into the thickest part of the meat.
- For Rare: 120-125°F (49-52°C)
- For Medium-Rare: 130-135°F (54-57°C) Recommended
- For Medium: 140-145°F (60-63°C)
For a 4.5 lb roast, the total cooking time is usually 45 to 55 minutes after reducing the heat. But always trust the thermometer over the clock.
Step 5: Resting and Serving
Once it hits your target temperature, remove the pan from the oven. Transfer the bacon wrapped tenderloin to a clean cutting board. Do not slice it yet.
It is vital to let the meat rest, loosely tented with foil, for at least 15 minutes. This allows the juices to redistribute throughout the roast. If you cut it to soon, all those flavorful juices will run out onto the board.
After resting, carefully remove the twine. Slice the roast into 1-inch thick medallions using a sharp carving knife. Serve immediately while warm.
Pro Tips for the Best Results
Follow these extra tips to make sure your dish turns out perfectly every single time.
- Use a wire rack. Elevating the roast allows hot air to circulate, cooking the bacon evenly on all sides and preventing a soggy bottom.
- Choose thin-cut bacon. Thick-cut bacon won’t crisp up as well and may remain chewy.
- Pat the bacon dry too. Before weaving, lightly pat your bacon slices with a paper towel to remove excess moisture.
- Don’t skip the thermometer. Beef tenderloin is a premium cut, and overcooking it is the biggest mistake. A thermometer guarantees perfect doneness.
- Let it rest. We mentioned it, but it’s worth repeating. Resting is non-negotiable for a juicy roast.
Choosing Your Side Dishes
A great main course needs great sides. Since the oven is busy, choose sides you can prepare ahead or on the stovetop.
- Creamy mashed potatoes or parmesan risotto
- Roasted asparagus or green beans almondine
- Simple garden salad with a vinaigrette
- Sauteed mushrooms or caramelized onions
- Fresh, crusty bread or rolls
These sides complement the rich flavors of the beef and bacon without overwhelming them. They also add color and variety to your plate.
Common Mistakes to Avoid
Even experienced cooks can run into a few pitfalls. Here’s what to watch out for.
- Not Trimming Properly: Leaving the silver skin on can cause the roast to curl and cook unevenly.
- Using Cold Meat: Putting a cold roast straight from the fridge into the oven leads to uneven cooking.
- Overcrowding the Pan: If you add vegetables to the pan, ensure they are in a single layer so they roast instead of steam.
- Slicing Too Soon: Cutting the meat immediately after cooking is the fastest way to end up with dry beef.
- Not Using a Thermometer: Guessing doneness often results in over or undercooked meat.
Make-Ahead and Storage Instructions
Planning ahead can reduce stress on the day of your event.
Make-Ahead: You can season the beef and wrap it in bacon up to one day in advance. Store it covered in the refrigerator. Remember to let it sit at room temperature for about an hour before roasting.
Storing Leftovers: Allow any leftovers to cool completely. Store slices in an airtight container in the refrigerator for up to 3-4 days.
Reheating: To prevent overcooking, reheat slices gently. Place them in a baking dish with a splash of beef broth, cover with foil, and warm in a 300°F (150°C) oven until just heated through.
Frequently Asked Questions (FAQ)
Can I use pork tenderloin instead of beef?
Yes, but the cooking method changes. Pork tenderloin is much smaller and cooks faster. You would need to adjust the time and temperature significantly, and cook it to an internal temperature of 145°F (63°C).
My bacon isn’t getting crispy. What can I do?
If the bacon isn’t as crisp as you’d like after resting, you can use a kitchen torch to gently crisp it up. Alternatively, you can briefly broil the cooked roast, watching it very closely to avoid burning.
How do I cook bacon wrapped beef tenderloin medallions?
For individual medallions, cut the seasoned tenderloin into 2-inch thick slices before wrapping each piece in a half-slice of bacon. Secure with a toothpick. Sear in a hot oven-safe skillet, then finish in a 400°F (200°C) oven for about 10-15 minutes.
What’s the best wine to serve with this dish?
A full-bodied red wine pairs beautifully. Consider a Cabernet Sauvignon, Merlot, or Malbec. The tannins in the wine cut through the richness of the beef and bacon fat nicely.
Can I add a sauce?
Absolutely. A simple pan sauce made with the drippings, some red wine, and beef broth is excellent. A creamy peppercorn sauce or a horseradish cream sauce are also classic and delicious choices.
Final Thoughts
Cooking a bacon wrapped beef tenderloin is an achievable project for any home cook. The combination of careful prep, attentive cooking, and proper resting yields a truly spectacular meal.
It’s a dish that feels luxurious and celebratory. By following these detailed steps, you can confidently prepare a restaurant-quality roast for your next holiday, anniversary, or dinner party.
