How Long To Cook A 5-Pound Beef Tenderloin? A Chef’s Guide
A 5-pound beef tenderloin, cooked to medium-rare perfection, generally requires approximately 45-60 minutes at 425°F. However, achieving optimal results depends on factors such as oven temperature accuracy and your desired internal temperature.
Unveiling the King of Cuts: Beef Tenderloin
Beef tenderloin, also known as filet mignon or beef fillet, is arguably the most tender cut of beef. Located beneath the ribs, this muscle does very little work, resulting in a melt-in-your-mouth texture. Its delicate flavor profile makes it a blank canvas for various seasonings and cooking methods.
Why Choose Beef Tenderloin? The Benefits
Beef tenderloin offers a myriad of advantages for special occasions or a simple weeknight meal:
- Unparalleled Tenderness: Its hallmark characteristic is its unmatched tenderness.
- Lean Protein Source: It’s relatively low in fat compared to other beef cuts.
- Elegant Presentation: Its cylindrical shape makes for a visually appealing dish.
- Versatile Cooking Methods: It can be roasted, grilled, pan-seared, or even used in wellington.
- Quick Cooking Time: Despite its size, tenderloin cooks relatively quickly.
The Perfect Roast: A Step-by-Step Guide
Roasting a 5-pound beef tenderloin is a straightforward process that yields impressive results. Here’s a detailed guide:
Preparation:
- Remove the tenderloin from the refrigerator at least 30 minutes before cooking to allow it to come to room temperature.
- Preheat your oven to 425°F (220°C).
- Trim any excess silver skin (a tough membrane) using a sharp knife.
- Pat the tenderloin dry with paper towels. This helps achieve a better sear.
Seasoning:
- Generously season the tenderloin with salt and freshly ground black pepper. Don’t be afraid to be liberal; this is a large piece of meat.
- Consider adding other seasonings, such as garlic powder, onion powder, dried herbs (thyme, rosemary), or a spice rub.
Searing (Optional but Recommended):
- Heat 1-2 tablespoons of high-heat oil (such as avocado or grapeseed oil) in a large oven-safe skillet over high heat.
- Sear the tenderloin on all sides until browned, about 2-3 minutes per side. This creates a flavorful crust.
Roasting:
- Place the seared (or unseared) tenderloin in a roasting pan. If you didn’t sear it, place it directly into the preheated pan.
- Insert a meat thermometer into the thickest part of the tenderloin, avoiding any fat or bone.
- Roast for approximately 45-60 minutes, or until the internal temperature reaches your desired doneness.
Resting:
- Remove the tenderloin from the oven and let it rest for at least 10-15 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
- Tent it loosely with foil to keep it warm.
Slicing & Serving:
- Slice the tenderloin against the grain into ¾-inch to 1-inch thick slices.
- Serve immediately with your favorite sides.
Internal Temperature Guide
The key to a perfectly cooked tenderloin is monitoring its internal temperature. Here’s a guide for different levels of doneness:
| Doneness | Internal Temperature (Fahrenheit) | Internal Temperature (Celsius) |
|---|---|---|
| Rare | 125-130°F | 52-54°C |
| Medium-Rare | 130-135°F | 54-57°C |
| Medium | 135-145°F | 57-63°C |
| Medium-Well | 145-155°F | 63-68°C |
| Well-Done | 155°F+ | 68°C+ |
Remember to remove the tenderloin from the oven when it’s about 5-10 degrees below your target temperature, as it will continue to cook during the resting period.
Common Mistakes and How to Avoid Them
Even with the best intentions, mistakes can happen. Here are some common pitfalls and tips for avoiding them:
- Overcooking: The biggest enemy of tenderloin. Use a reliable meat thermometer and err on the side of undercooking. You can always cook it a bit longer if needed.
- Insufficient Seasoning: Tenderloin has a mild flavor, so don’t be shy with the salt, pepper, and other seasonings.
- Skipping the Sear: Searing creates a beautiful crust and adds depth of flavor.
- Cutting into the Meat Too Soon: Resting is crucial for retaining moisture. Be patient!
- Uneven Cooking: Ensure the tenderloin is a uniform thickness. If not, tuck the thinner end under to help it cook evenly.
