Cooking the perfect beef tenderloin in the oven requires understanding a few key factors: the size of your tenderloin, your desired level of doneness, and your oven's quirks. This guide will help you achieve tender, juicy, and flavorful results every time.
Understanding Beef Tenderloin and Cooking Times
Beef tenderloin is a lean cut known for its incredible tenderness. However, because it's lean, it can easily become dry if overcooked. Precise timing is crucial. The cooking time depends heavily on the thickness of the roast. A thicker roast will naturally require a longer cooking time.
Factors Affecting Cooking Time:
- Thickness of the Tenderloin: A thicker tenderloin needs more time to cook through evenly. Measure the thickness at its widest point.
- Desired Doneness: Rare, medium-rare, medium, medium-well, and well-done all have different temperature targets and corresponding cooking times.
- Oven Temperature: Oven temperatures can vary, so a meat thermometer is your best friend for accurate cooking.
Beef Tenderloin Cooking Time Chart (Approximate)
This chart provides approximate cooking times. Always use a meat thermometer to ensure your beef tenderloin reaches your desired internal temperature.
| Desired Doneness | Internal Temperature (°F) | Approximate Cooking Time (per pound) |
|---|---|---|
| Rare | 125-130°F | 10-15 minutes |
| Medium-Rare | 130-135°F | 15-20 minutes |
| Medium | 135-140°F | 20-25 minutes |
| Medium-Well | 140-145°F | 25-30 minutes |
| Well-Done | 145°F+ | 30+ minutes |
Note: These times are for a tenderloin roughly 2-3 pounds. Larger roasts will require additional cooking time. Smaller roasts might require less.
How to Cook Beef Tenderloin in the Oven: A Step-by-Step Guide
- Preheat your oven: Preheat your oven to 400°F (200°C).
- Prepare the tenderloin: Pat the tenderloin dry with paper towels. Season generously with salt and pepper. You can also add other seasonings like garlic powder, onion powder, or herbs.
- Sear (optional): For enhanced flavor and a beautiful crust, sear the tenderloin in a hot skillet with a little oil before roasting. Sear all sides for about 1-2 minutes per side.
- Roast: Place the seasoned tenderloin in a roasting pan. If you prefer, you can add vegetables like carrots, potatoes, or onions to the pan.
- Monitor the internal temperature: Use a meat thermometer to check the internal temperature of the tenderloin. Insert the thermometer into the thickest part of the roast, avoiding the bone if there is one.
- Rest: Once the tenderloin reaches your desired internal temperature, remove it from the oven and let it rest for at least 15-20 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
- Slice and serve: Slice the tenderloin against the grain and serve immediately.
Tips for Perfect Beef Tenderloin
