Why Temperature Matters for Beef Tenderloin
Beef tenderloin is prized for its tenderness and mild flavor, but it’s also a lean cut, which means it can dry out if overcooked. Hitting the right internal temperature is the key to locking in moisture and achieving your preferred doneness, whether you love it rare or medium-well.
Recommended Internal Temperatures
- Rare: 120–125°F (49–52°C)
- Medium Rare: 130–135°F (54–57°C) (most popular for tenderloin)
- Medium: 140–145°F (60–63°C)
- Medium Well: 150–155°F (65–68°C)
- Well Done: 160°F+ (71°C+)
Pro tip: Always use a reliable meat thermometer for accurate results!
How to Cook Beef Tenderloin Like a Pro
-
Bring to Room Temperature:
Take your beef tenderloin out of the fridge about an hour before cooking. This helps it cook more evenly.
-
Season Generously:
Rub with olive oil, salt, pepper, and your favorite herbs (like rosemary or thyme). Don’t be shy—tenderloin loves bold seasoning!
-
Sear for Flavor:
In a hot skillet, sear the tenderloin on all sides until it develops a rich brown crust. This locks in juices and amps up the flavor.
-
Roast in the Oven:
Transfer to a preheated oven at 425°F (218°C). Roast until your thermometer reads about 5°F below your target doneness—the meat will continue to cook as it rests.
- Example: For medium-rare (target 130–135°F), remove from oven at 125–130°F.
-
Rest Before Slicing:
Tent the roast with foil and let it rest for at least 15 minutes. This lets the juices redistribute, making each bite tender and moist.
The Importance of Resting Your Beef Tenderloin
Don’t skip the resting step! Cutting into your roast too soon will let all those flavorful juices escape, leaving you with dry meat. Resting ensures every slice is juicy and delicious.
Tips for Perfect Beef Tenderloin Every Time
- Invest in a Meat Thermometer: This is your best friend for perfectly cooked beef. Insert it into the thickest part of the roast for an accurate reading.
- Tie It Up: If your roast is uneven in thickness, tie it with kitchen twine so it cooks evenly.
- Add Butter or Garlic: For extra flavor, rub softened butter or minced garlic over the surface before roasting.
- Avoid Overcooking: Tenderloin is best enjoyed medium-rare to medium for maximum tenderness.
- Let It Rest! (Yes, it’s worth repeating.)
Slicing and Serving Suggestions
Use a sharp carving knife to slice the tenderloin against the grain. Serve with classic sauces like béarnaise, red wine reduction, or horseradish cream. Pair with roasted vegetables or creamy mashed potatoes for a complete meal that’s sure to impress!
Frequently Asked Questions
What happens if I cook beef tenderloin past medium?
The meat can become dry and lose its signature tenderness. For best results, aim for medium-rare or medium.
Can I cook beef tenderloin on the grill?
Absolutely! Sear over high heat, then finish on indirect heat until you reach your desired internal temperature. Always use a thermometer for accuracy.
Should I marinate my beef tenderloin?
Tenderloin is already very tender, so marinating isn’t necessary. A simple seasoning rub is usually enough to enhance its flavor.
How long should I rest beef tenderloin?
Aim for at least 15 minutes under foil after roasting. Larger roasts may benefit from up to 20 minutes of resting time.
How do I reheat leftover beef tenderloin?
Reheat gently in a low oven (250°F/120°C) until just warmed through to avoid overcooking. Slices can also be quickly warmed in a skillet with a splash of broth.
