Ways to Cook Beef Tenderloin
| Cooking Method | Instructions | Internal Temperature |
|---|---|---|
| Roasting | Preheat oven to 425°F (220°C). Place tenderloin in a roasting pan. Roast for 25-30 minutes for medium-rare or 35-40 minutes for medium. Use a meat thermometer to check doneness. | Medium-Rare: 145°F (63°C) Medium: 160°F (71°C) |
| Grilling | Preheat grill to medium-high heat. Cook tenderloin for 8-10 minutes per side for medium-rare or 12-15 minutes per side for medium. Use a meat thermometer to ensure proper doneness. | Medium-Rare: 145°F (63°C) Medium: 160°F (71°C) |
| Sous-vide | Seal tenderloin in a vacuum bag and place in a water bath. Set water to 131-140°F (55-60°C) for medium-rare or 140-149°F (60-65°C) for medium. Cook for 2-4 hours depending on thickness. | Medium-Rare: 131-140°F (55-60°C) Medium: 140-149°F (60-65°C) |
Resting Is So Important!
Regardless of your cooking method, it’s essential to let the beef tenderloin rest for at least 10-15 minutes before slicing and serving. This will allow the juices to redistribute and the meat to finish cooking, resulting in a more tender and flavorful final product.
This also allows the juices to redistribute throughout the meat. (See my Meat Doneness Chart)
Beef Tenderloin FAQ
How do I use a meat thermometer properly?
Insert the thermometer into the thickest part of the tenderloin, avoiding bone or fat. Wait for the reading to stabilize before checking.
What is carryover cooking?
After removing beef from heat, its internal temperature rises 5–10°F due to residual heat. Always factor this in to avoid overcooking.
Should I rest beef tenderloin?
Yes. Resting 10–15 minutes allows juices to redistribute, making the meat tender and flavorful. Tent loosely with foil to retain warmth.
Can I cook tenderloin from frozen?
It’s not recommended for roasting or grilling—it may cook unevenly. Sous-vide works well from frozen if you extend the cooking time by 30–60 minutes.
How do I season beef tenderloin?
Keep it simple: salt, pepper, garlic, and fresh herbs like rosemary or thyme. Season at least 30 minutes before cooking, or overnight for deeper flavor.
How thick should my tenderloin be?
2–3 inches thick is ideal for even cooking. Thinner pieces cook faster, thicker pieces require longer and may benefit from searing before roasting.
What’s the difference between roasting, grilling, and sous-vide?
- Roasting: High-heat oven, slightly caramelized crust, predictable results
- Grilling: Smoky flavor, crisp exterior, watch for flare-ups
- Sous-vide: Precise temperature, ultra-tender, then sear for crust
How do I know if my beef tenderloin is cooked perfectly?
Use a thermometer for accuracy. Slice the tenderloin to check the center color: pink for medium-rare, light pink for medium, gray-brown for well-done.
Q11: Can I cook beef tenderloin ahead of time?
Yes, you can cook and cool it, then reheat gently in the oven at low heat or sous-vide. Avoid microwaving to prevent drying out.
Q12: How can I prevent beef tenderloin from drying out?
Monitor internal temperature carefully, allow resting, and avoid overcooking. Using butter or olive oil on the exterior helps retain moisture.
Use a Thermometer Please
Types of Thermometers:
- Instant-Read Thermometer – Insert to get a quick reading while cooking. Keep it clean to avoid cross-contamination.
- Oven-Safe Thermometer – Place in the meat before cooking. Leaves oven door closed for steady cooking.
- Probe Thermometer – Digital probe stays in the meat while cooking. Monitor temperature without opening the oven or grill.
How to Use Properly:
- Insert into the thickest part of the tenderloin. Avoid bones and fat.
- Let the thermometer stabilize before reading.
- Check the temperature frequently if using an instant-read thermometer.
Quick Tip:
- Accurate readings are crucial. Proper thermometer use ensures perfectly cooked beef every time.
Where Does Beef Tenderloin Come From?
Beef tenderloin comes from the hindquarters of the cow, specifically near the loin. This part of the cow includes cuts like sirloin, round, and chuck.
The tenderloin sits beneath the ribs, close to the spine. It’s a long, narrow muscle that gets little exercise, making it incredibly tender.
This cut is one of the priciest due to its tenderness and versatility. It can be grilled, roasted, or cut into medallions for pan-frying. It’s a go-to choice for special occasions, holiday meals, and fine dining, and steakhouses often feature it.
In the U.S., beef tenderloin is sold in two main forms: whole or trimmed. A whole tenderloin includes the entire muscle with a thin, fat layer. Trimmed tenderloin has the fat and silver skin removed, leaving a leaner cut. Both versions can be roasted, grilled, or cooked sous-vide for excellent results.

I will be cooking a beef tenderloin roast for about 8 people who like their meat pretty well done. What size roast do I need and how long and what temperature should I cook it? I plan to season it with Lipton Beefy Onion dry soup and cream or mushroom soup for flavor and gravy. I’ve been told that the roast should be trimmed of fat and tied with baker’s twine. I start it at a low temperature and and increase it later or cook it slowly for a longer time at the same low temperature. I do not have a roasting rack. Is it ok to cook it in an aluminum roasting pan. That will make it easier for me to transport a few miles to the place where the lunch will be. Any help/information you can give me will be appreciated. I want it to be done but tender. Thanks so much. I look forward to your prompt response. Linda
For eight people who prefer their beef tenderloin well done, aim for a roast around 5–6 pounds, which allows roughly ¾ pound per person. Trim excess fat and tie it with baker’s twine to ensure even cooking. Season generously with Lipton Beefy Onion soup and a bit of cream or mushroom soup for added flavor and moisture. You can cook it in an aluminum roasting pan—no rack is needed, just make sure it sits on a trivet or crumpled foil to keep it from sticking. For well-done, a slow-and-low approach works best: roast at 275°F (135°C) until the internal temperature reaches about 150–155°F (65–68°C), then optionally increase the oven to 425°F (220°C) for 10–15 minutes to develop a browned crust. Rest for at least 15 minutes before slicing to let the juices redistribute. This method keeps the meat tender even for well-done preferences and makes transport easy.
It is a waste of good meat to cook tenderloin until it is “pretty well done.” There are cheaper cuts that can be cooked to perfection at that and still be good but filet is spoiled passed the “fairly rare” stage, but tenderloin (filet mignon) just gets tough and dry.
I completely agree. Past “fairly rare” it will be cardboard. Just get a Round Roast! Or a few rotisserie chickens or a frozen lasagna LOL!
Completely untrue. If you manage temperature a well done tenderloin or filet can still be very moist and tender. Impatient restaurant and home cooks don’t get this and attempt to cook a medium-well or well tenderloin at the same high temp one would use when going for a crusty rare or medium-rate steak.
I agree but some people like their beef well done.
totally disagree with john 43
I have tasted both done and rare tenderloin and both are yummy, people do have very passionate thing about beef temps, so cook it how you like too PLEASE
The trick is to cook it low and slow. Also use indirect heat if you’re cooking on a grill. I usually cook at 300 to 325 and wait until the Tenderloin is 138 or so. Meets dont have much carry over when you cook them on a low indirect heat.
