Make It Your Way

I love making this Juicy Beef Tenderloin Roast Recipe my own by tweaking the herbs or sides based on the season. You can easily customize it to fit your taste and occasion, and I’ll share a couple of my favorite variations below.

Variation: Sometimes I swap rosemary for thyme or add a bit of smoked paprika to the butter mix for a slightly smoky twist that’s fantastic!
Seasonal Twist: During holidays, I add a splash of red wine in the roasting pan to keep the roast moist and create a natural pan sauce afterward.
Dietary Adaptation: If you’re cutting back on butter, try olive oil with garlic and herbs for a lighter but still flavorful roast.

Step-by-Step: How I Make Juicy Beef Tenderloin Roast Recipe

Step 1: Tie and Season Your Roast

Start by tying the beef tenderloin with kitchen twine every 2-3 inches. This isn’t just for looks—it helps the roast cook evenly and keeps its shape. Then, season generously with sea salt and freshly cracked black pepper. Pop it uncovered into the fridge overnight. This dry brine is a game changer for juicy meat.

Step 2: Prepare the Herb Butter Mixture

While the oven is preheating, soften your butter and mix it with minced garlic, chopped rosemary, and dijon mustard. This fragrant butter paste will lock in flavor and add a gorgeous crust as it roasts.

Step 3: Roast at High Heat, Then Flip and Continue

Set your oven to 450º F with steam roast if you have it—it helps keep the roast juicy. Roast the beef for 15 minutes, then flip it carefully, add 10 more minutes, and keep an eye on the internal temperature. Using a meat thermometer, check until it hits your desired doneness: rare (115-120°F), medium rare (120-125°F), or medium (130-135°F). Don’t rush this part; patience pays off big time.

Step 4: Let It Rest Before Slicing

Once your roast reaches that perfect temp, take it out and let it rest for at least 10 minutes. This step is crucial—resting lets the juices redistribute, so when you slice into it, each bite is melt-in-your-mouth tender. Resist the urge to cut right away; trust me on this one!

Tips from My Kitchen

Twine Tying: Don’t skip tying your roast—it keeps everything compact and cooks more evenly, which is key for tenderness.
Overnight Seasoning: Leaving the roast uncovered in the fridge overnight dries the surface just enough to get that amazing crust without drying out the meat itself.
Thermometer Use: I always recommend an instant-read probe for accuracy—guesswork here can easily dry out your roast.
Resting Patience: One time I sliced my roast too soon, and it was a juicy disaster—since then I never skip resting for 10 minutes.

Garnishes

I like finishing my beef tenderloin roast with a sprinkle of fresh rosemary leaves and a few flakes of sea salt right before serving. It adds a burst of herbal freshness and a little texture to every bite.

Side Dishes

My favorite side has got to be simple roasted broccoli drizzled with olive oil and seasoned with salt and pepper—quick to roast while the meat rests. Creamy mashed potatoes or a rustic garlic bread also complement the richness beautifully.

Creative Ways to Present

For special dinners, I like slicing the roast into medallions and fanning them out on a warm wooden board with drizzled pan juices and sprigs of thyme. It’s elegant but effortless, perfect for impressing guests without too much fuss.

Make Ahead and Storage

Storing Leftovers

After dinner, I wrap any leftover roast tightly in foil and then plastic wrap before refrigerating. This method keeps the beef moist and prevents it from absorbing fridge odors. It’s best eaten within 3 days.

Freezing

If you want to freeze leftovers, slice the roast first and separate portions with parchment paper before freezing in airtight containers. This way, you can thaw exactly what you want without defrosting the whole batch.

Reheating

For reheating, gentle warmth is key—place slices in a covered dish in a low oven (around 275°F) or microwave briefly at medium power. Adding a splash of beef broth before covering prevents drying out. You’ll still enjoy juicy slices, almost like freshly cooked.

FAQs

How do I know when my beef tenderloin roast is done?

The best way is to use a meat thermometer and check the internal temperature: 115-120°F for rare, 120-125°F for medium rare, and 130-135°F for medium. Remove the roast from the oven as soon as it hits your desired temperature since it will continue to cook slightly while resting.
Can I skip tying the roast?

While you technically can, tying helps the roast maintain shape and cook evenly. Without twine, parts of the beef can cook faster and risk becoming dry. For the best results, I recommend tying.
What if I don’t have a steam roast oven?

No worries! You can use a regular oven. Start by broiling the roast on the center rack for 10 minutes until it browns, then reduce the heat to 450°F and bake until it reaches your desired doneness. Keep a close eye on the temperature with a thermometer.
How long should I let the roast rest?

At least 10 minutes is ideal. This resting period allows the juices inside the roast to redistribute so when you cut into it, they won’t all spill out, leaving you with a dry roast.
