Ingredients for Million Dollar Roast Beef Tenderloin

Here’s all you need to make this showstopper – and yes, every single ingredient matters:

• 1 (4-5 lb) beef tenderloin, trimmed – Ask your butcher to remove the silverskin, or do it yourself with a sharp knife (it’s easier than it sounds!)
• 2 tbsp olive oil – The good stuff, since it’s the flavor base for our herb crust
• 4 cloves garlic, minced – Fresh only, none of that jarred nonsense
• 1 tbsp packed fresh rosemary, finely chopped – Those piney needles make all the difference
• 1 tbsp fresh thyme leaves – No stems! Just run your fingers down the stalks
• 1 tsp salt – Kosher or sea salt, please – table salt will overwhelm
• 1 tsp black pepper – Freshly cracked if you’ve got it

See? Nothing crazy – just a handful of ingredients that play together beautifully. Now let’s make some magic.

Equipment You’ll Need

Don’t worry – no fancy gadgets required! Just grab these basics before you start:

• Roasting pan with rack – Lets heat circulate so you get that perfect crust all over
• Instant-read meat thermometer – Non-negotiable for hitting that perfect medium-rare
• Sharp chef’s knife – Makes trimming the tenderloin a breeze

That’s it! If you’ve got these, you’re ready to roll.

How to Make Million Dollar Roast Beef Tenderloin

Okay, here’s where the magic happens! Don’t let the fancy name fool you – this is easier than you think. Just follow these steps, and you’ll have a restaurant-quality roast that’ll make everyone think you’re a culinary genius.

Step 1: Prep the Tenderloin

First, pat that beautiful hunk of beef dry with paper towels – this helps the crust stick better. Drizzle olive oil all over like you’re giving it a spa treatment, then rub it in with your hands (yes, get messy!). Mix your garlic and herbs in a small bowl – I like to crush them a bit with the back of a spoon to release those amazing oils. Now spread this fragrant paste evenly over every inch of the tenderloin. No bare spots allowed!

Step 2: Roast to Perfection

Preheat your oven to 425°F – no cheating on this step! Place the tenderloin on the rack in your roasting pan, fat side up if there is one. Slide it into the middle of the oven and resist the urge to peek! After about 25 minutes, grab your thermometer and check the thickest part – we’re aiming for 135°F for perfect medium-rare. If it’s not there yet, give it 5 more minutes and check again.

Step 3: Rest and Slice

Here’s the hardest part – you MUST let it rest for 10 full minutes before slicing. I know, I know, it smells incredible, but trust me, this makes all the difference in keeping those juices inside. When it’s time, use a sharp knife to slice against the grain in about ½-inch thick pieces. Watch how the knife glides through like butter – that’s how you know you nailed it!

Tips for the Best Million Dollar Roast Beef Tenderloin

After making this more times than I can count (and surviving a few kitchen disasters), here are my must-know secrets:

• Trim like a pro: Remove all silverskin – it won’t melt and makes slices chewy. Slide your knife under at an angle and it’ll peel right off.
• No fresh herbs? Use 1/3 the amount dried (1 tsp rosemary, 1 tsp thyme), but rub them between your fingers first to wake up the oils.
• Thermometer tricks: Insert it sideways into the thickest part, avoiding the pan below. If it reads 135°F, pull it – residual heat adds 5 more degrees.
• Resting hack: Tent loosely with foil to keep warm without steaming off that gorgeous crust.

Follow these, and you’re guaranteed steakhouse quality every single time!

Serving Suggestions

Here’s how to turn that beautiful tenderloin into a full showstopper meal:

• Creamy mashed potatoes – My go-to for soaking up those juicy drippings
• Roasted asparagus – Tossed with olive oil and lemon while the beef rests
• Yorkshire puddings – Because why not go all out?

For wine? A bold Cabernet Sauvignon stands up to the rich beef, or go with a juicy Pinot Noir if you prefer something lighter. Either way, prepare for compliments!

Storing and Reheating Leftovers

If you somehow have leftovers (seriously, good luck with that), here’s how to keep them tasting amazing:

• Storage: Wrap slices tightly in foil or store in an airtight container for 3-4 days in the fridge. The garlic-herb flavors actually deepen overnight!
• Reheating: Never microwave – it turns tenderloin into shoe leather. Instead, warm slices gently in a skillet with a splash of beef broth or red wine.

Pro tip: Cold leftovers make killer sandwiches with horseradish mayo and arugula. Just saying!

Million Dollar Roast Beef Tenderloin FAQs

I get asked these questions all the time – here’s the scoop from my trial-and-error kitchen adventures!

Can I use dried herbs instead of fresh?

Absolutely! Use 1/3 the amount (1 tsp dried rosemary, 1 tsp dried thyme) and crush them between your fingers to wake up the flavors. But fresh really does make a difference – grab those little herb packets at the grocery store if you can!

How do I cook it well-done without drying it out?

First, I’ll gently suggest medium-rare is perfection – but for well-done, roast until the thermometer hits 155-160°F. To keep it juicy, rub extra olive oil on before cooking and tent with foil while resting. Just know it won’t be quite as buttery-soft.

Can I prep this ahead?

You bet! Rub the herb mixture on up to 24 hours ahead – wrap tightly in plastic and refrigerate. The flavors actually get better! Just let it sit at room temp for 30 minutes before roasting.

What if I don’t have a roasting rack?

No sweat! Arrange thick carrot or celery sticks in the pan as a makeshift rack – they’ll keep the beef elevated AND add flavor to your drippings. Just don’t tell my grandma I suggested this hack!
