Ingredients
For the Beef Tenderloin Roast
- 1 center-cut beef tenderloin roast (4 to 4 ½ pounds) (trimmed and tied)
- 2 teaspoons kosher salt
- 1 teaspoon freshly ground black pepper
- 2 tablespoons avocado oil
For the Herb Mixture
- 6 tablespoons softened butter
- 6 garlic cloves (minced)
- 1 teaspoon finely chopped fresh rosemary leaves
- 1 teaspoon finely chopped fresh thyme leaves
How to Make Beef Tenderloin Roast (Herbed Garlic Butter)
Step 1: Prepare the Beef
Remove the beef tenderloin from the fridge and let it come to room temperature prior to cooking, about 1 to 2 hours.
Step 2: Mix the Herb Butter
In a small bowl, mix together the softened butter, minced garlic, chopped rosemary, and thyme. Set this flavorful mixture aside.
Step 3: Preheat the Oven
Preheat your oven to 425°F (220°C). Slice the beef tenderloin in half if needed, then trim any excess fat. Use kitchen twine to tie it up securely if it hasn’t been done by your butcher.
Step 4: Season the Beef
Use paper towels to pat any excess moisture from the beef tenderloin. Then season both sides generously with kosher salt and freshly ground black pepper.
Step 5: Sear the Beef
Heat avocado oil in a large cast-iron pan over medium-high heat. Once shimmering, add the beef tenderloin. Sear for about 10 minutes total, browning all sides until a golden brown crust forms.
Step 6: Add Herb Butter
Slather your prepared herb butter mixture over the top side of the seared beef tenderloin. Transfer your entire cast-iron pan into the preheated oven. If using a probe thermometer, insert it before placing in the oven.
Step 7: Roast
Roast for 15 to 20 minutes based on your preferred level of doneness. For best results, monitor with your meat thermometer.
Step 8: Rest & Serve
Once cooked to perfection, remove from oven and transfer to a cutting board. Let it rest for 10 to 15 minutes to allow juices to redistribute before slicing into 1-inch thick pieces. Optionally serve with horseradish sauce for added flavor.

How to Perfect Beef Tenderloin Roast (Herbed Garlic Butter)
Perfecting your beef tenderloin roast requires attention to detail. Here are some tips to ensure you achieve a delicious result every time.
- Use Room Temperature Meat – Letting the beef come to room temperature before cooking helps it cook more evenly.
- Season Generously – Don’t be shy with salt and pepper; seasoning enhances the natural flavors of the meat.
- Create a Crust – Searing the beef in a hot pan before roasting develops a beautiful crust that locks in juices.
- Monitor Internal Temperature – Use a meat thermometer for precise doneness; aim for 125°F (52°C) for medium-rare.
- Rest Before Slicing – Allowing the roast to rest for 10-15 minutes redistributes juices for moist slices.
- Experiment with Herbs – While rosemary and thyme are great, feel free to mix in other herbs like parsley or oregano for variation.

- Wild Rice Pilaf – Nutty wild rice mixed with herbs provides an earthy contrast to the rich meat.
- Creamed Spinach – This rich side dish offers a creamy texture that balances out the savory beef flavors.
- Corn on the Cob – Grilled or boiled corn is a sweet addition that complements beef perfectly during summertime meals.
Common Mistakes to Avoid
Cooking a Beef Tenderloin Roast (Herbed Garlic Butter) can be simple, but there are common pitfalls that can lead to less-than-perfect results.
- Bold seasoning: Skipping the seasoning can result in bland meat. Always season generously with salt and pepper for enhanced flavor.
- Ignoring room temperature: Cooking cold meat straight from the fridge can lead to uneven cooking. Let your beef tenderloin sit at room temperature for 1 to 2 hours before cooking.
- Overcooking: Cooking the roast too long will dry it out. Use a meat thermometer to ensure you achieve your desired doneness.
- Skipping the rest period: Cutting into the roast immediately after cooking causes juices to run out. Allow it to rest for 10 to 15 minutes before slicing.
- Neglecting the crust: A good sear adds texture and flavor. Make sure to brown all sides of your beef tenderloin in a hot pan before roasting.
