Beef Tenderloin

• 1 center-cut beef tenderloin roast (4 to 4½ pounds), trimmed and tied
• 2 teaspoons kosher salt
• 1 teaspoon freshly ground black pepper
• 2 tablespoons avocado oil

Garlic Herb Butter

• 6 tablespoons softened butter
• 6 garlic cloves, minced
• 1 teaspoon finely chopped fresh rosemary
• 1 teaspoon finely chopped fresh thyme

This short list leans into high-protein comfort while keeping the flavors clean and family-friendly.

How to Make It

Bring the Beef to Room Temperature

Remove the beef tenderloin from the refrigerator and let it sit at room temperature for 1 to 2 hours.
This small step helps the roast cook evenly, supporting that tender, protein-rich texture that makes this meal feel restaurant-worthy at home.

Mix the Garlic Herb Butter

In a small bowl, stir together the softened butter, garlic, rosemary, and thyme until smooth.
This herb butter adds rich comfort without overpowering the beef, creating a healthy comfort balance that feels indulgent but intentional.

Prep the Tenderloin

Preheat the oven to 425°F (220°C).
Slice the tenderloin in half if needed, then trim and tie it so it holds its shape perfect for even roasting and easy slicing for a family-style dinner.

Season Simply

Pat the beef dry with paper towels, then season all sides generously with salt and pepper.
This minimal seasoning keeps the meal low carb friendly while letting the beef shine as the main protein.

Sear for Flavor

Heat the avocado oil in a large cast-iron skillet over medium-high heat.
Once shimmering, sear the beef on all sides until deeply golden, about 10 minutes total, building a flavorful crust that locks in juices.

Roast to Perfection

Spread the garlic herb butter generously over the top of the tenderloin.
Transfer the entire pan to the oven and roast for 15 to 20 minutes, depending on your preferred doneness, making this a surprisingly quick healthy dinner idea.

Rest and Slice

Remove the tenderloin from the oven and transfer to a cutting board.
Let it rest for 10 to 15 minutes before removing the twine and slicing into thick, juicy pieces ideal for meal prep or a relaxed family dinner.
