Thyme and Spice Rubbed Roast Beef Tenderloin Au Jus

The memory is still so vivid: the aromas of my grandmother’s kitchen on Christmas Eve, a symphony of savory scents swirling together. Among the stars of her festive spread, the roast beef tenderloin always reigned supreme. She had a special touch, a way of coaxing out the most incredible flavors. The rich, perfectly seared crust, the tender, rosy interior, and that unforgettable au jus…it wasn’t just a meal; it was an experience, a tradition that symbolized warmth, love, and togetherness. Now, I’m excited to share with you a recipe that captures the essence of that cherished memory.

Recipe Overview

Prep Time: 24 hours 15 minutes
Cook Time: 35 minutes
Total Time: 24 hours 50 minutes
Servings: 7
Yield: Approximately 3 ounces of beef per serving
Dietary Type: Generally gluten-free and dairy-free (ensure beef broth is gluten-free)

Ingredients

1 tablespoon thyme, chopped
1 1⁄4 teaspoons salt
1⁄2 teaspoon ground black pepper
1⁄4 teaspoon ground allspice
1 3⁄4 lbs beef tenderloin, trimmed
Cooking spray
1⁄3 cup brandy
1⁄4 cup shallot, minced
1 1⁄2 cups nonfat beef broth

Equipment Needed

Small bowl
Plastic wrap
Large nonstick skillet
Roasting rack
Roasting pan
Thermometer

Instructions

In a small bowl, combine 2 teaspoons of the chopped thyme, salt, pepper, and allspice. This is your flavorful dry rub that will permeate the beef tenderloin.
Rub the mixture evenly over all sides of the beef tenderloin, ensuring every surface is coated. This step is crucial for developing a flavorful crust during roasting.
Wrap the seasoned beef tenderloin tightly in plastic wrap. This allows the spices to penetrate the meat and tenderize it as it rests.
Refrigerate the wrapped beef tenderloin for 24 hours. This extended marinating time is key to achieving optimal flavor and tenderness.
Preheat your oven to 400 degrees Fahrenheit (200 degrees Celsius). Make sure your oven rack is positioned in the center for even cooking.
Heat a large nonstick skillet over medium-high heat. The skillet needs to be hot enough to achieve a good sear without burning.
Coat the pan lightly with cooking spray. This prevents the beef from sticking and helps to develop a beautiful brown crust.
Add the beef tenderloin to the hot skillet and cook for 5 minutes, turning to brown on all sides. Aim for a deep, rich brown color on each side for maximum flavor.
Transfer the seared beef tenderloin to a roasting rack coated with cooking spray. This elevates the beef and allows for even heat circulation during roasting.
Place the rack with the beef in a roasting pan. This will catch any drippings and make cleanup easier.
Bake for 26 minutes, or until a thermometer inserted into the thickest part of the tenderloin registers 135 degrees Fahrenheit (57 degrees Celsius) for medium-rare, or until it reaches your desired degree of doneness. Remember that the internal temperature will continue to rise slightly as the meat rests.
Remove the roasted beef tenderloin from the oven and let it stand for 10 minutes before slicing. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
Carefully pour the brandy into the roasting pan, scraping the pan to loosen any browned bits stuck to the bottom. These browned bits are packed with flavor and will form the base of your au jus. Set aside.
Heat the skillet you used for searing over medium heat.
Coat the skillet with cooking spray again.
Add the minced shallots to the skillet and cook for 4 minutes, or until tender, stirring occasionally. Shallots add a delicate sweetness to the au jus.
Add the brandy mixture (from the roasting pan), beef broth, and the remaining 1 teaspoon of thyme to the skillet, scraping the pan to loosen any remaining browned bits.
Simmer the mixture until it’s reduced to 1 cup (about 4 minutes). This concentrates the flavors and creates a rich, savory au jus.
Slice the beef tenderloin and serve immediately with the warm au jus.

Expert Tips & Tricks

Don’t skip the refrigeration step! It allows the flavors to penetrate deeply and tenderizes the meat.
Use a reliable meat thermometer. This is the best way to ensure your roast is cooked to your desired level of doneness.
Sear the beef properly. A good sear creates a beautiful crust and adds a depth of flavor.
Let the roast rest. This allows the juices to redistribute, resulting in a more tender and flavorful roast.
For an even richer au jus, consider adding a tablespoon of butter at the end.

Serving & Storage Suggestions

Arrange the sliced roast beef on a platter and drizzle generously with the warm au jus. Garnish with fresh rosemary and thyme sprigs for an elegant presentation. This dish pairs beautifully with mashed potatoes, roasted vegetables (such as asparagus or Brussels sprouts), or a simple green salad.

Leftovers can be stored in an airtight container in the refrigerator for up to 3 days. Reheat gently in a skillet or microwave, adding a little extra beef broth if needed to prevent drying. The au jus can also be stored separately in the refrigerator. It is not recommended to leave cooked meat at room temperature for more than 2 hours. For longer storage, consider freezing the cooked beef in a freezer-safe container for up to 2 months.

For a spicier au jus, add a pinch of red pepper flakes.
If you’re looking for a low-sodium option, use low-sodium beef broth and reduce the amount of salt in the rub.
