Ingredients
For the Beef
- 3.5–4 lbs beef loin roast (tenderloin or sirloin roast)
- 3 tbsp olive oil or softened butter
- 4 cloves garlic, minced
- 1 tbsp fresh rosemary, finely chopped, plus extra sprigs for garnish
- 1 tbsp fresh thyme, chopped
- 1 tbsp fresh parsley, chopped
- 2 cups beef broth
- 2 tbsp all-purpose flour
- Salt and freshly cracked black pepper, to taste
For the Crispy Roasted Potatoes
- 2 lbs russet or Yukon Gold potatoes, peeled and cut into chunks
- 3 tbsp olive oil or beef tallow
- 1 tsp garlic powder
- Salt and black pepper, to taste
Step-by-Step Instructions
1. Prepare and Season the Beef
Start by preheating your oven to 375°F (190°C).
In a small bowl, combine the olive oil or softened butter with the minced garlic, chopped rosemary, thyme, salt, and black pepper. Mix everything well until the herbs and garlic are evenly distributed.
Place the beef loin roast in a roasting pan. Rub the garlic-herb mixture generously over the entire surface of the roast. Try to coat all sides so that every slice gets plenty of the fragrant garlic and herb flavor.
Fresh rosemary and thyme give the beef a particularly aromatic flavor as it roasts, while the olive oil or butter helps the seasoning adhere to the surface.
2. Prepare the Potatoes
Peel the potatoes and cut them into evenly sized chunks. Keeping the pieces similar in size helps them roast at a similar rate.
Place the potato chunks in a bowl and toss them with 3 tablespoons olive oil or beef tallow, garlic powder, salt, and black pepper.
Make sure each potato piece is lightly coated. Spread the seasoned potatoes in a single layer on a separate baking sheet. Giving the potatoes enough space helps them roast and crisp rather than becoming crowded and soft.
3. Roast the Beef and Potatoes
Transfer both the beef and potatoes to the preheated oven.
Roast the potatoes for 45–50 minutes, until they develop a golden, crisp exterior.
Roast the beef for 50–65 minutes, or until the internal temperature reaches 135°F (57°C) for medium-rare.
The exact roasting time can vary depending on the size and shape of the roast, so using an internal thermometer is the best way to check the beef.
While the beef cooks, its garlic and herb coating becomes fragrant and flavorful, while the potatoes gradually develop crisp golden edges and tender centers.
4. Rest the Beef
Once the beef reaches the desired internal temperature, remove it from the roasting pan.
Transfer the roast to a serving platter and cover it loosely with foil. Let it rest for 15 minutes.
Resting is an important part of the process because it gives the juices time to redistribute throughout the roast. This helps the beef remain juicy and flavorful when sliced.
Avoid cutting into the roast immediately after removing it from the oven.
5. Make the Pan Gravy
While the beef rests, use the roasting pan to make the gravy.
Place the roasting pan on the stovetop over medium heat.
Whisk 2 tablespoons all-purpose flour into the pan drippings and cook for about 1 minute. This helps the flour blend with the flavorful drippings and creates the base for the gravy.
Gradually pour in the 2 cups beef broth, whisking continuously as you add it. Continue whisking to help prevent lumps.
Bring the mixture to a simmer and cook for 3–5 minutes, stirring and whisking as needed, until the gravy becomes smooth and thickened.
Taste and season with salt and freshly cracked black pepper as needed.
The pan drippings from the roasted beef give this simple gravy a deep, savory flavor that pairs beautifully with both the beef and potatoes.
6. Slice and Serve
After the beef has rested for 15 minutes, remove the foil.
Using a sharp knife, slice the beef roast into thick rounds.
Arrange the slices on a serving platter and spoon the warm pan gravy over the top. Garnish with fresh rosemary sprigs and chopped herbs.
Serve the roasted beef alongside the crispy roasted potatoes while everything is warm.
Helpful Tips
Use a meat thermometer: For this recipe, the beef is roasted until it reaches 135°F (57°C) for medium-rare. A thermometer provides a more reliable result than judging doneness by time alone.
Give the potatoes space: Spread the potato chunks in a single layer rather than piling them together. This gives their surfaces room to brown and crisp.
Don’t skip the resting time: Allowing the beef to rest for 15 minutes helps keep the slices juicy.
Whisk the gravy continuously: Add the beef broth gradually while whisking to create a smooth gravy.
Use fresh herbs: Fresh rosemary, thyme, and parsley bring a bright, aromatic flavor to the roast and also make the finished platter look beautiful.
