Ingredients You’ll Need

2 pounds beef sirloin: This is the star of the dish. A well-marbled cut ensures juicy, tender meat. Look for fresh cuts at your local butcher or grocery store.
1 pound baby potatoes: Their small size allows them to roast quickly and evenly. You can substitute with regular potatoes, but cut them into smaller pieces.
4 cloves garlic, minced: Adds a robust flavor that compliments the beef perfectly. Fresh garlic is best, but jarred garlic can be used in a pinch.
2 tablespoons olive oil: Helps the seasoning adhere to the meat and potatoes, while also enhancing browning. You could also use melted butter for a richer flavor.
1 teaspoon salt: Essential for enhancing the natural flavors.
1/2 teaspoon black pepper: Just enough to add a little kick without overpowering the dish.
1 teaspoon dried thyme: This herb brings a warm, earthy flavor. Fresh thyme can also be used if available.
1 teaspoon rosemary: Another aromatic herb that pairs beautifully with beef, giving a distinct fragrance and taste.

How to Make Roast Sirloin with Potato Bake

Preheat the oven: Start by preheating your oven to 400°F (200°C). A hot oven is essential for roasting and will help achieve that desirable crust on the beef.

Prepare the herb mixture: In a bowl, mix together 4 cloves of minced garlic, 2 tablespoons of olive oil, 1 teaspoon of salt, 1/2 teaspoon of black pepper, 1 teaspoon of dried thyme, and 1 teaspoon of rosemary. This fragrant paste will coat your sirloin beautifully.

Rub the mixture: Take the 2 pounds of beef sirloin and rub the garlic herb mixture all over it, ensuring an even coating. This step infuses the meat with incredible flavor.

Arrange in a roasting pan: Place the seasoned beef in a roasting pan. Surround it with 1 pound of baby potatoes. The potatoes will soak up those delicious juices as they roast, making them irresistible.

Roast the meat: Now, pop the roasting pan into the oven. Roast for approximately 1 hour, or until the internal temperature reads 135°F (57°C) for a perfect medium-rare result. You’ll know it’s done when the juices run clear, and the meat has a lovely browned exterior.

Rest the beef: Once your roast is perfectly cooked, let it rest for about 10 minutes before slicing. This resting time allows the juices to redistribute throughout the meat, ensuring every bite is juicy and flavorful.

Serve: Slice the beef against the grain and serve it alongside the roasted garlic potatoes. The combination of flavors and textures is guaranteed to wow your friends and family!

Storing & Reheating

To store any leftovers from this savory roast, allow the beef and potatoes to cool completely, then transfer them to an airtight container. In the refrigerator, they will stay fresh for up to 3 days. For longer storage, you can freeze the leftovers for up to 3 months. Just wrap the beef tightly in plastic wrap and place it in a freezer bag. When you’re ready to enjoy it again, simply thaw in the refrigerator and reheat in the oven at 350°F (175°C) until warmed through, about 20-25 minutes. Keep in mind that while the flavor remains delightful, the texture of the potatoes may change slightly.

Chef’s Helpful Tips

Ensure your beef is brought to room temperature before cooking for a more even roast.
Avoid overcooking; using a meat thermometer takes the guesswork out of checking for doneness.
If your potatoes are larger than bite-sized, consider halving or quartering them to speed up cooking.
Experiment with herbs! Fresh herbs offer brighter flavors, so don’t hesitate to mix in some parsley or oregano.
If your roast is cooking unevenly, you can rotate the pan halfway through roasting.
Consider making a simple gravy with the drippings for an extra touch of flavor.

Roasted Beef Sirloin with Garlic Potatoes packs a comforting punch of flavor that’s sure to impress. The ease of preparation combined with the rich, savory taste makes it a perfect dish for any occasion, whether you’re serving family or entertaining special guests. Don’t hesitate to experiment with different seasonings or sides, making it your own. Each time you roast this dish, you’ll uncover new layers of deliciousness waiting to be enjoyed. Happy cooking!

Recipe FAQs

How do I know when the sirloin is perfectly cooked?

Using a meat thermometer is the best way to check for doneness. A medium-rare roast should read 135°F (57°C). Letting it rest for 10 minutes allows it to finish cooking slightly and helps keep those juices locked in.

Can I make this dish ahead of time?

Absolutely! You can prepare the herb mixture and rub it on the beef up to a day in advance. Just cover and refrigerate until you’re ready to roast. This allows the flavors to deepen!

What if I don’t have baby potatoes?

No problem! You can substitute with regular potatoes; just cut them into smaller pieces to ensure they roast evenly and don’t take too long to cook.

Can I add vegetables to the roasting pan?

Yes! Feel free to add carrots, onions, or bell peppers around the beef and potatoes. Just make sure to adjust the cooking time based on the vegetables you choose. They can add extra flavor and color to your dish.
